This sequence best represents
A) an arid region that experienced mostly uplifting forces
B) an arid region that experienced mostly erosional forces
C) a humid region that experienced mostly uplifting forces
D) a humid region that experienced mostly erosional forces
The correct answer is B. An arid region that experienced mostly uplifting forces.
Explanation
According to the graph, it can be seen that 25 million years ago the illustrated area was arid and the earth's crust had a fracture that eroded to form a table 15 million years ago as shown in the second illustration. Later, it is shown how the erosion continued to act on this area until creating different plateaus and a plain in the present time. The key to understanding these illustrations are the layers of the earth's crust that are shown because it shows how some layers are disappearing or reducing their area while the lower layers are being exposed. Therefore, the correct answer is B. An arid region that experienced mostly uplifting forces.
Lactose when digested, it is hydrolyzed by lactase into its monomers, which are then absorbed by blood. Following are test results from a person done after 2 hours of drinking a lactose rich solution. The blood glucose levels were 80, 110, 140 and 160 mg / dL tested for every 30 minutes. Based on this information does this person have lactose intolerance?
Answer: Based on the information, the person DOES NOT have lactose intolerance because glucose levels significantly increases in normal individuals after a lactose rich meal.
Explanation:
Lactose is a disaccharide carbohydrate which when taken (found mostly in diary products) is hydrolyzed by lactase into its monomers, which are then absorbed into the blood. The hydrolysis of lactose gives glucose and galactose which is carried out by the digestive enzyme lactase. Deficiency of the lactase enzyme gives rise to a disorder known as LACTOSE INTOLERANCE.
The diagnosis of lactose intolerance or lactase deficiency can be confirmed by measuring the plasma glucose concentrations, as in glucose tolerance test, after giving an oral load of lactose rich solution. If the disaccharide (lactose) cannot be hydrolysed, the constituent monosaccharides cannot be absorbed and the concentrations of plasma glucose rise VERY little.
But the fasting blood glucose done after 2 hours of drinking a lactose rich solution showed a typical rise in blood glucose levels which were 80, 90, 100, 110 and 120 mg/ dL tested for every 30 minutes. This indicates that the individual does not have lactose intolerance because the glucose gotten from hydrolysed lactose was absorbed and cause a significant rise in blood levels.

Answer:
c
Explanation:
the question is asking about the energies. when the two cars are moving towards each other they are accelerating meaning they have kinetic energy. when they collide; on rebounding, the car regains a smaller amount of kinetic energy – this time travelling backwards. So the overall process is that kinetic energy becomes heat and spring potential energy, which results in heat, smaller kinetic energy and, hopefully, surviving occupants. so the speed of the car before and after will show the energy change
4. Examine the codon chart and list all of the codons that code for the amino acid leucine. List them: Second Bar U code ; amino acid cade amung aca" code arning old code, amino acid LOU UCA FORCE STICI DCA UGG Glou. CGC gla Firal Base Third Base as AUC mrt WENT GOO VA
Answer:
The codons that code for LEUCINE amino acid are:
1. UUA
2. UUG
3. CUU
4. CUC
5. CUA
6. CUG
Explanation:
A CODON is a group of three nucleotides in the mRNA molecule that specifies a particular amino acid. It represents a trio combination of nucleotides (A, G, C, U). There are about 64 possible codons formed from four nucleotides used in a combination of three's i.e 4³ = 64. All the codons collectively form the GENETIC CODE, which is used by all known living organisms.
However, since there are only 20 amino acids in nature and 64 possible codons, more than one codon encodes an amino acid. This means that the genetic code is DEGENERATE or REDUNDANT. Hence, in this case involving the amino acid: LEUCINE, the six (6) codons that specify it (depicted in the attached genetic code) are as follows:
- UUA
- UUG
- CUU
- CUC
- CUA
- CUG
A codon is a three nucleotidic sequence that carries genetic information to assembly an amino acid to the growing protein. The six codons that code for leucine are UUA, UUG, CUU, CUC, CUA, and CUG.
----------------------------------------
During translation, the ribosome reads mRNA in 5' to 3' direction. While doing so, tRNA recognizes the codons and adds the correct amino acid to the growing peptidic chain.
A codon is a three nucleotidic sequence that carries genetic information to assembly an amino acid. One codon determines which amino acid is going to be addede to the protein.
In nature, thete are 20 amino acids that compose the proteins, and more than 20 possible codons combinations. So one amino acid is coded by more than one codon.
The amino acid LEUCINE is coded by six codons. They are,

The ability to taste the chemical PTC is determined by a single gene in humans with the ability to taste given by the dominant allele T and the inability to taste by the recessive allele t. Suppose two heterozygous tasters (Tt) have a large family. What is the likelihood that their first child will be a taster
Answer:
75%
Explanation:
This question involves a single gene coding for the ability to taste the chemical PTC. The allele coding for the ability to taste (T) is dominant over the allele coding for the inability to taste (t). This means that an heterozygous individual will have the ability to taste PTC.
According to this question, if two heterozygous tasters (Tt) cross to have a large family i.e. Tt × Tt, the following gametes will be produced by each parent;
Tt = T and t
Using these gametes in a punnet square (see attached image), the following proportion of offsprings will be produced:
TT, Tt, Tt - Tasters (3/4 or 75%)
tt - Non-taster (1/4 or 25%)
Note that based on the question asked, there is a 75% probability that their first child will be a taster because there is equal segregation of alleles into gametes.

3)blood flows simultaneously into the atria.
4)the right side of the heart receives

Answer and I will give you brainiliest
sorry im not sure this is correct but i think the one that is incorrect is
4) the right side of the heart receivesblood and the left side pumps blood.i will put the explanation just incase you want to choose the answer by yourself after knowing it. I hope you read this too..
Explanation1)Blood flows in two loops
This one is already correct if it happens in human heart circulatory system. Human's heart beat in two loops and this is really useful because of enough pressure to pump blood to the body. This two loops name is double circulatory system.However fish has single circulatory system where they only pump blood once. So this one also can be wrong but if the answer only one, this one can pass.2)the ventricles contract simultaneously to pump blood outside the heart.[✓]
This one already correct, the heart pump blood to the body through aorta and to the lungs through pulmonary artery.3)blood flows simultaneously into the atria.
This one also correct, because the blood come to the atria first to go to the left ventricle. Both of left and right ventricles are working simultaneously.4)the right side of the heart receives
blood and the left side pumps blood.
This one can be correct but also wrong. I choose this one wrong because there's no more explanation in this statement. The right side of heart can also pumps blood and left side of heart also can receives blood.The right side of your heart receives oxygen-poor blood from your veins and pumps it to your lungs and also The left side of your heart receives oxygen-rich blood from your lungs and pumps it through your arteries to the rest of your body.Note for moderators that read this#Moderators please don't be mean, dont delete my answers just for approval from your senior or just to get the biggest moderation daily rank.
