How many molecules of water are made in maltose molecules?

slega [8]

Avogadro's number tells us there are 6.022 x 1023 molecules of water per mole of water. So, next we calculate how many molecules there are in a drop of water, which we determined contains 0.002775 moles: molecules in a drop of water = (6.022 x 1023 molecules/mole) x

You cross two fruit trees. one tree produces lemons with spiky leaves and bumpy fruit. the other produces lemons with smooth lea

Triss [41]

the alleles are as follows;

L - lemons with bumpy fruit (dominant)

l - lemons with smooth fruit (recessive)

S - smooth leaf (dominant)

s - spiky leaf (recessive)

parents

one tree - lemons with smooth leaves and smooth fruits

one tree - lemons with spiky leaves and bumpy fruits

if parents show recessive phenotype , this means that the genotype should be recessive homozygous - ll / ss

if parents show dominant phenotype genotype is dominant homozygous or heterozygous

parents - S_ ll x ssL_

f1generation-

bumpy fruits with smooth leaves - SsLl

bumpy fruits with spiky leaves - ssLl

since offspring are bumpy fruits it should either be Ll /LL, but one parent is ll therefore for the offspring to be Ll/ll the other parent should have homozygous LL. Then the offspring will be heterozygous for fruits

offspring have both spiky leaves - ss and smooth leaves Ss. for offspring to have heterozygous and homozygous both, since one parent is already homozygous, the other parent should have heterozygous alleles- Ss

the parents genotypes are Ssll and ssLL

mr_godi [17]

Answer:

Option-(True): The following statement is true in all sense, as the "Cytotoxic T cells and NK cells kill by secretion of proteins. The first called granzyme which forms complexes that penetrate the cell membrane and allows the passage of the apoptosis inducing protein perforin to enter the targeted cell."

Explanation:

In order to make it more difficult for the pathogens and other foreign particles to stay inside the human body, the defense mechanism of the human body system has evolved itself to great extents as there are different level of immune layers and more over cells that either helps in the recognition of these anti-bodies or attacks them to be eliminated from the given system.
As the hazardous or cancer cells which are not required to stay inside the human body is removed with the help of these lymphocytes inside the immune system of the human body.
