Explanation:

Algae are a group of living organisms classified under the kingdom Protista. They exhibit unique characteristics such as mode of reproduction, type of pigment, food reserve material, locomotive ability etc.

A british scientist (botanist) named Felix Eugen Fritsch in 1935 classified algae into 11 different classes based on some of these characteristics. The classes of algae are as follows:

1. Chlorophyceae (green algae)

2. Xanthophyceae (yellow green algae)

3. Chrysophyceae

4. Bacillariophyceae (diatoms)

5. Cryptophyceae

Answer:

- An element is a pure substance that cannot be broken down into a simpler form.

- All elements are listed on the periodic table of elements.

- An element symbol begins with a capital letter; if there is a second or even third letter, it is a lowercase letter

Explanation:

An element is one of the two types of pure substances i.e. substances that cannot be broken down into simpler forms. Elements are made up of only one type of atom e.g. Fe, Cl2 (two chlorine atoms).

All known or discovered chemical elements are represented on the periodic table. In an order of increasing atomic number, elements are arranged from left to right on the periodic table.

The symbol of an element begins with a first letter written in capital letters while the subsequent letters can be written in lower cases. For example, Fe, Cu, Hg, Zn etc.

Group of answer choices a compound that inhibits enzymes by significantly changing the pH throughout the body a drug to treat diabetes that irreversibly inhibits an enzyme in the metabolic pathway to synthesize glucose a drug to treat high blood pressure that reversibly inhibits an enzyme catalyzing production of a chemical that causes blood vessels to contract a compound that acts as a competitive inhibitor for a digestive enzyme produced only in the presence of certain foods

Answers

Answer:

The correct answer is - a drug to treat high blood pressure that reversibly inhibits an enzyme catalyzing production of a chemical that causes blood vessels to contract.

Explanation:

In the given all the situation or conditions that is practical and possible it the drug that develop to treat high blood pressure by reversibly inhibiting an enzyme that catalyzes the chemical that leads to constirctions of the blood vessels.

These chemical cause blood vessel constrict and that leads to high blood pressure therefore inhibiting such enzyme that use to produce these chemical is a practicle solution for high blood pressure.

Answers

Answer:

There is no scientific evidence to prove that people with schizophrenia ingest dopamine capable of accumulating excess in the body.

Explanation:

Although you did not specify that your question is associated with the origin of schizophrenia in people, we can see that this is the main topic of your question, due to its context. This is because scientists have been striving to find the origin of this disease, in order to be able to combat it in the early stages. Although many scientists believe that the origin of this disease is associated with excessive intake of dopamine, there is not strong enough scientific evidence to show that this is true. Because of this lack of evidence, filmmakers have focused on associating the origin of the disease with the sensitivity of the dopamine receptor and not with the dopain itself.

observe the given relation and fill in the blanks cucumber: tendril citrus: meiosis: reduction division mitosis:​

Answers

Answer:

citrus: thorns

mitosis: equational division

Explanation:

From the relationship:

Tendrils are thread-like appendages found in most climbing plants. They primarily function as supporting organs for climbing plants (such as cucumber) by stretching out and twinning around physical supports. The equivalence of this in citrus is the thorn.

Meiosis is a reductional cell division in which the chromosome number of the daughter cells is half of that of the other cells. Mitosis is equational division because the chromosome number of the parent cell is the same as that of daughter cells.

Answers

Answer:

Las leyes de Mendel son leyes que describen la herencia de rasgos hereditarios. Las leyes forman la base de la genética clásica. Asumen que cada individuo posee dos alelos para el mismo rasgo y los recibe al azar de los cuatro alelos diferentes de los padres. El fenotipo (apariencia física) del individuo depende de cuál de los dos alelos es dominante y cuál es recesivo. Dado que los individuos pueden transmitir ambos alelos a su descendencia, la descendencia incluye tanto individuos con fenotipo dominante como recesivo.

Question 2 of 10
Which of the following should be included in a good conclusion?

Answers

Answer:

How to write a conclusion

An effective conclusion is created by following these steps:

Restate the thesis: An effective conclusion brings the reader back to the main point, reminding the reader of the purpose of the essay. However, avoid repeating the thesis verbatim. Paraphrase your argument slightly while still preserving the primary point.

Reiterate your supporting points: Aside from restating your thesis, you should also reiterate the points that you made to support it throughout the paper. But instead of simply repeating the paper's arguments, summarize the ideas.

Make a connection between your opening and closing statements: It's often effective to return to the introduction's themes, giving the reader a strong sense of conclusion. You can accomplish this by using similar concepts, returning to an original scenario or by including the same imagery.

Provide some insight: Your conclusion should leave the reader with a solution, an insight, questions for further study or a call to action. What are the implications of your argument? Why should anyone care? You'll want to answer these types of questions here and leave your audience with something to think about.

This is an example of a(n) __________. concentration gradient pressure gradient electrical gradient temperature gradient

Answers

Answer:

pressure gradient

Explanation:

The correct answer would be pressure gradient.

A pressure gradient is created when there is a difference in the amount of pressure between two points or locations that are adjacent to one another.

In this case, the two locations that are adjacent to one another are the inside and outside of the lung. When one breathes in, the pressure inside the lung is more than that of the outside and the lung expands as a result. When we breathe out, the pressure outside is more than that of the inside and the lung collapses.

The sacrum is a bone formed by the sacral vertebrae, which have fused to give this bone. Above it articulates with the lumbar vertebra, below with the coccyx, which is the last section of the vertebrae column. Lastly, it articulates with the ilium at the sides. The ilium is one of the three bones that makes the hip bone. It is the largest one and in the upper part of the hip bone.

The ischium and pubis, which are the other two bones that form the hip bone, do not articulate with the sacrum, but they articulate with the ilium and with each other.

Woman's genotype : AO or

[tex] { | }^{a} i[/tex]

When

the children can not have O blood

The children cannot have B blood

means the man have BO

[tex] { | }^{b} i[/tex]

and woman have AA

[tex] { | }^{a} { | }^{a} [/tex]

Because

if man have BB, and woman have AA

children can only have AB

if man have BB, and woman have AO

The DNA of a prokaryote is arranged in a single coiled chromosome located in a region called the ____________ . Some prokaryotes carry genes on extrachromosomal pieces of circular DNA called ____________ .

Answers

Answer:

1. Nucleoid

2. Plasmid

Explanation:

Prokaryotes are groups of organisms characterized by the lack of a membrane-bound nucleus in their cell. Due to this, the genetic material (DNA) of prokaryotes are found naked i.e. not housed. The DNA of a prokaryote is arranged in a single coiled chromosome located in a region of the cell called NUCLEOID.

However, some prokaryotes e.g. bacteria carry genes on extrachromosomal pieces of circular DNA called PLASMID. Plasmids carry certain genes like antibiotic resistance genes.
