IN AN ARCTIC ENVIRONMENT, A POLAR BEAR POPULATION WILL INCREASE AS A BLACK
BEAR POPULATION
Answer:
NO
Explanation:
Answer:
Decrease
Explanation:
Black bears are not well evolved to survive in arctic temperatures like polar bear are so the population of black bears in that area would probably decrease until it is wiped out because they can't survive there.

Describe what changes were made to historical cell theory and explain why these changes were
made.
what is a genotype
Answer:
In a broad sense, the term "genotype" refers to the genetic makeup of an organism; in other words, it describes an organism's complete set of genes. Humans are diploid organisms, which means that they have two alleles at each genetic position, or locus, with one allele inherited from each parent.
examples-Hair color. Height. Shoe size, the colour of your pupils etc.

In vesicular transport, __________ transport materials into and out of the cell using _______.
Endocytosis and exocytosis transport materials into and out of the cell using vesicles.
Endocytosis is called the process by which cells incorporate into them molecules, large or small, which are covered by the formation of a vesicle that detaches into the cell, forming phagocytic vesicles.In exocytosis, the proteins or molecules produced in the endoplasmic reticulum are wrapped in a vesicle towards the Golgi apparatus, where they are released to be used by other cells or by the body in different processes.Therefore, we can conclude that exocytosis and endocytosis are the biological processes responsible for the transport of particles and substances into and out of the cell.

A trilobite fossils has been used to tell us how life on earth has changed. Trilobite fossils are examples of?
A:mold and cast fossil
B:index fossil
C:trace fossil
D:petrified fossils
Answer:
B:index fossil
Explanation:
The trilobite fossils are examples of index fossils.
Index fossils are most desirable for stratigraphic construction and to predict ancient life forms on earth.
Index fossils are fossils with the following characteristics;They have short stratigraphic spanThey have a wide geographic distributionShows rapid evolutionary trends or changes.Trilobite is one of such fossils that have the above listed properties.
In the cells of most organisms, genetic information is contained in the:
A cell wall
B nucleus
C organelle
D all of the above
Answer:
The nucleus
Explanation:
Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA). Mitochondria are structures within cells that convert the energy from food into a form that cells can use.

What changes during a controlled experiment? A. A variable B. The results C. The conclusion D. The hypothesis
Answer:
Option B
Explanation:
The answer is option B or "the results." Wouldn't be option A because a variable depending on the type is tested during a experiment if you change the variable you have a whole other experiment going on, it wouldn't be option D because your hypothesis is a logically guess at the beginning of a experiment of what you think is going to happen and it doesn't change. It wouldn't be option C because the conclusion is at the end of the experiment after you finished testing, recorded the results, and found out if your hypothesis is correct meaning it doesn't change, leaving option B as your answer.
Hope this helps.
