Which of these statements about cell division is true?
A. Cells divide at random times
B. The phases of cell division can occur in any order
C. New cells formed by cell division can replace dying cells in an organism
D. A newly formed daughter cell has less DNA than its parent cell
Answer:
its gonna be D
Explanation:
It can't be A, since cells only divide once they are past interphase
It can't be B, becuase cell division does have an order
It can't be C, becuase a dying cell is still a functioning one
And it is D becuase daughter cells are haploid, while parent cells are diploid
Answer:
C. New cells formed by cell division can replace dying cells in an organism.

Which of the following describes a scenario that would result in the phenotypic change shown in the graph?
(please someone help )
C is the correct answer
This is an example of stabilizing selection in which there are selective pressure acting against the two extremes of a trait. This results in the intermediate trait to rise in frequency in the population
The graph given below shows the process of stabilizing selection, where the individuals have an intermediate phenotype increase in number. This scenario also refers to heterozygous advantage.
What do you mean by Phenotype?The phenotype may be defined as the appearance or manifestation of a specific character. It is also referred to as a trait.
In stabilizing selection, selection pressure is applied to both the extreme ends, which means the purebred characters possess selection pressure. And due to this the individuals with intermediate phenotypes are more favored.
Therefore, the graph given below shows the process of stabilizing selection.

How did researchers try to change the avian flu virus to make it more easily spread between humans?
Answer:
They did not try to do this.
Bird flu, when it first crossed over to humans, was not human to human transmissible.
But as a virus evolves, we expect sooner or later that it would get that ability.
Researchers do not need to try to get evolution what evolution would do all by itself anyway.
I know that very often the people that say that the Chinese created a virus in a lab are also people that say that they do not believe in evolution.
Stop being a hypocrite about it.
No one was researching how to do this, no one needed to research how to do this because this is done naturally by natural evolution, and no one would want to do this for any reason.
When you accuse “researchers” of trying to do something that has no benefit to science then you accuse all science researchers when you lie about it.

Which statement is true?(1 point) Fossils can provide information about the entire evolutionary process of life forms. Fossils cannot provide information about life cycles and behaviors. Fossils can provide information about when life forms existed. Fossils cannot provide information about relatedness of life forms.
Answer:
Fossils can provide information about when life forms existed.
Explanation:
got it right on the quick check. this is for connexus!
Fossils can provide information about the entire evolutionary process of life forms.
Fossils can provide information about when life forms existed.
Fossils are the undecayed remains of the once living organisms. These remain preserved inside the heap of sediments. The deeper the strata the oldest is the organism once existed. This is indicative of the evolution of the organism from the ancestor to the modern day organisms.Hence, fossils provide information related to the evolutionary process.

Sickle cell anemia illustrated in the picture below is the result of a mutation. What is the likely cause of this genetic mutation?
There's no picture.
Sickle cell anemia results from a mutation in a gene called HBB, which contains the blueprint for cells to make part of a protein called hemoglobin. The hemoglobin protein is made up of two alpha chains and two beta chains.
Sickle cell anemia is the result of a point mutation, a change in just one nucleotide in the gene for hemoglobin. This mutation causes the hemoglobin in red blood cells to distort to a sickle shape when deoxygenated. The sickle-shaped blood cells clog in the capillaries, cutting off circulation.

19. Use a Punnett Square to simulate a Bb x Bb cross between two flowers.
What is the probability that one of the offspring from that cross will have only the b factor:
a. 50%
b. 75%
c. 100%
d. 25%
25 % is the probability that one of the offspring from that cross will have only the b factor. So, the correct option is (D).
What is Punnett Square?
A Punnett square is defined as a specialized tool derived from the laws of probability that is used to predict the likely offspring from a cross or mating between two parents.
An example of a Punnett square which is shown in the attached image shows the results of a cross between two purple flowers, each with a dominant factor and a recessive factor.
Only one in four plants or 25% of the plants had white flowers (bb) containing only b while The other 75% have purple flowers (Bb, Bb), because the purple factor (B) is the dominant factor. This shows that purple color is the dominant trait in the plant.
Thus, 25 % is the probability that one of the offspring from that cross will have only the b factor. So, the correct option is (D).

The classification system for organisms has changed from seven levels to eight. This happened because
scientific consensus changed as scientists learned more about organisms.
scientists did not test the seven-level system often enough to lead to consensus.
the eight-level system of classification is an emerging idea that needs more testing.
the seven-level system of classification was not supported by scientists.
Answer:
scientific consensus changed as scientists learned more about organisms.
Explanation:
The classification system for organisms has changed from seven levels to eight level of classification system because scientists learned more about organisms. This new learned information allow scientists to change the existing classification system. When the scientist find new species that may have to change classification systems in order to accommodate them and placed them accurately in the classification system.
