Investigation Why are cells so small?

Answer:

I would say your answer for this question would be Option D: Cellular respiration provides the energy for photosynthesis.

Explanation:

Photosynthesis is  the process by which plants use the energy from sunlight, carbon dioxide, and water and convert them into food, and Cellular resipration is the process by which organisms use oxygen to break down glucose and convert it to usable energy. That means that Option B can be crossed out, along with Option C. In Option A, the products of photosynthesis are not the reactants of cellular respiration, but rather the user of the energy that Cellular respiration provides. That means you can cross out Option A, and now you are left with Option D as your answer.

Answer:

A. The products of photosynthesis are the reactans of cellular respiration

Explanation:

Answer:

As the DNA double helix is unwound by helicase, replication occurs separately on each template strand in antiparallel directions. This process is known as semi-conservative replication because two copies of the original DNA molecule are produced. Each copy contains one original strand and one newly-synthesized strand.

Answer: c. burning of fossil fuels.

Explanation:

Carbon Dioxide and other greenhouse gases like it are the reason some of the sun's heat is trapped in the atmosphere instead of leaving back into space. Any process which increase the amount of carbon dioxide in the atmosphere therefore can increase global warming.

One of the major human activities that involves releasing carbon dioxide is the burning of fossil fuels. We use fossil fuels for many things including producing electricity and driving. When this happens we release a lot of carbon dioxide into the atmosphere thereby making global warming worse.

Answer:

Nondisjunction (during meiosis in gametogenesis)

Explanation:

This is meiosis because we can see germ cells present, and the chromosome number is halved (typically) by the end of the process. This is nondisjunction because the sister chromatids/chromosomes are failing to separate properly during cytokinesis, causing improper amount of chromosomes in the germ cells. So on the left you have nondisjunction during meiosis II, because you have two cells with the proper amount of chromosomes after the first division. And on the right you have nondisjunction during meiosis I, because you have one cell with no chromosomes after the first division. The steps are as follows: 1 - Meiosis, 2 - Meiosis II, 3 - Fertilization, and 4 - Zygote (creation of).

Answer:

coffee is more acidic than water?

Explanation:

i am not sure if this is what you are asking but thats what my first thought to answer was

Answer:

Deoxyribonucleic acid is the macromolecule carries the genetic information. It has two phosphate sugar back bone chains which are joined together with the help of nucleotides (A, T, G, and C). This set of nucleotide refers as gene. These genes define the primary function of DNA to carry genetic information. This DNA structure gets coiled in manner that can carry large amount of information. These nucleotide sequences have ability to get transcribed into protein molecule with the help of translation and transcription factors.

One strand of sequence is sufficient to maintain coding sequence. The pair wise structure helps in case of one strand of structure get damaged and it required in process of replication.

Base stacking provides the stability in the structure of the DNA. The corresponding nucleotides combine with other molecule and minimize the hydrophobic effect. This molecule combines in the perpendicular alignment to the DNA base line.

It often found that TATA box on 5’ end. It is found that on 5’ because process starts from 5’ end and TATA box have A, T nucleotide. These molecules have double hydrogen bond, which is weaker then G, C pair.

Explanation:

Answer: Bottom layer of rock

Explanation:

The bottom layer is the layer of the deposition of the sediments in which sedimentation and cementation occurs to form the rocks. These rocks are formed at the lowest horizon of the soil profile. These rocks are also called bedrocks. The layer present above the rock are younger and the layer at the top is the youngest layer. The older layer at the bottom and the younger layer at the top. This phenomena is called law of superimposition.

Some Prokaryotic organisms are Bacteria, Archaea and E.Coli and Some Eukaryotic organisms are mushrooms, dogs and lizard.

What is the difference between prokaryotic and eukaryotic cells?

Prokaryotic cells are cells without a nucleus. Eukaryotic cells are cells that contain a nucleus. Eukaryotic cells have other organelles besides the nucleus. The only organelles in a prokaryotic cell are ribosomes.

The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not. The nucleus is where eukaryotes store their genetic information.

Eukaryotic cells are cells containing membrane-bound organelles and are the basis for both unicellular and multicellular organisms. In contrast, prokaryotic cells do not have any membrane-bound organelles and are always part of unicellular organisms.

Answer:

Transpiration is when the plant loses water through its leaves. Respiration is when the plant breaks down the sugar in its cells to release energy.

Explanation:

Transpiration and respiration are both processes carried out by plants. Transpiration is the process by which plants lose water via a structure in their leaves called STOMATA. When plants open their stomata for gaseous exchange i.e. take in CO2 or give out O2, they lose water vapor in the process in a process called TRANSPIRATION.

Contrarily, RESPIRATION is a cellular process in which the cells of a plant breakdown sugar molecules (glucose) in order to release energy (ATP) in the process. Respiration equation is as follows:

C6H12O6 + 6O2 → 6CO2 + 6H2O

Transpiration is when the plant loses water through its leaves. Respiration is when the plant breaks down the sugar in its cells to release energy.

A higher density water will be obtained in lower temperature water.

Density is the fluid property that describes the amount of solutes that dissolves in a given volume of the fluid.

Density of a fluid is calculated by taking the ratio of mass to volume of the fluid.

[tex]\rho = \frac{m}{v}[/tex]

where;

When the temperature of the water is low, more mass of the water is obtained while a high temperature evaporates the liquid.

Thus, a higher density water will be obtained in lower temperature water.
