answer: sexual reproduction
explanation:
mitosis is when a cell divides to create two exact same "daughter cells" - mitosis is needed for the accumulation of more cells, wound repair, cloning, and asexual reproduction
meiosis is when a cell divides to form gametes (egg or sperm) - meiosis is needed for sexual reproduction
Answer:
The correct answer is - sexual reproduction.
Explanation:
Mitosis is one of the cell cycle mechanisms that take place in the somatic cell and produce identical daughter cells by one parent cell. These daughter cells have the exact number of the chromosome as the parent cell. The main goal of mitosis is growth and replace the dead or worn-out cells.
It also helps in reproduction in various plant or animal cells through asexual reproduction or cloning, or binary fission, however, the process and mechanism are similar. In sexual reproduction mitosis type of cell cycle takes place in sex cells to produce gametes with half number of chromosome.

Which one of the organic molecules listed below has more energy stored in its bonds. Proteins Carbohydrates Lipids Nucleic Acids
Answers
Answer:
Lipids
Explanation:
Out of the four biological molecules in living systems (carbohydrate, lipids, proteins, nucleic acids), Carbohydrates and lipids have the ability to store energy in their chemical bonds. However, lipids/fats are primarily used by cells for long term storage of energy due to their ability to store more energy than any other organic biomolecule.
The high energy storing ability of lipids is attributed to the carbon bonds in their long fatty acid chain. They store energy in the covalent bonds that form between this carbon elements. The breaking down of one gram of a lipid yields 9 calories of energy, which is more than the 4 calories yielded by proteins and carbohydrates respectively

Answers
Cytosine, a nitrogenous base found in DNA and RNA, pairs with guanine. The correct answer is option B.
This pairing is based on the complementary base pairing rule in which cytosine forms three hydrogen bonds with guanine. The other base pairs in DNA are adenine with thymine, and in RNA, adenine pairs with uracil. The complementary base pairing is crucial for DNA replication and transcription processes. Cytosine and guanine, along with adenine and thymine/uracil, form the base pairs that make up the rungs of the DNA double helix structure.Understanding base pairing is fundamental to understanding the structure and function of nucleic acids.

. If untreated, how will HIV’s effect on helper T-Cells affect a person’s immune response? Be specific using details from what you have learned.
Answers
If left untreated, HIV can significantly affect a person's immune response in several ways. Firstly, HIV can reduce the number of CD4+ T cells in the body, leading to a weakened immune system. As the virus replicates and destroys more CD4+ T cells, the body becomes increasingly vulnerable to opportunistic infections and cancers.
Secondly, HIV can impair the function of CD4+ T cells that remain in the body. Even if there are enough CD4+ T cells present in the body, they may not function correctly due to HIV's impact on their signaling pathways. This can lead to a weakened immune response and an increased risk of infections.
Answer:
HIV attacks a specific type of immune system cell in the body. It's known as the CD4 helper cell or T cell. When HIV destroys this cell, it becomes harder for the body to fight off other infections. When HIV is left untreated, even a minor infection such as a cold can be much more severe.

If a man with blood type AB marries a woman who is heterozygous for blood type B, what is the probability of having a child with blood type O?
Answers
Considering the probabilities of these outcomes, the chance of having a child with blood type O is 50% if a man with blood type AB marries a woman who is heterozygous for blood type B.
To determine the probability of having a child with blood type O, we need to analyze the possible blood type combinations that can result from the parents' genotypes.
The man has blood type AB, which means he has both A and B antigens on his red blood cells. The woman is heterozygous for blood type B, meaning she carries one B allele and one recessive O allele. The possible genotypes for the man are AB (IAIB) and the possible genotypes for the woman are BB (IBIB) or BO (IBi).
When these two individuals have offspring, their children can inherit any combination of the parents' alleles. The possible combinations are as follows:
AB x BB: All children will have blood type B (IBIB), as both parents only carry the B allele.AB x BO: There is a 50% chance that each child will inherit the O allele from the mother, resulting in blood type O (ii). There is also a 50% chance that each child will inherit the B allele from the mother, resulting in blood type B (IBi).

Compare and contrast a fossil with a trace fossil
Answers
Definition:
- Fossil: A fossil refers to the preserved remains or traces of organisms that lived in the past. It can include the hard parts of plants or animals, such as bones, shells, teeth, or wood.
- Trace Fossil: A trace fossil, also known as an ichnofossil, refers to indirect evidence of prehistoric life activities, such as footprints, burrows, tracks, trails, or even feces (coprolites).
Formation:
- Fossil: Fossils form when the remains or hard parts of organisms are buried in sediment or other materials, undergo mineralization over time, and become preserved.
- Trace Fossil: Trace fossils form when an organism's activity or behavior, rather than the organism itself, creates an impression or trace that is preserved in the geological record.
Information Provided:
- Fossil: Fossils can provide direct information about the physical characteristics, anatomy, and structure of ancient organisms. They can offer insights into their evolutionary relationships, adaptations, and paleoenvironments.
- Trace Fossil: Trace fossils provide indirect information about the behavior, locomotion, feeding habits, and ecological interactions of ancient organisms. They can reveal details about their movement patterns, burrowing behavior, or group activities.
Preservation:
- Fossil: Fossils typically require specific conditions for preservation, such as rapid burial, anoxic environments, or mineral-rich sediment. They are often preserved in sedimentary rocks, amber, or ice.
- Trace Fossil: Trace fossils can form in various types of sediments, including mud, sand, or volcanic ash. They can also occur in hardened substrates like limestone or volcanic rock.
Types and Examples:
- Fossil: Examples of fossils include bones, teeth, shells, petrified wood, and preserved soft tissues like feathers or leaves.
- Trace Fossil: Examples of trace fossils include footprints, tracks, burrows, nests, feeding traces, or coprolites (fossilized feces).
In summary, a fossil refers to the preserved remains or traces of organisms themselves, providing direct information about their physical characteristics. On the other hand, a trace fossil refers to indirect evidence of prehistoric life activities, offering insights into behaviors, locomotion, and ecological interactions. Both types of fossils contribute to our understanding of ancient life forms and ecosystems, but through different perspectives and types of evidence.

how long does it take a 180g sample of radioactive gold (half-life=2.69) to decay to 1/8 its original mass?
Answers
It would take approximately 6.27 years for a 180g sample of radioactive gold (with a half-life of 2.69 years) to decay to 1/8 its original mass.
The decay of radioactive gold can be modeled by the equation:
N(t) = N₀ * (1/2)^(t / t₁/₂)
where N(t) is the remaining mass at time t, N₀ is the initial mass, t₁/₂ is the half-life, and t is the elapsed time.
In this case, we want to find the time it takes for a 180g sample of radioactive gold to decay to 1/8 its original mass. This means that the remaining mass (N(t)) is 180g / 8 = 22.5g. We can substitute these values into the equation and solve for t:
22.5g = 180g * (1/2)^(t / 2.69)
Dividing both sides by 180g:
(22.5g / 180g) = (1/2)^(t / 2.69)
Taking the natural logarithm of both sides:
ln(22.5/180) = (t / 2.69) * ln(1/2)
Simplifying:
t = (2.69 / ln(1/2)) * ln(22.5/180)
t ≈ 6.27 years
Therefore, it would take approximately 6.27 years for a 180g sample of radioactive gold (with a half-life of 2.69 years) to decay to 1/8 its original mass.
