temperature decreases at high altitude
Answer:
Higher the altitude, the thinner the atmosphere gets. The total heat content of a system is directly related to the amount of matter present, so it is cooler at higher elevations.
Here cooler means decrease in temperature.

5. Count the number of hydrogen ions, oxygens,
and electrons on both sides of the equation
shown. Are they the same?
Answer:
1 hydrogen ion, 2 oxygen atoms and 4elctrons
The number of hydrogen, ions, Oxygen and electrons on both sides of the equations are:
Hydrogen = 4
Oxygen = 2
Electrons on both sides are the same.
What are atoms?Atoms are the smallest unit of matter. Particles inside atoms are referred to as subatomic particles. These can be found throughout the atom in various places. The particles are charged.
A neutron is neutral, a proton is positively charged, and an electron is a negatively charged particle that revolves around the nucleus. The nucleus contains protons and neutrons.
The reaction is when hydrogen attaches with oxygen, it forms water. The formula of water is [tex]\rm H_2O[/tex].
Therefore, Hydrogen = 4, Oxygen = 2 and there are the same numbers of electrons on both sides of the equation.

Which of the following does not occur in an aquatic ecosystem as a result of nutrient loading?
a. acidification of the water
b. algae growth as a result of eutrophication
c. degraded quality of water for human and livestock consumption
d. improved water habitats for human recreation
Answer:
D
Explanation:
Overdosing on nutrients, especially nitrogen and phosphorus, can act as fertilizer and promote an excessive quantity of algae development in water bodies. Thus, option C is correct.
What is nutrient loading?Eutrophication, a process wherein water bodies get an excessive amount of inorganic nutrients, mainly N and P, promotes an excessive growth of plants and algae, is caused by nutrient enrichment in aquatic water bodies.
The calculation of annual loads involves multiplying daily flow by daily nutrient concentration and averaging throughout the course of the year.
Since samples were only taken once a week at most, daily concentration measurements are not available; therefore, daily concentration data must be entered to calculate loads.
Therefore, improved water habitats for human recreation.

please help giving braineist and 25 points.Write two or more sentences to explain how climate change can affect plants and animals.
Rising temperatures lower many species survival rates due to changes that lead to less food, less successful reproduction, and interfering with the environment for native wildlife.
Rising temperatures lead to more frequent droughts, wildfires, and invasive pest outbreaks, leading to the loss of plant species. That has numerous detrimental effects including: Lowered Productivity: Longer droughts and increased number of heat waves will stress plants, causing them to be less productive

(A) trees that are surrounded by wetlands
(B) trees that form an ecological island
(C) trees that have deep roots
(D) trees that grow in a floodplain
Answer: (C) trees that have deep roots
The characteristic feature of an upland hardwood forest is : ( C ) Trees that have deep roots
An characteristic that makes a forest an upland hardwood forest is the presence of a tree canopy which covers more than 50% of the entire forest area emanating from various tree species present in the forest.
Hardwoods have deep roots which help them to get the necessary nutrients from the soil and this type of root system generally supports the structure of the trees overtime.
Hence we can conclude that The characteristic feature of an upland hardwood forest is Trees that have deep roots

the equation for phtotsynthesis
The process of photosynthesis is commonly written as: 6CO2 + 6H2O → C6H12O6 + 6O2. This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products.

1-When you get sick, should you take an antibiotic that a friend or family member offers you (this includes your mom!)? Why or why not?
2- Let's say you're sick and your doctor prescribes you an antibiotic that you have to take for 7 days. If you feel better after 4 days, should you continue taking the antibiotic for the full dose, or stop taking it? Why or why not?
3-If you have a virus, will taking antibiotics cure your infection? Why or why not?
Answer:
1. No! You should only take antibiotics that your doctor prescribes. If you take the wrong antibiotics, or the antibiotics are not necessary, they will not make you feel better and they could contribute to antibiotic resistance by exposing populations of bacteria to antibiotics. This can lead to bacteria evolving resistance genes because of natural selection.
2. No. You must finish the course of antibiotics. By completing the treatment, you increase the odds of killing all the bacteria causing your illness. This means that there are no bacteria left that might develop resistance to the antibiotics
3, No, antibiotics only work against bacteria, and will not work against viral infections. They usually attack the bacterial cell wall, interfere with bacteria reproduction, or interfere with protein synthesis

and dinosaur also lay eggs. But technically egg came first because The oldest fossils of dinosaur eggs and embryos are about 190 million years old. Archaeopteryx fossils, which are the oldest generally accepted as birds, are around 150 million years old, which means that birds in general came after eggs in general.
choose a plant or animal that you think is interesting. describe some of the threats or challenges
Answer:
If I were to choose an interesting plant or animal, I'd choose a "sloth."
Explanation:
A sloth is a mammal that can be found in tropical forests, particularly in the area of Central America and South America. It is a slow-moving animal (4 m/min. to be exact) that makes it prone to several dangers.
Its slow movement may allow predators to take advantage of it because it can never run or save its own life. It is truly helpless in the face of predators.It spends most of its time hanging in trees; thus, it needs trees for survival. If a wildfire would burn the forest down, then the sloths will be homeless. Being on the ground makes them useless, since their body is made for climbing.It is also prone to being electrocuted, since it often mistook electrical lines as branches of trees.Which of the following statements is NOT true?
Photosynthesis converts light energy into chemical energy.
Only a few energy conversions are 100 percent efficient.
Batteries change electricity into chemical energy.
Friction between moving parts can add energy to a system.

What is anabolism? Give an example. What is catabolism also give an example
Answer:
Anabolism is the synthesis of complex molecules in living organisms from simpler ones together with the storage of energy.
Examples of anabolism: bone growth and mineralization, and muscle mass build-up.
Catabolism: the breakdown of complex molecules in living organisms to form simpler ones, together with the release of energy.
Examples of Catabolism: glycolysis, the citric acid cycle, the breakdown of muscle protein in order to use amino acids as substrates for gluconeogenesis, the breakdown of fat in adipose tissue to fatty acids, and oxidative deamination of neurotransmitters by monoamine oxidase.

The neuronal serotonin reuptake transporter 5HTT1 is of great interest to the pharmaceutical sector. Your lab has recently isolated two compounds that bind directly to and act as inhibitors of serotonin uptake; these inhibitors have been named L2001 and L2002. Both L2001 and L2002 seem to reduce serotonin uptake 10-fold when added to cells individually. To characterize how L2001 works, your friend has discovered that L2001 does not affect the ability of 5HTT1 to bind serotonin, but instead seems to decrease the rate at which 5HTT1 is able to change its conformation. Another graduate student in the lab has been working on how L2002 affects 5HTT1 and has determined that L2002 acts in a manner consistent with its being a competitive inhibitor of 5HTT1 (i.e. competes with serotonin for its binding site). Given this information, would you predict that adding L2001 and L2002 together to cells would have a greater effect, a smaller effect, or no effect on 5HTT1 transport compared with the addition of only one of these inhibitors onto cells? Explain

Adding L2001 and L2002 together to cells would have a greater effect on 5HTT1 transport compared with the addition of only one of these inhibitors onto cells
