Answer:
Crossing over, independent assortment, and random fertilization all result in genetically diverse offspring.
During meiosis, which is split into 2 categories (Oocyte meiosis and spermatogenesis), a gamete undergoes a process like mitosis, however it occurs twice. A gamete starts out with twice as many chromosomes as a normal cell (It's a diploid), and before prophase I and metaphase I, crossing over occurs, "mixing up" genetic material. This adds diversity.
Independent assortment means that when a cell receives one allele, it does not influence the chances of getting another allele.
Example, in pea plants, if a cell were to receive a green(G) allele, there's still a 50/50 chance of it receiving either a green(G) allele, or a yellow(Y) allele.
Random fertilization increases the diversity even more. Females can produce a large amount of ova in their lifetime. After mating, the fact that the ova can have any combination of genetic material, and that there's over 40 million potential spermatozoa with different genetic material that could combine with it increases diversity.

No, a red(RR) and pink(Rw) flower could not create a white(ww) flower. White is recessive, meaning 2 forms of the allele are needed for it to show. As red(RR) has no white(ww) alleles, there would be more pink(Rw) flowers. Two pinks(Rw), a pink(Rw) and white(ww), or two whites(ww) could create more white flowers though.

Know the difference between replication and repetition
Answers
Answer:
Repetition is when a scientist does the same experiment a number of times; replication is when other scientists reproduce a scientist’s experiment. Repetition is when a scientist publishes in more than one scientific periodical; replication is when another scientist reproduces another scientist’s results.
Explanation:
Answer:
Repetition refers to performing multiple trials throughout an experiment. Repetition reduces mistakes and increases one’s confidence in the results. Replication refers to the ability of a process to be repeated by another individual. When one scientist replicates the experiment of another, the experiment should produce the same results.

The choice that is involved in both sexual and asexual reproduction is the spores that are in the third option, as the others are involved in sexual reproduction, such as the sperm, egg, etc.
What is the advantage of sexual reproduction over asexual reproduction?Both types of reproduction have advantages, for example, if a mutation occurs and becomes genetic, the chance of getting the disease is lower in sexual reproduction than in asexual reproduction. The possibility of recombination and crossing over reduces the rate of genetic disorders in sexual reproduction, whereas in asexual reproduction, the mutation passes from one to the other.
Hence, the choice that is involved in both sexual and asexual reproduction is the spores that are in the third option, as the others are involved in sexual reproduction, such as the sperm, egg, etc.

Answers
The piece of evidence that Alfred Wegener's original theory of continental drift has access to is the mountains in North America appearing to match up with mountains in Northern Europe. Thus, the correct option for this question is D.
What is Continental drift?Continental drift may be defined as a type of hypothesis that represents a gradual movement of the Earth's continents over geologic time relative to each other. This movement of the Earth's continents results from the motion of tectonic plates.
According to Alfred Wegener's original theory of continental drift, the continents of the Earth have been adjoined together and have migrated away from each other at different times in the history of the Earth.
This reflects that mountains in the continent of North America appear to match up with the mountains in the continent of Northern Europe.
Therefore, the correct option for this question is D.

Climate change is the website which most likely provides reliable information about climate change. Thus, the correct option is C.
What is Climate change?Climate change refers to the long-term change in temperatures and weather patterns of the area. These changes in temperature may be natural, however since the 1800s, human activities have been the major driver of climate change, primarily due to the burning of fossil fuels like combustion of coal, oil, and gas, which produces heat-trapping gases that cause global warming.
The Intergovernmental Panel on Climate Change (IPCC) assesses the peer-reviewed literature on the climate change for every 5 to 6 years. Their assessment reports, which are also peer-reviewed, are a credible source of information for the climate change.

Answers
Answer:Plants have adaptations to help them survive (live and grow) in different areas. Adaptations are special features that allow a plant or animal to live in a particular place or habitat. These adaptations might make it very difficult for the plant to survive in a different place. This explains why certain plants are found in one area, but not in another. For example, you wouldn't see a cactus living in the Arctic. Nor would you see lots of really tall trees living in grasslands.
Explanation:
Answer:
These plants grow in very difficult environments. So, researching their genes may help botanists working in agricultural areas develop crops that can grow in inhospitable areas. Also, understanding how these plants survive in harsh conditions may help conservation scientists protect plants if their environments change.
