The characteristics of allosteric enzymes are regulatory molecules can bind and modify the catalytic activity of these enzymes.
What are the main characteristics of enzymes?Enzymes are proteins that catalyze chemical reactions that occur in living things. They speed up the speed of reactions, which contributes to metabolism. Without enzymes, many reactions would be extremely slow. During the reaction, the enzymes do not change their composition and are not consumed either.
In this case, Allosteric enzymes are enzymes that contain a region separate from the substrate to which small regulatory molecules can bind and modify the catalytic activity of these enzymes.

A camel has a hump to store water so it can survive in its desert environment. Which kind of adaptation is this?
A camel’s hump is an example of
adaptation.
Answer:
Camels actually store FAT and not water in their hump. This is called structural adaption.
Explanation:
Camels’ unique physiology and adaptations allow them to survive, even in the harshest conditions of the desert. Camels have thick fur to protect them from the heat, fat hump to serve as food storage, they rarely sweat, and can go for weeks without water. These are only a few reasons how camels survive in the desert, even without water.

Which best summarizes the flow of energy in a producer?
O Sun > ADP > muscle cells
O Sun > mitochondria > CoH1206
O Sun > chloroplasts > mitochondria
O Sun > mitochondria > chloroplasts
The correct answer to the given question is O Sun > chloroplasts > mitochondria ie. Option (C)
Chemical reactions are how energy moves through living things. One set of substances, known as reactants, are transformed into another set, known as products, during each chemical reaction.Such reactions take place in plants as a result of the sunlight-to-chemical energy conversion process, which powers plant growth and other operations.In particular structures known as chloroplasts, this process, referred to as photosynthesis, involves the combination of carbon dioxide and simple sugars to create more complex carbohydrates. The cells of plants, algae, and some protists include these membrane-bound organelles called chloroplasts.From one atom or molecule to another, electrons move. The relevance of these oxidation-reduction (or redox) reactions in mitochondria to living systems cannot be overstated.In this manner, molecules that carry energy are created and put to use for efficient energy transfer
Hence, the correct answer is O Sun > chloroplasts > mitochondria ie. Option (C)

Which correctly describes crossing over?
the process whereby non-sister chromatids exchange genetic material
the process whereby homologous chromosomes are pulled to opposite poles of the cell
the process whereby sister chromatids are pulled to opposite poles of the cell
the process whereby homologous chromosome pairs align randomly along the metaphase plate
The correct option is A ie the process whereby non-sister chromatids exchange genetic material
Between prophase I and metaphase I, a process known as crossing over occurs in which two homologous non-sister chromatids join up and exchange various pieces of genetic material to create two recombinant chromosome sister chromatids.When genetic material is switched between two chromosomes, this process is known as crossing over.It is in charge of causing genetic variation among members of a species.Only the reproductive cells known as gametes undergo this process.The steps involved in crossing over are as follows:1) Synapsis.

have their own DNA but no
organelles.
Mitochondria and chloroplasts are MOST SIMILAR to which type of cell?
A. root cells
b amoeboid cells
C. prokaryotic cells
Answer:
C. prokaryotic cells
Definitions
The Mitochondrion is an organelle in the cytoplasm of cells that functions in energy production.
Chloroplast is usually defined as a plastic containing chlorophyll.
Chlorophyll is the green coloring matter of leaves and plants, essential to the production in a bluish-black form, C55H72MgN405 (chlorophyll a), and a dark-green form, C55H70MgN4O6 (chlorophyll b).
A root cell is one of the maestro cells in the human organic structure that has possible ability of turning into any of the more than the organic structure's 200 cell types.
Prokaryotes is any cellular organism that has no nuclear membrane, no organelles in the cytoplasm except ribosomes, and has its genetic material in the form of single continuous strands forming coils or loops, characteristic of all organisms in the kingdom Monera, as the bacteria and blue-green algae.
What are the similarities and differences between prokaryotes, mitochondria, and chloroplasts?Both mitochondria and heterotrophic prokaryotes, as well as chloroplasts and autotrophic prokaryotes, have a genetic structure (DNA with a circular double helix shape and the genes themselves), as well as comparable ribosome types. In reality, the endosymbiotic idea is based on these parallels.

summary of what occurs during transcription
The act of copying information from a strand of DNA into a fresh messenger RNA molecule is called transcription (mRNA).
DNA preserves genetic material as a reference or template safely and permanently in the cell nuclei.
The process of gene expression starts with transcription. A gene's DNA sequence gets transcribed into RNA during this process. The DNA double helix must unwind close to the gene being transcribed before transcription can begin. A transcription bubble is the term for the area of opened-up DNA.
