Some cells, such as human nerve and muscle cells contain many more mitochondria than do cells such as skin cells why do some cells have more mitochondria than others
A. The cells use more energy
B. The cells store more nutrients
C. The cells degrade more protein
D. The cells divide more frequently
Answer:
A
Explanation:
different types of cells use different amounts of energy
Some cells, such as human nerve and muscle cells contain many more mitochondria than do cells such as skin cells, some cells have more mitochondria than others as they use more energy. Thus option A is correct.
What are the characteristic feature of mitochondria ?
Mitochondria is commonly called as the “Powerhouse of the cell, these are double membrane-bound organelle present in most eukaryotic organisms located in cytoplasm and function as cell's “digestive system.”
They involve in break down of nutrients and generate energy-rich molecules, cellular respiration occur within the mitochondria, was first described by a German pathologist named Richard Altmann in the year 1890.
The mitochondrion is rod-shaped structure found in both plant and animal cell, size ranges from 0.5 to 1.0 micrometre in diameter, consist outer membrane, an inner membrane, and a gel-like matrix.
The outer and inner membrane are composed of proteins and phospholipid layers which is separated by the intermembrane space.

______ plants are important in fixing nitrogen.
a. Legume
b. Berry
c. Nut
d. Poisonous
Answer:
A
Explanation:
Legume plants are important in fixing nitrogen. Therefore, the correct option is A.
Beans, peas, lentils and clover are examples of leguminous plants that are important for nitrogen fixation. They co-exist well with rhizobia, a type of bacteria that fix nitrogen. These bacteria live in nodules on the roots of legumes and use a process called nitrogen fixation to convert atmospheric nitrogen into a form that plants can use.
Legumes can obtain substantial amounts of nitrogen, an important nutrient for plant growth, without being entirely dependent on soil nitrogen, because of their ability to fix nitrogen. Legumes play an important role in agriculture and ecosystems, by adding nitrogen to the soil and increasing its fertility. Legumes are valuable crops because of their high protein content as well as their ability to improve soil health by fixing nitrogen.
Therefore, the correct option is A.

Based on the Resource Use and Conservation Virtual Lab, Which tactic can do the most to keep the water debt less than the water supply?
A. Outlawing water features in gardens
B. Replacing drip irrigation systems
C. Outlawing drip irrigation systems
D. Replacing thermal power plants.
Answer: D. Replacing thermal power plants.
Explanation:
Thermal Power Stations are some of the biggest users of water in the world because water is integral to producing electricity in them. These stations burn fossil fuels like coal which then vaporizes water so that it becomes steam which then drives turbines that produce electricity.
Water is also used for cooling high temperatures produced.
If these thermal stations are replaced with something that uses less water, it will go a long way in keeping the water debt less than the water supply.

When chromosomes do not separate you end up with a
gamete with to many or to few chromosomes. This is known
as...
Answer:
The phenomenon of unequal separation in meiosis is called nondisjunction. If nondisjunction causes a missing chromosome in a haploid gamete, the diploid zygote it forms with another gamete will contain only one copy of that chromosome from the other parent, a condition known as monosomy. I think sorry if wrong ;)

Describe the relationship between genes, proteins, chromosomes, and cells.
Answer:
Genes are segments of deoxyribonucleic acid (DNA) that contain the code for a specific protein that functions in one or more types of cells in the body. Chromosomes are structures within cells that contain a person's genes. Genes are contained in chromosomes, which are in the cell nucleus.

Genes are segments of DNA that contain the code for a specific protein that functions in one or more types of cells in the body. Chromosomes are structures within cells that contain a person's genes. Genes are contained in chromosomes, which are in the cell nucleus.
What are chromosomes?Chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA). Passed from parents to offspring, DNA contains the specific instructions that make each type of living creature unique.
The term chromosome comes from the Greek words for colour (chroma) and body (soma). Scientists gave this name to chromosomes because they are cell structures, or bodies, that are strongly stained by some colourful dyes used in research. The unique structure of chromosomes keeps DNA tightly wrapped around spool-like proteins, called histones.
Without such packaging, DNA molecules would be too long to fit inside cells.

The cell cycle has a regular system of checks and balances that prevents damaged or mutated cells from proceeding to the next phase. One way an organism deals with the problems is to kill the damaged cell before it passes on the problem to its daughter cells. This is a normal process called apoptosis.
a. True
b. Fale
Answer:
A. True
Explanation:
Apoptosis is a normal cellular process in which the cell inherently programs the death of a mutated or damaged cell without affecting the healthy condition of the other surrounding cells by proliferating.
Apoptosis is a system of checks and balances that the cell uses to prevent damaged or mutated cells from proceeding to the next phase in the cell cycle. This curbs or prevent the damaged cell from passing on the problem to its daughter cells. Hence, according to this question, it is TRUE.

Answer:
This question is incomplete as it lacks options, the options are:
A) a single variable
B) multiple variables
C) the hypothesis
D) scientific observations
The answer is A
Explanation:
An experiment is conducted to solve a particular problem or find answers to a given scientific question. In an experiment, which usually consists of variables, only A SINGLE VARIABLE is tested at once.
This means that the effect of a variable called INDEPENDENT VARIABLE is tested at a time. The independent variable is the variable that is changed or manipulated in an experiment. This means that only a SINGLE VARIABLE can be changed at at time in an an appropriate design experiment.
