What is the energy source that allows photosynthesis to occur?
Answer:
[tex]\boxed {\boxed {\sf The \ sun }}[/tex]
Explanation:
Photosynthesis is a special process that certain organisms (plants, algae, and some bacteria) undergo to create "food".
This turns light energy, carbon dioxide, and water into glucose and oxygen. The glucose becomes the food for the organism, because it is turned into ATP during cellular respiration. The ATP is energy that fuels the processes, like growth, repair, and transport.
This process occurs because of the sun. It provides the light energy needed for the reaction. Organelles inside of the cells, called chloroplasts, contain a pigment (chlorophyll) that captures this energy.

Molecules of DNA are composed of long chains of?
two long polynucleotide chains
A DNA molecule consists of two long polynucleotide chains composed of four types of nucleotide subunits. Each of these chains is known as a DNA chain, or a DNA strand. Hydrogen bonds between the base portions of the nucleotides hold the two chains together
Molecules of DNA are composed of long chains of nucleotides.
What are nucleotides?Nucleotides are the building blocks of DNA and RNA adenine (A), thymine (T), guanosine (G), and Cytosine (C. In RNA, uracil (U) is present instead of thymine.
The pentose sugar is the ribose sugar in RNA and deoxyribose sugar in DNA. In deoxyribose sugar, oxygen is absent from the 3' carbon.
Phosphate groups are attached through the 5-C of pentose sugar by an ester bond. One polynucleotide chain is formed when the phosphate of one nucleotide forms a phosphodiester bond with the sugar of another nucleotide.
A double-stranded structure is formed by base pairing between nucleotides. The adenine binds to thymine by two hydrogen bonds and guanine binds to cytosine by three hydrogen bonds.
Therefore the molecules of DNA are composed of long chains of nucleotides.

What are the locations and end products for the processes of transcription and
translation?
Answer: The transcription is the process of production of mRNA molecules from each separate strand of DNA individually and the translation is the production of protein by using the genetic information present in the mRNA.
Explanation:
The process of transcription occurs inside the nucleus of the cell in the eukaryotic cell typically not in prokaryotic cell whereas the translation process occurs in the cytoplasm with the help of ribosome.
mRNA is the product of transcription whereas the polypeptide chain of amino acids is the production of the translation in which further forms the protein.

What does it mean that earlobe attachment is a continuous trait?
Answer:
If you decided that the continuous spectrum of earlobe shape was a more accurate way to describe the variation, you aren’t alone. Family and genetic studies show that earlobe attachment is actually not a simple trait, but rather a complex trait, affected by multiple genes and environmental factors.

What type of energy has to do with a change in temperature?
Answer: changes in heat energy change temperature
Explanation: heat energy can be thought of as energy in individual atoms or molecules, which vibrate more as energy increases. Temperature is a measure of heat energy. For example, many substances expand as heat energy causes it atoms/molecules to vibrate more and occupy more space. We can use this property to measure energy as temperature by using the expansion of a liquid as in thermonmeters.

What absorbs water in the digestive system
Your answer is Small Intestine.
Your small intestine makes digestive juice, which mixes with bile and pancreatic juice to complete the breakdown of proteins, carbohydrates, and fats. Bacteria in your small intestine make some of the enzymes you need to digest carbohydrates. Your small intestine moves water from your bloodstream into your GI tract to help break down food. Your small intestine also absorbs water with other nutrients.
Answer: Small intestine
Either you put small intestine in the wrong place, or you're able to put the same one for multiple questions

A stone 'X' of mass 2 kg is at the height of 2 m from the ground level
Another similar stone 'Y' of mass 4 kg is at the height of 4 m from the ground
level. What is the difference between their potential energy?
un minutes Calculate
Answer:
120 joule.
Explanation:
Given
For the stone X
Mass (m) = 2 kg
Height (h) = 2 m
Acceleration due to gravity (g) = 10 m/s²
Then we have the formula to calculate the potential energy
P.E 1 = mgh
= 2 * 10*2
= 40 joule
Now for Stone Y
mass (m) = 4 kg
height (h) = 4 m
acceleration due to gravity (g) = 10 m/s²
Now
P. E2 = mgh
= 4 * 10* 4
= 160 joule
Now the difference between their potential energy is
= P. E2 - P. E 1
= 160-40
= 120 joule
Hope it will help you :)
