Answer:
Write a paragraph about the doctor who discovered the working of stoma
In botany, a stoma (plural "stomata"), also called a stomate (plural "stomates") is a pore, found in the epidermis of leaves, stems, and other organs, that controls the rate of gas exchange. The pore is bordered by a pair of specialized parenchyma cells known as guard cells that are responsible for regulating the size of the stomatal opening.
The term is usually used collectively to refer to the entire stomatal complex, consisting of the paired guard cells and the pore itself, which is referred to as the stomatal aperture.[1] Air enters the plant through these openings by gaseous diffusion and contains carbon dioxide which is used in photosynthesis and oxygen which is used in respiration. Oxygen produced as a by-product of photosynthesis diffuses out to the atmosphere through these same openings. Also, water vapor diffuses through the stomata into the atmosphere in a process called transpiration.

Answer:
Imagine that you are seven years old. You are participating in an experiment. A
researcher greets you and shows you into a small room. In the room there is a
marshmallow. The marshmallow is for you, but here is the interesting part: The
researcher tells you that he is going to leave you alone in the room for a while. You can
eat the marshmallow right away, or you can wait until he gets back. If you wait until he
gets back, you will get a second marshmallow.
What do you do? Do you eat the marshmallow right away?
An experiment like this, known informally as the marshmallow experiment, was
conducted decades ago at Stanford University. It turned out that some children ate the
marshmallow right away, while others were able to wait. In other words, some sought
instant self-gratification, and some delayed it.
Years later, the researchers followed up on the participants. They found that the
children who delayed self-gratification were in general more successful than those who
ate the marshmallow right away. By a variety of measures, including SAT scores, they
appeared to be more competent.
Common sense tells us that the ability to delay self-gratification is a mark of maturity.
The marshmallow experiment provides evidence that it may also correlate with success
in life.
Notes:
- Many of these verb phrases consist of an auxiliary verb and a main verb. So, for
example, “are participating” and “do…eat” are considered verb phrases.
- “is going to leave”: If we consder “is going to” a kind of auxiliary verb, then this is a
verb phrase, just like “will leave.”
- “known as…”: If you underlined “known,” that’s fine. It is a verb. It is a nonfinite verb,
unlike the other underlined verbs and verb phrases. (See Chapter 4.)
■ Exercise 2 Underline the complete subjects in the sentences below, and double-
underline the verbs that go with them. Identifying the subject means identifying the
main word of the subject and the parts that modify it. (In the first sentence, the main
word is in boldface.) When you underline the verb, include both auxiliary verbs and
main verbs (as in the first sentence, with was…used).
In the 1960s and 70s, the term “generation gap” was often used to refer to the
differences between young people in the U.S. and their parents’ generation. Many
young people felt distant from their parents because of differences in ideas about
politics, social issues, and popular culture. Since then, conflicts between generations
have diminished in many ways. Child-rearing experts in the late 20th century
encouraged parents to be like friends to their children. Thanks to technology, young
people and their parents are able to contact each other easily at any time. On any
college campus, the students you see texting or talking on cell phones are often
communicating with Mom or Dad. Fifty years ago, closeness of this kind was less.
