Answer:
A. 1/16
Explanation:
If we break the dihybrid cross of AaBb X AaBb into individual monohybrid crosses:
Aa X Aa :
A a
A AA Aa
a Aa aa
1/4 of the progeny will be homozygous for dominant allele (AA)
Similarly, in cross Bb X Bb 1/4 of the progeny will be homozygous for dominant allele (BB)
Hence, in cross AaBb X AaBb:
1/4 * 1/4 = 1/16 will be homozygous for both the dominant alleles.
If your choices are the following, then the correct answer is C:
a. The aerobic bacteria were able to capture the sunlight and generate sugars from it.
b. The aerobic bacteria helped protect the cell against desiccation.
c. The aerobic bacteria metabolized sugars and generated large amounts of ATP.
d. The aerobic bacteria helped protect the cell against predation.
This is actually the endosymbiotic theory of how we humans (and other organisms alike) have evolved to have mitochondria inside our cells. Evidence to support this is that mitochondria have their own DNA different from ours.
<em>A</em> can't be the answer because that is more related to plants. <em>B and C </em>are also wrong because they simply do not provide those functions.
C all land on the united stated is publicly owned and may be accessed by the public

My mother told me “Family is always a priority!” And i understand that virtue now because my family means a lot to me and without them i wouldn’t be here
D) dilating sureface blood vessels
When you're out in cold weather, your skin triggers shivering so the blood vessels will contract and keep you as warm as possible. But if there's a heat wave, you'll sweat to increase the blood flow to the capillaries, which in turn increases sweating. This process cools you off as the water evaporates from your skin.
