Answer:

10x6=60mins

12 cells an hour

1.5= 1 hour and 3 minutes

10x3=30mins

6 cells

=18 cells

Answer:

18 cells

Explanation:

1.5 hours is 90 minutes. 2 cells per 10 minutes so it 18 cells.

A strand of dna contains the base sequence agtt. what is the sequence of the complementary strand of dna?
Ratling [72]
TCAA
A IS TO T
AND G IS TO C
A is complementary to t and c is complementary to G. So when you see A you put T and visa versa.

Genrish500 [490]

The question is incomplete. Here is the complete question.

You are studying a population of ground squirrels. You trap 100 individuals and find 9 that have a light colored coat and the rest have a dark coat. You know that light coat color is recessive in ground squirrels. What is the allele frequency for the light coat allele  and the dark coat allele? How many of the dark coated individuals do you expect to be heterozygotes at the coat color gene? Assume the population is at H-W equilibrium.

Answer: Allele frequency for light coat: q = 0.3;

              Allele frequency for dark coat: p = 0.7;

             There will be 42 heterozygote;

Explanation: A population in H-W equilibrium is a population which doesn't change from one generation to the next if there are no disturbing factors, as migration or mutation.

It follows the equation: p^{2}+2pq+q^{2}=1.

p represents the frequency of the dominant allele;

q represents the frequency of the recessive allele;

2pq represents heterozygote individuals;

The sum of frequencies of both alleles must be 1, i.e.: p+q=1

For the population of squirrels:

  • Frequency of recessive allele

q^{2} = \frac{9}{100}

q = \sqrt{\frac{9}{100}}

q = 0.3

  • Frequency of dominant allele

p+q=1

p=1-q

p=1-0.3

p = 0.7

  • Frequency of heterozygote

2pq = 2*0.7*0.3 = 0.42

In a population of 100 individuals: 0.42*100 = 42

The allele frequency for the light coat is 0.3; for the dark coat is 0.7.

It is expected to have 42 heterozygote individuals in this population.

What is the only thing that can scratch corondum?​
tatuchka [14]

Answer:

The only thing that can scratch Corundum is diamond.

Explanation:

We refer to the Mohs Hardness Scale for the hardness levels. We can see that Corundum is a level 9 which is the second highest so at a level 10 we see diamond, therefore diamond is the only thing that can scratch Corundum.

The anterior portion of the body of most annelids, such as the earthworm, is adapted for sensing the environment.
Diano4ka-milaya [45]

Answer:

The answer is False. Although sensitive cells are <u>more abundant</u> in the <u>anterior portion</u> of the annelid´s body, in general, they are arranged in all the segments.

Explanation:

Annelids, such as the earthworm, have a variety of sensory cells:    

  • <u>Mechanoreceptors</u>, disposed of in groups in <em><u>each segment</u></em> of their body.  
  • <u>Photoreceptors</u>: Light-sensitive cells. Although they are <em><u>located in the whole </u></em>body, they are <em><u>abundant in anterior and posterior segments</u></em>, concentrated in the intern and dorsal part of the epidermis.
  • <u>Humidity receptors</u> are the most sensitive cells and are <u>located in the first segments</u> of the earthworm body
  • <u>Chemoreceptors</u>: sensorial cells cumulus forming a prominent tubercle with prolongations that extends through the cuticle. These tubercles form three rings <em><u>in each segment</u></em> but are especially <em><u>abundant in the anterior part</u></em> of the body.

The tegument is very rich in free nervous terminations, which functions might be tactile.
