The diffusion of a substance into or out of a cell requires
Answer:
Diffusion is one principle method of movement of substances within cells, as well as the method for essential small molecules to cross the cell membrane. Gas exchange in gills and lungs operates by this process. Carbon dioxide is produced by all cells as a result of cellular metabolic processes.
Explanation:
The diffusion of a substance into or out of a cell requires a process called diffusion, by which the molecules pass out through the plasma membrane.
What is diffusion?Diffusion is a key mechanism for material transfer within cells and for the passage of critical tiny molecules across the cell membrane. This process controls the exchange of gases in the gills and lungs. All cells release carbon dioxide as a byproduct of biological metabolism.
There are two processes by which the molecules pass through a semi-permeable membrane. The processes are osmosis and diffusion. When the material transfer from low concentration to higher concentration.
Thus, diffusion is the process by which molecules travel through the plasma membrane to allow material to enter or exit a cell.

Identify the structures a virus can contain.
Answer:
The simplest virions consist of two basic components: nucleic acid (single- or double-stranded RNA or DNA) and a protein coat, the capsid, which functions as a shell to protect the viral genome from nucleases and which during infection attaches the virion to specific receptors exposed on the prospective host cell.

What are Monosaccharides?
Monosaccharides are the monomers of carbohydrates. It is the energy storage in the body. Carbohydrates provide energy in the form of glucose.
A monosaccharide is a type of simple sugar that serves as the foundation for more complex sugars like polysaccharides and oligosaccharides. Fructose, glucose, and ribose are some examples.
Monosaccharide is an etymology term that means "one saccharide." Saccharides are the basic building blocks of carbohydrates.

how does water boiling on a stove represent all 3 types of heat transfer
Answer:
For example, when a pot of water is placed on the stove to boil, conduction heat warms up the pot, which then heats the water molecules inside. As these molecules heat, convection causes them to move away from the interior of the pot as they are replaced by cooler molecules.

Phenylalanine is required for the production of many bodily proteins, but none of your cells are capable of synthesizing this essential amino acid. What type of metabolic pathway must be responsible for providing phenylalanine to your cells? How would your diet effect the mount of Phenylalanine that is available?
Answer and explanation:
Phenylalanine is an amino acid that is very important for our bodies to function correctly but it isn't synthesized in our cells, so the only way to incorporate it is by having it in our diets, this is why phenylalanine is an essential amino acid.
Phenylalanine can be found in milk, eggs, chicken, and liver, among other foods known to be good protein sources. Given the fact that phenylalanine is an essential amino acid, the amount we ingest of it in our diet will directly impact on the availability of this amino acid in our body.
Phenylalanine is an amino acid and, as such, it will enter the metabolic pathway of protein catabolism, where it will be degraded to be fully usable for the body. Phenylalanine will be metabolized into acetoacetic acid and fumaric acid, and is the precursor of catecholamines such as epinephrine and norepinephrine, while also being part of the structure of several neuropeptides.
You need to find out why the GBR water is inhibiting (stopping) photosynthesis in the algae. The three major parts of photosynthesis are PSI, PSII and the Calvin cycle. The database has provided 3 things that could be inhibiting photosynthesis: high sea temperatures, paraquat, and diuron.
Answer:
Explanation:
The question is not complete below is the remaining part of the question
Justify your choice by writing a hypothesis to explain how it has stopped the algae from making ATP, NADPH and sugars. You will be able to revise your hypothesis as you do more experiments
Explanation:
The hypothesis will be
High sea temperature inhibit Algae growth
Herbicides reduces algae photosynthesis rate
Algae respond to temperature differently some thrive at a low temperature, some at a moderate temperature but when the temperature is very high the rate of photosynthesis will reduce because they can not undergo the normal body physiological function as a result of harsh environment. In green plant at a very high temperature stomata closes to regulate water loss this prevent Carbon dioxide from coming in and photosynthesis rate reduces
Paraquat and Diuron are herbicide that prevent the growth of plants, when they are sprayed Algae is affected they die from immediate action of this chemical and their colour changes since chloroplast the green pigment is where light hit for photosynthesis to occur when the color changes the active site is affected photosynthesis can no longer occur.
Answer:
Diuron
Explanation:
Increasing the temperature only decreases the sugar, not the ATP and NADPH. I predict that Diuron will be inhibiting photosynthesis because photosynthesis as a whole should not work if Photosystem II is interfered with. Also, because Paraquat only lowers NADPH and sugar and not ATP, Diuron is the only choice left.

Which of the following describes a second class lever
1. The fulcrum is located between the effort force and the load.
2. The effort force is located between the fulcrum and the load force.
3. The load force is located between the effort force and the fulcrum.
Answer:
I think the answer might be number 2
In the second class lever, the load is between the effort force and the fulcrum. The correct option is 3.
What is a fulcrum?The term can refer to the juncture or assistance on which a lever rotates, as well as the focal point of a critical activity or situation.
The term "fulcrum point" in zoology refers to an anatomical structure that serves as point of support.
The load in second-class levers lies among both the effort and the fulcrum. A wheelbarrow is a prominent example, where the effort moves a great distances to lift a substantial load, with the axle and wheel acting as the fulcrum.
In a second-class lever, the effort is distributed over a large area in order to raise the load a short distance.
Thus, the correct option is 3.

Each strand of s DNA molecule contains nitrogenous bases that pair with other nitrogenous bases in very specific ways. A diagram of a section of DNA is shown. DNDA Strand 3' _|___|___|___|___|___|___|___|___|___|___|___|___|_ 5' T G T A G C T G C G C G T Which DNA strand is complementary to the one shown above?
Answer:
The complementary DNA strand, according to the nucleotide sequence of the other strand is 3' - A C A T C G A C G C G C A - 5'
Explanation:
Each strand of DNA is made up of specific sequences of the four nucleotides present in this molecule, adenine, thymine, cytosine and guanine.
In double-stranded DNA, one strand complements the other —according to the complementarity of nitrogenous bases— where a purine, adenine and guanine, are joined with a pyrimidine, thymine and cytosine, respectively:
Adenine is complemented with Thymine. Guanine is complemented with Cytosine.According to this, the complementarity of the strands is:
5' - T G T A G C T G C G C G T - 3'
3' - A C A T C G A C G C G C A - 5'
The DNA strands remain linked by hydrogen bonds between their nitrogenous bases, until such time as they must be separated for transcription.

Which statement below is correct?
A. Photosynthesis produces ATP, and cellular respiration requires light
energy
B. Photosynthesis produces carbon dioxide, and cellular respiration
produces sugars.
C. Photosynthesis and cellular respiration occur in both plant and
animal cells.
D. Photosynthesis produces the oxygen required for cellular respiration.
Answer:
B is the correct answer.
A is incorrect because respiration is always occuring in animals and plants, therefore it means it does not require the presence of light. Photosynthesis does produce ATP, though.
Not C because photosynthesis does not occur in animals
Not D because they both are different processes. They don't really depend on each other, though they could occur at the same time.
