List 4 examples of limiting factors described in the reading and label each if it would be considered an abiotic or biotic limiting factor.
Answer:
Explanation:food, water, habitat, and mate.
Limiting factors can be either abiotic or biotic. Examples: Abiotic → water, pH, radiation, salinity. Biotic → predation, competition, parasitism.
What are biotic and abiotic factors?The ecosystem is composed of living and non-living elements that interact and depend on each other. These are the biotic and abiotic factors.
• Abiotic factors are physical and chemical components of the ecosystem. These are the non-living elements.
• Biotic factors are all the living components in the ecosystem.
Biotic and abiotic factors influence the survival and reproduction of living beings.
What are the limiting factors?Limiting factors are environmental conditions that act directly on populations and individuals, limiting their distribution and growth.
These factors might be either biotic or abiotic and affect natality and mortality rate, migration, etcetera.
Limiting factors might be a result of the population density or might be dense-independent.
When talking about dense-independent limiting factors we are referring to
abiotic factors, such as temperature, pH, salinity, humidity, radiation, etcetera.natural disasters like fires, volcanic eruptions, flooding, etceterahuman impactWhen talking about dense-dependent limiting factors we are referring to biotic factors and the interactions established between species that control other species' growth.
These are, for instance,
competition, parasitism, and predation
Each species carries out a different role in these interactions.
These relationships and the results are what determine the destiny of the populations and their size.
Now, since I do not have the text, I will suggest a few examples of limiting factors. Take a look at them and then look for some other examples in your reading.

Explain how the model of the chemical reaction above demonstrates that matter is conserved.
Answer:
Matter cannot be created or destroyed in chemical reactions. This is the law of conservation of mass. In every chemical reaction, the same mass of matter must end up in the products as started in the reactants. Balanced chemical equations show that mass is conserved in chemical reactions

Please help with answer 3 :)
Answer:
1) Diffusion : Is the movement of molecules / ions from a region of higher to lower concentration. It may or may not occur across a semi permeable membrane.
In diffusion there is no challenge involved as it is along the concentration gradient, but in active transport movement of molecules occur against concentration gradient ie; from lower to higher concentration.
2) For active transport, energy is vital for movement, in this case protein molecules function as molecular pumps to enable the cell accumulate glucose/ions, against concentration gradient. Here metabolic energy ATP is required.
3)Facilitated diffusion is a type of passive transport in which ions/molecules cross the semi permeable membrane because permeases present in the membrane facilitate the transport.
Like simple diffusion facilitated diffusion doesn't require metabolic energy and simply occurs across the concentration gradient.
4) Osmosis : is movement of water from hypotonic solution (lower concentration) to hypertonic solution (higher concentration) through a semi permeable membrane.
The cell membrane being permeable to water allows to and fro movement of water molecules along the concentration gradient.

The statements about meiosis that are false include the following:
C. During meiosis II, paired homologous chromosomes move up to the equator of the cell.
G. In meiosis II, ploidy is reduced.
H. During anaphase I, sister chromatids separate.
Meiosis can be defined as a type of cell division or duplication that occurs in all body cells found in living organisms, through which a single cell divides twice to produce four (4) haploid cells (gamete).
During cell division, deoxyribonucleic acid (DNA) must be replicated before meiosis can take place in any body cell found in living organisms.
Generally, the phases or steps that occur during meiosis include:
Prophase I.Metaphase I.Anaphase I.Telophase I.Prophase II.Metaphase II.Anaphase II.Telophase II.Furthermore, the statements about meiosis that are false include the following:
1. During meiosis II, paired homologous chromosomes move up to the equator of the cell.
The movement of paired homologous chromosomes to the equator of the cell takes place during prophase II.2. In meiosis II, ploidy is reduced.

can solute particles pass through the membrane of a semipermeable membrane?
Answer:
No.
Explanation:
No, solute molecules are larger in comparison to solvents, so they cannot pass through the semi-permeable membrane.
Answer:
Nope Nope Nope, They cannot pass through it
Explanation:
Osmosis describes the diffusion of the solvent through a semipermeable membrane. The driving force of the solvent shift is the concentration difference of solutes in the solutions separated by the semipermeable membrane. In contrast to solvent, solutes cannot pass this barrier.
A change in pH has the greatest impact on which life proces
Answer:
Aquatic Organisms
If the pH of water is too high or too low, the aquatic organisms living within it will die. pH can also affect the solubility and toxicity of chemicals and heavy metals in the water ¹². The majority of aquatic creatures prefer a pH range of 6.5-9.0, though some can live in water with pH levels outside of this range.
Explanation:
Adding more OH- ions increases the pH, making the substance more basic. Increasing the pH will increase the number of OH- ions, so the equilibrium will shift to the left. Decreasing the pH will increase the number of H3 O+ ions; they'll ''use up'' the OH- ions, thus shifting the equilibrium to the right.

All of the following occur during RNA processing EXCEPT______________A) a protective cap is added on the 5' end of the pre-mRNAB) a tail of many adenine nucleotides is added to the 3' end of the mRNAC) the exons and introns are both removed from RNA
During RNA processing, a protective cap is added to the 5' end of the pre-mRNA, a tail of many adenine nucleotides is added to the 3' end, and only introns are removed. The correct option is C.
The pre-mRNA synthesized during transcription undergoes some processing before being ready for translation. The first thing is the addition of a protective cap to the 5' end and the modification of the 3' end by the addition of a long string of adenine nucleotides.
Thereafter, the pre-mRNA is spliced to remove non-coding sequences, also known as introns. The coding sequences (exons) are joined afterwards before the mRNA is ready to be translated.

ribozymes are rna molecules that have enzymatic activity. this conflicts with the belief of early molecular biologists that
Ribozymes conflict with the belief of early molecular biologists that each enzyme is a polypeptide. A ribozyme is composed of RNA.
A ribozyme (ribonucleic acid enzyme) is an RNA molecule capable of speeding up a chemical reaction.
In consequence, ribozymes have catalytic activity.
For example, within the ribosome, the large subunit of ribosomal RNA acts as a ribozyme that links amino acids during the synthesis of polypeptide chains.
On the other hand, enzymes are specific proteins (composed of amino acids) that can speed up chemical reactions.

One of the most common plants in Atlantic salt marshes is cordgrass. periwinkle snails cling to the top of tall cord grass is during high tide. The tall cord grass is provide protection from the snails predators such as blue crab. well the snails do not be directly on cordgrass the snails can damage the cord grass when they grays and algae and fungi that grow on the grasses. if the snail populations grow too large they can decrease cord grass growth.
Cordgrass is a biotic factor for the snails because it is a living source of protection in the Atlantic salt marshes for the snails. Hence option B is correct.
Biotic factors - The living components or the living things that are present in the ecosystem that shapes the environment are known as biotic factors. Examples are plants, bacteria, algae, birds, fishes etc.
A ecosystem runs through the interaction of biotic and abiotic component. Biotic supplements acts as a fuel that supports the bacterial growth.
Periwinkle snails graze on the top of the cordgrasses to escape from their predators blue crab. They graze on the fungi and algae that is inhabitant on top of the grass, they do not feed directly on the cordgrass
While grazing they actually damage the cordgrass by spreading the fungal infection.
