C) ozone depletion.
D) fertilizer runoff.
The answer is C. ozone depletion
b. Escarpments
c. Artesians
d. Playas
Answer:
The correct answer is option A, Atolls
Explanation:
Atolls are coral reef island which surrounds lagoon. They are made up of volcanoes that resides under the water and thus these Atolls also remain hidden inside the water. This coral reef is also known as fringing reef because it forms fringes while surrounding an island below the water body . Atolls are involved in saving the island or sea.
Answer:
There will be 23 chromosomes in a sperm cell, 23 chromosomes in an egg cell, and 46 chromosomes in a white blood cell
Explanation:
Human cells are diploid in number i.e they exists in two basic sets (2N =46, where N is 23). So, cells of human body such as blood cells like white blood cells have two basic sets of chromosomes i.e 46 chromosomes, since they are produced by mitosis.
On the other hand, cells of humans involved in sexual reproduction such as the gametes (sperm and egg) have only one set of chromosomes since they are produced by meiosis - so they are haploid (N =23).
Answer:
Sperm=23
Egg cell=23
White blood cell=46
Explanation:
During cell division Meiosis produce haploid number of gametic chromosome 23.
The somatic cell contains 46 chromosome i.e diploid chromosome number. During cell division in meiosis gametes cells contains haploid number-23 chromosome which is half of the somatic cell chromosome.
During conjugation, haploid chromosome is donated by each parent to give a diploid organism with 46 chromosome number.
White blood cell contains 46 chromosome because it doesn't undergo cell division it is a somatic cell.
B) Cell growth increases toward the beginning of the healing process and slows down towards the end of healing process.
C) Cell growth slows down toward the beginning of the healing process and increases towards the end of the healing process.
Answer:
The correct answer is statement A.
Explanation:
At the time of the process of healing, the skin's inner layer gets exposed and can lead to infection, as the microbes like bacteria can invade the wounded region. Thus, in order to cope up with the condition, the body enhances the growth of the cell in that specific region so that the wound get heal quickly.
However, at the same time, in the end, the body produces various cells in order to seal up the wound. In the end, the formation of scar tissue takes place as the wound gets closed, thus, more tissue formation takes place in comparison to what was present prior to the formation of the wound. Thus, the correct statement is the first one.
B. to favor immigration from eastern and southern Europe
C. to favor immigration from northern and western Europe
D. to provide equal opportunity to immigrants from all nations
Answer: Option C
Explanation: The purpose of the national origins act of 1924 was to limit the number of people coming it the US. It is a law that rigorously limits immigration by establishing a system of nationwide quotas that bluntly differentiated against immigrants from Southern and Eastern Europe and essentially excluded Asians. The policy remained in effect until the 1960’s
C. to favor immigration from northern and western Europe
