Answer: ATP

Explanation:Each organelle supports different activities in the cell. Mitochondria, for example, are organelles that provide eukaryotes with most of their energy by producing energy-rich molecules called ATP. Prokaryotes lack mitochondria and instead produce their ATP on their cell surface membrane.

What is the probability that each of the following pairs of parents will produce the indicated offspring? (Assume independent as

ASHA 777 [7]

Answer:

(a) AABBCC × aabbcc->AaBbCc → 1

(b) AABbCc × AaBbCc->AAbbCC → 1/32

(d) aaBbCC × AABbcc->AaBbCc → 1/2

Explanation:

In such cases we calculate the probability of each allelic pair separately.

(a) AABBCC × aabbcc -> AaBbCc

Aa Aa Aa Aa Bb Bb Bb Bb Cc Cc Cc Cc

↓ ↓ ↓

4/4 = 1 4/4 = 1 4/4 = 1

In case of gene A, out of the 4 probable allelic combinations, 4 will be Aa so the probability is 4/4 = 1.

In case of gene B, out of the 4 probable allelic combinations, 4 will be Bb so the probability is 4/4 = 1.

In case of gene C, out of the 4 probable allelic combinations, 4 will be Cc so the probability is 4/4 = 1.

So, the total probability of getting AaBbCc = 1 x 1 x 1 = 1.

(b) AABbCc × AaBbCc -> AA bb CC

AA AA Aa Aa BB Bb Bb bb CC Cc Cc cc

↓ ↓ ↓

2/4 1/4 1/4

In case of gene A, out of the 4 probable allelic combinations, 2 will be AA so the probability is 2/4.

In case of gene B, out of the 4 probable allelic combinations, 1 will be bb so the probability is 1/4.

In case of gene C, out of the 4 probable allelic combinations, 1 will be CC so the probability is 1/4.

So, the total probability of getting AA bb CC = 2/4 x 1/4 x 1/4 = 1/32.

AA Aa Aa aa BB Bb Bb bb CC Cc Cc cc

↓ ↓ ↓

2/4 2/4 2/4

In case of gene A, out of the 4 probable allelic combinations, 2 will be Aa so the probability is 2/4.

In case of gene B, out of the 4 probable allelic combinations, 2 will be Bb so the probability is 2/4.

In case of gene C, out of the 4 probable allelic combinations, 2 will be Cc so the probability is 2/4.

So, the total probability of getting AaBbCc = 2/4 x 2/4 x 2/4 = 1/8.

(d) aaBbCC × AABbcc->AaBbCc

Aa Aa Aa Aa BB Bb Bb bb Cc Cc Cc Cc

↓ ↓ ↓

4/4 = 1 2/4 4/4 = 1

In case of gene A, out of the 4 probable allelic combinations, 4 will be Aa so the probability is 4/4 = 1.

In case of gene B, out of the 4 probable allelic combinations, 2 will be Bb so the probability is 2/4.

In case of gene C, out of the 4 probable allelic combinations, 4 will be Cc so the probability is 4/4 = 1.

So, the total probability of getting AaBbCc = 1 x 2/4 x 1 = 1/2.

Matter moves in the same direction as wave travels

m_a_m_a [10]

Answer:

Not all matter and waves move the same direction, some do though

Explanation:

transverse wave--matter in the medium moves back and forth at right angles to the direction that the wave travels

compressional wave--matter in the medium moves back and forth along the same direction that the wave travels

What would you expect to happen if sea otters were removed from this food web?

makkiz [27]

The food web would be likely destroyed because one animal will not have nothing to eat out of the food we’d and then that’s how the food web will be messed up

Explain how ecosystem can change even if people are not involved

andrew11 [14]

Answer:

The animals could change it. For example, a bunny could dig a hole in the ground, making a home for other animals inside of it, too, changing the animals' living environment.

Or natural disasters could change their environment, too. For example, if a landslide occurred and covered a pond, frogs and snakes could lose their living areas and food, which would make them have to move to a different area, changing another ecosystem.
