Answer:

The correct answer is option - 1. Chloroplasts and mitochondria replicate in a similar manner as some prokaryotes.

Explanation:

The endosymbiotic theory says that two eukaryotic cell organelles mitochondria and chloroplast have some prokaryotic especially bacteria-like characteristics and it also said that they are evolved from the symbiotic bacteria, mitochondria from alpha proteobacteria and chloroplast from cyanobacteria.

Thus, the correct answer is option A. Chloroplasts and mitochondria replicate in a similar manner as some prokaryotes.

A female fly is heterozygous for three X-linked genes. The dominant alleles are ABC and the recessive alleles are abc. She is cr
telo118 [61]

Answer:

<h2>(14+16)/1000 *100= 3</h2>

Explanation:

Parental combinations are always more common then other recombinant progenies.

A female fly is heterozygous for three X-linked genes crossed with an abc/Y male. . If single crossover occurs between a & b  and between b & c, then the double cross is that, which occurs in both.

Double cross over progeny are always least in number, so here double cross occurs are in abC 14 and ABc 16.

So we are expecting that number of double cross over progeny= (14+16)/1000 *100= 3

Verizon [17]

We are given with the data that at 10 am, the temp is 40oF. We are asked for the time when the body's temperature is equal to 80oF. In this casem we use Newtons law of cooling: T (t) = Ta + (To - Ta) e -kt. Substituing, 98.6 =  40 + (80-40) e -0.1947t. t is equal to . Hence the approximate time of death is -1.96 hrs ago or approx two hours ago. The answer is 8 am.
