Identify the most recent common ancestor of the following pairs: species 19 and species1; species 28 and species 14; species 22 and species 2.
Answer:
Species 28 and 14
Explanation:
Take the species that has the greater number, and the subtract it with the number of the other species. Then you would be able to see how many new species evolved between them.

neurotransmitters cause a response in the postsynaptic neuron by
Answer: Stimulation of excitatory receptors by neurotransmitter binding causes depolarization of the postsynaptic plasma membrane, promoting generation of an action potential. Conversely, stimulation of inhibitory receptors causes hyperpolarization of the postsynaptic membrane, repressing generation of an action potential.

Answer:
The answer is True!
Explanation:
Red eye color in fruit flies is dominant over white eyes. If eye color is X-linked,
what results do you expect to see if you cross a true-breeding red-eyed female
(genotype: XW+/XW+) with true-breeding a white-eyed male (XW/Y)?
Select one:
a. All offspring will have white eyes.
b. 100% of females will have red eyes, 0% of males will have red eyes.
c. All offspring will have red eyes.
d. 50% of females will have red eyes, 50% of males will have red eyes.
Answer:
C All fruit flies have red eyes.
Explanation:
See the image below
Since R (red) is dominant over r (white), then every fruit fly with R will have red eyes.
(The genotypic ratio indicate that 2 of the 4 boxes are XRXr and the other 2 boxes are XRY. While the phenotypic ratio indicate that 2 of the 4 boxes are red eye females and the other two boxes are red eye males. And since there's only 2 females and 2 males in total, everyone have red eyes.)
what is heat on earth caused by?
Answer:
There are three main sources of heat in the deep earth: (1) heat from when the planet formed and accreted, which has not yet been lost; (2) frictional heating, caused by denser core material sinking to the center of the planet; and (3) heat from the decay of radioactive elements

Infants do best with:
A variety of caregivers
A primary caregiver
Infants do not thrive in childcare
A large group setting Two caregivers
Answer: A primary caregiver
Explanation:
It is very important that an infant have a primary caregiver as they develop in their early childhood. This is because it will be easier for the infant to bond with the person and begin to trust them for their safety.
This will ensure that their brains develop much more effectively especially in the areas responsible for emotional and social interaction and attachment.

Explanation:
Explain the difference between renewable and nonrenewable resources and give an example of each.
Answer:
Nonrenewable Resources take longer to be replenished, reneweable resources are easily replenished and easily accessible.
Explanation:
If something is Nonrenewable; for example fossil fuels like coal, oil, and natural gas, then that means that the organic matter is limited and not going to grow or be created easily on Earth.
Renewable Resources are usually classified into five categories; Hydro, Solar, Wind, Biomass, and Geothermal. All of these resources are easily accesible and can be used as a natural energy source.
Hope this helped :)
Answer:
Nonrenewable Resources take longer to be replenished, reneweable resources are easily replenished and easily accessible.

Why does rifting might matter to people that aren't geologists? pls help me ASAP this is due in half a hour
Answer:
Rifting is defined as the splitting apart of a single tectonic plate into two or more tectonic plates separated by divergent plate boundaries. The rifting of a continental tectonic plate creates normal fault valleys, small tilted block mountains, and volcanism.
Explanation:
It causes valleys and stuff so the earth would rip kind of, but for geologist it is good beacsue they can explore that stuff, and find things they were looking for but got burried underneath so many things like rock, and dirt.
Why did the removal of wolves affect the entire Yellowstone ecosystem?
A. The ecosystem has a complicated series of interactions.
B. Wolves were the only predators in the ecosystem.
c. The wolves were the only producers in the ecosystem.
D. The wolves ate most of the species in the ecosystem.
Answer:
A
Explanation:
Since Wolves were one of the main predators (not the ONLY one) prey started to over populate causing the vegetation population to decrease. Since the vegetation decreases so does the number of prey then as well as the number of predators.
The removal of wolves from the Yellowstone ecosystem had a profound effect on the entire system. Wolves are apex predators, meaning they are at the top of the food chain, and their presence has a far-reaching impact on all other species in the environment.
What role do they play in balance of ecosystem ?Wolves, along with other predators, play an important role in maintaining the balance of the ecosystem by controlling the population of other species.
A. The ecosystem has a complicated series of interactions. The Yellowstone ecosystem is a complex web of interactions between species, and the presence of wolves is an integral part of this system.
Wolves are keystone predators, meaning that they have a disproportionately large impact on the environment relative to their numbers. Wolves hunt large game animals, such as elk and bison, which helps to keep their populations in check and prevent overgrazing.
This, in turn, helps to maintain the balance of the ecosystem and protect the health of the plants and other animals that depend on the vegetation for food. B. Wolves were the only predators in the ecosystem. When wolves were removed from the Yellowstone ecosystem, their role as a predator was not filled by any other species
. This had a dramatic effect on the balance of the ecosystem, as the large game animals such as elk and bison were no longer kept in check by predators. This led to an overpopulation of these species, which caused them to overgraze the vegetation and disrupt the delicate balance of the ecosystem. C.
The wolves were the only producers in the ecosystem. Wolves are also important producers in the ecosystem. As they hunt and feed on large game animals, they provide a source of nutrients for other species. This is especially important in the winter months, when other food sources may be scarce.
The presence of wolves helps to ensure that other species in the ecosystem have access to food and nutrients, which helps to maintain the balance of the ecosystem. D. The wolves ate most of the species in the ecosystem. This is not accurate.
Wolves do not eat most of the species in the ecosystem, but rather they help to control the populations of certain species, such as elk and bison, which helps to maintain the balance of the ecosystem.
Therefore, The presence of wolves also helps to ensure that other species have access to food and nutrients, which helps to maintain the health of the entire ecosystem.

Which energy conversion occurs in the cells of algae, such as the kelp shown
in the photograph?
A. Potential energy → Kinetic energy
O B. Light energy - Chemical energy
C. Chemical energy → Light energy
D. Potential energy → Nuclear energy
Answer: B. Light energy - Chemical energy
Explanation:
Algae is a food producer because it uses the process of photosynthesis to synthesize the organic glucose from the inorganic molecules of carbon dioxide and water.
It does this in the presence of sunlight which gives energy to the reaction by being converted from light energy to chemical energy in the cells of the algae.
