Anemia is a disorder where there is not enough hemoglobin in the blood. Why would this disorder lead to shortness of breath?

1 answer:

5 0

Anemia is a medical condition that occurs when your blood doesn't have enough red blood cells. Red blood cells carry oxygen to the organs in your body. If you don't have enough red blood cells, your body doesn't get enough oxygen. This may cause you to feel tired or shortness of breath.

In Drosophila, the genes crossveinless and Stubble are linked, about 7 map units apart on chromosome 3. cv is a recessive mutant

stealth61 [152]

Answer:

0.035

Explanation:

cv+ is the wild-type dominant allele over cv, therefore:

cv+cv+ and cv+cv cause wild-type phenotype for crossveinless
cv cv causes the crossveinless phenotype

Sb is a dominant mutant allele over wild-type Sb+, therefore:

Sb Sb and Sb Sb+ cause Stubble phenotype
Sb+ Sb+ causes wild type phenotype for Stubble

<h3>Test cross</h3>

It's the cross between the heterozygous female with a homozygous recessive male. Remember that cv and Sb+ are the recessive alleles.

$\frac{cv\ Sb^+}{cv^+\ Sb}$ X $\frac{cv \ Sb+}{cv \ Sb+}$

-The male produces only 1 type of gamete: cv Sb+

-The female produces 4 types of gametes:

cv Sb+ ] Parental
cv+ Sb ] Parental
cv Sb ] Recombinant
cv+ Sb+ ] Recombinant

The genes are linked and separated by 7 map units. A distance of 7 mu means that 7% of the resulting gametes will be recombinant. Because there are 2 possible recombinant gametes, each of them will appear in 3.5% of the cases.

The genotypes and proportions of the offspring resulting from the test cross can be seen in the Punnett Square. The phenotypically wild-type individuals will have the genotype cv+ Sb+ / cv Sb+ (heterozygous for crossveinless and homozygous recessive for Stubble) and a 0.035 proportion.

11) Assume a population of deer has a crude birth rate of 26 per 1,000/yr, a crude death rate of 15 per 1,000/yr, an immigration

Llana [10]

Answer:

9 per 1,000/yr.

Explanation:

The population growth rate is 9 per 1,000/yr.

The rate of growth of population is determined by the following formula:

Growth rate = B - D + I - E

Where B = birth rate, D = death rate, I = immigration, and E = emigration

In this case, B = 26, D = 15, I = 7, and E = 9. Substitute these values into the equation of growth rate.

Growth rate = (26 - 15) + (7 - 9)

= 11 - 2 = 9

Hence, the growth rate of the deer's population is 9 per 1,000/yr.

The biconcave cells in blood that lack nuclei when they are mature are the __________

34kurt

The biconcave cells in blood that lack nuclei when they are mature are the red blood corpuscles.

Explanation:

The blood contains a combination of cells especially the Red blood corpuscles, white blood corpuscles and the blood platelets. The major function of the Red blood corpuscles is to carry oxygen and supply to all the parts of the body from the lungs and similarly carry carbon dioxide and supply to all parts of the body . To facilitate this it does not have a nuclei.
