Answer:
Bone pain is associated with leukemia because large number of cancer cells are present in the bone marrow.
Explanation:
Leukemia may be defined as the cancer of blood cells. This cancer generally starts in the bone marrow and leads to uncontrolled division of the cell.
An individual suffering from leukemia may experience bone or joint pain. Bone pain is more common in lymphoblastic leukemia. The bone pain is mainly caused by the uncontrolled growth of cancer cell in the bone marrow.
Since mice in general, are nocturnal, I think b. is the answer..
Answer:codominance
Explanation:codominance inheritance is when both alleles of a heterozygous gene pair have full phenotypic expression. A good example is the human blood group; people with ABO blood group type AB blood have one allele for A and one for B both expressed.
Answer:
Natural selection
Darwin's theory was based on the mechanism of natural selection, which explains how populations can evolve in such a way that they become better suited to their environments over time.
Individuals have variations within their heritable traits. Some variations make an individual better suited to survive and reproduce in their environment.
If this continues over generations, these favorable adaptations (the heritable features that aid survival and reproduction) will become more and more common in the population.
The population will not only evolve (change in its genetic makeup and inherited traits), but will evolve in such a way that it becomes adapted, or better-suited, to its environment.
Explanation:
Natural selection is the process through which populations of living organisms adapt and change. Individuals in a population are naturally variable, meaning that they are all different in some ways. This variation means that some individuals have traits better suited to the environment than others. Individuals with adaptive traits—traits that give them some advantage—are more likely to survive and reproduce. These individuals then pass the adaptive traits on to their offspring. Over time, these advantageous traits become more common in the population. Through this process of natural selection, favorable traits are transmitted through generations.
Answer:
Answer D because they are also referred to as sex cells. Female gametes are called ova or egg cells and male gametes are called sperm.
