The Sun has been stable for 5 billion years. What will happen in the next two
stages of its life cycle?
A. First it will contract, and then it will expand and return to its
current size.
B. First it will expand, and then it will contract and return to its current
size.
C. First it will contract, and then it will expand and become much
larger than its current size.
D. First it will expand, and then it will contract and become much
smaller than its current size
Sun will contract, and then it will expand and become much larger than its current size. So, the correct option is (C).
What is Sun?The Sun is a type of star at the center of the Solar System, an almost perfect ball of hot plasma, heated to incandescence by nuclear fusion reactions in its core. The Sun radiates energy in the form of light, ultraviolet and infrared radiation, which is the most important source of energy for life on Earth.
In about 5 billion years the Sun will turn into a red giant. The core of the star will shrink but the outer layer will expand to the orbit of Mars, encircling the planet in the process.
Thus, Sun will contract, and then it will expand and become much larger than its current size. So, the correct option is (C).

during the polymerization of nucleic acids, covalent bonds are formed between neighboring nucleotides. which carbons are involved in such bonds?
During the polymerization of nucleic acids, covalent bonds are formed between neighboring nucleotides, and these bonds are called phosphodiester bonds. These bonds are formed between the phosphate group at the 5’ carbon of one nucleotide and the hydroxyl group at the 3’ carbon of another nucleotide.
Phosphodiester bonds connect the phosphate group to the 3'-OH group of adjacent nucleotides. These bonds are created by a dehydration reaction, which removes a molecule of water between the 3' hydroxyl of the terminal nucleotide and the phosphate on the incoming nucleotide. This reaction results in the formation of a phosphodiester bond, which involves the formation of a phosphodiester linkage between the 3’ hydroxyl of the preceding nucleotide and the 5’ phosphate group of the nucleotide being added.
Phosphodiester bonds create the backbone of the DNA double helix and are responsible for the stability of the nucleic acid molecules. DNA and RNA are made up of nucleotides that have a nitrogenous base, a pentose sugar, and a phosphate group, all of which are involved in the formation of the phosphodiester bond.

d. a starburst galaxy is a galaxy that is forming new stars at the centers of many dense clusters.
The correct definition of a starburst galaxy is: b. a starburst galaxy is a galaxy that is forming new stars at a very high rate.
When compared to either the galaxy's long-term average rate of star formation or the star formation rate seen in the majority of other galaxies, a starburst galaxy is one that is undergoing an extraordinarily high rate of star formation. The Milky Way galaxy, for instance, has star formation at a rate of about 3 million stars each year, whereas starburst galaxies can have star formation rates of up to one hundred million stars per year. The pace of star creation in a starburst galaxy is so high that it will completely deplete the gas reservoir from which the stars are born on a period substantially shorter than the galaxy's lifespan.

If a plant of a maple tree has more chloroplasts than the leaf of a tomato plant, then
Answer:
This question appears incomplete
Explanation:
This question appears incomplete. However, generally speaking, the higher the chloroplasts present in a plant, the higher the rate of photosynthesis that occurs in that plant. This is because chloroplasts are cellular organelles that serve as sites in which photosynthesis occur. They are found in green plants and green algae.
Photosynthesis is the process in which green plants produce there own food by absorbing sunlight from the atmosphere in the presence of carbon dioxide and water. Hence, it can also be said that an increase in the number of chloroplasts will lead to an increase in the amount of food produced by a plant (for itself).
From the description above, it can be said that the plant of a maple tree has a higher rate of photosynthesis and hence produced more food (for itself) than the leaf of a tomato plant.
Chloroplast also contain a green pigment called chlorophyll which is responsible for the green colour in green plants. Hence, an increase in the number of chloroplasts in a plant could indirectly imply greener plant. Hence, the plant of a maple tree could have greener leaf than the leaf of the tomato plant.
Notch is a receptor protein displayed on the surface of certain cells in developing fruit fly embryos. Notch’s ligand is a membrane-bound protein called Delta that is displayed on the surface of adjacent cells. When Notch is activated by its ligand, the intracellular tail of the Notch protein becomes separated from the rest of the protein. This allows the intracellular tail to move to the cell’s nucleus and alter the expression of specific genes.
Which of the following statements best explains Delta’s role in regulating cell communication through the Notch signaling pathway?
A. Delta transmits a chemical signal to all the cells of a developing embryo.
B. Delta allows the cells of a developing embryo to communicate without making direct contact.
C. Delta restricts cell communication to short distances within a developing embryo.
D. Delta determines which cells in a developing embryo express the gene that encodes the Notch protein.
If Delta is displayed on the surface of adjacent cells, and when Notch is activated by its ligand, the intracellular tail of the Notch protein becomes separated from the rest of the protein and allows the intracellular tail to move to the cell’s nucleus and alter the expression of specific genes, then C. Delta restricts cell communication to short distances within a developing embryo best explains Delta’s role in regulating cell communication through the Notch signaling pathway.

Explanation:
Mass extinctions were first identified by the obvious traces they left in the fossil record. In the strata corresponding to these time periods, the lower, older rock layer contains a great diversity of fossil life forms, while the younger layer immediately above is depauperate in comparison. Often, the rock layers bookending the mass extinction are noticeably different in their compositions. These changes in the rocks show the effects of environmental disturbation that triggered the mass extinction and sometimes hint at the catastrophic cause of the extinction.

c. mastication
d. ingestion
e. pharyngeal-esophageal phase of deglutition
After chewing food, you consciously decide to push the bolus to the back of your mouth into your pharynx with your tongue. The voluntary phase of swallowing, also known as buccal phase of deglutition.
Correct option is C.
This process is intentionally initiated by the person, and typically involves moving the bolus to the back of the mouth with the tongue and pushing it through the pharynx. The buccal phase of deglutition occurs before the involuntary phase, which is known as the pharyngeal-esophageal phase of deglutition.
During the buccal phase, facial muscles like the lips, cheeks, and nose help keep food in the mouth as the tongue and palate work together to help with shaping the food and pushing it back. Once at the back of the mouth, the bolus will be swallowed with a wave-like motion as it travels down the esophagus.

________ is the process by which nerve cells are coated with insulation that enhances the speed and efficiency of the information traveling through the nervous system.
The process by which nerve cells are coated with insulation that enhances the speed and efficiency of the information traveling through the nervous system is called myelination.
Myelin is a fatty substance that forms a sheath around nerve fibers, allowing electrical impulses to travel along the nerve cell more quickly and efficiently. Myelination starts in infancy and continues through childhood and adolescence, with different parts of the brain and nervous system myelinating at different rates.
Myelination is required for normal nervous system function, and disruptions in the process can result in a variety of neurological disorders.
Multiple sclerosis (MS), for example, is a disease in which the myelin sheath is damaged and the nervous system is unable to effectively transmit signals, resulting in a variety of symptoms such as weakness, numbness, and difficulty with coordination and balance.
