Without enough light, a plant cannot photosynthesise very quickly - even if there is plenty of water and carbon dioxide and a suitable temperature. Increasing the light intensity increases the rate of photosynthesis, until some other factor - a limiting factor - becomes in short supply.

The correct answer to this open question is the following.

There is nothing most important than taking care of your body.

For instance, in the case of the respiratory and circulatory systems. You need to have a good diet that balances proteins, vitamins, carbohydrates, and lots of fruits and vegetables. Vitamin C is very good to strengthen the respiratory system.

Avoid sudden temperature changes, dress in layers, according to the climate conditions.

Regrading the circulatory system, nutrition is as important as any other thing. Avoid fats and excess sugar.

Respect sleeping time because good sleep is of the utmost importance. Be relaxed, avoid stressful situations that could compromise your heart., and practice moderate exercise routines such as walking, jogging, or proper gym routines.

Following are the various ways of preventing diseases  that affect the respiratory and circulatory systems.

Stop smoking, avoid air pollution and exposure to those people who have the viral infections.  Exercise regularly and eat a healthy diet.  Maintain a healthy weight and check up annually to doctor..

Explanation:

When we breathe in, oxygen enters our lungs and enters small sacs in our lungs called the alveoli. In the alveoli, the oxygen diffuses INTO the bloodstream through small blood vessels, called capillaries, that surround these alveoli. The oxygen is now in our bloodstream instead of our lungs and is used in cell respiration etc.

Oppositely, carbon dioxide is diffused FROM the bloodstream TO the alveoli, also through these capillaries. The carbon dioxide is now in the lungs instead of the bloodstream and when you breathe out, the carbon dioxide is breathed out out of your lungs.

Answer:

amritacreate. Atoms are the smallest particle into which an element can be divided. Atoms can join together to form molecules, which in turn form most of the objects around you. Atoms are composed of particles called protons, electrons and neutrons

Explanation:

Answer:

An atom is the smallest unit of matter, and contains three parts: the proton, the neutron, and the electron. A molecule is a group of atoms bonded together.

Explanation:

Answer:proton,electron, helium atom,carbon 14 atom, molecules of glucose

Explanation:

The order for the given scenario can be electron, proton, helium atom, carbon 14 atom, and glucose molecule.

An atom is a matter particle that defines a chemical element uniquely. An atom is made up of a central nucleus and one or more negatively charged electrons.

The nucleus is positively charged and contains one or more protons and neutrons, which are relatively heavy particles.

Protons and neutrons are roughly the same mass. However, one proton is approximately 1,835 times heavier than an electron.

A molecule is two or more atoms linked together by chemical bonds that form the smallest unit of a substance that retains its composition and properties.

Chemistry is built on molecules. Molecules are identified by the element symbol and a subscript indicating the number of atoms.

Thus, the electron, proton, helium atom, carbon 14 atom, and glucose molecule will be the correct arrangement.

Answer:

There are no options to this question, however, it can be answered. The answer is:

All cells arise from previously existing cells

Explanation:

The universal cell theory was proposed in 1830's by three scientists viz: Rudolf Virchow, Mathias Scleiden, and Theodor Schwann. The cell theory consists of three major components which are generally accepted and used till date. The components are:

- All living things are made up of one or more cells

- The cell is the fundamental and basic unit in every living thing.

- All cells arise from previously existing cells via cell division

According to this question, many unscientifically based claims including the believe that fleas actually came from dust have been made. This claim has been DISPROVED by the part of the cell theory that states that "All cells arise from previously existing cells via cell division". Hence, fleas do not arise from dust but from other cells according to cell theory.

It can be deduced that the cell theory that provides a basis for disproving this claim is that all cells are from existing cells.

It should be noted that a cell theory simply means that all biological organisms are made of cells.

In this case, some people believed that fleas actually came from dust. This was proved wrong as the cell theory states that all cells are from existing cells.

Explanation:

Actually, a warmer water is less dense than cold water. It follows that small organisms can easily move through a less dense water. Warm water allows algae to flow through it faster leading to an algal bloom facilitated by climate change.

The water will further be heated up by the fact that the increasing number of algae absorb sunlight thereby further increasing the temperature of the water. The foregoing explains the greater algal bloom in warm years.

Answer:

Rarity itself leads to an increased risk of endangerment and extinction, because rare plants with few and small populations are less able to recover from random events that wipe out individuals or entire populations. This kind of risk is called “stochastic risk”.

Answer:

Chlorophyll

Chloroplast

Explanation:

Chlorophyll is a pigment found in the chloroplast organelle of certain organisms including plants, algae etc. Chlorophyll is the reason plants and certain algae are able to perform photosynthesis because chlorophyll pigment helps them capture light energy from the sun.

According to this question, a xerophytic plant called CACTUS, is being described to possess a chemical in one of its organelle that makes it seem green in appearance. That chemical is CHLOROPHYLL, with chemical formula, C₅₅H₇₂O₅N₄Mg. It is found in the CHLOROPLAST organelle as stated earlier and makes the stem of cactus and other plants green because it reflects green light and absorbs other colour of light. This makes organisms that possess chlorophyll appear GREEN.
