If I were a marine biologist who wanted to study organisms that are capable of chemosynthesis, I would collect organisms for my research from a variety of deep ocean environments. These environments include hydrothermal vents, methane seeps, cold seeps, and whale falls.
Hydrothermal vents are located near tectonic boundaries in the deep ocean, and are characterized by high concentrations of hydrogen sulfide, a compound that serves as a source of energy for many organisms. These vents are home to a variety of chemosynthetic bacteria, including species of bacteria that can directly use hydrogen sulfide for chemosynthesis. I would collect organisms from hydrothermal vents by using submersible vehicles that can reach the depths at which these vents are found.
Methane seeps are another environment where chemosynthetic organisms are found. Methane is released from seeps, and this methane serves as a source of energy for chemosynthetic bacteria. I would collect organisms from methane seeps using submersible vehicles equipped with sampling devices, such as coring devices or sediment traps.
Cold seeps are another environment where chemosynthetic organisms are found. These seeps are characterized by the presence of methane, which is produced by bacteria. I would collect organisms from cold seeps using submersible vehicles equipped with sampling devices, such as coring devices or sediment traps.

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.
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.
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.
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.

Answer:
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
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).

Which term describes resistance to change in motion?
A. acceleration
B. inertia
C. net force
D. velocity
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

Think about a model that you can construct that could be used to show the difference in prokaryotic and eukaryotic cells. In 6 complete sentences(3 for each type of cell), explain the process you would use to construct the model and how you would use the model to explain the differences between prokaryotic and eukaryotic cells to your classmates.
Answer:
Prokaryotic cell-- no organelles, no membrane.
Eukaryotic cell -- Have organelles and membrane.
Explanation:
For the model of prokaryotic cell, we construct the model by removing organelles from the cell whereas in the eukaryotic cell, we add the organelles because in eukaryotic organisms, organelles are present in the cell that performs specific function. In the model of prokaryotic cell, we have to remove membrane around the nucleus whereas membrane president around the nucleus. In the prokaryotic cell, nucleus is not visible while on the other hand, in eukaryotic cell, the nucleus is visible and can be differentiate from other organelles.

A. Write two sentences explaining how carbon returns from the air to the ground.
Answer:
In the atmosphere, carbon is attached to oxygen in a gas which is called carbon dioxide and through the the process of photosynthesis, it is pulled from the air to produce food made from carbon for plant growth. And through food chains, the animals that eat plants get that carbon and so do the animals that eat those animals.
When an animal dies, their bodies as well as wood and leaves decaying brings the carbon into the ground.

only one of the other DNA bases. Using the base-
pairing rules, which of the following is the correct
order of bases that would pair with the following
string of bases on a DNA molecule:
Adenine, guanine, guanine, cytosine, thymine,
adenine
O A. Cytosine, thymine, thymine, adenine,
guanine, cytosine
O B. Thymine, cytosine, cytosine, guanine,
adenine, thymine
O C. Thymine, adenine, adenine, guanine,
cytosine, thymine
O D. Guanine, adenine, adenine, thymine,
cytosine, guanine
Answer:
The correct answer is - B. Thymine, cytosine, cytosine, guanine, adenine, thymine.
Explanation:
According to the base-pairing rule, the one purine binds with a specific pyrimidine always, the purine adenine (A) only pairs with the pyrimidine thymine (T) and similarly, the purine guanine (G) only pairs with the pyrimidine cytosine (C) in DNA, and in RNA the purine adenine (A) binds with the only uracil.
Here, the bases are -
Adenine, guanine, guanine, cytosine, thymine, adenine
the string of their base pair would be:
Thymine, cytosine, cytosine, guanine, adenine, thymine.
