Describe and account for the relationship between the two population growth curves between hares and lynx.
Answer:
The lynx's principal food source is the snowshoe hare. These two species' population cycles are intertwined. When hares are abundant, lynx consume almost nothing else and kill two hares every three days. When hares are sparse, lynx eat mice, voles, squirrels, grouse, ptarmigan, and carrion.

What is a similarity between a plant's response to light and to gravity?
Answer:
Plants respond directly to Earth's gravitational attraction, and also to light. Stems grow upward, or away from the center of Earth, and towards light. Roots grow downward, or towards the center of Earth, and away from light. These responses to external stimuli are called tropisms

how are chimpanzees and sunflowers similar?
(im asking this cause i cant figure it out and im super confused and this is for my science class)
Answer:
They are similar because they are both related to each other.
Explanation:
this is a simple diagram of a food chain:
producers --> herbivores --> carnivores --> top carnivores
if all the carnivores die out, why does the number of producers decrease?
i'm not sure but what im thinking is, well if carnivores die, then not many herbivores will die, therefore there isn't that natural soil fertilizer due to the dead bodies.
Explanation:
By all the carnivores, I assume it means regular and top carnivores. This will let the herbivores live longer which means they eat more food, food being producers causing producer numbers to fall drastically

What do you mean by carpool?Carpooling is the practice of sharing car rides so that more than one person can travel in the same vehicle and avoids any need for others to drive themselves to a destination. Carpooling decreases each person's travel costs, such as gasoline, tolls, and the stress of driving, by having multiple people use one vehicle.
Bioswales- Collecting water into natural buffer areas of vegetation or grass
Bioretention - Natural channels designed to collect runoff and remove debris and pollution.
Compost - Organic material that can be added to soil to help plants grow.

Industrial pollution is a negative consequence of the application of scientific knowledge. Thus, the correct option is A.
Why industrial pollution has been increased?Increasing air and water pollution, as well as increased consumption of fossil fuels, occurred from the use of chemicals and fuel in manufacturing resulted in pollution. Acid rain has been increased which is a phenomena that occurs when pollutants are discharged into the sky and subsequently fall back to earth as precipitation as a result of coal combustion.
Science and technology advancements have resulted in significant pollution and degradation of the human environment. Pollution from industries, factories, and locomotives pollutes the air, causing acid rain, global warming, and ozone layer depletion.

Giant Impact Theory: The Moon was formed by a collision between Earth and a planet the size of Mars.
Colliding planetesimal Hypothesis: Planetesimals collided and merged to form the Moon.
Capture Hypothesis: As it passed past, Earth's gravity locked the Moon into orbit.
Accretion Hypothesis: The Moon was produced from the same material cloud that created the Earth.
According to scientists, the following are the recognized theories of lunar formation:
What is giant impact theory?According to this idea, a Mars-sized object named Theia collided with Earth, leaving a large portion of the planet to float in space, eventually forming the Moon. This is the most widely accepted idea of all since the Moon is moving away from Earth and its rocks are fairly similar to those of Earth.
1: According to this idea, the Moon was born somewhere else and was drawn into Earth's orbit by its gravity as it passed by.
2. Capture Hypothesis: According to this idea, the Moon and Earth arose from the same cloud of material at the same time.
3. Accretion Hypothesis: According to this idea, a vast number of small rocky objects known as planetesimals crashed and merged over a long period of time.
4. Colliding planetesimal Hypothesis: According to this idea, the Moon was formed by a huge number of small rocky objects known as planetesimals colliding and combining over a long period of time.

Genetic recombination, production of more offspring than can survive, and struggling with the challenges of the environment are all concepts associated with.
The concepts of genetic recombination, the production of more offspring, and surviving the challenges of the environment are associated with natural selection.
Natural selection and evolutionNatural selection describes the adaptation and modification of populations of living things.
Members of a population are inherently varied, which means they differ in certain respects. Because of these differences, some individuals can be better suited for their surroundings, which is very important in enhancing the chances of surviving and increasing the chances of reproducing as well, thus passing on their adaptive features to their progeny. These beneficial features grow increasingly prevalent in the population over time.
The differences in traits can be explained by changes in the structure of the molecules that make up genes (DNA) are known as mutations. Mutations can occur at random (for example, when replicating cells make a mistake while duplicating DNA) or as a result of exposure to toxic substances or radiation in the environment.
Mutations can be damaging, neutral, or even beneficial, leading to the development of a new, beneficial characteristic. Mutations can be handed on to children when they arise in germ cells.
These processes are all important for the evolution of species.
