Biology
1 answer:
Artemon [7]3 years ago
5 0

Answer:

Cellular respiration uses energy in glucose to make ATP. Aerobic (“oxygen-using”) respiration occurs in three stages: glycolysis, the Krebs cycle, and electron transport. In glycolysis, glucose is split into two molecules of pyruvate. ... Life first evolved in the absence of oxygen, and glycolysis does not require oxygen.

When one species of an ecosystem is endangered, other species that interact with or depend on it are never negatively impacted d
Brums [2.3K]
The statement above is FALSE.
When a particular specie in an ecosystem is endangered, other species that interact with it will be negatively affected and the ecosystem may be throw out of balance. This is because all the components of the ecosystem depend on one another for survival.

Describe how is an organism's food and habitat related
Brums [2.3K]
As we already know, organism mean's something that is living.
Well, at a habitat there is going to be some animal's or insect's because it's that animal's or insect's habitat. ( They live there.) Well <u>most</u> organism's are food.
( NOTICE I bloldfaced "most", this is because not all organism's are food) Okay, let's go over what we just said. Organism's are living thing's and habitat's are places where organism's live. Now we have to think about this, you stated, Describe how is an <u>organism's food</u> and habitat related. The one thing we have not talked about is, <u>organism's food</u>. Okay, Animal's live in habitat's and so do organism's.
 ( Remember, some <u>organism's eat other organism's</u>) This is how organism's food and habitat are related.

<u>Hope this help's!</u>
<u>Good luck on your </u>
<u>home work! (:</u>

<span>The gum is probably lodged in the right primary bronchus. The right primary bronchus is an airway directly connected to the right lung. Bronchi are primarily responsible for moving air into the lungs, so when Keri choked on the gum, the gum would have blocked the air passage way required to breathe.</span>

What evidence suggests that RNA appeared before DNA? ribozymes, catalytic RNA, play pivotal roles in modern cells ribosomes are
mote1985 [20]

Answer:

<em>The evidence that suggests  RNA  appeared before DNA is the fact that RNA can act as an enzyme to self-edit their own genetic code. </em>Moreover, it has the ability to store genetic information, while transfer and ribosomal RNA have the ability to translate genetic information into proteins.

Explanation:

RNA has a great capability as a genetic molecule, it once had to carry on hereditary process on its own. It is absolutely sure that RNA was the first molecule of heredity. However, a single stranded RNA is rather unstable and easily damaged by enzymes. By essentially multiplying the existing RNA molecule, and using deoxyribose sugar instead of ribose.

<em>The DNA evolved as a much more stable form to pass genetic information with accuracy.  It shows a biological evolutionary purpose .</em>

Stranded on an island, you have two sources of water to drink: salty ocean water and contaminated fresh water. explain your choi
Liono4ka [1.6K]
I would probably drink a small amount of ocean water in 20 monute intervals, to not over dehydrate myself. This would probably give me enough time to go find other sources of water on the island (eg. coconuts) tp get clean water. In my opinion, this would be a better option than drinking contaminated fresh water. There is a higher risk of getting infected by the bacteria in the water, which would be why its better to take the contaminated fresh water only as a last resort option.

I'm not really sure what I just typed but hopefully it makes some kind of sense to you☺
