Which nitrogenous base would pair with adenine during DNA replication?
A
O cytosine
<
B
O guanine
C
Othymine
D
ouracil

Answers

...........The answer is C


Replication relies on complementary base pairing, that is the principle explained by Chargaff's rules: adenine (A) always bonds with thymine (T) and cytosine (C) always bonds with guanine (G).

The nitrogenous base would pair with adenine during DNA replication is othymine. Thus, option C is correct.

What are nitrogenous base?

Replication relies on complementary base pairing, that is the principle explained by Chargaff's rules and adenine (A) always bonds with thymine (T) and cytosine (C) always bonds with guanine (G). 18% became cytosine pairs with G. A pairs with T. T and C are not complementary base pairs, but we know that if molecules consists of 32% T, it must have 32%.

The discovery of the structure of DNA was useful because it revealed how mRNA was used to make proteins. There are four nitrogen bases of DNA nucleotides are such as adinine, thymine, guanine and cytosine.

HDL stands for high-density lipoprotein or good cholesterol which absord cholesterol and send it to lever. The lever then flushes it from the body.  High-density lipoprotein can lower your risk for heart disease and stroke.

Therefore, The nitrogenous base would pair with adenine during DNA replication is othymine. Thus, option C is correct.

3. Give one reason why the reaction, ADP + P > ATP + H20, requires energy input.
(Hint: Notice the charges of the molecules in the top figure.)

Answers

Answer:

Both ATP and Phosphates have a negative charge. Energy is used so that the electrons do not repel each other.

Explanation:

Phosphates and ATP share the property of having a negative charge. In order to prevent the electrons from repelling one another, energy must be applied.

Why ATP formation need energy?

The hydrolysis of ATP to ADP is reversible, just like the vast majority of chemical processes. Through the process of the opposite reaction, ATP can be regenerated from ADP using Pi and ADP. Since the hydrolysis of ATP results in the release of energy, the synthesis of ATP must involve the addition of free energy.

Phosphates and ATP share the property of having a negative charge. In order to prevent the electrons from repelling one another, energy must be applied.

By rupturing and then reforming the bonds that hold its phosphate groups together, ATP is able to effortlessly release and store energy. Because of this property, ATP is an excellent candidate for the role of fundamental source of energy for each and every cell.

Genetic modification is a method farmers use so their crops are resistant to disease or cold temperatures. Which of these is a negative consequence of using genetically modified organisms?
Genetic modification increases the extinction rate of the modified organism.
Genetic modification decreases the population size of the modified organism.
Genetic modification increases the carrying capacity of the modified organism.
Genetic modification decreases the genetic variation of the modified organism.

Answers

Answer:

Genetic modification decreases the genetic variation of the modified organism.

Explanation:

Genetic modification is widely used in agriculture for increasing productivity and to make crops resistant to diseases but along with advantages there are some disadvantages of genetic modification that involve decreases the genetic variation of the modified organism.

This is so because the DNA or genetic material of the modified organisms will have very less diversity as they have grown with the same process and the DNA among the organisms will become similar to each other.

Hence, the correct answer is "Genetic modification decreases the genetic variation of the modified organism."

Genetically modified foods, also known as genetically engineered foods, or bioengineered foods are foods produced from organisms that have had changes introduced into their DNA using the methods of genetic engineering.

The most common GMO crops include soybean, maize, cotton, canola, and alfalfa. The following GMO crops were also planted in different countries in 2018: papaya, eggplant, potato, apple, safflower, pineapple, and sugarcane.

For centuries, farmers have bred crops for certain desirable traits. Genetically Modified (GM) crops offer improved yields, enhanced nutritional value, longer shelf life, and resistance to drought, frost, or insect pests.

Genetic modification of plants involves adding a specific stretch of DNA into the plant's genome, giving it new or different characteristics. ... The gene of interest is transferred into the bacterium and the bacterial cells then transfer the new DNA to the genome of the plant cells

GMOs have helped farmers reduce their environmental footprint by allowing them to use fewer inputs and enabling a shift to reduced tillage. These practices have led to less time spent on a tractor, less fuel used and fewer emissions.

Explanation:

Microorganisms also exist in the fossil record, but they’re rarer than other types of fossils. The most common fossils form from hard body parts, such as bones, teeth, and shells. Why do you think these fossils are more common than fossils of other soft tissues or microorganisms?

Answers

Answer:

Organisms decompose more quickly when they are in contact with oxygen. ... When an organism is buried quickly, there is less decay and the better the chance for it to be preserved. The hard parts of organisms, such as bones, shells, and teeth have a better chance of becoming fossils than do softer parts.

Explanation:

Answer:

When the decomposing process of an organism is taking place, it is breaking apart the nutrients within the organism in order to return it to the Earth in itself. When an organism buried at a quicker pace it cause the decomposing process to last at a longer time, which in term makes the chance of it being better preserved in at the same time. Due the bones of different organisms we are able to analyze the organism that has decomposed, because once that time of decomposition is complete we will be able to see the fossils of the organism and the evaluate the categorization of the specific organism that a scientist is examining.
