Complementary pairing goes like this:
A pairs with T and
C pairs with G. Nothing about this changes unless you get to mRNA (But we won't go into that) :)
So if you have a strand that goes TCG GA then your pairing will look like this:
T A
C G
G C
G C
A T
Hope this helps!! :)
Answer:
The earliest known life-forms are putative fossilized microorganisms, found in hydrothermal vent precipitates, that may have lived as early as 4.28 Gya (billion years ago), relatively soon after the oceans formed 4.41 Gya, and not long after the formation of the Earth 4.54 Gya.

Answer:
b) there are 56 deer in 1000 acres of area.
Explanation:
If a person has 1000 aces of land and a local wildlife biologist tell him that on every 18 acres only one deer is present so in 1000 acres there are 56 deer are present.
calculation;
1 deer ------ 18 acres
x --------- 1000 acres
by cross multiplication, we get
18 x = 1000
both side divided by 18, we get
x = 55.5
by rounding off we get
x = 56
Answer: Developmental biologist
Explanation:
<u>Undifferentiated cells are cells that are able to develop into a specific cell variant</u>. They are the basic cells in biology that all other cells derive from. An example is stem cells which are cells that could still become any kind of cell that the body needs.
<u>Differentiated cells are cells that have changed from one type to another one more specialized</u>. For example, a neuron is a differentiated cell because they have a certain type of gene expression that makes them specialized to perform functions in the brain.
Developmental biology is the study of how organisms grow and develop. For that purpose, it studies the genetic control of cell growth, differentiation of stem cells, regeneration, asexual reproduction and morphogenesis. All these processes gives rise to tissues, organs and the anatomy of an adult organism. So, this kind of scientist study several cellular processes carried out by undifferentiated cells which will become specialized.
