A large population of houseflies was sprayed with a newly developed, fast-acting insecticide. the appearance of some houseflies that are resistant to this insecticide supports the concept that
Final answer:
The presence of insecticide-resistant houseflies illustrates the concept of pesticide resistance and microevolution, where selective pressure from the use of pesticides leads to the survival and reproduction of resistant individuals, causing resistance to increase within the population over time.
Explanation:
The appearance of some houseflies that are resistant to a newly developed insecticide supports the concept of pesticide resistance and is an example of microevolution. This happens when a population of insects is subjected to a selective pressure, such as a chemical pesticide, and the few individuals that by chance carry genes that confer resistance to the insecticide are more likely to survive and reproduce.
Over time, these resistant genes are passed on to the offspring, and the resistance trait becomes more common in the population. Eventually, this could lead to the pesticide becoming ineffective, requiring higher doses or the development of a new pesticide. This cycle of development of insect resistance is a significant challenge in managing pest populations and has been observed since the usage of DDT in the 1940s.
Conservationists establish that the minimal viable population of a population of tigers in an extensive geographical area is 16. The current population of tigers is 10. What is likely to happen to the population of tigers?
A.
Tigers from adjoining populations will immigrate into the geographical area of this population.
B.
The tiger population will grow to 16 and then become stable, staying around this figure.
C.
The tigers will die out because they will be unable to sustain their population.
D.
The lifespan of the population of tigers will increase because of less competition.
Answer:
C.
The tigers will die out because they will be unable to sustain their population.
Explanation:
Conservationists establish that the minimal viable population of a population of tigers in an extensive geographical area is 16. Given that the current population of tigers is 10, which is lower than the minimal viable population of the tigers, the tigers are more likely to die out because they will be unable to sustain their population.
Answer:
C. The tigers will die out because they will be unable to sustain their population.
Explanation:
Minimal viable population is the lowest number of a species required to survive in a wild habitat. Because this population of tigers (10) is below the minimal viable population of 16, the population is unlikely to be able to sustain their population and therefore is likely to die out.

Explanation:
Succulent plants such as aloes are known for their thick stems and leaves, which allow them to store water. Which statement best explains how succulents' thick stems and leaves evolved through natural selection?
A. Thick stems and leaves were selected because succulents need to consume a large supply of water every day.
B. Thick stems and leaves were selected because they help succulents take up more space, which in turn helps them capture more sunlight.
C. Thick stems and leaves were selected because they guarantee that young succulents already have all the water they will need for the rest of their lives.
D. Thick stems and leaves were selected because succulents with these characteristics are more likely to survive hot, dry weather and, thus, produce more offspring.
Answer:
D. Thick stems and leaves were selected because succulents with these characteristics are more likely to survive hot, dry weather and, thus, produce more offspring
Explanation:
The succulents have not always been as they are now, but they have evolved from plants that looked different and existed in different weather conditions. As the environment has been changing, in order to survive, the succulents started to develop traits that would be advantageous for them to survive in the hot and dry weather. The succulents that started to develop such traits, like the thick stem and leaves were the ones selected to survive, as they were the ones that had the advantage in this type of environment. The thick stems and leaves enabled them to store as much water as possible when there is, and also to preserve it for long periods of time, while the succulents that didn't possessed this traits died out because they were not able to sustain the new conditions, nor to be able to reproduce effectively.

Plants which produce their gametes in flowers are called: I know it's not gymnosperms. So which one is it?
angiosperms
vascular
antheridium
gymnosperms
Answer:
Plants which produce their gametes in flowers are called angiosperms.( first choice)
Plants that produce gametes in flowers are known as angiosperms, which include a wide range of plants such as herbs, shrubs, and most trees, and are characterized by having seeds within the ovaries of flowers.
Explanation:Plants which produce their gametes in flowers are called angiosperms. Unlike gymnosperms, which produce seeds in cones, angiosperms produce seeds within the ovaries of flowers. After fertilization, the walls of the ovary thicken and often develop into fruit, aiding in seed dispersal.
Angiosperms include a vast array of plants including grasses, herbs, shrubs, and most deciduous trees. The main parts of a flower are the sepals and petals, which protect the reproductive organs, such as the stamens that produce the male gametes (pollen grains) and the carpels that contain the female gametes (eggs within the ovules).

1. In what type of ecosystem can this population be found?
2. How might this population suddenly increase? How might this affect the ecosystem
3. What might happen to the ecosystem if this population were removed?
Answer:
1) The ecosystem would have the abiotic factors of low precipitation, dry winds, and low temperatures. The biotic factors would include the animals living with the penguins such as polar bears and yaks.
2) The population would suddenly increase if either the penguin's predators had a drop in numbers or if the penguin's food source became more readily available. This growth in population would result in food becoming harder to find and predators once again growing in numbers. This would eventually cause the penguin population to shrink once more.
3) Predators would die out. Whatever organism(s) were the penguin's food source would grow in size exponentially. Other animals may suffer a drop in numbers if the penguin's predators choose to prey on them.

Monkeys and humans share many of the same DNA sequences and have similar proteins, indicating that a) the two groups belong to the same specie b) the two groups share a relatively recent common ancestor c) the two groups first appeared on Earth at about the same time d) monkeys evolved from humans
Answer:
B
Explanation:
If two creatures share the same DNA traits, this means that they have a common ancestor, whether it be recent, or distant.
We know for a fact, that Monkeys did not evolve from humans, due to the fact they came first. Humans highly likely evolved from monkeys, so we may be considered the same, but genetically we are not.
That rules out all other answers besides B.
Hope this helped! :)
The significant overlap in DNA and proteins between monkeys and humans points to a relatively recent common ancestor, but it does not mean they are the same species, evolved from each other, or appeared on Earth at the same time.
Explanation:The similarities in DNA sequences and proteins shared between monkeys and humans suggest that these two groups share a relatively recent common ancestor. This doesn't mean they belong to the same species or that monkeys evolved from humans. It also doesn't imply they first appeared on Earth at the same time. It means that they have a common ancestor from which both species have evolved, separately, into the distinct creatures they are today. This ancestor lived far more recently than the ancestors we share with less closely related Biological groups.

Water makes up a large percentage of the body’s cells. For a cell to remain in homeostasis, there must be a mechanism to control water changes in the cells. The movement of water from an area of high water concentration to an area of low water concentration is
Answer:
The movement of water from an area of high water concentration to an area of low water concentration is called OSMOSIS.
Explanation:
Osmosis is the process by which water molecules moves from a region of high water concentration to the region of low water concentration via a selectively permeable membrane.
In living cells, water moves across boundaries through the process of osmosis, that is cells gain or lose water through osmosis. The direction of movement of water depends on the concentration of the solutes on either side of the selective membrane, water usually moves in the direction of low water concentration and high solute concentration. For instance, for two solute concentrations of 50 M and 70 M, water will move away from 50 M and flow into 70 M
In osmosis, the net movement of water continues until the concentrations on both side of the selective membrane is the same.
Several bird species feed in a certain species of tree. Each bird species feeds
in a different part of the tree. Which statement is true of these bird species?
A. They have adapted to different niches due to competition
B. They have a carnivorous relationship with the tree species.
C. They have adapted to different niches due to predation
D. They have a symbiotic relationship with the tree species.
Answer:
A. They have adapted to different niches due to competition
Explanation:
If several bird species feed on a certain tree species, these birds will establish a strong competition with each other for food. One result of this competition will be that each species will look for a part of the plant to feed on, probably each species will choose the part of the plant where it will be easier to beat the competition for food. Based on this, we can conclude that the correct answer is "They have adapted to different niches due to competition."
Final answer:
Bird species feeding in different parts of a tree have a) adapted to unique niches to avoid competition, leading to the development of specialized traits and allowing for coexistence without direct competition for resources.
Explanation:
Based on the information provided, multiple bird species feeding in different parts of the same tree species have adapted to different niche due to competition. This differentiation of niches allows species to coexist without direct competition for resources, which can be a driving force behind the development of specialized traits, such as distinctive beak shapes. The fact that different bird species have evolved to utilize various parts of the tree and consume different food sources indicates that they have adapted to different niches due to competition, which aligns with option A. They have not necessarily formed a carnivorous or symbiotic relationship with the tree, nor is their niche adaptation primarily driven by predation.

The Milky Way is held together by a black hole's gravitational force. Since the stars near this black hole move at a high speed, what can you infer about the black hole? A. Its location B. Its depth C. Its speed D. Its size
Answer:
A. Location
Explanation:
A black hole is a massive structure in the space from which light cannot escape. Therefore, the depth of the black hole (B), the speed (C), and size (D) are extremely difficult to measure. However, scientists have been able to locate the position of black holes via the movement of stars and gases around it. Typically, since black holes are extremely dense objects, masses spins around the black holes and form a structure called an accretion disk. By looking at the speed of stars, the scientists can detect where the black holes are in the space.
Answer:
A. Its location
Explanation:
Semipermeable membrane that borders the cell
Answer:
Cell membrane or Plasma membrane
Explanation:
The cell membrane is also known as the plasma membrane. It is the outer covering of the cell that is semi-permeable. It serves as a barrier that protects the internal parts of the cell from the outside environment. It is semi-permeable as it allows certain substances to pass through, but keeps others out. It also allows certain substances to exit the cell.

Why are new stars likely to form in irregular galaxies? A. They contain large amounts of gas and dust. B. They're part of the Local Group. C. They don't have regular shapes. D. They contain many black holes.
Please help :)
Answer:
A. They contain large amounts of gas and dust.
Explanation:
Having a lot of gas and dust means that these galaxies have a lot of star formation going on within them. This can make them very bright.
Answer:
The correct answer is option A, that is, they contain large amounts of gas and dust.
Explanation:
A galaxy, which does not exhibit a distinguished regular shape, like an elliptical or a spiral galaxy is considered as an irregular galaxy. The irregular galaxies may comprise enormous concentrations of dust and gas.
The stars have the possibility to get formed in the irregular galaxies as they seem to exhibit huge concentrations of gas and dust, which is an essential criterion for the formation of new stars to take place.
