To check whether Earnest and Denise could have a baby with Type O blood, draw a Punnett square for a father who has blood Type A

Nutka1998 [239]

Answer:

Answer is explained below and also see the document attached below for Punnett square.

Explanation:

ABO blood type (A, B, AB, or O) is based on the presence (or absence) of the A and B antigens in the red blood cells. The blood type, A has only the A antigen (and has anti-B antibodies) while the blood type, B has only the B antigen (and had anti-A antibodies). Also in the AB blood type, both A and B antigens are present (but has no antibodies) while in the O blood type, both A and B antigens are absent (but has both antibodies).

The blood type is inherited from the parents and the offspring inherits one of the two alleles from each parent. The ABO blood type has three types of alleles: IA, IB, and i. Here, I is a term for antigen (isoagglutinogen).

The IA and IB alleles are dominant while the i allele is recessive. The blood type A is formed by either two IA alleles (IA IA ) or IA i. So, the genotype of blood type A is IA IA or IA i. The blood type B is formed by either two IB alleles (IB IB ) or IB i. So, the genotype of blood type B is IB IB or IB i. The O blood type is formed only by two i alleles (ii). So, the genotype of blood type O is ii. The IA and IB alleles (IA IB) give the AB blood type, which is an example of codominance (the traits of both the alleles are visible in the phenotype). The genotype of blood type AB is IA IB.

If the parents have blood type A and B, then they can have an AB blood type offspring. If the parents have blood type A and B and they both are heterozygous (IB i and IA i), then they can also have a O blood type child.

Here, the father has blood Type A (IA i genotype) while the mother has blood Type B (IB i genotype). Both the parents are heterozygous (IB i and IAi), so the possible genotypes of their child are IA IB (blood type AB), IA i (blood type A), IB i (blood type B) and ii (blood type O).

i.e., <u> Blood Type </u> <u>Genotype </u>

A IA IA or IA i

B IB IB or IB i

AB IA IB

O ii

The drawing below illustrates a small portion of the molecules that make up a cell membrane. What is the primary function of the

Ket [755]

Answer:

The correct option is b

Explanation:

Phospholipids are lipids that contains a phosphate group, which forms the "head" of the molecule and is hydrophilic (water loving). The "tail" of phospholipids is made of two fatty acids which are hydrophobic (water fearing). The phospholipid in the cell membrane acts as a selectively permeable barrier that regulates what goes in and out of the cell <u>thereby protecting the cell from some external molecules and ions</u>.

Describe how some cells make food molecules!

dimaraw [331]

Answer:

All living cells release energy from food molecules through cellular respiration and/or fermentation. Some cells make food molecules using light energy through the process of photosynthesis.

Two ways to cells get energy: cellular respiration and fermentation.

Fermentation: Fermentation, chemical process by which molecules such as glucose are broken down anaerobically.

Cellular respiration: Cellular respiration is the process through which cells convert sugars into energy. To create ATP and other forms of energy to power cellular reactions, cells require fuel and an electron acceptor which drives the chemical process of turning energy into a useable form.

Polymerization and the break down of a polymer are two opposite reactions. What role does a water molecule play in both of them?

ladessa [460]

<span>In the process of polymerization, a chain of similar smaller molecules called monomer join together to create very large molecules called polymer. Through this chemical reaction, water is created as a by-product. In contrast to hydrolysis or breaking down of polymers, a water molecule is used to break the covalent bond that hold the components of a polymer.</span>

Which of the following INCORRECTLY describes a polymer? Which of the following INCORRECTLY describes a polymer?

Len [333]

Answer:

A. ATP is a polymer of phosphates.

Explanation:

ATP is not a polymer of phosphates. It is a rather a complex organic molecule that has its main function to provide energy.

Starch and glycogens are polysaccharides or polymers of glucose or simply put, they have glucose subunits.

Nucleotides are biological molecules consisting of 3 major sub units which are the nitrogenous base, the phosphate acid and the 5 carbon (ribose) sugar. They are the building blocks of DNA and RNA and hence monomers.

Amino acids are basically organic compounds that contain amine (-NH2) and carboxyl (-COOH) functional groups, along with a side chain (R group) specific to every amino acid molecule. They are bond together by a peptide bond between the -NH2 and -COOH group to furthet form polypetides. Proteins in the same vein are called polypeptides which is a chain of amino acids.
