Answer:
A
Explanation:
the northern hemisphere is the opposite from the southern hemisphere
Since northern and southern hemisphere are in opposite directions therefore, option (A) is correct.
Why are the seasons reversed in each hemisphere?The axis of rotation of the Earth is inclined with regard to the plane in which it orbits the sun. This is the root reason of the changing of the seasons. When the axis of the earth is aligned with the sun, summer arrives in that hemisphere of the planet. Expect winter to arrive when the axis of the earth is tilted away from the sun.
Different places of Earth receive the Sun's most direct rays throughout the year. When the North Pole tilts toward the Sun, it's summer in the Northern Hemisphere. When the South Pole tilts toward the Sun, the Northern Hemisphere experiences winter.

Which of the following processes cycles matter through different parts of an ecosystem?
More than one answer may be correct.
1. the nitrogen cycle
2. the water cycle
3. the carbon cycle
Answer:
the nitrogen cycle, the water cycle, and the carbon cycle
Explanation:
The water, carbon, and nitrogen cycles move nutrients through the different parts of an ecosystem. Water moves through organisms and the environment in different phases. Carbon moves through an ecosystem in carbon dioxide, minerals, and organic compounds. Nitrogen moves through an ecosystem in nitrogen gas, ammonium, nitrates, and organic compounds.
The biogeochemical cycle is a pathway that circulates the chemicals through the abiotic and the biotic factor. The nitrogen, water, and carbon cycle through various regions of an ecosystem.
What is a biogeochemical cycle?The biogeochemical cycle is the movement of the chemicals and compounds of carbon, nitrogen, and water in the biosphere (biotic) and the atmosphere, lithosphere, and hydrosphere (abiotic) spheres of the earth.
These cycles move the nutrient through different spheres in the form of inorganic and organic compounds. It is an essential part of the ecosystem as they regulate the flow of the natural elements.
Therefore, option 1. nitrogen cycle, option 2. water cycle, and option 3. carbon cycle move through various parts of an ecosystem.

Once assembled, what is the key to a protein's unique function?
Answer:
Once assembled, what is the key to a protein's unique function? The manner in which proteins fold is the key to their function
The endoplasmic reticulum is an important region where protein folding occur. Because proteins need to be appropriately folded into distinct structures, this is an essential biological function.
What is importance of protein folding?Proteins that are misfolded or are unfolded improperly impart to the pathophysiology of many illnesses.
Protein folding is a highly delicate process that is regulated by a variety of external stimuli, such as temperature, pH, chemicals, molecule crowding, electric and magnetic fields, and temperature.
These elements affect a protein's capacity to fold into the appropriate functional forms.
Therefore, Protein folding give unique properties to protein functions.

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 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.
