Answer:
D
Explanation:
Virchow's work is based off of that living things cannot exist without there being previous living things. Therefore, it has to be D because all new cells must come from currently living cells
Prophase
Metaphase
Anaphase
Telophase
Meiosis is the process of cell division by which involving gametes. Cell division is just the same for sperm and egg cells, but they have distinguishable descriptions and labels in the process. Spermatogenesis is for the males’ sperm cells and oogenesis is the process for females’ egg cells. The cell division of meiosis involves the two phases, respectively meiosis I and meiosis II. Meiosis I like mitosis is the cell division that produces diploid cells<span>. These diploid cells are cells that contain a complete pair of chromosomes which is 46. The result is two diploid cells after the first meiosis. To provide clear explanation, in contrast haploid cells only contain 23 chromosomes and are created after meiosis II which is 4 in number. </span>
Answer: Liver
Explanation:
The hepatic portal system of liver connects the capillaries of the gastrointestinal tract to the liver. The nutrient rich blood from the gastrointestinal tract reaches the liver.
The blood that is returned back to the heart is first bought to liver and then it is returned back to the heart.
From the liver after processing the blood goes into heart for further processing.
Hence, the correct answer is option d
Answer:
Genetic drift
Explanation:
Genetic drift is defined as the random change in allelic frequencies from one generation to the other.
Genetic drift is an evolutionary mechanism in which the allelic frequencies in a population change through many generations. Its effects are harder in a small-sized population, meaning that this effect is inversely proportional to the population size. Genetic drift results in some alleles loss, even those that are beneficial for the population, and the fixation of some other alleles by an increase in their frequencies. The final consequence is to <u>randomly</u> fixate one of the alleles. Low-frequency alleles are the most likely to be lost. Genetic drift results in a loss of genetic variability within a population.
Genetic drift has important effects on a population when this last one reduces its size dramatically because of a disaster -bottleneck effect- or because of a population split -founder effect-.
Looks like the order they appear in is the correct order.
1. Question-wording bias
2. Under-coverage
3. Response bias
