Biology
1 answer:
Travka [436]3 years ago
6 0

Answer:

Air pressure is the weight of air molecules.

Explanation:

Air pressure can be described as the force generated by the weight of air on the surface of the Earth. The size and number of the air molecules determine the air pressure.

When the number of molecules in the air increases, it generates more force on the Earth's surface and we say that it is regarded as a rise in the atmospheric pressure. A mercury barometer is a device which is used to measure the air pressure.

A hypothetical three-step metabolic pathway consists of the intermediates W, X, Y, and Z, and the enzymes that catalyze the reac
GenaCL600 [577]

Answer:

ZBWCYAX

Explanation:

Equation for the intermediates: Z↔W↔Y↔X

1) B catalyzes the breakdown of Z, therefore inhibiting B leads to the build up of Z.

2) If enzyme C is inactive then the organism will not  receive Y to grow, thus Y is a by-product of C.

3) If A is inhibited then W, Y and Z build except for X, thus it make sense that A catalyzes a reaction that leads to X as a by-product.

4) Inhibiting C leads to the reaction toward making Z and W, thus it catalyzes the breakdown of C directly and Z indirectly.

zheka24 [161]
A community refers to the total number of populations that inhabit a specific location or area. This is part of the levels of organization of life. Arranged from the least complex to most complex it falls 8th in the category. Below are the organization of life:<span>

a. Organelles - the basic part of a living organism. It refers to the different structures of the cell, whether prokaryotic or eukaryotic. (Ex. Mitochondria, nucleus)
b. Cells - building blocks of life that are composed of different molecules responsible for the function of an organism. (Example: prokaryotic, eukaryotic cells)
c. Tissues - combinations of cells that carry out a specific function in an organism. (Example: Human skin)
d. Organs - collections of tissues that perform specific functions. (Ex. heart, lungs)
e. Organ Systems - composed of interconnected organs that function as a whole. Many organisms, particularly mamamals, are composed of organ systems. (Ex. respiratory, circulatory systems)
f. Organisms – individual entities that specifically make-up a population. (Ex. Each tree in the forest is an organism, each animal in sea is an organism)</span>
g. Population – species living within a specific location. It could be the same or different species that inhabit a place. (Ex. Birds are species in the forest as well as bears)
h. Community – refers to the total number of populations that inhabit a specific location. (Ex. All of the trees, insects, birds that inhabit the forest are a community)
i. Ecosystem – consists of all living things that function together as a group which also includes the non-living parts of the environment. (Ex. Rain water, nitrogen in the soil)
<span>j. Biosphere – the highest organization of life that consist of all the collection of ecosystems in the planet. It includes the land, air, water, even the atmosphere of the planet. </span>

Describe two ways polar bears are well adapted to surviving during the Arctic winter.
cricket20 [7]
They are well at surviving because of their thick white coat. The white fur helps them blend in with the snow and ice. The polar bear also has a layer of fat under their skin so they can survive harsh temperatures.
