How do oceans contribute to creating winds?
A.Ocean currents create momentum that pull air with them.
B.Ocean water vapor pushes air causing it to flow in different directions.
C.Ocean energy is transferred to or from the air creating density differences.
D.Ocean water vapor eventually condenses into clouds and wind.
Answer:
Explanation:
Ocean energy is transferred to or from the air creating density differences.
Oceans contribute to creating winds as ocean energy is transferred to or from the air, creating density differences. The correct option is c.
What is ocean energy?The ocean waters are continually changing. Wind, water salinity, temperature, ocean floor topography, and the earth's rotation all influence ocean current flow patterns.
The majority of ocean currents are caused by wind and solar heating of surface waters near the equator, while some are caused by density and salinity fluctuations in the water column. In contrast to tidal currents along the shore, ocean currents are typically consistent and travel in one direction.
The transfer of energy from the ocean to the atmosphere causes the atmosphere to cool. The energy travels in a disturbance, which in an ocean is a wave, therefore the wave generates energy and transports it through the water.
Therefore, the correct option is C. Ocean energy is transferred to or from the air, creating density differences.

what are the scientist doing incorrectly? what could they do to make their work in the lab safer? why is it important to follow these procedures? part c
Answer:
What the scientist is doing incorrectly is placing test tubes in a cabinet in disorderly form, without protective or biosafety equipment, having other tubes loose on the shelf, which can fall, break and spill their contents.
Explanation:
The image scientist is doing an incorrect procedure because
He is handling laboratory material without protection. He has messy tubes on the shelf of the cabinet, which can be chewed and broken, spilling their contents. He is not using a ladder to reach the highest spaces in the cabinet and place the tubes.What could they do to make their work in the lab safer?Use biosafety equipment to handle containers with chemical or biological substances.Keep the tubes in racks or tube holders to prevent them from falling accidentally.Place the tubes in an orderly manner, using a ladder to place the tubes at the top of the cabinet.Why is it important to follow these procedures?It is important to follow these procedures to protect his body from accidental spills, as well as to avoid breaking containers and contaminating the work space.

This transportation process requires the cell to move particles from low concentration to high concentration. active transport facilitated diffusion osmosis diffusion
Answer:
During active transport, substances move against the concentration gradient, from an area of low concentration to an area of high concentration. This process is “active” because it requires the use of energy (usually in the form of ATP). It is the opposite of passive transport.
Explanation:
This may help you out! :)

Explanation:
the number of two digit is equal to four times the sum of digits. if the product of digits is 8 .find the number.
Answer:
I think you are only intended to find
24
Explanation:
10x + y = 4(x + y) Remove the brackets
10x + y = 4x + 4y Subtract 4x from both sides
10x - 4x + y = 4x - 4x + 4y Combine like terms
6x + y = 4y Subtract y from both sides
6x + y - y = 4y - y Combine
6x = 3y Divide by 3
6x/3 = 3y/3
2x = y
Put this result in the equation below
x*y = 8
x(2x) = 8
2x^2 = 8 Divide by 2
2x^2/2 = 8/2
x^2 = 4 Take the square root.
√x^2 = √4
x = ± 2
y = 2*x = ±4
Answer
The plus answer for x and y is the one we'll see about first.
10x + y = 20 + 4 = 24
24 =? 4(2 + 4)
24 =? 4*6 = 24
The product of it's digits = 2 * 4 = 8.
24 is definitely one answer.
========================
What about -2 and - 4
-24 = 4(-2 + -4)
-24 = 4*-6 = -24

Both starch and cellulose are polysaccharides made of individual glucose molecules. Why then can humans digest starch but not cellulose
Answer:
Starch and cellulose are two very similar polymers. In fact, they are both made from the same monomer, glucose, and have the same glucose-based repeat units. ...

What type of cells reproduce by mitosis
In mitosis, a cell duplicates all of its contents, including its chromosomes, and splits to form two identical daughter cells, same number chromosomes.
What is chromosome ?
A chromosome is defined as a thread-like structure present in the nucleus of cells such as both prokaryotic and eukaryotic cell and it is made of a molecule of DNA (Deoxyribonucleic acid) and histone proteins.
It is composed of three components, DNA, proteins and RNA, amount of the DNA content ranges from 30 to 40 %, the amount of proteins from 50 to 65%, and small amount of RNA from 1 to 10%.
Two types of protein present in DNA such as histone and non-histones proteins, histone constitute large amount (90% of total protein), whereas non-histone is present in small amount (around 10% of total protein).
The histone protein is basic, whereas, the DNA is acidic, so it can be neutralized; DNA in chromosome is present in two forms such as Euchromatin and Heterochromatin.
