Answer:

  • The blood group of the father must be B.
  • The genotype of blood group would be I^{B}i.
  • The Rh factor of the father can either be positive or negative.
  • Thus, the genotype of Rh factor of father would be either Rr or rr.

Rh factor:

The phenotype of the mother Rh factor is positive. Thus, she can have Rr or RR as her genotype as positive is a dominant trait.

If the genotype of the mother is RR then all the offspring would be positive for Rh factor. However, one of the offspring is Rh negative, that means the mother must be heterozygous that is, Rr.

The genotype of the father can either be Rr or rr in order to produce offspring with positive as well as negative Rh.

Blood group:

The blood group of the mother is A. Thus, the genotype can either be I^{A}I^{A} or I^{A}i.

However, the blood groups of the children are O+ and B+.

Thus, the genotype of the mother must be heterozygous that is I^{A}i.

The blood group of the father must be B with genotype I^{B}i in order to produce offspring with blood group O and B.

Create a table in which you compare the components and functions of the following.
Sauron [17]

Nucleic acids, proteins, carbohydrates, and lipids are the four major types of biomolecules that form all living things. These biomolecules consists of monomers linked together by covalent bonds to form polymers.

  • Nucleic acids, proteins, carbohydrates and lipids can be classified according to their basic elements, monomer constituents, and functions.

Basic elements:

  1. Nucleic acids: Hydrogen (H); Carbon (C); Oxygen (O); Nitrogen (N); Phosphorous (P)
  2. Proteins: Hydrogen (H); Carbon (C); Oxygen (O); Nitrogen (N); Sulfur (Z)
  3. Carbohydrates: Hydrogen (H); Carbon (C); Oxygen (O)
  4. Lipids: Hydrogen (H); Carbon (C); Oxygen (O); Phosphorous (P)

Monomer constituents:

  1. Nucleic acids: nucleotides
  2. Proteins: amino acids
  3. Carbohydrates: monosaccharides
  4. Lipids: fatty acids and glycerol

Functions:

  1. Nucleic acids: contains the hereditary information to synthesize proteins
  2. Proteins: regulate metabolic processes (enzymes), the main biomolecule of cellular structures
  3. Carbohydrates: store energy (short term); form cellular structures
  4. Lipids: store energy (long term); the main component of biological membranes

Examples:

  1. Nucleic acids: DNA and RNA
  2. Proteins: lactase; collagen
  3. Carbohydrates: starch (polysaccharide); glucose (monosacharide)
  4. Lipids: phospholipids; cholesterol

On a dichotic listening task, A. people can accurately monitor two tasks at the same time, except when the tasks are both audito
RideAnS [48]

Answer:

B. people notice little about the message that they are supposed to ignore

Explanation:

In dichotic listening task people are able to concentrate on one voice while ignoring the other. It is observed that during dichotic listening task people concentrate more on one task than other. Sometimes dichotic listening task is used to examine the selective attention of brain. In the test the person is subjected to two voices simultaneously over the headphones and asked to pay attention either one or both voices. Then he is aked questions about the content.

Example; If you are talking on the phone with someone in a room  filled with voices of other people, you would be able to listen and concentrate at the voice on the phone while ignoring the other voices because of dichotic listening.

Example; If you are attending a seminar of a psychology professor and some peoples are talking in the hall you would be able to concentrate on the voice of the professor because of dichotic listening.

How does cloning work and work are the basics​
Musya8 [376]

Answer:

How cloning works: In reproductive cloning, researchers remove a mature somatic cell, such as a skin cell, from an animal that they wish to copy. They then transfer the DNA of the donor animal's somatic cell into an egg cell, or oocyte, that has had its own DNA-containing nucleus removed. ... This young animal is referred to as a clone.  

Basics of cloning:

Isolation of target DNA fragments (often referred to as inserts)

Ligation of inserts into an appropriate cloning vector, creating recombinant molecules (e.g., plasmids)

Transformation of recombinant plasmids into bacteria or other suitable host for propagation.

Screening/selection of hosts containing the intended recombinant plasmid .

How does in vitro fertilization work?
babymother [125]
There are many forms of VIF and each forms are made for different purposes. basically, you just extract a female egg and a sample of the male sperm, bad sperm can be separated via by adding specific chemicals. The sperm will then be transferred into the egg and the egg is transferred into the women. (This is ICSI) There are other forms under the category of IVF but this is one of the example. (ICSI only deals with male infertility)
