Answer:
Cellular Organization and Growth & Development
Explanation:
The fact that a human is initially defined by "a single cell" and later defined as "trillions of cells" demonstrates that all living things are made up of an organization of cells as cells are the building blocks of all life. The contrast of the single cell with the trillions shows the growth and development from the beginning of life to the fully developed form of an adult human.

(a) Komberg
(b) T.H. Morgan
(c) Gregor Mendel
(d) Reginald Punnett
Answer:
(d) Reginald Punnett
Explanation:
Reginald Punnett, an English geneticist, invented one of the simplest methods for calculating the mathematical probability of inheriting a specific trait. As a result, his method became known as a Punnett Square. It is the most basic graphical method for discovering all possible genotype combinations that may occur in offspring, which were named dihybrid cross and monohybrid cross.
I am joyous to assist you at any time.
Answer:
(d) Reginald Punnett
Explanation:
The representation of the genetic cross can be done by a tool known as Punnet square, which was back then proposed by Reginald Punnet. With this method, this scientist designed a way to measure how probable is a genotype frequency to occurs among the offspring.
So the answer to this question is (d) Reginald Punnet.

Would you predict that blooms are more commonly reported now than in the past, just as commonly reported, or reported less now? Explain
Answer:
It depends. Please look at the explanation.
Explanation:
Since the question does specify what the reference was, I will be referring to different time periods. This question is a bit complicated, and I apologize in advance that this answer will most likely be very long.
There are many things that affect how often these blooms are reported. For example, when people still lived in close colonies, they covered less water mass than now (also because of the population differences). However back then, there probably wasn't as many algae blooms since the environment wasn't as contaminated.
1.) People are more likely to report these sightings when they don't know much on the subject - If you look in the past, humans have been trying to create a reason for everything. When there was a natural disaster, and they didn't understand it, they said that the divine beings were angry. When people got lucky, they called it fate, or that they had the favor of the god/God/god(s). In the 1700s, the first algae bloom was reported. Of course, they didn't have enough information on the matter and tried to blame it on something. If they saw it again, they might take it as a bad omen and immediately report it. This would increase the percentage of blooms reported that happened around the civilization.
2.) There is a matter of population difference - In the 1800s, there was approximately one billion people in the world. This population is nearly two times the population in 1700 CE (population: 600 million). Of course, seeing as people started to migrate / spread out across the land, there would be more rivers/bodies of water that are near a civilization. This means that they should, hypothetically, have a larger number of blooms reported. (Note that it is a larger number and not percentage)
3.) Environmental Contamination - As the population rapidly grows, there is a lot more inventions, experiments, technology, and development happening. This also means that the over populated cities such as London would have worse sanitary conditions. (This statement applies only to the before bacteria & other microorganisms were discovered.) Improper disposal of waste would ultimately lead to land and water contamination, which results in more algae blooms appearing. Trash could have also gone to the middle of the ocean. Algae blooms that appear in the middle of the ocean most likely wouldn't get reported, as it isn't located near a civilization. In this case, the percentage would decrease, since the ratio would be off.
Conclusion:
There are many factors that are involved in this complicated problem. It is also impossible for me to decide which had more algae blooms reported, also because it wasn't specified whether the question was asking for the number or the percentage. Since I cannot properly answer this problem, I listed the major things to think about.

Plants can reproduce sexually and asexually. Which statement below best describes why one method might be more beneficial than the other?
O Sexual reproduction provides genetic variation to plants to help them survive in a changing environment.
O Asexual reproduction allows plants to avoid having to care for their offspring.
O Asexual reproduction allows plants to skip the process of finding a mate.
O Sexual reproduction guarantees that two plants will provide nourishment for new plantlets.
Answer:
Sexual reproduction provides genetic variation to plants to help them survive in a changing environment.
Explanation:
This would be the most beneficial because more plants would live if the environment changes. Things like finding a mate or more care for there offspring would not be as beneficial because it would not matter as much for the population. I think that having a good population would be the most beneficial.
Sexual reproduction provides genetic variation to plants to help them survive in a changing environment. So the correct option is A.
What is sexual reproduction?Sexual reproduction is the process through which two individuals of various sexes combine their genetic material to create new species. In the majority of organisms, reproductive cells called gametes, which mate to create a diploid zygote, have chromosomes in their nuclei that carry the genetic material. The zygote grows into a new person. The most common method of reproduction among living things is sexual reproduction.
A remarkable variety of children, each with a genetic make-up different from that of its parents, may occur from sexual reproduction because it permits the rearranging of genetic material both within and between members of one generation. With the exception of bacteria, all creatures that reproduce sexually share the creation of haploid, uninucleate gametes that combine during fertilization to create diploid, uninucleate zygotes.
The organism's chromosome count is once again decreased by meiosis at a later point in its life cycle in order to create the gametes for the following generation. A majority of forms have a big egg and a minute sperm; the gametes may be equal in size (isogamy) or one may be somewhat larger than the other (anisogamy) (oogamy).
Therefore the correct option is A.

can you consider having wavy hair as a case of incomplete dominance pattern?why you say so?
Answer:
Explanation:
Hair type is an interesting case of something called incomplete dominance. What this means is that with hair type, if you have one of each version of the gene, you get a mix of the two or wavy hair. So for hair type, CC gives curly, Cs gives wavy and ss gives straight hair. Back to your specific situation.
