Answer:
The cell membrane controls the substances that enter and exit the cell
Explanation:
The cell membrane defines the boundaries of the cell, separating the internal components from the external environment.
The membrane is a semi-permeable barrier that lets some substances in and out, but not others.
Therefore, the cell membrane controls many of the activities of the cell. As a result, it is crucial to maintain the normal functioning of the organism

what does DNA use to store information
Answer:
DNA stores biological information in sequences of four bases of nucleic acid — adenine (A), thymine (T), cytosine (C) and guanine (G) — which are strung along ribbons of sugar- phosphate molecules in the shape of a double helix.
Explanation:
DNA uses the complimentary base pairs to store information in organisms.
The base pairs comprises of the nucleic acid include adenine (A), thymine
(T), cytosine (C) and guanine (G) .
The base pairs contain unique amino acid sequences which represent a
unique trait in organisms. Any alteration in this pair will lead to a different
result or mutation which is why it is very important and has to be rightly
paired .

How do electromagnetic waves transfer energy?
A. They cancel vibrations in electric and magnetic fields,
B. They cause particles to move with them, WWW.
C. They cause vibrations in electric and magnetic fields,
D. They overlap electric and magnetic fields,
Answer: C
Explanation:
Electromagnetic waves transfer energy by they cause vibrations in electric and magnetic fields.
What do you mean by electromagnetic waves?Electromagnetic radiation consists of waves of the electromagnetic field, which propagate through space and carry momentum and electromagnetic radiant energy. It includes radio waves, microwaves, infrared, light, ultraviolet, X-rays.
Electromagnetic waves or EM waves are waves that are created as a result of vibrations between an electric field and a magnetic field. In other words, EM waves are composed of oscillating magnetic and electric fields.
Electromagnetic radiation exhibits wavelike properties such as reflection, refraction, diffraction, and interference, but also exhibits particlelike properties in that its energy occurs in discrete packets, or quanta.

What is the function of the plasma membrane? a Sorts proteins and then packs them into vesicles b It is a flexible boundary outside of the cell wall c Protection for the plant cell d It allows nutrients to enter the animal cell and wastes to be removed
Answer:
The correct option is d
Explanation:
Plasma membrane (or cell membrane) is a semipermeable or selectively permeable barrier that regulates what goes in and out of the cell by keeping toxic substances out of the cell while allowing nutrients, ions and some metabolic products inside the cell.
This membrane surrounds all the content/organelle inside (cytoplasm and nucleoplasm) of the cell.

1 poin Students are discussing what they know about cellular transport. Their explanations are displayed in the table. Which student(s) gave an accurate statement regarding cellular transport? * EXPLANATION Passive transport is the movement of molecules from high to low concentration. 2 The sodium-potassium pump is an example of active transport because it uses energy 3 Molecules move against the concentration gradient in passive transport. 4 Diffusion and osmosis are both examples of passive transport. O Student 1 only O Students 1 and 2 Students 1, 2, and 4 O Students 2, 3, and 4
Answer:
Students 1, 2 and 4
Explanation:
Passive transport goes from the higher concentration to the lower concentration in favor of the concentration. Student 3 referred to this as active transport and that is not right.
Simple passive diffusion, facilitated diffusion (via channels and carriers), and active transport are the fundamental forms of membrane transport. A bilayer membrane requires energy to flow through, even with simple passive diffusion. Thus, option C is correct.
What are the cellular transport mechanism in cell?The molecules will migrate from a lower concentration to a greater concentration during active transport.
Energy in the form of ATP is needed for this cellular transport molecule to function. Based on their purpose, the active cellular transporters are divided into four categories.
The sodium-potassium pump in the human body serves as a practical illustration of active transport. Here, potassium ions remain inside the cell while sodium ions are outside the cell.
Therefore, Exocytosis, endocytosis, antiport pumping, and symport pumping are the different types of active transporters.

Explanation:
Do you think partial melting will occur if the pressure is high in the asthenosphere?
Answer:
Partial melting occurs when only a portion of a solid is melted. For mixed substances, such as a rock containing several different minerals or a mineral that displays solid solution, this melt can be different from the bulk composition of the solid. Partial melting occurs where the solidus and liquidus temperatures.
Explanation:
No, partial melting will not occur if the pressure is high in the asthenosphere.
This is because the high pressure and temperature causes full melting of materials. In the asthenosphere, the melting point of rocks is lower than their melting point so that's why the partial melting of materials occur.
If the temperature and pressure increase than full melting of materials occur than the material will turn into a complete liquid state so we can conclude that at high pressure, partial melting will not occur.

Nucleic acids include DNA and RNA, are the genetic material in living things. The main function of the nucleic acids is to store and transmit the genetic information. Thus, the correct option is A.
What are Nucleic acids?Nucleic acids are biopolymers, which are essential to all known forms of life. They are composed of nucleotide polymers. Nucleotides are the monomers of nucleic acids which are made up of three components: a 5-carbon sugar, a phosphate group and a nitrogenous base. The two main classes of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
Nucleic acids play essential roles in all cells and viruses. The main function of nucleic acids involves storage and expression of genetic information in organisms. Deoxyribonucleic acid (DNA), encodes the information cells need to make proteins.
