Biology
1 answer:
alexandr402 [8]3 years ago
5 0

Answer:

C. Evolution is a change of allele frequency from one generation to the next

Explanation:

Evolution is the gradual change that occurs to living organisms over successive generations. According to Charles Darwin, these changes aid in the adaptation of the species of an organism to their environment. In other words, it makes them better fit.

Charles Darwin further stated that since evolution is dependent on natural selection i.e selection of the best fit by environmental factors, the changes that the organism undergo are genetic. Hence, evolution is a change of allele frequency from one generation to the next.

Answer:Dehydration

Explanation:

Dark urine is usually indicative of dehydration; but there could be more reasons responsible for it. Ideally, when you eat or drink something, it goes through your digestive tract, circulatory system and then to your kidney. Kidneys are where everything is filtered and urine is produced. Urine contains the harmful toxins which need to be eliminated from the body. Darker urine is more concentrated. It is indicative of the fact that unnecessary toxins and wastes are circulating in your body which could mess with your health. This, again, depends on how much fluids you drink throughout the day. But there could be many other reasons responsible for the same.

What is the Mechanical energy when
Scilla [17]

Answer:

ME = 20 * m, where m is the mass of the pendulum

Explanation:

As we know that mechanical energy is the sum of kinetic energy and potential energy.

Since the Pendulum at its highest point has zero velocity, its kinetic energy at this point is equal to zero.

Thus, here in this mechanical energy will be equal to the potential energy only.

Potential energy is equal to the product of gravity constant, mass of the body and the height of the pendulum

Thus,

ME = PE\\

PE = m * g* h\\PE = 10 * 2* m\\

PE= 20m

Hence,

ME = 20 * m

How does the chromosome number of daughter cells compare with the amount of chromosomes in parent cells?​
riadik2000 [5.3K]

Answer:

Mitosis creates two identical daughter cells that each contain the same number of chromosomes as their parent cell. In contrast, meiosis gives rise to four unique daughter cells, each of which has half the number of chromosomes as the parent cell.

wariber [46]

Answer:

one normal girl

One normal boy

One carrier girl

One colour blind boy

Explanation:

Haemophilia is a sex linked feature as it is transmitted with the chromosomes determining sex.

In humans,the male has XY and the female has XX.the Y chromosome is usually genetically empty.so as mall received his Y chromosomes from his father,he cannot inherit his father's sex linked traits .but women can as they receive and X chromosomes from their fathers.so a cross between a carrier woman Cc and a normal man C result in;

XX--CC

XX--Cc

XY--C

XY--c
