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?
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?
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.
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
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.

2.salinity differences between water masses
3.pressure differences between water masses
4.Ekman spiral
Answer:
its the ekman spiral not pressure differences between water masses
Explanation:
Upwelling. Along some coasts, the Ekman spiral causes an upwelling of deeper water to replace the water that has moved offshore. The colder, deeper water is richer in nutrients. These upwelling areas contain some of the richest fishing grounds in the world.

How can evolutionary relationships be modeled and interpreted?
Answer:
Scientists must collect accurate information that allows them to make evolutionary connections among organisms. Similar to detective work, scientists must use evidence to uncover the facts. In the case of phylogeny, evolutionary investigations focus on two types of evidence: morphologic (form and function) and genetic.
