Among all the statements that are given in the question are true except the statement that the DNA lagging strand moves away from the helicase. The correct answer is statement number 5.
What are helicases ?These are the enzymes that bind and remodel nucleic acid and nucleic acid protein complexes.
DNA helicases are the enzymes that are playing a role in the separation of two strands and when the two strands are separated in that case the two strands are basically separating or disrupting the structure of the DNA helix.
To unwind duplex of DNA, DnaB helicase has a requirement a 5'-overhanging single strand of DNA where helicase is 5' to 3' in the helicase that is travelling along the lagging strand as it is unwinding duplex of DNA. Various helicase, which are said to be dimeric where it travels from 3' to 5' direction along the leading single strand.

A group of students were interested in showing photosynthesis occurring visually. They decided to use bromothymol blue which is an indicator that turns green when there is a high concentration of carbon dioxide and blue when there is a low concentration of carbon dioxide in water. All the tubes started out blue, but students blew carbon dioxide into two of the test tubes turning them green. They left one test tube of each color as their control and put a piece of aquatic plant in the other two tubes. Then, they put all four of these tubes outside (Monday 7 am). When the students checked their tubes in the afternoon (Monday 1 pm), they were so excited to see that tube D had turned blue! Carbon dioxide was going away and being replaced with oxygen. When the students checked their experiment early the next morning, tube B and D had both turned green! Did photosynthesis occur during the experiment? Support your claim with evidence explain your reasoning.
Answers
Answer:
photosynthesis did not occur.. because if photosynthesis had occured oxygen would be produced..but the tubes turned green proving there was more carbondioxide than oxygen Which proves photosynthesis didn't take place.

As the test tube turned green, it means that photosynthesis did not occur in the test tubes.
What is bromothymol blue?Bromothymol blue (BMB) is a dye that turns yellow when exposed to acid. When carbon dioxide is added to a solution, it produces carbonic acid, which lowers the pH.
When the pH is greater than 7.6, BMB is blue, green when the pH is between 6-7.6, and yellow when the pH is less than 6.
Carbon dioxide dissipates in water to produce a weak acid. As a result, an acid-base indicator like bromothymol blue (BTB) can be used to detect the presence of CO2.
The person basically use bromothymol blue as an indicator to determine how much CO2 remains in test tubes containing light-exposed plants.
Thus, as there were some drawbacks in the experiment, the test tube B and D got green color, which means the level of carbon dioxide were more. This implies, photosynthesis did not occur.

In many tropical rainforests, people clear land by cutting down trees and burning them. After a few years, the soil runs out of nutrients and cannot be farmed any longer. How does this affect Earth's atmosphere?
Answers
Answer:
Land will convert into desert eventually
Explanation:
When the soil gets devoid of nutrient, it will be unable to support trees, plants or vegetation of any type. Trees and plants are responsible for holding the soil tightly and prevent it from eroding.
Once there will be no nutrient in soil, there will be no trees, plants or vegetation and hence there will be no mechanism to prevent soil erosion. Thus, the soil will erode due to deforestation and the land will convert into desert eventually

Question options:
competition
predation

Answers
Male kangaroos that kick one another and bighorn rams will gather and crash their heads into each other prior to mating season are examples of competition.
What is competition?Competition is a type of ecological relationship in which two organisms contend for the same resource (e.g., food).
Competition can be divided into intraspecific competition and interspecific competition.In general, intraspecific competition makes reference to competence for reproduction.In conclusion, male kangaroos that kick one another and bighorn rams will gather and crash their heads into each other prior to mating season are examples of competition.

Which term describes resistance to change in motion?
A. acceleration
B. inertia
C. net force
D. velocity
Answers
Answer:
Newton's second law of motion states that the accelaration of an object is directly proprotional to the force acting upon it. In symbols, we can write this as
[tex]F= ma[/tex]
Wher F is the force acting upon the object, m is the object's mass, and a is the object's acceleration. We can multiply both sides of this equation by 1/m to get the equivalent equation
[tex]\frac{1}{m} F= a[/tex]
What happens when we make m higher and higher? Well, that fraction 1/m gets closer and closer to zero. The same force accelarates the object less and less as that object becomes more massive. This consequence of Newton's second law, the resistance of massive objects to changes in acceleration, is called inertia, and it's one of the main expressions of mass in classical mechanics.
Answer:
acceleration

In the early 1900s, three species of goatsbeard wildflowers, T. dubius, T pratensis, and T. porrifolius, were introduced to the United States. Each of the species had a chromosome number of 2N. In the 1930’s, a few populations of offspring from the original wildflowers were identified as having a chromosome number 4N. What does this data suggest about speciation.
A. Speciation has occurred because the original species of wildflowers produced populations of viable offspring.
B. Speciation has occurred because breeding between the offspring and original populations would not be possible.
C. Speciation has not occurred because the offspring of the original wildflowers were not introduced into a new area.
D. Speciation has not occurred because the offspring inherited identical genetic information to the original wildflowers.
Answers
Answer:
B. Speciation has occurred because breeding between the offspring and original populations would not be possible.
Explanation:
Speciation has occurred in the species due to no breeding between the offspring and original populations because the offspring and original species has different number of chromosomes in their DNA. Due to this difference in the chromosome number in the DNA, there is no chance of breeding between offspring and original species. Speciation is the evolutionary process by which populations of organism evolve with the passage of time and become different from the original species.

The correct answer is -
gly-met-arg-phe-val-pro
Explanation:
The production of the amino acid chain or sequence from the desired DNA sequence is called the protein synthesis or central dogma that involves two processes, transcription and translation. Transcription is the process of transcribing the information encoded in the DNA sequence into a complementary mRNA sequence. The translation is the second process that involves the translation from mRNA to a specific amino acid.
mRNA sequence is complementary to the DNA
so, DNA - CCC-TAC-CGC-AA-CG-CC
mRNA - GGG-AUG-CGC-UUU-GUC-GG
and amino acid from the chart : gly-met-arg-phe-val-pro

explain the effects of the production of large amounts of antidiuretic hormone in the human body
Answers
Answer:
Antiuretic hormone is a hormone that performs functions related to the reabsorption of water molecules through of the kidneys and with the decrease in the amount of urine accumulated in the body. An excess of antiuretic hormone conditions a retention of water and the elimination of sodium in the urine
Explanation:
Antidiuretic hormone (ADH) participates in regulating the water balance in the body, controlling the amount of water reabsorbed by the kidneys after they have filtered waste from the blood. Excess ADH leads to increased water reabsorption in the collecting duct, with increased urinary osmolarity. If there is too much ADH, water is retained, blood volume increases and affect can lead to nausea, headaches, disorientation, lethargy and hyponatraemia (decreased sodium concentration in the blood).
