TCTCG and AGAGC are the perfect pair.
Option A
<h3><u>Explanation:</u></h3>
DNA is the genetic molecule of a living cell. The DNA stores genetic information of the species inside itself by means of particular pattern or sequence of nitrogen bases called as gene. The gene is comprised of the particular sequence of nitrogenous bases which are four in number - adenine, guanine, thymine and cytosine.
The nitrogen bases are present in both the strands of DNA and they have complementary relationship between them. The adenine forms hydrogen bonds with thymine and guanine pairs with cytosine.
Here the sequence of one strand is given as TCTCG. So according to the complementary pairing process, the opposite strand must have the sequence of AGAGC to maintain the structure.
Answer:
C. Population shrinks; 15 birds in the end
Explanation:
Let us understand some of the given terms;
immigration is a form of migration in which organisms comes into a territory.
emigration is a form of migration in which organisms leaves a place
population is a group of organisms of the same species
Given:
Population = 21 birds
Immigrant = 3 birds
Emigrants = 9 birds
Population change = total number of birds + immigrant - emigrants
= 21 + 3 - 9
= 15 birds
The population will shrink giving 15 birds in the end
Answer:
The earliest primates are found in the Paleocene epoch. :)
Answer:
The ovaries produce the egg cells, called the ova or oocytes. The oocytes are then transported to the fallopian tube where fertilization by a sperm may occur. The fertilized egg then moves to the uterus, where the uterine lining has thickened in response to the normal hormones of the reproductive cycle.
