Answer: I think the answer is true
Explanation: If you think about it, the terrestial planets ( being venus, earth, mars, and mercury) are made up very little gas which are carbon dioxide, nitrogen and oxygen, and the gas giants ( being jupiter, saturn, neptune, and uranus) have gases such as hydrogen and helium. Thus meaning, the terrestial planets could be a part of it and the gas giants are the most. So yes, the answer is true.
Answer:
Yes.
Explanation:
Bacteria are the simplest of creatures that are considered alive. Bacteria are everywhere. They are in the bread you eat, the soil that plants grow in, and even inside of you. They are very simple cells that fall under the heading prokaryotic. You don't usually get infected by dead bacteria, because They get recycled. Unlike larger organisms, when single-celled organisms die, they usually undergo a process called lysis, in which the cell membrane disintegrates.
The correct answer is reciprocal cross.
The reciprocal cross is referred to a cross between a male of a specific strain with the female of another strain and the vice versa.
The reciprocal ensures that the inheritance of a certain character in the offspring in independent of the sex. This cross was done by Mendel, by switching the pure breeding lines.
Even after changing the sexes, he got the same results in F1 progeny, which suggest the inheritance of a character is independent of the sex.
After the completion of first trimester that is 8 weeks of conception, the baby is almost 1 inch grown. At this stage, the baby is referred as fetus. At this stage, all the organs as well as limbs becomes visible except for the sex organs.
The heart of baby beats rhythmically. Eyes and the eyelids are completely visible. Both the forelimbs and the hind limbs are formed, and fingers buds are also visible.
At this stage, the fetus looks like a human. The umbilical cord is also clearly visible at this stage.
Hence, the correct answer is 8th week.
