Answer:
14. f. diffusion
15. a. excreting waste
16. b. exocytosis
17. a, endocytosis
Explanation:
14. The movement of molecules from a high concentration to a low concentration is diffusion. Active transport uses energy to move molecules against their concentration gradient (from low to high). Osmosis specifically refers to water molecules. Endocytosis is the movement of molecules inside the cells via the cell membrane engulfing it.
15. The membrane controls the substances that enter and exit the cell, therefore it is involved in excreting waste products from inside the cell.
16/17 Endocytosis is engulfing substances to bring them inside the cell. Exocytosis is the reverse process, where substances exit the cell by fusing with the cell membrane. The movement of molecules from a high concentration to a low concentration is diffusion. Osmosis specifically refers to water molecules.

Answers
Answer:
Plasma
Explanation:
We don't have the figure, but I think the answer is probably plasma.
Blood plasma is the fluid that blood cells are suspended in. When blood is spun at high speed, the cells separate away from the plasma into different layers because of their different weights and shapes.
Plasma is liquid portion of blood. It transports nutrients and wastes and maintains homeostasis.

What are two ways that variation can be described?
Answers
Answer:
varyatio of somthing and multiple varitons of it
Explanation:
The two ways that variation can be described are meiosis and evolution, because in the meiosis process, sexual reproduction occurs, and in the evolution process, changes in animals are seen and variation is observed.
What is variation?When sexual reproduction occurs, there is variation seen because in meiosis genes cross over and recombinate, resulting in variation in offspring from their parents, but it is absent in asexual reproduction that is caused by mitosis or binary fission because here there is no variation in the offspring and the parents. The process of evolution introduces variation because, along with environmental factors, the animal genes are influenced too.
Hence, the two ways that variation can be described are meiosis and evolution, because in the meiosis process, sexual reproduction occurs, and in the evolution process, changes in animals are seen and variation is observed.

How might this change affect the structure and function of the protein?
Answers
Answer:
Explanation:
Three-dimensional folding of a protein is due to interactions among the R groups of the amino acids. Cysteine has a sulfhydryl group, which may form a disulfide bridge with another part of the polypeptide chain. Valine has no sulfhydryl group and is nonpolar, which will affect how the polypeptide will fold.
Match each tool with its influence on science
Answers
Answer:
xray - allows scientists to see dense structures
Microscope - view things that cannot be seen with the naked eye
Telescope - stars, planets and black holes
Ultrasound - see inside the body in real time
Explanation:
Xrays shows highlights dense structures within the body (bones). But is not in real time, usually there images that are captured and reviews later.
Microscope - the clue is in the name, think micro= tiny! Therefore cant be seen by the naked eye. The "scope" part of the word means to look at or observe. So put them together and you get to look at or observe tiny things.
Telescope - the first part of this word "tele", means something far away or at distance. Which gives a clue at what it does, add on the "scope" meaning of to look at or observe and you get; to look at or observe something that is far away.
Ultrasound - this is what is used to monitor the health of babies when they're still developing. It can be seen in real time.
X-rays enable researchers to observe dense formations. View objects using a microscope that is invisible to the eye. Telescope: black holes, planets, and stars see into the body in real-time using ultrasound.
What is the tool microscope's influence on science?X-rays depict the body's dense internal architecture (bones). But it's not in real-time, typically, pictures are taken and then looked at afterward.
The name of the instrument, "microscope," gives it away—think small! as a result, not visible to the eye. The word "telescope" refers to anything far out or remote in its first half.
When a baby is still developing, their health is monitored using ultrasound technology.
Therefore, view objects using a microscope that is invisible to the eye.

What are the differences encountered in the photosynthetic-respiratory pathway of the carbon cycle, as it exists on land and in the ocean?
In a marine environment, the role of plants is performed by _______(phytoplankton, zooplankton, microorganisms) and an additional flux of carbon into the oceans is through _______(aeration, diffusion, deposition).
Answers
Answer:
phytoplankton; diffusion
Explanation:
"Phytoplankton" takes the role of the plant in the marine environment because it consists of tiny plants that contain chlorophyll–just like the terrestrial plants. This provides food to many aquatic animals in the ocean.
When it comes to carbon cycle, carbon dioxide from the atmosphere is being diffused into the ocean by dissolving it. The carbon in the ocean turns into an organic matter through the process of photosynthesis. The ocean is said to have more carbon compared to the atmosphere because many marine animals use it for survival.

termites are insects that feed on wood, which contains cellucose. scientist have observed that some termite species prefer wood that has been attacked by fungi. Construct an explanation for this observation
Answers
Answer:
In this observation, the termites and the fungi rely on each other in order for survival. In other words, they have a symbiotic relationship. This type of fungi helps the termites by digesting cellulose from the wood since termites are unable to digest it. In turn, the termites provide the fungi an environment where they can be cultivated. This explains why termites prefer a wood that was inhabited by fungi.

which would a scientist most likely examine to locate gene mutations?
Answers
Answer:
Single base pair mutations can be identified by any of the following methods: Direct sequencing, which involves identifying each individual base pair, in sequence, and comparing the sequence to that of the normal gene.
DNA is the molecule which is most likely to be examined to locate gene mutations. Thus, the correct option is A.
What are Gene mutations?Genetic mutations are the changes to the DNA sequence which happen during the process of cellular division when the cells make copies of the DNA molecules. The DNA molecule tells body how to form and function well.
Genetic mutations are the changes which could lead to genetic conditions such as cancer, or they could help the humans to better adapt to their environmental conditions over a period of time.
Mutations can be of many different types, such as substitution, deletion, insertion, and translocation of the genetic sequence.
Therefore, the correct option is A.

and chemical changes as they cook.
One of the ingredients for her main course undergoes physical changes. Which of the
following is a physical change?
boiling water
cooking eggs
O grilling hamburgers
O baking bread
Answers
Answer:
Boiling water
Explanation:
Boiling water is an example of physical change as it does not cause any change in the chemical composition of water.
What are physical changes?Physical changes are defined as changes which affect only the form of a substance but not it's chemical composition. They are used to separate mixtures in to chemical components but cannot be used to separate compounds to simpler compounds.
Physical changes are always reversible using physical means and involve a change in the physical properties.Examples of physical changes include melting,boiling , change in texture, size,color,volume and density.Magnetism, crystallization, formation of alloys are all reversible and hence physical changes.
They involve only rearrangement of atoms and are often characterized to be changes which are reversible.
