Based on Darwin's ideas of descent with modification and natural selection, which observation would best support the idea that
increased competition causes changes in a species?
A) A population of frogs develop greener skin after a hurricane blows away the white flowers in the environment
B) A population of artic foxes develop a brown fur color as warmer temperatures reduce the number of days of
snowfall in the area
C) A population of rattlesnake goes extinct as the water resources in their environment dry up during an
extreme, prolonged drought
D) A population of deer show an increase in antler size over time, which allows them to obtain more mates
during mating season
Answer:
D) A population of deer show an increase in antler size over time, which allows them to obtain more mates during mating season
Based on Darwin's ideas, a population of deer show an increase in antler size over time, which allows them to obtain more mates during mating season (Option D).
What is evolution?According to Darwin, evolution can be defined as descendence with modification, which mainly occurs via natural selection.
Natural selection can be defined as the differential survival and reproduction of the fittest organisms.In this case, intraspecific competition favors deers more adapted to reproduce in the population.In conclusion, based on Darwin's ideas, a population of deer show an increase in antler size over time, which allows them to obtain more mates during mating season (Option D).

Explanation:
You observe every fall that the trees in the forest lose their leaves, but by the following fall, the leaves have disappeared. The most accurate explanation for this observation would be:
The tree creates a layer known as the abscission layer, which prevents nutrients and water from reaching the tree and inhibits the growth of the leaves. Hormones in the trees cause the process of abscission.
What is abscission layer?Tiny tubules in the abscission layer are responsible for carrying carbohydrates back into the tree and delivering water to the leaf, flower, or fruit.
The amount of nutrients and water that pass through the tubes is decreased in the autumn because cells in the abscission start to expand and exude a waxy substance.
Abscission of leaves, which takes place in the fall, is the natural loss of an old leaf at the base of the petiole. Many physical and biochemical changes occur during leaf abscission, most of which are controlled by plant hormones.
Therefore, every fall that the trees in the forest lose their leaves.

g Two linked genes, (A) and (B), are separated by 18 centiMorgans. A man with genotype Aa Bb marries a woman who is aa bb. The man's father was AA BB. What is the probability that their first child will both be ab/ab
Answer:
The probability that their first child will both be ab/ab = 41%.
Explanation:
Available data:
Two linked genes (A) and (B) ⇒ 18 centiMorgans apartMan ⇒ Aa BbMan´s father ⇒ AA BBWoman ⇒ aabbThe recombination frequency is given by the distance between genes. We have to know that 1% of recombinations = 1 map unit = 1cm.
Recombination frequency = 0.18
Man: AaBb
Gametes) AB Parental
ab Parental
Ab Recombinant
aB recombinant
18 centi morgan = 18 % of recombination in total
= % aB + % Ab
= 9% aB + 9% Ab
100% - 18% = 82% of parental in total
= % of AB + % ab
= 41% AB + 41% ab
The frequency for each gamete is:
AB 41%
ab 41%
Ab 9%
aB 9%
Cross: man x woman
Parental) AaBb x aabb
Gametes) AB, Ab, aB, ab ab, ab, ab, ab
Punnett square) AB ( 41%) Ab (9%) aB (9%) ab (41%)
ab AaBb Aabb aaBb aabb
ab AaBb Aabb aaBb aabb
ab AaBb Aabb aaBb aabb
ab AaBb Aabb aaBb aabb
F1) 41% of the progeny is expected to be AaBb

25.0
241
216
Answer: See explanation
Explanation:
Your question isn't complete as you didn't attach the chart.
The weight on the Moon of an individual is 16.5% of the person's weight on Earth. For example, if one weighs 100kg on Earth, then the person will weigh 16.5kg on the moon.
Based on the question, since the person's weight on Earth is 130 pounds, then the weight on the moon will be:
= 16.5% × 130pounds
= 0.165 × 130 pounds.
= 21.45 pounds
The closest answer to this is 21.6 pounds

Answer:
A single replacement reaction occurs when an element reacts with a compound to produce a new element and a new compound. It can only occur when the element that is doing the replacing is more reactive than the element that is being replaced. Therefore, it is useful to have a list of elements in order of their relative reactivities. The activity series is a list of elements in decreasing the order of reactivity. Since metals replace other metals, while nonmetals replace other nonmetals, they each have a separate activity series.
There are two types of single replacement reactions:
A metal replaces another metal that is in solution:
A + BC → B + AC
Example: Zn + CuC[tex]l_{2}[/tex] → Cu + ZnC
A halogen replaces another halogen that is in solution:
A + BC → C + BA
Example: Br[tex]_{2}[/tex] + 2KI → I

2. Complete the following chart about the three main research projects
that led to the identification of DNA as the genetic material.
RESEARCHERS' NAMES
SUMMARY OF RESEARCH
SUMMARY OF CONCLUSIONS
Griffith
found a "transforming principle"
Avery
Hershey and Chase
identified the substance that phages inject
into bacteria
Answer:
Griffith's experiment, reported in 1928 by Frederick Griffith, was the first experiment suggesting that bacteria are capable of transferring genetic information through a process known as transformation. Griffith's findings were followed by research in the late 1930s and early 40s that isolated DNA as the material that communicated this genetic information.
Griffith's experiment discovering the "transforming principle" in pneumococcus bacteria.
Pneumonia was a serious cause of death in the wake of the post-WWI Spanish influenza pandemic, and Griffith was studying the possibility of creating a vaccine. Griffith used two strains of pneumococcus (Streptococcus pneumoniae) bacteria which infect mice – a type III-S (smooth) which was virulent, and a type II-R (rough) strain which was nonvirulent. The III-S strain synthesized a polysaccharide capsule that protected itself from the host's immune system, resulting in the death of the host, while the II-R strain did not have that protective capsule and was defeated by the host's immune system. A German bacteriologist, Fred Neufeld, had discovered the three pneumococcal types (Types I, II, and III) and discovered the quellung reaction to identify them in vitro. Until Griffith's experiment, bacteriologists believed that the types were fixed and unchangeable, from one generation to another.
In this experiment, bacteria from the III-S strain were killed by heat, and their remains were added to II-R strain bacteria. While neither alone harmed the mice, the combination was able to kill its host. Griffith was also able to isolate both live II-R and live III-S strains of pneumococcus from the blood of these dead mice. Griffith concluded that the type II-R had been "transformed" into the lethal III-S strain by a "transforming principle" that was somehow part of the dead III-S strain bacteria.
Completing the attached chart about the three main research projects ;
Griffith summary of research : Identified what R-strain bacteria took up from heat-killed S bacteria,Avery summary of research : Identified protein as not the transforming factorAvery summary of conclusion : Found a " transforming principle "Hershey and chase summary of conclusions : Found the " Infection and replication principle "All three researches were carried out to discover the genetic material ( DNA ) which is responsible for the transfer of genetic traits from parent cells to daughter cells.
Griffith research shows that bacterias can get there DNA ( genetic material ) through a process known as transformation and the experiment to prove this research was carried out by killing S bacterias through heat and then adding them to R-strain bacteria. Griffith observed and concluded that the Genetic materials of the S bacteria was taken up by the S -bacterias through a process known as " transforming principle "
During Avery research for the genetic material ( DNA ) Avery treated a mixture with DNA-destroying enzymes to see if the colonies of the mixture will transform but they failed to transform which proves that proteins are not the transforming factors and that DNA is the genetic material.
Hence we can conclude that Completing the attached chart about the three main research projects is as written above.

Paul Plutonian and Penelope Phobos also met online. Both of them are
heterozygous for their tall head, which is dominant over a short head.
Create a Punnett Square to show the possibilities that would result if Paul
and Penelope had children. (Hint: Read question 5.)
A. List the possible genotypes and phenotypes for their children.
B. What are the chances of a child with a tall head?
C. What are the chances of a child with a short head?
Answer:
A. HH - tall head, Hh - tall head, hh - short head
B. 75% or 3/4
C. 25% or 1/4
Explanation:
Paul and Penelope are heterozygous for their tall head, which means they have one dominant and one recessive allele. So, their genotype is Hh.
When crossed, the results are 1 HH - h0m0zygous dominant tall head, 2 Hh - heterozygous tall head, and 1 hh - h0m0zygous recessive short head.
So, there is a 75% of a child with a tall head and a 25% chance of a child with a short head.
Hope that helps.
A white blood cell (WBC) encounters bacteria in a scrape on the knee of a child who has fallen off of his bicycle. The WBC’s job is to take the bacteria inside of itself and destroy the bacteria. If the bacteria cannot be moved across the WBC membrane, how will the WBC most likely take it in?
Answer:
The correct answer is - phagocytosis.
Explanation:
Phagocytosis is a type of endocytosis that also engulfs the solid material including microbial pathogens like bacteria and others. In immunity response macrophages, neutrophils and. immature dendritic cells are white blood cells that perform the phagocytosis process to kill the microbes and antigens.
Phagocytosis ingests and digest pathogens and develops an adaptive immune response an essential part of the innate immune system. WBC will most likely take it in through phagocytosis in the given case.
