List as many examples of types of proteins, and give a brief definition of each
1. Structural proteins, maintain cell shape, akin to a skeleton, and compose structural parts of the body, like cartilage and bone in vertebrates.
2. Storage proteins house critical elements that your body needs.
3. Hormonal proteins basically act as your body's chemical "messengers."
4. Enzymes, which are biological catalysts needed for chemical reactions.
How does the tRNA-mRNA interaction ensure that the amino acids are added in the correct order?
Answer:
Only the tRNA carrying the next amino acid in the polypeptide chain has the anticodon that binds to the appropriate location on the mRNA.
This system ensures that amino acids are added to the chain in the correct order. At the beginning of translation, the ribosome and a tRNA attach to the mRNA.

B. atoms are rearranged in materials
Explanation:
Why are phase changes considered physical and not chemical
changes?
Answer:
Phase changes are physical changes that take place when matter changes energy states, but chemical bonds are not broken or formed. ... The phase of a substance depends on the amount of energy the atoms contain. All atoms are in motion. The higher the temperature of an atom, the faster the motion

A solar eclipse occurs when a portion of the Earth is engulfed in a shadow cast by the Moon which fully or partially blocks sunlight. This occurs when the Sun, Moon and Earth are aligned. Such alignment coincides with a new moon indicating the Moon is closest to the ecliptic plane.
Answer:
A
Explanation:
To see a total eclipse, where the moon fully covers the sun for a short few minutes, you must be in the path of totality. The path of totality is a relatively thin ribbon, around 70 miles wide, that will cross the U.S. from West to East.

An animal is then able to walk or run because the muscles of the muscular system work with the bones of the skeletal system. The musculoskeletal system is what enables movement.
What is skeletal system?The skeletal system of the body has been composed of the bones and cartilage and they will perform many different types of function in the body of the organism. The cartilages along with the bones form the structural framework of the body. It also helps in the performing locomotory functions of the body. The brain signals the body of an animal to move by transmitting electrical impulses through the neurons.
It has the skeletal system of the body that helps in the walking, bending, sitting and as well as other movements of he body. It has been also serves as the barrier between the outer environment and internal organs and protects them from any exertion and shock.
Therefore, An animal is then able to walk or run because the muscles of the muscular system work with the bones of the skeletal system. The musculoskeletal system is what enables movement.

When do you see a partial lunar eclipse?
O A
when the Moon passes through the Earth's penumbral shadow
OB. when the Moon lies exclusively in the Earth's penumbral shadow
Ос.
when a portion of the Moon passes through the Earth's umbral shadow
OD.
when the Moon lies exclusively in the Earth's umbral shadow
Answer:
C. when a portion of the moon passes through the earth's umbral shadow.
Explanation:
A partial lunar eclipse occurs when the Earth passes between the sun and moon but the celestial bodies are not arranged in a straight line. When that occurs, a small part of the moon's surface is covered by the darkest, central part of the shadow of the Earth called the umbra. The rest is covered by the outer part of the shadow, termed penumbra.

Doctors found out that you are suffering from a serious disease that can only be cured using stem cell therapy. The doctors explain that both adult and embryonic stem cells can be used in your case. Which of the 2 types would you prefer and why? Use facts about each to support your answer.
Answer:
embryonic stem cells
Explanation:
I prefer embryonic stem cells instead of adult stem cells because embryonic stem cells can be differentiate into any cell type whereas adult stem cells can't be differentiated into other cell type. Due to this feature of embryonic stem cells, it can be used for the therapy and the disease can be cured with the help of these embryonic stem cells. So I prefer embryonic stem cells due to their unique ability of differentiation into any type of cell.

there are 12% cytosines in a DNA molecule , what percentage of thymines
Answer:
To calculate the percentage of thymine we need to use Chargaff's rule:
Chargaff's rules state that the amount of guanine should be equal to cytosine and the amount of adenine should be equal to thymine
A+G=T+C
A=T
C=G
100%-(2x12)=2T
T=(100%-24%)/2
T=38%

After filling out the information above, answer this question in depth (at least 5 sentences). Use your notes as necessary. Why may chromosomal disorders be more detrimental than DNA mutations?
Answer: Chromosomal disorders are the disorders that are caused due to the presence of extra chromosomes, or absence of one or more chromosomes or specific part of the chromosomes. Mutation can be defined as the change that occurs in the genetic makeup of the organism either during copy of genome during replication or due to external factors like exposure to ultraviolet radiations, cigarette smoke, and due to carcinogenic agents.
Explanation:
The change in shape of the chromosome as compared to the normal one also exert influence over the functions. Down syndrome, Klinefelter syndrome, Turner syndrome, and others are the examples of the chromosomal disorders. These syndromes affect the normal functioning of the human being rendering it unfertile, rudimentary development of sex organs, development of traits in opposite sex, induce short life span, poor health, lack of proper mental development, and other abnormal characteristics in the effected individuals. On the other hand mutations are not always detrimental, only a small percentage of mutations can cause genetic disorders. Some mutations can change the genetic makeup by does not affect the functioning of the protein thus the physiological functions of the body are remained restored.

The International Astronomical Union (IAU) defines a constellation by its:
boundary

Greek name
Answer:
Each constellation is a region of the sky, bordered by arcs of right ascension and declination. ... Together they cover the entire celestial sphere, with their boundaries adopted officially by the International Astronomical Union in 1928 and published in 1930.
So I would say its A : Boundary
Explanation:
- Eijiro <3
Love the pfp by the way! :D
The International Astronomical Union (IAU) defines a constellation by its boundary. The correct option is A.
What is International Astronomical Union?In 1919, the International Astronomical Union (IAU) was established. Its goal is to encourage and protect astronomy in all of its forms, including research, interaction, education, and development, through international cooperation.
The International Astronomical Union (IAU) is the oldest intergovernmental organization of professional astronomers, having been in existence for over a century. It has over 13000 members and 82 national members, among them India.
The IAU designates a constellation by its boundary rather than its pattern, and the same constellation can have multiple representations. Asterisms should be distinguished from constellations.
Thus, the correct option is A.
