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:
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%

Answer:
does this help ?
Explanation:
a large patch of warm water developed off the coast, creating a catalyst that has further changed this underwater environment. The persistent warmer sea temperatures stress the kelp forests to the point that growth and reproduction have slowed dramatically and caused damage to remaining fronds and tissue.

People’s choices can have a positive or negative effect on their health. Describe one positive choice and one negative health choice a person could make. Be sure to explain how each could impact an individual’s health and, if applicable, the health of others.
People nowadays try to live a healthier lifestyle. The positive and negative choices depends on some aspects. For instance, a person with a normal weight or thin can be unhealthy . Health also includes the good amount of nutrition and exercise not only the weight. A good choice a person can make is exercise more and intake good amounts of nutrition. A bad choice is not exercising and not having adequate intake of nutrition. Some people tend to lose weight by quiting some nutrients which will have a bad effect on their health since all the nutrients are important for the body and avoiding some nutrients can cause deficiency. The best thing to do is diet on calories, a type of diet from which you can eat anything(all types of food including vegetables and fruits ) but measure your calorie intake , with this a person has a higher chance of losing weight and being healthy. Exercise too is an essential factor needed for a healthy lifestyle. If a person has a lifestyle which they need to move alot(jobs including sports etc) then you can say its enough but if not a person must do exercise at least twice or more a week for better health. Quitting smoking and drugs of course has a good effect.

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.

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.
