The part of the cell which contains the instructions that ribosomes use to assemble proteins is (D) nucleus.

Both prokaryotic as well as the eukaryotic cells has a nucleus, which is where the genetic material DNA is contained and which houses information about the entire structure of the organism.

The ribosomes are instructed by the DNA found in the nucleus to assemble the proteins that the cell needs to survive. These ribosomes construct complex proteins by building constituent parts in accordance with directions provided by the DNA. Translation is the term for the process by which proteins are created from DNA.

These are the weights of a potato cube after an experiment of osmosis.

Osmosis is the naturally occurring diffusion or passage of water or other solvents over a semipermeable membrane (one that prevents the passage of solutes, or dissolved compounds). The crucial biological mechanism was initially in-depth investigated in 1877 by German plant physiologist Wilhelm Pfeffer.

Previous researchers had conducted less precise examinations of leaky membranes (such as animal bladders) and the transport of water and escape chemicals through them in opposite directions. Thomas Graham, a British chemist, coined the term "osmose," which is still used to refer to the process, in 1854. A solution will tend to become more diluted by absorbing solvent through a membrane separating it from the pure solvent if the membrane is permeable to the solvent but not to the solute.

During warm summer afternoons, winds called sea breezes blow from cooler ocean to warmer land. It is driven by sunlight and solar heating.

These are the winds that blow from a single direction over a specific area. Generally these winds blow from east to west rather than north and south because of earths rotation.

There are three types of prevailing winds:

The air over land in the coastal areas which heats up more faster during the day and begins to rise. Hence it results in low pressure at the surface. As warm air rises this air enters from sea. As a result wind direction during the day is from sea to land.

Theory of abiogenesis suggests the occurrence of life on earth. It was experimentally demonstrated that complex organic molecules were formed of simple non-living entities.

Theory of abiogenesis was a concept proposed by Huxley in which he suggested that the life forms on the earth have been formed spontaneously from the reaction between the nonlife components on the earth.

The complex living forms were believed to be evolved from the simple forms through various biochemical interactions. This was later demonstrated by Urey and miller in their experiment.

Thus, theory of abiogenesis is important in determining the course of evolution on earth.

Plants need sun but too much sun can dehydrate or damage the plant. As if too water plants need air too breath so adding too much water can drown them

Answer:

Both

Explanation:

Plants harvest energy from the sun with the help of chlorophyll and carotenoid, two photon-capturing molecules. But if the plants are exposed to too much sun, these molecules absorb more energy than they can handle and generate reactive species of oxygen that can destroy the plant.

Intentionally altering the Earth's natural systems on a massive scale to combat climate change is known as geoengineering.

With the use of reflective particles sent purposefully into the upper atmosphere, where they can block the sun's warming rays, solar geoengineering aims to reflect incoming sunlight back into space. First, there is carbon geoengineering, often known as carbon dioxide removal (CDR). The other is solar geoengineering, which is additionally referred to as solar radiation management (SRM), albedo alteration, or sunlight reflection.

Aerobic respiration and fermentation use carbon from glucose as both an electron donor and electron acceptor.

What is aerobic respiration?

The process of aerobic respiration, which takes place in the presence of oxygen and converts glucose into ATP (Adenosine Triphosphate), gives the cell energy.

The procedure includes several phases, such as glycolysis, acetyl coenzyme A synthesis, citric acid cycle, electron transport chain, etc.

Carbon dioxide, water, and ATP energy molecules are the byproducts of aerobic respiration. A chain of electron donors and acceptors is involved in the electron transfer process.  

Therefore, Aerobic respiration and fermentation use carbon from glucose as both an electron donor and electron acceptor.

Light Reaction:

In light reaction it includes the use of light energy for the two molecules which is needed for the next stage of photosynthesis  the energy storage molecule ATP (Adenosine tri phosphate) and the reduced electron carrier NADPH. In plants, the light reactions take place in the thylakoid membranes of organelles called chloroplasts. During the light reaction the chlorophyll absorbs light energy which excites some pigments molecules to higher energy levels.

Dark reaction:

The dark reaction is also called the carbon-fixing reaction. It is a light-independent process in which sugar molecules are formed from carbon dioxide and water molecules. The dark reaction occurs in the stroma of the chloroplast, where they use the products of the light reaction.

So we can conclude that in light reaction it includes the use of light energy for the two molecules. The dark reaction is a light independent reaction.

An isotonic environment outside a cell has same amount of salt, the same as the inside of the cell.

Isotonic solutions are the ones that have the similar concentration of water as well as solutes as cell cytoplasm. Because there is no net gain or loss of water, cells in an isotonic solution will neither shrink nor swell.

When a cell is immersed in an isotonic solution, there is no net flow of water into or out of the cell, and the volume of the cell remains constant.

If the concentration of solutes outside the cell is the same as the concentration inside the cell and the solutes cannot cross the membrane, the solution is isotonic to the cell.

Thus, it has same percentage of salt inside and outside.

What is the momentum of a body?

Linear momentum, translational momentum, or simply momentum is the product of an object's mass and velocity in Newtonian physics. It is a vector quantity with magnitude and direction. If m is an object's mass and v is its velocity (also a vector quantity), then p = mv is the object's momentum.

We can find the momentum of the body using mass and velocity by the relation p = mv.

The deoxyribonucleic acid (DNA) is a double helix composed of two long chains of sequential nucleotides.

   In DNA there are four classes of nucleotides, each containing one different nitrogenous base (i.e., Adenine, Guanine, Cytosine, Thymine).

   According to the base pair rules of complementarity, Adenine always pairs with Thymine, whereas Guanine always pairs with Cytosine.

In conclusion, the order of the bases on the opposite strand of DNA should be Thymine, Guanine, Guanine and Cytosine.

Extinction refers to the complete disappearance of a species or group of organisms from the Earth. Extinction can be caused by a variety of factors such as climate change, habitat destruction, competition, predation, disease, and human activities such as hunting and pollution.

The fossil record is one of the most important sources of evidence for extinction events. When a species goes extinct, its fossils can still be found in the rock record, often in a particular layer of sediment that corresponds to the time period when the extinction occurred.

By studying the fossil record, scientists can identify periods in Earth's history when there was a sudden and widespread disappearance of species, which is known as a mass extinction event.

For example, the fossil record shows that there have been five major mass extinction events in the history of life on Earth, with the most famous being the extinction of the dinosaurs at the end of the Cretaceous period.

The extinction of the dinosaurs is marked by a distinct layer of sediment that contains high levels of iridium, which is rare in Earth's crust but is abundant in asteroids and comets. This layer of sediment suggests that a large asteroid impact may have triggered the extinction of the dinosaurs and many other species.

Overall, the fossil record provides valuable evidence for understanding the history of life on Earth, including the occurrence and causes of extinction events.
