Genetics is the study of how heritable traits are TRANSMITTED from parents to offspring. Humans have long observed that traits TEND to be SIMILAR in FAMILIES. It wasn’t until the mid-nineteenth century that larger implications of genetic inheritance began to be studied scientifically.
Father of Genetics. Gregor Mendel, through his work on pea plants, DISCOVERED the fundamental laws of inheritance. ..

Genetic Engineering: Application # 1. Application in Agriculture:

An important application of recombinant DNA technology is to alter the genotype of crop plants to MAKE them more productive, nutritious, rich in proteins, disease resistant, and less fertilizer consuming. Recombinant DNA technology and tissue culture techniques can produce high yielding cereals, pulses and vegetable crops.

Some plants have been genetically programmed to yield high protein grains that could show resistance to heat, moisture and diseases.

ADVERTISEMENTS:

Some plants may even develop their own fertilizers some have been genetically transformed to make their own insecticides. Through genetic engineering some varieties have been produced that could directly fix ATMOSPHERIC nitrogen and thus there is no DEPENDENCE on fertilizers.

Scientists have developed transgenic potato, tobacco, cotton, corn, strawberry, rape seeds that are resistant to insect pests and certain weedicides.

Bacterium, Bacillus thurenginesis produces a protein which is toxic to insects. Using the techniques of genetic engineering, the gene coding for this toxic protein called Bt gene has been isolated from bacterium and engineered into tomato and tobacco plants. Such transgenic plants showed nee to tobacco horn worms and tomato fruit worms. These genotypes are awaiting RELEASE in USA.

A lymph node or lymph gland is an ovoid or kidney-shaped organ of the lymphatic system, and of the adaptive immune system, that is widely present throughout the body. They are LINKED by the lymphatic vessels as a part of the circulatory system. Lymph NODES are major sites of B and T lymphocytes, and other white blood cells. Lymph nodes are important for the proper functioning of the immune system, acting as filters for foreign particles and CANCER cells. Lymph nodes do not have a detoxification function, which is primarily dealt with by the liver and kidneys.

In the lymphatic system the lymph node is a SECONDARY lymphoid organ.[3] A lymph node is enclosed in a fibrous capsule and is made up of an outer cortex and an inner medulla.[3]

Lymph nodes also have clinical significance. They become inflamed or enlarged in various diseases which may range from trivial throat infections, to life-threatening cancers. The condition of the lymph nodes is very important in cancer staging, which decides the treatment to be used, and determines the prognosis. When swollen, inflamed or enlarged, lymph nodes can be hard, firm or tender.

SEVERAL factors affect the GROWTH of your hair and NAILS. Keratin is a PROTEIN made by cells in your skin that make upyour hair and nails. As keratin cells naturally push upward through the skin, they die and then harden, turning into your hair or nails.

Hi mate.

Thanks for asking this question.

Here is your answer,



The accumulation of the clear fluid in

the tunica vaginalis is known as hydrocele

testes. The most internal membranes CONTAINS

testicle.

In other words the large collection of the

fluid between the visceral and the perietal

layer of the tunica vaginalis is known as

hydrocele.

The most common causes of the hydrocele

is

painless swelling of a scrotum.

Due to the cause of hydrocele the fluid

moves abdominal region to the SCROTAL sac.

Hydrocele generally OCCURS in the only one

side but they SHOW their effects on both sides.

Indirect inguinal hernia indicates the increase

in causes of hydrocele.

This cause generally or commonly found

in the infant boys. In infant girls, it causes the

effects by showing Enlarged labium.

Hence, the cause of the hydrocele is most

common in boys than girls.

Thank you.

He'd be unhappy for a good while, weak and fragile of bone and muscle for a while. It would take weeks for muscle development to CATCH up. It would take up to a few years for his structural BONES to remodel.

But being 10, he's going to prepubescent and still small and light, with his third rapid growth interval still to come.

Ten years later you'd probably have a really tall and wiry kid with no particular disfigurement.

(This assumes the kid was reasonably active during his TIME on mars and he was also receiving correct NUTRITION in all the VARIOUS stages of development.)
