Which of the following describes only RNA?

The experiment carried out by Avery, MacLeod, and McCarty in 1944 established that DNA is the genetic material that carries genetic information. This experiment was conducted on the bacterium Streptococcus pneumoniae, which is a pathogen that causes pneumonia in humans.

This bacterium can exist in two forms, a rough strain and a smooth strain. The S strain is surrounded by a polysaccharide capsule, while the R strain does not have a capsule. When mice were injected with the S strain, they developed pneumonia and died.

On the other hand, the mice injected with the R strain were healthy.The researchers used enzymes to degrade proteins, RNA, and DNA from the heat-killed S strain. They then added the three enzymes to the living R strain and found that the transformation still occurred, indicating that none of the enzymes destroyed the transforming ability.

They then repeated the experiment with different enzyme combinations and found that when DNase was added to the living R strain, the transformation did not occur. This finding led them to conclude that DNA is the genetic material that carries genetic information.

Therefore, the fact that the transforming capacity of the IIIS cell extract was not abolished by treatment with RNase proves that RNA does not function as the genetic material in the IIIS cells (Diplococcus pneumoniae). Hence, option (D) is the correct answer.

This experiment provided important evidence that DNA is the genetic material that carries genetic information and paved the way for future genetic research.

Hypersecretion of thyroxine in the thyroid gland results in suppression of TSH (thyroid-stimulating hormone) from the pituitary gland.

Hyposecretion of cortisol in the adrenal glands results in an increase in the secretion of ACTH (adrenocorticotropic hormone) from the anterior pituitary gland.

Adrenocorticotropic hormone (ACTH) is a hormone produced and secreted by the anterior pituitary gland in the brain. Its primary function is to stimulate the production and release of cortisol, a steroid hormone, from the adrenal cortex, which is the outer layer of the adrenal glands located above the kidneys.

ACTH is released in response to stress, low blood sugar levels, and other factors that signal the need for increased cortisol levels in the body. It acts on the adrenal cortex to increase the synthesis and release of cortisol into the bloodstream, which then helps the body cope with stress, regulate blood sugar levels, and maintain normal immune function.

By eating plants

Explanation:

The plants uptake the nitrogen by the help of the nitrogen fixing bacteria found in the soil. The nitrogen from the plants is taken by the animals eating the plants. The source of the nitrogen to the animals is the plants containing nitrogen. The plants are also supplied with some of the fertilizers that contains adequate amount of nitrogen in it, which is transferred to the animals when they eat it.

The example of antagonistic hormones controlling homeostasis is insulin and glucagon in glucose metabolism.Homeostasis is the state of relative stability in the body's internal environment. It requires maintaining a balance between the variables of an organism's internal environment, such as temperature and fluids.
Hormones play an essential role in the body's regulatory mechanisms, including homeostasis.Antagonistic hormones, such as insulin and glucagon in glucose metabolism, have opposing effects on the body. Insulin, which is produced in the pancreas, decreases blood glucose levels, while glucagon, also produced in the pancreas, increases blood glucose levels. These hormones maintain the body's blood glucose level within a narrow range.Insulin and glucagon are antagonistic hormones that maintain glucose homeostasis. When glucose levels rise, insulin is released from the pancreas to reduce glucose levels. When glucose levels are low, the pancreas releases glucagon to raise glucose levels. Therefore, antagonistic hormones, such as insulin and glucagon, work together to control homeostasis.

A ball and socket joint, also known as a spheroid joint, is a type of joint found in the human body that allows for a wide range of movement. It is composed of a ball-shaped bone (the head of the bone) that fits into a socket-shaped bone (the acetabulum). One example of a ball and socket joint in the human body is the hip joint. The head of the thigh bone (femur) is the ball, and the acetabulum of the pelvis is the socket.

This kind of joint allows for movement in multiple planes, such as flexion and extension, abduction and adduction, and internal and external rotation.

Another example of a ball and socket joint is the shoulder joint. The head of the upper arm bone (humerus) forms the ball, and the socket is formed by the glenoid cavity of the scapula. This joint allows for a wide range of movement, including elevation, depression, protraction and retraction and internal and external rotation.

Ball and socket joint are synovial joints which are the most mobile type of joints in the human body. They are essential for activities of daily living such as walking, running, and reaching for objects. However, due to its great range of motion, ball and socket joints are also more prone to injuries such as dislocations and sprains.

The mechanism causes the movement of phloem sap from sources to sink tissues that would be differences in the source-sink pressure potential according to the pressure-flow hypothesis.

As a result of the high turgor pressure, phloem sap is transported by "bulk flow" from the source to the sink, where the sugars are quickly eliminated from the phloem. The rise when the sugar is removed, causes the water to leave the phloem and return to the xylem, lowering the p.

Phloem sap moves through phloem via translocation, the transport of dissolved materials in a plant, which is triggered by high turgor pressure and occurs from source to sink. Phloem carries sap both upward and downward, from sugar sources to sugar sinks, unlike the xylem, which can only carry water upward. It is suggested that the phloem is a conduit through which pressure-containing water-carrying food molecules flow.

Essential amino acids are amino acids that cannot be synthesized by the body and must be obtained from the diet.

The human body requires a total of twenty amino acids to synthesize proteins, and these can be sourced from the food we consume. Among the twenty amino acids, nine are classified as essential, while the remaining eleven are considered non-essential. While the body can produce non-essential amino acids, it lacks the ability to synthesize essential amino acids. Hence, it is crucial to acquire them through dietary sources or supplementation.

Contrary to the statement, essential amino acids are not the only ones needed by the body. Non-essential amino acids also play a vital role in the synthesis of proteins, enzymes, and various other biological molecules. Additionally, both essential and non-essential amino acids contain nitrogen, debunking the claim that essential amino acids are the sole nitrogen-containing components.
