An investigation was carried out over a five-year period to measure the effect of color on the survival of trout in a stream. The stream contained many brightly colored stones and food was plentiful. At the start of the investigation (year 0), 100 bright-colored trout and 100 drab-colored trout were placed into a section of the stream that had been blocked with netting. Investigators monitored the trout populations for five years and recorded the water condition each time a count was done. The data collected are shown in the table below.
Year Bright colored trought Drab colored trought condition of water
0 100 100 clear
1 64 36 clear
2 86 25 clear
3 25 77 cloudy
4 14 86 cloudy
5 90 9 clear
How does this demonstrate that natural selection depends on the environment? This will be graded based on your overall claim and supporting statements, use of direct evidence from the data table, and your reasoning (CER).
Explanation:
In the given question, the data has been collected for the population of two variations of colour in trout against their environment.
Natural selection refers to a mechanism of evolution by which species evolve as a consequence of their environment.
From the data, we can predict that the brightly coloured trout have better chances of survival in the clear water as the number of individuals of bright-coloured trout is found to be high in clear water.
The number of darkly coloured trout is found to be high in cloudy water in the data which shows that the chances of survival of these trout are better in the cloudy water.
The trait which increases the reproductive fitness of the organism will pass on to their generations that is will be inherited.
This shows how the population of trouts have adapted to survive in a different environment or how nature selects the different variations of the population of trout.

3.Whenever the surfaces in contact tend to move or move with respect to each other, the force of friction comes into playRequired to answer. Single choice.
Answer:
The correct answer is - Friction occurs irrespective of the state of the matter.
Explanation:
Friction is the force that takes place when there are two different surfaces slide or moves across one another and causes a resistance between surfaces. The friction always takes place opposite direction to the other surface direction of moving.
Pushing a book on a table, pulling a heavy cart on road all are examples of friction. The friction that occurs in liquids and gases is called fluid friction. Thus, the friction takes place irrespective of the state of the matter.

I believe the answer is parasitism. The cuckoo bird uses sneaky tactics to trick the warbler into doing the parenting for them
Answer:
I believe the answer is parasitism
Explanation:
it makes the most sense within this scenario. The cuckoo bird invades another oragnism's way of life, harms the other eggs in the process, and lives off of the shelter and nurtrients that would have been the baby warblers given by the warbler mom.
mutualism: symbiosis that is beneficial to both organisms involved
commensalism:an association between two organisms in which one benefits and the other derives neither benefit nor harm.
parasitism:the practice of living as a parasite in or on another organism.

Explanation:
Explain the water cycle in one paragraph.
Answer:
The water Cycle
Explanation:
The water cycle or hydrologic is a continuous cycle where water evaporates, travels into the air and becomes part of a cloud, falls down to earth as precipitation, and then evaporates again. This repeats again and again in a never-ending cycle. Water keeps moving and changing from a solid to a liquid to a gas, over and over again.
Precipitation creates runoff that travels over the ground surface and helps to fill lakes and rivers. It also percolates or moves downward through openings in the soil to replenish aquifers under the ground. Some places receive more precipitation than others do. These areas are usually close to oceans or large bodies of water that allow more water to evaporate and form clouds. Other areas receive less precipitation. Often these areas are far from water or near mountains. As clouds move up and over mountains, the water vapor condenses to form precipitation and freezes. Snow falls on the peaks.

Group of answer choices
a.The light wave will bend as it moves from the air to the water because it changes speed and gets refracted.
b. The light wave will bend as it moves from the air to the water because it changes speed and gets reflected.
c. The light wave will split into different colors as it moves from the air to the water because it gets refracted.
d. The light wave will bounce back into the air when it moves into the water because it gets refracted from the bug to the fish’s eye.
Question:
In order for a fish to see a bug just above the surface of the water, light travels from the insect through the air and crosses into the water until it reaches the fishes' eye. Which statement is true regarding the light wave as it travels through the different media?
Answer:
D. The light wave will bounce back into the air when it moves into the water because it gets refracted from the bug to the fish's eye.
Just A Few Notes From The Internet:
The light waves will travel straight from the bug to the fishes' eye because that is the most direct path. The light waves will travel straight from the bug to the fishes' eye because there is no change in medium. The light waves will bounce off the surface of the water and the fish will see it.

Why is algae able to endure photosynthesis when grown under green light? (has something to do with absorbing the color green)
Chlorophyll makes plants and algae appear green because it reflects the green wavelengths found in sunlight, while absorbing all other colors.
However, chlorophyll is not actually a single molecule. There are 6 different chlorophylls that have been identified. The different forms (A, B, C, D, E and F), each reflect slightly different ranges of green wavelengths. Chlorophyll A is the primary molecule responsible for photosynthesis. That means that chlorophyll A is found in every single photosynthesizing organism, from land plants to algae and cyanobacteria. The additional chlorophyll forms are accessory pigments, and are associated with different groups of plants and algae and play a role in their taxonomic confusion. These other chlorophylls still absorb sunlight, and thus assist in photosynthesis. As accessory pigments, they transfer any energy that they absorb to the primary chlorophyll A instead of directly participating in the process. Chlorophyll B is mainly found in land plants, aquatic plants and green algae. In most of these organisms, the ratio of chlorophyll A to chlorophyll B is 3:1. Due to the presence of this molecule, some organizations will group the green algae into the Plant Kingdom. Chlorophyll C is found in red algae, brown algae, and dinoflagellates. This has lead to their classification under the Kingdom Chromista. Chlorophyll D is a minor pigment found in some red algae, while the rare Chlorophyll E has been found in yellow-green algae. Chlorophyll F was recently discovered in some cyanobacteria near Australia. Each of these accessory pigments will strongly absorb different wavelengths, so their presence makes photosynthesis more efficient.
3. Photosynthesis observes the law of conservation of mass and energy because
a. it contains both matter and energy

What genotype would a long-haired guinea pig have?
Answer:
What genotype would a heterozygous short haired
guinea pig have? Ss
What genotype would a pure breeding short haired
guinea pig have? SS
What genotype would a long-haired guinea pig have? ss
Explanation:
I just used S to substitute for my alleles, but you can use any letter. (For example: Ee, EE, ee)
If H is the dominant allele for short hair, we would have the followng genotypes:
Heterozygous short haired: Hh
Pure breeding short haired: HH
Long-haired guinea pig: hh
What is a Dominant Allele?A dominant allele is an allele of a trait that always expresses itself in the presence of a recessive trait in an allelic pair. Capitral letter is usually used to denote the dominant allele.
Let H represent short hair (dominant allele)
h represents long hair (recessive allele)
Therefore, we would have the following:
Genotype for heterozygous short haired would be: Hh
Genotype for pure breeding short haired would be: HH
Genotype for long-haired guinea pig would be: hh

in humans, dimples are dominant to no dimples. cross a woman with no dimples with a man who is heterozygous for dimples. determine the phenotypic and genotypic ratio of their offspring. show a punnett square to support your answer
Genotype: 50% Aa and 50% aa
Phenotype: 50% Dimples and 50% no dimples
Explanation: Using a punnet square, we can figure out that the mother is recessive and the father is heterozygous. Putting the mother at the top of the square and the father on the side, you end up with the results above by crossing each square with the corresponding letters. It's okay if the letters end up backwards. Just be sure to face them the right direction, capitals being first once you finish.

Question 9
How do animals get nitrogen that is stored in the soil?
O A) Animals do not take in the nitrogen stored in the soil.
O B) Bacteria change the nitrogen into a gas that the animals breathe.
OC) Plants ab orb the nitrogen from the soil and animals can eat the plants.
O D) The animals can eat the soil and absorb the nitrogen through their digestive system
Answer: C) Plants absorb the nitrogen from the soil and animals can eat the plants.
Heterotrophs, specifically herbivores and omnivores, are animals that eat plants (autotrophs) to get the nutrients they need. Those that eat the plants get the nitrogen from the plant that has absorbed it from the soil. Omnivores and carnivores eat the herbivores to get nitrogen that way. For more more information, take a look at the nitrogen cycle.

In cats grey color (G) is dominant to white color (g). If a white female has kittens with a heterozygous male, and the mother is showing that she will be having 9 Kittens, how many kittens would you expect to be white? (Round down to the nearest whole number, you cannot have partial kittens)
Answer:
Rounding down to the nearest whole number, 5 Kittens will be white.
Explanation:
Available data:
grey color (G) is dominantwhite color (g) is recessivewhite female, ggheterozygous male, Gg9 KittensCross:
Parental) Gg x gg
Phenotype) Grey White
Gametes) G g g g
Punnet square)
G g
g Gg gg
g Gg gg
F1) Genotypes:
1/2 = 50% will be Gg
1/2 = 50% will be gg
Phenotypes:
1/2 = 50% will be Grey (Gg)
1/2 = 50% will be white (gg)
To calculate the number of kittens that will be white, we need to consider the proportions of cats that will be white in the F1 and that the total number of kittens is 9. So
100% of the progeny ------------------------------- 9 kittens
50% of the progeny----------------------------------X = (50 x 9)/100 = 4.5 kittens ≅ 5 Kittens
A cat can not have 4.5 kittens, so we must round down to the nearest whole number. 4.5 ≅ 5 Kittens
