Help asap !!!! Which of these statements is true of the brightest stars? (1 point)
O They are yellow stars.
O Many are supergiants
O Several are white dwarfs.
O Each is part of the main sequence.
Answer:
Many are supergiants.
Explanation:
A star's size and core temperature determine its brightness. The brightest stars tend to be blue or blue white. Supergiants and red giants are in the region above the main sequence of stars, so that isn't true. Red are the dimmest. Yellow stars are in the middle of that spectrum. White Dwarfs are dimmer than the Sun, red giants and blue supergiants.

What is the 11 year solar cycle?
The Sun's magnetic field goes through a cycle, called the solar cycle. Every 11 years or so, the Sun's magnetic field completely flips. This means that the Sun's north and south poles switch places. Then it takes about another 11 years for the Sun's north and south poles to flip back again.

Explanation:
DNA and RNA are ______ that serve as templates that form proteins
Answer:
In the first step, the information in DNA is
transferred to a messenger RNA (mRNA)
molecule by way of a process called
transcription.... The mRNA sequence is
thus used as a template to assemble-in
order-the chain of amino acids that form a
protein.
A type of RNA that is called as ribonucleic acid type called as transfer RNA that is used for the production of the amino acid at a time and the protein assembly takes place at the ribosomes.
What is the role of DNA and RNA for the sake of protein synthesis ?
DNA are responsible for the providing out the code for the cell's activities and the RNA are responsible for providing out the service to make them proteins.
Each group of 3 bases in the mRNA constitutes a codon and each codon is specifying a particular type of amino acid. The mRNA sequence therefore used as a template to make the assembly in order of the chain of amino acids which form a protein.
It is found that in all biological cells , usually occurs in cytoplasm of cell though its production takes place in nucleus. Whereas DNA is providing the code for cell's activities and RNA is responsible for converting that code into proteins which carry various cellular functions.

a signal molecule which can bind to an enzyme and shut down its activity by altering the shape of the enzyme.
Answer:
Enzyme inhibitor
Explanation:
An enzyme inhibitor is a molecule that binds to an enzyme and decreases its activity. By binding to enzymes' active sites, inhibitors reduce the compatibility of substrate and enzyme and this leads to the inhibition of Enzyme-Substrate complexes' formation, preventing the catalysis of reactions and decreasing the amount of product produced by a reaction.

How do we know that the ocean is continually absorbing carbon from the atmosphere, helping with climate stability?
O Increased carbon in the oceans have made them more acidic.
O Ocean pH has increased significantly in the last decade.
O There are bubbles like carbonation on the ocean surface.
O Fish we catch and eat from the ocean are made of carbon.
The concentration of carbon is increased in the oceans have made them more acidic.
Increased carbon concentration in the oceans which have made the ocean water more acidic is the indication that more carbon is absorbed by the ocean. When carbon absorbed by the ocean, the carbon reacts with water which produced carbonic acid.
This carbonic acid decrease the pH of the ocean water that adversely affect the marine organisms especially coral reefs. When the pH of the ocean water increases, bleaching of coral reef occurs because the algae living on them die so we can conclude that the concentration of carbon is increased in the oceans have made them more acidic.

Construct a Venn diagram that compares and contrasts sexual and asexual reproduction.
Include the following phrases:
haploid (n)
diploid (2n)
gamete
somatic
mitosis
meiosis
cell division
chromosomes separate
genetically identical
genetically different
The Venn diagram makes a comparison between categories. Intersection: Cell division/Asexual: diploid, somatic, mitosis, genetically identica/Sexual: haploid, gamete, meiosis, chromosomes separate , genetically different.
------------
A Venn Diagram is represented as two or more circles with some degree of superposition between them. It is used to make comparisons expressing similitudes and differences between things.
Each circle represents a category -in this example, sexual and asexual reproduction-.
The superposed area is named intersection and shows things in common between the two categories.
We already know that sexual reproduction occurs by the process of meiosis, while asexual reproduction occurs by mitosis.
In superior organisms, there are two types of cells: Somatic cells and germ cells.
The somatic cells are diploid (2n), meaning that each cell has a pair of equal chromosomes. The somatic cells are all the body cells except for the sexual ones, and they reproduce by the process of mitosis.
In somatic cells, one of the sets of chromosomes is inherited from the maternal side, while the other homologous set of chromosomes is inherited from the paternal side. Hence, the number of chromosomes in these double sets of the somatic cells is diploid, 2n.
Mitosis is a process through which, from a diploid somatic cell (2n), two identical daughter diploid cells (2n) are produced.
First, occurs duplication of the cell content, and then the separation into two new cells happens.
Germ cells suffer mitosis and meiosis.
Through meiosis, germ cells produce gametes, called sperm and egg cells, through the gametogenesis process.
Gametes are haploid (n) with half the number of chromosomes that might be found in the somatic cells.
During gamete formation, the pairs of homologous chromosomes separate after crossing over. Then, sister chromatids also separate. The result is the formation of four gametes.
Each gamete has different information from the combination of homologous chromosomes belonging to the father and to the mother.
Gametes' destiny is to merge in the process of fecundation, during which a new diploid cell called zygote emerges through fertilization.
The zygote is a complete cell that suffers successive mitosis to form the new organism.

What is the name given to the process by which a parent cell becomes two identical daughter cells?(1 point)
A. meiosis
B. differentiation
C. senescence
D. mitosis
Answer:
D. mitosis
Explanation:
Mitosis is the process whereby the parent cell divides into two daughter cells that are identical.
Mitosis is the process by which a parent cell becomes two identical daughter cells. So, the correct option is (D)
What is mitosis ?Mitosis is the process in which cell duplication, or reproduction takes place. Wherein one parent cell gives rise to two genetically identical daughter cells. Mitosis is the duplication and distribution of chromosomes which carries the genetic information.
It is an important process in single celled eukaryotes as it is the mode of asexual reproduction. The main function of Mitosis is to produce more cells.
Life starts with single cell in multicellular organism which is formed from two gametes. Mitosis takes place one cell is divided into two cells as this single celled multicellular organism only carries genetic information in the form of DNA but not enough cells. These two cells further divide mitotically into four cells, then into 8 , then 16 and then 32.
It is essential to life because it give rise to new cells for growth and replacement of dead cells. It may take few minutes or some hours, depending on the type of cells. It depends on time, temperature and chemicals.
Thus, mitosis is the process by which a parent cell becomes two identical daughter cells. So, the correct option is (D).
