From fossil evidence, you know two species shared a common ancestor approximately 50 million years ago. In comparing a known neutral sequence between rats and mouse, you found 92 base differences in 1000bp. From this information, which of the following values is closest to what you would predict the mutation rate to be?
a. 1 x 10-9
b. 4 x 10-9
c. 2 x 10-9
d. 5 x 10-9
e. 5 x 10-8
f. 8 x 10-9
Answers
Answer:
Option c ([tex]2\times 10^{-9}[/tex]) is the correct alternative.
Explanation:
Given:
Common ancestor,
= 50 million years ago
Base differences,
= 92
Now,
The predicted mutation rate will be:
= [tex]\frac{92}{50\times 10^6\times 1000}[/tex]
= [tex]\frac{1.84}{10^9}[/tex]
= [tex]1.84\times 10^{-9}[/tex]
or,
= [tex]2\times 10^{-9}[/tex]
Thus the above solution is the right one.

which organ is responsible for helping to keep the water concentration equal on each side of the cell membrane?
(please help I've been stuck on this for 2 days)
Answers
Answer:
solute membrane
Explanation:
Kidney is the main organ which is responsible for helping to keep the water concentration equal on each side of the cell membrane.
What is Kidney?The kidneys are the main organs in the body which remove waste products and extra water from the blood in the form of urine and also help to keep the chemicals such as sodium, potassium, and calcium balanced in the body. The kidneys also secrete hormones which help control blood pressure and stimulate bone marrow to make red blood cells.
Kidneys maintain water concentration in the body. Kidneys maintain homeostasis through osmosis. Osmosis is the phenomenon of movement of water or fluid particles from a region of higher concentration to a region of lower concentration through a semi-permeable membrane.

Nebulae and stars are related in the following ways:
Stars explode to form nebulae.Stars form from nebulaeNebulae form from stars.Nebulae refer to a giant cloud that consists of gas and dust that are in space. They're bodies of clouds that are special. It should be noted that nebulae consist of helium, hydrogen, cosmic dust, etc. It should be noted that in some nebulae, there are stars that are formed from large clouds of dust and gas.In such a case, when some stars have been formed in the cloud, they'll then illuminate the cloud with their lights.In conclusion, it should also be known that when there is an explosion of a star that's dying, this then forms nebulae.

Which two stages are part of the cell cycle but not part of mitosis?
Answers
Answer:
Interphase is one of the two
Explanation:
Interphase is often included in discussions of mitosis, but interphase is technically not part of mitosis
The mitotic phase and inter phase are the two primary stages of the cell cycle. The cell develops and DNA replication occurs during interphase. The duplicated DNA and cytoplasmic components are segregated and the cell splits during the mitotic phase.
What are the different phases of the cell cycle?The four stages of mitosis are prophase (sometimes known as early prophase and prometaphase), metaphase, anaphase, and telophase. The mitosis movie contains more information about these phases. In cytokinesis, the cell's cytoplasm splits in two to create two new cells.A cell cycle is the sequence of events that occur in a cell as it grows and divides. A cell spends the majority of its time in what is known as interphase, where it grows, replicates its chromosomes, and prepares for cell division. The cell then exits interphase, goes through mitosis, and divides completely. Prophase, prometaphase, metaphase, anaphase, and telophase are the stages. Cytokinesis is the final physical cell division that occurs after telophase and is thus sometimes considered a sixth mitotic phase.To learn more about phase of cell refer to:

There will be a decrease in frequency for beak sizes labeled at point 2 on the graph.
The population of birds will change over time with regard to its beak frequency due to directional selection.
What is natural selection?
Natural selection is a mechanism of evolution that occurs when individuals with certain advantageous traits are more likely to survive and reproduce, passing those traits on to their offspring. This process leads to a gradual change in the genetic makeup of a population over time, as beneficial traits become more common and less advantageous traits become less common.
Natural selection occurs because resources in nature are limited, leading to competition for survival and reproduction. The individuals with traits that best suit them to their environment will have a higher chance of success, while those with less suitable traits are more likely to die or fail to reproduce. Natural selection is a key driver of evolution and is responsible for the diversity of life on Earth.

A virologist has a cell-free extract of herpes simplex virus (HSV) that has a titer of 6 x 106 infectious virus particles/mL. This virus forms plaques on monolayers of the monkey kidney cell line, CV-1. Following completion of a 10-fold dilution series, the virologist plates 100 microliters of each sample in duplicate.
Required:
What experimental results did he MOST LIKELY observe in the duplicate plates corresponding to his 1:10000 dilution?
Answers
Answer:
61 for Plate 1 ,
59 for Plate 2
Explanation:
Given that the original stock has a concentration of 6 * 10^6 infectious virus particles /mL
and it was diluted by 1:10000
New concentration = ( 6 * 10^6 ) / 10000 = 600 infectious virus particles/ mL
Also given that the virologist plates 100 mL of each sample
therefore; 0.1 mL has a count of 60.
The experimental results that he is most likely to observe in the duplicate plates will be ;

Difference between pure tone and speech audiometer
Answers
Answer:
Speech audiometry assesses your ability to hear and comprehend spoken words. ... They are also charted on an audiogram, which measures the decibel level, frequency and gravity of hearing loss.
Pure-tone audiometry only measures audibility thresholds, rather than other aspects of hearing such as sound localization and speech recognition. ... However, there are benefits to using pure-tone audiometry over other forms of hearing test, such as click auditory brainstem response pure tone audiometry, which only gives an indication of absolute perceptual thresholds of tonal sounds (peripheral function), whereas speech audiometry determines speech intelligibility and discrimination

The results showed that in 30 per cent of cases pre-operatively the speech audiogram suggested a significantly worse hearing ability than that suggested by the pure tone audiogram (PTA). Where a PTA gives a borderline threshold disproportionate parental concern should be taken seriously as the hearing ability may well be worse than the PTA suggests.
