Answer:
b.cell from a sunflower leaf
The structure that can have chloroplast is the cell from sunflower leaf. The correct option is B.
What is chloroplast?Chloroplasts are chlorophyll-containing organelles found in plant cells; they are necessary for Earth life because photosynthesis occurs in chloroplasts.
Proplastids give rise to chloroplasts, as do chromoplasts, leucoplasts, as well as other plastids.
Chloroplasts are plant cell organelles that use photosynthetic energy to convert light energy into reasonably stable chemical energy.
They survive life on Earth by doing so. Chloroplasts also perform a variety of metabolic functions for plant cells, such as the generation of fatty acids and membrane lipids.
Chloroplasts are found in all green plants and algae. Chloroplasts can also be found in photosynthesis that don't appear green, such as giant kelp's brown blades or certain plants' red leaves.
Thus, the correct option is B.

Which student will most likely overcome their nerves?
A.one who thinks positively and practices the speech in advance
B.one who thinks positively and stays up late to practice the speech
C.one who gets plenty of rest and eats sugary foods for energy
D.one who gets plenty of rest and avoids practicing the speech
Answer:
A.one who thinks positively and practices the speech in advance
Explanation:
It makes more sense
Student will overcome their nerves who thinks positively and practices the speech in advance
Positive behaviourThe person who thinks positively and practices the speech in advance will most likely overcome their nerves because the positive behaviour has good effect on the personality of an individual. Those people who think negative, they will not get success in their life.
Practice's benefitsThere is a saying that practice makes a man perfect. That person who regularly practice a specific topic, they can do the speech very well or other things in their life so we can conclude that student will overcome their nerves who thinks positively and practices the speech in advance.

Which biomolecule provides the instructions to build enzymes?
A. Carbohydrates
B. Lipids
C. Nucleic acids
D. Proteins
Proteins are the building blocks of enzymes, and proteins are made up of amino acids that are linked together in one or more polypeptide chains. Therefore, option (D) is correct.
What are enzymes?Enzymes are proteins that aid in the acceleration of metabolic processes, also known as the chemical reactions that take place in our bodies. They are responsible for the creation of some chemicals while also decomposing others. Enzymes are present in everything that is alive. Enzymes are something that are produced by our bodies spontaneously.
Enzymes regulate most biochemical reactions in animals, plants, and microbes, thus there are many examples. Animal digestive enzymes are well-known. Gastric juices break down food with the enzyme pepsin. Salivary amylase turns starch into sugar, starting digestion.

Patients generally report conscious awareness of posthypnotic suggestions. Please select the best answer from the choices provided T F
Answer:
false
Explanation:
edge 2020
Conscious awareness of posthypnotic suggestions is a false statement because it creates a subconscious.
What are posthypnotic suggestions?The directive was given to the subject during a hypnotic trance that must be carried out once the subject awakens.
A post-hypnotic suggestion is essentially a specific directive to be followed after the hypnotherapy session to the subconscious.
An illustration of this would be going to a hypnotist for help with weight reduction and having the suggestion made that every time you feel like a sweet sort of meal, you will feel like drinking some water instead" ingrained in your subconscious.
Therefore posthypnotic suggestions of having conscious awareness are false statements.

Why is meiosis important in maintaining genetic diversity?
Question 6 options:
A Meiosis creates diversity by cutting each chromosome exactly in half.
B The two different chromosomes of the organism producing the sex cell (egg or sperm) are mixed up during crossover, creating a new combination of alleles.
C It creates sex cells (eggs or sperm) that have exactly the same alleles (version of a gene) as the parents.
D The chromosomes in meiosis are copied so they are exactly the same as the organism producing the gamete, except they have just one copy.
Answer:
We now know that meiosis is the process of chromosomal reduction which allows the production of haploid germ cells necessary for sexual reproduction. Meiosis is furthermore important for its role in enabling genetic diversity and facilitating the repair of genetic defects through recombination.
Explanation:
Brainliest please?
Meiosis is a specialized form of a cell division in which number of chromosomes is reduced to half. The reduction in chromosome number is achieved by one round of DNA replication and two rounds of chromosome segregation.
Meiosis produces genetic variation by the process of recombination.Recombination occurs when two molecules of DNA exchange pieces of their genetic material. The process of recombination occurs during the prophase stage of meiosis I. In meiosis, crossing over occurs between the non-sister chromatids in a homologous pair (one from each parent) of chromosomes.The correct answer is option B. The two different chromosomes of the organism producing the sex cell (egg or sperm) are mixed up during crossover, creating a new combination of alleles.
Other options-
A. Meiosis creates diversity by cutting each chromosome exactly in half - incorrect .In meiosis the chromosome number is reduced to half.
C. It creates sex cells (egg or sperm) that have exactly the same alleles (version of a gene) as the parents-incorrect. The sex cells produced are not genetically identical to the parent cell.
D. The chromosome in meiosis are copied so they are exactly the same as the organism producing the gamete, except they have just one copy-incorrect. In meiosis the chromosomes are not exactly copied.

Identify the control group for the rat experiments described in the Paralytic Shellfish Poisoning Scenario.
Answer:
This question is incomplete
Explanation:
This question is incomplete. However, the control group of an experiment is the group in which every other group of the experiment is firstly compared with. This is because control groups are usually not administered with any form of treatment. Thus, the control group of the experiment/scenario referred to in the question will be the group that did not receive any form of treatment and was probably given water or placebo.

When a bee visits a flower for sweet, sweet nectar, the plant's gametes are also spread to anoher plant. What kind of symbiotic relationship is this?
Answer:
Mutualism
Explanation:
Mutualism is a type of symbiotic relationship in which the two species of organisms involved benefit from one another i.e. the actions of one benefits the other.
In this question, a bee is said to visit a flower for sweet nectar, however, in the process of feeding on the flowers nectar, the plant's gametes are also spread to another plant by the bee. This is a type of MUTUALISTIC RELATIONSHIP because the plant is beneficial to the bee by providing food (nectar) while the bee also helps the plant by helping it pollinate.

9. What type of bond is pictured in the image below?
a. covalent bond
b. ionic bond
c. metallic bond
d. electron bond
ONLY 9
Answer:
c. metallic bond
Explanation:
Metallic bonding, unlike other forms of atomic bonding, involves delocalized elections. The negatively charged electrons form a "sea" around metal cations. Electrons within the valence shells of metals are only held loosely within their molecular orbits- the metals are held together due to the strong attraction between these delocalized electrons and positive nuclei.
The electrons are typically described as mobile, free, and delocalized. These traits are responsible for several metallic properties such as:
