stages of mitosis
Interphase: In this stage , nothing really happens in the cell, resting stage of the cellprophase: in this stage , the chromatins condenses into chromosomes, the nuclear membrane disappear and the spindle fibre radiates
metaphase: in this stage , the chromosomes align in the middle and meet at the equatoranaphase: the chromosomes split at the centromere and move to the opposite polestelophase: the cell splits, and the spindle fibre disappears cytokinesis: the cell produces two daughter cellsTwo biological processes that occur in certain organelles are represented in the diagrams below.

The best example of a hypothesis leading to new experimental methods is that the Thomas Hunt Morgan continued the genetic research of Gregor Mendel, but Morgan used fruit flies.
Through Thomas Hunt Morgan's fruit fly experiments, he was able to discover and notice the inheritance of specific chromosomes. This experiment gave Mendel a great opportunity to publicize his idea of studying humans.
Therefore, The Purple Sea Urchin obtains oxygen through diffusion only the diffusion of oxygen into the organism. Also, oxygen diffuses from the canals into the rest of the body and carbon dioxide diffuses back into the canals to be released.

In many parts of the United States, homeowners use a significant portion of their energy budget to heat their home in the winter. It has been determined that lowering a thermostat by 3°F in the winter can reduce the energy costs by about 10 percent in many homes. An individual homeowner lowers their thermostat by 3 degrees exactly halfway through the billing period. For the month that the thermostat was lowered, the heating bill was $95. How much money did the family save in the month in which they lowered the thermostat setting halfway through the billing period?
Answer:
B. $5
Explanation:
$95/10 percent = 9.5
9.5/2 (because it is halfway through the billing period) = 4.75
4.75 rounded up to the nearest tenths place is 5.
A billing period is a duration of time that starts from the last closing date of the statement of the specific invoice. The billing amount fluctuates according to the usage of the services taken or used.
$5 will be saved by the family in a month when they lower the thermostat setting halfway through the billing period.
The amount can be estimated by:Given,
The heating bill when the thermostat was lowered = $95Reducing thermostats can reduce energy costs by = 10%10% of the total bill will be:
[tex]\dfrac {\$95}{10\%} = 9.5[/tex]
Divide the value by 2 because the thermostat was lowered in the middle of billing time.
[tex]\begin{aligned} \dfrac{9.5}{2} & = 4.5\\ &= \$ 5\end{aligned}[/tex]
Therefore, 5$ was saved by the family.

Phillip Gingrich finds an S-shaped bone in this partial skull, a sigmoid process, which is unique to
one particular order of animals in the water today... which one?
Answer:
A primitive whale which he named Pakicetus.
Explanation:
Philip Gingrich is a vertebrate paleontologist at the University of Michigan. He has performed extensive research on whales at the Egyptian desert of Wadi Hitan. His research team member discovered a skull whose braincase was bigger than that of a walnut. Gingerich was able to link the small-brained animal, to an early whale.
The auditory bulla had an s-shaped bony crest known as the sigmoid process and these two features helped whales to hear in water. The case, however lacked other features that helped whales hear beneath the waves. This led Gingrich to the conclusion that the unknown animal was semi-aquatic. This finding also lent credence to the possibility of whales evolving from terrestrial animals.

When blood is flowing through a vena cava, which main blood vessel will it flow through next?
A hepatic portal vein
B hepatic vein
C pulmonary artery
D pulmonary vein
Answer:
C.
Explanation:
When the ventricle is full, the tricuspid valve shuts. This prevents blood from flowing backward into the right atrium while the ventricle contracts.
As the ventricle contracts, blood leaves the heart through the pulmonic valve, into the pulmonary artery and to the lungs, where it is oxygenated.
Why do you only need one copy of a dominant trait gene to have that trait?

Answer:
d
Explanation:
d
The monkey and gorilla are the most closely related organisms with the fewest differences in their amino acid sequences. Hence option d is correct.
What are amino acid?Amino acid is defined as any of the elements present in both plants and animals that come together to produce a substance (protein), which is essential for a healthy body and for growth. The metabolism of amino acids plays a crucial role in many biological processes that take place inside the human body.
An examination of the first complete sequence of the gorilla genome suggests that humans and gorillas last coexisted 10 million years ago. The gorilla is the last of the surviving great apes, including humans, chimpanzees, orangutans, and gorillas, whose entire genetic sequence has been compiled.
Thus, the monkey and gorilla are the most closely related organisms with the fewest differences in their amino acid sequences. Hence option d is correct.

A confounding variable is an outside variable beyond the control of the race teams and official. What are some confounding variables that could contribute to the speed of the tracks?
Answer:
rain and turns
Explanation:
There are various confounding variables that could contribute to the speed of the track, one of which is rain. Rain is something that the race teams and officials cannot control and affects the speed at which racecars can operate on a track. This is because the Rain wets the tracks which prevents the cars wheels from properly gripping the track and instead causes them to skid. Another confounding variable would be turns. A track that has more turns would drastically decrease the speed of the tracks as cars would need to slow down for each turn.
pls help how do i compare the aspect of an autograft to that of an allograft
Answer:
The correct answer is - A patient's own tissue - an autograft and tissue from another person - an Allograft.
Explanation:
If the bone or the tissue is transferred from one point of the body to another point of the same person's body, this is called an autograft and is also thought of as "gold standard". It has a low level of risk in comparison to other grafts. It is used for surgical reconstruction.
An allograft is the transfer of the tissues or bone of an individual to the body of another individual of the same species during the surgical process. This type of graft has some risk of compatiblity.

In humans, brown eyes (B) is dominant over blue eyes (b). Teddy has brown eyes, his mother has brown eyes and his father has blue eyes. Their punnett square is represented in the picture attached:
Teddy says that all 4 children in his family have brown eyes. Is this possible?
Question 12 options:
a. Yes, because every child has a 50% chance of having brown eyes
b. No, they should be half brown eyes and half blue eyes
c. No, at least one of his siblings should have brown eyes
Answer:
A. Yes, because every child has a 50% chance of having brown eyes
Explanation:
This is the correct answer
According to the Punnett square that is given below, the argument made by Teddy may not have correct evidence. This is because it is not possible to have all 4 children in his family has brown eyes. So, the correct option for this question is B.
What is Punnett square?A Punnett square may be characterized as a type of table in which all of the plausible consequences for a genetic cross between two individuals with known genotypes are given.
According to the context of this question, the genotype of the mother is Bb which has a brown phenotype because brown eye (B) is dominant over blue eyes (b). While the genotype of the father is bb. This is blue eyes.
When both these genotypes are crossed, the genotypes of offspring are Bb, Bb, bb, and bb. This means that the individuals have both traits of blue and brown phenotypes by 50% each.
Therefore, the correct option for this question is B.
