b. future perfect
c. future progressive
d. future perfect progressive
being pumped through ion channels.
B)
active transport through protein channels.
C)
passive diffusion through the lipid bilayer.
D)
facilitated diffusion through protein channels.
proteins are used to help move molecules more quickly. It is a process called facilitated diffusion. It could be as simple as bringing in a glucose molecule. Since the cell membrane will not allow glucose to cross by diffusion, helpers are needed. so the the correct chioice is D
B. A cell
C. An organism
D. All the above
Answer:
Species C.
Explanation:
The bands of the unknown species most closely align with those in the Species C column.
To identify the closest relative to an unknown species, scientists utilize phylogenetic trees and genetic analyses, which suggest that species positioned nearer to each other, like species D and E, are more genetically similar due to their recent common ancestry.
To determine the most closely related species to an unknown species, scientists often use phylogenetic trees and genetic analyses. A phylogenetic tree showcases the evolutionary relationships among various species, suggesting how recently species have diverged from a common ancestor. If performing a genetic analysis on species, it is expected that species that are positioned close to each other on the tree — such as species D and E — will share more genetic similarities, due to a more recent common ancestor. On the contrary, species that are positioned further apart, such as species A and B relative to species D and E, would share fewer genetic similarities as they would have diverged earlier in the evolutionary timeline.
An accurate phylogenetic tree based on certain characteristics like the circulatory system can elucidate the phylogeny within vertebrates. Additionally, dissecting and analyzing the digestive system of a new species can provide insights into its relatedness to known species, depending on which animals have a similar digestive configuration. Finally, cataloging and understanding biodiversity, including prokaryotic species, is essential as species extinctions accelerate, highlighting the significance of studying evolutionary relationships to comprehend the full tapestry of life on Earth.

Answer:
Cells are small because they need to keep a surface area to volume ratio that allows for adequate intake of nutrients while being able to excrete the cells waste. That is why the cell needs to be small. The smaller it is, the larger the surface area to volume ratio is. ... This is why cells are so small.
explicación:
The important point is that the surface area to the volume ratio gets smaller as the cell gets larger. Thus, if the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume. ... That is why cells are so small.
Cells are small to have a high surface-to-volume ratio and efficient exchange of materials with their environment.
All cells are very small because they need to have a high surface-to-volume ratio. The surface area of a cell determines the amount of substances that can enter or leave the cell, while the volume of the cell determines the amount of metabolic activity that can occur. By being small, cells can efficiently exchange materials with their environment and carry out essential functions.
For example, red blood cells are small to pass through the narrowest capillaries and transport oxygen to different parts of the body. Bacteria are also small to facilitate their nutrientuptake and waste removal.
Furthermore, the small size of cells allows them to have a faster rate of diffusion, which is important for the exchange of gases, nutrients, and waste products across the cell membrane.
