Non-biodegradable wastewill NOT break down or at least NOT break down for many years. Examples of Non-biodegradableare plastics, metal and glass. Dangerous chemicals and toxins are alsonon-biodegradable, as are plastic grocery bags, plastic water bottles and other similar materials.

The main components of the transport system in human beings are the heart,blood, andblood vessels. Heart pumps oxygenatedbloodthroughout the body. It receives deoxygenatedbloodfrom the various bodypartsand sends this impurebloodto thelungsfor oxygenation

The endosperm is the food storage area of the seed. The purpose of the seed coat is to protect the seed from physical, temperature-related, or water damage. The seed coat also ensures that the plant seed remain in a state of dormancy until conditions are right for the plant embryo to germinate, or sprout. Generally, there is only one seed coat in a seed.

Like my answer if you find it useful!

1)There are various ways through which a plant can reproduce. Reproduction through seeds is one such variant.

Plants can also reproduce by other methods like grafting, or by use of spores.

These are methods of asexual reproduction. Grafting is a method where by branches of plants are cut and ties together to produce an offspring.

2)Vegetative reproduction is also known as vegetative propagation .

ARTIFICIAL METHODS OF VEGETATIVE PROPAGATION :-----------------------------------------------------------

➡️ We have developed certain artificial methods of vegetative propagation like

✴️cutting ✴️layering ✴️grafting and ✴️tissue culture .

Cutting :------------

✳️A Part of the stem is cut and the cut end is planted in most soil after sometime it gives rise to roots and grows into an independent plant .

✳️ Example : mango ,sugarcane and rose .

Layering :--------------

✳️A Portion of one of the lowest prices of the plant is bent towards so that it touches the soil a bring of birth is removed from the portion which is then covered with soil a break or some other any object is used to keep the brands and soil in the place once the brand strike fruits it is cut off from the main plant and grown separately .

✳️ Example : lemon rose and Jasmine .

Grafting :--------------

✳️ This method consists of attaching or tying up a scion with a stock i, A scion is a cutting of a young stem while a stock is the base of a rooted plants stem .the two parts join up after a few days and then grows as a single plant .A scion also called the graft and the stock must be of the same or related spaces .

✳️grafting is very useful if one wants to grow a new variety with certain desirable features such as the colour of a flower or the taste of a fruit .

✳️ Example: mango and rose .

Tissue Culture :----------------------

✳️ many plant tissues such as the growing and of roots, shoots or buds pieces of a leaf or even single cells have the inherent ability to give rise to the old new plant when growth on a suitable growth our culture medium (plural media) .

✳️ This method is also known as micro propagation.

✳️ Example : fruit plants , ornamental plants and plants used in forestry

Vaccination is the most effective method of preventing infectious diseases;widespread immunity due to vaccination is largely responsible for theworldwide eradicationofsmallpoxand the elimination of diseases such aspolioandtetanusfrom much of the world.

OBJECTIVES: Vaccination is aneffectiveway to reduce morbidity and mortality related to infectious diseases

1.Live-attenuated vaccines

Live vaccines use a weakened (or attenuated) form of the germ that causes a disease.Live vaccines are used to protect against:

Measles,mumps,rubella(MMR combined vaccine)

Rotavirus

Smallpox

Chickenpox

Yellow fever

2.Inactivated vaccines

Inactivated vaccines use the killed version of the germ that causes a disease.

Inactivated vaccines usually don’t provide immunity (protection) that’s as strong as live vaccines. So you may need several doses over time (booster shots) in order to get ongoing immunity against diseases.

Inactivated vaccines are used to protect against:

Hepatitis A

Flu(shot only)

Polio(shot only)

Rabies

3.Toxoid vaccines

Toxoid vaccines use a toxin (harmful product) made by the germ that causes a disease. They create immunity to the parts of the germ that cause a disease instead of the germ itself. That means the immune response is targeted to the toxin instead of the whole germ.

Like some other types of vaccines, you may need booster shots to get ongoing protection against diseases.

Toxoid vaccines are used to protect against:

Diphtheria

Tetanus

Going by the hierarchy of the Trophic levels, the plants are primary producers, the herbivores are the primary consumers, and the carnivores are the secondary consumers.

So, according to the 10% law, at every trophic level, the energy is lost in the food due to biological processes like digestion, or energy lost during transfer or during the breakdown of respiration and other functions. Only 10% of the energy is stored in the flesh or in the body parts.

Therefore according to the 10% rule, if the sheep have 50000 J of energy, then when it comes down to next trophic level of the carnivores that includes Man, the energy available will be only 5000 J.

Metastasis is the medical term for cancer that spreads to a different part of the body from where it started. When this happens, doctors say the cancer has “metastasized.” Other names for metastasis are “metastatic cancer” and “stage 4 cancer.” Sometimes the term “advanced cancer” also describes metastatic disease, but this isn’t always true. For instance, “locally advanced” cancer is not the same as metastatic cancer. It describes cancer that has spread to nearby tissues or lymph nodes but not throughout the body.

1. It is universally accepted that DNA is the genetic material, and that in eukaryotes almost all the DNA is present in chromosomes. Thus, the most important function of chromosomes is to provide the genetic information for various cellular functions essential for growth, survival, development, reproduction, etc., of organisms.

2. Another very important function of chromosomes is to protect the genetic material (DNA) from being damaged during cell division. Chromosomes are coated with histones and other proteins which protect it from both chemical (e.g., enzymes) and physical forces.

3. The properties of chromosomes ensure a precise distribution of DNA (genetic material) to the daughter nuclei during cell division. Centromeres of chromosomes perform an important function in chromosome movements during cell division which is due to the contraction of spindle fibres attached to the centromeric regions of chromosomes.

4. Gene action in eukaryotes is believed to be regulated through histone and non-histone proteins associated with chromosomes.

Chromosomes are the thread-like structure found in the nuclei of both animal and plant cells. They are made of protein and one molecule of deoxyribonucleic acid (DNA).

As the genetic material passes from parents to child, the chromosomes are responsible for containing the instructions that make the offspring unique while still carrying traits from the parent. In most organisms, one chromosome is inherited from the mother and the other is inherited from the father; to ensure that offspring carry traits from both parents. It's crucial that certain cells, like reproductive cells, have the correct number of chromosomes in order to function properly.

The structure of chromosomes helps ensure the DNA remains tightly wrapped around the proteins;otherwise, DNA molecules would be too large for the inside of the cells.

Organisms grow by undergoing cell division to produce new cells and replace older, wornout cells. During this cell division, DNA must remain intact and keep its even distributionthroughout the cells. Chromosomes are important to this process to ensure the DNA is accurately replicated.

Ozoneis a gas in the atmosphere that protects everything living on the Earth from harmful ultraviolet (UV) rays from the Sun. Without thelayerofozonein the atmosphere, it would be very difficult for anything to survive on the surface.

Blood is a connective tissue.Its component are RBC (Red Blood Cells), WBC (White Blood Cells) and PLATLETS.Main Functions of Blood are:-1) Transporting oxygen and nutrients to the lungs and tissues.2) Forming blood clots to prevent excess blood loss.3) Carrying cells and antibodies that fight infection.4) Bringing waste products to the kidneys and liver, which filter and clean the blood.

The heart has four chambers: two atria and two ventricles.

1)The right atrium receives oxygen-poor blood from the body and pumps it to the right ventricle.

2)The right ventricle pumps the oxygen-poor blood to the lungs.
