These exchanges are frequently brief. However, there are many instances where two species coexist peacefully for extended periods of time.
What is keystone species?The most numerous species in a community are known as dominant species, and they have a significant impact on the abundance and distribution of other species.
Keystone species, on the other hand, have an impact on communities that greatly outweigh their abundance.
These discussions are typically can be done in many way. Two species can, however, frequently cohabit happily for long periods of time.
Such relationships are known as symbioses ("living together"). Symbiotic relationships can be classified as parasitic, commensal, or mutualistic.

How is most ATP formed during respiration?
Most of the ATP produced by aerobic cellular respiration is made by oxidative phosphorylation
Oxidative phosphorylation is responsible for the majority of the ATP generated by aerobic cellular respiration. Protons are pumped through a membrane to produce a chemiosmotic potential using the energy released. Then, ATP synthase is engaged by this potential to synthesis ATP from ADP and a phosphate group. During aerobic respiration, glucose and oxygen combine to produce ATP, which the cell can utilise. As products, water and carbon dioxide are produced. In the general equation for aerobic cellular respiration, glucose and oxygen combine to create ATP. Oxidative phosphorylation is the biochemical cycle that generates a most net ATP per molecule of glucose. The majority of ATP synthesis takes place during cellular respiration in the mitochondrial matrix, producing about 32 ATP molecules for every glucose molecule.

Compare and contrast the properties of oceanic crust and continental crust
Oceanic crust is generally younger than continental crust, being less than 200 million years old. It is made of basaltic rock, which is denser and more mafic than the granitic rock found in continental crust. Oceanic crust is thinner and more dense than continental crust, with average thickness of about 6 kilometers compared to about 35 kilometers for continental crust. Oceanic crust is also less buoyant and more prone to subduction.
Continental crust is generally thicker and less dense than oceanic crust, and is composed mainly of granitic rock. It is much older than oceanic crust, having formed over billions of years, and is also more buoyant due to its lower density. Continental crust is less prone to subduction and therefore is more likely to form mountains and landforms. It is also much thicker, with an average thickness of about 35 kilometers.

Answer:
B. Can support many different species.
Explanation:
A niche is a position or role that a species plays in its ecological community or ecosystem.
If an ecosystem offers many different niches, this means that many different species can have a role in an ecosystem.
An ecosystem with many different niches will have a greater biodiversity and will also be more stable.
So, the correct answer is B. Can support many different species.
What is the effect of changing the environment on the feeding of birds with different beaks?
The exact traits of each bird's beak and the type of environmental alteration will determine how changing the environment will affect how various beaked birds eat.
For instance, birds with long, narrow beaks designed for digging deeply into blossoms or grabbing insects may have a tougher difficulty locating food if the environment gets drier and food sources become limited.
Their population might decrease as a result of this. Similarly to this, birds with short, broad beaks that are evolved to split apart seeds may have a tougher difficulty locating food if the environment becomes wetter and food sources become limited.
On the other hand, if the environment changes in a way that creates new food sources, birds with beaks adapted to exploit those resources may do well. For example, if a new type of berry becomes available, birds with beaks adapted for eating berries may thrive in that environment.

Plz help! In a density-dependent population, a decrease in which of the following will most likely cause an increase in birthrate?
Carrying capacity
Death rate
Emigration
Immigration
plz don't put link or ill report
In a density-dependent population, a decrease in the death rate will most likely cause an increase in birthrate. It is because a lower death rate means that more individuals are surviving, which can lead to an increase in the number of individuals reproducing, ultimately resulting in a higher birthrate. The correct option is B.
What is a density-dependent population?As we know that a population's birthrate tends to increase if there is a decrease in death rate, which also results in a decrease in carrying capacity.
Also, a density-dependent population is a population where the death rate increases and birthrate decreases with increasing population density, and vice versa. So, a decrease in the death rate of a density-dependent population will most likely cause an increase in the birthrate.
A density-dependent population is a population where the death rate increases and birthrate decreases with increasing population density, and vice versa. A decrease in the death rate of a density-dependent population will most likely cause an increase in the birthrate.

The stomach is the only part of the alimentary canal with three muscular layers. Why does the stomach need three layers of muscle
The stomach is the only part of the alimentary canal with three muscular layers. The stomach need three layers of muscle for digestion through peristalsis.
The stomach is a part of the body that includes the entire abdominal cavity which consists of the digestive tract and accessory organs, the urinary system, and the spleen. There are three layers of muscles in the stomach, namely the outer longitudinal muscles, the middle circular muscles, and the inner oblique muscles which help in peristaltic events.
Peristalsis is a movement in the form of muscle contractions in the digestive tract that pushes and stirs food so that it is digested. Through peristalsis the stomach will break down food and absorb nutrients during the digestive process.
