if the job of a cell was to swim a long distance to an egg with a flagella, then it would need more of what organelle?

kicyunya [14]

If a particular job of a cell was to swim a long distance to an egg with a flagella, then it would need more mitochondria. As mitochondria undergo cellular respiration and essentially utilize the carbohydrates for that particular cell to produce the final product of ATP high energy containing molecules needed for the movement.

Identify the phenotypes for the offspring of a parent with the genotype IBi and a parent with the genotype IAIA. type O type A,

agasfer [191]

<span>I is dominant, i is recessive. The A's and B's are just show which allele I is. When there is just one dominant allele, it masks the recessive in blood typing. Remember IA and IB are codominant.

O is always ii
A is IAi (heterozygous) or IAIA (homozygous)
B is IBi (heterozygous) or IBIB (homozygous)
AB is always IAIB

Remember: You get one allele from each parent!

1. Father must be ii, mother must be ii, so all children must be ii.

2. Father is IAIA (the homozygous one), the mother is IBIB, so the only possibility for the children is IAIB, because you get one allele from the father and one from the mother.

3. Father is IAi, mother is IBi, so the children can be any of the blood types, because they can have all the combinations of genotypes.

4. Father is ii, mother is IAIB. Children can only be IAi or IBi.

5. Father is IAIB, mother is IAIB. Children can be IAIA, IBIB, or IAIB.

Example of Punnett square:
3. Father is type A, heterozygous, mother is type B, heterozygous
Father must be IAi (heterozygous)
Mother must be IBi (heterozygous)

_______IA ____ i

IB____ IBIA____IBi

i _____ IAi______ii

Sorry, that was difficult on here, hope it's understandable.
The father's alleles run across the top, the mother's are on the side, you follow to where they meet to find the possibilities for the children. IBIA (AB blood type), IBi (B), IAi (A), and ii (O) are the possibilities in this case.

Hope that helps!</span>

A student does an experiment for a science fair to study whether temperature affects the timing of a cricketâ€™s chirps. The stu

nexus9112 [7]

The frequency of chirps increases as the temperature increases. The correct option is B. <em>The chirps occur closer together as the temperature increases. </em>

-------------------------------

<h2><u>Available data:</u></h2>

<h3>Data recorded by the student </h3>

<em><u>Day Temperature Average time between chirps (sec)</u></em>

1 21 2. 5

2 22 2. 6

3 23 2. 2

4 24 2. 3

5 25 2. 0

6 26 1. 8

7 27 1. 9

8 28 1. 8

9 29 1. 4

10 30 1. 2

11 31 1. 5

<u>12 32 1. 1</u>

In this experiment the student recorded the time in seconds <u>between </u><u>chirps</u>.

We can see that <em>as the </em><em>temperature increases</em><em>, in general, the</em><em> time</em><em> between</em><em> chirps decreases</em>.

At 21ºC the time between chirps is 2.5 seconds

At 26ºC the time between chirps is 1.8 seconds

At 32ºC the time between chirps is 1.1 seconds

According to this information, if the average time between chirps decreases with the temperature increase, we can assume that<em> the </em><em>frequency</em><em> of chirps </em><em>increases</em><em> as the temperature gets higher. </em>

<h3>Options,</h3>

<em>A) The higher the temperature, the fewer chirps there will be in 10 seconds</em>.

Wrong. The number of chirps in 10 seconds will depend, not only on the frequency but also on how long the chirps last. Since the student did not record the time of chirps, we can not make this conclusion.

<em>B) The chirps occur closer together as the temperature increases</em>.

True. The chirps increase in frequency as the temperature increases, so they occur closer together.

<em>C) The chirps become farther apart as the temperature increases</em>.

Wrong. We can see how the time between chirps decreases as temperature increases, meaning that they are closer not farther.

D) There is no relationship between temperature and the time between chirps.

Wrong. If we make a graph we will see the tendency and the relationship between chirps and temperature.

Graphs usually explain the relationship between variables. In this example, the relationship would be inverse.
