Answer:
The correct answer is mast cells.
Explanation:
Mastocyte also is known as a mast cell refers to a migrant cell of connective tissue, which comprises various granules high in heparin and histamine. Mainly it is a kind of granulocyte obtained from the myeloid stem cell, which is a component of the neuroimmune and immune systems. These cells are similar to basophils, however, they are found within the tissues rather than circulating in the blood.
By injecting Mesenchymal Stem Cells with ability to express high amount of Akt or protein kinase B in myocardium, researchers witnessed restored cardiac function and inhibition of ventricular remodeling. The effect was seen after two weeks of administration of cells. The culture containing hypoxic Akt-MSCs (conditioned medium) inhibits apoptosis or cell death induced due to hypoxia. Also, it triggers in vitro contraction of cardiomyocytes, the cardiac cells specifically responsible for contraction function.
The desired functional improvement can occur in short time which is less than 72 hours, the reason for which was hypothesized as paracrine action of cells. Hypothesis was proved by upregulation of genes that code for factors responsible for above mentioned effects (apoptosis and contraction). The factors are FGF-2, VEGF, HGF etc.

Answer:
A female Drosophila of unknown genotype was crossed with a white-eyed male fly, of genotype (w = white eye allele is recessive, w+= red-eye allele is dominant.) Half of the male and half of the female offspring were red-eyed, and half of the male and half of the female offspring were white-eyed.If the trait is dominant, one of the parents must have the trait. Dominant traits will not skip a generation. If the trait is recessive, neither parent is required to have the trait since they can be heterozygous.The female fly had to be heterozygous, Xw+ Xw.

When it is in space it is called a meteorite, when coming into the atmosphere it is a meteor, and when it hits earth it is a meteoroid.
Answer:
Pheromones
Explanation:
Pheromones play an important role in the behavioral isolation of insect species. These compounds serve to identify individuals of the same species and of the same or different sex. Evaporated molecules of volatile pheromones can serve as a wide-reaching chemical signal. In other cases, pheromones may be detected only at a short distance or by contact.
