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.

Answer:
A. A computer
Explanation:
The way your nervous system works can be compared to how your computer works. When you press the power on your computer, a signal goes out. The signal is a catalyst that generates a number of actions and responses. An electric current travels over the wires maintaining a connection to electricity
The nervous system may be compared to a computer. So, the correct option is A.
What is Nervous system?The nervous system is defined as a highly complex part of an animal that coordinates its functions and sensory information through the transmitting signals from different parts of its body. This system includes
1. The central nervous system consists of the brain and spinal cord)
2. The peripheral nervous system consists of the nerves that extend from the spinal cord to the rest of the body
3. Other nerve tissue.
The nervous system may be compared to a computer. The way our nervous system works can be compared to the way your computer works. When we press power on computer a signal comes out like CNS and PNS work in the body

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.

The monarch butterfly and the queen butterfly have to compete for the same food source . This is an example of____competition.
A. Co-species
B. Intraspecies
C. Interspecies
D. Habitat
Answer:
B.
Explanation:
In an ecological environment living things of different or same species compete with each other for the limited resources available. It is a symbiotic interaction between these living things.
There are two types of competition between these living beings- intraspecific and interspecific. In the given scenario, it is an intraspecific competition between the monarch butterfly and the queen butterfly.
Intraspecific competition is a competition between two living beings of the same species.
The monarch butterfly and the queen butterfly both belong to the same species- danaus.
Therefore, option B is correct.
A cylindrical tin full of engine oil has a diameter of 12cm and a height of 14cm.The oil is poured into a rectangular tin 16cm long and 11cm wide. What is the depth of the oil in the tin?
Answer:
Depth = 9 cm
Explanation:
First, calculate the volume of the cylindrical tin.
Mathematically, that would be the following:
[tex]V = \pi * r^{2} * h[/tex]
Now, r = d/2 = 12/2 = 6 cm
h = 9 cm
Therefore, the volume will be:
V = 22/7 * 14 * 6^2 =1,584 cm^3
Now, to find the the depth of the tin, we have to realize that the content of the cylinder should fill in the tin to a particular height.
As we don't have the height of the tin so let's suppose it x, now it means that
l * b * h = 16 * 11 * x = 176x
Therefore, the depth would be:
176x = 1584
x = 1584 / 176 = 9 cm

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.
