In tomatoes, tall (D) is dominant over dwarf (d) and smooth fruit (P) is dominant over pubescent fruit (p), which is covered wit

h fine hairs. A farmer has two tall and smooth tomato plants, which we will call plant A and plant B. The farmer crosses plants A and B with the same dwarf and pubescent plant and obtains the following numbers of progeny: Progeny of: Plant A Plant BDd Pp 122 2 Dd pp 6 82 dd Pp 4 82 dd pp 124 4 a.What are the genotypes of plant A and B

Answer:

The correct answer would be - Dd Pp.

Explanation:

As it is given that tall D is dominant over dwarf d and smooth plant Pis dominant over pubescent p so the the genotype of dominant trait that is tall and smooth tomato plants would be DDPP . similarly the recessive trait that is dwarf and pubescent plant would be ddpp

Thus, the cross between these would be -

DD PP x ddpp

And gametes would be - DP,DP, dp, and dp.

So, all the 16 offspring would have Phenotype would be heterozygous tall and smooth and DdPp genotype .

Thus, the correct answer would be - Dd Pp.

tekilochka [14]

Answer:

can ,synthesize specific proteins

Explanation:

Hormones are chemical signals secreted by animals and plant that are capable of regulating body activities and maintain homeostasis.

They are transported in the circulatory system of the body

The action of hormones can be seen after the hormone has bound to its specific receptor found inside the cell.

For instance, steroid hormone and the thyroid hormones can pass through the plasma membrane to their receptors inside the cells.

When they bind with their receptors, the target cells will synthesize specific proteins that produce the characteristic effect of the hormone.

What is the mass of an element with 15 protons, 13 electrons, and 11 neutrons?
RSB [31]

Answer:

B. 26amu

Explanation:

The nucleus of an atom in an element contains protons, electrons and neutrons. The proton number equals the electron number in a neutral atom. The proton number is also called the atomic number, denoted by Z.

The mass number also called Atomic mass unit (amu) in this case, of an element is the sum of the proton number and the neutron number in the atom of that element. The mass number is denoted by A.

Hence, A = Z + N

Where A = Mass number

Z = Proton (atomic number)

N = Neutron number

In this question, N is 11 while Z is 15

Hence, the mass number of the element in the question, in AMU, is 15 + 11 = 26amu.

In the diagram, how many angles are alternate exterior angles with angle 5?
strojnjashka [21]

Answer:

One.

Explanation:

The attached figure shows the diagram of the given question.

We need to find how many angles are alternate exterior angles with angle 5?

Exterior angle = Angle that is made outside of the shape

Alternate angle = an angle opposite of a transversal line of another angle.

From the figure, 8, 7, 9, 10, 12, and 11 are the angles that are on the same transversal. 8, 7, 9, 10, and 12 are just exterior. It means that 11 is the alternate exterior of angle 5. So, only one angle is alternate exterior angles with angle 5.
