7. Which of the following processes DOES NOT produce new genetic combinations?
crossing over during meiosis
b. fertilization in sexually-reproducing organisms
c. independent assortment in gamete production
d. replication of DNA in mitosis
Replication of DNA in mitosis does not produce new genetic combinations. The correct option is d.
In mitosis, DNA replication does not result in novel genetic combinations. Somatic cells go through a process called mitosis, which produces two identical daughter cells with the same genetic makeup as the parent cell.
The DNA is properly duplicated during mitosis while keeping the same genetic sequence. Therefore, during this procedure, no new genetic combinations or variants are introduced.
The other processes, including crossing over during meiosis, fertilisation in sexually reproducing organisms, and independent assortment in gamete formation, all help to produce novel genetic combinations by recombining genetic material.
Thus, the correct option is d.

Meiosis and mitosis have different stages that share some similarities and differences. What
distinguishes Prophase during mitosis from Prophase I during meiosis?
Group of answer choices
During meiosis Prophase I, crossing over occurs which increases genetic diversity.
During meiosis Prophase I, chromatin condenses and shortens.
During mitosis Prophase, spindle fibers pull the sister chromatids apart.
During mitosis Prophase, chromatin moves to the central plane of the cell.

What is the role of mutations in creating variation in bird beak types?
Answer:
In order for a bird's beak to evolve into different a types, a mutation must occur first.
Explanation:
All evolution relies on mutations or changes to the DNA. Bird beaks adapt to the environment to be better suited to obtain food. A bird that used to have a pointy beak for stabbing bugs might move to an area with an abundance of seeds. Their DNA mutates so that their offspring can have short beaks to pick up seeds.

Summary of the cell membrane structure.
Answer: The plasma membrane is composed of a bilayer of phospholipids, with their hydrophobic, fatty acid tails in contact with each other. The landscape of the membrane is studded with proteins, some of which span the membrane. Some of these proteins serve to transport materials into or out of the cell. The principal components of the plasma membrane are lipids (phospholipids and cholesterol), proteins, and carbohydrate groups that are attached to some of the lipids and proteins. A phospholipid is a lipid made of glycerol, two fatty acid tails, and a phosphate-linked head group.

Which carbon compounds are formed over the course of the Calvin cycle? In what form of sugar to cells
store carbohydrates? (Hint: it is a product made AFTER the calvin cycle)
Answer:
The molecules of ADP and NAD+, resulting from the reduction reaction, return to the light-dependent reactions to be re-energized. One of the G3P molecules leaves the Calvin cycle to contribute to the formation of the carbohydrate molecule, which is commonly glucose (C6H12O6).
Explanation:
In the course of Calvin cycle, carbon dioxide molecules (CO₂) are combined with each other and with the electrons and protons from NADPH to form glucose (C₆H₁₂O₆). The glucose formed is stored in the form of starch.
What is Calvin cycle?Calvin cycle is a series of chemical reactions which convert carbon dioxide and hydrogen-carrier compounds into glucose. The carbon atoms used to build carbohydrate (glucose) molecules comes from carbon dioxide gas which is exhaled by animals.
The molecules of ADP and NAD⁺, resulting from the reduction reaction of Calvin cycle, returns to the light-dependent reaction to be re-energized. One of the G-3-P molecules leave Calvin cycle to contribute to the formation of the glucose molecule (C₆H₁₂O₆). This carbohydrate is stored in plants in the form of starch.

Explanation:
Describe the modern model of the atom. Your discussion should include: the three main types of particles that make up an atom; the charge and location of each particle; and explain what the overall charge of the atom is. *
Answer:
See the answer below
Explanation:
The modern model of the atom sees it as a small structure with a dense, positively charged core called nucleus. The nucleus houses most of the masses of the atom and consists of the proton and the neutron. The positively charged proton is primarily responsible for the positiveness of the nucleus. At some distance away from the nucleus is a light, negatively charged particle called the electron that revolves around the nucleus in an orbit-like fashion .
For a neutral atom, the number of the positively charged proton balances that of the negatively charged electron which circulate rounds the nucleus. Atoms in which these two particles do not balance each other are no longer described as being neutral.
How does the process of gel electrophoresis produce DNA fingerprints? An electric current sorts DNA nucleotides according to their bases. O An electric current cuts a DNA strand into segments of various lengths O An electric current causes segments of DNA to move at different rates O An electric current supplies a charge to uncharged segments of DNA
Answer:
Gel electrophoresis
Explanation:
Gel electrophoresis is a technique used to separate DNA fragments according to their size. DNA samples are loaded into wells (indentations) at one end of a gel, and an electric current is applied to pull them through the gel. DNA fragments are negatively charged, so they move towards the positive electrode.
What kind of pattern do you notice with the structure of DNA
Answer:
One pattern is that the A binds with T ans C with G for the DNA. The DNA transcription starts with the binding of the enzyme RNA polymerase to the promoter. The RNA then begins transcribing in data using one strand of DNA as the template. Thymine is replaced with uracil. To cleave the strand, the bacteria can use a termination step.

What is the correct order to make a protein?
Answer:
The correct sequence of events in protein synthesis is transcription, then translation.
The correct order to make a protein is DNA >> RNA >> protein.
During gene transcription, a specific fragment of DNA (i.e., a gene) is used as a template to create a complementary RNA molecule known as a messenger RNA molecule.
Subsequently, this messenger RNA is then used as a template to create a polypeptide chain (i.e., a protein) in the ribosomes by a process called translation.
In conclusion, the correct order to make a protein is DNA >> RNA >> protein.

Describe the function of the following
organelles:
a. Nucleus-
b. Cell membrane-
c. Chloroplasts-
d. Cell Wall-
e. Cytoplasm-
Answer:
Explanation:
The nucleus is the part of the cell that controls all other functions of the cell and the organelles. It also contains DNA.
The cell membrane acts as a semipermeable barrier between the cell and the outside environment to facilitate active and passive diffusion, and to maintain the concentration of solutes inside the cytoplasm. It also has receptors on its outer surface to communicate with other cells.
Chloroplasts use energy from photons of light from the sun to undergo photosynthesis, which helps the cells create glucose, or in other words, make its own food (in plants).
The cell wall protects plant cells from antigens and, due to its boxy shape, also helps the plant have a more rigid structure so that plants can stand upright.
The cytoplasm of a cell is the fluid within the cell membrane through which organelles in the cell move around. It is also the location where glycolysis typically takes place. The cytoplasm is mostly water with salts dissolved into it.

7. Which represents
an indirect economic value of
biodiversity?
A. food
B. clothing
C. flood protection
The answer is C. Flood Protection. Biodiversity provides numerous economic benefits, and one of the most important is flood protection.
What is the role of biodiversity ?Biodiversity helps to reduce the risk of flooding by providing natural barriers such as trees and vegetation that can absorb and store water, helping to reduce the amount of water that flows into rivers and streams.
Biodiversity also helps to reduce erosion by stabilizing the soil, which can help to prevent flooding by reducing the amount of sediment that can be washed away.
Additionally, biodiversity can help to reduce the impact of floods by providing habitats for wildlife that can help to reduce the impact of flooding on human communities.
For example, certain species of birds can help to reduce the impact of flooding by eating the insects that can spread water-borne diseases.
Biodiversity also helps to reduce the impact of flooding by providing habitats for aquatic species that can help to reduce the amount of damage caused by floods. All of these benefits help to make biodiversity an important indirect economic value.
