The cells were first discovered when a scientist named Robert Hooke observed cell walls in cork under a microscope.
Who was Robert Hooke and what was his importance for cytology?Robert Hooke's observation made it possible to visualize the dead cell walls of cork, even without knowing what the image represented, exactly, and without relating living beings to a cellular composition.
In the beginning, the cell theory was elaborated by the scientist Robert Hooke, in the year 1665. Based on this research, the cell is a morphophysiological unit of all living beings, that is, it corresponds to the smallest unit of life.

The word in their names shows that two of the plants share the greatest number of features is marsh. Therefore, option A is correct.
What is marsh ?A marsh is a type of wetland where herbaceous plant species, not woody ones, predominate. The transition between the aquatic and terrestrial ecosystems is commonly formed by marshes, which are frequently found along the borders of lakes and streams. Grass, rush, or reeds frequently rule over them.
Cattails, sedges, papyrus, and sawgrass are typical examples. Most aquatic creatures, including fish and salamanders, can survive in water with little oxygen.
In a marsh, herbaceous plants make up more than half of the vegetation, and the pH of the soil is neutral. There are fewer than 30% woody plants in the area. Throughout the growth season, a marsh has standing water for extended periods of time.

Why did problems with low oxygen levels and increasing carbon dioxide levels develop in Biosphere?
The problem with low oxygen levels and increasing carbon dioxide levels develop in the Biosphere because the oxygen was absorbed by the population of microbes that are growing in an uncontrolled manner and some other concrete structures present in the Biosphere.
What is Biosphere?A biosphere may be defined as the areas of the surface and atmosphere of the earth or another planet inhabited by living organisms. It may also be regarded as the zone of life on earth.
The amount of carbon dioxide directly depends on the amount of oxygen. If the oxygen level reduces, the level of carbon dioxide will definitely tend to increase.
The level of oxygen accounted as low in the biosphere due to the microbial respiration to a larger extent. And thereby, the level of carbon dioxide increases.

There are six people in the Fisher family. Olivia and Marcus are the parents. They have four children: Violet, Nathan, Jonas, and Claudia.
Neither Olivia nor Marcus have freckles.
What is Olivia's genotype?
What is Marcus' genotype?
What is the probability that each child has of inheriting freckles?
Both Marcus and Olivia are heterozygous for the hairline trait.
What is the probability that each of their children could inherit a widow's peak?
What is the probability that each of their children could inherit a straight hairline?
What is the probability that each of their children could be homozygous dominant for the trait?
Neither Marcus nor Olivia can roll their tongues.
How many of their children could be born with the ability to roll their tongues?
How many of their children could be heterozygous?
What is the genotype of the whole family?
All four children have dimples.
What is likely the genotypes of their parents?
Do we know with certainty that one of the parents has to have dimples?
Both Olivia and Marcus are EE for the earlobe trait.
Among their children, what is the ratio of free earlobes to attached earlobes?
What percentage of the children are homozygous?
Marcus can not detect the bitter taste. Olivia has been found to be able to detect the bitter taste, but she is heterozygous for the trait.
What is the probability that each of their children could taste the ptc paper?
If Violet can not taste the ptc paper, what is Violet's genotype?
Given what you know, how many of the family can taste the ptc paper?
1.
Freckles are caused by a dominant allele (F).
Marcus and Olivia have recessive homozygotes for the characteristic, ff, if neither of them has freckles.
Olivia's genotype is thus ff.
Marcus has a ff genotype.
Given that they are both recessive homozygotes for the ff gene, there is little chance that their offspring will have freckles.
2.
The straight hairline allele, W is recessive to the widow peak allele, W.
Marcus and Olivia share the hairline trait heterozygosity Ww.
The likelihood of a widow having children is highest when:
Ww = Ww, Ww, Ww, and ww
Widow's peak probability (WW or Ww) equals 3/4
The likelihood that a youngster will have a straight hairline is 1/4.
The likelihood that the offspring will be homozygous
3.
The attached-lobule trait, e, is recessive to the free-lobule trait, E.
The trait, EE, is homozygous dominant in both parents.
One to zero is the ratio of free to connected lobes.
The offspring will be homozygous dominant free lobules, EE, in all cases.
4.
The ability to taste bitter flavors is dominant (T).
Marcus is a recessive homozygote for the trait "tt" since he cannot sense bitterness.
Olivia possesses a "Tt" heterozygote for the trait.
Tt tt equals Tt, Tt, tt, and tt.
There is a 50% chance that each of their kids will try the PTC paper.
Violet's genotype is tt since she cannot taste PTC paper.
5.
T, tongue rolling is a dominant characteristic.
Marcus and Olivia both have tt genotypes since neither of them can roll their tongues.
tt = tt = tt = tt
Therefore;
Their offspring won't be able to roll their tongues.
No hybrids will be born to them.
The entire family shares the genetic tt.
6.
A dimple is a dominant trait (D)
The four youngsters all have dimples.
Therefore,
It's possible that both of their parents carry the dominant allele for the characteristic "DD" or
One of them is heterozygous, or "Dd," and the other is homozygous.
The dominant h0m0zygote "DD" is one of them, while the recessive h0m0zygote "dd" is the other.
Therefore, at least one parent must have a dimple.
