Each biological parent donates one of their two ABO alleles to their child. A mother who is blood type O can only pass an O allele to her son or daughter. A father who is blood type AB could pass either an A or a B allele to his son or daughter.

prohojiy [21]

Answer:

All blood types are made compatible with each other.

Explanation:

The different types of blood showed that not all blood types are compatible with each other. This is the reason why when a doctor transfer blood, this has to be compatible with the person's blood. Otherwise, the immune system will recognize the blood cells as antigens and proceed to destroy it.

Red blood cells in its surface can have different types of proteins, the proteins or lack of it that a person has determines the type of blood (A, B, AB). Also, if the cell has the Rh protein it will be positive, and if it does not have it, it will be negative. In total, we have eight blood types A+, A-,B+, B-,AB+, AB-,0+,0-  and the compatibility depends on the proteins that a person has.

Answer:

C. Atoms can be used over and over in different molecules

Explanation:

When different compounds enter the stomach, they undergo a series of chemical reactions and are broken down. They are then used for new metabolic processes. For example, if glucose was broken down into pure Carbons, they could then react and form other molecules as needed by the body.

How do bacteria develop resistance to drugs
Elenna [48]

Answer: Bacteria gain resistance to drugs because of mutations (permanent and random changes to their DNA) which means they have changed DNA coding, giving them the ability to resist the drug fighting them off. As a result, they survive and reproduce. Over time, more and more bacteria are generated as the DNA code for resistance is passed on over generations. This results in bacteria having the ability to resist drugs. This is particularly prevalent with antibiotics.

In chickens, comb shape is determined by genes at two loci (R, r and P, p). A walnut comb is produced when at least one dominant
mariarad [96]

Answer:

in the obtained options, there is no dominant gene for the crossed pairs, therefore, no answer would be correct, however, when assigning a dominant character to the P gene, the correct answer would be:

E. Rr pp *rrPp

Explanation:

According to the information obtained we deduce:

Comb shape is produced by R and P

Comb of walnuts with an R or a P

Pink comb: 1 dominant P and R at the first locus and 2 recessive at the next locus

Pea comb: 2 recessive at the start and one dominant in the next position

1 single comb: 2 recessive at both loci

Rr pp × rr Pp will produce from the interbreeding: 2 walnuts, 1 single and 1 pea offspring.

We deduce that for the pink comb the genotype is: Rrpp

and for the pea comb it is rrPp

Rr pp × rr Pp generates crosslinks containing RrPp, rrPp, rrpp as children in a 2: 1: 1 ratio.

Can you answer these 2 questions? plsssssss
Maru [420]

Answer:

Because the Earth rotates on its axis, circulating air is deflected toward the right in the Northern Hemisphere and toward the left in the Southern Hemisphere. This deflection is called the Coriolis effect. Click the image for a larger view. Coastal currents are affected by local winds.
