Answer:

it would be 50% heterozygous and 50% homozygous

Explanation:

this isnt copying, the comment was me too!

Answer:

As a cell increases in size, it usually does not make extra copies of DNA. If a cell became too large, an "information crisis" would occur. The cell has more trouble moving enough nutrients and wastes across the cell membrane.

Explanation:

During interphase the cell cycle, the cell grows and replicates both its organelles and its chromosomes.

Cell organelles are the sub-cellular components that work in order to keep the cell functional and alive. These reside in the cytoplasm of the cell. The various cell organelles are nucleus, mitochondria, lysosomes, chloroplast, endoplasmic reticulum, etc.

Chromosomes are the most compact form of genetic material. It is comprised of the DNA and histone proteins. Each chromosome consists of two sister chromatids joined together at the centromere. This is the form of DNA which is inherited from parents to offspring during the cell division.

The post darwinian view of the world included all of these.

Famous philosophers and biological scientists are believed to have suggested and declared post-Darwinian beliefs as instructional theories after the Darwinian Theory of Evolution was presented. Charles Darwin (1809–1882), an English naturalist, and others developed the Darwinism theory of biological evolution, which holds that all species of organisms arise and develop through the natural selection of minute, inherited variations that improve the individual's capacity for competition, survival, and reproduction.

Later, the term "Darwinism" was used to describe the particular ideas of natural selection, the Weismann barrier, or the core tenet of molecular biology. Although the phrase only ever relates to biological evolution, creationists have appropriated it to mean other things that are not biological evolution, such as the genesis of life or cosmic evolution.

Answer:

I-1 genotype = AA or Aa

I-2 genotype = aa

Explanation:

The trait in question is autosomal and dominant. Let us assume that the trait is represented by the allele A, the alternative form would be a.

I-1 individual is affected for the disease, hence he is either true-breeding AA or heterozygous Aa.

I-2 individual is not affected for the disease, hence, she can only be aa. For an autosomal dominant trait, an individual is either affected or free from the trait. There is no chance of being a carrier. Heterozygous individuals are affected for the disease.

Therefore;

I-1 genotype = AA or Aa

I-2 genotype = aa

Wind blowing across the body surface would increase the rate of heat exchange between an animal and its environment.

Wind blowing across the body surface would increase the rate of heat exchange between an animal and its environment. Wind can carry heat away from the body through convection, which enhances the transfer of heat from the body surface to the surrounding air. This can help to cool down the animal if it is in a warm environment or if it has generated excess heat through metabolic processes.

Vasoconstriction, on the other hand, is the narrowing of blood vessels, which reduces the flow of blood to the skin and decreases heat loss. Countercurrent heat exchangers are specialized structures found in some animals, such as marine mammals and birds, that help to reduce heat loss by transferring heat from warm arterial blood to cooler venous blood before it reaches the extremities. Blubber or fat layer acts as an insulating layer, reducing the rate of heat exchange between the animal's body and the environment, which can be beneficial in cold environments by helping to retain body heat.

The statement "in monogamous groups, the males and females may have more than one mating partner" is false.

A mating system known as monogamy is one in which a person only ever has one mating partner at a time. Males and females in monogamous societies create exclusive pair bonds and exclusively mate with one another. This indicates that in monogamous groups, neither males nor females are simultaneously mated with more than one partner.

Therefore, The adage "in monogamous groups, the males and females may have more than one mating partner" is untrue.

The blue-gray precipitate seen in reticulocytes stained with supravital stains like methylene blue is made up of ribosomes.

The blue-gray precipitate seen in reticulocytes stained with supravital stains like methylene blue is made up of ribosomes, which are the remnants of the reticulocyte's protein synthesis machinery. Reticulocytes are young red blood cells that have just been released from the bone marrow into the bloodstream and are still in the process of maturing into fully functional red blood cells.

During this process, the reticulocytes synthesize hemoglobin, which is the protein that carries oxygen in red blood cells. The ribosomes in the reticulocytes help to synthesize the hemoglobin, but are eventually broken down as the reticulocyte matures into a fully functional red blood cell.

What is Mendel's law ?

The laws of inheritance in organisms which found by Gregor Johann Mendel is called by Mendel's law.

This law consists of 2 laws, among others:

1. The law of segregation is the law which states that in the formation of gamete cells, the parent cells (alleles) separate so that each gamete cell has genes from the parent cell.

Example : A white horse (PP) is mated with a brown horse (pp), so the phenotypic ratio of the two is as follows:

P1 : PP v pp

F1 : Pp

P2 : Pp v Pp

F2 : PP, Pp, Pp, pp

The ratio between white and brown horses is 3:1

2. The law of independent assortation is a law which states that in the formation of gamete cells, stem cells that have more than one different nature do not affect each other. Example : Plants with blue flowers and small leaves (BBKK) are mated with yellow broadleaf plants (bbkk), so the phenotypic ratio of the two is as follows:

P1 : BBKK v bbkk

F1 : BbKk

P2 : BbKk v BbKk

F2 : BBKK, BBKk, BbKK, BbKk , BBKk BBkk BbKk Bbkk, BbKK BbKk bbKK bbKk, BbKk Bbkk bbKk bbkk

So the ratio of F2 is 9:3:3:1

Explanation:

food web:

a system of interlocking and interdependent food chains.

Answer:

food web

Explanation:

food web consists of all the food chains in a single ecosystem. Each living thing in an ecosystem is part of multiple food chains.

Heterotrophs must obtain their energy from other living things, whereas autotrophs can harness the sun's energy.

Organisms can be categorized into two main groups: autotrophs and heterotrophs, based on how they receive energy and nutrients. Because they can manufacture their own food from raw materials and energy, autotrophs are referred to as producers. Numerous varieties of bacteria, plants, and algae are examples.

When an organism uses other plants or animals for food and energy, it is referred to as a heterotroph. Heterotrophs are a group of organisms that are found in the second and third tiers of a food chain, and their name derives from the Greek terms hetero, which means "other," and troponin. Each food chain is composed of three trophic levels, which describe an organism's role in an ecosystem. Autotrophs, which include plants and algae, make up the first trophic level of the food chain. Herbivores—animals that eat plants—dwell on the second level. Omnivores and carnivores (animals that eat meat) live on the third level (animals that consume both plants and meat). Primary consumers (herbivores) and secondary consumers (carnivores and omnivores) are both heterotrophs, which means "nutrition," whereas primary producers are autotrophs.
