Answer:

Two species (B & C) are more closely related to one another than either one is to a third species (A) if, and only if, they share a more recent common ancestor with one another (at Time 2) than they do with the third species (at Time 1).

Explanation:

B and C species are closely related in this phylogenetic tree. A diagram that shows the evolutionary relationships between different species or groups of animals is called a phylogenetic tree.

By showing the branching points where species diverged from a common ancestor, it exemplifies the shared ancestry and evolutionary history of species. The arrangement of species on branches that have a recent common ancestor reflects the degree of relatedness between organisms.

Closely related species tend to cluster together on such branches. Phylogenetic trees are constructed based on similarities and differences in genetic structure, physical characteristics, or other traits observed in different animals. They are important tools in the discipline of evolutionary biology to study patterns of variation and the development of life on Earth.

Answer:

They need food in order to gain the initial energy they need.

Explanation:

Plants unlike humans don't get food by primary sources (aka, hunting). instead they retrieve their food from the suns rays. Without the suns rays they are able to convert this energy into glucose for themselves, and will essentially die because they do not have that source of food to give them the energy they need to survive.

Answer:

Small, nonpolar molecules (ex: oxygen and carbon dioxide) can pass through the lipid bilayer and do so by squeezing through the phospholipid bilayers. They don't need proteins for transport and can diffuse across quickly.

Explanation:

The channel proteins act like doors through the cell membrane.

They allow large polar molecules to move in and out of the cell.

The process is called passive diffusion or passive transport, because it does not need energy.

Sometimes the protein changes shape to help the polar molecules move through the channel.

It often uses a gated pore mechanism, in which the channel is never completely open.

Answer:It provides support.

Explanation:

so it things cant get in or out

Answer:

It involves facilitated diffusion.

Explanation:

Facilitated diffusion uses channel proteins. Channel proteins allow substances to travel through a membrane going with the gradient. Since active transport goes against the gradient, facilitated diffusion would not be a characteristic of it.

Answer:

Urey and miller cooked a "primordial soup" with Hadean gases, water and electricity to make glucose, acetic acid, amino acids and lipids.

Explanation:

In the Miller-Urey experiment, the aim was to reproduce the conditions of the earth before the existence of life, with the objective of demonstrating the formation of organic matter from inorganic molecules.

The scientists took water and gases present in the Hadean eon —previous to the existence of life— such as methane, carbon dioxide, hydrogen, nitrogen and even ammonia, the primordial soup. This mixture was subjected to electrical discharges, inside closed containers.

The results were some organic molecules, including glucose, acetic acid, amino acids and fatty acids. In these results the presence of macromolecules, such as proteins or nucleic acids, is not appreciated, however it was a significant contribution to the knowledge of the origin of life on earth.

osmosis

Explanation:

The movement of water from an area of high water concentration to an area of low water concentration is called as Osmosis. Thus option D is correct.

The process in which solvent molecules pass from a lower concentration based solution to a higher concentration solution through a semipermeable membrane called as osmosis.

It is a passive process as no external energy is needed.

When a living plant cell kept in a sugar or salt solution, water diffuses from the cell sap out through the cell membrane called as ex-osmosis.

The cell causes shrinkage of the protoplasm due to water loss, where the cell undergo a condition called as plasmolysis or necrosis.

When the plasmolysed cell is placed in distilled water, the cell regains it’s turgidity and also the original shape and size by a process called endosmosis.

This condition is called deplasmolysis or cytolysis. Thus option D is correct.

Spring and Neap rides occur twice a month

Spring and neap tides occurs twice a month.

A neap tide refers to a period of moderate tides when the sun and moon are at right angles to each other. A spring tide is a common historical term that has nothing to do with the season of spring.

In the period between the two spring tides, the moon faces the Earth at a right angle to the sun. When this happens, the pull of the sun and the moon are weak. This causes tides that are lower than usual. These tides are known as neap tides.

Spring tides have higher high tides and lower low tides whereas neap tides have lower high tides and higher low tides. Hence, the range (difference in water level between high and low tide) is much larger in a spring tide than in a low tide.
