Answer:
Explanation:
density=2.30 g/cm^3
volume=1000.0 cm*1000.0 cm*15.0 cm=15000000
now we know that
d= m/v
therefore
m=d*v
m=2.30*15000000
m=34500000 g
now we have to convert grams into kg
1kg=1000 g
34500000 g=34500000/1000
34500000 g=34500 kg

When the concentration of molecules on both sides of a membrane is the same, the molecules will
A move across the membrane to the inside of the cell
B stop moving across the membrane
C move across the membrane is both directions
D move across the membrane to the outside of the cell
Answer:
B. Stop moving across the membrane.
Explanation:
Movement of molecules across the cell membrane depends on the concentration of the molecules on both sides of the membrane i.e the higher the concentration of molecules,the higher the attraction,since the molecules have the same concentration on both sides of the membrane the molecules does not move to either of the sides.

There is a wide range of eukaryotic organisms including animals, plants, fungi, and protists, as well as most of the algae. Eukaryotic organisms may be either single-celled or multicellular.
Eukaryotic chromosomes are located within the nucleus of the cell, whereas the prokaryotic chromosomes are located in the nucleoid. This is the key difference between a prokaryotic and a eukaryotic cell. The eukaryotic cells have a membrane-bound nucleus whereas a prokaryotic cell lacks a well-defined nucleus.

Marisa is going to conduct an experiment to test a new anti-depressant medication. Some subjects will be taking the actual medication while others will take a placebo. Marisa is going to make this a single-blind experiment. What is one advantage of using a single-blind experiment in this study?
Answer:
One of the main advantages of using a single blind study in this case is that she will have uneffected people to compare to the ones who took the medicine
Explanation:
Using a single-blind experiment in testing the new anti-depressant medication offers the advantage of minimizing potential bias in the participants' responses, which could arise from their knowledge of whether they are receiving the actual medication or a placebo.
In a single-blind experiment, participants are unaware of whether they are receiving the medication or the placebo. This reduces the likelihood of placebo effect and experimenter bias. Participants' psychological and behavioral responses are more likely to be genuine and unbiased since they lack knowledge of their group assignment.
This strengthens the study's internal validity by improving the accuracy of evaluating the true effects of the anti-depressant medication without the influence of participant expectations or experimenter interference.

if a snake species were introduced to an ecosystem where it had no natural predators, what long-term effect do you predict the snakes would have on the population dynamics of the ecosystem?
They would breed with native snake species, resulting in an increase in biodiversity in the ecosystem.
They would serve as a food source for predators of native snakes, causing an increase in native snake populations.
They would form mutualistic relationships with native snakes, since they would occupy the same niche in the ecosystem.
They would compete with native snake species for resources, causing a decline in native snake populations and possibly extinction.
Answer:
D. They would compete with native snake species for resources, causing a decline in native snake populations and possibly extinction.
Explanation:
Just took the test! :D
They would compete with native snake species for resources, causing a decline in native snake populations and possibly extinction. Hence option D is correct.
What are predators?Predators are living things that go after and kill prey. Both carnivores and omnivores can be predators. Predation can be classified into four categories: carnivory, herbivory, parasitism, and mutualism. Depending on whether or not the victim dies, each sort of predation can be classified.
Predators include weasels, hawks, wolves, mountain lions, and grizzly bears. Because they are carnivores, predators only eat meat.
If a snake species were introduced to an ecosystem where it had no natural predators, it would compete with native snakes. Hence, option D is correct.

Sharks and whales are a classic example of two different animals revealing
similar traits in the same environment. One of the similarities of these two
marine animals is their habitat. They both live in the vast range of depth in
their environment. They also have the same fin structure. They only have a
single tail for propulsion and because they are both large aquatic animals,
they both consume large volume of food, however, sharks hunt for their
food. Whales do not have this hunting tendency. Another difference of
sharks to whales is their class. Whales are mammals while sharks are fish
but they both live in the ocean. Also, whales have bones while sharks only
have cartilages.
Answer: The similarities between shark and whales are indicative of convergent evolution.
Explanation:
Convergent evolution can be defined as the process in which the organisms are not closely related but they evolve similar traits as a result of living in a similar kind of environment or adapting traits which enable them to perform the same ecological niches.
The similarities between shark and whale is indicative of convergent evolution as the animals are not related to each other phylogenetically but they live in the same environment this they evolve same kind of traits.
The similarities between sharks and whales represent an example of convergent evolution.
Convergent evolution refers to the evolution of similar phenotypic traits in unrelated and/or distantly related species.Convergent evolution creates analogies, i.e., different structures that may have the same function but were not present in the last common ancestor of both species. On the other hand, divergent evolution refers to the development of dissimilar phenotypic traits in closely related species as a result of evolution by natural selection, thereby leading to speciation.In convergent evolution, similar phenotypic features (traits) have evolved independently and repeatedly in each lineage in order to adapt to particular environmental conditions.In conclusion, sharks and whales are an example of convergent evolution because they are distantly related species that exhibit similar phenotypic features in the same environment.
