Explanation:
depression
unstable mental health
constant anxiety
overthinking
Answer:
Regular physical activity promotes growth and development and has multiple benefits for physical, mental, and psychosocial health that undoubtedly contribute to learning.
• Specifically, physical activity reduces the risk for heart disease, diabetes mellitus, osteoporosis, high blood pressure, obesity, and metabolic syndrome; improves various other aspects of health and fitness, including aerobic capacity, muscle and bone strength, flexibility, insulin sensitivity, and lipid profiles; and reduces stress, anxiety, and depression.
Sedentary behaviors such as sitting and television viewing contribute to health risks both because of and independently of their impact on physical activity.
• Health-related behaviors and disease risk factors track from childhood to adulthood, indicating that early and ongoing opportunities for physical activity are needed for maximum health benefit.
What do cells contain?
Answer:
cells consists of cytoplasm enclosed within a membrane, which contains many biomolecules such as protiens and nucleic acids.
How might a plant cell compensate for the excessive membrane fluidity that occurs during prolonged exposures to elevated temperature?A) Reduce membrane cholesterol content.B) Alter the lipid composition to have longer fatty acyl tails and fewer double bonds.C) Alter the lipid composition to have shorter fatty acyl tails and more double bonds.D) Alter the lipid composition to have shorter and more unsaturated fatty acyl tails.E) Reduce cholesterol content and alter the lipid composition to have shorter fatty acyl tails.
Answer:
E) Reduce cholesterol content and alter the lipid composition to have shorter fatty acyl tails.
Explanation:
Reducing the amount of fat makes the tissues or membranes have less plasticity, since these fatty acids with high temperatures increase their fluidity, are less dense and give greater plasticity in their elastic modulus.

You and your friends go to the beach for vacation. You all walk down to the beach to go swimming. When you get there, you see the water is murky and green, and there are algae blooms floating on top. If it is excess nutrients which are feeding the algae blooms and lowering the oxygen content in the water, that process is called:_______.a. nutrient cycling.
b. nitrification.
c. eutrophication.
d. hypoxia.
Answer: The process is called EUTROPHICATION. The correct option is C.
Explanation:
Eutrophication is a type of environmental pollution where by there is an increase in nutrient salts of a water body which can lead to structural changes in the affected aquatic ecosystem. These changes includes:
--> Increase in production of algae: this effect causes algae blooms which makes the water murky, greenish and unpleasant for certain activities such as swimming.
--> Decrease in aquatic life: the presence of excessive growth of algae which are often degraded by microorganisms. When the rate of degradation of the algae by microorganisms is greater than that of oxygen regeneration a hypoxic state occurs which is harmful to aquatic life example fishes.

An apple, potato, and onion all taste the same if you eat them with your nose plugged
Answer:
True
Explanation:
Answer:
True
Explanation:
It is frequently quoted that upwards of 80% of our taste is made up by smell. So if you plug your nose and cover your eyes, the taste between an apple and onion should be indistinguishable. Potato's will also taste the same .

what cause asexual reproduction
Answer:
It is a type of reproduction that does not involve the fusion of gametes or change in the number of chromosomes.
The offspring that are produced by asexual reproduction from a single cell or from a multicellular organism inherit the genes of that parent and thus have the sane identical identities of the parent.
5. Some advantages of sexual reproduction include: (select all that apply) *
a.genetic variation
b.improves chances of adapting to the envionment
c.helps species survive catastrophes
d.Certian genes work beter than other
Some advantages of the sexual reproduction include genetic variation. Genetic variation results into changes in the genetic material (DNA). Thus, the correct option is A.
What is Genetic variation?Genetic variation is the difference in the DNA (deoxyribonucleic acid) among individuals or the difference between different populations. The multiple sources of genetic variation include mutations and genetic recombination. Mutation is the changes in the genetic material of an organism which are the ultimate sources of genetic variation, however other mechanisms, such as genetic drift, contribute to it, as well.
Genetic diversity is important because it gives the species a better chance of survival through variations. However, the genetic diversity can be lost from the species when the populations get smaller and isolated from each other, which decreases a species' ability to adapt and survive better in the condition.
Therefore, the correct option is A.

The Ebola virus can often have symptoms similar to bacterial pneumonia, an infection of the lungs. These symptoms include chest pains, shortness of breath, and fever. Which statement best summarizes the differences between these two diseases? (SC.6.L.14.6)a.Viruses can replicate because they are living organisms, while bacteria cannot. b.Viruses are not living organisms, but bacteria are living. c.Viruses can be beneficial to live organisms but bacteria are often infectious. d.Viruses are living organisms, while bacteria are not.
Answer:
Eblow is a terrible thing.
Explanation:
Answer:
I think its, option b) Viruses are not living organisms, but bacteria are living.
Explanation:
The other options don't fit "summarize the differences b/w bacteria and virus", or simply don't make sense...
Bacteria can replicate as well, not only virus, so that cannot be a difference
The virus is often the one being more dangerous, there is something called "good bacteria"
A virus isn't living, (for the sake of this answer), and we all know for sure that bacteria is living
So, that's how option b is correct

How does weathering affect Earth's surface?
Answer:
Weathering can wear away any exposed surface on earth over time. It can cause rough surfaces to become smooth, much like a tumbler smooths a rock. An obvious example of weathering is the change of the landscape at the sea. The tides can cause the beach to become smaller or larger.
Explanation:
Answer:
Weathering is the breaking down or dissolving of rocks and minerals on Earths surface.
Explanation:
Once a rock has been broken down, a process called erosion transports the bits of rock and minerals away. ... Weathering and erosion constantly change the rocky landscape of Earth. Weathering wears away exposed surfaces over time.
What effect does development, through erecting buildings and concrete pavement, have on the recharge of aquifers and the quality of the water?
Answer:
Infiltrate rate decreases and also water quality.
Explanation:
There is adverse effect of erecting buildings and concrete pavement on the recharge of aquifers and the quality of the water because the water is unable to infiltrate inside the soil due to concrete floor and the recharging of aquifers is not possible. These buildings and concrete pavements also reduces the quality of water due to degradation of sediments present in the building with the passage of time.

if a nutrient were in short supply in an ecosystem, how might it effect an organism
Answer:
Its leads to a deficiency
Explanation:
If a nutrient is in short supply in an ecosystem, it will lead to a deficiency of such nutrient in organisms that are in need of the nutrient.
Such a deficiency can lead to diseases in the ecosystem. If organisms that requires the nutrient cannot find an alternative, it will seriously affect their well being. Such deficiency often lead to very dire consequences for the balance of the ecosystem at large.
