What is green house effects?Green house effects are the rays in which heat are taken hold close to earth surface that is near to the earth. These effects have covered the earth like a blanket and keeps the planet toaster and warmer than it could be without them.
Greenhouse gases on Earth trap heat in the atmosphere, warming the whole globe. The primary gases that cause the greenhouse effect are fluorinated gases, as well as naturally occurring gases such carbon dioxide, methane, nitrous oxide, and water vapour which are synthetic.
Thus, option A is correct.

A.Complete Dominance
B. Codominance
C. Incomplete dominance
D. Polygenenic
Answer:
I will give you an explanation, and try to figure it out!!
Explanation:
Incomplete dominance can occur because neither of the two alleles is fully dominant over the other, or because the dominant allele does not fully dominate the recessive allele. This results in a phenotype that is different from both the dominant and recessive alleles, and appears to be a mixture of both.

to assist other lymphocytesto kill cells infected with a virus or cancerto help in the body's immune responseWhat are T-lymphocytes?
T-lymphocytes, also known as T cells, are a type of white blood cell that plays a key role in the immune system. They are produced in the bone marrow and mature in the thymus gland.
One of the main functions of T-lymphocytes is to assist other lymphocytes, such as B cells, in the immune response. They do this by releasing chemicals that help to activate and coordinate the immune response, and by directly attacking infected cells.
T-lymphocytes also have the ability to kill cells that are infected with a virus or cancerous cells. They do this through a process called cell-mediated immunity, in which they recognize and bind to specific proteins on the surface of infected cells. Once they have bound to the infected cells, they release chemicals that kill the cells, helping to prevent the spread of the infection or cancer.
T-lymphocytes are an important part of the body's immune system and play a vital role in helping to protect the body against infections and disease.

Explanation:
TRUE OR FALSE: Phospholipids that are a part of the nuclear envelope (membrane around the nucleus) can easily move from one part of the cell to another, and may ultimately become part of the cell membrane, the ER, a vesicle membrane, etc. In fact, any phospholipid may be called a "cellular tourist" because it is able to move about to virtually any part of a cell and can even become a part of a cell in a different region of the body! (EXPLAIN WHY)
Answer:
False, because phospholipids are a type of lipids and the nuclear envelope contains nucleic acids.
Explanation:
Hope this helps.
It is true that phospholipids that are a part of the nuclear envelope (membrane around the nucleus) can easily move from one part of the cell to another, and may ultimately become part of the cell membrane, the ER, a vesicle membrane, etc.
What is nuclear envelope made of?The nuclear envelope is made up of two concentric lipid bilayer membranes separated by a 20-40 nm intermembranous space.
In many places, the outer membrane is joined to the rough endoplasmic reticulum. The outer membrane of the nuclear envelope, like the rough ER, is dotted with ribosomes.
The nuclear envelope is made up of two membranes: an outer and an inner phospholipid bilayer. The lumen of the rough endoplasmic reticulum is connected to the thin space between the two layers (RER).
Nuclear pores, which are small channels that run across the nuclear envelope, allow substances to enter and exit the nucleus.
Each pore is lined by a group of proteins known as the nuclear pore complex, which regulates which molecules can enter and exit.
Thus, the given statement is true.
