Answer

Hi,

The reactants in cellular respiration are oxygen and glucose

Explanation

The process of cellular respiration takes place in the mitochondria. The reactants are oxygen and glucose and the main product is ATP energy. The waste products of cellular respiration are carbon dioxide and water. In photosynthesis, the reactants are light energy, water, carbon dioxide and chlorophyll to produce oxygen, water and glucose.

Best wishes!

Final answer:

In cellular respiration, oxygen and glucose are reactants that combine to produce ATP, with carbon dioxide and water being byproducts. This process primarily takes place in the mitochondria and is vital to energy production in cells.

Explanation:

Reactants in Cellular Respiration:

In the biological process of cellular respiration, oxygen and glucose are the primary reactants. Oxygen is essential for the breakdown of glucose; a molecule that cells derive from food which provides the necessary chemical energy. This process is critical for producing ATP (adenosine triphosphate), the energy currency of the cell, and occurs primarily within the mitochondria.

The overall chemical reaction for cellular respiration uses one molecule of glucose (C₆H₁₂O₆) and six molecules of oxygen (O₂) to produce energy. This reaction yields six molecules of carbon dioxide (CO₂) and six molecules of water (H₂O) as waste products. It reflects the inverse of photosynthesis, which utilizes carbon dioxide and water to produce glucose and oxygen.

It's noteworthy that every molecule involved in these processes is conserved and recycled in nature, maintaining a balanced and continuous cycle of matter and energy among organisms.

Answer:

D. display an asymmetrical body plan

Explanation:

Most of the animals have bilateral symmetry but sometimes animals show asymmetrical body plan.

Rest of the options are wrong.

Animals are always multicellular and there is no exception to this fact. So, if we will write  sometimes animals are multicellular, it will be a wrong statement.

Animals are eukaryotic organisms so it means that they must have membrane-bound organelles .The organisms which do not have membrane-bound organelles  are known as prokaryotes but animals are eukaryotes. So B statement is wrong.

All the animals are heterotrophs that means that animals cannot produce their own food in any situation so statement C is also wrong.

Cloning produces genetically identical offspring and is both a natural phenomenon and a technique developed by scientists. It occurs in nature, especially among unicellular organisms, and has been achieved in multicellular organisms through reproductive cloning.

Explanation:

Cloning is the process of creating an exact genetic replica of an organism. The clone's DNA is exactly the same as the parent's DNA. The characteristic statements about cloning are:

Cloning can happen through both natural and scientific methods. Unicellular organisms like bacteria reproduce asexually through cellular cloning. Reproductive cloning allows the creation of a clone for entire multicellular organisms and was popularized by the cloning of Dolly the sheep. It is a significant achievement in biotechnology, indicating that identical genetic replication is possible for multicellular organisms through artificial means, despite most such organisms typically reproducing sexually.

The correct answer is - C. Humans.

The stickleback in Loburg Lake, Alaska, is not a native species of the lake. It is thought that this fish was introduced to this lake somewhere between 1984 and 1989. The reason for this kind of suggestion is that the stickleback in this lake had full armor like the stickleback in the seas, which is not something found among the lake populations of this species. Also, the full armor had gradually been reducing with each new generation, and in the present, the stickleback in this lake looks totally the same as the other lake populations.

The stickleback did not had any predators in Loburg Lake, thus the losing of the full armor as it was not needed, instead the stickleback was the predator. But even though it didn't had a predator in the water, the humans became its predator through the recreational fishing that takes place on this lake.

There has been two eons in the Earth's geologic history so far, the Precambrian eon, and the Phanerozoic eon. The eons are the basic and by far longest units on the geological time scale, spreading over hundreds of millions of years.

The Precambrian eon is the eon that starts with the formation of the Earth, up until the development of multi-cellular organisms. A very important event in this eon can be considered the formation of the Earth's oceans, which later enabled the conditions for the development of life. The organisms that dominated this eon are the one cellular organisms.

The Phanerozoic is the eon in which the multi-cellular organisms started to develop and evolve. This eon started with the end of the Precambrian eon, 543 million years ago up until the present. A very important event in this eon is the change of the composition of the atmosphere, which enabled the terrestrial life, as well as the better living conditions for the marine life. It is very hard to choose a dominant form of life in this eon, but worthy of mentioning are the plants, the sinapsids, dinosaurs, mammals, fish.

The two main phases are interphase and mitosis

As far as my knowledge goes, the yellow area is mitosis, and mitosis is a process of cell division which results in two new nuclei (each containing a complete copy of the parental chromosomes)

D. the cell is dividing

Answer:

D. The cell is dividing.

Explanation:

Cell cycle is a series of events that leads to development of two daughter cells from a parent cell. The two main phases of cell cycle are interphase and mitosis. Interphase is the longest phase of cell, while mitosis takes much less time than interphase.

During interphase cell prepares for division and replicates its DNA, while mitotic phase involves actual cell division. During mitosis, division of nucleus and cytoplasm takes place to form two daughter cells.

Thus, the correct answer is option (D).

Final answer:

Gravity and inertia are the two factors that maintain the orbits of the Earth around the sun, and the moon around Earth, providing the equilibrium for their movements in space.

Explanation:

The factors that keep the Earth in orbit around the sun and the moon in orbit around Earth are gravity and inertia. Gravity is the force of attraction between two masses, which in this case are Earth and the sun, and Earth and the moon. Inertia is the tendency of an object to remain in uniform motion unless acted upon by an external force. The balance between gravity pulling the celestial bodies towards each other and inertia trying to keep them moving in a straight line is what keeps them in their respective orbits.

I Believe The Answer Would Be B.

All living organisms are fundamentally similar because they are assembled from a code found in nucleic acids, primarily DNA and RNA. This code forms genes which guide the assembly of proteins, the building blocks of living organisms.

All living organisms on Earth share a fundamental similarity because they are assembled from a code found in nucleic acids. This code is primarily found in the form of DNA (Deoxyribonucleic Acid) and RNA (Ribonucleic Acid) in organisms. The nucleotide bases - Adenine, Thymine, Cytosine, and Guanine in DNA and Adenine, Uracil, Cytosine, and Guanine in RNA - combine in various sequences to form genes which direct the assembly of proteins. Proteins in turn contribute to the make-up of the cells, tissues, and organs of a creature. Though the exact sequence of these bases varies between organisms, their presence in all known life forms shows how organisms are assembled from a code found in nucleic acids.

Its  chlorophyll pigment would be adapted to utilizing the blude-green spectrum of sunlight for photosynthesis rather than the red spectrum like land plants. This is because red light is absorbed by the oceans and does not reach greater depths (this is why oceans appear blue). These plants would therefore appear red in color.

Plants that live in the oceans have air-spaces in their leaves that that help them stand upright in water. They use buoyancy for structural integrity. This is why even long plants such as kelp seem to be upright in water (but will collapse when put on land).

A neutron has no charge

NEUTRAL = NONE

well thats how I remember it anyway

SO ITS NUMBER 2

A neutron has no electrical charge and is electrically neutral. Neutrons are part of the atom's nucleus alongside protons and provide mass to the atom without influencing its net electric charge.

The correct answer is that a neutron has no electrical charge. Neutrons, like protons, reside in the nucleus of an atom. While protons have a positive electrical charge, and electrons have a negative electrical charge, neutrons are electrically neutral. The neutron's lack of charge means that it does not contribute to the electrical characteristics of an atom. Essentially, neutrons provide mass without affecting the charge.

It is noteworthy that although a neutron itself is uncharged, it is composed of smaller particles called quarks, which do have electric charges. However, the sum of the charges of the quarks inside a neutron is zero, which is why the neutron is electrically neutral.
