if a cell more than doubled its size before dividing what would eventually happen to the cells?
Answer:
If a cell more than doubled its size before dividing, the daughter cells would be larger than the original cell. If this happened with each generation, cells would quickly become too large to live. Similarly, if a cell did not double its size before dividing, the daughter cells would be smaller than the original cell.

Hydrogen bonds allow two molecules to link together temporarily. Water molecules are made up of two hydrogen atoms and one oxygen atom, held together by polar covalent bonds. The polarity of the water molecule is what gives water its unique properties.
which of the following are the best sources of long-term, stored energy in our bodies?
Answer:
Protein and fats.
Explanation:
Protein and fats are the best sources of long-term, stored energy in our bodies because these sources for a long time and body used these sources when there is no food for the body. First, the fats are broken down and releases high amount of energy which is used in different activities. When all fats are used then body used proteins present in our body for the generation of energy.
Answer: Proteins or Fats

I need help asap it is past due pls give the definition of the following
Answer:
reactivity-In chemistry, reactivity is the impetus for which a chemical substance undergoes a chemical reaction, either by itself or with other materials, with an overall release of energy.
Tarnishing- is a thin layer of corrosion that forms over copper, brass, aluminum, magnesium, neodymium and other similar metals as their outermost layer undergoes a chemical reaction. Tarnish does not always result from the sole effects of oxygen in the air.
endothermic -(of a reaction or process) accompanied by or requiring the absorption of heat.
(of a compound) requiring a net input of heat for its formation from its constituent elements.
Rusting-deteriorate through neglect or lack of use.
exothermic-of a reaction or process) accompanied by the release of heat.
(of a compound) formed from its constituent elements with a net release of heat.

Reactivity: the state or power of being reactive or the degree to which a thing is reactive.
Tarnishing: lose or cause to lose luster, especially as a result of exposure to air or moisture.

Sustainability is how biological systems remain diverse and productive.
Ecological Footprint is the impact of human activities measured in terms of the area of biologically productive land and water required to produce the goods consumed and to assimilate the wastes generated.
Agriculture is the science of raising plants and/or animals for food, clothing or other useful products or the practice of cultivating the land or raising stock.
All cells of an organism are engaged in many different chemical reactions.
Answer:
Enzymes
Explanation:
All cells of an organism are engaged in many different chemical reactions. This fact is best supported by the presence in each cell of thousands of different kinds
The statement "all cells of an organism are engaged in many different chemical reactions" is definitely true.
What is a chemical reaction?A chemical reaction may be defined as a type of reaction in which one or more substances known as the reactants are significantly converted to one or more different substances known as the products.
Cells may be characterized as the fundamental structural and functional unit of life. All living organisms are made up of cells. These cells play specific functions within the living body in order to enhance their survival.
All cells of living organisms are busy with specific functions with respect to their characteristics and position in the living organisms along with biocatalysts known as enzymes.
Therefore, the statement "all cells of an organism are engaged in many different chemical reactions" is definitely true.

In order to come to the conclusion that their hypothesis is supported, what crucial step must a scientist perform? a)Gather information and do background research. b)Make observations and record the data. c)Communicate their results and allow peers to review their findings. d) Analyze their test results to look for patterns.
Answer:
A
Explanation:
i think
Answer:
[See Below]
Explanation:
✦ In science, we usually refer to the scientific method:
✧ Question - What do you want to learn more about? What are you trying to figure out?
✧ Research - Gather your information that relates to the topic.
✧ Hypothesis - Form an "educated" guess of what will happen, what the answer will be.
✧ Experiment - Using steps, test your hypothesis.
✧ Analysis - Review all the information you collected from the experiment. As well as a written account of what happened.
✧ Conclusion - Was your hypothesis correct or not? Explain.
✦ Now for your question, if we look at the above scientific method what can we inquire that you need to PROVE that you hypothesis is correct:
✧ Gather information and do background research - This is a step but it's not crucial to PROVING the hypothesis.
✧ Make observations and record the data - This is a step but it's not crucial to PROVING the hypothesis.
✧ Communicate their results and allow peers to review their findings - This is a step but it's not crucial to PROVING the hypothesis.
✧ Analyze their test results to look for patterns - Yes! This is probably the most crucial step besides the actual test itself. When you analyze your data you can figure out if what happened in the test was what you said would happen in your hypothesis.
So It'd be D, Analyze their test results to look for patterns.

Answer:
Viruses are not living things. One reason viruses are not alive is because they require a host to survive and reproduce. A second reason a virus is not alive is because they do not stimuli. A final reason that a virus is not alive is that they are not made up of cells. All living things can reproduce without a host, are made up of cells and react to stimuli except viruses, so they are not living.
explain why there are no giant cells. Use the terms diffusion, cell membrane and cell volume in your answer.

Answer:
A small amount of fat is an essential part of a healthy, balanced diet. Fat is a source of essential fatty acids, which the body cannot make itself. Fat helps the body absorb vitamin A, vitamin D and vitamin E. These vitamins are fat-soluble, which means they can only be absorbed with the help of fats.

Which of the following provide evidence that natural selection occurs in peppered moths?
A. Melanic moths become more abundant than light forms in polluted areas
B. Light moths become more abundant than melanic forms when clean air legislation is implemented
Answer:
B
Explanation:
When the moths camouflage with their surroundings, they are less likely going to be eaten by their predators. So therefore, more moths are going to want to mate with the darker moths that blend with their surroundings.
Camouflage protects moths from predators. Thus, darker moths that blend in will attract more mates. Therefore, option (A) is correct.
What is natural selection?Natural selection refers to the process in which different individuals with distinct phenotypes have variable rates of survival and reproductive success. The gradual shift over time in the heritable characteristics that are typical of a population is a crucial aspect of the evolutionary process known as evolution.
It is less probable that the moths' natural enemies will consume them if they are able to blend in with their environment and use camouflage. Therefore, a greater number of moths will seek to mate with the darker moths because these moths fit in better with their environment.
