What happens to an air mass as it moves away from its source region? Pls help lol ASAP

1 answer:

3 0

A cold air mass flowing away from its source region over a warmer surface will be warmed from below making the air more unstable in its lowest layers. A warm air mass flowing over a colder surface is cooled from below and becomes stable in its lowest layers.

If i am wrong please let me know!

What type of bacteria can be found in pairs, chains, squares of four, cubes of eight, or grape like clusters?

liberstina [14]

Coccus-shaped bacteria can be found in pairs, chains, squares of four, cubes of eight, or grape like clusters. More specificially, this type of bacteria found in pairs is called diplococcia, in chains is called streptococci, in squares of four is called tetrads, in cubes of eight is called sarcinae, and in grape like clusters called staphylocci.

IF most of the energy we use on earth comes from the sun –how does that energy (light and thermal) end up

____ [38]

Answer:

1: Chemical Energy

2: Kinetic Energy

3: Electrical Energy

4: Mechanical Energy

Explanation:

1: The energy held in food is called chemical energy. It is a form of potential energy held within chemical bonds between atoms.

2: When flowing water is captured and turned into electricity, it is called hydroelectric power or hydropower. There are several types of hydroelectric facilities; they are all powered by the kinetic energy of flowing water as it moves downstream.

3: The power for lights and stuff is Electrical Energy, ofc :]

4: The chemical energy in the food gets changed into the mechanical energy of moving muscles.

Hope this helps!! :D

kolbaska11 [484]

Answer:

Option 1, a charged end and a noncharged end

Explanation:

Complete question

If a small droplet of ordinary fat is suspended in water, the fat molecules form a "ball of spaghetti" with no particular orientation. But if a droplet of phospholipid molecules is put in water, all the molecules point outward, toward the water. Phospholipids are forced into this orientation because phospholipids have _____

a charged end and a noncharged end
three fatty acid molecules, all pointing in different directions
two fatty acid molecules pointing in different directions
both a saturated fatty acid and an unsaturated fatty acid
two charged ends

Solution

The structure of phospholipids consists of the following groups and molecules –

a) A glycerol molecule

b) Fatty acids (2 in numbers) – It is hydrophobic as it is uncharged and non polar in nature

c) Phosphate group (with alcohol) – It is hydrophilic as it is negatively charged and polar in nature.

When the phospholipids are placed in water, the molecule rearranges itself in a way that the hydrophobic head face inside and the hydrophilic head face outside thereby forming micelles.

Hence, option 1 is correct

Katen [24]

If one wishes to clone a gene using typical restriction endonucleases, how does the restriction endonuclease identify the appropriate cut sites in the genome using the palindromic sequence.

Restriction endonucleases are a family of enzymes usually found in bacteria that cuts DNA at a specific sequence called recognition site. There are three type of restriction endonuclease Type I, Type II, and Type III.

Each endonuclease recognizes a particular sequence called palindromic sequence which is a sequence that reads the same sequence in both the strands either reading from the 3 prime end or 5 prime end.

The endonuclease cuts the palindromic sequence in such a way that it produces sticky ends.
