The surface of the human red blood cell is dominated by a small number of abundant blood group active proteins. The major proteins are the anion transport protein (band 3) which has AB(H) activity, and Glycophorin A which has MN activity.
A small number of abundant blood group active proteins dominate the surface of the human red blood cell. Proteins that coat the surface of red blood cells are called antigens.
What are red blood cells?Red blood cells, also known as red cells, red blood corpuscles, haematids, erythroid cells, or erythrocytes, are the most common type of blood cell and the primary means of delivering oxygen to the body tissues of vertebrates.

Given the following crosses give the outcome. What can be the blood types of their children.
Type AB blood x type 0 blood
Answer:
For this question, you have to draw a punnet square
Explanation:
A B
i Ai Bi
i Ai Bi
For AB blood type, one parent can give either an A or a B. For the other parent because they are 0 blood type that means that they are negative for both factors.
For someone who would be A, they could be AA or Ai( but that is irrelevant for this question)
The i reffers to no antigen markers, it is kind of just a placeholder. You could have written (O,O) instead

Based on the structure of proteins, how would you explain why Beau’s coat hair changed from straight to curly? Be your explanation describes what is happening at the molecular level to proteins
Beau’s coat hair changed from straight to curly because of Denaturation occurs.
What is happening at the molecular level to proteins?When a chemical relaxer and heat are applied to curly hair, the protein present inside your hair gets denatured. Due to this denaturation of protein in the hair, the hair is soft and flexible which can be converted into any direction and different styles can be done. If a chemical perm or relaxer is applied to straight hairs, it also denatures the protein and make the hair curly.
Thus, Denaturation occurs.

What are Interphase, prophase I, metaphase I, anaphase I, telophase I, prophase Il, metaphase II, anaphase II, telophase Il in meiosis.
The stages of meiosis 1 and meiosis 2 is discussed below:
What is meiosis?Eukaryotic cells (plants, animals, and fungi) reproduce sexually through a process called meiosis. Chromosome reduction is the process by which haploid cells are created from diploid cells, which are cells with two complete and identical sets of chromosomes.
The number of chromosomes in each cell is halved during meiosis I, which starts with one diploid parent cell and ends with two haploid daughter cells.
Maintaining the number of chromosomes in each cell, meiosis II begins with two haploid parent cells and finishes with four haploid daughter cells. Before meiosis II, homologous pairs of cells divide into chromosomes while in meiosis I.
These chromosomes are further divided into sister chromatids during meiosis II. Meiosis II does not include genetic material crossing across or recombining between chromosomal pairs, whereas meiosis I do.
This happen in the prophase contains five subphases and is lengthy and complex during meiosis I. The equatorial plane in meiosis II is aligned 90 degrees differently than in meiosis.
Therefore interphase1, prophase 1, metaphase 1, anaphase, and telophase 1 are the stages of meiosis 1 and prophase Il, metaphase II, anaphase II, and telophase Il in meiosis 2.

the 5’ end of the dna molecule is considered ____, while the 3’ end of the dna molecule is considered the _____
The 5’ end of the dna molecule is considered five prime, while the 3’ end of the dna molecule is considered the three prime.
Thus, The backbones of DNA's two long polymers of basic units, known as nucleotides, are comprised of sugars and phosphate groups that are connected by ester bonds.
These two strands are anti-parallel because they move in the opposite directions of one another. Each sugar has one of four different nucleobases (bases) molecules attached to it.
The genetic code is made up of the order of these bases, and it subsequently dictates the order of the amino acids in proteins. The 5′ (five prime) and 3′ (three prime) ends of DNA strands are referred to as the ends.
Thus, The 5’ end of the dna molecule is considered five prime, while the 3’ end of the dna molecule is considered the three prime.

The pH value is a unit of measure which describes the degree of acidity or alkalinity of an aqueous solution. In other words, pH demonstrates the quantitative information of the activity of an acid or base based on hydrogen ion concentration.
The mathematically formal definition of pH is the negative logarithm of hydrogen ion concentration:
[tex]pH \ \ = \ \ -\log_{10}\left[H^{+}\right][/tex].
Hence, if the concentration of [tex]\text{H}^{+}[/tex] ions in a solution is [tex]1.0 \ \times \ {10}^{-7} \ \text{M}[/tex],
[tex]pH \ = \ -\log_{10}\displaystyle{\left(1 \ \times \ {10}^{-7}\right)} \\ \\ pH \ = \ -\log_{10}\displaystyle{\left(1\right) \ - \ \log_{10}\left({10}^{-7}\right)} \\ \\ pH \ = \ 0 \ - \ \left(-7\right) \\ \\ pH \ = \ 7[/tex].

Describe artificial selection, and explain how it is different from natural selection.
Answer:
Starting with natural selection, the most robust and most intelligent animals survive over the weakest. The weak animals eventually die off because they can't keep up with nature. Artificial selection isn't natural; certain species are being targeted on purpose and decide whether to stay alive or not. At this point, it is not at all about whether the species can survive or not because it's most likely being protected.
