Answer: The two species coexist successfully because each occupies a different niche.

Explanation:

Two species of birds that are closely related to each other tend to live on the same tree because they occupy different niche. Two different species coexist as they have different food preferences.

Niche of the species can be defined as the the contribution of the species in the ecosystem and different organism contributes differently in the ecosystem.

There are many factors such as distribution, temporal and spatial distribution which can be different for both of the species.

So, the difference in the niche of the species enables them to coexists.

Answer:

It is possible since a receptor can activate different signaling pathways in different cell types  

Explanation:

In a cell, a receptor bind to a specific ligand to activate a signaling pathway, while the same receptor may bind either with the same or another ligand in another cell type and thus activate another signaling pathway

One receptor can induce different phenotypes in different cell types as a

result of the ability to activate different signaling pathways in different cell

types  in the body.

Receptors are compounds which have a particular substrate it binds to which are known as ligands when information is to be conducted from one point to another.

Cells have receptor which bind to a specific ligand in order to activate a

signaling pathway. The receptor however can bind to a ligand found in

another type of cell which explains how it's able to induce different

phenotypes in different cells.

Answer:

Genetic drift

Explanation:

Genetic drift can also be referred to as allelic drift, it refers to the variation in allelic frequencies within a particular population over a period of time. It can also be referred to as the random fluctuations in the number of genotypes within a population. Genetic drift is not influenced by the environment and is usually more pronounced in a small population of organisms.

For example, a population of birds can consist of green feathers and blue feathers with the green feathers as the dominant allele, but as a result of random fluctuations, the offspring may all be with green feathers and hence could eliminate or reduce the allele responsible for blue feathers over time.

Answer: a. endoderm-bone

Explanation: In the context of embryonic development, bone tissue may arise from several precursor cell populations, such as the neural crest (some facial bones), lateral mesoderm (bones of the limbs, among others), and paraxial mesoderm (vertebrae and part of the skull). There is no evidence to suggest that any of the bony structures is derived from the endoderm germ layer.

The difference between a multicellular organism and a colonial organism is that the individual organisms that form a colony or biofilm can, if separated, survive on their own, while cells from a multicellular organism (e.g., liver cells) cannot.

Explanation:

hope this helps

please like and Mark as brainliest

Individual organisms from a colony or biofilm can survive on their own if they are separated, whereas cells from a multicellular organism cannot. This is the distinction between a multicellular organism and a colonial organism.

A colony in biology is made up of two or more conspecific individuals that coexist or are related to one another.

There are advantages for both parties to this connection, such as improved defense or the capacity to assault larger prey.

Multiple independent unicellular creatures make up a colony. All multicellular organisms are interdependent.

Cells from a multicellular organism cannot survive on their own if they are separated, in contrast to individual organisms from a colony or biofilm. This distinguishes a colony organism from a multicellular creature.

Thus, this is the difference between a colonial organism and a multicellular organism.

Explanation:

a somewhat regular progression of species replacement is called succession consists of a community and all the physical aspects of its habitat such as the soil water and weather. Ecosystem.

Ecological succession is the term used to describe a regular progression of species replacement in an ecosystem, whereby increasingly complex species adapt and replace the existing species until a stable climax community is established.

A regular progression of species replacement is called ecological succession. This is a process observed in ecology where ecosystems change and develop over time. At the start of this process, a relatively barren area may only support simple life forms such as algae or bacteria. As time progresses, increasingly complex species adapt to the new conditions and replace the existing species. This continues until a stable community is established, often referred to as a climax community. An example of this could be a new volcanic island that initially has no life, but over hundreds of years, becomes a complex forest ecosystem.

Final answer:

When organisms die, the nitrogen in their bodies is released through decomposition and can be recycled back into the environment through various processes.

Explanation:

When organisms die, the nitrogen in their bodies is released through the process of decomposition. Decomposers, such as bacteria and fungi, break down the organic compounds in dead organisms and release nitrogen in the form of ammonium ions into the soil. This ammonium can then be absorbed by plant roots or converted into nitrates by nitrifying bacteria in the soil. Ultimately, this nitrogen can be recycled back into the atmosphere through the process of denitrification, where bacteria convert nitrates back into nitrogen gas.

Explanation:

which agent of erosion most likely moves sediments in a send dune.

Glaciers

The agent of erosion most likely moves sediments in a send dune is wind. Thus, option A is correct.

Wind has been defined as the geological phase through which a landform or land mass has been attached to sediments, soil, and rocks.This occurs when the wind slows down or some barrier, like a rock or a clump of grass, traps the sediment of wind-blown sands.

Wind deposition is an agent of erosion which most likely moves sediments in a sand dune. This increases in pace as the wind passes up and over the barrier. It takes the grains of sand up the gently sloping, salting upwind side of the dune.

Natural sand dunes usually start as windblown sand that accumulates in a sheltered area behind some type of obstacle such as piles of seaweed and a hill of sand made up of wind on the coast or in a desert and it is because of erosion by wind strong winds blow across the loose sand on the surface of the earth including sands found in deserts.

Therefore, The agent of erosion most likely moves sediments in a send dune is wind. Thus, option A is correct.

In the moss life cycle, diploid cells within a sporangium undergo meiosis to produce haploid spores. Therefore, option c is correct

 - Sporangium: The sporangium is a structure in mosses that contains diploid cells.

 - Meiosis: Within the sporangium, diploid cells undergo meiosis, a type of cell division that reduces the chromosome number by half, resulting in the formation of haploid spores.

 - Haploid Spores: These haploid spores are released from the sporangium and dispersed by wind or water, eventually germinating into haploid gametophytes, the next stage in the moss life cycle.

 - Alternation of Generations: Mosses exhibit alternation of generations, where the haploid gametophyte generation alternates with the diploid sporophyte generation.

 - Importance: This process ensures genetic diversity in moss populations by shuffling genetic material through meiosis, ultimately contributing to the survival and adaptation of mosses in diverse environments.

aquaporins

Explanation:

aquaporins are channel proteins that allow water to flow through a membrane. The rate of osmosis depends on ratio of intracellular to extracellular concentration as well as the presence of aquaporins in the cell membrane

The rate of osmosis across a cell membrane depends on the following :

Osmosis is the diffusion of water or liquid solvents through a semi-permeable membrane.   the semi-permeable membrane prevents the passage of solutes during osmosis.

The rate of osmosis depends on the concentration of solute present in the solvent, inside and outside the cell.  while the presence of aquaporins also improves the rate of osmosis as it aids the flow of the solvent through the semi-permeable membrane.     while

we can conclude that the intercellular, extracellular solute concentration and the presence of aquaporins have significant effect on the rate of osmosis across a cell membrane.

Explanation:

The green pigment chlorophyll is located within the thylakoid membrane, and the space between the thylakoid and the chloroplast membranes is called the stroma

Chlorophyll molecules, which are key in photosynthesis, are located in the thylakoid membrane of the chloroplast. They absorb light to initiate the light-dependent reactions of photosynthesis.

Chlorophyll molecules are located in the thylakoid membrane of the chloroplast. The thylakoid membrane is a system of interconnected discs where the light-dependent reactions of photosynthesis occur. These reactions convert light energy into chemical energy, specifically ATP and NADPH, which are then used in the Calvin cycle in the stroma of the chloroplast to create glucose. The chlorophyll in the thylakoid membrane absorbs light and uses that energy to initiate photosynthesis.
