Answer:
DNA can store genetic information and most likely appeared before RNA.
Explanation:
Answer:
Vesicles that contained self-replicating RNA grew, split, and passed their RNA to daughters.
Explanation:
RNA played role in protein synthesis and also created its own catalyst.
How do both sodium and potassium ions travel
Answer:
Sodium ions pass through channels in the hydrophobic barrier that have been formed by membrane proteins. The crossing membrane is called facilitated diffusion because it is facilitated by the channel
Potassium ions have to be transocated through specific membrane transport proteins. It is then transported into the cell through potassium pumps with energy being consumed int the form of ATP.
The sodium-potassium pump goes through cycles of shape changes to help maintain a negative membrane potential. In each cycle, three sodium ions exit the cell, while two potassium ions enter the cell. These ions travel against the concentration gradient, so this process requires ATP.
Explanation:
Answer:
The sodium potassium pump goes through cycles of shape changes . In this way they help maintain a negative membrane potential. In each cycle, two potassium ions enter the cell while three sodium ions exit the cell . These ions travel against the concentration gradient. And this process requires ATP.

how do you living and nonliving things interact with each other? how might the function of an ecosystem be affected if living and nonliving things could not interact with each other?
Answer:
Some examples of living things are organisms such as plants, animals, fungi, and bacteria. Organisms interact with the living and nonliving things in their ecosystem to survive. ... These living things interact with the nonliving things around them such as sunlight, temperature, water, and soil
Which is evidence of climate-forced sea level rise?
A. decreased temperature of oceans
B. submerging of low islands and coastlines
C. temperature changes for surface currents
D. increased carbon dioxide in the atmosphere
In this exercise we have to use the knowledge of climate changes that demonstrate the increase in the sea level, in this way we have that:
The submerging of low islands and coastlines or letter B.
The rise in sea level caused by global warming could reach 2 meters in height by the end of the 21st century. This rise in the oceans would leave thousands of kilometers of coastline at the mercy of flooding, jeopardizing the safety of 745 million people worldwide.
What could happen with sea level rise?The recent rise in sea level is a result of global warming through two main processes: expansion of sea water due to warming of the oceans, triggering its thermal expansion, and the melting of ice masses.

Sickle-shaped red blood cells result from a mutation in the gene that codes for hemoglobin. This mutation results in sickle-cell anemia. A partial sequence of bases from a normal hemoglobin gene and a sequence that results in sickle-cell anemia are shown below
Complete question: Sickle-shaped red blood cells result from a mutation in the gene that codes for hemoglobin. This mutation results in sickle-cell anemia. A partial sequence of bases from a normal hemoglobin gene and a sequence that results in sickle-cell anemia are shown below (the diagram is in the attached file)
What type of mutation is depicted in this sequence?
Answer:
The type of mutation is known as SUBSTITUTION.
Explanation:
Sickle cell anaemia is an inherited disease caused by abnormal shape of the red blood cell. This abnormal red blood cell contains less haemoglobin and cannot transport oxygen efficiently round the body. Sickle-shaped (abnormal) red blood cells result from a MUTATION in the gene that codes for hemoglobin.
Mutation is the random changes in DNA that alters genetic information and so introduce new characteristics. The different categories of mutations include:
--> Chromosomal mutation and
--> Point mutation.
SUBSTITUTION is a type of point mutation in which one base is incorrectly added during replication and replaces the pair in the corresponding position on the complementary strand. From the diagram, a partial sequence of bases from a normal hemoglobin gene and a sequence that results in sickle-cell anemia, shows a substitution of an A for the middle T. This leads to GUA in the messenger RNA, which specifies the amino acid valine. The substitution of valine for glutamic acid at this particular position alters the chemistry of the hemoglobin such that it sticks together if it is not binding oxygen, creating sickling of the red blood cells.
Which of the following statements is not true of energy production in cells?
In cells, energy is released in small, controlled amounts
In cells, energy is released in small, controlled amounts
ATP is the primary form of energy for the cell.
ATP is the primary form of energy for the cell.
Cells release large amounts of energy in the form of heat.
Answer:
The third statement is not true.
Explanation:
Cells release small amount of chemical energy from glucose.
The correct answer is: "Cells release large amounts of energy in the form of heat."
Cells release energy by the process of cellular respiration.
A cell is the smallest unit of a living organism which can have independent existence.
Cells obtain energy by the process of cellular respiration. During cellular respiration, during cellular respiration, the energy stored in glucose is transferred to ATP.
The process of cellular respiration releases energy in cells in small controlled amounts.

How was life today similar and different to the Silurian period? ( animals, plants , organisms)
Answer:
The creatures developed in silurian period have evolved to live in sea bottoms.
Explanation:
Silurian life that is marine benthic which are bottom lying organisms belongs to the community of ecological zones that express themselves. As the gradients of temperature, pressure, and salinity. Consists of a community that is adapted to live in a darker region, used to lie in quieter environments that are in deep offshore water. These are much like the reef communities today as they do not tolerate excessive sediments. Prefer wave water that is shallow than 30 meters. These platforms are very gentle and are found over a hundred km gradients. Most of the fish represent the Silurian age and are widely distributed in marine environments. Examples of jawless fish, terrestrial fungi etc.Speciation means the formation of a new species.
True
False
Answer:
true
Explanation:
Definition: Speciation is the process by which new species form. It occurs when groups in a species become reproductively isolated and diverge.
Answer:
true because it means the formation of a new plant or animal species

The International Astronomical Union (IAU) defines a constellation by its:
boundary
star pattern
brightest star
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.

Is enzyme substrate complex concentration the product of enzyme concentration and substrate concentration?
Answer:
Yes
Explanation:
The enzyme substrate complex may be defined as the enzyme when interacting with the substrate at an active site and it produces a new product in the process. It is temporary molecule formed when the substrate comes in contact with the enzyme.
An enzyme is the molecule of a protein which acts like an organic catalyst and a substrate is a the molecule which interacts with the specific enzyme to form a product.
Therefore, the enzyme substrate complex concentration is the product of the substrate concentration as well as the enzyme concentration.
