Which of the following accurately describes covalent bonds?
A. Covalent bonds are formed when atoms share one or more
electrons.
B. Covalent bonds are formed when atoms transfer one or more
protons.
C. Covalent bonds are formed when atoms share one or more
protons.
D. Covalent bonds are formed when atoms transfer one or more
electrons.
Answer:
A
Explanation:
A covalent bond consists of the mutual sharing of one or more pairs of electrons between two atoms. These electrons are simultaneously attracted by the two atomic nuclei. A covalent bond forms when the difference between the electronegativities of two atoms is too small for an electron transfer to occur to form ions.
Answer: The answer is A Covalent bonds are formed when atoms share one or more electrons
Explanation:
Gametes produced by the parents are shown along the __________________ and _______________ sides of the Punnett square.
Answer:
Vertical and horizontal
Explanation:
A punnet square is a tabular chart used in genetics to display the genotypic composition of the offsprings of two parents. To construct a punnet square, the alleles of the gametes produced by the parents is required.
The gametes produced by each parent via meiosis are placed along the vertical and horizontal sides of the punnet square. For example, if a cross occurs between two parents with the following genotype: AaBb and AAbb. The parents will produce the following gametes:
AaBb - AB, Ab, aB, ab
AAbb - Ab, Ab, Ab, Ab
These gametes produces by each parent will be placed along the sides (vertical and horizontal) of a punnet square to determine the genotype of the offsprings that will be produced.

what are the most common c0vId vaccine myths and how did they start? Explain your answer.
Answer:
The most common myths are:
- C0vid2019 vaccines cause autism
- C0vid2019 vaccines may modify your DNA
- C0vid2019 vaccines are unsafe
Explanation:
The most common myths associated with C0vid2019 vaccines are:
1- C0vid2019 vaccines may cause autism: In 1998, Andrew Wakefield and colleagues published a controversial study in the Lancet where they suggested that the measles, mumps, and rubella (MMR) vaccine may cause autism in some children. However, it has been showed that this study was based on erroneous statements and therefore this publication was retracted.
2- C0vid2019 vaccine may modify your DNA: it has been suggested that vaccines based on viral vectors (e.g. adenoviruses) and mRNA vaccines may modify the DNA of cells. This statement is false because these technologies cannot alter the DNA sequence. These vaccines are based on the production of an mRNA sequence that is translated into a viral protein (spike protein) which triggers an immune response
- C0vid2019 vaccines are unsafe: some people believe that C0vid2019 vaccines are unsafe because they were developed quickly. However, this statement is false because all vaccines (including C0vid2019 vaccines) need to follow rigorous safety standards to be approved by governmental agencies (i.e., they approved all clinical trials).

Explain how the cell division of cancer cells like these are misregulated. Identify genetic and other changes that might have caused these cells to escape normal cell cycle regulation
Answer:
Due to non-functioning of protein.
Explanation:
The cell division of cancer cells like these are misregulated because they can't be control by the proteins that is responsible for the control cell division. The cancer cells can multiply without any growth control factors, or growth-stimulating protein signals that control its growth. There are some proteins that is responsible for control of cell division but due to mutation that protein of substance stop working and the cancer cell grows uncontrollable.
A researcher stimulates, with a small electrical charge, a portion of a cat's limbic system. The cat suddenly jumps and acts as if it is fighting. What portion of the limbic system was stimulated
Answer: amygdala
Explanation:
The limbic system, refers to the set of brain structures that's located on the sides of the thalamus. The function of the limbic system include olfaction, behavior, emotion, and long-term memory.
Since the cat suddenly jumps and acts as if it is fighting, the portion of the limbic system that was stimulated is the amygdala.
Which statement best describes the starch content of two leaves taken from the same plant shown in the

leaf B
taken from plant in
bright light for 48 hours
(1) Neither leaf contains starch.
(2) Both leaves contain the same amount of starch.
(3) Leaf A contains more starch than leaf B.
(4) Leaf B contains more starch than leaf A.
The statement best describes the starch content of two leaves taken from the same plant shown in the chart is given: (4) Leaf B contains more starch than leaf A.
Dark reactionplants use carbon dioxide with ATP and NADPH from the light reactions to produce glucose.It takes place in the stroma of the chloroplast.Light reactionsThe energy is then temporarily transferred to two molecules, ATP and NADPHThe light reaction is important to produce ATP and NADPH which is used as fuel for starch production.Thus, The statement best describes the starch content of two leaves taken from the same plant shown in the chart is given: (4) Leaf B contains more starch than leaf A.

what is crop rotation
Answer:
MARK ME BRAINLIST
Explanation:
the practice of growing different crops in succession on the same land chiefly to preserve the productive capacity of the soil.
Answer:
Crop rotation was used during the agricultural revolution. It allowed the soil to be healthier and prevented the nutrients from being stripped from the soil. Crop rotation is when your land in separated into different fields for different plants. Usually you would have two or three. One field is left fallow (land that is taken care of, but does not have any crops), and the other one/s are for whatever you choose to plant. Each season you rotate your crops so each field has a turn to be fallow.
Explanation:
Example: you separate your land into three fields. Field 1 has potatoes, field 2 has wheat, and field 3 is fallow. Next season Field 1 is fallow, Field 2 has potatoes, and Field 3 has wheat.
