The organisms that are able to perform photosynthesis that include plants, algae and cyanobacteria release oxygen in the atmosphere.

Photosynthesis is a process that uses light energy from the sun to convert carbon dioxide and water to oxygen and glucose. The reaction is  given as:

6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂

That is, CO₂ is taken up from the atmosphere and O₂ that is formed is released back into the atmosphere.

Photosynthesis is a multistep process and occurs in two phases - light-dependent reactions and Calvin cycle.

The main purpose is obtaining energy in the form of sugar. Glucose that is formed is further catabolized to give ATP, which is the main source of energy.

It occurs in the chloroplasts. The light-dependent reactions occurs in the thylakoid membrane and the Calvin cycle occurs in the stroma.

It is because of photosynthesis that plants, algae and cyanobacteria are said to be autotrophic, that is capable of producing its own food.

Explanation:

A geologic map is a map that is made to show geological features, such as the types of rock or sediment present in a particular region. In these maps, rock units are usually shown by color or symbols in order to indicate where they are exposed at the surface. Geologic maps can sometimes be superimposed over a topographic map.

Answer:

Point C

Explanation:

Oxygen is a by-product of photosynthesis, so when the oxygen production is at its highest, photosynthesis is also at its highest.

Answer:

A. Point C

Explanation:

The plant which is evolving most oxygen is performing the most photosynthesis because during photosynthesis inorganic carbon dioxide and water react in the presence of sunlight to synthesis organic molecule known as glucose and oxygen is evolved.  

The reaction for photosynthesis is depicted as under:

      6CO₂       +   6H₂O    +  sunlight      →    C₆H₁₂O₆    +     6O₂

   (carbon          (water)                                 (glucose )       (oxygen)

   dioxide)  

So, more evolution of O₂ (oxygen) implies more photosynthesis.

Answer:

According to the theory of isostasy, the statement that correct is C.

Explanation:

Ok, let's first explain what the isostasy is: the Isostasy is the ideal theoretical balance of all large portions of Earth’s lithosphere as though they were floating on the denser underlying layer, the asthenosphere, a section of the upper mantle composed of weak, plastic rock.

The asthenosphere is a part of the upper mantle just below the lithosphere that is involved in plate tectonic movement and isostatic adjustments. And the lithosphere is the solid, outer part of the Earth. The lithosphere includes the brittle upper portion of the mantle and the crust, the outermost layers of Earth’s structure.

Taking into account these characteristics, the lithosphere is less dense than the asthenosphere. This is because less dense substances (lithosphere) will float on top of denser substances (asthenosphere). Since the lithosphere is on top of the asthenosphere it must be less dense.

Answer:

C. The asthenosphere is denser than the lithosphere.

Explanation:

The theory of isostasy states that the deeper layers of earth crust must have higher density than that of upper layers. It is required to allow the upper lighter layers to float on the underlying denser layers. Since asthenosphere is present below lithosphere, the asthenosphere is denser than the lithosphere.

Answer:

A scientific theory is a well-substantiated explanation of some aspect of the natural world, based on a body of facts that have been repeatedly confirmed through observation and experiment.

Explanation: Hope this helps!!

A well-supported explanation of a feature of the natural world is called a scientific theory. It is based on a collection of facts that have been repeatedly verified via observation and experiment.

Such ideas are not "guesses," but rather trustworthy descriptions of reality. More than "simply a theory," biological evolution is a reality. It is just as factually accurate as the atomic theory of matter or the germ theory of disease in explaining the cosmos.

We're still working to fully comprehend gravity. Yet, just like evolution, the gravity phenomenon is a well-established fact.

Here are some of the key features of a scientific theory:

It is based on a body of evidence.

It is testable.

It is predictive.

It is widely accepted by the scientific community.

A hypothesis is not the same thing as a scientific theory. A hypothesis is a theory put up to explain a phenomenon. A well-researched and well-backed hypothesis is a theory.

Here are some examples of scientific theories:

The theory of gravity.

The theory of evolution.

The theory of relativity.

The scientific community generally accepts all of these hypotheses because they are testable, falsifiable, and predictive, and they are founded on a body of data.

Although scientific theories are not facts, they offer the most comprehensive account of the natural world that we know. While they are continuously tested and improved, they have withstood the test of time.

Answer:The answer is C. Centrifugal force

Explanation:

Answer:

The Centrifugal force makes the seawater to bulge at the equator when compared to the seawater at the poles.

Explanation:

The centrifugal force drives the earth rotation due to the bulging known as the equatorial bulging. But it is a different effect from tidal bulging.

Relatively the tidal effects are caused by the gravitational gradients that mean the differences in the gravity from one point to another point in the earth.

So centrifugal force is the reason for the bulge of seawater at the equator.

Answer:

Fusion energy which is the exact opposite of fission energy is a more reliable energy that is very sought after by scientist.

Explanation:

Fusion energy does not produce runaway chain reactions so there is no need to worry about meltdowns it also does not produce as much radioactive waist. it's very hard energy to get two, the temperature would need to be about 100 million degrees Celsius six times hotter then the core of the sun.

Fusion has the potential to provide the kind of baseload energy needed to provide electricity to our cities and our industries.

The fusion process has been studied in order to understand nuclear matter and forces, to learn more about the nuclear physics of stellar objects, and to develop thermonuclear weapons.

Fusion power is a proposed form of power generation that would generate electricity by using heat from nuclear fusion reactions.

Answer: Chemical energy

Explanation: During light dependent reactions of photosynthesis, light is absorbed by chlorophyll and other light absorbing pigments. The light energy absorbed is conserved as ATP and NADPH. In light dependent reactions, the light energy is used to split water molecules into hydrogen ions and oxygen molecules and consequent production of ATP and NADPH. This reaction is called photolysis of water. The oxygen molecules is evolved while the hydrogen ions are transferred to NADP+ to produce NADPH. In light dependent reactions, ATP and NADPH are produced.

ATP and NADPH are forms of chemical energy which are usable in the cells. Therefore, light energy is converted into chemical energy in light dependent reactions of photosynthesis.

meosis cell division occurs in reproductive cells and sperm cell is one of the reproductive cells.

Answer:

The correct answer is option-sperm cell.

Explanation:

Meiosis is a type of cell division which produces cells with different genetic material. It produces different genetic material.

Since meiosis is involved in the production of four daughter cells with reduced genetic material that is 'n' from 2n parental cells, it is involved in the production of gamete cells that is sperm cells.

Thus, the option-sperm cell is the correct answer.

E) both (a) and (c). Is the answer

Increased genetic diversity is achieved through both sexual reproduction and conjugation.  The correct answer is E) both (a) and (c).

Sexual reproduction involves the combination of genetic material from two individuals, leading to offspring that are genetically distinct from their parents and each other. This process introduces genetic variations through mechanisms such as crossing over during meiosis and the random assortment of chromosomes. These variations contribute to the genetic diversity within a population, which can be advantageous in adapting to changing environments.

Conjugation is a process found in some bacteria where there is a direct transfer of DNA between two cells that are temporarily joined. While not sexual reproduction in the traditional sense, it similarly results in increased genetic variation in the population.

Answer:

For your first paragraph: While James Watson and Francis Crick are credited with discovering the structure of DNA, they would not have been able to do it on their own.  Without photo 51, taken by Rosalind Franklin using X-ray chromatography, they would not have known that the shape was a double helix.  Chargaff discovered that in DNA the number of guanine units is equal to the number of cytosine units, and the number of adenine units is equal to the number of thymine units. This hinted at the base pair makeup of DNA.

Explanation:

For your first paragraph talk about the first prompt (What were the key contributions of the scientists involved in the discovery of the structure?). Watson and Crick were given the Nobel prize for there discovery of DNA's structure but Rosalind Franklin got a picture that proved the double helix, and Chargaff discovered that adenine went to thymine, and guanine went to cytosine.
