B. law of conservation of mass
This is why the total amount of and element before and after a chemical reaction is constant.
Answer:
B
Explanation:
This is the answer that I think is correct
Answer:
The term secretion refers to the cell that releases a substance into the extracellular space.
Explanation:
When a cell or organ or gland produce and secretes substance in to extracellular space,this biochemical process is called as secretion.
The secretory products may be hormone, enzymes etc.
This process facilitates the movement of material from one place to another place.
For example, Pituitary gland produce and release prolactin hormone that induces breast cells to produce lactation during sucking process done by baby.
Pituitary gland also secrete different hormones that acts on different glands like adrenal, testes, ovary, thyroid gland etc that in turn produce different hormones like adrenaline,testosterone,estrogen,progesterone, TSH,T3, hormone etc.
Answer:
F = dominant, free earlobes
f = recessive, attached earlobes
father is "ff" then he has only two recessive attached earlobe alleles meaning he can only have attached earlobes. This is his phenotype, the visible trait produced by the genotype.
The mother is said to be "Ff". She has one dominant free earlobe allele (F) and one recessive attached allele (f). The dominant allele gets expressed as the visible trait (phenotype). = free earlobes
Answer:c. each of two alleles for a given trait segregate into different gametes.
a. it possible to determine the genotype of an individual of unknown genotype who exhibits the dominant version of a trait
Explanation:
The law of segregation of genes is examplifed with MEIOSIS 1 ,where sister chromatides ( alleles of a gene on the same locus) separated and behave independently of each other by positoning themselves on different spindles at Metaphase 1 for crossing over and independent assortment.
They migrated independently at Anaphase 1 to reach the equators which afrer telephase 1 and Telophase 2 i are located in different gametes.
Therefore the alleles of the genes behaved independently of each other,carting different genetic components to gametes.
