Answer:
Both mosses and ferns undergo alterations of generations. ... The gametophyte is prominent is mosses, but the sporophyte is prominent in ferns. The sporophyte of ferns is differentiated into true leaves, stem, and roots. In contrast, mosses lack true leaves, stem or roots.
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.

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.
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.

Treatment Preparation
Your treatment choices are saline solutions with different amounts of salt (NaCl) that can be added to
Clark's blood and affect osmosis in the brain.
In medicine and veterinary medicine, saline solutions are compared with the normal concentration of
sodium (~143 mmol/L) in healthy blood. Three saline solutions are available: isotonic, hypotonic, and
hypertonic.
Concentration of Sodium
Interpret each as higher, lower, or equal to
normal blood Nat concentration.
Lower
Equal Higher
Isotonic Saline
Hypotonic Saline
000
Hypertonic Saline
Answer: isotonic saline is equal
Hypotonic saline is lower
Hypertonic saline is higher
Explanation:
Here, three saline solutions are available: the isotonic saline solution has an equal sodium concentration, the hypotonic solution has a lesser sodium concentration, and the hypertonic solution has a high sodium concentration.
What is the significance of the saline solution in the medications?It is critical in the medication because the solution is made up of a mixture of salt and water through which the drugs are delivered and because it is given in intravenous (IV) therapy or to rehydrate patients when there is a need for it. The saline concentration should be regulated here in this solution, or else it may change the blood cells' structure.
Hence, here, three saline solutions are available: the isotonic saline solution has an equal sodium concentration, the hypotonic solution has a lesser sodium concentration, and the hypertonic solution has a high sodium concentration.

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.

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.

The modified fish contain a growth hormone
gene from a different fish species. As a result, the
modified fish grow rapidly and are ready to sell in

modified fish are able to produce the new growth
hormone because
(1) each of their cells contains the new gene to
produce growth hormone
(2) each gene contains the code to synthesize
carbohydrates
(3) the altered gene directs the mitochondria to
synthesize the hormone

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.

Answer:
Amoebalike protists, flagellates, ciliates, and spore-forming protists.
Explanation:
Protists are eukaryotes, which means their cells have a nucleus and other membrane-bound organelles. Most, but not all, protists are single-celled. Other than these features, they have very little in common. You can think about protists as all eukaryotic organisms that are neither animals, nor plants, nor fungi.
