When can a cell swell up ?
Answer:
Explanation:
The cell swells up when the concentration of water molecules outside the cell is more than the concentration of water molecules inside the cell. It is because the water moves from a region of higher concentration to a region of lower concentration due to osmosis. So the water molecules outside the cell will move inside the cell ( from higher concentration to lower concentration) and it will swell up.
This solution is known as hypotonic.
So the correct option is B.
Hope this helps
plz mark as brainliest!!!!!!
Answer: A
Explanation: When there is a higher concentration of water in the cell more than the surrounding area, then the cell tends to swell up, this is due to osmosis.

Explain how environmental and health costs are affected by the production of uses of goods and services in their marketplace.
Answer:
Demand and cost of a product is inversely proportional to each other. The environmental and health costs will also inversly proportioanl to the production of uses of goods and services in their marketplace.
It means, if there will be more production or uses of goods and services in the market, the cost of the environmental and health costs will decrease.
For example: if there are 4 to 5 general hospitals in an small area and people infected with partcular disease are more then the health cost in this area will be less or limited.
Which best describes when the body is working on counteracting an effect?
when hormone levels in the body are all equal
during a negative feedback loop
during a positive feedback loop
when the hypothalamus is signaling the pituitary gland
Answer: the answer is B or during the negative feedback loop.
Explanation: the body is trying to counteract the negative feed back.
During a negative feedback loop, the body is working on counteracting an effect. thus, option B is correct.
What are the differences between negative and positive feedback loops?Positive feedback loops amplify or exacerbate changes, moving a system farther from equilibrium and making it more unstable. Negative feedbacks tend to dampen or buffer changes; this tends to hold a system to some equilibrium state making it more stable.
A self-regulating system is a negative feedback loop, often known as an inhibitory loop. Increased output from the system restricts future production in a negative feedback loop. When the quantities of particular proteins or hormones in the body get too high, the body reduces their production.

C. Law of Segregation
D. Law of Multiple Alleles
Answer:
c. low of segregation is the correct answer
This principle states that alleles separate during gamete formation is Law of Segregation.
Option C is correct.
How do we explain?The Law of Segregation states that during gamete formation, the alleles of a gene segregate (separate) from each other, so that each gamete receives one allele from each parent and this means that each gamete will contain only one of the two alleles for a particular gene.
The Law of Segregation was first proposed by Gregor Mendel in 1865.

Which of the following statements is true? The rigidity of a cell wall causes plants to be sedentary. Primary cell walls are more rigid than secondary cell walls. Since they have cell walls, plant cells do not have cell membranes. A wilting plant will have a full central vacuole.
Answer:
The correct answer is : The rigidity of a cell wall causes plants to be sedentary.
Explanation:
Plant cells have an extraordinary organelle present outside of cell membrane known as a cell wall, which makes the cell more rigid and strong. The primary capacity of a cell wall is to provide structural support.
It additionally gives the plant a specific level of inflexibility, which permits it to become extremely tall without falling under its own weight. The drawback is the absence of versatility Which is the reason plants are inactive and incapable to move.
Thus, the correct answer is : The rigidity of a cell wall causes plants to be sedentary.

Homeostatic Imbalance and Disease. Sometimes homeostats fail to perform properly. This can cause homeostatic imbalance, a condition in which variables in the internal environment are no longer maintained within normal ranges.
Explanation:
when you get sick and have a fever, what internal condition has changed it ultimately change the body's homeostasis. The body is unable to maintain the equilibrium of internal environment will lead to homeostatic imbalance.
What is homeostatic imbalance ?Homeostasis is mechanism where our body maintain balance and equilibrium which can be characterized physiologically or psychologically.
It is extremely important as it has a vital in maintenance of glucose levels, osmoregulation, regulate hormones, and body temperature.
It is otherwise called as thermoregulation as the body temperature is maintained by this process.
For example a person with cold, shiver to warm up while a person with high body temperature, sweat a lot in order to attempt cool their body.

After one round of DNA replication, _____________ of the DNA will contain only 14N, _____________ of the DNA will contain only 15N, and _______________ of the DNA will be of an intermediate density.
Answer:
After one round of DNA replication, none of the DNA will contain only 14N, none of the DNA will contain only 15N, and all of the DNA will be of an intermediate density.
Explanation:
In order to rule out the conservative model of DNA replication and discover that it in fact a semi-conservative model, this technique was employed to check for what ratio of N15 and N14 was present in cells that had undergone the process of replication. The former would've resulted in equal densities of both N14 and N15.
