Answer:

A. Producing ATP for the cell.

Explanation:

ATP is produced by multiple cellular composition. ATP is synthesized from ADP and phosphate is formed by the process of cellular respiration. Mostly it is produced by enzymes present in the cell. These enzymes convert phosphate into ATP.

Answer:

plant cells have a rigid cell wall that helps it keep shape and animal cells don't

Answer:

Plant cells contain a cell wall to help give better structure and protection than animal cells. Plant cells also contain a large central vacuole that is used to store waste and water. Another thing is that plant cells have an organelle that preforms photosynthesis.

Answer: C. Fertilization would result in a zygote with twice as many chromosomes as the parents.

Explanation: Hope this helps

Answer:

The zygote would have two nuclie

Explanation:

Answer: a nitrogen-containing base, a phosphate, and a pentose sugar

Explanation:

A five-carbon sugar attached to a phosphate group and a nitrogenous base is the best description of the composition of a nucleotide molecule. Thus, the correct option is A.

Nucleotides are the organic molecules which consist of a nucleoside molecule and a phosphate moiety. Nucleotide molecules serve as monomeric units of the nucleic acid polymers such as deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), both of which are the essential biomolecules within all the life-forms which are found on the Earth.

A nucleotide molecule consists of a nitrogen-containing base such as adenine, guanine, thymine, or cytosine in DNA and adenine, guanine, uracil, or cytosine in case of RNA molecule, a phosphate group, and a pentose sugar such as deoxyribose in DNA and ribose in RNA.

Therefore, the correct option is A.

Answer:

Anaerobic respiration is relatively rapid,and it does not require oxygen.

Answer:

B) phagocytosis.

Explanation:

Phagocytosis is a process in which a cell attaches to the element it wishes to enclose on the exterior of the cell and attracts the item within as it encloses it. Phagocytosis is commonly done when the cell, such as a virus or an infected cell, is attempted to destroy things and often is employed by immune cells.

This is quite particular and dependent on the cell being able to bind to an article it wishes to ingest via cell surface receivers.

Phagocytoses differs from other techniques of endocytism. Unless the cell comes in direct contact with the particle it wishes to ingest, Phagocytosis will not occur.

Diffusion is a type of passive transport. It occurs when molecules transfer passively from high concentration to low concentration zones. So, option c is right.

Active transport involves using energy to move molecules across a membrane against a concentration gradient.

Pinocytosis and phagocytosis are both types of endocytosis. Cytosis is the movement of cytoplasm within a cell. Both are examples of active transport since they both require energy.

Diffusion is the passive movement of molecules from a region of high concentration to a region of low concentration across a cell membrane. It's an example of passive transport not active transport.

Therefore, Diffusion is the only option that is not an active transport mechanism. Thus, option C is correct.

D. mitochondria. (that's a weird word lol)

Answer:

A

Explanation:

A. The optimum pH of the enzyme is 6.6.  - this is true. The optimum pH of the enzyme is where its activity is the highest. On the graph, this is pH 6.6 (activity at 100)

B. The optimum pH of the enzyme is 5.8.  - this is false, the activity of the enzyme peaks at 6.6 (100), at 5.8 the activity is 80

C. The enzyme's activity is greater around pH 8.0 than around  pH 5.0  - This is false, the activity at pH 5 is 50, whereas at around 8 it is 20.

D . The enzyme's activity continually increases as pH increases  from 5.0 to 9.0 - this is false. The activity drops between pH 6.6 and pH 9.

1. The reader knows that the boy is about to break up with his girlfriend, but the girlfriend doesn't know. That is dramatic irony

because  Dramatic Irony appears when the readers know something the character does not know. For example, in scary stories, the reader often knows where the bad guy hides, but the character does not. As the character approaches the hiding spot, the readers may experience heightened suspense due to the dramatic irony.

2.Dave's blood pressure medicine game him a heart attack.  That is

Situational irony.

Situational Irony happens when something happens that the reader does not expect to happen. For example, if someone robs a thief in a story, that portrays situational irony. Readers would not expect a thief who robs others to be the one who gets robbed.

3. "Oh, great! I'm so glad it's raining, and I forgot my umbrella."  That is Verbal irony

Verbal Irony occurs when a character says one thing but means something else. This type of irony is also known as sarcasm. For example, a parent might reveal verbal irony, or sarcasm, by showing up at the door of an extremely messy room and commenting, "I've never seen your room this clean before! You are grounded." Clearly, the parent revealed sarcasm when commenting about the cleanliness of the room.

Answer:

in the epicenter

Explanation:

In a Venn Diagram that compares and contrasts the different characteristics or features of the produced plants, "cloning" would be in the epicenter. This is because through the process of "cloning" you are basically copying the core genetic makeup of the plant and creating a brand new plant that shares all of the exact same characteristics and features as the plant's whose genetic makeup was used as a baseline.

Answer:

Carrying Capacity is very important for today as well as for the future.

Explanation:

Carrying Capacity refers to the maximum population of a particular organism that a specific environment can hold. In each and every environment, there are different population of organisms present due to the availability of resources such as food, water and space for living. If these resources are present in large amount then the population of organism will be higher but if these resources are limited, then the population will be lower. Carrying Capacity is also important for the future because with the passage of time, population of human increases which destroy the forests because human requires area for living. So for cutting of forests, the animals migrated to other areas and sometimes die due to no space available for them.

A collection of stars, dust, and gas bound together by gravity is called galaxy.

A galaxy is a collection of stars, dust, and gas bound together by gravity. Galaxies vary in size and shape, and can contain anywhere from a few hundred million to trillions of stars. They also contain other celestial objects such as planets, asteroids, comets, and nebulas. The Milky Way, in which our solar system is a part of, is an example of a galaxy.

A universe is the entirety of everything that exists, including all matter, energy, space, and time, including all galaxies, stars, and all other forms of matter and energy.

A solar system is a group of celestial bodies that orbit around a star, including planets, moons, comets, and asteroids. The sun and all the objects that orbit it, including Earth, are part of the solar system.

A planet is a celestial body that orbits around a star, is spherical in shape and has cleared its orbit of other debris. They do not emit light and heat like stars do, but rather, reflect the light and heat of their host star.

The statement is true about prokaryotic cells - C) Prokaryotic cells don't have a nucleus

Cells come in various shapes and sizes. Based on the presence of a nucleus or membrane-bound organelles, cells are broadly classified as Prokaryotic cells or Eukaryotic cells.

Prokaryotic cells lack both, a well-defined nucleus and membrane-bound cell organelles. Examples of prokaryotes are blue-green algae, bacteria, and mycoplasma.
