the interphase is the stage in which the cell duplicates its content. Mitosis is the stage in which the cell divides into two new cells.
What is the interphase?The interphase is the stage before cell division occurs. During the interphase, the cell prepares to divide into two new daughter cells (mitosis).
The interphase is composed of three phases,
The G1 stage ⇒ the cell duplicates in size. The organelles and other cytoplasmatic structures duplicate. The S stage ⇒ occurs the DNI replication process, the synthesis of histones and other associated proteins.The G2 stage ⇒ begins the slow process of DNI condensation. Duplication of centrioles completes. Structures such as spindle fibers are assembled.What is mitosis?Mitosis is a process by which, from a diploid somatic cell (2n), two daughter diploid cells (2n) are produced.
Mitosis occurs in only one phase,
In the prophase, it occurs chromosomes condensation and nuclear membrane breaks.During the metaphase, chromosomes are taken toward the center of the cell by the spindle apparatus. Once in the equatorial plane, chromosomes line up.Each chromatid joins with a microtubule of opposites poles.
In Anaphase, chromatid sisters separate. The bonds that were keeping them together break, and each of them migrate to the opposite poles.In telophase, duplicated chromosomes are already in the corresponding poles, and the nuclear membrane forms again in each pole. Finally, cytokinesis occurs.In conclusion, the interphase is the stage in which the cell duplicates its content. Mitosis is the stage in which the cell divides into two new cells.

Review of the scientific method: Sea turtles navigate the world’s oceans by using magnetic fields. The state of Georgia has asked you to determine if the installation of a large wave-powered electricity generator (that produces an alteration in magnetic fields) will affect sea turtles. Given what you know, you suspect that the new electric station will not affect sea turtle navigation. You collect the same species of sea turtles, all about the same age, from one beach and divide them into two groups. The first group is taken 3 miles away and released. The second group is taken 3 miles away and released near a strong magnet. You track how long it takes for the turtles to return to their starting location. Identify the following parts of the experiment.

Students testing the effects of solute concentration in soil on plant transpiration noticed a significant decrease in transpiration when abscisic acid was used as the solute. Even at molar concentrations less than 0.2 M, transpiration seemed to stop almost completely.
a) Make a claim as to which structural and/or physiological component of transpiration is affected by the presence of abscisic acid.
b) Explain the reasoning that supports your claim.
Answer:
look in textbook - concept 29.6
Explanation:
Drought stress can also cause stomata to close. A hormone called abscisic acid (ABA) is produced in roots and leaves in response to water deficiency and signals guard cells to close stomata. This response reduces wilting but also restricts CO2 absorption, thereby slowing photosynthesis. ABA also directly inhibits photosynthesis. Water availability is so tied to plant productivity not because water is needed as a substrate in photosynthesis but because freely available water allows plants to keep stomata open and take up more CO2.
abscisic acid (ABA): A plant hormone that slows growth, often antagonizing the actions of growth hormones. Two of its many effects are to promote seed dormancy and facilitate drought tolerance.
The plant hormone abscisic acid (ABA) is naturally produced in response to drought situations and reduces transpiration (E) by remaining in the stomata. for that reason, ABA can also lengthen shelf lifestyles of retail vegetation by reducing water loss.
How does abscisic acid affect the outlet and remaining of the stomata?Abscisic acid (ABA) is a plant hormone involved in the response of flora to decreased water availability. Discount of guard cell turgor via ABA diminishes the aperture of the stomatal pore and thereby contributes to the capability of the plant to conserve water in the course of intervals of drought.

(c) Many bacterial diseases can no longer be treated with antibiotics. Outline how
antibiotic-resistant strains of bacteria can develop.
Antibiotics kill or inhibit the growth of susceptible bacteria. Sometimes one of the bacteria survives because it has the ability to neutralize or escape the effect of the antibiotic; that one bacterium can then multiply and replace all the bacteria that were killed off. Exposure to antibiotics therefore provides selective pressure, which makes the surviving bacteria more likely to be resistant.

It is a yearly measurement of light given off by stars.
It is the amount of time it takes light to travel one million kilometers.
The statement accurately describes a light-year is it is the distance that light travels in a year. Therefore, option (B) is correct.
What do you mean by light year?A light-year, also spelled light year, is a significant length measure that is used to express astronomical distances. It is around 9.46 trillion kilometers, or 5.88 trillion miles, in length.
The distance that light travels in a light-year is one year. At 186,000 miles (300,000 kilometers) per second and 5.88 trillion miles (9.46 trillion kilometers) per year, light travels through interstellar space.
The distance that light travels in a year is called a light year (365 days). Because "year" is right there in the name, it is frequently used incorrectly as a measure of time.

which cell organelles are known as secretary vesicles
Answer:
the membrane
Explanation:
Secretory vesicles are tiny little packages in which certain cell secretions can be transported. The vesicles are membrane bound and produced by the golgi apparatus or endoplasmic reticulum. Most vesicles will have specialized functions and specific materials which they transport. In addition to transportation, secretory vesicles can store or digest certain secreted molecules. Synaptic vesicles store neurotransmitters, hormones are stored in secretory vesicles for release into the blood stream, and enzymes are also stored in secretory vesicles to be used when needed to make cell walls in certain plants, fungi, and bacteria. The release of the substances inside of the secretory vesicle can be stimulated by a neural or hormonal signal. The membrane of the vesicle can then fuse with the membrane of the target cell and essentially spill its contents. The vesicle then adds its membrane to that of the target cell. This is typically temporary until another vesicle is created when certain components are then removed from the cell.

Have you ever sat around a campfire or watched flames flicker in a fireplace? The burning of wood is a chemical reaction. A chemical reaction always involves changes in chemical bonds that join atoms in compounds. The elements or compounds that enter into a chemical reaction are called reactants. The elements or molecules produced by a chemical reaction are called products. As wood burns, molecules of cellulose are broken down and combine with oxygen to form carbon dioxide and water vapor, and energy is released. What are the reactants when wood burns? What are the products when wood burns?
Answer:
The correct answer is -
Reactants - oxygen and cellulose.
Products - carbon dioxide and water (carbon residues sometimes)
Explanation:
Burning wood is a chemical reaction that involves a reaction between reactants and produces products with energy. In this chemical reaction, the reactants that take part are oxygen present in the atmosphere and cellulose (wood made up of cellulose).
In this reaction a lot of energy or heat loss takes place and at the end of the reaction carbon dioxide and water produces. however, sometimes other substances also present.
