Answer:
metabolism refers to all chemical reactions that allow to the cells carry out their functions
Explanation:
In a wide sense, the term metabolism refers to the chemical reactions that occur in the cells of a particular organism in order to sustain life. In a cell, the term metabolism can be delimited as all the chemical reactions inside the cell in order to carry out all cellular functions (e.g., growth, development, reproduction). Metabolic reactions can be divided into 1-catabolic reactions, which typically release energy and involve the breakdown of larger molecules into simpler ones, and 2-anabolic reactions, which typically require an input of energy stored in the chemical bonds of complex molecules.
Which of the following processes includes all of the others?
Select one:
a. Passive transport
b. Osmosis
c. Facilitated diffusion
d. Diffusion
Diffusion is described as the flow of individual molecules through a semipermeable barrier from a region of higher concentration to a region of lower concentration. Therefore (D) is the correct option.
Diffusion is the flow of molecules down the concentration gradient. Various types of diffusions are :
The DNA sequence TTT codes for the amino acid lysine. The DNA sequence TTC
also codes for lysine. What can you conclude from this information?
Answer:
The genetic code is degenerate and therefore mutations may go unnoticed.
Explanation:
Each triplet of nucleotide bases, which is known as a codon, encodes for a specific amino acid during translation. However, a single amino acid may be coded by different codons. It is for that reason that the genetic code is considered to be degenerate. In this case, Lysine amino acid can be encoded by both TTT (UUU in the mRNA) and TTC (UUC) codons, thereby a mutation T>C at the third nucleotide codon position does not affect the resulting protein (i.e., it is a silent mutation).
The two sounds heard through the stethoscope during a heartbeat are known as lub and dub. If the doctor detects an unusual lub
sound, evaluate which description could explain the atypical sound.
Answer: the description that could explain the atypical sound is known as HEART MURMURS.
Explanation:
The doctor makes use of instruments like the stethoscope to listen to the sounds of the heart while examining a patient. The sound heard in a normal heart beat is described as a "lub" and a "dub" sound.
The "lub" sound, which is called the first heart sound, is associated with closure of the atrioventricular valves at the beginning of a systole and the "dub" sound,which is called the second heart sound, is associated with the closure of the semilunar ( aortic and pulmonary) valves at the end of systole.
HEART MURMURS usually occurs when there are abnormalities of the valves which may occur due to congenital heart defects. It is classified according to when it occurs and these includes:
--> systole murmurs: these occurs during the first heart sound and,
--> Diastole murmurs: these occurs during the second heart sound.
Therefore the description that could explain the atypical sound is known as HEART MURMURS
Answer:
b.) the mitral valve does not close after the systolic phase.
A: None of the potential offspring would be male, because the potentially male zygote would have two X chromosomes, and the Y chromosome would be ignored.
B: The male offspring would all be red-green color-blind, because of interference from alleles on the Y chromosome.
C: The male offspring would have full-color vision, because of the presence of the extra X chromosome
D: There would be no change to the phenotypes of the possible offspring, because the extra X chromosome would not be active.
Answer: C the male offspring would all be red-green color-blind, because of interference from alleles on the Y chromosomes
Explanation: College board got it correct
The male offspring would all be red-green colour-blind, because of interference from alleles on the Y chromosome. Hence, option B is correct.
What is colour blindness?a diminished capacity to tell some colors apart. Frequently, the condition is hereditary. Medications and specific eye conditions are additional factors. Men are affected more than women.
Inherited color blindness is not treatable. Treating the underlying issue may be helpful if another condition is the cause of color blindness.
The X chromosome is where the genes that might cause red-green color blindness is handed down. Men are more likely than women to have red-green color blindness since it is X-chromosome-inherited. This is due to the fact that males inherit just one X chromosome from their mothers. Hence, option B is correct.

pls help me. with the help of diagram describe the structure of stomach
Answer:
The stomach is a muscular organ located on the left side of the upper abdomen. The stomach receives food from the esophagus. As food reaches the end of the esophagus, it enters the stomach through a muscular valve called the lower esophageal sphincter. The stomach secretes acid and enzymes that digest food.

During which of the following processes would carbon most likely be required?
A. Breaking of rocks
B. Generation of electricity
C. Making of glucose
D. Running of cars
I think its C but when I looked the question up to check my answer, someone said they put C and got it wrong. I know we take fossil fuels out of the ground and burn them to create electricity or to make our cars run. and that burning fossil fuels releases carbon dioxide back into the air. And I know that carbon dioxide, water, and light make glucose.
Answer:
D
Explanation:
Answers D
Answer:
Glucose
Explanation:
During photosynthesis, plants take in carbon from the atmosphere so that they can create glucose. During cellular respiration, living things give off carbon as a waste product. This gives the carbon back into the air.

You were with your younger cousin playing at the park and he has mixed up his legos in the sand.
Explain how you could separate this mixture.
Answer:
You can use a tea net to separate the Legos and the sand. When you scoop up the sand into the net, the sand will be sifted away because it is smaller than the holes in the tea net. But, the LEGOs are much bigger, so they will remain inside the net.

5 The theory of plate tectonics was, at first, rejected by most scientists. Now most geologists accept that tectonic plates exist and that these tectonic plates can and do move. What is responsible for the change in how scientists think about plate tectonics? A New evidence was discovered that made scientists revise their ideas. B. Tectonic plates have begun to move faster and faster over time. C There are more people studying science now than in the past. D Scientists can now travel underneath the plates and observe their motion.
Tectonic plates have begun to move faster and faster, leading to a change in scientists' thinking about plate tectonics. Hence the correct option is (B).
What is Tectonic Plates?
Tectonic plates are also known as lithospheric plates. It is a massive, irregularly shaped slab of solid rock that is composed of both continental and oceanic lithosphere. The size of the plates varies greatly from a few hundred to thousands of kilometres.
The plates are the largest in the Pacific and Antarctic Oceans. Its thickness also varies greatly, ranging from less than 15 km for young oceanic lithosphere to about 200 km or more for ancient continental lithosphere.
Earth's rigid surface known as the lithosphere acts as a skin that rests and slides over a semi-molten layer of rock called the asthenosphere. It can break into many different plates because of differences in the density of rock and differences in subsurface heating between one region and the next.
Thus, Tectonic plates have begun to move faster and faster, leading to a change in scientists' thinking about plate tectonics. Hence the correct option is (B).
