“Chad is attempting to determine how different colors of light
affect plant growth. Chad places one spider plant in a cabinet
under a blue light and one spider plant in a cabinet under a red
light. Chad knows he needs to compare his plants to a plant
grown under white light so he places a third spider plant on the
window sill where the sun shines. All plants are the same age
and are given equal amounts of light time, plant food and water.
At the end of a two week period, Chad will measure the height of
each plant.”

B Mutations increase the genetic variation within a population, and some of the variants may provide an advantage to individuals over time
C Mutations help stabilize the genetic variation within a population, and only one or two variants generally provide an advantage to individuals.
D Mutations help reduce the genetic variation within a population, and thus increasing the rate that new adaptations develop.
Answer:
B. Mutations increase the genetic variation within a population, and some of the variants may provide an advantage to individuals over time
The role of mutations in evolution by natural selection is option b. Mutations increase the genetic variation within a population.
Role of mutation in evolution:The mutation is significant as the first step of evolution since it developed the new DNA sequence for the specific gene that developed the new allele.
Also, at the same time, it rise the genetic variation within the population also it provides as an advantage to individual

1.) Which of the word below are organelles? (check all that apply.)
- chloroplast
- leaf
- enzyme
- mitochondrion
- vacuole
- DNA
2.) Which of the choices below is a small organelle, made of RNA and protein; as well as a site of protein synthesis?
- vacuoles
- ribosomes
- Golgi bodies
- chloroplasts
Answer:1) Chloroplast, mitochondrion and vacuole are the organelles
Explanation: a leaf is a organ of a plant and is not found in cells. An enzyme creates chemical reactions in the body. the DNA is just the plan on how to build the cell and how to do certain cellular processes. therefore a chloroplast, mitochondria and vacuole are all organells. also the mitochondrion creates energy, a vacuole stores food and water and a chloroplast converts the suns energy into food

If a cell's RIBOSOMES were to stop working, what would immediately happen to the
cell?
A. Energy would not be produced
B. The cell would not be able to stop things from getting in and out
C. Materials would not be transported
D. Proteins would not get made
Answer:
D. Proteins would not get made
Explanation:
According to google: If the ribosomes were not working properly then your cell would not be producing proteins. If your cell did not produce proteins enzymes would not be available to speed up reactions throughout your body, and they would also not be available to make the many organelles made with proteins such as microtubules which would cause many other problems within the cell.
Answer:
D. Proteins would not be made.
Explanation:
Humans have found that we can eat the space cow, and it's delicious! There are no laws currently in place protecting the environment of Planet Z. What would happen to the populations of both the Space Cows and the Vaderians if humans began to hunt for Space Cows on Planet Z?
Will it increase or decrease and why?
if humans begin hunt the space cows they will eventually become extinct causing the vaderians to lose a main source of food which would most likely cause their population to also decrease.

After cooking the hot dogs, your friend's mom reminds you not to leave the grill out, or the iron (Fe) in the grill will react with oxygen (O2) in the air to produce rust (Fe2O3). a. Write a balanced equation for this reaction. Be sure to show your work.
Answer:
Explanation:
Oxygen gas and water must be present for iron to rust.
A region of the metal’s surface serves as the anode, where oxidation
occurs:
Fe(s) → Fe²⁺ (aq) + 2 e⁻
The electrons given up by iron reduce atmospheric oxygen to water at the cathode, which is another region of the same metal’s surface:
O₂ (g) + 4H⁺ (aq) + 4 e⁻ → 2 H₂O (l)
The overall redox reaction is:
2 Fe(s) + O₂(g) → 4H⁺(aq) + 2Fe²⁺ (aq) + 2 H₂O(l)
The Fe²⁺ ions formed at the anode are further oxidized by oxygen:
4 Fe²⁺ (aq) + O₂(g) 1 (4 + 2x) H₂O (l) → 2 Fe₂O₃ . xH₂O(s) + 8 H⁺(aq)
This hydrated form of iron(III) oxide is known as rust. The amount of water associated with the iron oxide varies, so we represent the formula as 2 Fe₂O₃ . xH₂O.
A poisonous substance enters the food chain through the soul. This substance doesn't break down in the bodies of living organisms. Suggest the trophic level that will have the highest level of poison substance.Explain your answer. (2)
Explanation:
Biomagnification, also known as bioamplification or biological magnification, is any concentration of a toxin, such as pesticides, in the tissues of tolerant organisms at successively higher levels in a food chain.[1] This increase can occur as a result of:
Persistence – where the substance cannot be broken down by environmental processes
Food chain energetics – where the substance's concentration increases progressively as it moves up a food chain
Low or non-existent rate of internal degradation or excretion of the substance – mainly due to water-insolubility
In biomagnification the concentration of the persistent toxins (crosses) increases higher up the food chain.
In this scenario, a pond has been intoxicated. As we go further into the food chain, the toxin concentration increases, causing the top consumer to eventually die of intoxication.
Biomagnification is the build up of toxins in a food chain. The DDT concentration is in parts per million. As the trophic level increases in a food chain, the amount of toxic build up increases. The x's represent the amount of toxic build up accumulating as the trophic level increases. Toxins build up in organism's fat and tissue. Predators accumulate higher toxins than prey.
Biological magnification often refers to the process whereby certain substances such as pesticides or heavy metals work their way into lakes, rivers and the ocean, and then move up the food chain in progressively greater concentrations as they are incorporated into the diet of aquatic organisms such as zooplankton, which in turn are eaten perhaps by fish, which then may be eaten by bigger fish, large birds, animals, or humans. The substances become increasingly concentrated in tissues or internal organs as they move up the chain. Bioaccumulants are substances that increase in concentration in living organisms as they take in contaminated air, water, or food because the substances are very slowly metabolized or excreted.
Contents
Processes Edit
Although sometimes used interchangeably with "bioaccumulation", an important distinction is drawn between the two, and with bioconcentration.
Bioaccumulation occurs within a trophic level, and is the increase in the concentration of a substance in certain tissues of organisms' bodies due to absorption from food and the environment.
Bioconcentration is defined as occurring when uptake from the water is greater than excretion.[2]
Thus, bioconcentration and bioaccumulation occur within an organism, and biomagnification occurs across trophic (food chain) levels.
Biodilution is also a process that occurs to all trophic levels in an aquatic environment; it is the opposite of biomagnification, thus when a pollutant gets smaller in concentration as it progresses up a food web.
Lipid, (lipophilic) or fat soluble substances cannot be diluted, broken down, or excreted in urine, a water-based medium, and so accumulate in fatty tissues of an organism, if the organism lacks enzymes to degrade them. When eaten by another organism, fats are absorbed in the gut, carrying the substance, which then accumulates in the fats of the predator. Since at each level of the food chain there is a lot of energy loss, a predator must consume many prey, including all of their lipophilic substances.
For example, though mercury is only present in small amounts in seawater, it is absorbed by algae (generally as methylmercury). Methyl-mercury is the most harmful variation of mercury. It is efficiently absorbed, but only very slowly excreted by organisms.[3] Bioaccumulation and bioconcentration result in buildup in the adipose tissue of successive trophic levels: zooplankton, small nekton, larger fish, etc. Anything which eats these fish also consumes the higher level of mercury the fish have accumulated. This process explains why predatory fish such as swordfish and sharks or birds like osprey and eagles have higher concentrations of mercury in their tissue than could be accounted for by direct exposure alone. For example, herring contains mercury at approximately 0.01 parts per million (ppm) and shark contains mercury at greater than 1 ppm.[4]
DDT is thought to biomagnify and biomagnification is one of the most significant reasons it was deemed harmful to the environment by the EPA and other organizations. DDT is stored in the fat of animals and takes many years to break down, and as the fat is consumed by predators, the amounts of DDT biomagnify. DDT is now a banned substance in many parts of the world.[5]
Which of the following describes a benefit of
biodiversity to an ecosystem?
A. decreases the energy flow through the ecosystem
B. increases the maximum number of trophic levels
C. increases the maximum biomass of the ecosystem
D. allows the ecosystem to withstand environmental changes
Answer:
D. allows the ecosystem to withstand environmental changes
Explanation:
One very significant importance of biodiversity is that it allows the ecosystem to withstand changes in the environment.
Biodiversity is the variation of life forms on the earth.
Due to instability in the ecosystem as a result of natural and human induced factors, a highly biodiverse system is able to tolerate these inconsistencies. A not so biodiverse system would crumble under environmental changes they cannot withstand.Scientific law provides descriptions. O True O False

impact of climate change on ecosystems in Karnataka
right answer will be awarded
Answer:
Explanation:
Flanked by the Arabian Sea, Karnataka is a coastal state in
the south west of India. It is the eighth largest state by size
and the ninth by population.While the Western Ghats
account for a bulk of the state’s forest cover, over 77 per cent
of its geographical area is arid or semi-arid. Much of this is
concentrated in North Karnataka. Karnataka is also the third
most urbanised state in the country and water availability is a
major concern. In terms of its economy, over 50 per cent of the
state’s Gross State Domestic Product comes from the services
sector. There has, however, been a dip in manufacturing and a
reduction in mining and quarrying operations.
Much of Karnataka’s environmental legacy revolves around two
issues; industrial activity in the Ghats in the form of paper mills,
gold and iron mining, and hydro power generation; and the
supply and usage of water.10 The most notable manifestation of
the latter is the Cauvery water dispute between Karnataka and
Tamil Nadu.11 A related concern is the sharp disappearance of
lakes and water bodies, owing to encroachment, pollution and
infrastructural activity in the state. Karnataka has a number of prominent scientific and researchbased institutions based in its capital city Bengaluru (formerly
Bangalore) and this has played an important part in the framing
and content of Karnataka’s SAPCC.
