• Gene therapy has some potential risks. A gene can't easily be INSERTED DIRECTLY into your cells. Rather, it usually has to be delivered using a carrier, CALLED a vector. The most common gene therapy vectors are viruses because they can recognize certain cells and carry GENETIC material into the cells' genes.

Answer:

Transpiration pull is the force which helps movement of water from roots of the plants to leaves.

Explanation:

A transpiration pull COULD be simply defined as a biological process in which the force of pulling is produced inside the xylem tissue. This force helps in the upward movement of water into the xylem vessels. In this process, loss of water in the FORM of vapours through leaves are observed. This biological process is carried out in all HIGHER plants and trees as their stems are surrounded by bundles of fine tubes, which are made from a woody material known as xylem.

Transpiration pull is also referred as suction force and this force is used to DRAW the water in an upward direction from the roots to the leaves. The amount of water received by the leaves are used for the PHOTOSYNTHESIS and the excess amount of water is released into the atmosphere in the form of vapours through the openings in the leaves known as stomata.

• Thymus:- It helps in the production of T-cells, functioning of the adaptive immune system and maturity of the thymus.
• Thyroid:- It produces hormones that AFFECT the heart rate and how CALORIES are burnt.
• Adrenal:-This gland produces the hormones that control the sex drive, cortisol and stress HORMONE.
• Pituitary:- It is also termed as the “master control gland”. This is because the pituitary gland helps in controlling other glands.
• Pancreas:-This gland is involved in the production of insulin hormones, which plays a crucial role in maintaining blood sugar levels.
• Testes:- In men,the testes secrete the male sex hormone,testosterone. It also produces sperm.
• Ovaries:- In the female REPRODUCTIVE system, the ovaries release ESTROGEN, progesterone, testosterone and other female sex hormones.

Human activities affect the environment in recent times in the form of global warming, floods, cyclones, tsunamis etc which are a few consequences of various activities of man.

Explanation:

Few are:

Deforestation: Trees take in carbon dioxide and give out oxygen to nature, which is used by us for survival. Cutting down of trees for land availability due to a rise in population and to bring up new industries has got an imbalance in the ecological system, resulting in a decrease in the oxygen levels in the air.

Water Pollution: Contaminated water from large scale industries, lack of proper sewage systems, various human activities near water BODIES have caused water pollution to large extents. Also, sometimes seas and oceans face oil spillages, which has long term effects on water, leaving it unavailable for consumption.

Air pollution: Overpopulation has immensely caused air pollution in many ways, one of which is the use of vehicles for transportation. Harmful gases from industries are left into the air, causing us to breathe air that has poisonous chemicals leading to new medical ailments.

Exploitation of Marine life: Due to extensive fishing activities, our marine life is becoming extinct. Water pollution causes a disturbance in AQUATIC life and makes survival questionable. When these fish are consumed by humans, it leads to illness and death too in certain cases.

Global warming: Is seen as a RESULT of an increase in the temperature of the earth as a result of the greenhouse effect and related human activities. It results in the melting of ice caps and hence rises in sea levels causing tsunamis, cyclones, and other natural disasters.

Habitat destruction: Survival of wildlife is becoming difficult as their natural habitat is being cut down. Deforestation may result in the availability of land but leaves animals homeless.

Extinction: Animals are becoming endangered because of – non-availability of natural habitat, threats from the environment, predators, hunting, pollution, destruction.

Harmful chemicals and fertilizers: With a rise in population, there is an increase in the DEMAND for food. To meet this availability, plants are being grown with the use of harmful fertilizers which have very LOW nutritious values.

Urbanization: Has brought about a significant change and imbalance in our ecological system.

All the living organism present in an ECOSYSTEM are called the biotic COMPONENTS of that ecosystem.

Explanation:

any biotic components of any ecosystem can be CLASSIFIED into 3 stages:

2. consumers/heterotrophs : these are the organisms that consume the producer in form of food to survive

3. decomposes : thses are the organisms that feed on the dead and decaying organism and contribute the non CONVERTIBLE forms of dead body into soil.
