List the following structures from largest to smallest: proton pump, nuclear pore, cyt c ribosome,
nucleus.
Answer:
Nucleus
Nuclear pore
Proton pump
Cyt C Ribosome
Explanation:
The nucleus of the cell is the largest of all of these structures, all of the others are located inside the nucleus of the cell or interact with it, the nuclear pore is a pore in the nucleus that allows the transport of proteins through the membrane, the proton pump passes through the nuclear pore, and a Ribosome is a protein that transports nutrients, so that would be the smallest.
The order from largest to smallest is nucleous>> >> ribosome >> nuclear pore >> proton pump >> Cyt C.
The nucleus is the organelle that contains the genetic material in a eukaryotic cell, whereas ribosomes are protein factories.The nuclear pore is a structure that allows the passage of certain molecules between the cytoplasm and the nucleus.The proton pump is an integral protein-membrane, whereas Cyt C is a mitochondrial protein.In conclusion, the order from largest to smallest is nucleous>> >> ribosome >> nuclear pore >> proton pump >> Cyt C.

Many male birds will expend a great deal of energy building nests. Females will mate with the males who build the best nests. This is best described as an example of ____.
a. natural selection
b. sexual selection
c. runaway selection
d. an invasive species
e. disruptive selection
Answer:
The correct answer is option B. sexual selection.
Explanation:
Sexual selection is a special type of natural selection proposed by Charles Darwin. According to this type of natural selection in which a particular sex organism chooses the opposite sex member of the species to mate with on the basis of the preferable traits and compete with the other members of the opposite sex.
Here female birds choose those male birds who build the best nests, it is an example of natural selection.

how do you find per capita growth rate over a month?
All you have to do is take the CGR (capita growth rate) percentage you just found and divide it by the number of years, months, etc. The complete formula for annual per capita growth rate is: ((G / N) * 100) / t, where t is the number of years.

They lower the activation energy of the reaction
They increase the number of available reactant particles
They absorb energy from the products
They provide energy to the reactants
Answer:
They lower the activation energy of the reaction
Explanation:
Enzymes are proteinous biochemical molecules that serve as catalyst in living systems. They speed up the rate of biochemical reactions by lowering the activation energy of the reaction they are involved in.
As this question describes, enzymes possess an active site, which the substrate binds to yield products. The enzymes make the reaction faster by reducing the activation energy of the reaction, which is the energy needed to start a reaction.

A biochemist extracts a molecule from a cell. This molecule catalyzes a chemical reaction. To what class of molecules does it belong?
A. Proteins
B. Carbohydrates
C. Lipids
D. Nucleic acids
Answer:
proteins create enzymes which speed up reaction
Enzymes are the molecules that catalyze biological reactions, while a catalyst is a material that aids in the occurrence of a chemical reaction, hence option A is correct.
How do enzymes catalyze chemical reactions?The crucial function of decreasing the activation energy of chemical events inside the cell is carried out by the majority of enzymes, which are proteins.
Enzymes are biological catalysts that significantly speed up reaction rates and have the propensity to be particular about particular reactants and products, a substrate is a term for the reactant in an enzyme-catalyzed process.
Proteins are called enzymes to catalyze biological reactions that would not occur without them. For chemical reactions like digestion and cellular metabolism, these enzymes are necessary.
Therefore, since enzymes are a specific type of protein that catalyzes chemical events inside cells, they are excellent therapeutic targets, hence option A is correct.

Describe how a rainforest can reach a point when it cannot be restored by secondary ecological succession
Answer:Although the secondary forest will be low in diversity and poorly developed, the forest cover will be adequate for some species to return (assuming they still exist). The solution must be based on what is feasible, not overly idealistic, and depends on developing a new conservation policy built on the principle of sustainable use and development of rainforests. Beyond the responsible development of rainforests, efforts to rehabilitate and restore degraded forest lands along with the establishment of protected areas are key to securing rainforests for the long-term benefits they can provide mankind.
Explanation:
i lloke dit up online because i have not did this yet
A very high damaged leads to no restoration of rainforest by secondary ecological succession.
A rainforest can reach a point when it cannot be restored by secondary ecological succession when the large portion of the rainforest is destroyed and most of diversity is vanished. At this time, restoration is impossible due to very high damages.
Ecological resilience is the ability of an ecosystem to be restored through secondary ecological succession after a severe disturbance. Rainforest have a high biodiversity that helps it to resist damage but at a certain limit so we can conclude that very high damaged leads to no restoration of rainforest by secondary ecological succession.

Random mutations can occur in an organism's DNA, causing traits that are different from other organisms in that species. Sometimes these mutations can cause problems for the organism, but other times they are beneficial. What is a possible benefit to a random mutation in an organism?
Answer: It can increase an organism’s chances of surviving
Explanation:
how do mutations affect our communications?
Explanation:
When a mutation alters a protein that plays a critical role in the body, it can disrupt normal development or cause a medical condition. A condition caused by mutations in one or more genes is called a genetic disorder. In some cases, gene mutations are so severe that they prevent an embryo from surviving until birth.Over time, a mutation might take place in one of the descendant cells, causing increased activity of a positive cell cycle regulator. The mutation might not cause cancer by itself either, but the offspring of this cell would divide even faster, creating a larger pool of cells in which a third mutation could take place.

You have been looking at meiosis beginning with a diploid cell that has the genotype AaSs. The alleles in the haploid gametes produced by meiosis are
Answer:
AS, As, aS, as
Explanation:
Meiosis is the cell division that involves the production of daughter cells or gametes with a reduced number of chromosomes. i.e. diploid (2n) - haploid (n).
According to Gregor Mendel in his law of Segregation, the alleles of a gene will separate into gametes in such a way that only one allele will be present in each sex cell. Hence, in this diploid cell with genotype AaSs, the alleles will separate into the haploid cell in the following genotype proportion:
AS, As, aS, and as
When a patient comes to a hospital with severe dehydration, doctors will give
them an IV filled with a salt-water solution called saline, which is isotonic with
the body's blood cells.
Why is the patient not given pure water?
Answer:
The red blood cells could burst.
Explanation:
If they are given pure water, the IV fluid will be hypotonic to the blood cells. That means water will end the red blood cells by osmosis, from a high concentration outside to a lower concentration inside.
This will result in the red blood cells becoming swollen and even potential bursting.
