Answer:
The correct answer will be-pachytene, prophase I,
Explanation:
Tetrad is the structure formed during the meiotic type of cell division which produces four daughter cells.
The tetrad structure is seen under the microscope during the pachytene substage of prophase I.
The tetrad structure is formed when four sister chromatids are aligned together in a cell before the crossing over event or recombination has to take place. The tetrad formation allows the crossing over to take place in pachytene.
Thus, pachytene, prophase I is the correct answer.
Answer:
Some animals in the desert don't need to drink water, yet things in the tundra need water
Explanation:
Epithelial tissue covers the body surface and forms the lining for most internal cavities. The major function of epithelial tissue includes protection, secretion, absorption, and filtration.
<u>Explanation:</u>
- Epithelial tissue spreads throughout the body surface covering line body cavities and hollow organs which form the major tissue in the glands. Epithelial tissue covers the outside of the body and lines organs, vessels, and cavities.
- Endothelium joins with the inner tissue lining which covers the brain, lungs, skin, and the heart. It acts as a barrier protecting the body and the environment and maintains the process of protection, filtration, absorption, excretion, and sensation.
- Covering and lining epithelium and the Glandular epithelium which helps in surrounding the glands within the body surface are the characteristics feature in the human body.
The evaluation of their DNA and short tandem repeats will let them know if the birds are related or not. The genetic linkage will provide information about their common ancestry as well as if they belong to the same species, or are closely related species.
The Center for Disease Control and Prevention (CDC) procures the use of safer needle devices such as self-stealthing and self-blunting features of syringes (attached are images of said interventions). In using safer needle devices, 80% of needlestick injuries can be reduced.
