The removal of the nitrogen-containing part of an amino acid leaves behind its carbon skeleton. This includes the central ">-carbon attached to a carboxyl group, an amino group, and a variable side chain.
When the nitrogen-containing portion of an amino acid is removed, what remains is the carbon skeleton. The ">-carbon is central to the structure of an amino acid and is attached to a carboxyl group (C=O), the amino group (N-H), and a variable side chain, or R group, which distinguishes one amino acid from another. In a protein, the amino acids are linked by peptide bonds to form chains, where individual amino acids are referred to as residues.

Plant A and Plant B are heterozygous for a gene that expresses their tall trait (Tt). Upon crossing, what is expected in the offspring, assuming random chromosome segregation?
Answer:
The Plant A is heterozygous for the gene expressed their tall trait (Tt) and Plant B is also heterozygous for the same trait.
( Plant A ) Tt X Tt ( Plant B) = TT Tt Tt tt
The products are 75 per cent tall by phenotype and 25 per cent dwarf by phenotype.
If the cross between the two heterozygous gene is done which shows the trait as tall, and then the offspring will have 75% as tall plant and 25 % as dwarf plant.

Skulls can reveal many things about our hominid ancestors. What aspect of hominids is not related to skull anatomy?
A. What they ate.
B. Their hair and skin color.
C. Whether they stood upright.
D. The shape and size of their brain.
The answer is B.
Choice A is wrong because what they ate is how the skull is shaped and how the skull uses itself to find and eat food.
Choice C is wrong because it went over that in the Gizmos activity
Choice D is wrong because their brain was in their skull to help shape how the skull looked like.
The correct answer is - B. Their hair and skin color.
The hair and skin color of the hominids is not related to the shape and size, or rather the anatomy of the skull. The development of hair and skin color is actually dependent on the surrounding environment, since it can be used for camouflage, for protection of cold, or protection of the sun, but it has nothing to do with the bone structure of the skull.
The anatomy of the skull is defined by the eating habits, the way of motion, the size and the shape of the brain.

A clerk can sort 375 sheets of per hour. If there are 225 sheets in an inch, how long will it take her to file 125 inches of loose leaf?
Answer: 75hours
Explanation:
If there are 225 sheets in one inch that means that in 125 there will be 28,125 sheets because you will have to multiply. And if you can sort 375 pero hour that will mean than in 75 hours you will sork all sheets because 28,125 divided by 375 sheets pero hour will give 75 hours.
125 inch * 225 sheet/ inch= 28,225 sheets
28,225 sheets divided by 375 sheets/hour=75 hours
It will take them 75 hours to file all the sheets in the bundle.
What is speed?
The rate of change of position of an object is called speed. Speed is a scalar quantity, which means the measurement of direction is not important in the case of speed.
That is why it is different from velocity which is a vector quantity. In velocity, the rate of change of motion is measured in a particular direction.
Because speed measures the rate of a change in motion, it is not useful to be used in this case.
In this case, the rate of filing is 375 sheets/hour.
There are 225 sheets in an inch and a total of 125 inches of sheets.
So the total number of sheets is equal to
225 × 125 = 28125 sheets.
Rate of filing = 375 sheets/hour
So, 28125/375 = 75.
Therefore the time required to file all of the sheets is equal to 75 hours.

Which of the following is not a piece of molecular evidence supporting the endosymbiotic theory?
The mitochondria and chloroplasts are much different in structure than bacteria. Hence the correct option is a.
One piece of molecular evidence supporting the endosymbiotic theory is the similarity between the DNA of mitochondria and chloroplasts and that of bacteria. This similarity suggests that mitochondria and chloroplasts may have originated from free-living bacteria that were engulfed by ancestral eukaryotic cells and formed a symbiotic relationship.
Additionally, the presence of ribosomes in mitochondria and chloroplasts that resemble those found in bacteria further supports this theory. Moreover, the mechanism of division by fission, which is similar to bacterial reproduction, observed in some organelles like mitochondria and chloroplasts provides further evidence for their bacterial origins.
However, the structural differences between mitochondria, chloroplasts, and bacteria do not directly support the endosymbiotic theory but rather suggest evolutionary adaptations that have occurred over time. Therefore, option A is not a piece of molecular evidence supporting the endosymbiotic theory. Hence the correct option is a.

during dna replication in a human cell, 6 billions bases must be paired properly. which characteristic of dna best allows for high level of accuracy during this process
Answer: The complementary base pairing helps in proper pairing of the bases.
Explanation:
The complementary of base pair shows that the adenine will only bind to the thymine and the guanine will only bind to the cytosine and with any other base pair.
So, the template no matter how long it is, the adenine in them will bind to the thymine and the cytosine will bind to the guanine.
The bonds in between are double hydrogen bond in case of adenine and thymine and triple hydrogen bond in case of guanine and cytosine.
This aids in pairing of 6 billion bases during the time of DNA replication in human beings.
Mice eat corn. Hawks eat mice. Which term describes the corn in this food chain?
a. secondary consumer
b. primary consumer
c. producer
d. decomposer
The correct answer is producer.
The term producer means the autotrophic plants that makes food for themselves. The primary consumer such as mice feeds on the producer (corn) for their energy requirement. Producers lie at the first level of the food chain. Producers are the blue-green plants that makes food by the process of photosynthesis by using sunlight.

In tunicates, the anus empties into the excurrent siphon. what is the advantage of this anatomical arrangement?
Final answer:
In tunicates, having the anus empty into the excurrent siphon expels waste away from the organism, preventing contamination of their feeding system and maintaining a clean environment.
Explanation:
The anatomical arrangement of the anus emptying into the excurrent siphon in tunicates provides notable advantages. Most tunicates are stationary, which means they rely on water movement around them for essential processes like feeding and excretion. The incurrent siphon brings in water that contains food particles and plankton, which are then filtered by the pharyngeal slits and trapped in a mucus net. This filtered material is then ingested and processed by the digestive system. The presence of the anus in the excurrent siphon is beneficial as it ensures that waste is expelled in a directed manner, away from the animal, through the excurrent siphon. This efficient waste elimination helps to prevent contamination of the suspension feeding system and maintains the organism's living environment clean from their own excreted waste, which is crucial for an organism living in a fixed location.

What name is given to organisms that convert the carbon in organic compounds into carbon in carbon dioxide?
Non-photosynthetic organisms convert the carbon in organic compounds into carbon in carbon dioxide.
What are organic compounds?The process by which organisms that engage in photosynthetic growth, like plants and algae, convert inorganic carbon compounds (typically carbon dioxide) into organic carbon compounds examples of processes that cause carbon to transfer from one reservoir to another include photosynthesis, respiration, and combustion.
The process of cellular respiration involves the oxidation of biological fuels in the presence of an inorganic electron acceptor, such as oxygen, to generate significant amounts of energy that are used to power the major production of ATP.
Therefore, cellular respiration is a series of metabolic processes that take place inside of cells to transform biochemical energy from food into a substance known as adenosine triphosphate.
