Production has been linked to an increase in the occurrence of skin cancers caused by hole in the ozone layer

Answer: B.CFC

Explanation:

The chlorofluorocarbons or CFCs are the hydrochlorofluorocarbons that are fully or partially halogenated with the chlorine and fluorine as halogen. It is a volatile derivative of methane, propane and ethane.

The fluorides and chlorides reacts with the oxygen present in the ozone layer present in the stratosphere of the atmosphere. This may lead to the disintegration of the ozone layer and results in the formation of a hole. The ozone layer basically function in prevention of incident radiations like UV and infrared coming from the sun. Due to such damage the rays will enter the earth atmosphere and likely to affect the organisms in the biosphere. These radiations are capable of causing instead mutations which may lead to skin cancer.

Behaviors such as stress, exercise, eating patterns, and tension ______ various aspects of the hormonal system.
Olenka [21]

Answer:

Activates or suppresses

Explanation:

The hormonal system or the endocrine system involves chemical systems where feedback loops of hormones are released directly into the circulatory system by internal glands.

It involves the interaction between the hypothalamus, pituitary glands and sex glands.

Release of hormones is dependent of signalling therefore behaviors such as stress, eating patterns and tension can activate or suppress various aspects of the hormonal system.

During conjugation, one gene (A) is found to transfer to the recipient bacteria 26 minutes following the start of conjugation, w
AnnyKZ [126]

Answer:

a. All of the answers are correct.

Explanation:

During conjugation a bacteria transfers it's genetic material to another bacteria. The genetic material has genes in a particular order so we can easily know the order of the genes through experimentation. The transfer of genes occurs as per the time allowed. If two genes are nearby then they will be transferred one after the other.

For example in the given question, gene A was transferred to recipient bacteria in 26 minutes, gene M was transferred in 37 minutes while gene T was transferred in 45 minutes, it simply means that the order of genes is A M T. Gene M was transferred to another bacteria after A was transferred because time required to transfer it is 37 minutes which is less than time required to transfer A which is 26 minutes. Gene T took maximum time to get transferred so it will be last to be transferred.

After calculation, we can easily infer that the genetic distance between A and M is 11 minutes (37 minutes - 26 minutes = 11 minutes). Similarly we can get genetic distance between A and T as 19 minutes and between M and T as 8 minutes. So all the given options are correct.

Mice21 [21]

Answer:

I. Adaptation.

II. Filiform papilla.

III. Gustation.

IV. Bowman's gland.

V. Basal cell.

VI. Vallate papilla.

VII. Olfactory.

VIII. Sustentacular cell.

IX. Cranial nerve I.

X. Cranial nerve VII.

Explanation:

A sensory system can be defined as components of the central nervous system (CNS) which comprises of the brain, neural tissues or pathways and sensory neurons responsible for sensory functions, perception and processing sensory informations such as sound, light, heat, etc.

Generally, the nervous system found in living organisms such as humans, comprises of two (2) major components or systems; a central nervous system (CNS) and a peripheral nervous system (PNS).

Basically, the central nervous system (CNS) interprete the neural signals that are generated from stimuli that are detected by the sensory system. The five (5) main sense organs in the sensory system are: skin, tongue, ears, nose and the eyes. Some of the terminologies and features associated with the sensory system includes the following;

I. Adaptation: loss of sensitivity due to repeated stimuli. Stimulus can be defined as an obvious change in either the chemical or physical structure of an organism' environment (either external or internal).

II. Filiform papilla: helps manipulate food on tongue surface. These are the thread-like dots found on the tongue and they typically cover two-third (⅔) of the human tongue.

III. Gustation: sense of taste. It is the ability of a living organism to taste flavors in a food or other things.

IV. Bowman's gland: produces mucus. It's a nasal gland found in the olfactory mucosa and responsible for the production of mucus in living organisms.

V. Basal cell: stem cell of olfactory receptor.

VI. Vallate papilla: contains taste buds for bitter substances.

VII. Olfactory: sense of smell. This is the ability of a living organism to perceive or smell something.

VIII. Sustentacular cell: supportive cell of olfactory receptor.

IX. Cranial nerve I: cranial nerve for taste.

X. Cranial nerve VII: cranial nerve for smell.
