The graphs here show the distribution of beak depths for the ground
finches on Daphne Major, an island in the Galapagos. The bird beaks were
measured over a multi-year study, including a time period before and after
a drought. The drought reduced the supply of seeds and left most of the
seeds as thick-walled nuts that survived the drought. Analyze the data and
select the claim about natural selection and genetic diversity that is
supported by the data.

Natural selection tends to reduce genetic variation, as there was a smaller distribution
of beak depths, but it tends to select for the most fit phenotypes, as there was an
increase in average beak depth after the drought.

Natural selection tends to increase genetic variation, as there were more ground
finches after the drought, and it tends to select for the most fit phenotypes, as there
was an increase in average beak depth after the drought.

Natural selection tends to reduce genetic variation, as there was a smaller distribution
of beak depths, but it tends to select against the most fit phenotypes, as there was an
increase in average beak depth after the drought.

Natural selection tends to increase genetic variation, as the average beak size
increased after the drought, but it tends to select against the most fit phenotypes, as
there was a decrease in population size for the finches after the drought

Answers

Answer 1

Answer: (A) Natural selection tend to reduce genetic variation as there was a smaller distribution of beak depths, but it tends to select for the most fit phenotypes, as there was an increase in average beak depth after the drought.

Explanation: The picture below shows proof if needed. On USATP

The Graphs Here Show The Distribution Of Beak Depths For The Groundfinches On Daphne Major, An Island
Answer 2

Natural selection tend to reduce genetic variation as a smaller allocation of beak depths, but it tends to select for the most fit phenotypes, as an increase in average beak depth after the drought.

How does natural selection affect genetic variation?

Genetic variations that vary gene and protein role.

If a trait is favourable and helps the someone survive and breed, the genetic variation is more likely to be passed to the next generation.

Thus, option "A" is correct by selecting for or against a specific gene.

Why are ferns and mosses poorly adapted to a terrestrial life​

Answers

Answer:

Because they require a WATER medium for reproduction

Explanation:

Ferns are a group of living organisms under the division; Pteridophyta while mosses belong to the group Bryophyta. Mosses are considered primitive and non-vascular plants because they lack true stems, leaves and roots or vascular tissues. while ferns possess these organs, hence, are said to be vascular.

However, ferns and mosses are poorly adapted to a terrestrial life i.e. life on land because they both require a water medium for their motile male gametes to swim and fertilize their eggs (female gametes).

Explanation:

the potential for antibiotic resistance was recognized in the early 1940s, almost immediately after the first large-scale clinical use of penicillin, the first antibiotic. mass production of penicillin was part of the war effort of world war ii, when the drug was used widely by military populations to treat the wounded. however, even before the war had ended, resistance to penicillin was already being reported. in 1940, british biochemists sir ernst boris chain and sir edward penley abraham published a report about a bacterial enzyme capable of destroying penicillin. in the following decades, overuse and repeated exposure to antibiotic agents favored the selection and replication of numerous strains of antibiotic-resistant bacteria. select all of the statements that accurately portray the role of natural selection in antibiotic resistance. a) when bacteria are repeatedly exposed to antibiotics, they learn how to avoid the antibiotic and survive to reproduce. b) when people overuse antibiotics, the bacteria get resistant to the antibiotic and it is no longer an effective treatment. some bacteria possess a gene for bacterial resistance. these bacteria are likely to survive a course or antibiotics and reproduce. 09 d) bacteria containing the gene for antibiotic resistance can share a plasmid of the gene with other bacteria, allowing the population of bacteria with antibiotic resistance to survive and reproduce. when someone quits taking an antibiotic when they are feeling better, they likely kill only the weaker bacteria. the bacteria with a gene for antibiotic resistance survive, giving them the opportunity to reproduce. e

c) some bacteria possess a gene for bacterial resistance. these bacteria are likely to survive a course or antibiotics and reproduce.

d) bacteria containing the gene for antibiotic resistance can share a plasmid of the gene with other bacteria, allowing the population of bacteria with antibiotic resistance to survive and reproduce

e) when someone quits taking an antibiotic when they are feeling better, they likely kill only the weaker bacteria. the bacteria with a gene for antibiotic resistance survive, giving them the opportunity to reproduce

Explanation:

When bacteria are initially exposed to an antibiotic, those most susceptible to the antibiotic will die quickly, leaving any surviving bacteria to pass on their resistant features to succeeding generations.

As in option C , bacteria possessing better gene will b selected by the nature and hence portrays Natural selection

In option d Bacteria reproduce by plasmid (extra chromosomal DNA ) transfer . Bacteria with antibiotic resistant gene with pass these genes to the succeeding generations.

When bacteria are initially exposed to an antibiotic, those most susceptible to the antibiotic will die quickly, leaving  bacteria possessing gene resistant against antibiotics. Here, Darwin’s theory of natural selection comes in. This gives the bacteria an advantage over other(which do not possess antibiotic resistant gene) this bacteria will grow better than its neighbors and can increase in numbers

In option e When one quits antibiotics before completing the entire course of any prescribed antibiotic. The antibiotic   resistant bacteria survives. Bacteria that are not controlled or killed by antibiotics. They are able to survive and even multiply in the presence of an antibiotic.

The release of the enzyme amylase into the pancreatic duct so that it can break down starches is B. the breakdown of glucose in the chloroplast. Thus, option "B" is correct.

How does glucose break down in human beings?

Salivary amylase starts the digestion of starch. Around 30% of total starch is digested by salivary amylase into maltose in the mouth. Pancreatic juice also has an amylase enzyme which digests the remaining starch into disaccharides in the small intestine.

The power in our homes and buildings cycles at a frequency of 60Hz. If someone accidentally dropped a power line into a holding tank for frogs their muscles would immediately become stiff. This is because the high frequency stimuli is causing:_______

a. rigor mortis.
b. tetanus.
c. fatigue.

Answers

Answer:

a. rigor mortis.

Explanation:

Electricity refers to the power generated from various power sources or power plants such as hydroelectric, wind turbine, solar, nuclear, etc.

Generally, the power supplied to homes, offices and buildings cycles at a frequency of 60 Hertz or 50 Hertz depending on the parameters chosen in countries. If a power line is dropped accidentally into a holding tank for frogs, it would immediately cause their muscles to become stiff due to the current flowing through the power line i.e because the power line is energized and has electrons moving across its terminals. This stiffness is because the high frequency stimuli is causing rigor mortis.

What is natural selection?

Natural selection is a mechanism of evolution that occurs when individuals with certain advantageous traits are more likely to survive and reproduce, passing those traits on to their offspring. This process leads to a gradual change in the genetic makeup of a population over time, as beneficial traits become more common and less advantageous traits become less common.

Natural selection occurs because resources in nature are limited, leading to competition for survival and reproduction. The individuals with traits that best suit them to their environment will have a higher chance of success, while those with less suitable traits are more likely to die or fail to reproduce. Natural selection is a key driver of evolution and is responsible for the diversity of life on Earth.
