Answer:
If a cell is in a medium with the same concentration of solutes with respect to intracellular space —isotonic— there will be no movement of water because there is no osmotic gradient or osmosis.
Explanation:
Osmosis implies the passage of water through a semi-permeable membrane from a place with a lower concentration of solutes to one where the concentration of solutes is higher. This difference in solutes concentration on both sides of the membrane produces an osmotic gradient, where the water will move towards the space with the highest concentration of solutes.
If a cell is in an isotonic medium —the same concentration of solutes inside and outside the cell— there is an equilibrium and the osmotic gradient is non-existent, so there is no movement of water or osmosis.

A restaurant owner wants to serve fresh-cut fruit. What factors
might be considered in choosing a recipe and preparation method?
Answer:
A factors might be considered in choosing a recipe and preparation method is discussed below in details.
Explanation:
Explanation:
1.Oxidation- some fruit after slicing on vulnerable to air starts to oxidize this drives to a shift of color, this color shift could differ from light brownish to blackish brown in some fruits such as apple this could perform it appealing to the customer.
2. Shelf life- How prolonged can the fruits begin after disclosure to air before it starts to lose its gustation believing they are not eaten quickly. This has to acknowledge in choosing fruits.
3. Time- How long will it take to make and prepare the fruits ready, some fruits demands some thorough cleansing, expert cutting skill
if all will be possible and will match up the time needed for the fruits to be served.

which type of succession occurs more rapidly what kind of disturbances could lead to this process
Answer:
Secondary Succession
Explanation:
Secondary Succession is faster than primary succession because soil is already there, and the soil usually contains many nutrients.
Examples: Secondary succession occurs when the severity of disturbance is insufficient to remove all the existing vegetation and soil from a site. Many different kinds of disturbances, such as fire, flooding, windstorms, and human activities (e.g., logging of forests) can initiate secondary succession.

The arm's principal muscle groups are in charge of the upper limb's different movements. These muscles consist of:
What is the location of two-headed biceps brachii muscle ?The two-headed biceps brachii muscle is situated near the front of the upper arm. It is in charge of flexing the elbow joint and supinating (moving the palm upward) the forearm.
Triceps brachii: The three-headed triceps brachii muscle is situated near the rear of the upper arm. The elbow joint's extension is controlled by it.
The brachialis is a muscle in the front of the upper arm, next to the biceps brachii. The elbow joint can flex thanks to it.
Pronator teres: The pronator teres is a forearm muscle that aids in pronating the forearm, or turning the palm downward.
Supinator: The supinator is a forearm muscle that aids in supinating the forearm (turning the palm upward).
Anconeus: The anconeus is a tiny muscle that helps the triceps brachii expand the elbow joint. It is situated at the back of the elbow joint.
Together, these muscles enable a variety of arm movements, including as elbow flexion and extension, forearm pronation and supination, and shoulder joint movement.

What does oxygen do in cellular respiration?
Answer:
Your body cells use the oxygen you breathe to get energy from the food you eat. This process is called cellular respiration. During cellular respiration the cell uses oxygen to break down sugar. Breaking down sugar produces the energy your body needs.

Plsss help
Answer: A
Explanation:
A. Suzie Q wants to know the effect of different colors of light on the growth of plants. She believes that plants can survive best in white light. She buys 5 ferns of the same species, which are all approximately the same age and height. She places one in white light, one in blue light, one in green light, one in red light and one in the closet. All of the ferns are planted in Miracle-Grow and given 20 mL of water once a day for 2 weeks. After the two weeks, Suzie observes the plants and makes measurements.
Answer:
This question is incomplete, the complete part is: What is the independent variable in this experiment? A) The plant species B) The amount of water that each plant gets C) The amount of time D) The different types of light the plants were put under.
The answer is D
Explanation:
In an experiment, the INDEPENDENT VARIABLE is the variable that is changed or manipulated by the experimenter in order to effect a measurable response.
In this case, Suzie Q wants to know the effect of different colors of light on the growth of plants. She conducts this experiment using different colors of light namely: white light, green light, blue light, red light etc. This shows that the variable being changed/manipulated is the different colors of light. Hence, the INDEPENDENT VARIABLE is the DIFFERENT TYPES OF LIGHT THE PLANT WERE PUT UNDER.
restriction enzymes cut DNA at totally random places. true of false?
Answer:
False
Explanation:
Restriction enzymes, also called restriction endonucleases, are enzymes found in bacteria that cut DNA. They recognise target sequences and cut DNA at or near these sequences. These sequences are called restriction sites.
They act as a defense mechanism against invading pathogens. However, they are routinely used in molecular biology labs to perform DNA technologies such as genetic engineering.
True or false: Euglena are examples of protists that can feed like an animal or use the energy of the sun to make food like a plant.
Answer:False
Explanation:
There are no man-eating plants or leaf-growing animals. The idea of an organism both photosynthesizing and hunting for food might seem strange, but this isn't science fiction. These organisms, examples of Euglena, are protists that can feed like an animal or use the energy of the sun to make food like a plant.
This statement is false. Euglena are not the examples of protists that can feed like an animal or use the energy of the sun to make food like a plant.
What are protists?A protist is any eukaryotic organism that is not an animal, plant, or fungus. While it is likely that protists share a common ancestor, the exclusion of other eukaryotes means that protists do not form a natural group, or clade.
Moreover, protists are any member of a group of diverse eukaryotic, predominantly unicellular microscopic organisms. They may share certain morphological and physiological characteristics with animals or plants or both.
Therefore, characteristics of protists: they are eukaryotic, which means they have a nucleus. Most have mitochondria. They can be parasites. They all prefer aquatic or moist environments.

WILL GIVE BRAINLIEST ANSWER. Which statement describes the relationship between breathing and cellular respiration in animals?
A. Carbon dioxide is inhaled and is a product of cellular respiration
B. Carbon dioxide is exhaled and is a product of cellular respiration
С. Carbon dioxide is exhaled and is a reactant of cellular respiration.
D. Cellular respiration and breathing are the same processes.
Answer:
B
Explanation:
The statement that describes the relationship between breathing and cellular respiration in animals is carbon dioxide is exhaled and is a product of cellular respiration. The correct option is B.
What is cellular respiration?Cellular respiration is a process of breakdown of food material and releasing energy into the blood. Oxygen is mixed with the food material and carbon dioxide is released out of the body.
Breathing is a process of taking in oxygen and taking out carbon dioxide from the body. Breathing is the first step of respiration, as oxygen is needed for the respiration process, which is done by breathing.
Carbon dioxide is a product of cellular respiration, and it is taken out of the body by breathing.
Thus, the correct option is B. Carbon dioxide is exhaled and is a product of cellular respiration.

how are two processes from photorespiration related?
Answer:
Several physiological processes may be responsible for linking photorespiration and nitrogen assimilation. Photorespiration increases availability of NADH, which is required for the conversion of nitrate to nitrite.
Answer:
Two molecules are produced: a three-carbon compound, 3-PGA, and a two-carbon compound, phosphoglycolate. ... Photorespiration results in a loss of 3 fixed carbon atoms under these conditions, while the Calvin cycle results in a gain of 6 fixed carbon atoms.
