Explanation:
if humans run out of following resources, which resource would be most difficult to replace
Answer:
Petroleum
Explanation:
Like all fossil fuels, petroleum is a nonrenewable energy resource. This means that it is a resource that cannot be replaced as quickly as humans use up existing supplies. Humans face a problem because once petroleum reserves begin to run out, there won't be enough fuel to power all the automobiles in the world.
If an organism does not have a nucleus, has only one cell, and can survive in extreme conditions, into which domain would it be classified?
Question 8 options:
Domain Eukarya
Domain Archaea
Domain Bacteria
a particle of oxygen has 8 protons and 8 electrons. is this an atom or an ion? what's the charge?
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 :)
A particle of oxygen has 8 protons and 8 electrons in an atom and the charge on it is zero.
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.

The ____________________ is the reproductive structure of gymnosperms.
Answer:
seed cones and pollen cones
Explanation:
In gymnosperms, their reproductive structures include the pollen cones, which produce pollen grains or the male gametophyte; and the seed cones, which produce female gametophyte.
Answer:
The Answer Is "Cones"
Explanation:
Why? Well, the cones spread from the male cones to the female cones... Then, the female cones put this sticky stuff on the cone called, " Ovule" Finally, it creates the cycle once again.

What will happen to the red blood cell in this environment?
Group of answer choices
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.
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.

9. Which food would you expect to have the lowest lipid levels?
a. Olives
b. Pistachios
c. Wheat crackers
d. Sesame seeds
The food expect to have the lowest lipid levels is sesame seeds. The correct option is d.
What is lipid?Lipids are hydrocarbon-containing molecules that serve as the foundation for the structure and function of living cells.
Lipids include fats, oils, waxes, vitamins (such as A, D, E, and K), hormones, and the majority of the cell membrane that is not made of protein.
Carbon, hydrogen, and oxygen are the same elements found in lipids as they are in carbohydrates.
Lipids, on the other hand, are primarily composed of hydrocarbon chains and contain fewer polar hydroxyl groups. As a result, most lipids are nonpolar hydrophobic molecules.
Sesame seeds are high in saturated fat (15%), polyunsaturated fat (41%), and monounsaturated fat (39%).
According to research, eating more polyunsaturated and monounsaturated fat than saturated fat may help lower your cholesterol and reduce your risk of heart disease.
Thus, the correct option is d.

why are enhinoderms and cnidarians are more closely related than enchinoderms and mammals
Answer:
Because they are triploblastic ( Triblastica ).
Explanation:
Their body is composed of endoderm, mesoderm and ectoderm. While Cnidaria are Diblastica, so they are composed only from two layers: endoderm and ectoderm.
In addition larvae of Echinoderms are bilaterally symmetrical and they become nearly-radial only as adults.

What effect does burning fossil fuels during manufacturing and energy production have on outdoor air pollution?
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.
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.
Answer: The answer would be D!!
