Which traits are characteristic of single-celled organisms?

Biology
1 answer:
omeli [17]4 years ago
4 0
B and C)
They often obtain most of their nutrients through the cell membrane as diffusion is able to take place passively and so at no energy loss to the organism, this can be essential for a single celled organism as they are able to produce a lot less energy due to having fewer mitochondria in comparison to multicellular organisms. 
They also require few resources as single celled organisms are very small and so require only a small amount of raw resources for respiration because they have a small energy demand to meet.

What would happen if the moon was twice as fast as it it now
r-ruslan [8.4K]

Ans ; It would have to be closer for it to be in a circular orbit twice as fast. One moon cycle would be 2 weeks instead of 4 so our months would have been based on 2 week cycles making for 24 months. Tides would be less synchronous between days and much more intense because of how close it would be. This would have left a very different land map. Tidal forces would force the moon to rip apart sooner than with it's present orbit creating an important ring system around earth earlier.

The remains of living organisms are compressed and stuck together over time to form a rock. What type of rock is it?
inn [45]

Dead organisms when get compressed and stuck together inside soil for long time, gives rise to organic sedimentary rocks.

Option D

<u>Explanation:</u>

Organic sedimentary rocks are the types of sedimentary rocks generally formed in swamps or water logged areas over years where remains of living organisms like leaf or dead bodies of animals get petrified and stored under the soil for considerable amount of time and due to carbon deposition, it forms rocks. Most classical example of this type of sedimentary rocks is coal.

When a dead organism gets stuck and dies, firstly the body gets petrified. Then the minerals from surrounding soil and from the body itself gets to deposit in that place and slowly with time, it forms the rock.

the human is able regulate blood sugar levels within a fairly specific range, even high amounts of carbohydrates are consumed
Stells [14]

Question options:

1. Homeostasis

2. Digestion

3. Embryology

4. Cellular respiration

Answer:

<u>1. Homeostasis</u>

Explanation:

Sugar level in humans is regulated by "Insulin" and "glucagon" hormones that are secreted by the pancreas. Both hormones work in a balanced way to regulate the blood sugar level within a specific range if the sugar levels spike or drop.

Together,<u> </u><em><u>insulin and glucagon help maintain a state known as homeostasis</u></em><em>.</em> By definition, homeostasis is the maintenance of the internal environment of cell/body with respect to the external environment. Thus, homeostasis maintains a relatively stable state that persists despite changes in the world outside.<u> When blood sugar is too high, the pancreas secretes more insulin which acts to trigger breakdown of sugar thus reducing its level. By contrast, when blood sugar levels drop, the pancreas releases glucagon to allow conversion of macromolecules to simple sugars and raise its level.</u>
