Correct Answer: epithelial
Explanation:
Epithelial tissue is made of layers of cells that cover the surfaces of the body that come into contact with the exterior world, line internal cavities, and form glands.
The four types of tissue in the body are epithelial, connective, muscle, and nervous.
Correct Answer: Uracil
Correct Answer: protists have a membrane-bounded nucleus, which bacterial cells lack.
Correct Answer: phagocytosis
Correct Answer: 5 - 63 deg
Explanation:
The temperature danger zone for the food that cannot be stored for long time is between 5 degrees to 63 degrees centigrade.
Correct Answer: A DNA is made up of four bases called Adenine, Thymine, Cytosine and Guanine
Correct Answer: Both A & B
Explanation:
Osteoporosis makes you more likely to loss bone mass and density resulting in fractures. Smoking cigarettes and drinking alcohol can lead to loss bone mass and density. Oseoporosis is more common in women than men.
Correct Answer: Both A & B

2. Enveloped viruses bud from the host cell.
3. HIV contains reverse transcriptase.
4. A retrovirus contains RNA.
Correct Answer: more HDL

Hence, when it comes to cholesterol it is better to have more HDL.
Correct Answer: Both A & B
