Answer:
all functions
Explanation:
To survive, unicellular cells must carry out all functions.
Hope this helps!
Unicellular cells must carry out all functions of life. Thus, the correct option is A.
What are Unicellular cells?Unicellular cells may be defined as those organisms that generally consist of only a single cell. This single cell carries all the essential functions of life which are required in order to survive in nature.
The complexity of the genome in a such single-celled organism is very simple. The mechanism of compartmentalization is not found inside the cell of such organisms. All the functions are carried out by the same cell.
Examples of unicellular organisms are Bacteria, amoeba, Paramecium, archaea, protozoa, unicellular algae, and unicellular fungi. They possess a cell wall made up of peptidoglycan, chitin, or other forms of polysaccharides. This protect the inner content of the cell.
Therefore, unicellular cells must carry out all functions of life. Thus, the correct option is A.

Meningitis is a result of pathogenic gram-negative bacteria that cause extreme infections when their bacterial cell wall dies and lipopolysaccharide (a lipid and polysaccharide) is released. The lipopolysaccharide is an example of a/an
Answer: ENDOTOXIN
Explanation: Meningitis is a nervous system disorder that occurs when there is an infection and inflammation of the meninges,these meninges are the membranes that cover the brain and the spinal cord,they are the pia mater, dura mater,and the arachnoid mater.
This infection and inflammation of the meninges is causes by inversion of microorganism, bacteria precisely,when these bacteria that are gram negative invade the meninges,the cell wall of the bacteria dies off exposing the cellular contents, this exposure introduces a toxin known as LIPOPOLYSACCHARIDE directly in to the meninges which disrupts the normal functioning of the meninges, infection further sets in and inflammation is triggered as well.
Consider an experiment in which starch is dissolved in a liter of water. Some of the solution is placed into a securely tied dialysis bag. The dialysis bag is placed into a beaker containing distilled water and iodine for 30 minutes. What are the correct answers for the questions below? (Note: Iodine reacts with starch to create a black/purple color.) What would happen to the color of the solution in the bag? a. The solution in the bag would turn purple as the iodine reacts with the starch. b. The solution in the bag would grow lighter as the starch leaves the bag and enters distilled water and iodine.
Answer:
a. The solution in the bag would turn purple as the iodine reacts with the starch.
Explanation:
According to this question, a solution containing starch is placed into a securely tied dialysis bag. The dialysis bag is then placed into a breaker containing distilled water and iodine for 30mins.
The starch is a solute substance, which when added to the solution in the dialysis bag makes the solution in the bag HYPERTONIC in comparison to the hypotonic (low solute concentration) distilled water+iodine in the beaker. Based on this concentration gradient (difference in concentration), osmotic flow will occur across the dialysis bag (semi-permeable membrane).
Note that, osmosis is the movement of water from a region of low solute concentration to a region of high solute concentration across a membrane. Hence, water+iodine from the breaker will move into the solution in the dialysis bag.
Because the solution entering the dialysis bag contain iodine, it will react with the starch content of the dialysis bag and form a dark purple coloration inside the dialysis bag.

difference between paw paw and tomato
Answer:
❥ Ripe pawpaws give off a wonderful fruity aroma. If the pawpaw does change color, it will likely turn a lighter shade of green, possibly with some yellowing. A more reliable indicator is feeling. The fruit will begin to feel softer, much as a peach or avocado.
❥ Your ripe tomato will give slightly to the touch. It shouldn't be soft but rather a little tender. Because tomatoes ripen from the inside out, this is a good indicator that it's ready.

How do mitosis and meiosis differ among humans, chickens, and alligators?
Answer:
Mitosis- produce two identical somatic daughter cells
Meiosis- produce four genetically different reproductive daughter cells.
Explanation:
Mitosis and meiosis are the two major cellular divisions in multicellular organisms. However, they differ in series of aspects.
Mitosis is a cell division that involves the production of two daughter cells which are genetically identical to the parent cell. Mitosis is used to multiply somatic cells, hence, it is called multiplication division. Mitotic process is the same in humans, alligators and chickens.
Meiosis, contrarily, is a cell division that involves the production of four daughter cells which are genetically different from the parent cell. Meiosis occurs in a two step division process in order to produce sex cells or gametes with a reduced number of chromosomes. Hence, meiosis is called reduction division. Note that, meiosis only occurs in reproductive cells. Meiotic process is likewise in humans, alligators and chickens as long as they reproduce sexually via gametes.
Mitosis and meiosis differ among humans, chickens and alligators because of their different functions and the presence of chromosomes.
Cell DivisionMitosis and meiosis have two kinds of cell division.
In humans, mitosis is a single cell that splits into two exact daughter cells.
Meiosis creates egg and sperm cells.
In animals, meiosis creates gametes directly, and mitosis happens in somatic cells.
Meiosis in the chicken embryo is formed late in embryogenesis. Meiotic germ cells are rather noticeable only in female gonads.

What makes up genes? Explain in 1 paragraph please
Answer: Genes are made up of DNA
Explanation: Genes are made up of DNA . to be more precise each gene is made out of possibly 25 000 dna to 2 million dna.
A gene is the basic physical and functional unit of heredity. Genes are made up of DNA. Some genes act as instructions to make molecules called proteins. However, many genes do not code for proteins. In humans, genes vary in size from a few hundred DNA bases to more than 2 million bases. The Human Genome Project estimated that humans have between 20,000 and 25,000 genes.
Every person has two copies of each gene, one inherited from each parent. Most genes are the same in all people, but a small number of genes (less than 1 percent of the total) are slightly different between people. Alleles are forms of the same gene with small differences in their sequence of DNA bases. These small differences contribute to each person’s unique physical features.

In comparing stop-transfer and internal start-transfer sequences in proteins, it can be said that __________. In comparing stop-transfer and internal start-transfer sequences in proteins, it can be said that __________. both cause the formation or stabilization of the translocon both cause the disassembly or destabilization of the translocon both are hydrophobic both lead to integral membrane proteins with the same orientation of C and N termini
Answer:
Both are hydrophobic
Explanation:
Because first of all Internal start- transfer process is a process where a peptide is transfered to the side opening of translocon and then then fixes itself in the membrane, whereas
Stop-transfer sequences in proteins act to stop this process of translocation and moves out through the side opening in translocation to fix itself on a membrane this is consistent with the hydrophobic nature that repels water. Because they are non polar and lack the capacity to form a hydrogen bond with another molecule
A refrigerator thermometer is read ten times and registers degrees Celsius as:

temperature inside the refrigerator is 37 degrees C. Is this an example of
precision, accurate, neither, both or neither, Make a selection and explain.
Answer:
Precise, but not accurate
Explanation:
First, let’s define accuracy and precision.
Accuracy: how close you are to the actual value
Precision: how close the measurements are to each other.
Let’s examine the data given:
39.1, 39.4, 39.1, 39.2, 39.1, 39.2, 39.1, 39.1, 39.4, 39.1
Each number is very close to 39, within 0.1 to 0.4.
The actual temperature of the refrigerator is 37 degrees. Each measurement is about 2 away from 37.
Since the measurements are close to each other, but far from the true value, we can say this is precise but not accurate.
