What is the theory of natural selection, and why does it occur in an organism? Give an example.

Answers

Answer 1

Answer:

It occurs in organisms because an organism with a beneficial trait/mutation have a higher chnace of surviving compared to organisms that do not. So the organsims that do survive pass on their genes to the next generation, and the bext generation will pass on those genes to the generation after and so on. But all the organisms that do not possess a beneficial trait/mutations will not survive, therefore they cannot reproduce and pass on those genes to their offspring. This means that most of the population will posses that trait/mutation.

Example: Spotted moths camouflage with bark so they are seen by predators and eaten. Black moths are easily seen by predators and are eaten. Spotted moths then pass on their genes to the next generation of moths.

4. A wave traveling at 200 m/sec has a wavelength of 2 meters. What is the
frequency of this wave?

Answers

Given that,

The speed of a wave, v = 200 m/s

Wavelength, [tex]\lambda=2\ m[/tex]

We need to find the frequency of this wave. The relation between wavelength, frequency and the speed is given by :

[tex]v=f\lambda\\\\f=\dfrac{v}{\lambda}\\\\f=\dfrac{200\ m/s}{2\ m}\\\\f=100\ Hz[/tex]

So, the frequency of this wave is 100 Hz.

If you assume that the high projection is correct, what is one way the larger
human population can ensure it has enough food?

Answers

Planting fruit and vegetables

The one way the larger human population can ensure it has enough food is by finding more efficient ways of growing crops. Therefore, the correct option is option B.

What is population?

The term "population" is frequently used to describe the total number of people living in a particular location. To estimate the number of the residents within a certain territory, governments conduct censuses. The phrase has particular use in the domains of ecology and genetics and is also used to refer to plants, animals, and microbes.

An region with a sexual populace is one in which interbreeding between any two individuals therein is both conceivable and more likely than cross-breeding between individuals from other places. The one way the larger human population can ensure it has enough food is by finding more efficient ways of growing crops.

Therefore, the correct option is option B.

To make ethanol for use in _______, yeast is provided with sugars that have come from crops such as maize.

Answers

Answer: To make ethanol for use in BIOETHANOL( a biofuel), yeast is provided with sugars that have come from crops such as maize.

Explanation:

Ethanol Fermentation is defined as the process whereby sugar( fructose, sucrose or glucose) are broken down by the action of microorganism such as yeast to give of ethanol(alcohol) and carbondioxide as by products.

In the use of ethanol as a biofuel, there are different sources where sugar products can be gotten from, but the main sources of sugar required to produce ethanol come from energy crops. These crops are grown specifically for energy use and include corn, maize and wheat crops.

BIOETHANOL is a renewable source of fuel that can be produced through the yeast fermentation of sugar gotten from crops such as maize. Although ethanol can be used in wine and beer production, sugar sources are usually gotten from grape fruits and barley.

Which type of mutation often has the least effect on organisms' traits (and may have no effect at all)? Nondisjunction Substitution Insertion Deletion

Answers

Answer:

The correct answer is - substitution.

Explanation:

Substitution mutations are the point mutations that are the mutations that least likely affect the trait of an organism or have no effect at all. Substitution mutations take place when there is only one nucleotide base is substituted by another nucleotide base in the  DNA or RNA of an organism's genome.

In this case, there is no effect found on the protein formed by these DNA sequences. These substitution mutations generally found in somatic cells and have little to no effect at all.

what could the melting of glaciers cause? the answers are a- more fresh water b- calmer weather c- coastal flooding d- an increase in the birth rate​

Answers

Answer:

it's mostly caused by unhealthy gases in the air such as greenhouse gases and carbon dioxide. however, it could possibly be c or a.

Explanation:

Answer:

C. Coastal Flooding

Because:

Birth rate has nothing to do with this, so we can eliminate that

Calmer Weather doesn’t depend on glaciers, so we can eliminate that

More fresh water does seem to make sense, but glaciers would melt into the ocean, and the ocean is salt water, so that fresh water wouldn’t be fresh water anymore

Coastal Flooding is correct because glaciers hold tons of water and if they melted, so much water would be released that it would definitely cause coastal flooding
