Answer:
D
Explanation:
Nucleus contains all the genetic material that codes for different proteins that control the cell's actions. It's surrounded by a nuclear membrane.
However,
- Mitochondria is used for energy production and isn't surrounded by a nuclear membrane. It's in fact surrounded by 2 membranes.
- Pinocytic vesicles usually contain endocytosed material from outside that has nothing to do with the cell's control.
- Nucleolus is inside the nucleus and is used to make rRNA needed for ribosomes production. A nucleolus is not surrounded by any membrane.
The method of the following issues that cause homeostatic imbalances:
1. Gallstones: The precipitation of excess bladder cholesterol into solid crystals is a prerequisite for cholesterol bladder formation, which is caused by disturbed bladder homeostasis. ... We have previously seen that bile and bladder osteopontin (OPN) levels are decreased in gallbladder patients.
2. Ulcers: Gastric bleeding is a major complication of peptic ulcer. Infection by H. Pylori leads to an imbalance of body iron homeostasis, as the increasing demand for iron is the same. Like other types of bacteria, iron is also essential for H growth.
3. Dehydration: If we are low on water, our bodies reduce the sweat and urine we produce to reduce fluid. Most of these reactions are effective under normal conditions and can restore water levels to homeostasis.
4. Diarrhoea: Bile acids, bacterial enterotoxins and neoplasm-derived secrets disrupt this homeostatic state, for example, leading to diarrhea. ... Different infectious organisms (eg bacteria, protozoa, viruses) use different mechanisms to cause intestinal infection and dysentery.
5. Cirrhosis: Disturbed volume homeostasis in patients with cirrhosis of the liver. ... Patients with moderately developed cirrhosis often show a characteristic circulatory disturbance, including arterial hypotension and urinary sodium retention by the kidney, which may lead to edema and ascites.
6. Cancer: Cancer, in this example, breaks down in the balance between cell growth and cell death. The gene that over-expresses anti-apoptotic genes and rejects pro-apoptotic genes is not understood, and it is often unknown why homeostatic equilibrium is lost (perhaps another term for carcinogenesis).
Answer:
The correct answer is Active transport moves substances against the concentration gradient.
Explanation:
The principle difference between active transport and facilitated diffusion is that active transport helps in the movement of various substances in the uphill direction which means against the concentration gradient.
In simple words active transport helps in the movement of substance from the region of low concentration to a region of high concentration.
On the other hand during facilitated diffusion substances move along their concentration gradient which means from the high concentration region to the region of low concentration until the concentration of both sides become same.
Answer:
All Natural Resources fall under two main categories: Renewable and Non-renewable Resources. ... Non-renewable resources are those that cannot easily be replaced once they are destroyed.

Answer:
Psychoanalytic, trait, humanistic, and social cognitive theories.
Explanation:
Psychoanalytic, trait, humanistic, and social cognitive theories are the four main theories of personality. These theories of personality provides information about the changes that occurs in the personality of an individual. Psychoanalytic personality that guides psychoanalysis which is a clinical method for treating psychopathology.
