Answer:
Sex evolved as an extremely efficient mechanism for producing variation, and this had the major advantage of enabling organisms to adapt to changing environments. Sex did, however, come with a cost. In reproducing asexually, no time nor energy needs to be expended in choosing a mate.

What is the name of the gradient between high pressure and low pressure?
Answer:
Pressure gradient
Explanation:
Hope this helps :)
Answer:
Pressure gradient
Explanation:
The change in pressure measured across a given distance is called a "pressure gradient". The pressure gradient results in a net force that is directed from high to low pressure and this force is called the "pressure gradient force". The pressure gradient force is responsible for triggering the initial movement of air

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.)
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.

DNA replication occurs to prepare the cell for
a. growth
b. cell death
c. protection against pathogens

D - Cell Division
Explanation:
This is because the DNA needs to be replicated in order for the cells to be able to divide and create new daughter cells.
White tailed deer begin their reproductive cycle in the fall. Rising testosterone levels in
male white tailed deer cause them to start their breeding season around the same
time. Offspring are born the following spring and summer.
What is the most likely explanation for the white-tailed deer having a seasonal
breeding cycle instead of a monthly breeding cycle?
The explanation for the white-tailed deer having a seasonal breeding cycle should be that deer provide birth in the spring and summer.
What is seasonal breeding?It is considered to be animal species so it should be successfully mated at the time of specific times of the year. It permits the optimization of survival of young because of factors like food, water availability, etc
So, here deer provide birth in the spring and summer for avoiding the pregnancy at the time of hot summer months.

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

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.
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.
