In which stage of mitosis do the identical sets of chromosomes uncoil and resume their chromatin form?
In mitosis, chromosomes uncoil and resume their chromatin form in the telophase stage. This is when the nuclear envelope re-forms around the separate chromosome sets, which then uncoil into chromatin. Telophase is followed by cytokinesis.
Explanation:In the process of mitosis, the stage in which the identical sets of chromosomes uncoil and resume their form as chromatin is called the telophase. During this last phase of mitosis, the nuclear envelope begins to reform around the two separate sets of chromosomes now located at opposite ends of the cell. The chromosomes then uncoil, returning to their original loosely arranged chromatin form. This stage is followed by cytokinesis, the final part of the cell cycle, where the cell divides into two separate daughter cells, each having the same number of chromosomes as the original cell.

Victoria has a crate of vegetables that weighs 100 newtons. She exerts a force of 100 newtons to lift the crate with a pulley. What’s the mechanical advantage in this situation? less than 1 equal to 1 equal to 0 more than 1
Answer:
Option B , equal to 1
Explanation:
Mechanical advantage is the ratio of out force to the input force.
Here,
Input force (IF) [tex]= 100[/tex] newtons
Output force (OF) [tex]= 100[/tex] newtons
The mathematical relationship for mechanical advantage (MA) is as follows
[tex]MA = \frac{OF}{IF}[/tex]
Substituting the given values in above equation, we get
[tex]MA = \frac{100}{100} \\MA = 1[/tex]
Thus, mechanical advantage is equal to 1

CAM plants close their _____ during the day and open them at night.
The correct answer is stomata.
CAM plants they close their stomata during the day and open at night.
CAM is also known as Crassulacean acid metabolism. CAM is termed as a pathway for carbon fixation which evolves in some plants as an adaptation to conditions which are arid.
If a plant is using CAM in full then the stomata which is found in leaves remain closed during the day reason being it reduces evapotranspiration and at night it opens to collect carbon dioxide.
This carbon dioxide is being stored in vacuoles as four carbon acid malate at night whereby the malate is being transported to chloroplasts and converted back to carbon dioxide which is known to be used in the process of photosynthesis.

Two stars, star 1 and star 2 are at almost equal distances from earth
Star 1- 3.61 mass of star
Star 2- 3.59 mass of star
Which stamens is correct
A-Earth exerts almost equal gravitational force on both stars
B-earth exerts more gravitational force on star 1
C-star 1 attracts star2 with greater gravitational force than star 1
D-star 2 attracts star 1 with a greater gravitational force than star 1 attracts star 2
Answer:
Option B and C
Explanation:
The mass of star 1 is greater than star 2 and hence the gravitational force exerted by star 1 on star 2 is greater as compared to the gravitational force exerted by star 2 on star 1
As per the standard equation - gravitational force between two objects is equal to
[tex]= \frac{g* m_1* m_2}{r^2}[/tex]
This equation clearly states that the gravitational force exerted between any two objects is governed by the masses of these objects.
Thus, earth (with constant weight ) exerts more force on star1.
The oxygenated blood is returned to the left atrium of the heart by way of four vessels, two from each lung, known as the
The oxygenated blood returns to the left atrium of the heart via four pulmonary veins, completing the pulmonary circuit part of the mammalian double circulatory system.
The oxygenated blood is returned to the left atrium of the heart by way of four pulmonary veins, with two coming from each lung. After the blood has been oxygenated in the lungs via the pulmonary capillaries, it enters the pulmonary venules, which then lead to these larger vessels. These vessels are crucial in the cardiac cycle, as they complete the pulmonary circuit by delivering oxygen-rich blood back to the heart where it can then be pumped to the rest of the body through the systemic circulation.
The double circulatory system of most mammals, including humans, ensures that oxygenated and deoxygenated blood are efficiently circulated to the lungs and the body, respectively. The right atrium and ventricle take charge of sending deoxygenated blood to the lungs, while the left atrium and ventricle pump oxygenated blood to the rest of the body.

If the aortic semilunar valve is blocked, where would blood accumulate
If the aortic semilunar valve is blocked, blood will accumulate in the left ventricle of the heart.
Explanation:If the aortic semilunar valve is blocked, blood will accumulate in the left ventricle of the heart.
The aortic semilunar valve is located between the left ventricle and the aorta. Its main function is to prevent the backflow of blood from the aorta into the ventricle. If the valve is blocked, blood cannot flow properly into the aorta and will instead accumulate in the left ventricle.
This can lead to increased pressure and workload on the left ventricle, potentially causing symptoms such as shortness of breath, chest pain, and decreased functioning of the heart.

Gregor Mendel is best known for his work with pea plants and for helping uncover many of the mysteries of genetics. One of his major findings stated that there were specific, physical units of inheritance that are transmitted during reproduction. What is the the name given to these units of inheritance which can be found on chromosomes?
Answer: The correct answer is -
Genes.
Gregor Mendel worked with pea plants in order to find out the inheritance pattern of certain traits from parents to their next generation.
He proposed that for every characteristic in an organism, there are two basic factors (inherited from each parent).
These factors/units were later called genes (which are considered as unit of heredity) and are located on chromosomes.
Genes can be described as the segment of DNA that codes for a particular trait /characteristic of an organism.
For example - 'T' and 't' gene correspond to tall and dwarf height of pea plant respectively.
Thus, gene is the right answer.
