What cell part supports the structure of the system plant cell

Answers

Answer 1

Answer:

The cell wall provides strength and support to the plant, much like the exoskeleton of an insect or spider (our skeleton is on the inside of our body, rather than on the outside like insects or spiders). The plant cell wall is mainly made up of the carbohydrates molecules cellulose and lignin.

The red blood cell will swell from absorbing salt molecules.

The size of the red blood cell will remain constant.

The red blood cell will swell at first and then shrink.

The red blood cell will shrink from losing water molecules.

Answers

Answer:

Explanation:

A The size of the red blood cell will remain constant. B The red blood cell will swell at first and then shrink.

The red blood cell in this environment is the red blood cell will swell from absorbing salt molecules. Thus, option A is correct.

What is the salt concentration of red blood cell?

The red blood cell has a lower salt concentration than the liquid which means that it has a higher water concentration than the liquid. By the process of osmosis, water will flow from the red blood cell to the liquid which would lead to the red blood cell shrinking in size.

Cellular respiration has used to create energy for cells. It works by burning glucose in the presence of oxygen. The result is an outburst of energy and [tex]CO2[/tex] as well as water. Red blood cells that are bathed in blood neither shrink nor swell and burst because the concentration of the surrounding blood is equal to the concentration inside the cytoplasm of the red blood cells. This means that the two solutions are isotonic.

Therefore, The red blood cell in this environment is the red blood cell will swell from absorbing salt molecules. Thus, option A is correct.

What is sickle cell anemia?

The sickle cell anemia is one of a group of inherited disorders known as the sickle cell disease. It affects the shape of the red blood cells which carry oxygen to all parts of the body. In sickle cell anemia some red blood cells are sickle shaped.

Red blood cells are usually round and flexible, so that they move easily through blood vessels. The sickle shaped red blood cells are also called crescent moons. These sickle cells also become rigid and sticky which slow or block the blood flow.

SCD causes a basal substitution of adenine A to thymine T in the sixth codon of beta globin. This leads to the replacement of glutamic acid with valine in polypeptide chains of haemoglobin.

3. (a) The binomial naming system used to identify all living things gives the Indian elephant
a scientific name of Elephas maximus.
Which part of this name refers to the genus and which part refers to the species?
genus
species
[1]​

Answers

Answer:

Genus = Elephas

Species = maximus

Explanation:

Carolus Linnaeus, who is considered to be the FATHER OF TAXONOMY for his immense contribution to the classification of living organisms. Carolus Linnaeus between the year 1735 and 1758, developed a scientific system of naming organisms using two-way naming system called BINOMIAL NOMENCLATURE.

The two Latin names given to organisms were derived from their generic and specific epithet i.e. one of the names is GENUS and the other SPECIES. According to this question, the scientific name using the binomial naming system for Indian elephant is Elephas maximus. This means that Elephas is the part that refers to GENUS while maximus is the part that refers to SPECIES.

What effect does burning fossil fuels during manufacturing and energy production have on outdoor air pollution?

Answers

Answer:

It causes global warming as well as air pollution.

Explanation:

Burning of fossil fuels has adverse effect on outdoor air pollution because when the fossil fuels burns carbondioxide gas is released in the atmosphere. Carbondioxide gas is a greenhouse gas which is released in the atmosphere through burning of fossil fuels and is responsible for increasing air pollution. This increase in carbondioxide gas leads to global warming due to blockage of solar radiation that is reflected from the earth surface.

Some students conduct an investigation in a biology lab by setting up four different artificial stomachs, each in a
40 °C water bath. The students place the same amount of boiled egg white, a protein-rich source, in each stomach.
They also add dilute hydrochloric acid, HCl, and pepsin, a digestive enzyme, to each stomach, as shown in the table.
The students observe the mass of egg white in each stomach every 15 minutes.
Which statement describes the most likely result of this investigation?
A. The mass of the Egg white increases as the volume of the enzyme increases.
B. The egg white is unaffected by the differing amount of enzyme.
C. Digestion decreases in each stomach as more of the egg white's surface area becomes exposed.
D. Digestion increases as the volume of the enzyme increases.

Answers

Answer: D. Digestion increases as the volume of the enzyme increases.

Explanation:

Enzymes speed up reactions by reducing the activation time of a reaction. If there are more enzymes therefore, the reaction will move faster.

Pepsin is an enzyme that prefers acidic conditions so it can work with dilute HCL. It can also work in temperatures of 40 °C without getting denatured. As more Pepsin is added therefore, the reaction will move faster and digestion will increase.

a particle of oxygen has 8 protons and 8 electrons. is this an atom or an ion? what's the charge?

Answers

Answer: It is Atom and the charge would be postive.

Explanation: If the atom had 8 protons and 8 electrons (oxygen for example), knocking one of the electrons out, makes 8 protons and 7 electrons. The atom now has a net charge of +1 because the 7 electrons cancil the positive charges of 7 of the protons in the nucleus, but there is one remaining proton with a positive charge.Oxygen's 8 electrons are negatively charged, and they orbit the atomic nucleus and balance the positive charge of the 8 protons. The positive charge of 1 proton exactly cancels the negative charge of 1 electron. Answer 9: Oxygen is atomic number 8 on the periodic table, which means it has 8 protons!

Hope this helps :) Can u plz mark me branliest :)

What is an atom?

It is the smallest particle of matter composed of electrons and a nucleus of protons and neutrons.

What is an ion?

It is an atom with a positive or negative charge due to either loss or gain of electrons.

Every atom tends to have a noble gas configuration for stability and they either tend to lose, gain, or share electrons to achieve it.

The oxygen atom generally gains 2 electrons to complete its octet and has a net -2 charge.
