Answer:
Bacteria cells have no membrane bound organelles.Bacteria cells are prokaryotic.Bacteria cells have cell walls.Bacteria cells have strong flexible layers surrounding their cell membranes.Bacteria are called prokaryotes; they lack a nucleus and do not present organelles in the cytoplasm, their observable characteristics are:
The nuclear region of bacteria is not surrounded by a membrane, and consists simply of a single circular double-stranded DNA molecule, which constitutes the bacterium's chromosome (genome).The bacterial cell wall is composed of a macromolecular network called peptidoglycan or murein.The cell wall that gives them their shape and provides mechanical protection, since bacteria are found in environments that can have different concentrations of solute.
Glycocalyx is the polysaccharide-containing structure located on the outer side of the bacterial cell wall.Some bacteria produce flagella, these are long, thin appendages that serve as locomotion organelles.Axial filament a series of fibrils that arise at the ends of the cell below the outer sheath and follow a helical path around the cell.The fibria are structures that enable bacteria to adhere to inert surfaces or to form films on the surface of liquids.Therefore, we can conclude that bacteria are microorganisms that contain structures required for their growth and self-replication, without them these microorganisms lose their integrity.

"A testcross involves an individual exhibiting the dominant phenotype but an unknown genotype being crossed with an individual that has a(n) ___________ genotype."
Answer:
The correct answer is - h(omo)zygous recessive
Explanation:
When a cross between the organism with dominant phenotype, that can be heterozygous genotype or h(omo)zygous genotype, with a organism of h(omo)zygous recessive takes place, the cross known as test cross.
Test cross always exhibit an individual with the dominant phenotype. he aim of test cross is to find if the dominant individual is h(omo)zygous or heterozygous.
Thus, the correct answer is - h(omo)zygous recessive.
Amino acids and sugars are both required by animals to maintain their health. Without a diet
containing both of these, animals cannot survive. Amino acids are obtained by animals when
they digest -
A carbohydrates
B proteins
C nucleic acids
D lipids
Answer:
Proteins..............
Amino acids are obtained by animals when the person digest proteins. The correct option is B.
What are proteins?A protein is a found naturally, a highly complicated substance made up of amino acid residues linked together by peptide bonds.
Proteins are found in all living organisms and contain a variety of important biologically active compounds such as enzymatic reactions, hormones, and immunoglobulin.
Proteins are massive complex molecules that perform numerous important functions in the body.
They are essential for the structure, operation, and regulatory oversight of the body's tissues and organs and do the majority of the work in cells.
Protein can be found in muscle, bone, skin, hair, and virtually every other body part or tissue.
It is the building block of enzymes, which power many chemical reactions, as well as hemoglobin, which transports oxygen in your blood.
Thus, the correct option is B.

Which of the following is an example of an enzyme?
Carbohydrates
O Proteins
O Lipids
O Nucleic acids
Answer -proteins
Any of a set of enzymes that divide proteins into shorter pieces (peptides), and subsequently into their constituent amino acids, is known as a proteolytic enzyme. Thus, option B is correct.
What is role of enzymes as a protein?Enzymes are proteins that interact with substrate molecules to stabilize the transition state and lower the activation energy required for a chemical reaction to occur.
Through stability, reaction rates accelerate and reach physiologically important rates.
Proteins called enzymes are made up of amino acids connected by one or more polypeptide chains.
The fundamental structure of a polypeptide chain refers to this arrangement of amino acids. The three-dimensional structure of the enzyme, including the geometry of the active site, is then determined by this.
Therefore, Proteins are an example of an enzyme.

Answer:
what is the question asking? like a true or false?
Explanation:
What's the independent variable? What's the dependent variable? How many bacteria were found at 30 degrees? How many bacteria were found at 15 degrees? How many more bacteria were found at 20 degrees than 10 degrees? How many more bacteria were found at 35 degrees than 0 degrees?
Answer: Temperature is the independent variable. The number of bacteria is the dependent variable.
Explanation:
The dependent and independent variables are the two main variables of any experiment or research.
A dependent variable is one whose values depend on another variable. In a function it is usually represented by 'y'. This variable 'y' is a function of the variable 'x', which is the independent variable. An independent variable is one whose value does not depend on that of another variable.
So, the independent variable is the one that changes or is controlled to study its effects on the dependent variable. The dependent is the variable that is investigated and measured.
The independent variable is represented on the x-axis (horizontal line) of a graph, while the dependent variable is represented on the y-axis (vertical line).
In your example, the temperature is the independent variable, because it does not depend on anything and its influence can affect the number of bacteria. And it can be changed or controlled by the scientists. The number of bacteria is the dependent variable, because it depends on the temperature. Also, the number of bacteria is what it is being measured, and can not be changed by the scientists.
What is the conclusion of careful studies regarding the relationship between environmental policies, on the one hand, and jobs and the economy, on the other?
Answer:
There is a positive relationship between environmental policies and jobs and the economy.
Explanation:
The conclusion of the studies is that environmental policies increase employment in the industrial sector. It is because for reducing pollution, the industries does not use heavy machinery for increasing production so these industries uses labour to maintain its production capacity and for more production more labour is required which decrease the problem of unemployment while economy also increases due to more production of products in the industries.

and seeks equilibrium, including atoms and molecules?
Answer:
yes i do know its up top on the notch
Explanation:
do you think all living organisms have the same types of cells why or why not
All organisms do not have the same number and type of cells because each one has different characteristics.
On Earth there are different types of organisms, some are complex like plants or animals, these are multicellular because they have a large number of cells.
However, all organisms are not the same. Some are characterized by having only one cell such as bacteria or algae.
On the other hand, not all organisms have the same type of cell. Some have prokaryotic cells, that is, cells that do not have a defined nucleus. Some examples of an organism with prokaryotic cells are:

A student wants to create a liquid volcano. The student observes bubbles in the soft drink prior to opening it. The student first proceeds to open the soft drink bottle and place it on the floor. Next the student drops candy tablets into the drink using a rolled piece of paper, so that the tablets are able to fall into the drink continuously. The student notices a very powerful reaction as the drink fizzes and starts to bubble.
In this scenario, what would be the catalyst?
1.)
2.)The candy tablets being added to the drink. The gasses being released when the drink was first opened.
3.)The piece of paper being placed over the soft drink. The container that holds the liquid.
