C. Amino acids.
D. Monosaccharides
Please help!
Amino acid building blocks make up proteins. Thus, the right response to the question is (c).
How do proteins become made?A complex collection of molecules known as a ribosome is used by cells to assemble proteins. The ribosome puts amino acids in the correct order and connects them with peptide bonds. A polypeptide chain—a lengthy collection of amino acids—is produced by this procedure, known as translation.
Why do proteins matter in biology?Amino acids make up the chemical substances known as proteins. Up to four levels of structure can be found in proteins. Different proteins each have a complicated structure that gives them special characteristics. Proteins called enzymes speed up biological processes in cells. Proteins known as antibodies hunt down and kill infections.

Discuss three kinds of waste removal that humans must remove from their bodies, and explain why waste removal is important to living organisms.
The three types of waste removal are:
1. Urea
2. Metabolic gases
3. Non-digested food
Urea is the waste formed in our body as a result of protein break down which is excreted as a major component of urine
Metabolic wastes like CO2 are formed as a result of cell restoration that is released through the lung's expiration.
Non-digested food in the intestine is removed from the body as faeces
Answer:
Urine, sweat, and carbon dioxide
Explanation:
A type of waste is urine because uric acid is removed from the kidneys in the form of urine. Another waste product is when excess water is removed from the skin in the form of sweat. The 3rd waste that is removed is carbon dioxide which is removed from the lungs be exhaling. Waste removal is important to living things because it controls homeostasis and it removes toxic waste, and removes things that are no longer needed in the organism.
92ml 3.0 fl oz what is the ratio
The ratio between 92 mL and 3.0 fl oz is 46 : 44, or it can be further simplified to 23 : 22.
To find the ratio between 92 mL and 3.0 fl oz, we need to convert the units to a common measurement. Let's convert 3.0 fl oz to milliliters (mL).
1 fluid ounce (fl oz) is equal to approximately 29.5735 milliliters (mL).
Therefore, 3.0 fl oz is equal to 3.0 * 29.5735 = 88.72 mL (rounded to two decimal places).
Now we can express the ratio between 92 mL and 88.72 mL:
92 mL : 88.72 mL
Simplifying the ratio by dividing both sides by the greatest common divisor, we get:
46 : 44
So, the ratio between 92 mL and 3.0 fl oz is 46 : 44, or it can be further simplified to 23 : 22.

Meiosis and mitosis differences and similarities
Answer:
A. Similarities between mitosis and meiosis include:
both are processes of cell division or the creation of daughter cells from a parent cell
both go through the phases: prophase, metaphase, anaphase, and telophase and cytokinesis
both use most of the same machinery of cell division including centrosomes, spindle fibers, etc.
B. Differences between mitosis and meiosis include:
Meiosis is used in sexual reproduction to make four haploid (n) daughter cells from one parent cell.
Mitosis is used for growth, replacing old cells, and asexual reproduction. One parent cell makes more
Meiosis happens in two stages, or two rounds of division, known as meiosis I and meiosis II. Mitosis only involves one round of division, or division of the cytoplasm.
During meiosis, crossing over occurs, which increases the genetic variation of gametes. This does not happen in mitosis.

The pea aphid, a type of insect, contains light-capturing pigments in its exoskeleton. Scientists hypothesize the pea aphids gained the ability to synthesize these pigments from genes transferred from fungi during evolution. While pea phones do not have chloroplasts or fix carbon, researchers have found that pea aphids with more pigments have higher levels of ATP than those fewer pigments. Pea aphids also have been shown to increase production of ATP when exposed to sunlight.
Based on this information, is the pea aphid a true autotroph?
The pea aphid isn't a true autotroph because it is unable to use the energy from sunlight.
What is a true autotroph?A true autotroph is an organism that produces biomass by a chemical process called photosynthesis.
This type of autotroph generates biomass by means of photosynthetic cycles of production.
In conclusion, the pea aphid isn't a true autotroph because it is unable to use the energy from sunlight.

Temperature influences chemical reactions. Glow sticks use chemical reactions to produce light. One kind of glow stick produces light for about 4 hours on a summer night. What will happen to this kind of glow stick when one is used on a very cold winter night?
A. It will be dimmer and not last very long.
B. It will be dimmer and last longer.
Answer:
A. It will be dimmer and not last very long.
Explanation:
Hello.
In this case, since warmer temperatures favor the chemical reactions that produce lights, we can infer that lower temperatures such as those during very cold winter nights will not favor the reaction but disfavor them, causing them to undergo slower, less efficiently and lasting for less time, therefore, answer is A. It will be dimmer and not last very long.
This is supported by the theories explaining how fast chemical reactions undergo upon different temperatures conditions, which commonly, at higher temperatures, reaction rates are higher.

Astronomers have used several methods to derive estimates for the age of the universe. Identify the ways in which astronomers have done so from among those listed below. Astronomers determine estimates for the age of the universe from...
(1) Hubble expansion rate
(2) Uranium-238 abundance in old stars
(3) Radioactive dating of old Earth rocks
(4) Dark energy abundance
(5) Globular cluster ages
Choose all of the correct answers
The Astronomers determine estimates for the age of the universe from (1), (2), (3), and (5).
What is universe?The entirety of time, space, and everything in them, including all known types of matter and energy, make up the universe. Everything that exists is included in it, from the tiniest subatomic particles to the largest known formations, such galaxies and superclusters.
Astronomers have arrived at their estimates for the universe's age in the following ways:
(1) Hubble expansion rate: Using this technique, the redshifts of far-off galaxies are used to calculate the pace at which the universe is expanding. By projecting backwards from the universe's present expansion rate, the age of the universe can be determined.
(2) The amount of the radioactive element uranium-238 in old stars may be measured, and its decay rate can be used to determine the age of the stars and, by extension, the age of the universe.
(3) Radioactive dating of old Earth rocks: This technique entails figuring out the ages of the planet's oldest rocks using radioactive dating methods, which offers a more conservative estimate of the universe's age.
(5) The age of the oldest globular clusters in the Milky Way galaxy can be used to calculate the age of the universe using this approach, which is number five.
Thus, the appropriate choices are (1), (2), (3), and (5). Although it is employed in other cosmological investigations, the amount of dark energy is not used to directly calculate the age of the universe.

Case Study-Bob
Bob wakes up in the middle of the night with excruciating pain radiating from his left posterior flank that is radiating dow
blood in his urine, and finds it difficult to stand up straight or walk.
1. What is Bob's diagnosis?
Based on the symptoms described, Bob's diagnosis could be kidney stones or renal calculi.
Kidney stones are hard deposits that form in the kidneys and can cause severe pain when they move through the urinary tract. The excruciating pain originating from the left posterior flank and radiating downward is a characteristic symptom of kidney stones.
The presence of blood in the urine, a condition known as hematuria, is also common with kidney stones due to irritation and injury to the urinary tract.
Bob's difficulty in standing up straight or walking can be attributed to the intense pain caused by the movement of the kidney stone, which can make it challenging to find a comfortable position. The pain often comes in waves and can be described as one of the most severe pains experienced.
To confirm the diagnosis, Bob should seek medical attention for a thorough examination.
The doctor may perform imaging tests, such as a CT scan or an ultrasound, to visualize the kidney stone and determine its size and location.
Treatment options may include pain management, medication to facilitate the passage of the stone, or, in more severe cases, surgical intervention to remove the stone.
