Water is the most abundant molecule found in living organisms. Most mammals, in fact, are approximately 70% water by weight. About two-thirds of this water is present inside cells. The other one-third is present outside cells (e.g., in blood plasma or other body fluids). Why is water so important to cells?
Answer:
Water is an essential constituent of the protoplasm of living cells because it is directly involved in countless biochemical reactions like photosynthesis and respiration. Without it cells couldn't move waste and by-products, take in nutrients, perform intracelluar transportation, functioning and signalling
Explanation:
Which gas is removed from the atmosphere during photosynthesis?
Hydrogen
Carbon dioxide
Oxygen
Nitrogen
Answer: carbon Dioxide
Explanation: With water carbon dioxide is a byproduct

When you want to move a part of your body, your brain sends a signal to
the muscles....
The muscles Contract and relax randomly
Contract and pull on bones directly
Contract and pull on tendons, which pull on the bones
Answer:
Contract and pull on tendons, which pull on bones
Explanation:
Muscles don't attach directly to bones. The tendons throughout our body serve as a connective tissue, connecting the two. Skeletal muscles, which seem to be attached to bones, are still only held there with the help of muscles.

how does air pressure affect weather
Answer:
Hewo, Kiluawa (sorry if i spelled it wrong)
Explanation:
High Pressure
Basically, high pressure occurs in an area if the atmosphere over that particular area becomes heavier. As a result, the heavy air above will come down to the Earth’s surface. And the air present in that area will move away to create space for the heavy air.
Commonly, the warmer months experience high pressure. You’re more likely to enjoy a comparatively dry and stable weather pattern in those months. Besides, you’ll find the skies in high pressure areas very clear. You’ll also feel a gentle breeze there that will cool down the surrounding areas.
Low Pressure
On the other hand, the air above a low pressure area is comparatively much lighter than the air below. As the heavy air on the Earth’s surface cannot go further below, it pushes away the lighter air above. As a result, a vacuum is created on the surface level and the air in the surrounding areas rushes towards it to fill up the void space.
Meanwhile, the rising air starts to cool down and form clouds in the sky. These clouds then come down to the Earth in the form of rain. Sometimes, snow is also formed depending on the temperature of the surrounding areas.
In general, colder months of the year experiences more low pressure situations. By now, you probably can guess why. The cold air on the surface level is heavier than the air above. And these low pressure areas are the reasons behind unstable weather conditions like snow, ice, rain, storm, etc.

If a DNA strand contains 26% thymine, what percent adenine will there be in the
same DNA molecule?
Hint: use Chargaff's Rules
24%
27%
26%
23%
Answer:
26%
Explanation:
Adenine and Thymine are pairs. Therefore, they must have the same amount.
It must always equal 100% and base pairs always have the same amount. So in this case Adenine and Thymine would be 26% and Guanine and Cytosine would be 24%.
Test question: If a DNA strand has 10% Guanine how much Adenine would there be?
Answer: G-10, C-10, A-40, T-40= 100%

Some individuals of a particular species of sea bird underwent a genetic mutation that resulted in larger beaks. The larger size of beaks helped
these birds to break open dams and other mollusks for food. It also helped them defend themselves against predators. After many generations,
almost all of the birds in the population had big beaks. For which two reasons did this phenomenon occur?
A. natural selection
B. mechanical Isolation
C. prezygotic barriers to reproduction
D. high genetic variation in the species

Explanation:
in order to perform, a chemist needs an element that has similar properties to potassium (K) but has a lower atomic mass. which element should the chemist select for the experiment?
A. Robidium (Rb)
B. Sodium(Na)
C. Magnesium(Mg)
D. Calcium(Ca)
The element needed by the chemist to perform the experiment with similar properties to that of potassium, while having lower atomic mass is option B. Sodium.
If we take a look at the periodic table, we can see all the elements that share properties with potassium are located within the same column. Some examples are :
SodiumRubidiumCesium LithiumOf the elements listed, only two are found within the options for this question, which means that we can discard option C and D.
We can then proceed to analyze the atomic mass of each element in an attempt to choose the option with a lower atomic mass than Potassium. Option A, Rubidium, has an atomic mass that is much higher than the 39 of potassium, which means we can discard option A. The correct choice is option B, Sodium , since it shares similar properties and has an atomic mass of 22.
