Explanation:
Pesticides often do not just kill the target pest but also poison
inects in and
around the fields. These insects with the pesticides can be eaten by other animals and poison them.
Some pesticides are suspected of disrupting the
of wildlife and people. These
chemicals
because they are fat soluble and get passed up the food chain
by
Unlike pesticides, fertilizers are not directly toxic but their presence in
freshwater and marine areas alters the
system, and in consequence the species
composition of specific ecosystems. Their most dramatic effect is
resulting in an
explosive growth of algae due to
nutrients. This depletes the water of dissolved
oxygen, which in turn can kill fish and other aquatic life.
Answer:
Other problems of pesticide use include most pesticides kill beneficial species as well as the target pest species, pesticides do not stay put, pesticides harm wildlife, and pesticides can threaten human health. Farmers pay more and more for a pest control program that often becomes less and less effective.

The diagram below illustrates a natural Earth process through which the atmosphere
traps heat. Many scientists hypothesize that human activities are accelerating this
process, resulting in a global warming trend. What human activity is believed to have an
adverse effect on the natural process pictured here?
Answer: c. burning of fossil fuels.
Explanation:
Carbon Dioxide and other greenhouse gases like it are the reason some of the sun's heat is trapped in the atmosphere instead of leaving back into space. Any process which increase the amount of carbon dioxide in the atmosphere therefore can increase global warming.
One of the major human activities that involves releasing carbon dioxide is the burning of fossil fuels. We use fossil fuels for many things including producing electricity and driving. When this happens we release a lot of carbon dioxide into the atmosphere thereby making global warming worse.

What is the MOST recent evidence supporting plate tectonics?
A) GPS monitoring of plate speeds and movements
B) the WWI discovery of paleomagnetic reversals
C) the 1963 mapping of the tectonic plate boundaries
D)C-14 dating of marine fossils found in the himalayas
A.) GPS monitoring of plate speeds and movements.
I know this is correct because it is constantly paying attention to what is going on with the tectonic plate, monitoring their movement every day, making it the most recent.
Hope this helps and have a nice day.

Classification of organisms
Answer: It is also known as Metazoa.
Monera − It comprises unicellular organisms, e.g. bacteria.
Protista − Similar to monera (unicellular), but more developed and complex. It contains nucleus.
Plantae − All plants from smallest (such as algae) to the largest (such as Pine, Eucalyptus trees, etc.) are studied...
Fungi − It is a group of eukaryotic organisms that comprises...

Complete question:
You will find the complete question in the attached files
Answer:
1)
Alienus quadlegicus: Mouth opened and no armsAlienus hairicus: Mouth opened, hairyAlienus tritoothicus: Mouth opened, not hairyAlienus stripicus: Mouth not opened, hornsAlienus bloblicus: Mouth not opened, No legsAlienus fuzzicus: Mouth not opened, Legs2) Genus Alienus
3) Morphological characteristics of aliens are used to identify them and to name them.
Explanation:
1) The dichotomous keys give you information about the groups that are being differentiated to correctly identify them. All you need to do is follow the description of the organisms and the numbers where each description drives you. If you observed correctly the organism, you will reach the scientific name, or genus, or any other taxonomic group you are looking for.
2) Taxonomy is the study of different organisms, their classification into categories according to their morphological and molecular characteristics and their evolutionary relationships. A binomial name is assigned to each organism, composed of a genus and the epithet.
Among all the categories where organisms are classified, we can find the genus, which includes many species that share some common characteristics that are used to group them together.
In this example, Alienus is the genus of all these aliens species.
3) Morphological characteristics of aliens are used to identify them and to name them.
Alienus quadlegicus: Four-legged alienAlienus hairicus: Hairy alien.Alienus tritoothicus: Alien with three teethAlienus stripicus: Alien with striped hornsAlienus bloblicus: Alien with no shape. Shapeless massAlienus fuzzicus: Short fine-haired alien.

describe in detail Alfred Wegener's idea of continental drift
HELPP
Answer:
Continental drift was a theory that explained how continents shift position on Earth's surface. Set forth in 1912 by Alfred Wegener, a geophysicist and meteorologist, continental drift also explained why look-alike animal and plant fossils, and similar rock formations, are found on different continents.
Explanation:
Can someone do this quick?
Answer: A.
Explanation:
Palisade mesophyll cells contain the most amount of chloroplasts with an average of 30–70 chloroplasts per cell so they will be number 2 in the graph.
Spongy mesophyll cells contain less chloroplasts than their palisade counterparts to enable them have a larger surface area for gas diffusion.
The guard cells have the least amount of chloroplasts on average and so will be number 1. on the graph.

why arent two hydrogen atoms bonded together considered a compound
Answer:
Since at least two elements form a compound, and here we have only one. And we have two hydrogen atoms bonded together in this situation, so we have a bond, so there's just one element, and in order to have a compound, we need to have at least two elements.

Which of the following statements about human society and limiting factors is true?
a. Modifications made to the environment to reduce the impact of limiting factors can cause
disruption to the natural balance of an ecosystem.
b. Humans cannot modify their environment to adapt it to their needs.
c. Humans can completely overcome the factors that limit population size.
d. Limiting factors are of no concern to human society, because they do not affect human
populations
The statement that is true about human society and limiting factors is "Modifications made to the environment to reduce the impact of limiting factors can cause disruption to the natural balance of an ecosystem." The correct option is A.
What are limiting factors?Limiting factors are the factors that limit the growth of populations. For instance, the limiting factors for humans might be a lack of food or water. Limiting factors may be biotic or abiotic. Abiotic factors include nonliving aspects like temperature and rainfall while biotic factors are the living aspects like predators and competition.
Modifications made to the environment to reduce the impact of limiting factors can cause disruption to the natural balance of an ecosystem. These modifications include the introduction of a new species, the clearing of land for agriculture or industry, or pollution.
The new species can lead to the elimination of the native species, the clearing of land can cause habitat loss, and pollution can have numerous effects like air and water pollution.
Therefore, the correct option is A.

What else do you think plants may need to grow and go through their normal processes?
Plants need water, oxygen, soil, and solar energy.
Those are the only things that I believe plants need. They need water for food and Solar Energy (basically Vitamin D which you get from the sun) and soil to grow. Obviously they need oxygen to be able to survive.
