It is located outside the cell membrane and provide cells with structural support and protection all but one type of organism have cells with cell walls. what is it?
Answer: Animals.
Explanation:
Animals are the type of organisms that have cells without any cell wall.
Cell walls are found in plant cells that contain the cell in them, maintaining their shape and preventing them from any sort of damage. But its main purpose is basically to provide support to the plant structure to stand upright.
While animals have bones so they do not need any cell walls in their cells to support their structure.
The one type of organisms which don't have cell wall are animals.
Explanation:As the cell wall is a tough and rigid but flexible structure.Its main purpose is to give support and structure to plant cell, consequently whole plant.In plant cell there is a large vacuole which is filled with water,it also gives shape to plant cell.But animal cells don't need any support.Because the function of support or structure for animal cells is of bones.That is why animals cells lack cell wall.Based on this information, what type of transport is used for glucose in blood and intestinal cells?
What type of transport is involved in this process?
Glucose is transported across the apical plasma membrane (from the lumen inside the cell) of the intestine via the sodium-glucose cotransporter (Na/glucose cotransporter)- The gradient of the Na is established by the Na+/K+-ATPase. This means that the absorption of the glucose is secondary active transport. Glucose is then transported into the extracellular fluid via the glucose transporter and that is the process of facilitated diffusion (passive process, since glucose flows down its concentration gradient).
Glucose is transported in blood and intestinal cells through active transport, specifically secondary active transport or co-transport. This is an energy-requiring process where glucose is moved from low to high concentration.
Explanation:The transport of glucose in blood and intestinal cells is accomplished through a process known as active transport. In this process, carrier proteins in the cell membrane move glucose, against its concentration gradient, from an area of low concentration (outside of the cell) to an area of high concentration (inside the cell). The process requires energy in the form of ATP (adenosine triphosphate).
This is done through a specific type of active transport known as secondary active transport or co-transport, whereby glucose is transported into cells along with sodium ions.

a heart is to _____ muscle as the stomach is to _____.
A tendon; ligament
B involuntary; ligament
C skeletal; smooth
D cardiac; smooth
Cardiac muscle also known as heart muscle is one of three kinds of vertebrate muscles. It is a striated and an involuntary muscle, which forms the prime tissue of the walls of the heart. The cardiac muscles help in contraction of heart to pump blood.
On the other hand, the smooth muscle is found inside the walls of the internal organs and the compositions like the stomach. The stomach has three layers of smooth muscles, that is, the outer longitudinal, the middle circular, and the inner oblique muscles.
Therefore, the heart is to cardiac muscles, and the stomach is to smooth muscles.
The dimensions of your living room are 11ft by 15ft. How many square meters of carpet(area) do you need to buy? (conversion meter factor: 1meter=3.28ft)
first convert the ft into meters so
11ft = 3.35m
15ft = 4.6m
3.35m x 4.6m = 15.41
15.41m^2
15.33 square meters.
Explanation:first calculate the area of the room in square feet by multiplying the length and the width. 11ft times 15ft gives us 165 sq ft.
Now, we need to convert this area into square meters. Given that 1 meter equals 3.28 feet, we square this conversion factor to get the conversion factor for square meters, which is 1 sq meter = 10.76 sq ft.
Finally, divide the area in square feet (165 sq ft) by the conversion factor (10.76). Therefore, you need about 15.33 square meters of carpet.

Name the tripeptide above using the three letter amino acid abbreviations separated by a hyphen (for example: gly-ala-phe).
The specific tripeptide wasn't provided but an example tripeptide consisting of glycine, alanine, and phenylalanine would be named gly-ala-phe. A peptide bond is a chemical bond between amino acids, forming dipeptides, tripeptides and so forth.
Explanation:The question doesn't provide a specific tripeptide sequence to name. However, if we were given a hypothetical example, let's say the tripeptide consisted of glycine, alanine, and phenylalanine, then according to the three-letter amino acid abbreviation, it would be named as gly-ala-phe.
As detailed, the structure of a tripeptide involves three amino acids chemically bonded together by the reaction of the carboxylic acid group of one molecule with the amine group of another, forming what is called a peptide bond.

The name of a tripeptide depends on constituent amino acids, named from the N-terminal (start) to the C-terminal (end) using their three-letter abbreviations. For example, a tripeptide composed of Valine, Leucine, and Serine will be named 'Val-Leu-Ser'.
Explanation:The question didn't provide a specific tripeptide to name, but based on the information given, here's how you would approach this. Amino acids in a peptide are named from the N-terminal (start of the peptide, free amino group) to the C-terminal (end of the peptide, free carboxyl group). Each amino acid is known by its three-letter abbreviation, for example, 'gly' for glycine, 'ala' for alanine, and 'phe' for phenylalanine.
Therefore, if you had a tripeptide made up of, for instance, valine (Val), leucine (Leu), and serine (Ser), you would name it 'Val-Leu-Ser'. This essentially involves naming each amino acid in the order they appear in the tripeptide chain.
It's also important to remember that when naming a peptide, the N-terminal amino acid comes first. So in our example, Valine is the N-terminal amino acid, and serine is the C-terminal amino acid.

Choose all the intermolecular interactions that could occur in a container of only methyl benzoate.
The correct answer is dipole-dipole interactions and London dispersion forces (induced dipole-dipole forces).
Dipole-dipole interaction is attractive force which occurs between the positive end of one polar molecule and the negative end of another polar molecule.
London force is temporary force and it is the weakest intermolecular force. It is an attractive force that occurs when the electrons (e-) in two adjacent molecules occupy positions that make the atoms form temporary dipoles.
London forces the ion-ion interactions and dipole interactions and hydrogen bonding are all the intermolecular interactions that could occur in a container of only methyl benzoate. These are all the forces which are between the molecules. It may be attractive or repulsive forces between molecules or neighboring particles.
PLEASE ANSWER DUE TONIGHT: What happens if an enzyme is not functioning in a chemical reaction in a living organism that needs it?
The reaction stops.
The reaction proceeds, but much more slowly.
The reaction proceeds faster without the interference.
There is no change in the reaction rate.
If an enzyme is not functioning, the reaction it catalyzes proceeds much more slowly, as enzymes are crucial for reducing activation energy and allowing biochemical reactions to occur quickly enough to sustain life.
Explanation:If an enzyme is not functioning in a chemical reaction in a living organism that needs it, the reaction proceeds, but much more slowly. Enzymes are critical biological catalysts that greatly accelerate the rate at which chemical reactions occur within living organisms. Without the presence of enzymes to reduce the activation energy for reactions, biochemical processes could take substantially longer—ranging from hours to days—instead of occurring in less than a second as they typically do with functional enzymes.
An enzyme's ability to catalyze a reaction is due to its specificity for its substrate, which has a unique shape and electrical charge that matches the enzyme's active site. In addition, an enzyme operates most effectively under certain conditions, like optimal temperature and pH, further emphasizing its role in ensuring efficient biochemical reactions. In sum, if enzymes were not functioning, it would severely compromise the efficiency and viability of biological processes necessary for life.

A person has always enjoyed eating tuna fish. Unfortunately, a recent study of the mercury content of canned tuna found that chunk white tuna contains 0.67 ppm hg. The u.S. Environmental protection agency recommends no more than 0.1 μg hg/kg body weight per day. If the person weighs 72 kg, how often may he/she eat a can containing 6 ounces (1 lb = 16 oz) of chunk white tuna so that he/she does not average more than 0.1 μg hg/kg body weight per day?
According to the Food and Drug Administration, five of the most generally consumed fish, which are low in mercury content are canned light tuna, shrimp, catfish, pollock, and salmon. However, another commonly consumed fish, that is, white tuna or albacore exhibits more mercury in comparison to the light canned tuna.
In the given case, mass of tuna is 6 oz = 6 × 28.3495 = 170.097 grams
Maximum mass of Hg permitted for 72 Kg body weight per day will be,
= 72 × 0.1 = 7.2 micrograms in a day
The concentration of white tuna in Hg = 0.67 ppm = 0.67 × 10^ (-6)
Mass of Hg = concentration × mass
= 0.67 × 10 ^ (-6) × 170.97
= 113.96 micrograms
Time between the consumption = 113.96 ÷ 7.2
= 16 days, that is, once in every 16 days.
Answer:
The answer is in 16 days.

*A pseudoscorpion, a type of arthropod, hides under a beetle's wings
for protection and transportation, but does not affect the beetle.
*Rickettsia bacteria can only survive in eukaryotic cells,
which are destroyed when the bacteria replicates
A facultative parasite refers to a species, which may resort to parasitic activity, but is not completely dependent on any host for finishing its life cycle. Therefore, the growth of Armillaria fungi inside a tree's roots, making the tree to rot, but will survive even if the tree dies, is an example of facultative parasitism.
An obligate parasite refers to a parasitic species, which cannot finish its life-cycle in the absence of a suitable host. Therefore, rickettsia bacteria's tendency to surviving only in a eukaryotic cell is an example of obligate parasitism.
A long-term symbiosis or biological association in which members of one species attain benefits while those of the other species is neither harmed nor are benefited is known as commensalism. Hence, a pseudoscorpion, a kind of arthropod hiding under the wings of beetle for protection and transportation, however, it does not affect the beetle is an example of commensalism.
Predation refers to a biological association, where one species, the predator, kills and consumes another species, known as prey. A freshwater amoeba feeds on bacteria in the water is an example of predator and prey.
Facultative parasitism, Armillaria fungi grow within a tree's roots, causing the tree to rot, but will survive if the tree dies.
Explanation:The above given fungi is an example of facultative parasitism because in facultative parasitism the organism lives in host and provide harm to it but it is not totally dependent on host. It can survive after the death of host.
Part 2.Obligate parasitism, Rickettsia bacteria can only survive in eukaryotic cells,
which are destroyed when the bacteria replicates .
Explanation:The rickettsia bacteria is best example of obligate parasitism because in this type of parasitism, an host is obligatory for the survival and reproduction of organism. They need the host and host cell for the completion of their life cycle.
Part 3.Commensalism, a pseudoscorpion, a type of arthropod, hides under a beetle's wings for protection and transportation, but does not affect the beetle.
Explanation:The commensalism is a type of symbiotic interaction between two organisms, in which one get benefited while other neither get benefit nor harm.
Hence in this example of pseudoscorpion, one organism a pseudoscorpion is getting protection from beetle while beetle is unaffected.
Part 4.Predator and prey, A freshwater amoeba feeds on bacteria in the water.
Explanation:Predator pray relationship between two organism, one is benefited while other get harm.
In above example, amoeba uses water bacteria for their food while these bacteria die due to amoeba. So this is obvious predator pray relation.
