Plant cells have a large central vacuole, while animal cells have many smaller vacuoles. Hence option c is correct.
What are vacuole?Vacuole is defined as a region of cytoplasm-free, membrane-lined, and liquid-filled space inside a cell. A membrane-bound cell organelle known as a vacuole. The plant cell's equilibrium depends heavily on the vacuole. It participates in the regulation of cytoplasmic ions, pH, and the control of cell volume and turgor.
Animal cells lack a cell wall, whereas plant cells do. Animal cells lack chloroplasts while those of plants do. Animal cells have many little vacuoles, but plant cells only have one giant vacuole. Animal cells only have a cell membrane, but plant cells have both a cell wall and a cell membrane. Cell walls are used by plants to give the plant structure. Animal cells lack the organelles known as chloroplasts that are present in plant cells.
Thus, plant cells have a large central vacuole, while animal cells have many smaller vacuoles. Hence option c is correct.

D)
E)
Indiana is home to fossilized
The correct answers are:
-Genetic variation decreases in a population of prey after natural selection acts on it.
-Genetic variation exists in a population leading to individuals with adaptations with different survival frequencies.
Genetic variation creates new variants of a gene; such a variant is called an allele. These variations occur as a result of the interaction between individuals with their environment, where it affects them in a way that determines their survival or not, as a consequence of their adaptability to the surrounding context. Thus, natural selection occurs, which establishes which individuals survive and which individuals do not. Thus, individuals characterized as prey who develop defense elements against hunters will be the ones who survive, while those who do not will be the ones who will perish.

describe how the solar system was formed
Explanation:
The Sun and the planets formed together, 4.6 billion years ago, from a cloud of gas and dust called the solar nebula. A shock wave from a nearby supernova explosion probably initiated the collapse of the solar nebula. The Sun formed in the center, and the planets formed in a thin disk orbiting around it. In a similar manner, moons formed orbiting the gas giant planets.
What does a cell need to be a prokaryote cell?
please help me i’m stuck !!
Answer:
The Prokaryotic CellProkaryotes are unicellular organisms that lack organelles or other internal membrane-bound structures. Therefore, they do not have a nucleus, but, instead, generally have a single chromosome: a piece of circular, double-stranded DNA located in an area of the cell called the nucleoid.

Hope this helps, have a great day.
The body systems that would immediately get involved with my reaction to the cut are nervous system, circulatory system, integumentary system. That is option A
The systematic factors that are required for wound healing after sustaining a cut in the finger include:
The nervous system: here the nerve cells in the skin help wounds to heal. When an injury occurs, cells known as glial cells change into repair cells and disseminate into the wound, where they help the skin to regenerate.The circulatory system: The cut surfaces become inflamed and blood clot and cell debris fill the gap between them. Phagocytes from the blood stream, begins to remove the clot and cell debris stimulates fibroblast.The integumentary system: the skin contains extracellular matrix (ECM) which is made of collagen and elastic fibres that provide structure to the skin and are necessary for wound closure.Learn more here:

Why is the scientific method so important in science
The scientific method attempts to minimize the influence of bias or prejudice in the experimenter.
Bias is a disproportionate weight in favor of or against an idea or thing, usually in a way that is closed-minded, prejudicial, or unfair. In science a bias is a systematic error.
which elements would react most easily with each other?
Answer:
an element with a high electronegativity and an element with a single valence electron
Explanation:
Answer:
The Correct answer would be an element with a high electronegativity and with a single valence electron.
Explanation:
Atoms need 8 electrons in their outershells to be stable. If they don't have eight, they will try to borrow from other atoms. So if an atom only needs one more electron, think of it as being desperate and highly reactive. When an atom with only one valence electron (electron in the outershell) comes along, it's the easiest victim to borrow off of.

During Transcription, an)

A. mRNA strand, nucleus
B. polypeptide chain, nucleus
C. protein, cytoplasm
D. tRNA strand, cytoplasm
Answer:
A. mRNA stand, nucleus
Explanation:
Transcription is defined as the process of copying DNA. This happens so that the cell can produce the proteins necessary for basic life functions.
DNA cannot simply be taken out of the nucleus that easily. So, the DNA must be copied into a different form. That's what RNA is for, specifically mRNA.
mRNA stands for "messenger RNA", which is a copy of DNA that can be transported outside the nucleus and be read to produce proteins in ribosomes.
Transcription happens in the nucleus, where the DNA is housed in. It can't be located anywhere else anyways since DNA cannot leave the nucleus.
Therefore, our answer is A.

o the nervous system
O autocrine signaling
A cell sends messages to itself via Autocrine Signaling
Autocrine signaling refers to the generation and extracellular secretion of a given chemical messenger that interacts with receptors present in the plasma membrane of the same target cell, thereby initiating a signal transduction pathway.An example of an autocrine signaling pathway is the production and secretion of the cytokine interleukin-1 (IL-1) pro-inflammatory cytokine in monocytes.Moreover, paracrine signaling is a type of signaling that occurs between local cells.Endocrine signaling is a type of signaling pathway that occurs between distant cells. This type of signaling is mediated by chemical messengers called 'hormones' which are released from endocrine cells and travel throughout the body.Learn more in:
