The correct answer is filtration.

The small molecules can cross in and out of the capillaries through facilitated or simple diffusion. However, the majority of the flow of capillary and tissue fluid takes place through the process of filtration and reabsorption. Filtration refers to the movement of the fluid out of the capillaries and is mediated by the capillary hydrostatic pressure.

How can you see change over time using topographic maps and satellite images?
Alexus [3.1K]

Topographic maps and satellite images

Explanation:

A topographic map represents earth's surface features like land forms and structures, rivers and lakes, mountains and hills, elevations and other natural features along with man-made artificial features like cities, buildings, monuments, roads, bridges etc. These are formed by contour lines.

Topographic maps are printed with revision dates to observe the changes happening on the Earth's surface. Various land forms keeps changing due to natural and man-made causes and these needs to be updated accordingly to provide accurate details.

A satellite image provides details of the earth aerially from space. These provides details of a land form or any earth structure currently.

By comparing with older satellite images or topographic maps with the current one, the changes which occurred over time can be observed.

According to the competitive exclusion principle, two species cannot continue to occupy the same A) habitat. B) niche. C) territ
levacccp [35]

Answer:

Niche

Explanation:

Niche basically is the lifelihood of a species that involves feeding on what, drinking from what....

If both species are competing for the same resources, they would compete until a certain species is eradicated. (think of it as 2 species of ants in 2 colonies that are close to each other, take the same leaves, prey and stuff. They would fight with each other in other until one colony is eradicated.) hence, unless a species and adapt and change its niche, both species would fight until one is eliminated. Thus, the principle states that 2 species cannot continue to occupy the same niche, not living environment.

DNA within the cell is wrapped around nucleosomes to form chromatin. When chromatin is in the form of a 30 nm fibril, how many c
vodomira [7]

Answer:

The correct answer is option b. "20 H1, 40 H2A".

Explanation:

Chromatin is a complex that protects and condenses the genetic material comprised of DNA and proteins. When chromatin is in the form of a 30 nm fibril, nucleosomes have a regular positioning along the DNA. This means that each nucleosome is associated with a single H1 molecule. Therefore a chromatin containing 20 nucleosomes will have 20 copies of H1 and 40 copies of H2A, because each nucleosome has 2 copies of the core histone H2A.

kogti [31]
Epiphyseal plate is the structure within a bone that contains cartilage cells that divide and increase the size of the bone until adulthood.

The epiphyseal plate, also known as epiphysial plate,or physis, or growth plate, is a hyaline cartilage plate in the metaphysis at each end of a long bone or diaphysis. The plate is found in children and adolescents; in adults, who have stopped growing, the plate is replaced by an epiphyseal line<span>.</span>
