Answer:

If the paired chromosomes fail to separate during meiosis in the female, then the resulting daughter cells will receive either 2 or no copies of chromosome 21. If the resulting egg with 2 copies of chromosome 21 is fertilized with a normal sperm, the resulting zygote with be trisomy 21

What is the main difference between weather and climate?
8_murik_8 [283]

Answer: Option B) The length of time over which the conditions are measured

Explanation:

Weather is the atmospheric condition of a given area over a short period of time, usually days to several months

Climate, on the other hand, is the atmospheric condition of a given area over a long period of time, usually over 2 years.

Thus, weather and climate differ based on the length of time over which the conditions are measured.

In the formula, E K = 1/2 • m • v 2 if mass (m) was doubled, how much would kinetic energy
Viktor [21]

Answer:

mass doubled makes KE twice as large

velocity doubled makes KE 4 times as large

Explanation:

Try it with an example

m = 4

v = 8

KE = 1/2 m * v^2

KE = 1/2*4 * 8^2

KE = 1/2 * 4 * 64

KE = 128

Now double the mass

m  = 8

v = 8

KE = 1/2 8 * 8^2

KE = 1/2 8 * 64

KE = 4 * 64

KE = 256 double what it started out as.

Now do it again.

m = 4     That was the original mass

v = 16

KE = 1/2 4 * 16^2

KE = 2 * 256

KE = 512

When the velocity is doubled the KE becomes 4 times as big.

4*128 = 512

Describe how a eukaryotic cell can be viewed as four interacting systems: the nucleus, cytosol, endomembrane system, and semiaut
mars1129 [50]

Answer and explanation;

Nucleus; houses a cell's DNA and its processes include protein, replication and packaging for cell division. It is also the site for transcription.

Cytosol; coordinates a responsible to the environment, metabolism and motor proteins.

Endomembrane system; includes the nuclear envelope (surrounds nucleus), rough and smooth ER, golgi body, lysosomes?vacuoles, peroxisome and plasma membrane.

Semiautonomous organelles; mitochondria (animals) and chloroplast (plants) which provide energy for the cell.

Setler79 [48]

Answer:

Lobsters are adapting to cooler temperatures.

Explanation:

Adaptation may be defined as the phenomena that involves the physical, physiological and chemical changes in the organisms that helps to adapt themselves in their environmental condition.

The adaptation may bring genetic changes in the next generation as well. The lobsters movement per year demonstrates that they are trying to adapt in their environment. The cooler temperatures is favorable for the growth and adaptation of Lobsters.

Thus, the answer is Lobsters are adapting to cooler temperatures.
