Answer:
It is a gel-like matrix composed of water, enzymes, nutrients, wastes, and gases and contains cell structures such as ribosomes, a chromosome, and plasmids. The cell envelope encases the cytoplasm and all its components. Unlike the eukaryotic (true) cells, bacteria do not have a membrane enclosed nucleus.
Explanation:
Flagella, cell wall, and pili are parts of a bacterial cell.
What is a bacterial cell?Microscopically small, single-celled creatures known as bacteria are found in millions in every habitat, both within and outside of other living things.
Some bacteria are hazardous, but most serve a helpful role. They are employed in industrial and medical procedures and sustain a wide variety of living forms, including both plant and animal life.
Around 4 billion years ago, bacteria are assumed to be the initial lifeforms to emerge on the planet. The earliest fossilized creatures are bacteria-like ones. Most biological and some materials can be used as food by bacteria, and certain strains can withstand harsh environments.
New insights into the functions of the gut microbiome are being provided by this expanding interest in how microorganisms affect human health. Bacteria are prokaryotes that do not contain any membrane-bound organelles.
Therefore, flagella, cell wall, and pili are parts of the bacterial cell.

what do the three major checkpoints for cell division have in common?
Answer:
There are three major checkpoints in the cell cycle: one near the end of G1, a second at the G2/M transition, and the third during metaphase. Positive regulator molecules allow the cell cycle to advance to the next stage. ... Each successive cell division will give rise to daughter cells with even more accumulated damage.

what is the species that is most distinct through the largest number of genetic differences or the most different morphologically, compared to other species of interest, called?
An outgroup is a distantly related group of animals used to determine the evolutionary relationships of the ingroup.
What are outgroup species?An outgroup, which differs from sociological outgroups, is a group of organisms that are more distantly connected and that is used as a reference group when assessing the evolutionary relationships of the ingroup, the group of organisms that are the subject of the study.
Looking at a closely related species that is known to be phylogenetically distinct from the group of species we are researching is known as the "outgroup comparison" strategy. It is likely that the character state in that outgroup was ancestral to the group under study.
Examples are Gibbons, Marsupials, Echinoderms, and Gymnosperms.

what is a chain of molecules linked with peptide bonds
Answer:
polypeptide chain
Explanation:
each amino acid unit in a polypeptide is called a residue. A polypeptide chain has polarity because its ends are different, with an α-amino group at one end and an α-carboxyl group at the other.
A chain of molecules connected by peptide bonds forms a polypeptide, a fundamental component of proteins. Peptide bonds are chemical bonds that link amino acids, the building blocks of proteins. This chain structure determines a protein's shape and function.
A polypeptide is made up of a series of molecules connected by peptide bonds and is an essential component of proteins. The coupling of amino acids is made easier by peptide bonds, which are produced by a condensation reaction between the carboxyl group of one amino acid and the amino group of another.
These amino acids, which are the building blocks of proteins, each have a distinct side chain, or R-group, which influences their characteristics. A polypeptide chain's amino acid composition determines the protein's three-dimensional shape, which is essential to its function. This complex link between structure and function emphasizes the importance of peptide bonds in biological processes.

10. Explain how both a population of moose and wolves in the same area could each affect the
size and distribution of the plant population in a community:
Answer:
Since moose are herbivores, they could cause a plant population to decrease in size.
Since wolves are carnivores and hunt moose, there would be less moose feasting on plants, so the plant population would be allowed time to grow back larger.
Depending on how many wolves there are to moose, the plant population will tend to vary.
For example: If the moose population is greater than the wolf population, there will be a smaller population of plants. On the other hand, if the wolf population is greater than the moose population, there will be a greater population of plants.

Amino acids form peptide bonds through dehydration. Explain the role of water in this process by describing the chemical reaction.
Answer:
A peptide bond is a chemical bond formed between two molecules when the carboxyl group of one molecule reacts with the amino group of the other molecule, releasing a molecule of water (H2O). This is a dehydration synthesis reaction (also known as a condensation reaction), and usually occurs between amino acids.
Explanation:
Peptide bonds are- Any reaction that combines two monomers in a reaction that generates H2O as one of the products is known as a dehydration reaction, so peptide bond formation is an example of a dehydration reaction.

4. Some early mornings , dew drops can be found on grass or a car parked outside,
but not on other materials such as the sidewalk. Why is that?
the nighttime temperature on grass and the car went below the dew point, but
the temperature of the concrete did not drop enough to reach the dew point
level
temperature on the grass and sidewalk were both above the dew point levels all
night
the relative humidity of the air above the grass was higher than it was above the
concrete
none of the above
Dew drops can be found on grass or a car parked outside but not on other materials such as the sidewalk because; The nighttime temperature on grass and the car went below the dew point, but the temperature of the concrete did not drop enough to reach the dew point level.
Definition:
The dew point is simply defined as the temperature below which the water vapour in a given volume of air at a constant pressure will condense into liquid water. More specifically, the dew point is the temperature at which the air is saturated with moisture.From the definition above, it is evident that the fact that the nighttime temperature on grass and the car went lower than the dew point temperature is responsible for the condensation of water vapour on grass and the car as opposed to the case in Concrete.
