Answer:
The pedigree chart are used to check the mode of inheritance of certain trait.
Explanation:
The pedigree is used to know the probability of the offspring getting a particular disorder or condition. It also help to discover the location of the defected gene. And through it can also be predicted that weather it will be a dominant or a recessive trait. For this pedigree data of several generations are required. Here, the phenotype ratios of the offspring can be accurately determined only when the genotypes of the parents are known.
Explanation:
Surprisingly, until recently, not much was known about the genes that control melanin production. 6 were known (MC1R, TYR, OCA2, SLC24A5, MATP and ASIP) and 17 more have been recently identified (DTNBP1, GPR143, HPS3, KITGL, MLPH, MYO5A, MYO7A, SLC45A2, TYRP1, ERCC6, GNAS, HERC2, IRF4, OBSCN, SKC24A5, TPNC2 and MITF), all of them directly or indirectly related to the process of melanin formation and distribution. Since there are so many different genes, if we count all the possible alterations, many different color variants can be produced.
The answer to this question is "Dendritic Cells". In addition to m cells, the "Dendritic cells" in the epithelium can capture pathogens directly from the lumen of the gut without disturbing other cells and processes in the epithelium of the epithelial layer.
Answer:
Plasma
Explanation:
Plasma. The liquid component of blood is called plasma, a mixture of water, sugar, fat, protein, and salts.
Answer: Option B.
The heart senses an increase in blood pressure and secrete ANF to decrease blood pressure.
Explanation:
Intinstic regulation is when a cell, tissue or organ system can adjust and respond to change in environment on it's own. The intrinsic is inherent in organ meaning the organ can maintain homeostatis within itself.
For example, the heart can perform intrinsic regulation for it self. The heart can perform myogenic regulation by reacting and responding to increase or decrease in blood pressure to keep the blood flow in normal blood vessel constant. It is a sublevel to control cardiac function.
