B. During carbon fixation
C. Immediately after reduction
D. Immediately after regeneration
The answer is C. The Calvin cycle occurs in the stroma o the chloroplast in a plant cell. It involves the dark stage where carbon dioxide is reduced by protons created in photolysis from the light stage of photosynthesis. The 3-phosphoglyceric acid (3-PGA) is phosphorylated by ATP and then immediately reduced by NADPH in the reduction step. After reduction, G3P is formed and exits the cycle. Other G3Ps are regenerated into a ribulose-1,5-bisphosphate (RuBP) acceptor molecule for the cycle to continue.
the answer is c i just did it
Answer:
Water dirt and sunlight and also soil and rocks
Explanation:
black fur
Himalayan Rabbit
A scientist shaved an area of white fur on the back of a Himalayan rabbit and placed an ice
pack over the shaved area. The shaved area grew black fur.
Which of these best explains why the hair that grew back where the ice pack was placed was
black and not white?
F The genes for black hair were activated by specific temperatures.
G The white hair mutated to black hair as the rabbit's body temperature decreased.
H The coat color changed from white to black with the age of the rabbit.
3 White hair only grows during certain times of the year.
Rabbits regulate their body temperature by using their ears. A fever or a dip in body temperature could be indicated by extremely chilly or hot ears. Thus, option F is correct.
In general, rabbits thrive in cooler climates. In the fall, rabbits stop shedding their fur and develop a thick coat of fur that keeps them warm in the winter. Low temperatures of 32 degrees don't really bother them.
Strong back legs offer rabbits the speed they need to run away from predators. Their feet have fur on the bottoms for warmth and strong claws for traction.
The white hair only grows in cold temperatures. Just because they put an ice pack on the rabbit does not mean that it's cold.
Therefore, The genes for black hair were activated by specific temperatures

Answer: The clavicle
Explanation: The clavicle is a long, slender bone that connects the shoulder to the breastbone, is commonly referred to as the collarbone and is often visible just beneath the skin.
The bone known as a collarbone is called the clavicle. It articulates with the manubrium of the sternum medially and the acromion of the scapula laterally.
The bone known as a collarbone is called the clavicle. It is an elongated bone that articulates with the manubrium of the sternum medially and the acromion of the scapula laterally. The clavicle has three regions: the medial end, the lateral end, and the shaft. It forms the sternoclavicular joint with the manubrium of the sternum and articulates with the acromion of the scapula. Despite its vital function, the clavicle is one of the most commonly fractured bones in the body. This is often due to its positioning and the amount of force exerted upon it during activities such as a fall whilst arms are outstretched. Despite potential incidents, the surpassing structure of the clavicle helps keep the underlying blood vessels and nerves intact during fractures.

a. DNA
b. glucose
c. protein
d. lipid
Answer: C. Protein
Explanation:
Enzymes are a type or form of proteins as they are also made up of amino acids, which are the building blocks of proteins. These amino acids will dictate how it will function.
Enzymes function to speed up chemical reactions within cells.
DNA is translated to produce tRNA, which assembles proteins.
DNA directs the production of mRNA; mRNA is translated to make tRNA; tRNA assembles the protein.
RNA directs the production of DNA; DNA contains genes that produce tRNA, which builds the protein.
The most probable answer here is the third option from the top, but it not entirely accurate because mRNA is not translated to make tRNA. The latter is already present in the cytoplasm of the cell.
The first step in protein synthesis is Transcription in which a new RNA molecule is synthesized from a DNA template. This process takes place in the nucleus of the cell. The new RNA strand is called messenger RNA or simply mRNA because it carries information from the DNA in the nucleus to the site where this information can be Translated from nucleotide language to amino acid language. This site is actually the ribosome/s usually located in the cell cytoplasm.
The ribosome attaches to the mRNA and begins to read the code on the mRNA.
tRNA which is free in the cytoplasm or attached to the ribosome begins to fetch the correct amino acid coded for by the mRNA from the amino acid pool in the cytoplasm.
These amino acids are linked together in the ribosome with the help of enzymes to make a polypeptide chain which is actually the protein, newly formed.
The statement that is true about Protein synthesis is that DNA directs the production of mRNA; mRNA is translated to make tRNA; tRNA assembles the protein.
The correct statement about protein synthesis is: DNA directs the production of mRNA; mRNA is translated to make tRNA; tRNA assembles the protein.
Protein synthesis involves two main steps: transcription and translation. Transcription occurs in the nucleus and involves the synthesis of mRNA using a DNA template.
The mRNA molecule then moves to the cytoplasm where it is translated by ribosomes and tRNA molecules.
The tRNA molecules bring specific amino acids to the ribosome, which then assembles them into a polypeptide chain to form a protein.
Overall, DNA provides the instructions for the synthesis of mRNA, and mRNA serves as the template for protein synthesis.
