Explanation:
A farmer has applied a pesticide to control a pest population that is affecting her crops. The pest population has reacted as shown below.
A chart begins with 4 green bugs and 1 brown bug. The brown bug survives and produces brown offspring.
Which best describes the process that the pest population has experienced due to this environmental change?
genetic diversity
natural selection
natural resistance
gene flow
The correct answer is option B. natural selection.
What is Natural Selection?Natural selection is a natural process in which well-adapted organisms tend to survive and reproduce more than less-adapted organisms. For example, tree frogs can be eaten by snakes and birds. This change means that some individuals have more environmentally-adapted traits than others, and their offspring are scarce. There is no doubt that natural selection has shaped the evolution of humankind in our farther past.
Natural selection is an inevitable result of three principles. Most traits are inherited, producing more offspring than can survive, and offspring with more favorable traits survive and have more offspring than individuals with less favorable traits.

What are greenhouse gasses? How does carbon dioxide enter the atmosphere? (Site 1)
Answer:
1. Greenhouse gases are compounds that are able to trap heat in the atmosphere, keeping the Earth's surface warmer than it would be if they were not present. These gases are mainly carbon dioxide; metahne, nitrous oxide, and flourinated gases.
2. Carbon dioxide enters the atmosphere from animals and plants through the process of respiration and the burning of fossil fuels from industries.
Answer:
The greenhouse effect is a natural phenomenon, which, helps maintain the relatively stable, livable, range of temperatures that we find on earth. To better understand how this phenomenon works, scientists have used the analogy of the greenhouse. In a greenhouse, the glass (the atmosphere) allows the radiant energy (light) of the sun to enter. As the radiant energy strikes various plants, gases, and objects in the greenhouse, they heat up. Their heat is then released back into the air of the greenhouse as infrared radiation (heat). This infrared radiation cannot travel through the glass and remains inside the greenhouse, increasing the temperature inside the greenhouse. Temperatures can be controlled, or kept in balance, by allowing some of the heat to remain inside and some to be vented to the outside. Under normal conditions, the earth's atmosphere works in a similar manner. Solar radiation enters the atmosphere and heats up the air molecules, the surface of the earth, buildings, plants, and other objects. These objects in turn, radiate infrared radiation back out into the atmosphere, where some of this radiation is absorbed by the greenhouse gases, and some is radiated out into space. As some of the heat stays in the atmosphere and some escapes into spaces, a balance is maintained allowing our planet to have a relatively stable range of temperatures. Scientists believe that as the greenhouse gases become more abundant in the atmosphere, due mainly to the burning of fossil fuels, they retain more and more infrared radiation, allowing less and less to escape into space, tipping the balance toward heating up the atmosphere, resulting in a changing and warmer climate, planet-wide. This is the accelerated greenhouse effect.

breathing mechanism of fish
Answer:
Breathing Mechanism of Fish. Fish have gills which help them breathe oxygen directly from water without any need to surface. The fish takes water through its mouth, pushing it over the gills and back out through the gill slits. The oxygen enters the blood vessels after being filtered by the gills.
Explanation:
Fish have Gills
Answer:
Fish breathe with the aid of gills.
Explanation:
They take the water rich in oxygen through their mouth and pump it over their gills.

3.) Are there any organisms in this group that eat more than on kind of food? How would you change the order of your cards to reflect this information?
If it's a good answer I'll mark brainliest
Answer:
1. The energy flow to the blue whale would be from the algae and the krill
2. If the killer whale where to be removed from the ecosystem the rest of the ecosystem would increase and wouldn't have a predator to dial down the populations so it would spiral out of control
3. if the algae population increased then the the rest of the ecosystem would increase
4. the fish population would grow and the organisms that the fish feed off of would decrease leaving the rest of the ecosystem to decrease because they would need the krill and algae
Why is it more ethical to test for the waste products of respiration rather than the reactants
Answer:
The knowledge of simple biological reactions tells us that the product of reactions results from the complete or partial use of the reactants. In some reversible reactions, products can be converted to reactants in equal volume. Hence, in reactions that cannot be reversed, as evident in respiration, its waste products can be used to indicate that indeed respiration did take place. When glucose is consumed it is broken down through a series of reactions to give carbon dioxide and water as waste products.

Why does the presence of predators help keep an ecosystem stable?
A. The predators eat the keystone species.
B. The predators keep prey populations balanced.
C. The predators decrease biodiversity
D. The predators stop species from competing,
Answer: B
Explanation:
The predators keep prey populations balanced. Therefore, option (B) is correct.
What are predators?The presence of predators in an ecosystem helps to keep the population of prey species balanced. If the predators were absent, the prey populations could grow unchecked, leading to overconsumption of resources and potentially damaging effects on the ecosystem.
By keeping the prey populations in check, the predators help to prevent such imbalances, contributing to the overall stability and health of the ecosystem.
Predators also tend to prey on the weaker and less fit members of a population, which in turn helps to strengthen the gene pool of the prey species over time. This balance of predator and prey populations is an essential component of a healthy and stable ecosystem.

What are the three main properties of the atmosphere and how do they interact?
Answer:
The three properties of the atmosphere are temperature, air pressure, and humidity. Air pressure decreases with height because the mass of air above you decreases. The temperature varies, but it continues to increase near the end in the exosphere. Humidity is not directly affected by altitude
Hope it helps :)
Explanation:
What Is Air?
You probably don't think too much about air, but it's all around you. It takes up space and is pushing on you right now. There isn't air in space, and if you were to suddenly find yourself in the middle of space without a spacesuit, you'd be aware of how important air is to your survival. Obviously, you need the oxygen to breathe, but if there isn't any air to push on you, bad things start to happen. For starters, bubbles would form in your bodily fluids, and you would double in size. Yikes. Let's get a spacesuit on you ASAP!
So… what is air? Air is a mixture of gases, water vapor, and other substances, and it has specific properties, or characteristics.
Air is made up of gases
Air has mass
Air exerts pressure and has weight
Air can be compressed
Air is impacted by temperature
Wow, that's a lot of new terminology! Let's check out each point on that list.
Mass and Mixture of Gases
Mass is defined as how much stuff an object contains - and by stuff, I mean matter, like atoms and molecules. And even though you can't see it, air has a lot of atoms and molecules. Air is a gas (as opposed to a liquid or a solid) and contains about 78% nitrogen, 21% oxygen, and 1% argon. There are other trace gases in air, like helium, carbon dioxide, and neon, just to name a few.
Air also contains water vapor; the amount varies depending upon the location (think tropical, humid Hawaii versus the dry desert of Las Vegas). Finally, air contains other things, like dust, pollen, and bacteria.
What proof is there that air has mass? Well, if you blow up a balloon with air, the balloon expands. It's expanding due to the gases, water vapor and other materials that give air mass.
Pressure and Weight
Let's move on to pressure, or when something exerts a force on something else. All of those atoms and molecules we just mentioned are moving all around you. The pressure you're experiencing right now is due to all of those atoms and molecules bumping into you, as well as the weight of all of the air molecules and atoms above you.
And how do we know those atoms and molecules have weight? If you were to weigh an empty balloon and then fill it with air and reweigh it, you'd notice it gained weight. This is because, as long as there's gravity, everything with mass has weight (including air).
And here's a fun fact: at sea level all of the air above you exerts 14.7 pounds per square inch on your body (as well as everything around you). If you're below sea level, the number is greater (because you have more air pushing

On the basis of these data, which group of robins most likely shares a most recent common ancestor
with the Norfolk Island robins?
Hello. You forgot to enter the necessary data for this question to be answered. The data are shown in the figure attached below:
Answer:
Red-capped Robin is the group of Robins that share a more recent common ancestor with the Norfolk Island robins.
Explanation:
Red-capped Robin is the group of Robins that share a more recent common ancestor with the Norfolk Island robins, this can be seen by the degree of genetic similarity between these two species, since the Red-capped Robin has 98.2% of genetic similarity .
When two species have the same common ancestor, these species have great genetic similarity and the more recent this ancestry is, the greater the genetic similarity between the species.

You have sampled a population in which you know that the percentage of the homozygous recessive genotype (aa) is 25%. Calculate the frequency of the "A" allele. *
1 point
0.5
0.4
0.25
0.6
Answer:
.5
Explanation:
Remember that p = dominant allele, q = recessive allele. Use the Hardy-Weinberg equations:
p^2 + 2pq + q^2 = 1 (AA + Aa + aa = 1)
So aa = q^2. Take the square root, and we'll have just q by itself.
√a^2 = √.25 = .5
So the frequency of the a allele (recessive) = .5.
p + q = 1
p + .5 = 1
p = .5
The frequency of the A allele is .5.
