What is the difference between food chains and food webs? Food webs show the flow of energy from producers to consumers, and food chains show the flow of energy from consumers to producers. Food chains show a single path of energy in an ecosystem, and food webs show overlapping pathways of energy in that ecosystem. About ten percent of the energy is passed on to the next trophic level in food webs, but in food chains, about ninety percent is passed on to the next trophic level. Heat is lost when energy is passed on to the next trophic level in food chains, but in food webs, heat is not lost when energy is passed on to the next trophic level.
Answer:
Food chains show a single path of energy in an ecosystem, and food webs show overlapping pathways of energy in that ecosystem.
Explanation:
Unlike food chains, food webs show more detailed information about the different animals in an ecosystem and show multiple energy transfers to different animals from the same sources.
By looking at these examples, you will notice a dramatic difference in detail:
Food chains show a single path of energy in an ecosystem, and food webs show overlapping pathways of energy in that ecosystem.
What is food chain?Food chain shows the relationship between organisms by the food they eat.
What is food web?A food web is the natural interconnection of food chains and a graphical representation of what-eats-what in an ecological community.
Difference between food chain and food webFood webs show interconnection of food chains about the different animals in an ecosystem and different energy transfer processes.

Chemical energy can be converted into mechanical energy by the arrangement of batteries, wire, and fan blades turning. The chemical energy from the movement of ions in the wire causes the movement of fan blades and this turning is a form of mechanical energy.
In a combustion engine, chemical energy is first converted to heat energy that causes expansion of a fluid which results into motion. In contrast, the motor proteins are the molecules which can convert the chemical energy present in the molecules released from adenosine triphosphate (ATP) hydrolysis directly into useful mechanical work.
Therefore, the correct option is C.

What do plants produce when they make their own food?
Answer:
Plants are autotrophs, which means they produce their own food. They use the process of photosynthesis to transform water, sunlight, and carbon dioxide into oxygen, and simple sugars that the plant uses as fuel. These primary producers form the base of an ecosystem and fuel the next trophic levels.
Explanation:
Answer:
Their roots take up water and minerals from the ground and their leaves absorb a gas called carbon dioxide (CO2) from the air. They convert these ingredients into food by using energy from sunlight. This process is called photosynthesis, which means ‘making out of light’. The foods are called glucose and starch
Meiosis occurs in a series of different phases and creates genetically unique reproductive cells.
Which process helps make meiotic cells genetically different and occurs during prophase I, but not during prophase II?
fertilization
independent assortment
crossing over
chromosome replication
Answer:
Meiosis occurs in a series of different phases and creates genetically unique reproductive cells. The process which helps make meiotic cells genetically different and occurs during prophase I, but not during prophase II, is crossing over (C). Crossing over is the exchange of genetic material between two homogenous chromosomes. It is one of the final phases of prophase I. This process is called synapsis. It occurs when the matching regions on the matching chromosomes break and then reconnect to the other chromosome .
The process that helps to make meiotic cells genetically different and occurs during prophase I is called crossing over.
Crossing over, also known as recombination, is the interchange of genetic material between non-sister chromatids of homologous chromosomes.This process (crossing over) occurs in Meiosis I, specifically during Prophase I.Crossing over during Prophase I and the independent assortment of homologous chromosomes during Metaphase I represent meiotic processes that help to increase genetic variation in gamete (sex) cells.In conclusion, the process that helps to make meiotic cells genetically different and occurs during prophase I is called crossing over.

What properties of dna makes it possible for a probe to find a single-stranded dna target gene?
A. Alleles are in pairs
B. Probes are dominant over genes
C. Chromosomes come in pairs
D. A DNA molecule has two paired strands
DNA has two strands. If the sequence of nucleotides of one strand was known, is it possible to use that information to determine the sequence of the second strand? Explain your reasoning for your response using an example DNA sequence. and this is for biomedical science.
Answer:
Yes
Explanation:
DNA, which is the genetic material, is a double-stranded molecule i.e. possess two strands. Each strand is made up of a sequence of nucleotide base, which are complementary to one another. The complementary base pairing rule as proposed by Chargaff states that Adenine (A) base will always hydrogen pair with Thymine (T) base while Guanine base (G) will always pair with Cytosine (C) i.e. A-T, G-C.
For example, If the sequence of nucleotides of one strand was CTAGCGGATC, the sequence of nucleotide of the other strand will be GATCGCCTAG. Hence, based on this question, the information of the sequence of base on one strand can be used to determine the sequence of the second strand.
help asap!! "Watermelon snow" in Antarctica is caused by a species of photosynthetic green algae that thrives in subzero temperatures (Chlamydomonas nivalis). These algae are also found in high altitude in year-round snowfields. In both locations, UV light levels tend to be high. The reddish-pink color of these algae is due to the presence of carotenoid pigments, which absorb blue light while reflecting red light. Those pigments protect the chloroplast from ultraviolet radiation, as well as absorbing heat, which provides the algae with liquid water as the snow melts around it. This molecular variation in plants illustrates
A) relative fitness because the molecular adaptations in chlorophyll pigments have passed to the next generation
B) innate variability because plants have evolved molecular differences to an environmental stimuli
C) unselective adaptation because plants have evolved molecular differences to adapt to different wavelengths of light
D) inclusive fitness because differences in chlorophyll pigments increase the proliferation of beneficial traits in the population
Answer:
A
Explanation:
This molecular variation in plants illustrates relative fitness because the molecular adaptations in chlorophyll pigments have passed to the next generation. The correct option is A.
What is relative fitness?Absolute fitness is normalized relative fitness. It is a biological fitness measure that compares the reproductive rate of a genotype or phenotype to the maximum reproductive rate of other genotypes or phenotypes in a given population.
The contribution of an individual to the next generation's gene pool in comparison to the contributions of other individuals.
It is important to remember that natural selection acts both directly on the phenotype and indirectly on the genotype that controls that phenotype.
Because the molecular adaptations in chlorophyll pigments have been passed down to the next generation, this molecular variation in plants demonstrates relative fitness.
Thus, the correct option is A.

When an organelle stops
functioning properly, which of
the following occurs?
Answer:
B.
Explanation:
When an organelle stops functioning properly, what is most likely to occur is that such organelles would be removed from the cell by lysosomes. the correct option, in this case, would be B.
Lysosomes are small spherical molecules with single membranes. The organelle primarily functions in the digestion of cell macromolecules and dead organelles.
Thus, the content of the lysosome is usually filled with digestive enzymes such as protease, lipase, nuclease, etc.
Lysosomes are protected from their own enzymes because of the membrane surrounding them. The contents are not allowed to spill out.

Identify whether each item is a reactant or a product of cellular respiration
Answer:
Glucose is a reactant of cellular respiration.
Carbon dioxide and water are both products if cellular respiration.
Note: The question is incomplete. The complete question is given below:
Identify whether each item is a reactant or a product of cellular respiration. glucose carbon dioxide (co2) water (h2o)
Explanation:
Cellular respiration is the process by which glucose is broken down by the cells to produce the energy molecules, ATP.
The various reaction steps of cellular respiration include glycolysis- where glucose is broken down into two molecules of pyruvate, the citric acid cycle- where two acetylCoA molecules produced from the oxidation of pyruvate are converted to carbon dioxide molecules, and finally the electron transport chain- where the electron-donors NADH and FADH2 produced in the citric acid cycle donate their electrons to oxygen to produce water molecules.
The overall chemical reaction for cellular respiration is represented as follows:
C6H12O6 + 6O2 → 6CO2 + 6H2O
1 molecule of glucose reacts with six molecules of oxygen to produce six molecules of carbon dioxide and six molecules of water.
Therefore, glucose is a reactant while carbon dioxide and water are both products of cellular respiration.
