<h2>Hey There! _____________________________________ </h2><h2>Answer: </h2>

\huge\boxed{Option A}

<h2>_____________________________________ </h2><h3>PEA PLANT: </h3>

Pea plant has purple color flowers dominant over white color flowers.

Purple flower dominant allele is P

White Flower recessive allele is p

We would get White flower pea plant only when the recessive allele is in HOMO.ZYGOUS condition

_________________________________________________________

<h3>CONDITIONS: </h3>

Hom.ozygous Dominant Alleles: PP (Purple Flower)

Heter.ozygous Dominant Alleles: Pp Purple Flower)

Hom.ozygous Recessive Alleles: pp (White Flower)

<h2>____________________________________ </h2><h3>CROSS: </h3>

Whenever we cross Heterozygous Dominant(Pp) purple flower with another Heterozygous dominant (Pp purple flower), we get 75% of the flowers PHENOTIPICALLY(physical appearance) white flowered, and 25 white flowered Because as you can see in the picture,

The P1 is Pp

The P2 is Pp

When we cross them,

It has 4 offsprings,

PP Hom.ozygous Purple flower  

Pp Heterozygous Purple flower

Pp Heterozygous Purple flower

pp Hom.ozygous white flower

Thus the answer is 75% as there are phynotypically 3 purple flowers present

Answer:

75%

Explanation:

The allele for purple flowers (capital P) is dominant.

The allele for white flowers (lowercase p) is recessive.

If one allele is capital P, it doesn’t matter if the other allele is another capital P or a lower case p, the capital P will dominate and purple flowers will show up.

The Punnett Square shows:

PP, Pp, Pp, and pp

• 3 of the offspring have at least one dominant and capital P, so purple flowers show up.

• 1 of the offspring has two lowercase and recessive alleles (p), so white flowers show up.

3/4 or 75% of the offspring will have purple flowers.

kykrilka [37]

Living in a tropical environment where one learns to orient oneself through a vertical landscape of tall trees and speckled light is part of spatial orientation.

<h3>What is the rain forest zone?</h3>

The tropical rain forest zone is the zone that is known to have a very high amount of rainfall for most of the year. The rain forest zone often has a lot of luxuriant trees that blossom all year round and serve as a breeding ground for many insects such as mosquitoes.

Most of the trees in the tropical rain forest zone are arranged in strata where the tallest trees often form a sort of canopy in the area thereby reducing the light that gets to the pants that are found below and keeping the area cool.

Hence, living in a tropical environment where one learns to orient oneself through a vertical landscape of tall trees and speckled light is part of spatial orientation.

What is the atom of the element boron?
Agata [3.3K]

The atomic number is 5. The atomic number gives the number of protons. Protons which have a positive charge are balanced by an equal number of electrons in a neutral atom.  Boron number 5 has five protons and therefore as a neutral atom also has five electrons. Boron atomic number 5 has five electrons in its ground state.  Commonly Boron will lose 3 electrons leaving 2 electrons in its most common ionic form.
