5. what should Homer's conclusion be?
Answer:
1) initial observation: growth of a strange green slime in the shower
2) Control Group: Half of the shower that was sprayed with water
3) Independent variable: volume of coconut juice sprayed
4) Dependent variable: disappearance of the green slime
5) spraying coconut juice is not effective when trying to get rid of slime in the shower after 3 days
Explanation:
The question wants to test your ability to interpret an experiment and identify the various components in an experimental design. Hence, I will explain the major concepts found in en experimental design:
Initial observation: These are the factors that precede the initiation of an experiment, and it is what the experiment seeks to change or support. In this case, the observation of slime in Homer's bathroom initiated the experiment.Control Group: The control group in an experiment is the group that does not receive treatment or intervention by the researcher, and serves as a benchmark for measuring the change occurring in the treatment group. In this example, the half of the bathroom sprayed with water, did not receive any intervention which is spraying with coconut juice. Independent variable: These are the variables that are completely under the control of the researcher and can be varied at will. The volume of coconut juice sprayed is completely under Homer's cntrol.Dependent variable: The dependent variable is the variable that changes or is expected to change as a result of the changing of the indepenedent variable. The outcome is outside the control of the researcher. Here, the disappearance of the slime is the dependent variable, because it depends on the spraying of coconut juiceConclusion: The conclusion is a statement made as a result of the observed results of the experiment. In this case, there was no change on the slime in the bathroom after three days of spraying with coconut juicewhat is convection?

(iii) List TWO structural differences between this polysaccharide and glycogen.
[2 marks]
Answer:
Cellulose, starch, and glycogen are all polymers of glucose, but differ in form and function because of the optical isomer involved, the length of the polymers, and the degree of branching.CELLULOSE is an unbranched, long chain glucose polymer held by ß-1,4 glycosidic bonds. The straight, tightly packed chains give cellulose high tensile strength and resistance to hydrolysis.
STARCH is a mixture of two polysaccharides: amylose (unbranched with alpha-1,4 glycosidic bonds) and amylopectin (branched with alpha-1,6 glycosidic bonds). The alpha-1,4 glycosidic bonds and more branched nature of starch account for ith physical properties; starch is powdery and more easily hydrolyzed than cellulose, which exists as tough microfibrils.
GLYCOGEN, like starch, is a branched polymer. It is similar to amylopectin, being composed of alpha-glucose molecules, but it is larger and there are more alpha-1,6 links. This makes it highly branched, more soluble, and more easily hydrolized than starch.
Please mark brainliest!
Answer:
polysaccharides have coil and long branch while glycogen has short chain.
Explanation:
polysaccharides have coil and long branch while glycogen has short chain.

How could this statement be revised to make it a hypothesis? Fish meal is safer than artificial fertilizers, but it does not make plants grow. Fish meal is a better fertilizer than artificial fertilizer because fish meal is natural. Plants that are fertilized with fish meal will grow taller than plants that receive artificial fertilizer. Plants that receive artificial fertilizer will be better than plants that receive fish meal.
Just take out the fluff.
Plants that are fertilized with fish meal will be healthier for plants than the plants that receive artificial fertilizer.
Or make one of those If, Then, Because statements.
If a plant is fertilized with fish meal rather than artificial fertilizer, then the plants will be overall healthier because fish meal is natural compared to the artificial fertilizer.

If you use a cladistic approach (organizing taxonomic groups by clades) in grouping organisms together, the resulting classification scheme:
Answer:
The classification scheme is ancestor.
Explanation:
In cladistic approach is a type of classification in which organisms are classified on the basis of their common ancestor. Those organisms are placed in one group which have common ancestor and share same characteristics or which are evolved from a common ancestor. With the passage of time changes occurs within the body of organisms so these organisms are different from one another in physical structure but have a common ancestor.
What would you think would happen if you reduce the incubation time to 30 minutes?
Answer:
Enzymatic activities is usually efficient when it happens at an optimum temperature. This temperature aids its proper functioning and too much of heat could as well denature the enzyme.
When you reduce the incubation time of an enzyme to 30 minutes , the enzyme may or may not have enough time to reach the amount of free energy needed to drive the enzymatic reaction.

You are studying a population of ground squirrels. You trap 100 individuals and find 9 that have a light colored coat, and the rest have a dark coat. You know that light coat color is recessive in ground squirrels. Assume HWE.
The question is incomplete. Here is the complete question.
You are studying a population of ground squirrels. You trap 100 individuals and find 9 that have a light colored coat and the rest have a dark coat. You know that light coat color is recessive in ground squirrels. What is the allele frequency for the light coat allele and the dark coat allele? How many of the dark coated individuals do you expect to be heterozygotes at the coat color gene? Assume the population is at H-W equilibrium.
Answer: Allele frequency for light coat: q = 0.3;
Allele frequency for dark coat: p = 0.7;
There will be 42 heterozygote;
Explanation: A population in H-W equilibrium is a population which doesn't change from one generation to the next if there are no disturbing factors, as migration or mutation.
It follows the equation: [tex]p^{2}+2pq+q^{2}=1[/tex].
p represents the frequency of the dominant allele;
q represents the frequency of the recessive allele;
2pq represents heterozygote individuals;
The sum of frequencies of both alleles must be 1, i.e.: [tex]p+q=1[/tex]
For the population of squirrels:
Frequency of recessive allele[tex]q^{2} = \frac{9}{100}[/tex]
[tex]q = \sqrt{\frac{9}{100}}[/tex]
q = 0.3
Frequency of dominant allele[tex]p+q=1[/tex]
[tex]p=1-q[/tex]
[tex]p=1-0.3[/tex]
p = 0.7
Frequency of heterozygote2pq = 2*0.7*0.3 = 0.42
In a population of 100 individuals: 0.42*100 = 42
The allele frequency for the light coat is 0.3; for the dark coat is 0.7.
It is expected to have 42 heterozygote individuals in this population.

O blood is recessive to AB blood. What possible blood types could result from parents with O and AB Blood?
Answer:
Parents having blood type AB and O can produce offsprings having blood group A or Bbut not O
Explanation:
The possible blood type that could result in the offspring is it can be either A or b but not O as O is recessive.
What is blood?Blood is defined as a fluid that distributes oxygen and nutrients to cells while also removing carbon dioxide and other waste materials.
There are three types of blood cells.
RBC - RBC stands for red blood cells. They are defined as a kind of blood cell present in the blood that is produced in the bone marrow. WBC - WBC is also called white blood cells. They are defined as a kind of blood cell present in the blood and lymph tissue that is produced in the bone marrow.Platelets - Platelets are defined as the cells that circulate in our blood and link together when they detect damaged blood arteries.Thus, the possible blood type that could result in the offspring is it can be either A or b but not O as O is recessive.

Determine what organism fits the following niche: Heterotroph, non-motile, spores.
A. Ferns
B. E. coli bacteria
C. Fly Cap mushroom
D. Arctic Hare
Answer:
C. Fly Cap mushroom
Explanation:
All fungi are heterotrophic organisms because they obtain food and energy from external sources. Moreover, fungi are non-motile since they don't move. Finally, these organisms produce both sexual and asexual spores which are dispersed by wind and water.
On the other hand, the mushroom is the body of a fungus that grows on the soil, generally in humid and shady areas. The fly agaric mushroom is one of the most recognizable species of fungus.
In the Landolt-C acuity test, the average threshold for accurately identifying the position of the gap in the C-like character was 0.75mm in size, at a distance of 3000mm. What angle is subtended by the gap at this acuity threshold? Show your working and give your answer in Minutes of arc.
Answer:
0.859 minutes of arc
Explanation:
The arc length for a given radius and angle in radians is ...
s = rθ
So, the angle is ...
θ = s/r
For the given geometry, the angle in radians is ...
θ = (0.75 mm)/(3000 mm) = 0.00025 radians
In minutes of arc, this is ...
(0.00025 radians)(60 minutes/degree)(180 degree/(π radians)
= (0.0025)(60)(180)/π minutes
≈ 0.859 minutes
The angle subtended is about 0.859 minutes of arc.

an insect population is growing in such a way that the number in each generation is approximately 1.5 times that of the previous generation. if there are 100 insects in the first generation, approximately how many insects will there be in the fourth generation
Answer:
Approximately 338
Explanation:
Since each generation of the insect is approximately 1.5 times that of the previous generation. Therefore,
Population of insect in the first generation = 100
Population of insect in the second generation = 1.5 × 100
= 150
Population of insect in the third generation = 1.5 × 150
= 225
Population of insect in the fourth generation = 1.5 × 225
= 337.5
The population of insect in the fourth generation is approximately 338.

Need Help!!! 30 points! You are monitoring coral growth on a specific site for several months. Over time, you notice that some of the coral colonies are beginning to turn white and die. What process could you infer is happening on the coral reef site?
(A) The coral reef is experiencing succession, so over time the coral will continue to die off gradually as the zooxanthellae algae leaves the coral polyps.
(B)The coral reef is experiencing succession, so the coral will continue to die off quickly as the zooxanthellae algae leaves the coral polyps.
C) The coral reef is experiencing climate change, so the rise in ocean temperatures is causing the coral to bleach as the zooxanthellae algae leaves the coral polyps.
(D) The coral reef is experiencing climate change, so the coral will die off from seasonal variation, which has no impact on zooxanthellae algae in the coral polyps.
Answer:
B) The coral reef is experiencing succession, so the coral will continue to die off quickly as the zooxanthellae algae leaves the coral polyps.
The coral reef is experiencing succession, thus as the zooxanthellae algae departs the coral polyps over time, the coral will continue to gradually die off. Therefore, option (B) is correct.
What is succession in coral reefs?When several living things in a particular area undergo succession, it doesn't matter what time of year it is. The destruction of a portion of a shallow reef by a boat might be one of the numerous instances of succession in coral reefs seen all over the world.
Since the coral reef is undergoing succession, when the zooxanthellae algae leave the coral polyps, the coral will continue to quickly decline. The coral is bleaching as the zooxanthellae algae leave the coral polyps as a consequence of climate change harming the coral reef. Seasonal changes will cause the coral to die off since the coral reef is experiencing climate change. The coral polyps' zooxanthellae algae are unaffected by this.

Even though adaptation was a topic of discussion among scientists before the 1800s, Charles Darwin and Alfred Russel Wallace did not create the theory of natural selection until then.
Wallace thought that adaptation of organisms to shifting environmental conditions was somehow related to the evolution of species. Wallace and Darwin both went beyond basic adaptation when formulating the notion of evolution by natural selection by describing how organisms adapt and evolve.
