1. If a pea plant’s alleles for height are tt, what is true of its parents?

1 answer:

4 0

1. C) Both parents contributed a recessive allele
The offspring is homozygous for the recessive allele, which means it has two copies of it. Because each parent contributes one copy of the gene, this means that both parents contributed the recessive allele.

2. D) The offspring can be tall or short

The first cross between TT and tt will yield an F1 generation with the genotype Tt. When this generation is self-pollinated, the cross may result in the following genotypes:
TT, Tt, tt
Which means that the offspring can be tall or short.

A 35 kg child moves with uniform circular motion while riding a horse on a carousel. The horse is 3.2 m from the carousel's axis

Andrews [41]

<h2>Hello!</h2>

The answer is:

b. $\frac{2.11m}{s^{2}}$

The centripetal acceleration or radial acceleration is present when an object is moving to describe a circular path. The centripetal acceleration is always perpendicular to the direction of the velocity and going inwards and towards the center.

The centripetal acceleration can be calculated using the following equation:

$CentripetalAcceleration=\frac{v^{2}}{RadiusOfMotion}$

From the statement we know that:

$v=TangentialSpeed=\frac{2.6m}{s} \\R=3.2m$

So, calculating we have:

$CentripetalAcceleration=\frac{{2.6^{2} \frac{m}{s} }}{3.2m}=\frac{{6.76\frac{m}{s} }}{3.2m}=\frac{2.11m}{s^{2} }$

So, the correct answer is:

b. $\frac{2.11m}{s^{2}}$

What’s is the unit ratio of platelets to whit blood cells in a microliter of blood?

____ [38]

Answer:

33.3

Explanation:

Normally there are 4000 to 11000 WBCs in a microliter of blood averaging almost 7500. While there are 150,000 to 350,000 platelets in a microliter blood of a normal person averaging almost 250,000. Thus the ratio can be as 250,000 :7500 resulting in 33.3. If a range is to be given, it ranges from 31.8 to 37.5 per microliter of blood.

Identify the difference between the more traditional Mendelian and Neomendelian modes of inheritance (qualitative inheritance) a

Ann [662]

Answer:

Answer explained below

Explanation:

quantitative inheritance results in a continuous range of multiple phenotypes. The final phenotype results from both gene and environmental influences. For example, human height

WHILE

Qualitative inheritance results in distinct and separate phenotypic categories. The final phenotype results from gene action. For example, fruit fly eye color.
