Can someone please help me I am doing a project were I have to wet a cloth and wrap it around a thermometer. Then I have a dry cloth and wrap it around another thermometer. The degrees for the wet one was 40 degrees and the dry one was 35. I had to do it three times and the dry one was still 35 on three trys and the wet one was still 40. now calculate the average. (f degrees - 32) x 5/9= the celsius

Answers

Answer:

Explanation:

35 + 35 + 35 + 40 + 40 + 40

(the numbers are there three times due to each trial value. you have to account for each.)

From the math you get 225.

Divide 225 by six due to their being six values

37.5 would be the average without the (f degrees-32) x 5/9

(now following the formula you put ((dont know if you have to follow though)))

37.5 - 32 x 5/9 = 3.055555556 degrees celcius.

BIOLOGY EXPERTS!!!! Shared core processes support the relatedness of all eukaryotes. Discuss how chromosome structure and function provides insights into the history of life on Earth.

Answers

Answer: Many eukaryotic organisms are related based on the shared core characteristics and processes.

Explanation:

The following are the shared core processes shared by all eukaryotes.:

1. Cytoskeleton: It is a network of structural proteins, that helps in movement of cell and organelle support.

2. Membrane-bound organelle: Mitochondria and chloroplast are organelles that formed via endosymbiosis these are present in all eukaryotic organisms.  

The DNA is the basic genetic material that is found in almost majority of living beings on earth. The DNA is being transmitted from the primitive organisms on earth to the modern day organisms. The chromosomes are the  carriers of DNA. These chromosomes are passed from the parents to the offsprings through reproduction. This is the basis of relatedness among organisms and these are also considered while studying the phylogenetic relationships.

How is glucose broken down in cellular respiration?

Answers

Answer: Glucose is broken down in the cytoplasm of the cell in a process called glycolysis. In stage two, the pyruvate molecules are transported into the mitochondria.

Explanation:

Glucose is broken down in cellular respiration into carbon dioxide and water.

What is cellular respiration?

Cellular respiration is a series of metabolic processes that take place inside cells to transform biochemical energy from meals into a substance known as adenosine triphosphate (ATP).

A glucose molecule gradually decomposes into carbon dioxide and water during cellular respiration. In the process of transforming glucose, some ATP is directly created. But far more ATP is later created through a procedure known as oxidative phosphorylation.

Glycolysis is the process by which glucose is metabolized in the cytoplasm of the cell. The pyruvate molecules are delivered to the mitochondria in stage two.

Therefore, during cellular respiration, glucose is converted to carbon dioxide and water.

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.

In the United States, the moon’s pull is strongest during which season?
1. spring
2. summer
3. fall
4. winter

Answers

Answer: Spring

Explanation:

Gravitational pull is affected by mass and distance. Since the moon’s mass does not change, the moon’s distance between Earth and the moon is the main consideration for the strength of lunar gravity. The moon’s pull on Earth waxes and wanes as the moon follows its elliptical orbit around the Earth, the distance between the two celestial objects increases and decreases. When they are nearest to each other, the moon is in the point of its orbit called the perigee, and its pull on Earth is the strongest.

On Earth, the moon’s gravity primarily is manifested as high and low tides, as the water bulges toward the moon. The effects of lunar gravity are felt the most at the constantly changing spot on Earth that is directly beneath the moon, called the sub-lunar point. At most times of the year, the moon has a greater pull on Earth than the sun does, but this changes during the times of year when the Earth’s orbit brings it closer to the sun. At these times, the sun’s gravitational pull causes spring tides, and when these coincide with the moon’s orbital perigee around the Earth, they are called perigean spring tides.

Earth exerts a gravitational pull on the moon 80 times stronger than the moon’s pull on the Earth. Over a very long time, the moon’s rotations created fiction with the Earth’s tugging back, until the moon’s orbit and rotational locked with Earth. This is called "tidal locking," and it explains why the same side of the moon always faces the Earth.

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.
