Answer 1

Hey There! _____________________________________ Answer: _____________________________________ PEA PLANT:

Pea plant has Round Seed dominant over Wrinkled Seed.

Round Seed allele is R

Wrinkled Seed allele is p

_____________________________________CONDITIONS:

Hom.ozygous Dominant Alleles: RR (Round Seed)

Heter.ozygous Dominant Alleles: Rr (Round Seed)

Hom.ozygous Recessive Alleles: rr (Wrinkled Seed)

_____________________________________CROSS I:

Whenever we cross Heter.ozygous Dominant(Rr) with Hom.ozygous recessive (rr), we get 50% ROUND SEEDS PHENOTIPICALLY(physical appearance), Because as you can see in the picture,

The P1 is Rr

The P2 is rr

When we cross them,

It has 4 offsprings,

Rr Round Seed

rr Wrinkled Seed

Thus the answer is 50% round seed as there are 2 out of 4 heter.ozygous dominant round seed.

_____________________________________ CROSS II:

Whenever we cross Hete.rozygous Dominant(Rr) with another Heter.ozygous Dominant (Rr), we get 75% ROUND SEEDS PHENOTIPICALLY(physical appearance), Because as you can see in the picture,

The P1 is Rr

The P2 is Rr

When we cross them,

It has 4 offsprings,

RR Round Seed

Rr Round Seed

Rr Wrinkled Seed

rr Wrinkled Seed

Thus the answer is 75% round seed as there are 3 out of 4 hom.ozygous and hete.rozygous dominant round seed.

_____________________________________CROSS 3:

Whenever we cross Homo.zygous Dominant(RR) with Heter.ozygous Dominant (Rr), we get 100% ROUND SEEDS PHENOTIPICALLY(physical appearance), Because as you can see in the picture,

The P1 is RrR

The P2 is Rr

When we cross them,

It has 4 offsprings,

RR Round Seed

Rr Wrinkled Seed

Thus the answer is 100% round seed as there are 4 out of 4 hetero.zygous and homo.zygous dom.inant round seed.

Write the formula for acceleration.

Answers

Answer: Acceleration (a) is the change in velocity (Δv) over the change in time (Δt), represented by the equation a = Δv/Δt. This allows you to measure how fast velocity changes in meters per second squared (m/s^2). Acceleration is also a vector quantity, so it includes both magnitude and direction.

in which direction do particles in a solution move during passive transport

Answers

During the passive transport, the particles move from a higher concentration to a lower concentration without the need for energy expenditure or spending. The passive transport is seen in the cell too.

What is the importance of the different types of transportation?

In the cell, different types of transport are seen, such as active transport and passive transport; in active transport, energy is used, while energy is not used in passive transport. The movement of molecules across the cell plasma membrane is important because it allows cells to get rid of unwanted molecules. Passive transport does not require energy, and many nonpolar small molecules and gases can cross the lipid plasma membrane barrier and go into and out of the cell while, in this passive transport process, they save the cell's energy.

Hence, during the passive transport, the particles move from a higher concentration to a lower concentration without the need for energy expenditure or spending.

In a chemical analysis of a sample of animal tissue, which element would most likely be found in the smallest quantity?

Answers

Answer:

Iodine

Explanation:

Iodine is needed by animals because the body's metabolic rate is controlled by the action of an iodine hormone, called thyroxine, which is secreted by the thyroid gland in the neck.

If the animal fails to supply enough iodine through food to be able to make a normal amount of this compound, then the thyroid gland enlarges or expands trying to create enough, resulting in a common type of goiter.
