What is the difference between Myeloid and Lymphoid hemopoiesis?

1 answer:

6 0

If the abnormal cells are primarily granulocytes (which destroy bacteria) or monocytes (which produce large cells called macrophages, which digest foreign substances and diseased cells), the leukemia is classified as myelogenous. If the abnormal cells are mainly lymphocytes (which orchestrate the immune system’s response to infection or disease), the leukemia is classified as lymphocytic.Leukemia arises from malfunctions in stem cells within the bone marrow that cause abnormal white blood cells to flood into the bloodstream. Leukemias are classified as either myelogenous (also called myeloid) or lymphocytic depending on which types of white blood cells are affected.

The term for energy of movement

lara31 [8.8K]

Answer;

-Kinetic energy

Explanation;

The energy associated with motion or movement is called kinetic energy.

-Kinetic and potential energies are found in all objects. If an object is moving, it is said to have kinetic energy (KE). Potential energy is stored energy and the energy of position; gravitational energy.

-An object that has motion - whether it is vertical or horizontal motion - has kinetic energy. Kinetic energy is calculated by the formula 1/2mv², where m is the mass of the object and v is the velocity of the object.

-Therefore, kinetic energy depends upon two variables: the mass (m) of the object and the speed (v) of the object.

When pink sweet peas were self-pollinated and the seeds were collected and sown, the following flower colors were obtained: Red

Pavlova-9 [17]

Answer:

c. 1:2:1

The results are consistent with incomplete dominance for this trait, with pink flowers being heterozygous.

Explanation:

If flower color were determined by a gene showing incomplete dominance, the possible genotypes and phenotypes are as follows:

RR- red
ww - white
Rw - pink

If pink sweet peas are self-pollinated, then a cross between two heterozygous individuals is done (Rw x Rw).

From this cross the expected ratios are:

1/4 RR (red)
2/4 Rw (pink)
1/4 ww (white)

So the null hypothesis is that the observed results exhibit a 1:2:1 ratio.

<h3>Chi square test</h3>

$X^{2} = \sum \frac{(Observed - Expected)^2}{Expected}$

The observed frequencies were:

34 Red
76 Pink
40 White

Total 150

The expected frequencies for our null hypothesis are:

1/4 x 150 = 37.5 Red
2/4 x 150 = 75 Pink
1/4 x 150 = 37.5 white

$X^{2} = \frac{(34- 37.5)^2}{37.5} + \frac{(76- 75)^2}{75} + \frac{(40- 37.5)^2}{37.5}$

$X^2=0.5067$

The degrees of freedom (DF) are calculated as number of phenotypes - 1; in this case DF = 3-1 = 2.

If we look at the Chi square table, for 2 DF and a probability of p0.05, the critical value is 5.991

Our X^2 value of 0.5067 is less than the critical value, so we do not reject the null hypothesis. The results are consistent with incomplete dominance for this trait, with pink flowers being heterozygous.

Answer:melanism

Explanation:albino is when an animal has no melanin, which is the chemical that causes pigment (color). Melanism is when an animal has too much melanin and is completely black. That animal is melanistic.
