If a plant closes its stomata on a hot, dry, and windy day, the plant response to these conditions is water loss and water stress is highest on hot, dry, windy days. So, the plant closes its stomata to conserve water.

Stomata are the tiny pores present on the surface of the leaves. A huge amount of gaseous exchange may take place in the leaves through these pores for the purpose of photosynthesis.

During photosynthesis, these stomatal pores take carbon dioxide and water is gradually lost, in order to prevent this water loss in hot and humid conditions, the plant closes its stomata.

Therefore, if a plant closes its stomata on a hot, dry, and windy day, the plant response to these conditions is water loss and water stress is highest on hot, dry, windy days. So, the plant closes its stomata to conserve water.

Dependent and independent variables are variables in mathematical modeling, statistical modeling and experimental sciences. Dependent variables receive this name because, in an experiment, their values are studied under the supposition or demand that they depend, by some law or rule, on the values of other variables.

hydrogen is essential to nuclear fusion. hydrogen is the fuel the sun burns. we don't have to burn solar energy, so there's no smoke and pollution

Answer:

Hydrogen fusion reaction is the one which provides so much light and heat (in short, energy) which escapes into space and spread. If Hydrogen on sun ends, It will lose its warmth (and may be soon become a planet, but will surely be a dead star).

P - pepsin / protease

Q - amylase / carbohydrase

R - lipase / trypsin / protease / amylase

(c) There are many ways in which different types of enzymes are using in preparing baby foods such as the amylase breaks down the starch and the starch breaks down to maltose or glucose. The protease breaks down protein and the protein breaks down into amino acids. The lipase breaks down fats and then the fats break down to gylcerol.

Answer:

Though they are often debated, there are eight main characteristics that define a cell as living.

The first is genetic code. All living things contain DNA, which is like the instruction manual for life. DNA is contained in each cell, and passed from parent to offspring.

The second is growth and development. Whether by creating more cells or creating more organelles within the cell, all living things grow and develop.

The third characteristic is reproduction. Reproduction can be sexual or asexual, but in the case of single cells, it is asexual.

The fourth characteristic is response. All living things, including cells, react to external stimuli, such as temperature or salinity.

The fifth characteristic is homeostasis. Homeostasis is the condition by which living things maintain a stable internal environment in the midst of an ever-changing external environment.

The last three characteristics go hand in hand, and are sometimes combined, but in my mind they are distinctly separate.

Sixth is consumption, which is taking in food and other materials. A cell specifically takes in molecules such as water or glucose during consumption.

Seventh is metabolism, which is using materials consumed in order to create energy. Living cells use enzymes to break down materials to produce ATP (adenosine triphosphate), which is usable energy.

Finally, all living cells undergo excretion in some form. Some examples in cells include exocytosis and osmosis.

These 8 characteristics, though often controversial, determine a cell as living.

Answer:

Some rare autotrophs produce food through a process called chemosynthesis, rather than through photosynthesis. ... Instead, they make food using energy from chemical reactions, often combining hydrogen sulfide or methane with oxygen.

Answer:

A) Cellular Respiration

Explanation:

Heterotrophs undergo cellular respiration in order to turn the food they eat into energy they can use and unlike autotrophs, they cannot make their own energy so photosynthesis isn't required.

Answer:

if a special effects artist mixes two different liquids in a bowl and they both are too white !

after heats those liquids

its forms curd like substance

its either will be white, its can increase its colour as darkish white or lightly yellowishblack

when she heats the bowl, a new compound forms and it will be white before heating and after heating it may be white or other dark color.

A compound composed up of two or more elements which are chemically combined with a fixed proportion by their mass.

For example, Water, Sodium Chloride,  Ammonium Chloride etc.

They have fixed melting and  boiling points.

Formation of compound is a change in chemical reaction and the components of compound are mixed in a fixed proportion.

Two major types of compounds are covalent and ionic compounds.

Covalent compounds refers to formation of covalent bond among two nonmetals, like water or methane. These molecules are neutral and weak.

When metal react with non metal it form Ionic compounds, are held together by opposite charges, so the bond is stronger than covalent compound.

Answer:

C. I and III

Explanation:

A mutation needs to occur in a gamete cell in order to be passed down to the next generation.

If it occurs in a somatic (body) cell, the mutation will only be present in that organism.

On the other hand, in a gamete cell, the mutation will pass down because gamete cells are directly involved in the genetic makeup of the offspring.

So, since sperm and egg cells are gametes, mutations in those cells would get passed on.

The correct answer is C. I and III

Answer:

The nuclear receptor superfamily comprises a large group of transcription factors that play a key regulatory role in development and homeostasis of multicellular organisms. A special feature of nuclear receptors is their ability to bind to condensed chromatin templates, which makes them important initiators of gene transcription. Moreover, the ability of nuclear receptors to sequentially recruit a variety of transcription factors and coregulators to target promoters and to orchestrate the whole process of gene transcription confirms their biological significance and stimulates intensive research and a high level of scientific interest in this field. In this review, we summarise current knowledge regarding the structure and function of nuclear receptors as principal regulators of gene expression. Emphasis is given to the molecular mechanisms of nuclear receptor-mediated transcriptional activation and repression including recent progress made in this area.
