Please Help! What molecules need to travel through ATP synthase to help it create ATP?

Effectus [21]

Answer:

The proton gradient produced by proton pumping during the electron transport chain is used to synthesize ATP. Protons flow down their concentration gradient into the matrix through the membrane protein ATP synthase, causing it to spin (like a water wheel) and catalyze conversion of ADP to ATP.

Explanation:

That's the answer but not all of it just pick out the actual answer.

The bees wing are moving very fast the best wings are much smaller than it body ?

marishachu [46]

Explanation:

It is true that the wings of the bee move very fast. The wings are smaller than their body and it is believed to be difficult for the wings to lift the whole body of the bee.

Sometimes, bees carry nectar and pollen with itself which again increases their weight. It has been found that the wings do not move up and down rather moves to and from. Since air is denser, it tries to push the air downwards and lift itself upwards.

Asexual reproduction produces _____.

Sauron [17]

Asexual reproduction produces a direct clone of the parent.
The other terms are related to sexual reproduction.

Asexual reproduction or asexual reproduction is a mode of reproduction, which (as opposed to sexual reproduction) corresponds to the capacity of living organisms to multiply alone, without a partner, without involving the fusion of two gametes of opposite sexes.

The mechanism of the reproduction is by mitosis, budding or scissiparity.

1. Flower position, stem length, and seed shape are three characters that Mendel studied. Each is controlled by an independently

maria [59]

Answer:

a. 1/64 AATTDD

b. 1/64 aattdd

c. 8/64=1/8 AaTtDd

d. 2/64 = 1/32 AATTDd or aattDd or AAttDd or aaTTDd

Explanation:

Available data:

Flower position: Axial (A) is dominant to Terminal (a)

Stem length: Tall (T) is dominant to dwarf (t)

Seed shape: Round (R) is dominant to wrinkled (r)

Cross:

Parental) AaTtDd x AaTtDd

Knowing that these four genes assort independently, then we can infer that the F1 will have the next genotypic proportions for each gene:

AA= 1/4

Aa =2/4

aa = 1/4

TT = 1/4

Tt = 2/4

tt = 1/4

DD = 1/4

Dd = 2/4

dd = 1/4

This is the same as developing a Punnett square for each gene separately.

Knowing this, to get each of the mentioned genotypes for each trait, we must multiply their respective genotypic proportions, like this:

a. homozygous for the three dominant traits, AATTDD

AA1/4 x TT 1/4 x DD 1/4 = AATTDD 1/64

b. homozygous for the three recessive traits, aattdd

aa 1/4 x tt 1/4 x dd 1/4 = aattdd 1/64

c. heterozygous for all three characters, AaTtDd

Aa 2/4 x Tt 2/4 x Dd 2/4 = AaTtDd 8/16=1/8

d. homozygous for axial and tall, heterozygous for seed shape. There are four possibilities, all of them with the same result:

AATTDd --> 1/4 x 1/4 x 2/4 = 2/64=1/32

aattDd ---> 1/4 x 1/4 x 2/4 = 2/64=1/32

AAttDd ---> 1/4 x 1/4 x 2/4 = 2/64=1/32

aaTTDd ---> 1/4 x 1/4 x 2/4 = 2/64=1/32
