describe how a supernova and neutron star are related?
Answer:
Neutron stars are one of the possible ends for a star. They result from massive stars which have mass greater than 4 to 8 times that of our Sun. After these stars have finished burning their nuclear fuel, they undergo a supernova explosion. ... It collapses so much that protons and electrons combine to form neutrons.

If green plant cells are incubated in the presence of CO2 molecules containing radioactive carbon atoms, the fate of the carbon atoms can be followed. In an experiment, radioactive CO2 was given for 1 minute to plant cells, and then the cells were examined after 1, 5, 10, 20, and 30 minutes. The following molecules were labeled with radioactive carbon at some point(s): glucose, glyceralde-hyde 3-phosphate, glycine (an amino acid), 3-phospho-glycerate, ribulose 1,5-bisphosphate, and sucrose.
Required:
List these molecules in the order in which they first become labeled.
Answer:
GlycineRibulose 1,5-bisphosphate3-phosphoglycerateGlyceraldehyde 3-phosphate.GlucoseSucroseExplanation:
The glycine, among other amino acids, helps to improve chlorophyll production and promotes the process of photosynthesis.
Calvin cycle
During the carbon fixation phase, a CO² molecule combinate with a ribulose 1,5-bisphosphate to form 6-carbonated molecules, which will divide into two 3-phosphoglycerate molecules.
During the reduction phase, NADPH donates its electrons to reduce 3-phosphoglycerate molecules, and turn them into glyceraldehyde 3-phosphate.
During the regeneration phase, a glyceraldehyde 3-phosphate molecule leaves the cycle and goes to the cytosol to form glucose. This step can be done when three CO² enter the cycle and produce six glyceraldehyde 3-phosphate molecules. One of them leaves the cycle to form glucose, while the other five are recycled.
Cytosol:
Once in the cytosol, glyceraldehyde 3-phosphate molecules are used to form glucose and fructose. These two molecules are the monosaccharides that form the sucrose.
Once sucrose is formed, it is transported from the photosynthetic tissues to different parts of the plant by the phloem.
1. What happens to oppositely charged atoms?

Which of the following is NOT involved in photosynthesis or cellular respiration?
a
cytokinins
b
chlorophyll
c
carbon dioxide
d
water
Answer:
a
Explanation:
Cytokinins are not involved in photosynthesis or cellular respiration. They are plant hormones that help regulate cell division and growth. On the other hand, chlorophyll, carbon dioxide, and water are all involved in photosynthesis and/or cellular respiration. The correct option is A.
What are Cytokinins?Cytokinins are plant growth hormones that stimulate cell division and delay senescence. They play a role in plant growth and development, but they are not involved in photosynthesis or cellular respiration. On the other hand, chlorophyll, carbon dioxide, and water are all involved in photosynthesis.
Chlorophyll is a pigment that absorbs light energy and converts it into chemical energy, while carbon dioxide and water are used to make glucose and oxygen through the process of photosynthesis.
Cellular respiration is the process by which cells convert glucose and oxygen into energy. Both carbon dioxide and water are produced as byproducts of cellular respiration. Therefore, all the options except cytokinins are involved in either photosynthesis or cellular respiration.
Therefore, the correct option is A.

which statement describes two organ systems working together to deliver nutrients to cells?
A. The excretory system removes excess nutrients from blood as it
makes urine.
B. The blood absorbs the nutrients that the digestive system obtains
from food.
C. The respiratory system transfers oxygen removed from nutrients
to the blood.
D. The molecules of important nutrients are made from food in the digestive system
Answer:
option B is the correct answer
Explanation:
the circulatory system and digestive system both are working to deliver food to each and every cell.
plz mark my answer as brainlist plzzzz.hope this will be helpful to you and plzzz.
B) The blood absorbs the nutrients that the digestive system obtains from food the two organ systems work together to deliver nutrients to cells.
The circulatory system and digestive system both are working to deliver food to each and every cell.
How do organ structures get meals to the cells?The digestive system converts the ingredients we consume into their simplest bureaucracy, like glucose (sugars), amino acids (that make up protein), or fatty acids (that makeup fat). The damaged-down meals are then absorbed into the bloodstream from the small intestine and the nutrients are carried to every mobile in the body.
These frame structures are all characteristic to maintain the cells in your frame: the circulatory, respiration, and digestive structures provide the nutrients and electricity your cells need to stay. The immune gadget protects these cells from pathogens.Your circulatory gadget, which consists of your coronary heart, blood, and blood vessels, is liable for transporting vitamins to the cells of your body. Particularly, nutrients are transported at some stage in your frame thru your blood thru capillaries, tiny blood vessels that join arteries to veins.
The cell consists of three components: the cell membrane, the nucleus, and, between the 2, the cytoplasm. In the cytoplasm lie complicated arrangements of first-class fibers and loads or maybe hundreds of minuscule but awesome structures known as organelles.

A cross between a plant with red flowers (R = dominant) and a plant with white flowers (r = recessive) yielded 47 plants with red flowers and 51 plants with white flowers. What are the genotypes of the parent plants? Explain.
A. The results are close to a 1:1 ratio of plants with red flowers to plants with white flowers. Therefore, the genotypes of the parents are Rr and rr.
B. The results should yield plants with red flowers and plants with white flowers in a 3:1 ratio due, so the geneotype of each parent is Rr. The number of offspring was not large enough to produce the expected results.
C. The results differ from the predicted values. Therefore, the genotypes of the parents cannot be determined.
D. The results should show a ratio of 3 plants with white flowers to 1 plant with red flowers, so the genotypes of the parent plants are RR and rr.
Answer:
A. The results are close to a 1:1 ratio of plants with red flowers to plants with white flowers. Therefore, the genotypes of the parents are Rr and rr.

In the morning, Jorge watched a cartoon about a sarcastic rabbit. Later, in his psychology class, he viewed
the image above and readily identified it as a rabbit instead of a duck. Which of the following best explains
this phenomenon?
Answer:
The correct answer is - priming.
Explanation:
Priming is a phenomenon that explains the behavior of an individual when an individual experiences a certain stimulus that influences response to a subsequent stimulus, unknowingly of the connection. This effect is known as the priming effect.
In this case, watching a cartoon of a rabbit acts as the stimulus that influences the response of identifying the image of duck as a rabbit. He is experienced priming effect.
