What is a cell?Every living thing is made of smaller and smaller components called cells. There are trillions upon trillions of cells that make up the human body. They take in nutrients from meals, transform those nutrients into energy, and carry out specialized functions while doing so. They are responsible for giving structure for the body.
All cells have four parts:
A plasma membrane, which divides the inside of the cell from its surroundings; Cytoplasm, which is a jelly-like region within the cell that contains various biological components; DNA, which is the genetic material of the cell; and Ribosomes, the protein factory.Learn more about cells, here:

Use the idea of diffuseition to explain how the smell of perfume travel.
Answer:
Diffusion is a process in which a movement of substance takes place from a high concentration area to a low concentration area due to the random movement of the particles.
The smell of perfume travel because the particles move from their high concentration to low concentration and mix with the gases present in the atmosphere. Diffusion happens in gases more faster than liquids and solids because of the random movement of their particles.
List 3 methods of fossilization and describe the process of each
Answer:
preservation of original remains- when the original remain is still in the rock/dirt, typically shells and bones.
permineralization- when the pores of plant materials, bones, and shells are impregnated by mineral matter from the ground, lakes, or oceans
molds and casts- casts preserve a three-dimensional impression of remains buried in sediment, the mineralized impression of the organism left in the sediment is called a mold.
replacement- form when water dissolves away dead tissue and leaves minerals in its place.
compression- a fossil preserved in sedimentary rock that has undergone physical compression
petrifaction- when the organic plant or animal material is replaced with minerals and eventually hardens into rock

Why do you think it’s so important for the mitochondria to work properly ?
They help turn the energy we take from food into energy that the cell can use. But, there is more to mitochondria than energy production. Present in nearly all types of human cell, mitochondria are vital to our survival. They generate the majority of our adenosine triphosphate, the energy currency of the cell.
)) If deer are not hunted legally every season, a potential result is(1 point)
A. the deer population will decrease.
B. the plant population will increase.
C. the predator population will decrease.
D, the smaller herbivore population will decrease.
The awnser is D because if we didnt kill deer there would be a increase in population and a decrease in the food they eat
Explanation
BRAINLIEST PLEASEIf deer are not hunted legally every season, a potential result is that the deer population will increase, not decrease, due to lack of control measures.
What are the various negative impacts for this condition ?This can have negative impacts on the ecosystem, such as overgrazing of vegetation and competition for resources with other herbivores. Additionally, an increase in the deer population can also lead to an increase in the predator population, as more predators may be attracted to the area to prey on the abundant deer.
If deer are not hunted legally every season, the deer population may actually increase. This is because hunting can be an effective way to control deer populations, and without it, there may be no natural predators to control their numbers. As a result, the deer may overgraze vegetation and compete with other herbivores for resources, leading to a decrease in the plant and smaller herbivore populations.
An increase in the deer population can also lead to an increase in the predator population, as more predators may be attracted to the area to prey on the abundant deer. This can have both positive and negative impacts on the ecosystem, as it may increase biodiversity but also lead to competition and potentially negative impacts on other species.
Overall, the management of deer populations is important to maintain a healthy and balanced ecosystem. This can involve regulated hunting, predator control, and other measures to control deer populations and minimize negative impacts on the ecosystem.
Therefore, the correct answer is not listed in the options provided, but of the options listed, the closest answer would be A. the deer population will decrease.

Hich statement best describes a change that usually takes place in the human body when the heart rate increases as a result of exercise?
Complete Question:
Which statement best describes a change that usually takes place in the human body when the heart rate increases as a result of exercise?
Group of answer choices.
A. More oxygen is delivered to muscle cells.
B. Blood cells are excreted at a faster rate.
C. The rate of digestion increases.
D. No hormones are produced.
Answer:
A. More oxygen is delivered to muscle cells.
Explanation:
An aerobic exercise refers to all forms of physical activity that an individual engages in, so as to increase the heart rate (from low to high intensity) in response to the level of oxygen required by any activated or working muscle in the human body.
Generally, aerobic exercise help various individuals to prevent cardiovascular diseases because it makes the heart to beat faster (heart rate increases) to enable it supply more oxygen, which makes the heart to effectively and efficiently pump blood more.
Some examples of aerobic exercise (cardiofitness activity) includes cycling, swimming, jogging, walking, skiing etc.
Hence, the statement which best describes a change that usually takes place in the human body when the heart rate increases as a result of exercise is that more oxygen is delivered to muscle cells.

The fossil record of insects has more gaps and larger gaps than the fossil record of vertebrates. From the following list, choose all the reasons why this is so:
A. Insects were smaller than vertebrates.
B. Insect habitats were not in places where fossils formed.
C. Insects had fewer large, hard body parts that could fossilize the way vertebrates did.
D. Insects left less trace evidence that could fossilize than did vertebrates.
E. There were fewer insects than vertebrates throughout geological history.
Insects left less trace evidence that could fossilize than did vertebrates is the correct reason.
What is Fossil record?A group of fossils that have been examined, classified, and organized both historically and taxonomically make up a fossil record. When organisms die, they are encased in mud and rock and eventually replaced over time by minerals.
These fossils are categorized and organized using a variety of disciplines and specialties, such as comparative anatomy, radiometric dating, and DNA analysis.
Scientists attempt to reconstruct phylogenies, or trees describing the relationships between species, both living and extinct, using information from the fossil record.
Therefore, Insects left less trace evidence that could fossilize than did vertebrates is the correct reason.
