The cell membrane controls the rate at which molecules, such as water and oxygen,
enter the cell to maintain homeostasis. This rate is determined by the -
F permeability of the cell membrane
G mass of the nucleus
H stage of the cell cycle
J primary function of the cell

Some solutes move freely across cell membranes, while other solutes require
assistance from special gates. Passive transport and active transport are methods of
moving solutes across cell membranes.
Which of the following accurately describes the difference between passive transport
and active transport?
A Passive transport can move molecules both in and out of a cell, but active transport
cannot.
B Passive transport works against a concentration gradient, but active transport does
not.
C Passive transport does not require energy, but active transport does.
D Passive transport requires carrier proteins, but active transport does not.
Answers
Answer:
the first one is F, the permeability. the second is C
Question 4: The permeability of the cell membrane determines the rate at which molecules enter a cell.
Question 5: The statement that describes the difference between passive and active transport is "Passive transport does not require energy, but active transport does"
CELL MEMBRANE:
The cell membrane is the organelle that bounds the cell and its component.The cell membrane is referred to as a semipermeable membrane because it selectively allows the passage of molecules in and out of the cell. However, the rate at which molecules enter a cell is determined by the permeability of the cell membrane. The cell membrane is permeable to some molecules but not permeable to others.CELLULAR TRANSPORT:
The transport of substances in and out a cell can be of two types namely: active transport and passive transport. Active transport is the type of transport that involves the use of energy in form of ATP. In active transport, substance move against a concentration gradient. On the other hand, passive transport does not require energy input because movement of substances occur down a gradient. Therefore, the statement that describes the difference between passive and active transport is "Passive transport does not require energy, but active transport does".Learn more at: https://brainly.com/question/18067330?referrer=searchResults

Which of the following correctly characterizes one of Earth's atmospheric layers?
A
Layer A is the stratosphere, where meteors are found.
B
Layer B is the troposphere, where weather occurs.
с
Layer C is the stratosphere, where the ozone layer is found.
D
Layer D is the thermosphere, where auroras are found.
Answers
Answer:
it is A layer A is the stratosphere where meteors are found
Explanation:
Answer:
It is Layer D
Explanation:
It would not be a because the first layer is not stratosphere but troposphere. It would not be b because layer b should be the stratosphere. It would not be c because layer c should be mesosphere not stratosphere. Which leads us to the only answer choice that is left answer choice D.
According to the base-pairing rules of DNA, if the sequence of bases on one strand was CGGCTTA, what would be the sequence of based on the complementary strand?
Answers
Answer:
GCCGAAT
Explanation:
Deoxyribonucleic acid, also known as DNA, is a molecule that serves as the genetic material in living organisms. It is a double-stranded molecule made up of nucleotides subunits. The nucleotides, which are Adenine (A), Guanine (G), Cytosine (C) and Thymine (T) on each strand are held together using the COMPLEMENTARY BASE PAIRING RULE.
The complementary base pairing rule states that an Adenine base will always hydrogen bond with Thymine base while Guanine will always bond with Cytosine base i.e. A-T, G-C. Based on the rule, a DNA strand with sequence: CGGCTTA will have a complementary sequence of GCCGAAT on the other strand.
Why would a plant not grow well in green light?
Answers
Answer:
green light is not real light plants need the sun which produces real energy
Green light is the least effective for plants because they are themselves green due to the pigment Chlorophyll. Different color light helps plants achieve different goals as well. Blue light, for example, helps encourage vegetative leaf growth. Red light, when combined with blue, allows plants to flower.

In an animal cell, DNA may be found
in the nucleus, mitochondria, and rough ER.
only in the nucleus and rough ER.
only in the nucleus and mitochondria.
only in the nucleus.
Answers
Answer:
Se encuentra dentro del núcleo
Explanation:
In an animal cell, DNA may be found Only in the nucleus. Therefore option D is correct.
In an animal cell, DNA is primarily found in the nucleus, which is the cell's control center.
The nucleus houses the cell's genetic material, including DNA, which carries the instructions for the cell's growth, function, and reproduction. The DNA in the nucleus is organized into structures called chromosomes.
While mitochondria and rough endoplasmic reticulum (ER) are important organelles involved in various cellular functions, they do not contain the cell's primary genetic material.
Mitochondria have their own small amount of DNA, but this DNA is separate from the nuclear DNA and is involved in mitochondrial functions. Rough ER is involved in protein synthesis and transport but does not house DNA.
Therefore option D only in the nucleus is correct.

Place the four images from the cell cycle in the correct chronological order.
A, D, B, C
C, D, B, A
C, B, A, D
B, C, D, A
Answers
Answer:
C, B, A, D
Explanation:
The images in this question is portraying the stages involved in MITOSIS, which is a kind of cell division that forms two genetically identical daughter cells. The four stages of mitosis represented in the image are as follows: interphase, prophase, metaphase, and anaphase
- INTERPHASE: This stage is regarded as the resting stage of the cell. The chromosomes are found to be supercooled together as chromatins as seen in image C.
- PROPHASE: In the prophase stage, the chromosomes become condensed and more visible as seen in image B.
- METAPHASE: In the metaphase stage, the chromosomes align at the equator of the cell in order to be pulled apart by microtubules as seen in image A.
- ANAPHASE: In the Anaphase stage, the chromosomes are pulled apart into opposite poles of the cell as depicted in image D.
The images of the cell cycle in the correct chronological order would be C, B, A, D.
The order of the cell cycle is from the interphase to the m phase.
The interphase order is:
G1 phase - cell growth and developmentS phase - DNA synthesisG2 - protein synthesisThe m phase order is:
Prophase - nuclear envelope dissolves, chromatin condensesMetaphase - chromosomes align at the equatorAnaphase - sister chromatids are pulled apart and migrate to opposite polesTelophase -migration of sister chromatids completeIn the image:
A - metaphaseB - S phase C - G1 phaseD - telophaseHence, the order would be C, B, A, and D.

Answers
The function of the integumentary system is that it grows new tissue.
The integumentary system is know as the largest organ system of the body. This is also called skin. The two main layers of the skin includes
epidermis anddermisThe epidermis is the most superficial layer of the skin. The maintenance of a healthy epidermis helps protecting the body and it depends upon three processes being synchronised:
desquamation(shedding) of the keratinised cells from the surfaceeffective keratinisation of the cells approaching the surfacecontinual cell division in the deeper layers with newly formed cells being pushed to the surface.Therefore, the function of the integumentary system is that it grows new tissues in the epidermis layer which helps in the protection of the body.
