Suppose a species lives in an ecosystem with unlimited resources and no predators. What is the shape of its population versus time graph? help ASAP
Answer:
D. a curve that increases exponentially as time passes
Explanation:
I just took the test
A population growth curve that increases exponentially as time passes would result if a species has unlimited resources and no predators.
Exponential population growthExponential population growth occurs when a population is capable of reaching its biotic potential.
With unlimited resources and a lack of predators, the population of a species continues to grow exponentially without any hindrance. This result is a J curve.
With limited resources, the population might increase exponentially initially and will level off as the carrying capacity of the ecosystem is reached.

What is the role of the enzyme dna polymerase in dna replication?.
Answer:
DNA polymerase a type of enzyme that is responsible for forming new copies of DNA, in the form of nucleic acid molecules.
Explanation:
How does an enzyme’s active site relate to its substrate?
Answer:
A substrate enters the active site of the enzyme. This forms the enzyme-substrate complex. The reaction then occurs, converting the substrate into products and forming an enzyme products complex. The products then leave the active site of the enzyme.

Which of the following can you infer from the information in the table below? Hominid species Evidence H. Neandertalensis Physical features include skeleton suited for upright walking, hands, and large brains. Burial sites contain artifacts like flowers, food, and weapons. All fossils found have been radiocarbon dated to be 130,000 to 35,000 years old. H. Sapiens Walk upright, have thumbs used for making tools. Large brains Bury their dead ceremonially. Fossils found in sediment layers containing volcanic ash crystals that are 195,000 years old H. Neandertalensis and H. Sapien were able to mate and produce offspring. H. Neandertalensis is not a direct ancestor of H. Sapien. H. Sapien is a hominid branch that will become an evolutionary dead end. H. Sapien and H. Neandertalensis did not occupy the same geographic region.
We can infer from the information in the table below information about the evolution.
Evolutionary History of Modern Man1) Modern shares a common ancestor with gorillas and chimpanzees.
2) Some species before sapiens sapiens, according to the evolutionary process, are:
AustralopithecinesErgasterRectusNeanderthalensis and sapiens.3) Australopithecines inhabited the arboreal savannas of Africa around 2.8 to 2.3 million years ago.
4)Several species of australopithecines were able to walk upright or semi and had small brains.
5) During this period, Africa was undergoing a series of environmental changes that transformed its arboreal savannas, inhabited by australopithecines, into open savannas.
6) Thus, the australopithecines began to be exposed to predators, due to the decrease in shelters. This fact led to the extinction of most australopithecines.
Only a few lineages were able to adapt and survive, allowing the emergence of hominids.
With this information, we can know a little more about the evolution process of the human species.

what is pressure and how do we get it
Answer:
pressure, in the physical sciences, the perpendicular force per unit area, or the stress at a point within a confined fluid. ... In SI units, pressure is measured in pascals; one pascal equals one newton per square metre. Atmospheric pressure is close to 100,000 pascals.
Calculating pressure
To calculate pressure, you need to know two things:
Pressure is calculated using this equation:
pressure = force ÷ area.

PLEASE HELP!!!! WILL MARK BRAINLIEST!!!!
Answer:
yes, these are isotopes of nitrogen.
Explanation:
Any atom with the same number of protons, but a different number of neutrons is called an isotope. Nitrogen has 7 protons and 7 neutrons. If it had a different number of protons, it would be a different element. Since we know both elements A and B are Nitrogen and therefore both have 7 protons, that means they have 8 and 9 neutrons, respectively. Therefore, they are isotopes of Nitrogen.
