Answer:
The events in the order are,
G. PCO2 increases in blood.
H. CO2 produces H+ by reacting with water.
F. Extracellular fluid surrounding brain decreases in pH.
I. Central chemorEceptors are stimulated.
A. Medullary respiratory centers are stimulated.
C. Somatic motor impulses are senT to respiratory muscles.
D. diaphragm and external intercostal muscles contract at a faster rate.
E. More CO2 is exhaled.
B. CO2 levels in blood decline.
j. pH of brain extracellular fluid returns to normal.
Explanation:
In physiological events that take place in modulating respiratory rate is a compensatory mechanism occurs in the case of respiratory acidosis. In respiratory acidosis, carbon dioxide level increases in blood so the partial pressure of carbon dioxide will be higher.
The high amount of carbon dioxide is responsible for the formation of the bicarbonate and hydrogen ion this process continues, which decreases the normal pH. Chemoreceptors sense this change that activates the respiratory centers. and sends motor signals for the contraction of inspiratory muscles, which increases the rate of respiration.
The correct order of events in listed above.

In fruit flies, eye color is a sex-linked trait. Red is dominant to white.
What are the sexes and eye colors of flies with the following genotypes:
Look at the picture
30 points and braininess
Answer:
The correct answers are:
1 a. X^RX^r - red eye color female
b. X^RX^R - red eye color female
c. X^RY - red eye color male
d. X^rY - white eye color male
e. X^rX^r - white eye color female
(2nd part can also be answered by above)
Explanation:
It is given that the eye color is a sex-linked character where Red eye color is dominant over white eye color in fruit flies. Sex-linked characters are the character that is a similar inheritance pattern except in the case of the male as there is a Y chromosome that does not carry the gene for the eye color trait so the trait will depend on the allele present on a single X chromosome in males.
On the basis of this, the sex and color of eyes will be:
a. X^RX^r - red eye color female - Dominant character will mask the recessive white color and two copies of X which means female.
b. X^RX^R - red eye color female - both copies are dominant so red-eye color will be expressed and two copies of the X chromosome that means female
c. X^RY - red eye color male - One X and one Y chromosome that means male and only dominant allele present so red eye color.
d. X^rY - white eye color male - Only allele that is present is recessive with one Y chromosome that means male with white eye color.
e. X^rX^r - white eye color female - two X chromosomes with recessive allele which means white eye color female.
Dominance refers to when an allele masks the effect of another allele.
Red is dominant to white
The sexes and eye colors of flies with the following genotypes:
XR Xr - Female with red eyes.
XR XR - Female with red eye
XR Y - Male with red eye
Xr Y - Male with white eye
Xr Xr - Female with white eye
White eyed male - Xr Y
white eyed female - Xr Xr
Red eyed female (heterozygous) - XR Xr
Red eyed male - XR Y
White eyed female XrXr and red eyed male XRY
Xr Xr
XR XRXr XRXr
Y XrY XrY
The cross shows 50% red eyed female and 50% white eyed male.

What is the difference between backbone and spinal cord?
Explanation:
Spinal Cord is the tube-like structure which consists of bundles of nerve fibers. It is covered by the meninges and is surrounded by the cerebrospinal fluid.
Backbone or the spinal column is the central axis of the skeleton in all vertebrates. In a newborn human, there are about 33 bones that make up the spinal column. By the time the newborn becomes an adult, the number of bones reduces to 24 as they fuse during normal growth and development.
Moreover, the spinal cord is protected by the spinal column. In this article, we shall explore more differences between the two:
Difference Between Spinal Cord and Backbone
Spinal Cord
Backbone
Composition
Made up of bundles of nerve fibers
The backbone is made of bones called vertebrae
Function
Spinal cord acts as pathways for communication between the brain and the body
The backbone serves to provide structural support as well as support the body’s weight. It is also tasked with protecting the spinal cord
Segments
The spinal cord forms 31 segments, which are divided into 8 cervical nerves, 5 lumbar nerves, 12 thoracic nerves, 1 coccygeal nerve and 5 sacral nerves
The backbone can be split into 5 major segments – the cervical spine, the thoracic spine and the lumbar spine, sacrum and coccyx. Cervical spine is made up of 7 bones called vertebrae. Thoracic spine has 12 vertebrae and the lumbar spine and 5 vertebrae

MRNA strand: TATACGA
Answer:
The mRNA strand for TATACGA is UTUTGCT.
Explanation:
The DNA bases are adenine (A), thymine (T), guanine (G), and cytosine (C). Each of these bases pairs with a complimentary one. Adenine pairs with thymine, and cytosine pairs with guanine.
During transcription, the DNA is transcribed into an mRNA strand. The mRNA has the same complementary bases of the DNA strand, with the difference that instead of having adenine base the complementary base of thymine, it has uracil (U). When we interpret the DNA strand TATACGA, the mRNA will be adenine (A) paired with the DNA's thymine (T), uracil (U) paired with the DNA's adenine (A). Then the same sequence repeats itself. After that, guanine (G) pairs with DNA's cytosine (C), cytosine (C)pairs with the DNA's guanine (G), and lastly, thymine (T) with the DNA's adenine (A).

A cell with a diploid number of 2n = 8 undergoes mitosis. How many
chromosomes will EACH new cell have?
Answer:
8
Explanation:
Mitosis, a type of cellular division, involves the division into two daughter cells that are genetically identical to the parent cell. They are genetically identical in the sense that the daughter cells contain the exact same DNA sequence as the parent cell and also, the chromosome number does not change.
In this case, a cell is said to have a diploid number (2n) of 8 chromosomes. It will therefore, undergo mitosis to produce two daughter cells with 8 chromosomes each. For this reason, mitosis is called MULTIPLICATION DIVISION.

the Pummert squire to help you determine the probability for each color of
Sive the possible genotypes and phenotypes for the offspring
What percentage of the offspring would be yellow?
What percentage would be blue
What percenge would be onders green
Answer:
We know that the color of jellyfish is controlled by codominance inheritance pattern and yellow Y and blue B are two alleles and in case of heterozygous the goober or green color occurs then,
If Yellow jellyfish is crossed with goober, that is, YY X YB.
the punnett square will be -
Y Y
Y YY YY
B YB YB
The possible genotype of offspring will be YY, and YB and therefore, the possible phenotype of offspring will be Yellow, and Green. The Percentage of yellow offspring will be 50% as two out of four are dominant for Y allele and two heterozygous conditions that is 50 % and as there are two copies B alleles are not present so zero percent of blue color.
