Answer:
I would say maybe B and C but im not a 100%
Explanation:
In an Antarctic pelagic community, the primary producers are phytoplankton, which serve as food for the dominant grazing zooplankton, especially krill and copepods, both of which are crustaceans.
These zooplankton species are in turn eaten by various carnivores, including other plankton, penguins, seals, fish, and baleen whales. Squids, which are carnivores that feed on fish and zooplankton, are another important link in these food webs, as they are in turn eaten by seals and toothed whales (Figure 1).
Figure 1: Arrows follow the transfer of food from the producers (phytoplankton) up through the trophic levels. For simplicity, this diagram omits decomposers.
Antarctic krill (Euphausia superba) is an important source of food for whales, seals, squid, fish, and many species of birds. Its abundant biomass is one of the largest on Earth. Figure 2 compares the effects of krill harvesting on species richness within two small sections of the Antarctic region; one section was subject to krill harvesting and the other section was not.
Describe how the autotrophs facilitates the flow of energy through the Antarctic ecosystem. In the Antarctic pelagic community, there are three types of seals. The leopard seals eat birds, but the crabeater and elephant seals do not. Explain how the interactions between seals and other species may affect their food sources.
Identify the independent variable of the data graphed in Figure 2. Explain one way this variable is affecting the biodiversity of the Antarctic food web.
Analyze the change in species richness with or without krill harvesting. Predict how the removal of krill from the Antarctic ecosystem will affect its long-term structure.
Justify the claim that the Antarctic krill is a foundation species, not a keystone species. Provide evidence to support your claim.
Answer:
a) the autotrophs produce their own energy in their system and synthesize surrounding energy, which allows for the flow of energy as they are the primary producers at the bottom of the food web shown in figure 1 who transfer and facilitate their energy when they are consumed by the organisms in higher levels. This facilitation of energy continues where the population of these autotrophs is stable and the cycle of consumption and synthesis of energy from one trophic level to another and there is a diverse amount of energy distributed in the ecosystem. The leopard and Elephant seals have a similar food preference which may cause competition for resources in the ecosystem between the two more than that of the crabeater seal as they rely solely on krill in the ecosystem to survive. If there was more competition for the krill or a decrease in population, their population is sure to suffer as well.
b) The year is independent of the number of species in the data graphed. This variable affects the biodiversity in the food web where we witness the number of species (hundreds) likely to witness an increase over time when krill are harvested and a decrease in the number of species without krill harvesting. This, in turn, may prove that krill is a keystone species crucial in the food web and ecosystem where the antarctic krill population's presence will influence the number of species as well.
c) The changes in species richness with krill harvesting, as per mentioned, will show an increase in species number as the krill's energy is transferred throughout the ecosystem by consumption, as implied in the food web. The changes in species richness with a lack of krill harvesting, or some organisms unable to consume the energy of the krill, was shown to have a decrease in species # over the years. This will affect the long term structure of the ecosystem as the organisms who rely on krill and even those in the trophic levels which rely on species who consume krill will drop dramatically, and the lowering of the number of organisms in a keystone species will cause a decrease in speciation of the ecosystem (possibly quite rapidly due to the dependence we witness on it) as well as a disruption in the energy flow.
d) we can affirm that the krill are in fact not a foundation species, but a keystone species as they show no specific traits of facilitating the populations of the species in the ecosystem, and don't appear to benefit other species in the ways foundation species do (ie. they are autotrophs and cannot provide shelter for other species, but we can also say that they are the sole energy producers for the crabeater seals, which can be a trait of a foundation species)- instead exhibiting the traits of a keystone species as they produce an abundance of energy in the ecosystem and the removal of them (as shown in figure 2), causes a population decrease all around.
Explanation:
ur welcome i just did this myself so pls paraphrase as much as u can also like a bit of an explanation its kinda obvious from the chart that they all rely on the krill and stuff so removing it (or not harvesting or something) would be bad. again pls paraphrase as much as u can and good luck

When crops have two parents, their offspring will all be DIFFERENT.
A True
B False
Explanation: In sexual reproduction one full set of the genes come from each parent. Living things produce offspring of the same species, but in many cases offspring are not identical with each other or with their parents. ... Changes in genes can be caused by environmental conditions, such as radiation and chemicals.
how the cells in your body are different from one another. Look at the different types of cells above, and make a list of how they differ. After you have made your list, consider why they have these differences.
Answer: Different cells have different jobs to do. Each cell has a size and shape that is suited to its job. Cells that do the same job combine together to form body tissue, such as muscle, skin, or bone tissue. Groups of different types of cells make up the organs in your body, such as your heart, liver, or lungs.Differentiation means that one cell performs a different function than another cell, depending on where it is in your body. ... All the cells contain the same genetic material and all of them are from one original cell that started as a fertilized egg, but they look different and act different from one another. Under a microscope, fat cells look like bulbous little spheres. Like other cells in the body, each has a cell membrane and a nucleus, but their bulk is made up of droplets of stored triglycerides, each of which consists of three fatty-acid molecules attached to a single glycerol molecule. Skin cells are specialized to be quickly shed and replaced, and do not have much mitochondria (which helps produce energy). Muscle cells, conversely, have lots of mitochondria because they need energy to produce movement. Unlike many other cells, red blood cells have no nucleus and can easily change shape, helping them fit through the various blood vessels in your body. Unlike most other eukaryotic cells, mature red blood cells don't have nuclei. When they enter the bloodstream for the first time, they eject their nuclei and organelles, so they can carry more hemoglobin, and thus, more oxygen. Each red blood cell has a life span of around 100–120 days. Skin cells are specialized to be quickly shed and replaced, and do not have much mitochondria (which helps produce energy). Muscle cells, conversely, have lots of mitochondria because they need energy to produce movement. brainliest??

Where a disturbance did not completely wipe out all life and nutrients from the environment, secondary succession occurs and homozygous.
Thus, Despite the fact that fire, flooding, and other disturbances can leave a landscape in ruins, drive many animals and plants away, and bring the biological community back to an earlier stage, the habitat is still alive because the soil still contains nutrients and seeds that were sown before the disturbance.
The homozygous genotypes' two alleles are not expressed over one another in incomplete dominance; instead, an intermediate heterozygote is created.
A significant contributing factor to the variety in the traits or properties of an organism is incomplete dominance.
Thus, Where a disturbance did not completely wipe out all life and nutrients from the environment, secondary succession occurs and homozygous.

1- How could you tell whether a given sequence was DNA or mRNA?
2- Was it easier to decode messages written in DNA or in mRNA sequences?
3- Which cellular enzymes or machines are you imitating when you "transcribe" DNA into mRNA?
4- Which cellular enzymes or machines are you imitating when you "translate" mRNA into a chain of amino acids?
5- What else needs to happen in a eukaryotic cell between the processes of transcription and translation?
6- In step 5, how did different mutations affect the amino acid sequence that was encoded?
7- Explain why some single nucleotide mutations affect an amino acid sequence and some single nucleotide mutations do not.
8- Explain why nucleotide insertions and deletions affect the amino acid sequence so profoundly.
9- Why could your secret message include only 20 of the 26 letters of the alphabet?
10- Did you find that it was difficult to work with only these letters?
Answer:
DNA sequences use the nucleotides A, T, G, and C, while mRNA sequences use the nucleotides A, U, G, and C.
It was easier to decode the messages written in mRNA sequences because these sequences could be translated directly into the amino acid sequence.
The cellular enzyme that carries out transcription is RNA polymerase.
The cellular machine that carries out translation is the ribosome, which is composed of both rRNA and ribosomal proteins.
In a eukaryotic cell, an mRNA transcript often has additional untranslated regions and a poly-A tail. A eukaryotic mRNA transcript would need to be transported from the nucleus to the cytoplasm before it could be translated.
Some amino acids are encoded by several codons. If a single nucleotide mutation still encodes for the same amino acid, the resulting amino acid sequence would not be affected. This happens most often with nucleotides in the third position of a codon.
If a single nucleotide mutation changes the amino acid encoded, the resulting amino acid sequence would be affected. This happens most often with nucleotides in the first and second positions of a codon.
Nucleotide insertions and deletions cause frameshift mutations, which change the reading frame of translation and will encode completely different amino acids from that point forward.
There are only 20 canonical amino acids, so the letters B, J, O, U, X, and Z are not used as one-letter codes.
It was a little difficult to not use the letters B, J, O, U, X, and Z at first, but there are messages to write without these six letters.
Explanation:
I don’t understand it, if someone can explain maybe what I have to do and put into each Column or give me the answer either way would help a lot. Thank you.
Answer:
First, describe each type of evidence (eg. Molecular biology is comparing DNA sequences to determine common ancestry). Then provide examples of how those pieces of evidence support the theory of evolution. For example, for one of the comparative anatomy examples, you could say that organisms that contain similar structures most likely diverged from a common ancestor.
I hope this gets you on the right track.

Biotic and abiotic factors affect population density and dispersion. A) Explain the factors that affect a population's density. B) Describe the types of population dispersion, with examples, and the factors that influence them.
Answer:
Water supply, climate, shape of the land, vegetation, soils and availability of natural resources.
Explanation:
Water supply, climate, shape of the land, vegetation, soils and availability of natural resources are the factors that affect population density of an ecosystem. There are three types of population dispersion are uniform dispersion, random dispersion, and clumped dispersion. In uniform dispersion, individuals of a population are more or less evenly distributed for example, allelopathy plants. In random dispersion, individuals are distributed randomly in the ecosystem for example, dandelions plants. Clumped dispersion is when individuals in a population are clustered together for example, oak trees.

Explanation:
because blue is being reflected, all other colors of light are being absorbed by the car.
Answer:
A: Because the blue color wave is being reflected, and all other colors are being absorbed.
Explanation:
Bright colors reflect light. Dark absorb. So white would reflect and black would absorb. Blue is bright, so it would reflect.
In a given year, which would result in the greatest increase in population size?
A. high birth rate, high death rate, high immigration, high emigration
B. high birth rate, zero death rate, high immigration, zero emigration
C. zero birth rate, low death rate, zero immigration, low emigration
D. zero birth rate, zero death rate, low immigration, high emigration
Answer:
B. High birth rate, zero death rate, high immigration, zero emigration
Explanation:
High birth rate would mean more people being born resulting in a higher population. Zero death rate would mean that no one is dying and leaving the population. Immigration means when people come to a foreign country to live there, meaning that the population would grow. Emigration means the opposite of immigration. So that would mean that the people would be leaving your country. Resulting in a lower population. So, B is the correct answer!
