A horse has 64 chromosomes and a donkey has 62. Using your knowledge of meiosis, explain why a cross between a horse and a donke
nlexa [21]
Ok, so when a horse (with 64 chromosomes) is crossed with a donkey(that has 62 chromosomes), each parent give its child half of its chromosomes. [64/2=32] [62/2=31]. So the mule gets 31 pairs of chromosomes plus 32 pairs of chromosomes. That equals 63 total chromosomes. In order to be a parent, it must give <span>half of its chromosomes to its child. [63/2=31.5] You can't have half a chromosome, so the mule is a sterile organism. Let me know if you have questions.</span>

In a certain triangle ABC , A equals 30°, B equals 50°, and the side AB equals 3 in. Use a protractor and a straightedge to cons
natali 33 [55]
If you were to compute this, Angle C should be equal to 100°.

In a triangle, all angles sum up to 180°.

In triangle ABC, where the m∠A =30° and m∠50°:

m
∠A + m∠B + m∠C = 180°
30° + 50 + m∠C = 180°
80° + m∠C = 180°
m∠C = 180° - 80°
m∠C = 100°

The triangle should look like the picture attached.

il63 [147K]

Answer:

The correct answer is A) Conformation.

Explanation:

Proton pumps are usually molecules that are able to change its conformation in order to transport molecules from one side to the other. The amino acid sequence cannot be changed, because it would change completely the function of the protein. For example, the sodium/potassium pump changes its conformation in order to move these molecules from one side of the membrane to the other.

Does female sperm and male sperm look different
nikdorinn [45]

Answer:

the Y chromosome is smaller than the X chromosome.

Explanation:

The male has an X and Y sex chromosome which is an exception to the general rule that homologous chromosomes are identical as the Y chromosome is smaller thus enabling it to swim faster than the X chromosome. The Y chromosome also has a longer lifespan compared to the X chromosome. The male genotypes is XY. Males are heterogametic as they produce two types of gametes, one carrying the X and the other carrying a Y chromosome.
