Answer:
[tex]\boxed {\boxed {\sf A. \ Channel/Transport \ proteins}}[/tex]
Explanation:
The phospholipid bilayer is also known as the cell membrane. It covers cells and regulates the transport of substances. Certain ones can pass and others cannot, depending on certain factors like size and polarity.
Smaller substances tend to diffuse or move across the membrane quite easily. However, larger molecules have a much harder time. Many depend on special proteins embedded in the membrane. These are called transport proteins and they form a channel so large molecules can still move in or out of the cell.
So, salt, water, and fats do not contribute to the movement of larger molecules, but channel or transport proteins do and choice A is correct.
Read the passage. Then explain why the circulatory system of a grasshopper does not need to carry gases to and from the grasshopper's cells.
Passage
The diagram shows part of a grasshopper's respiratory system. Air passes into and out of openings in its sides. These openings are connected to tubes and air sacs that fill with air. The air tubes branch into tiny tubes that spread out and are found close to all cells. So, unlike other animals, the grasshopper does not exchange gases using its circulatory system.
PLS ANSWER ASAP
Answer:
In vertebrates, the circulatory system is responsible for transporting oxygen to all the tissues and removing carbon dioxide from them. ... In the grasshopper, exchange of oxygen and carbon dioxide occurs in the tracheal system. Hemolymph plays no part in the process.

multicellular organisms, control gene expression by regulation of - DNA translation
Answer:
Trp Operon.
Explanation:
Trp Operon determines to control gene expression by regulation of DNA translation. The trp operon is found in E. coli bacteria, is a group of genes that encode biosynthetic enzymes for the production of amino acid tryptophan. The trp operon refers to turned "on" when tryptophan levels are low whereas refers to turned "off" when tryptophan levels are high. The trp operon is controlled and regulated by the trp repressor.

How many nucleotides are required for a 459-amino acid polypeptide? Just enter the
number.
Answer:
The correct answer is 1377.
Explanation:
Peptides and proteins are made in the process of Translation. For this to happen, a molecule of mRNA containing a nucleotide sequence is read by a structure called ribosome. Each group of three nucleotides from the mRNA form a codon, and each codon has an anticodon in the tRNA molecule that will ultimately code for a specific amino acid (except for stop codons -when they appear in the sequence, translation stops-). Taking all of this into consideration, if 3 nucleotides lead to 1 amino acid, to have a 459-amino acid polypeptide it would require 1377 nucleotides (without counting the 3 nucleotides from the stop codon).

Which remains the same during a chemical reaction?
Answer:
In a chemical reaction the total mass of all the substances taking part in the reaction remains the same. Also, the number of atoms in a reaction remains the same. Mass cannot be created or destroyed in a chemical reaction
Because matter is not created or destroyed in a chemical reaction, the total mass of reactants is the same as the total mass of products.

It allows chemicals required for cellular respiration to enter the cell.
It regulates the movement of water into and out of the cell.
Which cell structure do these statements describe?
Answers:
A: endoplasmic reticulum
B: lysosome
C: mitochondria
D: plasma membrane
Answer:
b
Explanation:
The cell structure that allows waste to exit the cell is Lysosomes. It is the garbage disposal of a living cell. It eliminates all the waste materials through the process of degradation.
What do you mean by Cell structure?Cell structure may be defined as a structure that contains all those components with specific functions essential to carrying out life's processes.
The cell structure that allows chemicals required for cellular respiration to enter the cell is Mitochondria.
The cell structure that regulates the movement of water into and out of the cell is the Plasma membrane.

If there are 3000 calories of energy available at the zooplankton, how much energy will there be at the shark?
Answer:
30 calories of energy
Explanation:
In an aquatic ecosystem, zooplanktons are primary consumer i.e. they feed on primary producers e.g phytoplanktons. They are fed on by smaller fishes e.g tilapia, which in turn is fed on by sharks. Based on this, we have a food chain as follows:
phytoplankton → zooplankton → tilapia fish → shark
From this food chain, it appears that ZOOPLANKTON is a primary consumer while SHARK is a tertiary consumer. Since only about 10% of energy is transferred to each trophic level when organisms feed on one another, if there are 3000 calories of energy available at the zooplankton, the following will be available for sharks:
For secondary consumer = 10/100 × 3000 = 300 calories for tilapia fish
For tertiary consumer = 10/100 × 300 = 30 calories for shark.
Which of the following is true regarding Darwin's theory of evolution?
A. Acquired traits are always passed on to the offspring
B. Organisms develop favorable adaptations based on a need
C. Pure chance determines which species evolve
D. Individuals pass on adaptations to their offspring, due to natural selection
Answer:D
Explanation:
Evolution
Individuals pass on adaptations to their offspring, due to natural selection. The correct option is D.
What is Darwin's theory of evolution?The English naturalist Charles Darwin and others developed the Darwinism theory of biological evolution, which contends that all species of organisms arise and develop through the natural selection of minute, inherited variations that improve the individual's capacity for competition, survival, and reproduction.
Darwin claimed that all species share a common origin, that species can change through time, and that new species develop from existing ones.
Charles Darwin, a naturalist of the 19th century, investigated the theory of natural selection.
Natural selection provides an explanation for how a species' genetic features might evolve through time. This could result in speciation, or the creation of a new, separate species.
Thus, the correct option is D.

Oligomycin A is an antibiotic that works by blocking a proton (H ) channel in ATP synthase, inhibiting the action of the enzyme. The primary effect of this antibiotic is: Group of answer choices decreased ATP synthesis due to a decreased hydrogen ion gradient across the inner mitochondrial membrane. increased ATP synthesis due to an increased hydrogen ion gradient across the inner mitochondrial membrane. decreased ATP synthesis due to the inhibition of oxidative phosphorylation of ADP. increased ATP synthesis due to the promotion of oxidative phosphorylation of ADP.
Answer:
Decreased ATP synthesis due to the inhibition of oxidative phosphorylation of ADP
Explanation:
If the antibiotic inhibits the action of ATP synthase, it will decrease ATP synthesis.
ATP synthase has the main function of synthesizing ATP from the oxidative phosphorylation of ADP.
In oxidative phosphorylation, ATP is produced from the transfer of electrons from NADH and FADH2. A chemical gradient is created, allowing for ATP synthase to create ATP.
So, the correct answer is that there will be decreased ATP synthesis due to the inhibition of oxidative phosphorylation of ADP.
