''Selective breeding uses two horse parents with the desired traits to increase the chances of passing the desired traits on to offspring'' is the correct statement.
What is meant by selective breeding?By selecting which male and female animals or plants would normally reproduce sexually and generate offspring together, people can employ animal and plant breeding to selectively acquire certain phenotypic features.
Choosing parents with certain traits to breed with one another in order to generate kids with more desired traits is known as selective breeding. For thousands of years, humans have carefully selected a variety of animals and plants, including agricultural species that produce more.
The goal of selective breeding is to produce cattle with desirable features that are strongly heritable and can thus be passed down from generation to generation. For instance, selective breeding was used to create broccoli, cauliflower, and cabbage from the wild mustard plant.
Since each attribute includes two genes, it is difficult to produce purebreds or animals with homozygous traits. By choosing two animals with the desired expressed characteristic, the likelihood of having offspring with the desired trait improves even when there is still no "hidden" recessive trait. Given that genes may change and are affected by the environment, it is not guaranteed. statement C

when the heterozygous genotype results in a phenotype
When the heterozygous genotype results in the phenotype, it means that the two alleles for a particular gene are different.
The combination of the two alleles influences the physical characteristics or traits of an organism. This means that one allele may be dominant and the other allele may be sheepish. Depending on the combination of the alleles, the organism will parade certain physical characteristics. For illustration,
if one allele is for brown eyes and the other is for blue eyes, the existent may have a phenotype of hazel eyes, which is a combination of the two alleles. In this case, the heterozygous genotype has redounded in a phenotype of hazel eyes.

How did the color of the leaf change when exposed to light?.
Leaf colour varies from a deeper to a lighter shade of green when maintained in the dark because leaves need light to accomplish photosynthesis. It can also become yellow occasionally.
The amount of light present has a direct correlation with the formation of the pigment chlorophyll, which is necessary for photosynthesis.
Because of this, the light that is reflected by the leaves is less red and blue and appears green instead. Actually, there are two pigments that make up chlorophyll: chlorophyll a and chlorophyll b.
The procedure for a change in leaf colour. The number of pigments changes as the leaves get ready to fall from the trees, which causes the colour of the leaves to alter in the autumn. Throughout the growth season, all leaves gradually lose chlorophyll, and this loss quickens before leaf fall.

Reaction 6: Succinate Oxidation to Fumarate Succinate is converted to fumarate by oxidation. FAD is converted to FADH2 during this oxidation.
what is succinate ?
Succinic acid (CH2)2(CO2H)2 is a dicarboxylic acid having the formula (CH2)2(CO2H)2. The name is derived from the Latin word succinum, which means amber. In living organisms, succinic acid takes the form of an anion, succinate, which serves several biological functions, including being a metabolic intermediate that is converted into fumarate by the enzyme succinate dehydrogenase in complex 2 of the electron transport chain, which is involved in the production of ATP, and serving as a signalling molecule that reflects the cellular metabolic state. It is sold as the food additive E363. The tricarboxylic acid cycle generates succinate in the mitochondria (TCA). Succinate may depart the mitochondrial matrix and act in both the cytoplasm and the extracellular environment, altering gene expression patterns, influencing the epigenetic landscape, and exhibiting hormone-like signalling.

Only around 3,000 of the 300 million ejaculated sperm make it to the area around the egg. And the foetal phase is the period from the ninth week till delivery.
The cortical reaction, also known as the progressive block to polyspermy, involves the release of enzymes from cortical granules to the oocyte's surface. This destroys the oocyte's sperm receptors and also causes any sperm still attached to receptors to separate. These occurrences guarantee monosperm. Azoospermia is the term used in science when there are no sperm present in the ejaculate. It may be obstructive, where a blockage prevents sperm from entering the ejaculate, or it may be nonobstructive, where the diminished sperm production by the testis is to blame.

What are the 3 main purposes of mitosis?.
Answer:
The following are the roles of mitosis:
1. It is the way of asexual reproduction for unicellular organisms.
2. Replacement of damaged and worn-out cells is crucial.
3. It is largely concerned with growth. Mitosis generates cells that are necessary for the body to gain bulk.
Explanation:
1. Growth and development
Mitosis is the process by which an embryo develops after meiosis has generated a gamete that has united with another gamete to become an embryo. This growth occurs throughout the lives of plants, animals, and fungi. The original chromosomal set is so retained.
2. Replacement of cells
This happens when the original cell is injured or damaged. New cells are formed to replace the destroyed ones. Healing from a cut or a shattered bone are two examples of this. When old cells die, new ones take their place to guarantee that the body continues to operate.
3. Sexual reproduction is not possible.

why is compartmentalization important in eukaryotic cells
Organelles are specialised, have unique PHs, and have the ideal circumstances for particular required reactions.
More surface area is made available by compartmentalization, facilitating the exchange of materials between cells and their surroundings.
Why is compartmentalization important?
Let's look at a building construction example. If a structure is to be constructed by just one worker, the project will take decades to finish because the worker will quickly become exhausted and make several mistakes. The same applies in a cell. A cell has to carry out numerous tasks concurrently, and for those tasks, numerous events must occur simultaneously in that cell, such as protein synthesis, energy production, lipid synthesis, etc., all without disrupting other processes.

How many types of RNA are involved in the process of protein synthesis?There are three types of RNA involved in the process of protein synthesis: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA).
Messenger RNA (mRNA) carries the genetic information from the DNA to the ribosome where it is translated into a specific sequence of amino acids. Transfer RNA (tRNA) brings the specific amino acids to the ribosome and matches them with the codons (sequence of three nucleotides) on the mRNA. Ribosomal RNA (rRNA) is a component of ribosomes and forms the structural scaffold for the translation process. Together, these three types of RNA work together to carry out the process of protein synthesis.
The process of protein synthesis begins with the transcription of the DNA code into RNA, which is then translated into a specific sequence of amino acids that make up the protein. The sequence of amino acids is determined by the sequence of nucleotides in the DNA or RNA.
