What are the Biotic factors?The dwelling additives of the surroundings are called biotic elements. Biotic factors encompass plant life, animals, and micro-organisms. The non-living additives of the surroundings are called abiotic elements.
Thses are organisms that can't put together their very own food and rely upon plant life and animals for meals. Depending on how they attain meals, there are 4 forms of consumers: primary, secondary, tertiary and quaternary consumers.

Which DNA-containing central cell structure found in plant and animal cells is absent in bacterial cells?
The DNA-containing central cell structure found in plant and animal cells is absent in bacterial cells is nucleus.
What is nucleus?The part of a cell that houses the chromosomes in biology. The membrane-enclosed nucleus is where RNA is synthesised from the chromosomal DNA.
DNA is organised into chromosomes in the nucleus, which is located in the centre of the cell.
The double nuclear membrane (outer and inner) that separates the nucleus from the cytoplasm, known as the nuclear envelope, envelops it. The rough endoplasmic reticulum and the outer membrane are one unit.
The nucleolus' main job is to facilitate ribosome biogenesis by assembling and digesting rRNA into preribosomal particles.
Bacterial cells lack the nucleus, the primary cell structure that houses DNA, that is present in plant and animal cells.
Thus, nucleus is only present is eukaryotic cells.

Explain why an area with extreme temperatures like one in the Arctic would be resistant to invasion by a biotic disturbance.
Answer:
Negative responses protect our body by taking the deviation and making it less harmful to the body. When you cut your finger and lose blood, negative feedback kicks in to slow and stop the flow of blood.
The reason of area having high temperatures should be because of the negative response.
Reason of area with extreme temperatures:Due to the negative response, it protect our body by considering the deviation and it make less harmful to our body.

The red shift of light from most galaxies is evidence that
Answer: This means that the further away the galaxies are, the faster they are moving. ... Red-shift data provides evidence that the Universe, including space itself, is expanding. Redshift and blueshift describe how light shifts toward shorter or longer wavelengths as objects in space (such as stars or galaxies) move closer or farther away from us. ... When an object moves away from us, the light is shifted to the red end of the spectrum, as its wavelengths get longer.

Put the following events of eukaryotic translation in chronological order:
1. Binding of mRNA and ribosome at the mRNA start codon
2. Stop codon releases the ribosome and translation stops
3. Complementary base pairing between initiator codon and anticodon of initiator tRNA
4. Peptide bond formation between amino acids
5. Release of Finished protein product
Answer:
1, 3, 4, 2, 5
Hope it helps!
Proteins translation occurs in the cytosol. It involves the association of mRNA to the ribosome and to tRNA. The codons determine the amino acids sequence. The order is 1, 3, 4, 2, 5.
------------------------------
Protein synthesis involves transcription -which occurs in the nucleus-, and translation -which occurs in the cytosol-.
Once in the cytoplasm mRNA meets a free ribosome, the primary structure for protein synthesis. Ribosomes might be floating freely in the cytoplasm or attached to the rough endoplasmic reticulum.mRNA and ribosomes also associate with different tRNA that carries amino acids.The ribosome recognizes the start codon in the mRNA and starts reading the strain in a 5´ to 3´ direction. According to the codons being readen, tRNA transfers the correct amino acids to build the polypeptide chain.
Each tRNA has two important sites. One of them is the antidocon that couples with the codon of the mRNA molecule. The other site couples with the coded amino acid.
The new amino acid joins the growing chain through peptidic bonds between the carboxyl and amino groups. The tRNA leaves the ribosome and sets free to join another amino acid and repeat the cycle.
The protein is synthesized from the amino terminus to the carboxy terminus, while the added amino acids to the chain are coded by a codon formed by three bases in the mRNA.
When the ribosome meets the stop codon, protein synthesis finishes. The polypeptide is released.
The correct order of steps is
1. Binding of mRNA and ribosome at the mRNA start codon
3. Complementary base pairing between initiator codon and anticodon of initiator tRNA
4. Peptide bond formation between amino acids
2. Stop codon releases the ribosome and translation stops
5. Release of Finished protein product

Answer:
These metamorphosis examples are of both insects and amphibians -- the only creatures that go through this process. Amphibians are the only animals with a backbone that can do it.
Answer:
the frog and the ladybug go through a metamorphosis. The ladybug larva looks like a completely different insect from its final adult form. The frog goes through a tadpole stage in which it lives underwater, and then develops into a frog that can live on land.
Explanation:
In a mangrove swamp, mangrove tree crabs consume the leaves of mangroves and are food for other animals. By eating decaying mangrove leaves, animal wastes, and dead animals, they help create detritus that forms the base of many of the swamp's aquatic food chains. In addition, they burrow in the wet soil, which mixes air containing oxygen with the soil. What is likely to happen to the stability of the community if a disease destroys the population of mangrove tree crabs? (1 point) Think about how a community adjusts when one species is negatively affected.
The stability of the community if a disease destroys the population of mangrove tree crabs will be reduced.
What is a Community?This is referred to as a place where organisms who share certain characteristics live and interact.

Ecologists study both biotic and abiotic factors and how they interact. Therefore, ecologists often use methods and data from other areas of science, such as geology, geography, climatology, chemistry, and physics.
Abiotic factors refer to non-living physical and chemical elements in the ecosystem. Abiotic resources are usually obtained from the lithosphere, atmosphere, and hydrosphere. Examples of abiotic factors are water, air, soil, sunlight, and minerals

How can you study biotic and abiotic factors within an ecosystem?The interactions between biotic factors, such as organisms like flora and fauna, and abiotic factors.
For example, all animals (biotic factors) breathe in oxygen (abiotic factor). All plants (biotic factor) absorb carbon dioxide (abiotic factor) and need water (abiotic factor) to survive.

All of the major components of the light reactions, including the pigment molecules
clustered in photosystems I and II, are located in the thylakoid membrane. What is the advantage of
having these components confined to the same membrane rather than dissolved in the stroma or the
cytosol/cytoplasm? Explain your argument. (up to 5 points)
Answer:
Having the light reaction components in close proximity speeds up the process. Electrons move from one protein to the next in sequence. If the proteins had to 'swim' around to find the next part of the electron transport chain, then the ATP would form at a much slower, inefficient rate.
