Answer:
Antibiotic resistance is one of the most urgent threats to the public’s health. Antibiotic resistant bacteria can cause illnesses that were once easily treatable with antibiotics to become untreatable, leading to dangerous infections. Antibiotic-resistant bacteria are often more difficult to kill and more expensive to treat.

C. genetic drift
D. gene flow
E. sexual selection
5. Ultimate source of brand new alleles in a population.
A. natural selection
B. mutation
C. genetic drift
D. gene flow
E. sexual selection
Answer:
1. D (In population genetics, gene flow is the transfer of genetic material from one population to another.)
2. C (Genetic drift may cause gene variants to disappear completely and thereby reduce genetic variation. It can also cause initially rare alleles to become much more frequent and even fixed. When there are few copies of an allele, the effect of genetic drift is larger, and when there are many copies the effect is smaller.).
3. A and also E (Individuals with inherited characteristics that allow them to best compete for limited resources will survive and have more offspring than those individuals with variations that are less able to compete. Because characteristics are inherited, these traits will be better represented in the next generation.)
4. D (Gene flow can increase fitness but if it happens in another environment, it decreases the adaptability. If alleles are advantageous, the offsprings' inheritance increases.
5. B (Mutations are the main source of alleles)

Answer:
Respiration removes oxygen from the atmosphere, and photosynthesis puts oxygen into the atmosphere.
Explanation:
Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.
Which type of isolation is being described: Yellow butterflies breed during the summer season while red butterflies breed during the winter season, because of this, they cannot interbreed
temporal isolation
geographic isolation
behavioral isolation
By stating that "Yellow butterflies breed during the summer season while red butterflies breed during the winter season" we are referencing a form of temporal isolation.
Temporal isolation is one of the limiting factors for sexual reproduction between closely related species. Temporal isolation refers to the situation in which two closely related species cannot interact sexually with one another due to the timing of their respective mating events.
The question states that the yellow butterflies will breed during the summer season, whilst the red butterflies breed during the winter. Normally, species like this are closely related enough to allow interspecies breeding to take place and create a new species or simply diversify the existing ones. However, due to the distinct timing of the breeding cycles for each butterfly, they will not be able to breed with one another, which is a prime example of temporal isolation.

1. In the overall energy transformation in photosynthesis, the energy of ____ is converted to the energy of ____.
2. In the overall energy transformation in cellular (aerobic) respiration, the energy of ____ is converted to the energy of ____.
3. In the overall energy transformation in fermentation, the energy of ____ is converted to the energy of ____.
Answer: 1. Photosynthesis converts solar energy into chemical energy that plants use to make glucose so they can grow.
2. Cellular respiration is a set of metabolic reactions and processes that take place in the cells of organisms to convert chemical energy from oxygen molecules or nutrients into adenosine triphosphate (ATP), and then release waste products.
3. Any chemical process that yields energy is known as a catabolic pathway. Cells release the energy in those organic molecules by breaking them down. Through cellular respiration and fermentation, those bonds are broken releasing the potential energy of organic molecules into kinetic energy that cells use to do work.

Analysis of _____ can be used for very precise personal identification. It is even used in anthropology to identify the bones of a deceased person.
odontology
DNA
long bone measurement
fingerprinting
Answer:
DNA
Explanation:
The DNA of a human being is very unique as each human has a different sequence of it. This allows for it to be used for very precise identification of humans such that it has been used to solve crimes.
DNA is also present in every cell in the human body which is why it is useful in anthropology as well. Anthropologists can simply extract cells from a bone and through the DNA extracted, find out more about a dead person.
Therefore, DNA is the answer.

why do stem get modified give any three examples and explain how this notification help the plant
Answer:
underground stem -- for storage of food ex. potato , ginger.
spines for protection ex. citrus , bougainvillea
Explanation:
Rhizomes and corms are underground stems, modified for the storage of food. Also, these stems help in vegetative reproduction of these plants. The tips of the underground stem in potato plants become swollen due to the accumulation of food. The potato is a tuber that helps in the storage of food and bears eyes on it.
Tell the story of the predator/prey loop.
If the owl population goes up, then ...
Answer:
Below : )
Explanation:
Well, in most cases if the predator population rises most likely the prey population decreases this is because there is a big population of the predator which allows more of them to eat the prey so the prey decreases. Now when the prey decreases this again affects the predators because now the predators are limited to food so that causes many of them to decrease.
In this scenario, if the owl is the predator, as the population rises, its prey will decrease.
If the owl is the prey, the predators would most likely increase.

Which of the following occurs when the moon is closest to the Earth?
periapsis
apogee
revolution
ellipse
Answer:
periapsis
Explanation:
Periapsis is the point when the orbiting object comes the closest to the thing it is orbiting around; for example, the moon is at periapsis when it is closest to the Earth.
Moon revolves around the earth in an elliptical pathway. At some point moon approaches earth at its closest point. This point is called perigee. This closest approach is called periapsis.
What is periapsis?Moon is the only satellite of earth. Moon revolves around earth along with rotating about its own axis. Earth have a gravitational pull into moon and this force will be different at different point of orbital revolution.
Moon's orbit is elliptical. The points of farthest approach to earth is called apogee and the closest point is called perigee. Every planet will have an apogee and perigee with sun as for earth and also with their satellites.
The farthest approach of moon from the earth is called apoapsis and the closest approach is called periapsis. Periapsis is also called perilunar, parselene, perilunar etc. Hence, option A is correct.

The figure shows two water molecules held together by a/an
bond. (arrow tip)
A. covalent
B.hydrogen
C.ionic
D.van der Waals
Answer:
b) Hydrogen
Explanation:
The figure shows the hydrogen bonding of two H2O molecules. The red atom is Oxygen which is δ−, and the white atom is Hydrogen which is δ+, this is determined by their electronegativity. H2O molecules can form hydrogen bonding when the Hydrogen atom bonds through hydrogen bonding to the oxygen atom and vice versa.
This type of bond is an intermolecular bond
