Answer:

a) Right scale for right entity to be measured.

b) Minimum measured value

Explanation:

The first and foremost essential requirement for making a good set of measurements is to use a scale of measurement with which the target unit can be measured for example you cannot measure volume by a scale thus only a linear unit can be measured by a scale.

The second important thing is to look into the scale for its least measurement value as this will help to decide the right application of scale being used for measurement.

When blood flow to the brain is interrupted, less oxygen and glucose reach the brain. This causes brain damage and neurological problems.

<h3>Blood flow to the brain</h3>

Blood circulation in the brain has an important function in maintaining brain health. Blood circulation provides the brain with the oxygen and nutrients it needs to function properly.

Blood carries oxygen and glucose to the brain. The brain makes up only a small part of your total body weight, but it requires a lot of energy to function. The brain uses about 15% of the oxygen and glucose the body needs. In short, blood flow to the brain is a very important factor in maintaining brain health. If this cycle is disrupted, the brain can be damaged. As a result, many diseases and disorders related to nerve function can occur.

In mice, apricot eyes is recessive to black eyes. Tail length is governed by another gene, linked to the eye color gene. Long ta

just olya [345]

Answer:

trans

Explanation:

From the given information:

The study observes the genes present in mice for eye color and tail length. Since both genes are linked, it implies that they exist in the same chromosomes.

Black eyes is dominant over apricot eyes

Let Black eye be B and apricot eyes be b

Long tail is dominant over short tail

Let long tail be L and short tail be l

If double heterozygote(homoozygous-recessive) engage in the testcross

Then:

From the result given:

The parental combinations are:

Apricot eyes, Longtail (bL / bl) = 33

Black eyes, Short tails (Bl / bl) = 30

The recombinant genes are:

Black eyes, Long tails (BL / bl) = 17

Apricot eyes, Short tails (bl / bl) = 20

The recombination frequency relates to the distance between the two genes which can be computed as:

= (20+17)/100

= 37%

Thus; the heterozygous parent is in trans arrangement.
