2. Natural selection is an example of a mechanism of
evolution. Does this mechanism produce a change in
individuals or populations? Explain!

Answers

Answer:

Populations

Explanation:

It cannot change individuals. This is because it happens over many generations. E.g. Peppered moths camouflage with bark. Black moths do not, so they are easily seen by predators. The black moths are eaten because they do not have a desirable trait for survival. The black moths cannot then pass on the trait for black wings to their offspring. However, the peppered moths can pass on their trait for peppered wings to their offspring. Overtime, the population of black moths will decrease and most of the population will have peppered wings. The trait for peppered moths will be present even after many generations and black moths will be rare.

D

Weather can change quickly, but climate changes slowly.


E

Weather is all around us. It is what happens from minute to minute. Rain and snow are examples of weather. Climate, on the other hand, is quite different. Climate is the pattern of weather experienced over a long period of time in a certain area. A region that has high temperatures over many years has hot climate. Knowing the weather can help you choose what to wear today. Knowing the climate can help a farmer choose what crops to plant.

Answers

Answer:

B . Knowing the climate makes it easy to predict the weather.

C . If it is cold today, you almost certainly live in a cold climate.

D . Weather can change quickly, but climate changes slowly.

Explanation:

If we know the climate of a particular region we can predict the weather of the next day or week of that region because climate is remain the same of a specific region. If the weather is cold it means that you live in a cold climate, similarly, if the weather is warm it means the climate of that region is warm and hot. Weather can change and has high variations whereas climate is the average atmospheric conditions of a region for a long period of time.

Which step happens first in DNA replication?

Answers

Answer:

Initiation

Explanation:

The initiation of DNA replication occurs in two steps. First, a so-called initiator protein unwinds a short stretch of the DNA double helix. Then, a protein known as helicase attaches to and breaks apart the hydrogen bonds between the bases on the DNA strands, thereby pulling apart the two strands. As the helicase moves along the DNA molecule, it continues breaking these hydrogen bonds and separating the two polynucleotide chains (Figure 1).

B. People enter the coffee shop at the same rate as others leave.

Explanation:

did the test !!

The answer is B. People enter the coffee shop at the same rate as others leave.

In a reaction in dynamic equilibrium, the forward and reverse reactions occur at the same rate, meaning that the concentrations of reactants and products remain constant over time.

Similarly, in the coffee shop scenario, if people are entering and leaving at the same rate, the number of customers inside the shop will remain constant, just like the concentrations of reactants and products in equilibrium.

In the field of medicine, researchers have recently designed a technique that allows them to use adult
stem cells to test the potency and safety of newly designed drugs for humans. What is the most
likely advantage of this new technology compared with other forms of drug trials?
A
It helps ensure that the shelf life of newly designed drugs is as long as possible.
B
It helps ensure that the newly designed drugs can cure all patients they are used to treat.
C
It helps reduce the demand to test newly designed drugs on animals.
D
It helps reduce the time it takes to bring newly designed drugs to the market.

Answers

Answer:

The answer is B

Explanation:

The technique that allows them to use stem cells to test the potency and safety of newly designed drugs for humans, helps reduce the time needed to bring newly designed drugs to market.

The stem cells to test newly designed drugs for humans

Use important stem cells to define the toxicity of new drugs presented results in preliminary tests. The rational use and search for alternative methods to the use of animals in scientific research is currently a worldwide concern. However, despite the stages of the scientific community, it is still not possible to open animal experimentation in the so-called pre-clinical development of new drugs and other products for human health.

With this information, we can conclude that the technique that allows them to use stem cells to test the potency and safety of newly designed drugs for humans, helps reduce the time needed to bring newly designed drugs to market.

1. The colour of a tomato can be represented by RR, Rr or rr. Why do we use capital
letters for some symbols and lower case letters for others? Why are there two
symbols for one trait (characteristic)?

Answers

Answer:

The capital letter is used to show a dominant trait, while a lowercase is used to represent a recessive trait.

Explanation:

If you are to take a Mother and a Father as example, and they have 3 children, the father's brown eyes as example we can show the children with capital and lower case depending on their looks. If the Father had brown eyes and 2 of his children out of 3 have brown eyes, we can represent that as a dominant trait, so it would be R. Then, if we take the father's hair color, brown, and the mothers hair color, blonde, we can say 2 of 3 children have brown hair, so 1 of 3 children have brown hair. So we now know that brown hair is a recessive trait. 2 of 3 children have blonde hair so the child with brown eyes and blonde hair could be represented like "Rr". Hope that helps, this is just my little explanation of this!
