Which statement correctly describes mitotic cell division?
Answer:
Explanation:
“Although part of your question is missing, you might be referring to this full question:
Which of the following correctly describes how mitosis and meiosis are similar?
A. Sister chromatids segregate to opposite poles of the cell during both mitosis and meiosis.
B. Crossing over occurs between homologous chromatids during both mitosis and meiosis.
C. Both mitosis and meiosis produce diploid daughter cells.
D. Both mitosis and meiosis produce genetically identical daughter cells.”
The statement that correctly describes how mitosis and meiosis are similar is “Sister chromatids segregate to opposite poles of the cell during both mitosis and meiosis”.
Mitosis and Meiosis both are classified under cell division that tends to take place in humans and certain other animals. Both Mitosis and Meiosis have both differences and similarities in the way they result in new cells with varying goals and slightly different outcomes. Some of the similarities between meiosis and mitosis are:
During both mitosis and meiosis, cells must duplicate their DNA and pull them apart into 2 sets and further place the sets on each end of itself and then divide down the middle part
Both meiosis and mitosis results in fresh new cells depending on the genes of their parent cells
Thus, we can conclude that the statement that correctly describes how mitosis and meiosis are similar is “Sister chromatids segregate to opposite poles of the cell during both mitosis and meiosis”. Hence, option A is the correct answer.

A growing community considers building a new hospital closer to residential neighborhoods. This will get residents to emergency care faster and save lives when it is
needed. The only land available near residential areas is a forested wetland that supports a variety of species. What is a social consequence of not using the land
for a new hospital?
Emergency care is farther away, risking the health and well-being of a growing community
Preserving the ecosystem may upset residents in a community with a hospital shortage.
O If the wetland is protected, residents have fewer environmental concerns about the area.
It protects the lives of species and prevents a reduction in carbon sequestering by the trees.
The social consequence of not using the land is that it will protect the lives of species and prevents a reduction in carbon sequestering by the trees.
A social consequence refers to any unforeseen event which can be positive or negative, experienced by a society and has an effect on them.
A positive social consequence benefits a group of the socially connected group and can also stimulate future purpose.
A negative social consequence has its repercussions and can be attributed to negligence and bad factors.
Conservation of the ecosystem is paramount as well as the survival of the community.
A positive social consequence from the given information is that if the forested wetland is preserved to support a variety of species, It will protect the lives of the species and prevent a reduction in carbon sequestering by the trees.
The community could have emergency ambulances to cater for the movement of patients in case of emergency to the hospitals or educate them on how to take good care of their health and how to minimize hazards at home and offices.

Explanation:
A student is researching the inheritance patterns of different traits in chickens. She hypothesizes that red feathers are dominant over black, and the trait for crests are dominant over non-crested. She performs a test cross to confirm her hypothesis. To produce the F1 generation, she crosses two parents-- a chicken that is homologous for traits showing red and crested and a chicken that is homologous for traits showing black and non-crested. Which ratio best represents the phenotype of the F2 generation
9:3:3:1
1:1:1:1
2:2:1:1
16:0
Answer:
9:3:3:1
Explanation:
In this inheritance pattern, the ratio that best represents the phenotype of the F2 generation is 9:3:3:1. Thus, the correct option for this question is A.
What is a Phenotype?A phenotype may be defined as the mechanism of expressing genotypes in the form of traits. In more simple words, it is also characterized as the morphology or physiology which comes due to the combination of alleles.
If a trait of red feathers is denoted by R and the trait of black feathers is denoted by r, then R > r. Similarly, a trait of crests is denoted by C and the trait of non-crested is denoted by c, then, C > c.
Now, RRCC is crossed with rrcc, the F1 offspring have the genotype RrCc with the phenotype of red feathers with crests. Now, RrCc is selfed, it produces the ratio of 9:3:3:1. This is an example of a dihybrid cross.
Therefore, in this inheritance pattern, the ratio that best represents the phenotype of the F2 generation is 9:3:3:1. Thus, the correct option for this question is A.

in humans, how does the circulatory system bring oxygen to every cell in the body?
Answer:
I found this in a science text, hope it helps.
Explanation:
"Blood from the heart is pumped throughout the body using blood vessels. Arteries carry blood away from the heart and into capillaries, providing oxygen (and other nutrients) to tissue and cells. Once oxygen is removed, the blood travels back to the lungs, where it is reoxygenated and returned by veins to the heart."
Basically, blood from the heart is taken away by arteries and then into capillaries, transferring oxygen to cells.
I hope I could help!
The circulatory system of human body brings about oxygen to the every cell by the help of blood. The heart of human body helps to pump up the blood with oxygen and makes it oxygenated.
What is the size of a human heart ?A size of a human heart is a size of a human fist it has 4 chambers where with 2 auricles and 2 ventricles. The auricles receive the oxygenated blood and the ventricles get the deoxygenated blood.
The human heart is bringing oxygen to the cells of the body where the oxygen combined with the Fe component that is iron of the blood and reaches every cell of the blood through the blood. Blood is transported to every cell of the body through the blood vessels.
Arteries carry the oxygenated blood and ventricles carry the deoxygenated blood where the blood that reaches the cellular level by the veins and the arteries along with the blood vessels that form a network.

in turkeys the allele for brown feather is dominant to the allele for a yellow feather. if two heterozygous turkeys mate and produce offspring, what is the probability of an individual offspring having yellow feather?
50%
0
25%
100%
Answer:
50%
Explanation:
trust me because the heterozygous is so weird but I know this.
In turkeys the allele for brown feather is dominant to the allele for a yellow feather. if two heterozygous turkeys mate and produce offspring, than the probability of an individual offspring having yellow feather is 50%. Thus, option A is correct.
What will be produced in turkeys a dominant gene?In turkeys a dominant gene, R, produces the familiar bronze color; its recessive allele, r, results in red. Another dominant gene, H, results in normal feathers; its recessive allele, h, produces feathers without webbing, so that they resemble tufts of hairs.
Two bronze turkeys with normal feathers were mated, and their offspring consisted of eight bronze with normal feathers, three bronze with hairy feathers, two red with normal feathers, and one red with hairy feathers.
Since, this offspring received a recessive red, r, allele from each parent and a recessive hairy, h, allele from each parent, both parents must heterozygous for both characters: RrHh.
Therefore, In turkeys the allele for brown feather is dominant to the allele for a yellow feather. if two heterozygous turkeys mate and produce offspring, than the probability of an individual offspring having yellow feather is 50%. Thus, option A is correct.
