<u>ANSWER:</u>
The correct order is- Zygote, Blastula, Gastrula, Fetus.
<u>EXPLANATION:</u>
- The embryo develops from the zygote which is formed when the gametes fuse in the process of "fertilization".
- The zygote undergoes cell division to form blastula which is a "ball of cells".
- Gastrula leads to the rearrangement of cells of the blastula into three layers that differentiate into different systems of organ.
- The last stage is the fetus which then develops into a baby.
The correct option is "D", "<span>The density of seawater".
As you are measuring the</span><span> amount of mass in a volume of water and if we look at the definition of density, it is the mass per unit volume.
D = m/v
where m is the mass of an object and v is the volume.
Thus, d is the correct option.</span>
Answer and Explanation:
Cytokines is the molecule which has the ability to communicate with the immune system cells to target on antigen by generating a response. It is mostly comprised of protein in a group along with peptides.
They are involved in the cancer treatment by production of the signalling molecules that gets involved in the method of stimulating and mobilize the immune system and thus cytokines come into the action for preventing the cancer by providing anti-inflammatory action,anti-cancer cell etc.
<u>Example</u>- In case of ovarian cancer,there is the majority of the immuno-suppressive action and thus there is production of the anti-inflammatory cytokines and thus maintain the immune system.
