Which statement describes meiosis?

The chemical equation demonstrates that mass is neither created nor destroyed and it obeys law of conservation of mass as mass is restored in the products .

According to law of conservation of mass, it is evident that mass is neither created nor destroyed rather it is restored at the end of a chemical reaction .

Law of conservation of mass and energy are related as mass and energy are directly proportional which is indicated by the equation E=mc².Concept of conservation of mass is widely used in field of chemistry, fluid dynamics.

Law needs to be modified in accordance with laws of quantum mechanics under the principle of mass and energy equivalence.This law was proposed by Antoine Lavoisier in the year 1789.

Codominance is a phenomenon in genetics where two alleles (different forms of the same gene) express themselves equally in an organism. As a result, characteristics linked to each allele are shown at the same time.

One common characteristic of people that you can't really see just by looking at them, but that many people are aware of, is their blood type. One A allele and one B allele are present in individuals with the blood type AB. Their blood type is AB because both alleles are expressed simultaneously.

What is protein?
Large biomolecules as well as macromolecules known as proteins are made up of one or more extended chains of amino acid residues. Among the many tasks that proteins carry out in living things are catalysing metabolic processes, replicating DNA, reacting to stimuli, giving cells and organisms structure, and moving molecules from one place to another. The primary way that proteins differ from one another is in the order of their amino acids, which is determined by the nucleotide sequence of their genes and typically causes a protein to fold into a particular 3D structure that controls its activity.

A polypeptide is an ordered sequence of amino acid residues. At least one lengthy polypeptide is present in every protein. Less than 20–30 residue polypeptides are frequently referred to as peptides and are rarely thought of as proteins.

In the process of conversion of dihydroxyacetone phosphate step in glycolysis, glucose-6-phosphate is needed to generate dihydroxyacetone phosphate. Thus, the correct option is C.

Glycolysis is the process of formation of pyruvate from the catabolism of glucose molecule. This process produces ATP, NADP, and FADH₂ molecules.

Dihydroxyacetone phosphate (DHAP) reaction step involves the conversion of DHAP to glyceradehyde-3-phosphate (G3P) by the enzyme triose phosphate isomerase. This enzyme catalyzes isomerization of a three-carbon sugar into another three-carbon sugar (G3P).

Dihydroxyacetone phosphate lies in the glycolysis pathway, and is one of the two products formed by the breakdown of fructose-1,6-bisphosphate, along with glyceraldehyde-3-phosphate. It is rapidly and reversibly isomerized to glyceraldehyde-3-phosphate.

Therefore, the correct option is C.

The likely impact is that the species A's population will decrease due to limited space in the ecosystem

An ecosystem is the community of all living organisms and their interactions with non-living organisms. They function as the system as a whole. Itrefers to the system's biotic and abiotic components. The ecosystem's abiotic factors are light, temperature, and water. Plants, animals, and bacteria are the biotic components of an ecosystem.

A lack of food and space are two limiting factors. Because of competition for resources such as food and space, population growth slows and levels off. The carrying capacity (K) is the maximum population size that can be supported in a given area without causing habitat destruction.

2. 5, circle AUG, GGC, UAC, AUC, UGA

3. There will be 5 amino acids because we have 5 codons.

Explanation:

For this first question, we will need a codon chart, such as the picture I put up.

To find the amino acids with this, we will be using first, the first circle with the 4 big bold letters. for example we will use amino acid AUG.

Find A on the first circle. Then we will move down to the slightly less bold letters. find U.

Now, on the last set of letters, find G and the amino acid it is paired with. We got Methionine.

2. This will explain it probably, if not lmk and I'll go in depth.

A codon is any 3 letters (nucleotides) from either DNA or RNA that creates amino acids.

3. You need 3 codons to create 1 amino acid.

If we have 5 codons represented to us, we will as a result get 5 amino acids.

Cellular respiration is a catabolic process which involves the oxidation of glucose molecules. It produces energy and is also responsible for increase in body temperature.

Cellular respiration is the process which involves the oxidation of glucose molecules in the mitochondria of cell. It results into formation of ATP molecules.

The first stage of cellular respiration occurs in the cytoplasm which is known as glycolysis. This is the step where glucose molecules are broken down into smaller molecules. A small amount of energy is also released in this process. The second stage occurs in the mitochondria of cell which is citric acid cycle. This is the step where the small molecules combine with oxygen to produce water, carbon dioxide, and a large amount of energy. The third stage is known as Oxidative phosphorylation.

Cellular respiration is affected by the temperature as the speed of biomolecules varies with temperature. They move faster and slower as temperature rise and fall, respectively.

During an exercise, the process that is causing the burning in your muscles is the production of lactic acid in anaerobic respiration.

Exercise refers to any activity that involves planned, structured, and repetitive bodily movements that are performed in order to maintain or improve the physical fitness of the body.

During exercise, the rate of cellular respiration increases, and similarly the rate of breathing increases.

At a point during the exercise, where the rate of oxygen consumption by the muscles exceeds the rate at which it is replenished during breathing, the cells of the muscles switch from aerobic respiration to anaerobic respiration.

During anaerobic respiration in the muscle cells, lactic acid is produced. The production of lactic acid in the muscles results in a burning sensation in the muscles as well as producing feelings of fatigue.

Answer: Recessive trait.

Explanation:

First generation:

In the first generation of the pedigree, the female is affected, while the male is not affected. Thus, the female must have at least one copy of the disease gene, while the male may or may not be a carrier.

Second generation:

They mate to give a normal female progeny. This female progeny has two X chromosomes, one from each parent. The female mates with a normal male and one of their sons are affected by the condition. This leads us to believe that the female was a carrier, and so was the male, and thus, the son has one affected gene from each parent, making him homozygous recessive for this condition.

Animals have organs including the stomach, liver, lungs, and heart. Plants have two different kinds of organs: stems and leaves. Organ systems are collections of organs in higher organisms.

Organ systems are a set of organs working together to maintain good biological performance; organisms are living creatures generated by an ordered collection of systems. Organs are a group of tissues that come together to form a complex structure with a special function.   The vegetative and reproductive organs of plants can be distinguished. The root, stem, and leaf are vegetative plant parts, whereas the flower, seed, and fruit are reproductive. The reproductive organs are necessary for reproduction, but the vegetative organs are crucial for sustaining a plant's existence (they carry out key tasks like photosynthesis).

In light of this, we may affirm that animals have organs such as the stomach, liver, lungs, and heart. Both stems and leaves are various types of organs in plants.

Catabolism - the breakdown of molecules to obtain energy

Anabolism - the synthesis of all compounds needed by the cells
