Answer:

Explanation:

A positive feedback loop takes places when when ONCOGENES are there because of mutation in the proto-oncogenes.

In this condition, the cells start multiplying uncontrollably.

Nothing can practically stop their growth.

Tumor suppressor genes in cancer make a negative feedback DUE to apoptosis in cells that can lead to a CANCEROUS condition.

Therefore, Oncogenes HAPPEN due to the turning on of proto-oncogenes whereas tumor suppressor genes may CAUSE cancer while they are turned off.

Thyroxine hormone is secreted by thyroid gland. It HELPS in muscle FUNCTION, heart function and digestion. Less production causes hypothyroidism. It is said that we should take IODINE, for the proper secretion of thyroxine and for its functioning. The hypersecretion causes thyrotoxicosis. It means we have less level of Thyroxine Stimulating Hormone in our bloodstream.

Answer:

a) i. It is the largest part of the brain and is composed of right and left hemispheres.

ii. It performs higher functions like interpreting touch, vision and hearing, as well as SPEECH, REASONING, emotions, learning, and fine control of movement.

b) i. The medulla oblongata is located in the brain stem, ANTERIOR to (in front of) the cerebellum.

ii. The medulla oblongata is located in the brain stem, anterior to (in front of) the cerebellum. This is a cone-shaped, neuronal (nerve cell) mass in the hindbrain, which controls a number of autonomic (involuntary) functions.

This section of the brain helps transfer messages to the spinal cord and the thalamus, which is in the brain, from the body. The main function of the thalamus is to process information to and from the spinal cord and the cerebellum.

The medulla oblongata helps regulate breathing, HEART and blood vessel function, digestion, sneezing, and swallowing. This part of the brain is a center for respiration and circulation. Sensory and motor neurons (nerve cells) from the forebrain and midbrain travel through the medulla.

c) i. The hypothalamus is a portion of the brain that contains a number of small nuclei with a variety of functions.

ii. One of the most important functions of the hypothalamus is to link the nervous system to the endocrine system via the pituitary GLAND.

Answer:

The spinal cord is the main pathway for information connecting the brain and peripheral nervous system. The human spinal cord is protected by the bony spinal column shown to the LEFT. The spinal column is made up of bones called vertebrae.

Explanation:

The spinal cord is a long, thin, TUBULAR structure made up of nervous tissue, which extends from the medulla oblongata in the brainstem to the lumbar region of the vertebral column. It encloses the central canal of the spinal cord, which contains cerebrospinal fluid. The brain and spinal cord together make up the central nervous system (CNS). In humans, the spinal cord begins at the occipital bone, PASSING through the foramen magnum and ENTERING the spinal canal at the BEGINNING of the cervical vertebrae. The spinal cord extends down to between the first and second lumbar vertebrae, where it ends. The enclosing bony vertebral column protects the relatively shorter spinal cord. It is around 45 cm (18 in) in men and around 43 cm (17 in) long in women. The diameter of the spinal cord ranges from 13 mm (1⁄2 in) in the cervical and lumbar regions to 6.4 mm (1⁄4 in) in the thoracic area.

Answer:

form, carbon, oxygen, CELLS ...

As blood circulates around the body, it picks up oxygen from the LUNGS, NUTRIENTS from the small INTESTINE, and hormones from the endocrine glands, and delivers these to the cells. Blood then picks up carbon dioxide and CELLULAR wastes from cells and delivers these to the lungs and kidneys, where they are excreted.

Answer:

Living organisms are well organised structure, they can have tissue, tissues have cell cells have smaller components in them, and so on. Because of the effects of environment, this organised, ordered nature of living structures is very likely to keep breaking down over time. If ORDER breaks down, the organism no longer be alive. So living creatures MUST keep repairing and maintaining their structures. SINCE all these structures all made of molecules they must move molecules around all time.

Answer:

(1) All plants are TALL in F1 progeny

Because tall plant is dominant (TT) and short plant is ressesive (tt) and by crossing it we could GET (Tt), (Tt), (Tt), (Tt).

By crossing F1 progeny we could get phenotype RATIO as 3:1 in F2 progeny

(2) F2 projeny is DIFFERENT from F1 progeny because in F1 progeny we get all same character plant that is tall but in F2 progeny we get all the characters of HEIGHT that is tall and short

Explanation:

Although sexually transmitted diseases (STDs) are underreported and underrecognized, they are a major source of morbidity, mortality, and represent a major socioeconomic cost in developing and industrialized nations. INDIVIDUALS who DEVELOP STDs are often coinfected with human immunodeficiency VIRUS (HIV). Coinfection with HIV both facilitates the natural history of STDs and worsens the CLINICAL picture. The objective of this article is to provide a review to the practicing clinician on the epidemiology, clinical manifestations, methods of diagnosis, and treatment for four cutaneous STDs--chancroid, genital herpes, GRANULOMA inguinale, and lymphogranuloma venereum--in coinfected HIV patients.
