What is RNA?

RNA (ribonucleic acid) is a type of biological molecule that is essential for various biological processes in living cells. It is a nucleic acid, just like DNA, but it is usually single-stranded (while DNA is usually double-stranded) and it contains the sugar ribose instead of deoxyribose. RNA plays a central role in gene expression, serving as a template for the synthesis of proteins.

mRNA (messenger RNA) is usually single-stranded. It is synthesized as a complementary copy of one of the DNA strands during transcription, and then carries the genetic information from the DNA in the nucleus to the ribosomes in the cytoplasm, where it is used as a template for protein synthesis.

The structures that keep sweat out of the eyes, aid in nonverbal communication, and enhance facial expression are called "eyebrows" and "eyelashes".


Eyebrows are the thin, arched patches of hair above the eyes. They serve to keep sweat, rain, and other debris from falling into the eyes by diverting them to the sides. They also play a role in nonverbal communication, as they can be raised or lowered to express emotions such as surprise, anger, or confusion.

Eyelashes are the short hairs that grow along the edges of the eyelids. Their main function is to act as a protective barrier for the eyes. They help to filter out dust, dirt, and other particles from entering the eyes. In addition, they also play a role in nonverbal communication, as blinking or fluttering the eyelashes can convey various messages or emotions.

It called when neurons communicate with each other is synaptic transmission

The nervous system is a complex system that plays a role in regulating and coordinating all body activities. This system consists of neurons that receive stimuli from various organs. Stimuli that come from outside or inside the body such as heat, cold, or hunger will be received by the receptors and passed on to the central nervous system.

The neuron is the structural and functional unit of the nervous system consisting of the nerve cell body, nerve fibers and their sheaths.  At the end of the neuron there are synaptic buttons that function to transmit stimuli. It is at the synapses that communication between neurons occurs. The postsynapsis will receive stimuli to be delivered to the postsynaptic cell.

The quote by Frans B. M. de Waal suggests that genes alone cannot determine or create our human characteristics. It compares genes to seeds dropped onto pavement, implying that they are powerless on their own.

To understand this better, let's consider the analogy of seeds and pavement. When seeds are dropped onto pavement, they lack the necessary conditions and resources to grow into plants. Similarly, genes are like the seeds, and our human characteristics are like the plants.

Genes provide the blueprint or instructions for our characteristics, but they require additional factors to be expressed and developed fully. These additional factors include environmental influences, experiences, and interactions with other people.
For example, let's say a person has genes that predispose them to have a tall stature. However, if they grow up in an environment with limited access to proper nutrition, their potential height may not be fully realized.
In another scenario, someone may have genes that increase their risk of developing a certain disease.

However, if they lead a healthy lifestyle, exercise regularly, and have access to medical care, they can mitigate the impact of those genes and potentially reduce the risk of developing the disease.
Therefore, while genes play a role in shaping our characteristics, they do not act alone. Our environment, experiences, and choices also contribute significantly to who we become.

This understanding highlights the complex interplay between nature (genes) and nurture (environment) in shaping our human characteristics.

The blood moves from the right atria to the right ventricle and then to the lungs, and then from the left atria to the left ventricle and finally to the body. There, blood gets oxygenated at the lungs, and hemoglobin gets oxygen.

Generally, blood enters the right atrium and travels through the atrioventricular valve to the ventricles, then to the lungs via the pulmonary artery, where hemoglobin absorbs oxygen and excretes carbon dioxide. Through the pulmonary veins, oxygenated blood enters the left atrium, travels to the left ventricles, and then reaches the body via the systemic artery.

Hence, blood moves from the right atria to the right ventricle and then to the lungs, where it gets oxygenated as hemoglobin gets oxygen, and then from the left atria to the left ventricle.

The body also excretes waste through the respiratory system (exhaling carbon dioxide) and integumentary system (sweating).

Besides the urinary system, which includes the kidneys and bladder, the human body utilizes two other primary methods to eliminate waste. The respiratory system is responsible for expelling carbon dioxide and water vapor through exhalation.

This process is vital for maintaining the balance of oxygen and carbon dioxide in our bodies. The integumentary system, which consists of the skin, hair, and nails, is another waste elimination mechanism. It helps the body get rid of excess water, salts, and other substances through the process of sweating.

Both of these systems play crucial roles in maintaining the overall health and well-being of our bodies.

If the sea water becomes more acidic, the calcium carbonate in coral reefs will start to dissolve.

Acidity is a measure of how much a solution contains hydrogen ions (H+). Solutions with a high concentration of H+ ions are said to be acidic, while solutions with a low concentration of H+ ions are said to be basic.

This is because the acidity of the water increases the water's ability to dissolve the calcium carbonate, making it harder for the coral to build and maintain their calcium carbonate skeletons. As the calcium carbonate dissolves, the coral reefs will become weaker and more vulnerable to storms and other events that can damage them. In extreme cases, the coral may even die due to the acidic water. This could have devastating impacts on the entire ecosystem that relies on the coral reef.

Explanation:

The adrenal glands are two glands that sit on top of your kidneys that are made up of two distinct parts. The adrenal cortex—the outer part of the gland—produces hormones that are vital to life, such as cortisol (which helps regulate metabolism and helps your body respond to stress) and aldosterone (which helps control blood pressure).

The pituitary gland is sometimes referred to as the thermostat because it controls the other hormone secreting glands in the body. It had the ability to monitor and send appropriate signals to regulate hormones. It controls functions such as thyroid activity, growth, urine production and the function of other organs in the body.

Hope it helps :)

Pituitary and adrenals glands manage the stress during the tests.

The adrenal glands are responsible for producing hormones that help regulate metabolism, blood pressure, stress response, and other essential functions.

For its part, the adrenal medulla, which is located within the adrenal cortex in the center of the gland, is responsible for secreting "stress hormones" such as adrenaline and norepinephrine.

The adrenal glands are an intricate part of the hypothalamic-pituitary-adrenal axis is composed of:

Before the appearance of a danger or stressor, the hypophysi-adrenal axis is activated; there is an instantaneous and automatic reaction that is made up of a series of symptoms that are always the same, although from greater to lesser intensity.

Then the body tries to overcome, adapt or face the presence of stressor that it perceives as a threat, normalizing the levels of corticosteroids.

Therefore, we can conclude that pituitary and adrenals glands manage the stress during the tests.
