Niche partitioning facilitate the coexistence of 20 terrestrial bird species investigated in Mohd-Azlan et al dividing resources.

Niche partitioning is a process where species divide resources in order to coexist in a particular habitat. In Mohd-Azlan et al. (2014), niche partitioning facilitated the coexistence of 20 terrestrial bird species by dividing resources. In other words, the birds have found ways to share limited resources such as food and habitat. For example, one bird species may feed on insects while another bird species feed on fruits and seeds.This allows each bird species to access its unique set of resources without direct competition with others.

Another way niche partitioning facilitated coexistence is by using different habitats. For example, some bird species may prefer to inhabit the canopy while others may prefer the understory or ground level. This helps to reduce competition for resources such as nesting sites and food. In conclusion, niche partitioning plays an essential role in facilitating the coexistence of bird species, this is achieved by allowing each species to access resources in a unique way, reducing competition and increasing the likelihood of survival.

Answer:

DNA

Explanation:

The correct answer is the first option. Carrying the genetic code and determining an organism's structure and function are the functions of DNA. It is the hereditary material in almost all other organisms. The information in a DNA is stored as codes that is composed of chemical bases.

The study of cre elements in different species has revealed that there can be significant variation in these elements without causing a significant change in overall gene expression patterns. This is a good example of cryptic genetic variation, which refers to genetic variation that is not readily apparent in an organism's phenotype.

In this case, the variation in cre elements may not affect the expression of the gene in question, but it could still have an impact on other traits or functions that are controlled by the same or related genes. This highlights the importance of considering genetic variation beyond just the genes themselves, and taking into account the regulatory elements that control their expression.

It also underscores the complexity of genetic interactions and the potential for epistasis, or the way in which different genes can interact with each other to produce a particular phenotype. Additionally, competitive binding may play a role in this context, as the variation in cre elements could impact the ability of regulatory proteins to bind to the DNA and control gene expression. Overall, this is a complex and nuanced issue that requires a long answer to fully unpack.

Scientific evidence should be used to investigate the validity of a scientific claim rather than anecdotal evidence because scientific evidence can be empirically tested and verified (option C). This means that scientific evidence is based on systematic observation, experimentation, and analysis, and can be reproduced by other scientists. Anecdotal evidence, on the other hand, represents only one or a few observations about a particular natural phenomenon (option D), and is often based on personal experiences or opinions. As a result, anecdotal evidence is not as reliable as scientific evidence, and is not a valid basis for making scientific claims.

All of the above

What is natural selection?

One method of evolution is natural selection. More environment-adapted organisms are more likely to survive and pass on the genes that contributed to their success. Over time, species change and diverge as a result of this process.

As a result of natural selection, reproductive individuals pass on genetic changes that are advantageous to their progeny's survival. New creatures are created as a result, and they have a higher chance of surviving and reproducing. For instance, giraffes have an advantage over other species because of their long necks, which have evolved to allow them to eat leaves that other species cannot. Longer-necked individuals were able to reproduce and pass on their trait to the next generation because they had access to better food sources. Shorter-necked individuals would be less likely to survive and pass on their genes as a result of having less food availability.

The plant that grows larger has seeds adapted to the environment, which proliferate more readily than seeds from other plants.

One of the two fish species that consume the same food is more adapted and can thus gather more food.

Favorable male lions will be able to compete with other male lions for female mates and will be preferred over them because of their superior adaptation and physical characteristics.

Natural selection, also referred to as "survival of the fittest," is a phenomenon in which organisms that are best adapted to a particular environment are chosen while inferior organisms are weeded out.

In all three cases, biological evolution will take place as a result of selection favoring organisms that are better adapted to their surroundings and capable of competing with other species for survival.

Answer:

A

Explanation:

Because the number of energy is lowering down as it leveled up in pyramid.

Many producers needed to support a smaller number of consumers in food pyramids because a tremendous amount of energy is lost as one moves up trophic levels, as in option A.

The energy available to an ecosystem originates from the sun and is captured by photosynthetic organisms such as plants. These organisms convert light energy into chemical energy through photosynthesis, and this energy is stored in the form of organic molecules like carbohydrates, lipids, and proteins. These organic molecules serve as food for other organisms in the ecosystem, including herbivores, carnivores, and decomposers. However, as energy moves up the food chain from one trophic level to the next, much of it is lost due to inefficiencies in energy transfer and cellular respiration.

I just researched and found this:
"During mitosis the chromosomes are very visible."

I hope that this helped.

Red bone marrow is found in the adult skeleton in all of the following places EXCEPT the Medullary cavity. Red bone marrow is not found in the medullary cavity. Hence, option A is the correct answer.

Red bone marrow is found in several locations within the adult skeleton, including the medullary cavity, metaphysis, and epiphysis. However, it is not typically present in the pelvic crest.

The medullary cavity, also known as the marrow cavity, is the central hollow space within long bones. It contains yellow bone marrow, which is primarily composed of adipose (fat) cells.

In infants, the medullary cavity contains red bone marrow, responsible for hematopoiesis (formation of blood cells). As an individual matures, the red bone marrow gradually converts to yellow bone marrow, with red marrow being mainly confined to specific areas.

The metaphysis is the region of a long bone where the diaphysis (shaft) and epiphysis (ends) meet. It contains red bone marrow, which continues to play a role in hematopoiesis.

The epiphysis refers to the ends of long bones. It contains spongy bone, which houses red bone marrow. This red marrow is responsible for the production of red blood cells, white blood cells, and platelets.

While red bone marrow is present in the medullary cavity, metaphysis, and epiphysis, it is not typically found in the pelvic crest. The pelvic crest consists mainly of compact bone and contains yellow bone marrow.

Overall, red bone marrow is crucial for hematopoiesis and is primarily found in the medullary cavity, metaphysis, and epiphysis of long bones, excluding the pelvic crest.

Most protozoa have a motile, feeding stage known as a(n) "trophozoite," which, in some protozoa, alternates with a resting state known as a(n) "cyst."

Some of the cells in the top layer of the skin produce keratin, a protein that gives skin its strength and flexibility. Normally, these cells move up to the surface of the skin as they start to die so they can be shed. But the cells sometimes move deeper into the skin and multiply, forming a sac. Cyst removal may be performed under general anaesthesia or sedation depending on the size and location. The surgeon will make an incision on the skin above or near the cyst to either drain or remove it.

Diploidy is first re-established following fertilization. So, option A is accurate.

Fertilization is the process in which the male and female gametes (sperm and egg) fuse to form a zygote. During fertilization, the haploid sperm and egg combine their genetic material, resulting in the formation of a diploid zygote. The zygote then undergoes subsequent cell divisions and development, giving rise to an embryo with diploid cells. This marks the re-establishment of diploidy, as the embryo inherits a complete set of chromosomes from both parents. The other options mentioned, such as gastrulation (formation of the three primary germ layers), spermatogenesis (formation of sperm cells), and organogenesis (formation of organs), are important processes in embryonic development but do not directly involve the re-establishment of diploidy.

Complete dominance is the mendelian inheritance pattern, while co-dominance and incomplete dominance are non-mendelian inheritance patterns. Trait 1: Hair length. Trait 2: Hair color. Trait 3: Hair type.

When the dominant allele completely masks the recessive allele, we talk about complete dominance.

This is the case of individuals that are heterozygous for a particular gene and express the dominant trait.

The dominant allele is hiding the expression of the recessive allele.

Codominance refers to a non-mendelian inheritance pattern in which two alleles of the same gane are equally expressed.

There is no dominant or recessive alleles, since non of them hides the expression of the other one in heterozygous individuals.

The phenotype of a heterozygote expresses two alternative variants inherited from each homozygous parent.

Heterozygous individuals express both parental phenotypes, as it is an additive expression of their parents' genes.

Refers to a non-mendelian inheritance pattern in which the heterozygous individual expresses an intermediate phenotype between the dominant and the recessive phenotypes.

Neither of the involved alleles completely dominates over the other one.

We will propose an example of mammal hair,

Trait 1) Simple dominant/recessive inheritance
