Answer:

To study these moths, Dr. Kettlewell placed light and dark moths on the trunks of trees where he could observe them. The same birds would find the dark moth twice as often if the bark on the tree was light. This supported the idea that dark moths had a survival advantage in a dark forest.

Answer:

B. sensorineural hearing loss

Explanation:

Damage to these hair cells results in decreased hearing sensitivity, and because the inner ear hair cells cannot regenerate, this damage is permanent.

Damage to the auditory nerve or to the hair cells in the inner ear results in sensorineural hearing loss. Thus, the correct option is B.

The auditory nerve may be defined as a cluster of nerve fibers that transport hearing information between the cochlea and the brain.

When the auditory nerve or hair cells are damaged due to any injury or other reasons, it can lead to a reduction in hearing sensitivity.

The cells of this region are unable to regenerate, and hence this damage will remain permanent, and sensorineural hearing loss will result in this scenario.

Therefore, the correct option for this question is B.

Cell theory

Explanation:

The unified cell theory states that: all living things are composed of one or more cells; the cell is the basic unit of life; and new cells arise from existing cells.

Answer:

It involves facilitated diffusion.

Explanation:

Facilitated diffusion uses channel proteins. Channel proteins allow substances to travel through a membrane going with the gradient. Since active transport goes against the gradient, facilitated diffusion would not be a characteristic of it.

The condition that is caused by carbon dioxide, methane, and water vapor trapping heat in the Earth's atmosphere is known as the greenhouse effect. Thus, the correct option is B.

The earth's atmosphere may be defined as the significant presence of a layer of various gases that surrounds the whole planet. It is known that the Earth's atmosphere is composed of about 78% nitrogen, 21% oxygen, and one percent other gases.

Carbon dioxide, methane, and water vapor are considered greenhouse gases that ultimately capture the heat radiations from the sun and liberate the earth's atmosphere. As a result of this, the average temperature of the earth's surface has gradually increased for four to five decades.

This is all known as the greenhouse effect. The Greenhouse effect may be defined as the phenomenon of keeping the earth warm due to the presence of certain gases in the atmosphere that captures heat from the sun.

Therefore, the condition that is caused by carbon dioxide, methane, and water vapor trapping heat in the Earth's atmosphere is known as the greenhouse effect. Thus, the correct option is B.

Answer: Water retains its temperature for long.

Explanation:

The ice floats on the water of river as it is less denser then the liquid water. This causes ice to float on water. It protects the water at the bottom from freezing. The decrease in the temperature level can cause the death of the marine life by catching organisms in the ice. The floating of the ice insulates the water present beneath. So, the fish and other aquatic animals can survive and the fishermen can catch the fishes alive.

Changing the shape or morphology of the mitochondrial inner membrane can change the efficiency of mitochondrial function.

Which of the following outcomes will most likely result from a change in the shape of the mitochondrial inner membrane from a highly folded surface to a smooth, flat surface?

A. Mitochondria will become more efficient because the inner mitochondrial membrane will become more permeable to ions.

B. Mitochondria will become more efficient because the total volume of the mitochondria will increase.

C. Mitochondria will become less efficient because the inner mitochondrial membrane will become less permeable to large molecules.

D. Mitochondria will become less efficient because the surface area of the inner mitochondrial membranes will decrease.

Answer:  D. Mitochondria will become less efficient because the surface area of the inner mitochondrial membranes will decrease.

Explanation:

Mitochondria is called the power house of the cell as it produces energy by the oxidation of food in the form of adenosine triphosphate or ATP. The inner mitochondrial membrane comprises of numerous folds which are called cristae which increases the surface area for the chemical reactions necessary for the production of energy. If the folding increases the surface area for  energy production will decrease as the surface area for chemical reactions will decrease. Thus the efficiency of mitochondria will decrease.

If the mitochondrial inner membrane becomes flat or smooth surface then this also decreases the surface area for chemical respiration, thus in this case too the efficiency of mitochondria will decrease.

The weather that is averaged over a long period of time is the climate that is present in Option C because climate is a prolonged period of weather that is taken into consideration, and the regions are specified for the climatic condition.

Weather is affected by various factors, such as temperature, humidity, etc., and that is not permanent for years, but it is temporary because when there is a rainy day, the weather condition of that place is more cold, while in a place where there is a high temperature, the weather becomes dry for that region. Climate is a weather condition that lasts for long periods of time, such as 20 or 30 years, and depending upon the climate, different ecosystems are considered.

Hence, the weather that is averaged over a long period of time is the climate that is present in Option C because climate is a prolonged period of weather that is taken into consideration, and the regions are specified for the climatic condition.

Cellular division

Explanation:

it's because abnormal production (mutations) causes leukemia

cellular division is most likely affected by this new drug in case of leukemia. Thus option D is correct.

Leukemia is a cancer related abnormal division in blood or blood-forming cells. It is other wise known as blood cancer.

The exact cause is not known, major risk factors are radiation exposure, chemotherapy for cancer, smoking, family history of leukemia, and exposure benzene.

Leukemia cells, do not clump to form tumor, due to this  leukemia is not diagnosed through imaging tests.

Common symptoms include pain in the bones, swollen lymph,, bleeding and bruising  nodes, feeling weak, fevers or night sweats etc.

Leukemias can be acute or chronic.

On the basis of cell type affected  four types of leukemia observed such as acute lymphoblastic leukemia (ALL), chronic lymphocytic leukemia (CLL), acute myelocytic leukemia (AML), and chronic myelocytic leukemia (CML).

The correct answer is -a  common characteristic (in a logical manner)

Explanation:

The six kingdom classification is given by Woese et al 1977, the basis of this classification was the shared characteristic of organisms. These common characteristics include more than one character such as cell type ( prokaryotic or eukaryotic), type of nutrients (autotrophs, heterotrophs), type of reproduction, homologous or analogous organs, habitat, and many more.

All these traits or characters helped in grouping organisms in a logical manner and is one of the most acceptable classifications.

Cells divide and reproduce in two ways, mitosis and meiosis. Mitosis results in two identical daughter cells, whereas meiosis results in four sex cells.

Answer:

1. meiosis require two nuclear division but mitosis requires only one nuclear division  

2. meiosis produces four daughter divisions, and there are four daughters cell following cytokinesis. Mitosis followed by cytokinesis result in two daughter cells  

3. in meiosis, the four daughter cells are haploid and have half the chromosome number as the parent cell. In mitosis, the daughter cell have the same chromosome number as the parent cell  

4. in meiosis the daughter are genetically dissimilar to each other and to parent but in mitosis, the daughter cells are genetically identical to each other and to the parent.
