Answer

Magnetic force, attraction or REPULSION that ARISES between electrically CHARGED particles because of their motion. It is the basic force RESPONSIBLE for such effects as the action of electric motors and the attraction of MAGNETS for iron.

Answer:

In chemistry, the MOLAR mass of a chemical compound is DEFINED as the mass of a SAMPLE of that compound divided by the amount of substance in that sample, measured in moles. It is OFTEN denoted by M. ... Thus, for example, the molar mass of iron is about 55.845 g/mol.

Experiment:

Objective:

To show experimentally that carbon dioxide is released during respiration.

Apparatus and Materials Required:

A conical flask, a beaker, a cork with a hole, a glass tube bent at right angles at two places, a small test tube, KOH solution, thread, coloured water.

Vaseline and germinating seeds of gram or pea.

Theory:

Respiration is a catabolic process which involves the breakdown of food or complex organic molecules into simpler products, with the release of ENERGY. This process can take place either in the presence of oxygen (aerobic respiration) or in its absence (anaerobic respiration).

The overall reaction mechanism of aerobic respiration involves the oxidation of carbohydrate and the subsequent production of CO2, H2O and energy.

C6H12O6+6O2 → 6CO2 + 6H2O + Energy

Procedure:

1. Take the conical flask and place some germinating gram or pea seeds in it.

2. Insert the shorter end of the glass tube through the hole in the cork and fix it on the conical flask.

3. Before fixing the cork, hang a test tube containing KOH solution inside the conical flask with the help of a thread.

4. Take coloured water in the beaker and keep the longer end of the glass tube dipped inside it.

5. Make the conical flask airtight by applying Vaseline on its rim.

6. Note the INITIAL level of water in the tube.

7. Observe and note the rise in the water level after an HOUR, without disturbing the apparatus.

Observations:

Experiment to Show that CO2 is Released During Respiration

Water level rises up in the bent tube.

Result:The rise in the level of water indicates that CO2 is produced by germinating seeds during respiration. Actually, the germinating seeds respire and produce CO2, which is absorbed by KOH solution. This creates a vacuum in the conical flask. The air present in the bent glass tube moves into the conical flask. This pulls the water in the bent tube further up.

Precautions:

1. Keep the conical flask airtight.

2. Fix the shorter end of the glass tube in such a way that it does not touch the seeds.

3. Use freshly prepared KOH solution.

ANSWER:

Before the 1900s, it was thought that all blood was the same, a misunderstanding that led to FREQUENTLY fatal transfusions of animal blood into humans and hazardous transfusions of blood between people. Human blood is not the same—people belong to different blood groups, depending upon the surface MARKERS found on the red blood cell.

The cells that make up the body's TISSUES and organs are covered with surface markers, or antigens. Red blood cells are no different. This chapter will describe the types of red blood cell antigen and explain why they are so important in medicine today.

Why the amazon is call lungs of the earth?

Ans: In the amazon most RAIN falls always and the most animal not discoverd.....

Tropical rainforests are often CALLED the “lungs of the planet” because they generally draw in carbon dioxide and breathe out oxygen. But the amount of carbon dioxide they absorb, or produce, varies HUGELY with year-to-year variations in the CLIMATE.

Answer:

Explanation:

DOCTOR induce a hormone called oxytocin to induce delivery.

When the foetus grows and is mature enough for parturition. The foetus sends a signal to the MESOMETRIUM layer of the uterus. And the female body produces a hormone called as oxytocin, which creates a contraction in the uterine wall.

This contraction creates more production of oxytocin,that leads to further contraction, This process CONTINUES until the baby is expelled out.

Hence, oxytocin is the hormone required for expulsion of the baby.That is what externally INJECTED by doctors to make the parturition faster.

Answer:

➡️ya biology is a BUNCH of science which tell us about life and living organisms, including their physical STRUCTURE, chemical processes etc.

➡️ Biology examines the structure, function, growth, origin, evolution, and distribution of living things.

➡️It classifies and describes organisms, their functions, how species come into existence, and the interactions they have with each other and with the natural environment.

➡️Four unifying principles form the foundation of modern biology: cell theory, evolution, genetics and homeostasis.

➡️ Biology as a separate science was DEVELOPED in the nineteenth century, as SCIENTISTS discovered that organisms shared fundamental characteristics.

➡️Biology is now a standard subject of instruction at schools and universities around the WORLD, and over a million papers are published annually in a wide array of biology and medicine journals.

Answer:

R H WHITTAKER IN 1969 based on cell STRUCTURE,thallus organisation,NUTRITION,mode of reproduction, phylogenetic relationships.

Each microsporangium has 100 MICROSPORE mother cells which form 400 microspores by meiosis (100 × 4).
In an anther, there are FOUR microsporangia. So, the total NUMBER of microspores will be 4 × 400 = 1600.
As each microspore FORMS one male gametophyte, 1600 male GAMETOPHYTES can be produced.
