The option (C) is correct. Algae.
What are algae?Algae are defined as a group of predominantly aquatic, photosynthetic, and nucleus-bearing organisms that lack the true roots, stems, leaves, and specialized multicellular reproductive structures of plants.
Moreover, algae is an informal term for a large and diverse group of photosynthetic eukaryotic organisms. It is a polyphyletic grouping that includes species from multiple distinct clades.
Hence, algae are photosynthetic creatures. They are neither plant, animal or fungi. Many algae are single celled, however some species are multicellular. Many, but not all of red and brown algae are multicellular.

Which step happens first in DNA replication?
Answer:
Initiation
Explanation:
The initiation of DNA replication occurs in two steps. First, a so-called initiator protein unwinds a short stretch of the DNA double helix. Then, a protein known as helicase attaches to and breaks apart the hydrogen bonds between the bases on the DNA strands, thereby pulling apart the two strands. As the helicase moves along the DNA molecule, it continues breaking these hydrogen bonds and separating the two polynucleotide chains (Figure 1).

Evaluate the neighbor's arguments in the following scenario. Are there facts he is overlooking?
An elderly neighbor says today's girls are less mature than they used to be. He says it used to be that by the time a girl had a mature body, she had
a mature brain to go along with it. The neighbor argues that it all comes down to bad parenting and too much television.
Answer:
He is trying to explain that girls in his day had more respect for their self than they do not
Explanation:
They copy what they see on tv, school,and friends
Answer:
First of all, every child develops and matures on their own pace (within a certain range) and we can't compare one person to another. Secondly, in general, girls are reaching puberty earlier than they used to, which may stem from nutritional or environmental influences. For example, in 1900, the average age of puberty for girls was fifteen; today, it is twelve and a half. Moreover, attaining puberty or having a mature body doesn't result in a mature or fully developed brain. The brain continues to develops on its own pace from the rest of the body, until into adulthood to the age of twenty-five.

Suggest a molecular fix for a mutated CFTR channel. How would you correct it if you had the ability to tinker with it on a molecular level?
Answer:
normal and the mutant CFTR protein. How would you correct the mutant protein if you had the ability to tinker with it on a molecular level?
Corr-4a (bisamionomethylbithiazole C4) and VRT-325 were the first CFTR correctors discovered (quinazolinone C3 ). They are not, however, specific for CFTR and have been found to have low efficacy and high toxicity.
What is CFTR correctors?Correctors are the type of CFTR modulator even a small molecule that binds to CFTR and improves its functionality. is referred to as a "corrector."
Correctors assist the CFTR protein in forming the proper 3-D shape so that it can move or traffic to the cell surface.
And over 1,700 CFTR gene mutations have been discovered. Some are common, while others are uncommon and found in only a few people.
A CF corrector is a chemical chaperone that increases F508del-CFTR levels on the cell surface.
VX-809 (lumacaftor) is the most effective symptomatic CF corrector to date, according to a series of CF correctors.
Thus, these are some molecules that can fix mutated CFTR channel.

What factors are important in judging how helpful an energy resource is to us?
The factors which are important in judging the help fullness of energy resources to us are demand, storage of gas, weather forecast, nuclear and coal.
What are the important factors in judging the helpfulness of energy?The first factor is demand for heating, cooling, light, and processes varies in response to demand in terms of economic, technological, and efficiency measures. The second factor is Gas Storage and this has a term for energy “inventory” (since you can’t store electricity), i.e. the difference between supply and demand. Gas injections and withdrawals are announced weekly, and prices adjust accordingly.
The third factor is weather forecasts that is used to predict the weather events which are important considerations, affecting spot market prices and short-term contracts. Weather the forecast becomes reality is less critical to longer-term prices and last is generation changes while seemingly more localized, these changes can have a broad effect on the markets.

A scientist could best determine which ion (F-, Cl-, Br-, or I-) produced the greatest electrical potential in the Experiment by comparing the electrical potential that develops between ice and:
a solution of each sodium salt at the same concentration.
a single sodium salt solution at different concentrations.
a single sodium salt solution at different temperatures.
droplets of sodium salt solutions at different collision rates.
Answer:
a solution of each sodium salt at the same concentration
Explanation:
If a scientist wishes to study the electrical potential that develops between ice and the sodium salts solution of the ions (F-, Cl-, Br-, or I-) in order to determine which ion produced the greatest electrical potential; he must compare the electrical potential that develops between ice and a solution of each sodium salt at the same concentration.
This means that conclusions can not be reached unless the sodium salt of each ion at the same concentration is compared so as to ensure consistence in the results of the study.

EVALUATE The following statement. Erosion is a constructive process and deposition is a destructive process. Do you agree? Explain. :)
Answer:
Erosion is always destructive
Explanation:
This statement is not true as erosion is always a destructive process.
What is erosion?Erosion is the geological process in which earthen materials are worn away and transported by natural forces such as wind or water. It is an action of surface processes that removes soil, rock, or dissolved material from one location on the Earth's crust, and then transports it to another location where it is deposited. It is distinct from weathering which involves no movement.
Moreover, it is the movement of particles away from their source. Example of erosion: Wind carries small pieces of rock away from the side of a mountain. Chemical Weathering: – Decomposition of rock and soil due to chemical reactions.
Hence, erosion is a destructive process while deposition is a constructive process.

What would happen if cytokinesis did not work properly?
1) DNA replication would not occur
2) A cell would have a nucleus with too many chromosomes
3) A cell would have two nuclei
4) New daughter cells would not have enough organelles or would be missing organelles
5) a cell would be smaller in size
Answer:
If cytokinesis did not occur during mitosis the cytoplasm wouldn't be divided and there wouldn't be two identical daughter cells as a result. so the cell would remain to be at rest not being able to separate into two individual cells
