Which factor determines carrying capacity?
A. Species diversity
O B. Limiting factors
O C. Population density
O D. Feeding relationships
Answer:
D
Feeding relationship I guess
Answer:limiting factors
Explanation: limiting factors determine carrying capacity. The availability of abiotic factors (such as water, oxygen, and space) and biotic factors (such as food) dictates how many organisms can live in an ecosystem. Carrying capacity is also impacted by the availability of decomposers.

Answer:
C) Natural Selection.
Explanation:
Natural selection shows that the tortoises have different leg features, which is most likely due to their islands having different habitats and difficulties to overcome, so the tortoises that survived over time were the ones best suited to their unique island habitats.
Hope this helps! :) Feel free to give me Brainliest if this helped. Have a good day and good luck on your quiz.
Answer:
the answer is natural selection, because the other two are just examples of features developed during natural selection, so natural selection is correct.
The gene that codes for albumin protein in humans is 25,000 base pairs from the beginning of the protein coding sequence to the end of the protein. However, the mRNA for this protein is only 2100 base pairs long. What could account for the large difference
Answer:
RNA splicing
Explanation:
RNA splicing is the mechanism by which messenger RNA precursors (pre-mRNAs) are processed to generate mature mRNA transcripts in eukaryotic genomes. During RNA splicing, the non-coding regions of the pre-mRNA sequence (i.e., introns) are removed, while coding regions (i.e., exons) are joined together. In consequence, the resulting mature mRNA is shorter than the pre-mRNA. RNA splicing reactions are catalyzed by the spliceosome, an RNA-protein complex that removes introns from the pre-mRNA. After RNA splicing, the mature mRNA is used as template to produce a specific amino acid sequence, where triplets of RNA nucleotides (codons) in the mRNA are used to assemble specific amino acids in order to form a protein.

What is the jet stream, how does it affect us?
Answer:
How Do Jet Streams Affect Weather? The fast-moving air currents in a jet stream can transport weather systems across the United States, affecting temperature and precipitation. However, if a weather system is far away from a jet stream, it might stay in one place, causing heat waves or floods.
What types of mutations can lead to a change in the proteins that are made?
point mutation or frameshift mutation
Answer: either can as long as it is a substantive change to the genetic code and the change of nucleotide changed the code from one protein signature to another
Explanation:
Which of the following statements about an energy pyramid is NOT correct?
Group of answer choices
Only about 10% of energy is passed from one trophic level to the next.
Autotrophs are always located at the bottom of the pyramid.
An energy pyramid shows the same flow of energy as a food chain does, it just stacks the trophic levels on top of each other.
Ecosystems have more energy at higher trophic levels than at lower trophic levels.
Answer:
The answer that would NOT be correct is the last one , (Ecosystems that have more energy at higher trophic levels than at lower trophic levels. )
why is there an increase in heart rate and breathing during exercise
Answer:
the heart must pump more blood to other places of the body
Explanation:
Explanation:
As you exercise energy and oxygen are needed by the muscles to work, therefore the faster you move the quicker your heart beats inorder to supply the muscles you are using with energy and oxygen.

13.) Remnants of organs or bones that have no use now in the organisms but may have for their common ancestors…
A.) Homologous Structures
B.) Embryo
C.) Vestigial Structures
D.) Fossil Record
Answer:
Vestigial structures
Explanation:
Vestigial structures serve little or no purpose for an organism. An example being the human tailbone which at one point might have been a tail, but serves no real purpose now since we're bipedal organisms
Horses have a gene for coat color. The dominant allele gives a brown coat while the recessive allele gives a white coat. A breeder is crossing a purebred brown horse with a hybrid brown horse. What are the possible phenotypes of the offspring?
Answer:
they will all be brown horses but only two will have both dominant alleles, the other two will each have one recessive

Why are viruses to be nonliving
Answer:
Most biologists say no. Viruses are not made out of cells, they can't keep themselves in a stable state, they don't grow, and they can't make their own energy. Even though they definitely replicate and adapt to their environment, viruses are more like androids than real living organisms.
Which stage of the cell cycle occurs after mitosis in which the cell creates a cleavage furrow.
Interphase
G2
Anaphase
Cytokinesis
Answer:
Anaphase
Explanation:
After anaphase, a cleavage furrow forms in the equatorial cortex in typical animal mitosis. To divide the two daughter cells, this furrow then progresses inwards.
The sister chromatids differentiate from each other in anaphase and are pulled toward opposite ends of the cell. The "glue" of protein that binds together the sister chromatids is broken down, causing them to separate. Each one now has a chromosome of its own.

What biotic and abiotic factors of ocean systems are changed when runoff water containing pollutants and fertilizers enter the ecosystem?
Biotic factors include plants, animals, and microbes; important abiotic factors include the amount of sunlight in the ecosystem, the amount of oxygen and nutrients dissolved in the water, proximity to land, depth, and temperature. Sunlight is one the most important abiotic factors for marine ecosystems.

Which of the following best describes the function of the coenzymes NAD and FAD
in eukaryotic cellular respiration?
Answer:
They accept electrons during oxidationreduction
reactions.
In cellular respiration in eukaryotic, reducing power is provided to the electron transport chain by NAD and FAD, so they act as electron acceptors in the process.
What is the function of coenzymes NAD and FAD in eukaryotic cellular respiration?In eukaryotic cellular respiration, they function as the electron transport chain's ultimate electron acceptors.
The cofactors nicotinamide adenine dinucleotide (NAD+) and flavin adenine dinucleotide (FAD+) is important in cellular respiration. They receive "high energy" electrons and convey them to the electron transport chain.
Where they are utilized to manufacture ATP molecules, and is the energy source for all the cellular process in eukaryotic organisms.
Therefore, NAD and FAD is electron acceptor during cellular respiration in eukaryotes.

Number 12
Number 19
Number 16
Answer:
12) When a solid dissolves the solid (solute) and the liquid (solvent) form a very close intimate mixture called a solution
16) In other words, plasma membranes are selectively permeable—they allow some substances through but not others. ... The most direct forms of membrane transport are passive. Passive transport is a naturally occurring phenomenon and does not require the cell to expend energy to accomplish the movement.
19) To move substances against a concentration or electrochemical gradient, the cell must utilize energy in the form of ATP during active transport. Primary active transport, which is directly dependent on ATP, moves ions across a membrane and creates a difference in charge across that membrane.
