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

Explanation:

Prior to being able to sequence DNA, organisms were described and categorized solely by their distinct morphologies (physical characteristics) and ecological roles.  The ability to sequence DNA has revealed a great deal more about where an organism belongs taxonomically and helps pinpoint new species.  DNA is now used alongside morphology and ecology to substantiate an organism’s distinctiveness in the biological world.

Consider the image of our solar system. Based on your knowledge of gravitational attraction, which planet has the largest gravitational force? A) Earth B) Jupiter C) Mercury D) Neptune

Answers

Answer:

Jupiter

Explanation:

Jupiter is the fifth planet from our Sun and is, by far, the largest planet in the solar system – more than twice as massive as all the other planets combined. Jupiter's stripes and swirls are actually cold, windy clouds of ammonia and water, floating in an atmosphere of hydrogen and helium. Jupiter’s iconic Great Red Spot is a giant storm bigger than Earth that has raged for hundreds of years.

With a radius of 43,440.7 miles (69,911 kilometers), Jupiter is 11 times wider than Earth. If Earth were the size of a nickel, Jupiter would be about as big as a basketball.

From an average distance of 484 million miles (778 million kilometers), Jupiter is 5.2 astronomical units away from the Sun. One astronomical unit (abbreviated as AU), is the distance from the Sun to Earth. From this distance, it takes Sunlight 43 minutes to travel from the Sun to Jupiter.

Jupiter, because it’s the largest and most massive in our solar system.

How could the notion of maximum parsimony lead to an error in establishing an evolutionary relationship

Answers

Answer:

The notion of maximum parsimony does not consider the entire evolutionary history, being able to suppress important evolutionary points that would cause errors in the evolutionary relationship of a species.

Explanation:

Maximum parsimony is a criterion for optimizing phylogenetic trees. This is because through this criterion an analysis is made of all possible phylogenetic trees of a species, observing which one is smaller and offers simpler and summary information. On the one hand, the study of the smallest phylogenetic tree can be faster and more understandable, since its information is basic and direct. However, maximum parsimony can lead to errors in the establishment of an evolutionary relationship of a species, because it suppresses the entire history of evolution of that species, being able to suppress really important points in one of the clades, which would result in an incorrect evolutionary conclusion.

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

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.

stion 6/48which would be the best evidence that a cell is using active transport to move a substance across its cell
membrane?
A) Substances are moving rapidly across the cell membrane.
B) ATP is being rapidly consumed near the cellular membrane.
C) Substances are moving from high to low concentrations.
D) Substances are moving through channels in the cell membrane.

Answers

Answer:

B) ATP is being rapidly consumed near the cellular membrane.

Explanation:

Active transport is a form of transport used by living systems in which substances/molecules move across a membrane from a region where they are less concentrated to a region where they are highly concentrated. This movement occurs against the concentration gradient, hence it requires energy in form of ATP in order to occur. The transport is said to be "ACTIVE" if it is energy consuming.

Hence, based on the explanation above, the best evidence to showcase the occurrence of active transport in a cell is the rapid consumption of ATP near the cellular membrane. ATP will be used to pump needed substances into the cell via the cell membrane, serving as the semi-permeable membrane.

It has to be A because active transport happens faster than passive transport.
