Answer:
single nucleotide polymorphism
Explanation:
A SNP (above) is a mutation in DNA at exactly one nucleotide (A, T, C, or G) that is present in at least 1% of the population.
For instance, let's say a certain protein relies on the sequence -TTG- at a certain position in a gene. If the sequence -ATG- is seen in that exact position in the gene (the A residue replacing the first T residue) in at least one percent of the population, this would be a SNP. If this replacement were in less than one percent of the population, it would just be a mutation.
T cells do not produce antibodies.
B cells do not produce antibodies.
B cells always circulate in the blood stream.
T cells always circulate in the blood stream.
Answer:
B cells always circulate in the blood stream

Answer:
Oceanography
Explanation:
Oceanography or the marine science studies the earth's oceans and seas. It includes tectonics in the specific ocean, water currents etc.
THERE ARE MANY BRANCHES OF THIS TOPIC:
Ecology: the study of plants and animals in the water body.
Chemical oceaography: study of chemistry of the oceans
Metorology: study of ocean atmospheric interactions.
Oceanography began in late 1800's in the oceanographicinstitution in united states. The first organisation was created in 1902 as the "International council" for the "exploration of the sea".
Explanation:

It is the external part of the female genital organs.
It is the birth canal of the female reproductive system.
It is the organ in the female that carries the egg to the uterus.
The vulva is the external part of the female genital organs.
"Offspring grows" is a phrase commonly used to refer to the development of a fetus during pregnancy.
It means that the embryo, which is the early stage of development of the fertilized egg, undergoes a series of cellular divisions and differentiation processes, eventually forming a fully-formed baby.
The growth of the offspring is a complex and highly regulated process that involves many different biological systems and processes, including the placenta, umbilical cord, and various hormones and signaling molecules.
The growth and development of the offspring is a critical aspect of reproduction, and is essential for the continuation of the species.

Chloroplast is the site for photosynthesis in plants. Thus, option A is correct.
Chloroplasts are the cell organelles present in the plants. Chloroplasts are one such type of plastids.
Chloroplasts are green in colour. They contain a green coloured pigment called chlorophyll which traps the solar energy.
The solarenergy is converted into chemicalenergy by a process called photosynthesis. The organic molecules so produced are the energyrich compounds.
Chloroplasts are chiefly found in the mesophyll region of the leaves.
Chloroplast consists of grana and stroma regions. The grana contain disc shaped coin like structures called thylakoids. The matrix of chloroplasts constitutes stroma region.
Various enzymes, DNA, ribosomes etc are found within the chloroplasts. Hence, they are also referred as 'cellwithinthecell'.
Chloroplasts have unique feature of self-replication. Chloroplasts are similar in function to mitochondria in animal cells.
Therefore, chloroplasts are important plant structures for photosynthesis.

In plants, photosynthesis takes place in chloroplasts. Option A is correct.
Plant, algae, and certain protist cells have membrane-bound organelles called chloroplasts.
So, They are in charge of the process known as photosynthesis, which turns light energy into chemical energy in the form of glucose in green plants and some other animals. Life on Earth is supported by this essential mechanism of energy conversion.
Therefore, In plants, photosynthesis takes place in chloroplasts.

Answer:
We can see those planets because there in between the sun and the earth, that's why we can see them, also we can see mars because it is close to earth.
