During mitosis, chromatin condenses into chromosomes, spindle fibers form from one end of the cell to the other, and centrioles organize the spindle fibers. Which stage of mitosis happens next?
Answers
Answer:
Metaphase
Explanation:
Mitosis is the cell division that involves the production of daughter cells that are genetically identical to the parent cell. Mitosis is undergone by every living cell and it includes four main stages: Prophase Metaphase, Anaphase, and Telophase.
The description in this question showcases the Prophase stage, which is the first stage of mitosis. The Prophase stage involves the condensation of Chromatin threads into Chromosomes. The mitotic spindle, which contains the microtubules that will separate sister chromatids begins to form. The next phase involves the aligning of chromosomes at the cell's equator, which occurs in the METAPHASE stage.

Metaphase

Jane has a beaker containing a clear solution. She adds a liquid pH indicator to the clear solution and observes that the solution changes to bright blue. The clear solution in the beaker must be a(an)
Answers
Answer: a (weak) acid
Explanation: the solutions are mostly neutral but the pH shown by the indicator as a bright blue means it is slightly acidic meaning the pH is between 6 and 7.6
As the solution turns bright blue on addition of indicator, the solution in beaker must be a weak base.
What is a base?
According to the Arrhenius concept, base is defined as a substance which yields hydroxyl ions on dissociation.These ions react with the hydrogen ions of acids to produce salt in an acid-base reaction.
Bases have a pH higher than seven as they yield hydroxyl ions on dissociation.They are soapy in touch and have a bitter taste.According to the Lowry-Bronsted concept, base is defined as a substance which accepts protons .Base react violently with acids to produce salts .Aqueous solutions of bases can be used to conduct electricity .They can also be used as indicators in acid-base titrations.
They are used in the manufacture of soaps,paper, bleaching powder.Calcium hydroxide ,a base is used to clean sulfur dioxide gas while magnesium hydroxide can be used as an antacid to cure acidity.

B. Scientists repeat the experiments to verify results and reevaluate

Explanation:
This is kind of process of elimination. Scientists don't move onto new ideas with out proof so C it out. They wouldn't just ignore new data so it's not D. Between A and B, B seems most likely because when scientists look into new data they wouldn't necessarily have the mindset of trying to prove that it is unreliable. They just want to confirm and learn.

If microwave radiation in the universe were visible, it would be bright and
astonishingly uniform. How does this support the Big Bang theory?
Answers
Answer:
Well, background radiation is used to determine how the universe was made, in this case, The Big Bang, if microwaves were visible, astronomers would be able to determine the age. Microwaves would be between orange-red, it might get brighter.
Explanation:
Hope this helps.
The bright and astonishingly uniform color of microwave radiation would : make background radiation visible to astronomers studying the age of the universe ( using the Big bang theory )
The Big bang theory is a cosmological model that proposes that the new universe was formed from the expansion of a Larger body having a high level of density and temperature.
The background radiation is a microwave radiation that is studied by astronomers to determine the age of the universe, therefore if microwave radiation has a bright color it will help the astronomers determine the age of the universe easily and also proving that the formation of the universe was from the Big bang.
Hence we can conclude that The bright and astonishingly uniform color of microwave radiation would : make background radiation visible to astronomers studying the age of the universe ( Big bang theory )

Why xylem and phloem are called complex tissues? How are they different from one another?
Answers
Answer:
Xylem and phloem are called complex tissues because they are made up of more than one type of cell working together as a unit. The xylem transports H2O and minerals upward from the roots to the leaves, and is composed of tracheid cells which are dead at maturity (no active nucleus, makes the tree stem hard). If plants don't have xylem, they will stay lower to the ground as it is responsible for making the tree grow upward. The ends of the xylem tubes are tapered (pointed), materials are passed along one cell at a time, and the tubes are narrow and continuous. The phloem transports sugars and proteins downward from the leaves to the stems and storage roots. The cells that make up the phloem are called sieve tubules and companion cells. The companion cells have the nucleus and the sieve tubules contain the cytoplasm.
Explanation:
My teacher helped us remember using the phrase "phloem down the river" because it sounds like 'flowing down the river' (to help remember that phloem transports downward and xylem transports upward.)

Which question would be asked in a dichotomous key?
A. How long are the insect's antennae?
B. Are the insect's antennae longer than its head?
C. Are the insect's antennae long or short?
D. How does the insect use its antennae?
Answers
Answer:
B. Are the insect’s antennae longer than its head?
Explanation:
Dichotomous key refers to the tool or method which helps the scientist to identify organisms.
It uses a specific series of questions which help in segregation of organisms and ultimately help the scientist to identify the organism on the basis of the observations or properties share by the organism.
Example of a simple dichotomous key is shown below.
Similarly, insects can have antennae longer or shorter than their heads. Thus, the question "Are the insect’s antennae longer than its head?" would help in segregating insects based on their antennae length.
happy to help ya:)
The statement B is correct. Are the insect’s antennae longer than its head?
What do you mean by dichotomous keys?A dichotomous key is an important scientific tool, used to identify different organisms, based the organism's observable traits. Dichotomous keys consist of a series of statements with two choices in each step that will lead users to the correct identification.
Moreover, for example, in tree identification, a dichotomous key might ask whether the tree has leaves or needles. The key then directs the user down one list of questions if the tree has leaves, and a different question list if it has needles.
Therefore, dichotomous keys are useful for biological classification as well as identification. The word dichotomous is derived from the Greek words meaning “two parts.” Each step in the key provides two contrasting choices about a characteristic.
