If the amino acids glycine, alanine and valine were combined in one molecule, what would the molecule be called?
Answer:
A tripeptide
Explanation:
Alanine (Ala), Glycine (Gly) and Valine (Val) are amino acids, i.e., organic molecules that contain at least an amino (–NH2) and one carboxyl (–COOH) functional group. The amino acids held together by peptide bonds, which are formed by a carboxyl group of one amino acid and an amino group of another one, in order to form a peptide. Thus, a tripeptide is a peptide composed of three amino acids joined by two internal (and sometimes three) peptide bonds. In the case above described, the tripeptide formed by the binding of Glycine, Alanine, and Valine can be abbreviated as Gly-Ala-Val (i.e., in this order).

plz can i get brainliest:)
Alkali substances has a pH greater than 7 hence it follows that the lye in soap has a pH over 7.
What is corrosion?
The term corrosion has to do with the waering away of a metal surface due to the action of oxidation. Hence the term applicable is corrosion.
The bases are know to be have a bitter taste and are slippery to touch hence the correct response is bases.
Water is a neutral substance, in the pH scale, a neutral substance has a pH of 7 hence the pH of water is 7.
Sulfuric acid is an acid and acids have a pH that is below 7 hence the pH of sulfuric acid is under 7.
Given the fact that alkali substances has a pH greater than 7, it follows that the lye in soap has a pH over 7.

what happens to a animal cell placed in a hypotonic solution
Answer:
If you place an animal or a plant cell in a hypertonic solution, the cell shrinks, because it loses water ( water moves from a higher concentration inside the cell to a lower concentration outside ). ... A single animal cell ( like a red blood cell) placed in a hypotonic solution will fill up with water and then burst.
Explanation:
Hypotonic solution is a solution which, contains lesser solute concentration. If animal and plant cells are kept in a hypotonic solution then endosmosis will occur. Endosmosis is a process in which the water molecules move from outside of the cell of lower solute concentration to the inside of the cell of higher solute concentration through the cell membrane or cell wall. Due to endosmosis, both animal and plant cells will swell.

What enzyme deficiency in RBC leads to hemolytic anemia due to oxidative stress?
In some cases, massive destruction of red blood cells caused death. This drug-induced hemolytic anemia was shown 30 years later to be caused by a deficiency of glucose 6-phosphate dehydrogenase, the enzyme catalyzing the first step in the oxidative branch of the pentose phosphate pathway.
in short terms, glucose 6-phosphate dehydrogenase
14. Kidneys are filters. As blood passes through the kidney, waste in the form of urine is
left behind. Tubes take the urine from the kidney to a storage bag called the bladder.
What can you conclude about blood leaving the kidney?
A. It moves to the bladder.
B. It has no water left in it.
C. It is ready to be used by the body.
D. It needs to have urine added to it
Answer:
D. It needs to have urine in it
Explanation:
They are located just below the rib cage, one on each side of your spine. Healthy kidneys filter about a half cup of blood every minute, removing wastes and extra water to make urine. The urine flows from the kidneys to the bladder through two thin tubes of muscle called ureters, one on each side of your bladder. The fluid that is filtered out from the blood then travels down a tiny tube-like structure called a tubule. The tubule adjusts the level of salts, water, and wastes that will leave the body in the urine. Filtered blood leaves the kidney through the renal vein and flows back to the heart.

6. Does the insect have a small body with large fan –shaped wings?
a. Yes…………………………………………………………………………… Order Lepidoptera
b. No………………………………………………………………………………Order Hymenoptera
Answer:
ORDER ODONATA
Explanation:
It is simple to read a dichotomous key. You only need to understand the technical terminology and to detailed observe your specimen. The key will lead you to the answer.
1. Does the insect have wings?
a. Yes………………………………………………………………………… go to step 2
b. No…………………………………………………………………………. Order Hemiptera
We only need to answer this question by looking at the image. In our example, yes, the insect has wings. So we need to go to question number two. Note: In the hypothetical case that the insect would not have wings, it would belong to the Hemiptera order.
2. Does the insect have parallel wings? (hint: Parallel wings don’t stick out to the side)
a. Yes……………………………………………………………………………… go to step 3
b. No………………………………………………………………………………. go to step 4
Ok, here it tells you that parallel wings do not stick out to the side. But in our example, wings do stick out, so the answer should be NO. This species does not have parallel wings. As it is a NO, we go to question number 4.
Note: In the hypothetical case that the insect would have parallel wings, we should read number 3.
4. Does the insect have 4 total wings?
a. Yes………………………………………………………………………………… go to step 5
b. No………………………………………………………………………………… Order Diptera
This one is easy. How many wings our specimen has? Four. Then it is a YES, and we go to question number 5. Note: In the hypothetical case that the insect would not have 4 wings, it would belong to the Diptera group.
5. Does the insect have long antennae?
a. Yes………………………………………………………………………………go to step 6
b. No……………………………………………………………………………… Order Odonata
Our insect has very short antennae. They are not long at all. So, the answer is NO, the insect does not have long antennae. This answer leads us directly to the order of our individual. ORDER ODONATA. Note: In the hypothetical case that the insect would have long antennae, we should read question number 6. And so on until we would reach the order.
ORDER ODONATA:
Dragonflies belong to this group. These insects characterize as having big eyes, and the separation between them depends on the species. They have an elongated abdomen, sometimes even longer than the wings. Their bodies must be robust to support the massive musculature that propels the wings during flight. The wings are long, big, and wide.
Usually, the males are much more colored than the females are.

What process is occurring in this picture at B?
Answer:
Translation
Explanation:
Translation is the second process that occurs in protein synthesis. It is the process whereby mRNA template is used to synthesize an amino acid sequence, which eventually becomes a protein.
The process of translation occurs in the cytoplasm (specifically in the ribosome). As depicted in this image, the mRNA produced during transcription is transported out of the nucleus into the cytoplasm. A RNA molecule called tRNA reads the mRNA sequence (codon by codon) and carries corresponding amino acid into the growing amino acid sequence.
Hence, according to this question, the process occuring at B according to this image is TRANSLATION.

Select one:
eaten by parasites
used by producers
invaded by viruses
consumed by decomposers
After a carnivore feeds on an organism, the rest of the dead body is: D. consumed by decomposers.
What is a carnivore?A carnivore is also referred to as a carnivorous animal and it can be defined as a type of animal whose food and energy requirements are primarily derived from animal products, especially by hunting and scavenging.
This ultimately implies that, a carnivore is an animal that only feeds on other animals such as deers, cows, zebras, rather than grasses or plants.
In conclusion, decomposers are a group of microorganism such as fungi and bacteria, that consumes the rest of the body of a dead or decaying organism after a carnivore has fed on it.
