Answer:
Energy from the sun allows the plant to grow and make its own food.
Explanation:
From this image, we clearly see the leaves exposed to sun which supplies solar energy to the plant.
Plants are capable of producing their food from inorganic chemical sources. In the process of photosynthesis, plants takes carbon dioxide and water in the presence of sunlight to manufacture their own food. The food provides energy that allows the plant to grow.Answer:

The corresponding mRNA to 5'AAAACTGTGCAT3' is
3'UUUUGACACGUA5'.
What is nucleotide sequence?Nucleotides are the bases that are arranged in a specific way, and it joins the two strands of DNA and RNA.
In DNA, four nucleotide bases are present AT and GC. They are attached to each other.
In RNA, the same bases are present but instead of T, U uracil is present.
When reading the DNA, the RNA bases complimentary join with the bases of DNA.
Thus, the corresponding mRNA sequence is 3'UUUUGACACGUA5.

A pH below 7 is acidic and a pH above 7 is basic, and a pH of 7 is neutral.
when is the energy source used to fuel photosynthesis
Answer:
Photosynthesis, process by which green plants and certain other organisms use the energy of light to convert carbon dioxide and water into the simple sugar glucose. In so doing, photosynthesis provides the basic energy source for virtually all organisms.

According to Coulomb’s law, what will happen to the electric force between
two identical negative charges as they move closer together?
A. Fe will become negative and decrease in magnitude.
O B. Fe will stay negative and increase in magnitude.
C. Fe will stay positive and increase in magnitude,
D. Fe will become positive and decrease in magnitude.
Answer:
C. Fe will stay positive and increase in magnitude.
Explanation:
Coulomb's law states that the force of attraction of repulsion between two charged particles is directly proportional to the magnitude of their charges and inversely proportional to the square of the distance of separation between them.
This means that if the size of the charges are large, the force acting on them will be large as well. Also if the distance between the two charges increases the force decreases. However, the force increases when the distance of separation decreases.
Like charges repel, therefore, two negative charges brought together will repel each other, and the distance between the two charges decreases, the force will increase in magnitude. Forces of repulsion are considered positive, therefore, the force, Fe, will stay positive and increase in magnitude.

Which of the following is true about waves?
A.
They are always visible.
B.
They always move matter.
C.
They carry energy.
D.
They can only travel though outer space.
Answer:
c. they carry energy is the answer
Answer:
C. they carry energy
Explanation:
Energy can be carried from one place to another by waves, including water, light, and sound waves. Waves are oscillating disturbances that travel through but do not move matter.
Infrared radiation escaping from hot coals is an example of invisible waves carrying energy. This energy can be felt as heat.

Which subatomic particles are found in the nucleus of an oxygen atom?
F Neutrons and Electrons
G Electrons and Protons
H Protons and Neutrons
J Protons, Neutrons, and Electrons
Answer:
the answer is protons and neutrons
Explanation:because
The subatomic particles are found in the nucleus of an oxygen atom are Protons and Neutrons. Thus, option H is correct.
What are subatomic particles?An electron is defined as a subatomic particle which is charged negatively either bound to an atom or not it means free. The nucleus of an atom is made up of electron, proton and neutron. The electron is a basic particle and electron is not made of anything.
The nature of electron is free it means they are present freely in nature and consist of an atom.The main function of electron is that they play the role of negatively- charged component of an atom.
The electrons are primary source of current conducting and electrons number as well as atomic number of an element is always same or equal. There is no size of electron but the mass of electron is 9×10^-31.
Therefore,The subatomic particles are found in the nucleus of an oxygen atom are Protons and Neutrons. Thus, option H is correct.

the relation between stability and solubility
Answer:
2
Nobody is able to foresee the solubility of a product. There are some experimental rules, but they all have exceptions, that nobody is able to explain.
Just have a look on the Calcium salts made with the halogens (F, Cl, Br, I). There is a nice analogy among Cl, Br and I, but not F. Look ! The Calcium chloride CaCl2, bromide CaBr2 and iodide CaI2 are all extremely soluble in water. They are all soluble in less than their weight of water. But calcium fluoride CaF2 is among the least soluble product on Earth. The principal mineral for Fluoride is CaF2, and it can be found everywhere at the surface of the Earth. If this mineral would have been at least a little soluble in water, the rains would have washed away this mineral in the geological times. Why is there such a huge difference between calcium fluoride and the other halogenides ? Nobody knows !
Another example. Potassium perchlorate is the only potassium salt which is very weakly soluble in water. By comparison, Sodium perchlorate is extremely soluble in water. Why? Another example: the number of Silver compounds which are soluble in water is limited. In organic solvents, it is even worse. But the Handbook of Chemistry and Physics says that Silver perchlorate is soluble in toluene. Why? Nobody knows.
From time to time there are articles published in journals like the Journal of Chemical Education. The author is proud of displaying a theory filled with new parameters, for explaining the solubility of quite a lot of chemicals. But there are always exceptions, that he regrets not to be able to explain.

Irradiated food has molecules that undergo transmutation,
Od
Answer:
b . Irradiated food is shown to not be radioactive.
Explanation:
If it can be proven that irradiated food is not radioactive, then it will effective dispute the idea that irradiated food are less safe to eat.
An irradiated food is one in which ionizing radiations have been employed to improve food quality. Thus, bacteria and other food spoilers can be exterminated from the food. Most irradiated food do not contain radiation and are fit for consumption.If it can be proven, that this is true, then it will challenge the idea that irradiated foods are not safe.
