You wish to study the impact of synthetic estrogen like hormones on the health of whales (and people). Select the organism from the table below that would be best to use in your research. Why did you select this organism?


Model Organism Characteristics

Yeast------------------Single celled, eukaryotic (contains a nucleus)
Fruit fly---------------Multicellular, eukaryotic, invertebrate, arthropod
Zebrafish-------------Multicellular, eukaryotic, vertebrate, fish
Mouse-----------------Multicellular, eukaryotic, vertebrate, mammal


Fruit flies, because they are multicellular like whales
Mouse, because they are mammals like whales
Yeast, because they are eukaryotic like whales
Zebrafish, because they live in the water like whales

Answers

Answer 1

Answer:

Because humans are multicellular, eukaryotic (contains a nucleus), vertebrates, and mammals, the best organism to test the synthetic hormones on would be a mouse.

Explanation:

Humans and whales are multicellular (they have many cells) and their cells are eukaryotic (contain a nucleus). They also have a backbone (spinal column), which makes them a vertebrate. Finally, all humans and whales are mammals. Therefore, to get the best results, the testing should be performed on a mouse.

Performing the experiment on yeast would give good results for singular-celled organisms, like protozoa.Performing the experiment on a fruit fly would give good results for multicellular invertebrates, like spiders.Performing the experiment on zebrafish would give good results for all fish in general.

Answer 2
The answer is a mouse

Answers

Answer:

ttrace

Explanation:

A trace fossil is evidence of an organism, but is not made of the organism itself.

What is Trace fossil?

The structure and behaviors of an organism, rather than its physical form, are used to classify trace fossils. A few of the trace fossils discovered in Denali have been connected to body fossils discovered in rocks from the North Slope or Talkeetna Mountains that are of a comparable age.

These connections provide investigators access to identities that are more certain than those known solely from trace fossils.

Bird tracks near probe marks in the earth suggest that the birds were using their beaks to dig for food. Invertebrate burrows located in the same rocks possibly provide the answer to what good food the birds were eating.

Therefore, A trace fossil is evidence of an organism, but is not made of the organism itself.

You go on a trip to the Galapagos island to study the animals there for a paper you are writing on evolution, just like Darwin did. You spend 3 days taking notes on all the physical characteristics you can observe about the tortoises and then you spend 3 days observing the finches. What have you recorded? A. Inherited characteristics B. Environmental variation factors C. Phenotypes D. Genotypes

Answers

Answer:

C. Phenotypes

Explanation:

Taking notes on all the physical characteristics observed about the tortoises and then observing the finches, I have observed the phenotypes.

Phenotypes are the observable characteristics of a species which are the result of genetic expression influenced by the environmental factors.

So, phenotypes will be recorded during the trip while taking notes on all the physical characteristics which can be directly related to genotype and environmental factors.

Hence, the correct option is "C. phenotypes".

The correct answer is C because the others don’t work

Sometimes, distinguishing the type of interaction between species in not straightforward. Remoras are fish that are often found attached to larger animals, such as sharks. The relationship between remoras and sharks is often described as a commensalism. Although this suggests that sharks do not benefit from this relationship, remoras sometimes consume parasites on their skin. Which of the statements below best supports the relationship being a commensalism?

Although remoras consume parasites, sharks with remoras show no better health or growth than sharks without remoras.

Although remoras consume parasites, they usually consume the flesh of the shark itself and harm it.

Remoras consume parasites, but sharks depend on parasites to remain healthy.

The fact that remoras consume parasites suggests that they provide a benefit, making this a commensal relationship.

Answers

Answer:

The commensal relationship between the sharks and remoras can be described as although remoras consume parasites, sharks with remoras show no better health or growth than sharks without remoras.

Explanation:

A commensal relationship refers to a relationship where two or more organisms in a habitat neither benefit or harm each other.

The second option infers that the remoras harm the sharks. This is a parasitic relationship.The third option infers that the sharks are harmed by the remoras because the sharks depend on something that the remoras are limiting. This is also a parasitic relationship.The fourth option infers a commensal relationship, but falsely describes it. The relationship described by this option is a parasitic relationship (one benefits, the other does not).

Therefore, the answer is the first option: Although remoras consume parasites, sharks with remoras show no better health or growth than sharks without remoras.

Answer:

it is A) Although remoras consume parasites, sharks with remoras show no better health or growth than sharks without remoras.

What effect will the settling of sediment have on the shape of the stream?

Answers

The issue of sediment in aquatic environments has been a topic of concern for many decades. During the nineteen-thirties, erosion became a national issue because of the dust bowl and as a result the Soil Erosion Service was established. Since the nineteen-thirties, the study of sediment erosion, transport, deposition, and intrusion has increased exponentially in the United States. Considering all of the past and current research, it is difficult to focus on essential research, but with limited resources it is imperative to refine the topics and prioritize the necessary areas of study. The same scoping is also true for treatment practices. The best and most effective treatment should be used on the most critical habitat. Establishing this systematic prioritization is a challenging but substantive endeavor.

Answer:

Question was : The graph in part A shows how slow-moving water cannot carry large pieces of sediment. As water slows down on the inside of a curve, some of the larger pieces of sediment will settle out of the water. What effect will the settling of sediment have on the shape of the stream?

Answer:

The river will deposit sediment along the inside of a bend in the river. This deposition causes the inside of the curve to become shallower and move farther inward

Answers

Answer:

B. Dehydration

Explanation:

Addition reaction is defined as the chemical reaction in which two different compunds combine together to form a new compund.

Dehydration reaction is defined as the chemical reaction in which water molecule (H2O) is removed from the reactant.

For example: RCO2H + R′OH ⇌ RCO2R′ + H2O

In the given equation: CH3OH + HOCH3 = CH3-O-CH3 + HOH

The reaction is showing dehydration because two molcules are combined aand  water molecule is eliminated from the reactant.

Hence, the correct option is B. Dehydration.

Which type of selection is the most likely to result in Speciation?
A. Stabilizing selection
B. Directional selection
OC. Disruptive selection
D. Artificial selection
Reset Selection

Answers

Answer:

C. Disruptive selection

Explanation:

Disruptive selection, also called diversifying selection, describes changes in population genetics in which extreme values for a trait are favored over intermediate values. In this case, the variance of the trait increases and the population is divided into two distinct groups. Two separate groups emerge.

Directional selection most likely to result in speciation. The correct option is B.

What is speciation?

Speciation is the process by which a new plant or animal species emerges. When a group within a species separates from other members of its species, it develops its own distinct characteristics.

Speciation is the evolutionary process by which new and distinct species emerge. Species evolve through genetic modification. The new species is reproductively isolated from the previous species, which means it cannot mate with it.

Apple maggot flies - Originally only laid eggs on hawthorn apples, apple maggot flies now lay eggs on both hawthorn apples and other domestic apples in the United States.

The speciation is caused by one of the reason known as directional selection.

Thus, the correct option is B.
