Answer:
The correct answer would be zygote...blastocyst...embryo...fetus.
The fertilization of sperm and egg results in the formation of zygote. It receives genetic material from a male as well as a female parent.
It divides with the help of mitotic divisions and results in the formation of 2, 4, 8, and 16 celled stages.
It results in the formation of the hollow spherical ball of cells termed as a blastocyst. The cells are distributed to form the outer layer termed trophoblast and inner cell mass which gives rise to the embryo.
Trophoblast help in the implantation of the blastocyst into the uterine wall.
The cells of the embryo undergo organogenesis during different organs such as heart, brain, lungs et cetera are formed.
In humans, almost 9 weeks after the fertilization the developing embryo is considered a fetus.
The fetus development continues until birth.
The correct answer is B
The genetic codes language in all living organisms is the same. This is to say that the molecules of life namely DNA and RNA share the same make up in all living things .
There are five types of nucleotides in nature which are the building blocks of RNA and DNA and these are the same in all living organisms . These nucleotides are Adenine, Thymine, Guanine, Cytosine and Uracil.
According to base pairing rules, in all DNA molecules Adenine will always pair with Thymine while Guanine will always pair with Cytosine.
This rule is the same with RNA except that here Thymine is replaced with Uracil. Otherwise the base pairing rule applies in all living organisms, that is to say it is universal.
Answer: There is a 25% chance the baby will have blue eyes. If you both carry the recessive blue eye gene.
B.
C. winter solstice because if the North is having summer, the south would be having the opposite due to the direction the earth is tilted in orbit
<h2>Answer:</h2>
Based on the information given we can not say pea aphid as an autotroph. Because pea aphid ability to produce ATP in the presence of sun is due to the light-capturing pigment that it gains from the genes transferred from fungi.
As pea aphid do not have any chloroplast and it cannot fix carbon so it is not a true autotroph. We can say it false autotroph because it can produce ATP in the presence of sunlight and can show increased production of ATP at the higher level of pigment.
