What is the major consideration in setting the lower limit of cell size?
A. The cell size must be small as to fit all the processes and structures to support life.
B. The cell must be large enough to fight the pathogens.
C. The cell must be large enough to attach to a substrate.
D. The lower limit should be small enough for the cell to move in the fluid efficiently.
Answer:
c
Explanation:
The lower limit should be small enough for the cell to move in the fluid efficiently. Therefore, option (D) is correct.
The major consideration in setting the lower limit of cell size is the need for the cell to move in fluid efficiently. As cells become smaller, their surface area-to-volume ratio increases, allowing for more effective exchange of nutrients, gases, and waste products across their membrane.
This is particularly important for cells living in fluid environments where diffusion plays a crucial role in these exchanges. Small cells have an advantage in absorbing and expelling substances due to their larger surface area relative to their volume. Therefore, the efficiency of nutrient uptake and waste removal becomes more effective with smaller cell sizes, making efficient movement in fluid environments a significant factor in determining the lower limit of cell size. Thus, option (D) is correct.

When Emma first began dancing, her movements were ______ and awkward. Now, after several months of practice, Emma is able to produce fluid, smooth movements as a result of which of the following?
*all of the above is correct
Answer:
All of the above is the correct answer
Explanation:
Which of the following is associated with plates moving away from each other? a. Rifts b. Subduction zones c. Faults d. All of the above.
Answer:
a. Rifts
Explanation:
A fault (c) happens at all plate boundaries, so while this is true, it is not the most correct. A subudction zone (b) is where Earth's tectonic plates dive down into the mantle, so this does not answer our question. A rift, in general, is a crack, split, or break in something. A rift in plate tectonics is when plates are moving apart from each other, caused be tension, so a is our answer.

Define negative feedback in biology
Answer:
A negative feedback loop occurs in biology when the product of a reaction leads to a decrease in that reaction. In this way, a negative feedback loop brings a system closer to a target of stability or homeostasis
Explanation:
Negative feedback occurs when some function of the output of a system, process, or mechanism is fed back in a manner that tends to reduce the fluctuations in the output, whether caused by changes in the input or by other disturbances

Answer:
We have a lot of similar genes to those of animal kin.
Explanation:
The genes of humans and animals show more than 50% similarity and conclude the same ancestral origin.
What are genes?The gene can be described as the hereditary unit that results in the make-up of proteins for the functioning of the body.
The genes are hereditary and evolution there results in the change in the genotype and thereby phenotype with mutations.
The genes of humans and animals result in the similarity of more than m 50%. This concludes that there has been the presence of the same ancestral origin for the animal and humans.
The genetic similarity between humans and the animal species results in the conclusion of humans belong to the animal kingdom and have the same ancestral origin.

the small bones in the middle ear that transmit vibrations to the inner ear
Answer:
, yes..............
Explanation:
because the vibrations are transmitted to the inner ear after the bones amplify it
Ossicles are the body's tiniest bones. the malleus (hammer), incus (anvil), and stapes (stirrup). Ossicles amplify sound.
What are ossicles?Ossicles are very little bones; in fact, they are the tiniest bones in the entire human body. The malleus (hammer), the incus (anvil), and the stapes are the names of the three bones because of the forms they make (stirrup). The sound is amplified even further by the ossicles.
In order to reach the eardrum, sound waves must first enter the outer ear and then proceed via the ear canal, which is a very short conduit. The incoming sound waves cause the eardrum to vibrate, and the eardrum in turn transmits these vibrations to three very small bones located in the middle ear. The malleus, incus, and stapes are the names given to these three bones.
Hearing is dependent on a series of intricate steps that convert sound waves in the air into electrical impulses. These steps are necessary for hearing.
