It can proceed in the dark.
The answer above me is wrong. The correct answer is D: It can proceed in the dark.
Calvin cycle is considered a dark reaction because it can proceed in the dark. Details about Calvin cycle can be found below.
What is Calvin cycle?Calvin cycle is the second stage of photosynthesis after light dependent reaction where sugars are produced.
The Calvin cycle is a series of biochemical reactions that take place in the stroma of chloroplasts in photosynthetic organisms.
Calvin cycle is also called light independent reactions because it can occur in the dark or absence of light.

The adaptation that allows some of these animals to run fast would be an example of natural selection if it helps them
Answer:
a chaeta runs fast to catch its pray Please Mark Me Brainliest
Explanation:
The adaptation that allows some of these animals to run fast would be an example of natural selection if it helps them hunting animals that ran faster than them and need for survival.
What is the difference between adaptation and natural selection?The action of natural selection consists of selecting individuals more adapted to a given ecological condition, eliminating those disadvantageous for that same condition. The most adapted expression refers to the greater probability that a given individual will survive and leave offspring in a given environment.
Natural selection occurs due to the need for survival and adaptation of species to the environment. It is through it that the most adapted species persist in the environment.

explain how sexual reproduction increases genetic diversion in many species of plants and animal, making sure to include the importance and function of gamites
Answer:
Sexual reproduction increases genetic diversion because there are two parents, unlike in asexual reproduction where there is only one.
Explanation:
During sexual reproduction, gamites come from both parents and mix together to create genes and traits for the offspring. Gamites are formed through meiosis (reduction division), in which a germ cell undergoes two fissions, resulting in the production of four gametes.
Which of the following is not a name for a chain of amino acids?
A. Polypeptide
B. Polyamino
C. Polymer
D. Protein
Polyamino is not a name for a chain of amino acids.
what are amino acids?
An amino acid is a fundamental molecule that serves as the building block for proteins. There are 20 different amino acids. A protein consists of one or more chains of amino acids (called polypeptides) whose sequence is encoded in a gene. Some amino acids can be synthesized in the body, but others (essential amino acids) cannot and must be obtained from a person’s diet.
therefore option B is the correct answer.

Genes are sections of DNA that code for a particular trait. Genes are...
A. Carbohydrates
B. Lipids
C. Proteins
D. Nucleic Acids
Answer:
D. Nucleic acids
Explanation:
Answer:
C. Proteins.
Explanation:
A gene is the basic physical and functional unit of heredity. Genes are made up of DNA. Some genes act as instructions to make molecules called proteins. However, many genes do not code for proteins.URGENT: you are studying a small animal that lives in an environment that experiences frequent and severe drought. which of the following reproductive strategies would this animal likely exhibit?
a. many offspring, low parental involvement, early maturation
b. few offspring, low parental involvement, early maturation
c. few offspring, high parental involvement, late maturation
d. many offspring, high parental involvement, late maturation
Answer:
many offspring, low parental involvement, early maturation
Explanation:
if the mother doesn't have to stay with the offspring, then she wouldn't need to share food and water with her offspring during a drought, which would decrease her and her offspring's chances of survival. if the mother has many offspring at once, they are more likely to have just a few of them to survive.

__________________________________________________________
Q2: What are the parts of an electromagnet?
A2: According to Sciencing, Significance. Electromagnets are a vital part of everyday life.
Operation. Electromagnets behave the same way as regular magnets.
Construction. The basic components of an electromagnet are a wire and a power source.
Special Types of Electromagnets. Solenoids are electromagnets that are in the form of a helix.
__________________________________________________________
Q3: How is an electromagnet useful when compared to a permanent magnet?
A3: According to Toppr, The main advantage of an electromagnet over a permanent magnet is that we can quickly change the magnetic field by controlling the amount of electric current in the winding. The magnetic field created by an electromagnet is proportional to both the number of turns in the winding and the current in the wire.
