What is NOT a function of the
nucleus?
A. Directs protein synthesis
B. Houses DNA
C. Functions as the powerhouse of the cell
Answer:
function as the powerhouse of cell
Explanation:
we have read the power house of cell as a mitochondria
==========================================================
Explanation:
The mitochondria is responsible for generating the cell's energy, hence the phrasing "the mitochondria is the powerhouse of the cell".
The nucleus holds the DNA, so we can rule out choice B. The DNA in turn is connected to forming the proteins. The actual protein synthesis happens in the ribosomes, but the DNA is used as a blueprint (more or less) to assemble the correct amino acids in the correct order to form the complicated protein chains. In short, the nucleus indirectly helps direct the protein synthesis, so we can rule out choice A.

Why has the demand to find more than fossil fuels for energy increased?
Explanation:
Global energy demand is increasing due to industrial activity and advances in both developing and developed countries. ... The GHGs from geothermal energy systems for electrical power production and space heating applications are much lower than those from conventional fossil fuel energy systems [3,4].
Answer:
Explanation:
The demand for energy across the world is constantly rising. This increased demand is caused in part by the increase in population, and by economic development. It is because these areas experienced large-scale economic development, their original energy sources were fossil fuels – first coal and oil and gas.

2. The structure of the inner core iron and nickel.
3.Earth's outer core is a fluid layer about 2,400 km (1,500 mi) thick and composed of mostly iron and nickel that lies above Earth's solid inner core and below its mantle.
4.In terms of its constituent elements, the mantle is made up of 44.8% oxygen, 21.5% silicon, and 22.8% magnesium. There's also iron, aluminum, calcium, sodium, and potassium. These elements are all bound together in the form of silicate rocks, all of which take the form of oxides.
5.The asthenosphere is now thought to play a critical role in the movement of plates across the face of Earth's surface.

Based on this information, this technique is an example of selective breeding, which is a reproduction control and management technique.
What is selective breeding?It implies a manipulation of the characteristics that are inherited, that is, it is a technique that consists of choosing the phenotypes of the organisms that are cultivated or bred.
This peculiarity allows guiding the evolution of the species according to the needs of the human being to have specimens with the desired characteristics in a stable manner.
Therefore, we can conclude that based on this information, this technique is an example of selective breeding, which is a reproduction control and management technique.

Phosphorylation of ADP to ATP occurs
A. via ribosomes on the endoplasmic reticulum.
B. in the nucleus
C. in the mitochondria
D. within the cell membrane
Answer:
C. in the mitochondria
Explanation:
Mitochondrial ADP/ATP carriers transport ADP into the mitochondrial matrix for ATP synthesis, and ATP out to fuel the cell, by cycling between cytoplasmic-open and matrix-open states. ... Because these features are highly conserved, this mechanism is likely to apply to the whole mitochondrial carrier family.
Answer:
C. in the mitochondria
Explanation:
Phosphorylation of ADP to ATP occurs in the mitochondria.

Answer:
Secondary consumer level = 900 kcal of energy
Producer level = 90000 Kcal of energy
Explanation:
According to this question, there are 9000 kilocalories of energy available at the primary consumer level. Since, only about 10% of energy is transferred from one trophic level to another in a food chain, the following will be available at the secondary consumer and producer level;
Note that:
Producer → primary consumer → secondary consumer
* At the producer level; where x is the amount of energy available at the producer level.
10/100 × x = 9000kcal
10x/100 = 9000
10x = 900000
x = 900000 ÷ 10
x = 90,000 Kcal of energy.
* At the secondary consumer level:
10/100 × 9000
90000/100
= 900 Kcal of energy.
