In stage 2 of photossynthesis, NADP+ becomes NADPH by adding an H+. Where does the H+ come from?
Shtirlitz [24]
Enzymes break up water or H2O into electrons, H+ ions, & oxygen atoms. Electrons replace the "highenergy" electrons that were lost in the electron transport chain.<span>Oxygen is released and the H+ ions are also released. - So the first one would be A. splitting of water or H2O

and the second one is B :)

All plants and some algae have a complicated life cycle that includes both a multicellular diploid _______ stage and a multicell
vladimir2022 [97]

Answer: sporophyte, gametophyte, alternation of generation

Explanation:

Alternation of generation is a kind of life cycle seen in plants and algae in which the diploid asexual and haploid sexual stages exist. A sporophyte is multicellular and diploid which is an asexual stage. It produces the haploid spores through meiosis. The haploid spores germinate to produce haploid gametophyte. The gametophyte produces gametes by the process of mitosis.

What distance would be covered in 10
Brrunno [24]

Answer:

The correct answer would be - 5000 meter or 5 kilometers

Explanation:

Given:

Speed = 500 meter/minute

Time = 10 minutes

Distance would be covered = ?

Formula used:

speed = distance/ time

then, Distance = speed*time

Solution:

Putting values in the provided formula:

Distance = speed*time

distance = 500*10 meters

              = 5000 meters or 5 kilometer (1000 meter = 1 kilometer)

What are the frequencies of each offspring genotype in a cross between rr female and a rr male?
Vera_Pavlovna [14]
Since the male and the female have recessive alleles of this gene, all of their offspring will be like that too.
rr x rr cross will result in 100% of the offspring with the genotype: rr

R- dominant (but none of the parents has this allele)
r- recessive

ziro4ka [17]

Answer:

Complete question:

We are trying to determine the possible modes of inheritance for some particular human disorder. We have a very small pedigree for this disorder. Assuming the pedigree is accurate, indicate which of the six modes of inheritance are consistent with this pedigree: Select one or more Y Linked Autosomal Recessive Autosomal Dominant X-Linked Dominant X-Linked Recessive We are trying to determine the possible modes of inheritance for some particular human disorder. We have a very small pedigree for this disorder, Assuming the pedigree is accurate, indicate which of the six modes of inheritance ere consistent with this pedigree Select one or more X-Linked Recessive Y Linked Autosomal Recessive X-Linked Dominant Autosomal Dominant.

Answer:

After the analysis of this pedigree, it is clears that the inheritance pattern is X linked because the offsprings are affected with parents genotgype

Explanation:

The inheritance is X linked dominant because of the presence of one dominant gene for the affected genotype in male.

The male individuals are affected. This is therefore not a recessive inheritance in later case, it is only when the two genes are present at the same time the affected genotype will be seen.
