How does natural selection change the frequency of genes or traits over many generations? Biology students conducted an experime

nt mimicking genetic variation and coloration. Students used different colored beans to represent animals that might be prey: mice, for example. A student in each group was the predator: a hawk. Beans (mice) were randomly scattered on multicolored floor tiles, each color within four tiles. The hawk collected mice (beans) for 10 seconds. Mice not eaten reproduced. Three generations of data a shown in the table.
Genetic variation helps to drive natural selection and potentially, evolution. Red, white, and striped beans (mice) represent offspring that are the product of meiosis and sexual reproduction. Black and speckled beans (mice) are the result of mutations. Using the student data analyze the effects of these mutations on natural selection.

A) The color mutations provided a survival advantage to these two populations of mice.

B) The advantage of the mutations is dependent on the environment and external conditions.

C) While mutations provide genetic variation they did not play a role in natural selection.

D) The speckled mutation provided an advantage while the black mutation was a disadvantage for survival.

Answer:
D) The speckled mutation provided an advantage while the black mutation was a disadvantage for survival.

The speckled mutation provided an advantage while the black mutation was a disadvantage for survival.

Natural selection refers to the observation that organisms that are more suited and adapted to their environment live long enough to survive and reproduce thereby passing on their favorable characteristics to their offspring.

The mutation in which the mice became speckled was shown to be an advantage from the table. Hence, the speckled mutation provided an advantage while the black mutation was a disadvantage for survival.

Help please will give brainliest to anyone who is good at ​
SpyIntel [72]

Answer:

The way to figure this this type of question out is card by card. So the first card in the second hand is 2 in 52 (It can match either of the cards in the previous hand). × 1 in 51 ( it has to match the card that was not matched by the first card and there are 51 choises left). So 2 in 52 = 1 in 26 x 1 in 51 = 1 in 26 x 51 = 1 in 1326

Explanation:

Hope this helps! Remember to reword it incase your teacher checks for plagiarism! I recommend Quillbot to help!

meriva

Individuals with chronic alcoholism are predisposed to intracranial bleeding and hypoglycemia secondary to abnormalities in the (c) liver.

Intracranial bleeding is the bleeding that occurs inside the skull. This leads to accumulation of blood that exerts pressure on the brain, ultimately leading to brain damage. The causes for bleeding can be various like: trauma, rupture of blood vessel, high blood pressure, or tumors.

Hypoglycemia is the condition of low levels of sugar in the blood. The most common reason for this condition is the medications taken to control diabetes. However, it can also happen due to other reasons. The general symptoms of the conditions are: palpitations, anxiety, confusion, etc.
