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 )

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.

Why is an overabundance of nutrients harmful to a water supply?
A.
It decreases the number and types of aquatic plants.
B.
It kills all aquatic plants.
C.
It sterilizes water.
D.
It causes excessive aquatic plant growth.

Answers

Answer:

d

Explanation:

It leads to a process called as eutrophication in which the aquatic plants grow regularly over the water surface and the living beings living inside the water gets diminished because of the lack of nutrients and the various substances required for the growth.

What is water sterilization ?

It is the process in which the harmful substances and contaminants are removed outside the water source such that the water can be removed out from water resources such that they can be made appropriate for drinking.

An overabundance of various nutrient primarily nitrogen along with phosphorus in water begins a process known as eutrophication. The process hammers the growth of other lives present on the sources.

Algae feed on nutrients, growing, spreading  and turning out the water green. Algae blooms smells bad, blocks sunlight and even releases out  chemicals in certain cases.

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

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.)

Based on the pedigree that is shown above, how to describe Fred?

Answers

Answer:

The given pedigree analysis shows sex-linked trait where the female work as a carrier and have X linked recessive gene that is [tex]X^{h}[/tex] and the male is normal.

So, Fred will be a male with [tex]X^{h}[/tex][tex]Y[/tex] gene and Fred will be affected with X linked disease which is carried by female.

If,  [tex]X^{h}[/tex] gene in the female (Ann)  act as a carrier of hemophilia and the male (John) is normal, then Fred will be a male affected with hemophilia (sex linked disease).

Hence, Fred will be affected male with  [tex]X^{h}[/tex][tex]Y[/tex] genotype.

Which of the following is the correct equation for photosynthesis?
a.) CO2 + light + H2O --> O2 + Sugar
b.) CO2 + sugar + H2O --> O2 + light
c.) O2 + light + H2O --> CO2 + Sugar
d.) CO2 + O2 + H2O --> Light+ Sugar

Answers

Answer: a

Explanation: light is a energy sourse for the photosintesis and sugar is glucose  wich is the food formd at the end of phothosintesis like oxigen..(etc..)....

The answer option with the correct equation for photosynthesis is: A. [tex]CO_2 + light + H_2O --> O_2 + Sugar[/tex]

Photosynthesis can be defined as a biological and chemical process through which living organisms such as green plants (autotrophs), transform light energy (sunlight) into chemical energy.

The correct equation for photosynthesis is given by this chemical equation:

                       [tex]CO_2 + light + H_2O --> O_2 + Sugar[/tex]

Hence, the necessary input for the process of photosynthesis to take place include the following:

Water ([tex]H_2O[/tex]).Sunlight (light energy).Carbon dioxide ([tex]CO_2[/tex]).

In conclusion, oxygen and sugar are end products (output) of photosynthesis rather being an input.
