Cross a pure A type blood with a pure B type blood;write the phenotype, genotype, and ratios

Biology
1 answer:
Irina18 [472]3 years ago
8 0
If one parent has the pure A blood type (both alleles are A) is with genotype AA The other parent has the pure B blood type (both alleles are B) is with genotype BB
 Crossing these two: AB AB AB AB
<span>which means that all of the children will have AB blood type (phenotype). This happens because of the codominance. The A and B alleles are codominant and therefore, if an A is inherited from one parent and a B from the other, the phenotype will be AB.</span>

The enzyme telomerase solves the problem of replication at the ends of linear chromosomes by which method?
adell [148]
<h2>Answer </h2>

The method is by adding various small DNA chains such as TTAGGG, that develop a hairpin turn.

<u>Explanation </u>

The method is by adding various small DNA chains such as TTAGGG, that develop a hairpin turn. Telomerase is an RNA dependent DNA polymerase means an enzyme that can make DNA using RNA as a template. The ends of linear chromosomes called telomeres that protect genes from getting deleted as cells continue to divide. The telomerase enzyme attaches to the end of chromosome complementary bases to RNA template are added on 3 ends of the DNA strand.

compare the physical and chemical properties of a compound to those of the elements of which it is composed.
Inessa05 [86]

Answer:

Compound: These are made of the various type of same or different elements. These elements show a specific ratio in a particular compound.

The physical properties are traits of a particular compound or element that can be observed physically like the state of matter, color, odor, and other. The chemical properties and physical properties of compounds and elements they formed are different.

It is not comparable as the elements have no or very little individual value in a compound. For instance, water made of hydrogen and oxygen, where water is liquid and constituents are gas.

Arrange the following estuarine zones in decreasing order of salinity.
Maksim231197 [3]

Answer:

Euhaline  ⇒  Polyhaline  ⇒  Mesohaline  ⇒  Oligohaline

Explanation:

Let's first define each of these levels:

- Polyhaline: a category of salinity that has medium-high levels of salt

- Mesohaline: a category of salinity that has medium levels of salt

- Oligohaline: a category of salinity that has low levels of salt

- Euthaline: a category of salinity that has high levels of salt

Now, we can order these in decreasing order of salinity:

Euhaline  ⇒  Polyhaline  ⇒  Mesohaline  ⇒  Oligohaline

A(n) _____ is a group of three bases on trna that is complementary to a specific mrna codon. poly-a tail cap codon anticodon
Tema [17]

A(n) <u>anticondon </u>is a group of three bases on trna that is complementary to a specific mrna codon. poly-a tail cap codon anticodon

The main function of an anticondon is to form a pair with the condom by mating in order to form an RNA chain, this chain is a sequence of three nucleotides that form a unit of genetic code in a transfer RNA molecule.

<h3>What is molecule?</h3>

It is the union of two or more atoms by chemical bonds, conserving the physical and chemical properties of that substance.

For example: the water molecule is H2O.
