Dominant is the first gene variant in a phenotype from the two alleles of a gene and recessive has effect on the third allele of a phenotype.
Explanation:
The genetic phenomenon of masking of chromosome with one variant of allele or predominating the impact of one gene on its chromosomal copy is Dominance. In this phenomenon the first variant of gene is known as ‘dominant’ and the second one is ‘recessive’.
This phenomenon is not inherited by phenotype, it has a relative effect on two alleles of a gene where one is dominant on other and the recessive is on third allele. Dominant allele has functional protein but recessive does not have it.
The race cares produce waste answer by
1. polluting the environment
2.by emitting waste that led to human health problems
The race cares generate waste which led to pollution of environment. The use of motor oil, brake fluid and leaded gasoline led to production of toxic chemicals These chemical have been shown to cause cancer, birth defect and kidney problems.
Answer:
Poisning by 2-deoxyglucose syops the glycolysis process which leads to cardiovascular and respiratory symptoms. Due to property of inhibiting the enzyme reqquired for glycolysis, glucokinase. So, there is no ATP production takes place.
Explanation:
Answer:
b. actively transport Cl- from the ECF to the external environment.
Explanation:
Chloride cells are cells that are found in the gills of teleost fishes which pump large amount of sodium and chloride ions out from the extracellular fluid (ECF) into the sea or environment against a concentration gradient in marine fish.
The opposite of this process occurs in freshwater fishes where the gills of freshwater teleost fish, cause an influx of sodium and chloride ions into the fish from the environment, also against a concentration gradient.
Mechanism of action
Salt water teleost fishes take in large amounts of seawater to decrease osmotic dehydration. The excess of ions derived from seawater is thrown out of the teleost fishes through the chloride cells. These cells employs active transport on the basolateral (internal) surface to diffuse in chloride, which then is pumped out of the apical (external) surface, straight into the surrounding environment. Such mitochondria-rich cells are located in the region of the gill lamellae and filaments of teleost fish.
Answer:
The cells at the end of meiosis II must have half the number of chromosomes because, if they didn't have, the reunion of both gametes with diploid number of chromosomes for example, in gametes would form twice the number chromosomes.
