How would the food web be impacted if the zooplankton population
decreased?
Answer:
Plankton are also very important because they help make the air we breathe. If all the plankton disappeared it would increase the levels of carbon in our air, which would not only accelerate climate change, but also make it difficult for humans to breathe. It would impact the food web in ways that could make it collapes
Explanation:
Through their birth, growth, death and decay, plankton create global carbon. Half of the oxygen bubbling out of zooplankton is floating in the seas. Plankton are the principal producers of atmospheric oxygen.
Decommissioned oil rigs are sometimes converted to artificial reefs in the Gulf of Mexico. What is the likely impact to the ecosystem by creating artificial reefs around these retired oil rigs?
a
The large fish population will increase, but the small fish population will decrease.
b
Biodiversity is increased throughout the ecosystem.
c
Biodiversity remains the same because organisms do not like man-made structures
d
Invasive species of fish move into the ecosystem because there are no natural predators.
Answer:
B
Explanation:
B
The likely impact on the ecosystem by creating artificial reefs is that biodiversity would be increased throughout the ecosystem (Option B).
What is biodiversity?The term biodiversity makes reference to all types of forms of life (organisms) present in a given ecosystem.
Biodiversity can also be used to explain the genetic and phenotypic variation in a population.The loss of biodiversity may have drastic consequences on the whole ecosystem.In conclusion, the likely impact on the ecosystem by creating artificial reefs is that biodiversity would be increased throughout the ecosystem (Option B).

The relative difference in charge across a plasma membrane is the ____________ in an inactive excitable cell. A ____________ is used to measure the voltage difference across the plasma membrane. This is done by placing one microelectrode into the ____________ and the other microelectrode outside the neuron into the ____________ . The RMP has a value that is typically ____________ millivolts. More positive ions reside ____________ a neuron than ____________ a neuron when it is at rest.
Answer:
Resting membrane potential; voltmeter; neuron; interstitial fluid; -70; outside; inside.
Explanation:
A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature.
A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.
In a cell, the "workers" that perform various functions or tasks for the survival of the living organism are referred to as organelles. Some examples of cell organelles with their respective functions in all living organisms such as trees, birds, and bacteria include; nucleus, cytoplasm, cell membrane, golgi apparatus, mitochondria, lysosomes, ribosomes, chromosomes, endoplasmic reticulum, vesicles, etc.
The relative difference in charge across a plasma membrane is the resting membrane potential in an inactive excitable cell.

QUESTION: what’s the function shared by roots stems but NOT by leaves 1. Food productions 2. Structural support 3. Reproduction
Answer:
structural support is the function
The function shared by roots and stems but NOT by leaves is structural support.
What is the function of roots?
Roots are essential plant organs that anchor the plant in the soil and absorb water and nutrients from it. They also store food and help in the synthesis of growth-promoting hormones.
Roots play a vital role in the overall health and growth of the plant, and their efficiency in nutrient and water uptake determines the plant's ability to survive and thrive in its environment. Additionally, roots can form beneficial associations with fungi, such as mycorrhizae, which can aid in nutrient uptake and contribute to plant growth and health.

Explanation:
Analisa and Mateo, two research anthropologists interested in deciphering the relatedness between four extinct primates, were studying the similarities and differences among a number of measurements of the complex structures of the jaw fragments they collected, as well as making many other morphological contrasts between other fossilized bones from dozens of collected specimens. In the lab, they noticed the lengths of the bones of the leg, particularly the femur, tibia, and fibula, were very different in all the specimens, whereas the jaw structures were nearly identical among the specimens. What should they tentatively conclude based on this evidence
The group of choices associated with the question is as follows:
A)The four primates likely share a close common ancestor or could potentially be the same species based upon the jaw measurements.
B)The hominids with the most closely matching leg bone measurements are likely more closely related than the others, due to the importance of locomotion as an evolutionary adaptation.
C)The femur measurements are not important.
D)Because the measurements of the leg bones vary widely, it is probable that the four species are from different genera.
Answer:
The correct answer is - The four primates likely share a close common ancestor or could potentially be the same species based upon the jaw measurements.
Explanation:
On the basis of the research, it is found that the four primates have similar jaw structure and measurement and have a distinct length of bones of the leg.
The given research and founding suggests that all four primates most likely share a close common ancestor or diverge from the same species based on her jaw measurements.

1. What is special about the hand of humans?
2. The design of the human hand is an adaptation. How does our hand's design allow us to do so many tasks such as writing, texting, and tying shoes?
Answer:
What makes human hands unique? ... This long thumb and its ability to easily touch the other fingers allow humans to firmly grasp and manipulate objects of many different shapes. The human hand can grip with strength and with fine control, so it can throw a baseball or sign a name on the dotted line.
Humans, as well as monkeys, gorillas, and other primates, have a hand that can grip and grasp objects because they have an opposable thumb. The earliest primates were arboreal (they climbed trees), and so having grasping hands was an advantage in this environment. Human thumbs modified their ancestors’ opposable thumbs, making them more mobile and thus even more opposable.

Two short-haired guinea pigs are mated several times. Out of 100 offspring, 25 of them have long hair. What are the probable genotypes of the parents? Show the Punnett Square to prove it.
Answer:
Ss (male) × Ss (female)
Explanation:
This question involves a single gene coding for hair length in guinea pigs. Based on the information in this question, the allele for short hair (S) is dominant over the allele for long hair (s). This means that a guinea pig will only be phenotypically long-haired if the genotype is "ss".
According to this question, Two short-haired guinea pigs are mated several times. Out of the 100 offsprings produced by this cross, 25 of them have long hair (recessive). This means that the phenotypic ratio of this cross is 3 short hair : 1 long hair i.e. 100 - 25 = 75 short hair. 75/25 = 3/1 = 3:1
To produce this phenotypic ratio, the parents must both be heterozygous (Ss) for the hair length gene.

Describe the order of succession for the regrowth of
the fire destroyed forest.
Explanation:
Primary succession is one of two types of biological and ecological succession of plant life, occurring in an environment in which new substrate devoid of vegetation and other organisms usually lacking soil, such as a lava flow or area left from retreated glacier, is deposited.[1] In other words, it is the gradual growth of an ecosystem over a longer period of time.[2][3]
Primary succession occurring over time. The soil depths increase with respect to the increase in decomposition of organic matter. and there is a gradual increase of species diversity in the ecosystem. The labels I-VII represent the different stages of primary succession. I-bare rocks, II-pioneers (mosses, lichen, algae, fungi), III-annual herbaceous plants, IV-perennial herbaceous plants and grasses, V-shrubs, VI-shade intolerant trees, VII-shade tolerant trees.
Primary succession on Rangitoto Island
In contrast, secondary succession occurs on substrate that previously supported vegetation before an ecological disturbance from smaller things like floods, hurricanes, tornadoes, and fires which destroyed the plant life.[4]
