Answer:
1.yes
2.yes
3. if we don't interact with sharks they might not interact with us as often
Explanation:
With Personal Watercraft having no brakes, the best thing to
do in avoiding obstacles is to take caution and slow down while operating the
Personal Watercraft boat but when obstacles are ahead and you need to use
methods, it is best to apply throttle and after that, steer quickly.
Answer:
b. Mutations that inactivate tumor suppressor genes are important in cancer.
Explanation:
Most cancers have inactivating mutations in one or more proteins that normally,Cancer can result from expression of mutant forms of these proteins: growth factors and mutation in only one of the two alleles is sufficient for induction of cancer, the cells from tumors caused by these viruses is near the c-myc gene.
Answer:
a. glycolysis—preparatory reaction--cirtric acid cycle--electron transport system
Explanation:
- Glycolysis is the first stage of cellular respiration that occurs in the cytoplasm of the cell. During glycolysis one 6 carbon glucose is converted into two molecules of 3 carbon pyruvic acid or pyruvate.
- In the preparatory reaction, the pyruvate converted into a two-carbon molecule called acetyl CoA. In this reaction, a carbon dioxide molecule is released and a molecule of NADH is released.
- The citric acid cycle begins with the reaction of the acetyl CoA with a four-carbon molecule in the mitochondrisl matrix. It goes through a cycle of reactions regenerating the four-carbon starting molecule. ATP, NADH and FADH₂ are produced.
- The electron transport system is the terminal step of aerobic respiration that operates on the inner membrane of the mitochondria. Reduced coenzymes NADH and FADH₂ move along electron transport system release high-energy electrons and produce ATP.
Answer: Mars receives more insolation than Saturn.
Explanation:
Insolation is defined as the exposure to the Sun's rays.
Mars is the 4th planet in Our solar system and is near to the Sun.
Saturn is the 6th-planet in Our solar system and is far from the Sun.
Insolation is directly proportional to the planet's distance from the Sun.
So, the exposure of Sun's rays is more to the planet which lie close to the Sun.
As, Mars is close to the sun than Saturn. Hence, it will receive more insolation than Saturn.
