Who were the earliest Astronomers

Answers

Answer 1

Answer:

The Ancient Greeks developed astronomy, which they treated as a branch of mathematics, to a highly sophisticated level. The first geometrical, three-dimensional models to explain the apparent motion of the planets were developed in the 4th century BC by Eudoxus of Cnidus and Callippus of Cyzicus.

What are possible products of glycolytic, or anaerobic, catabolism?

Answers

Answer:

The products of a glycolytic metabolism is lactic acid and the increase of the insulin enzyme at the plasma level.

Explanation:

Lactic acid is the product of the reaction of glucose catalysis in oxygen-deficient states such as in anaerobic activity.

Lactic acid is an acid that can be metabolized by the body, which accumulates in the muscles, and is generated once the physical activity has finished or in the last stages.

Insulin, once generating the rest of the activity, or the cessation of the action, comes into play at the plasma level and increases, in order to neoform new energy reserves (glucose) and thus prepare for the next action.

This hormone has the opposite effect to glucagon.

it is an independent variable as it can be changed by studying and also a dependent variable as you can measure her results and see its increase or decrease

Explanation:

hope this helps

could u pls help me with my latest questions pls pls pls pls pls

The variables in the given situation would be as follows:

A). Independent Variable: Amount of time given on study

B). Dependent Variable: Grade in Science

C). Control: Additional Study of 30 minutes

In an experiment or research, an independent variable is described as a variable that remains unaffected by the change in other but rather a manipulation or change in it can affect the other variables. Dependent variables are the variables that receive a direct effect of change in the other variable and therefore, it is the variable that the researcher aims to measure or study.While control helps in making the comparison of the results with or without it. Thus, the given variables are classified in this situation as mentioned above.

Mitochondria differ from chloroplasts in that Group of answer choices mitochondria convert solar energy to chemical energy whereas chloroplasts convert one form of chemical energy to another mitochondria contain three different membrane-bound compartments, whereas chloroplasts contain two mitochondria contain membrane folds called cristae, whereas chloroplasts contain vesicles in stacks called grana mitochondria are not found in plants, whereas chloroplasts are not found in animals

Answers

Answer:

mitochondria contain membrane folds called cristae, whereas chloroplasts contain vesicles in stacks called grana  

Explanation:

Mitochondria are composed of two membranes (i.e., the inner and outer membranes), which are separated by the intermembrane space. The inner mitochondrial membrane is composed of several folds that form the cristae, which extend into the mitochondrial matrix. On the other hand, in chloroplasts, the inner membrane consists of interconnected stacks of sacs named thylakoids, whose arrangement is known as grana.

In the thylakoid membranes, what is the main role of the antenna pigment molecules?
a) split water and release oxygen to the reaction-center chlorophyll
b) harvest photons and transfer light energy to the reaction-center chlorophyll
c) synthesize ATP from ADP and Pi
d) concentrate photons within the stroma

Answers

Answer: Option B.

harvest photons and transfer light energy to the reaction-center chlorophyll

Explanation:

In the thylakoid membranes,the main role of the antenna pigment molecules is harvest photons and transfer light energy to the reaction-center chlorophyll because the photon of light move until it get to a molecule in the chlorophyll. When it reaches the molecule, it causes an excitation of electrons in the chlorophyll. The energy then present allow it to break free from the chlorophyll atom, which indicate chlorophyll donating an electron and the energy that is absorbed is then converted to heat.

Think of white blood cells as your immunity cells. In a sense, they are always at war. They flow through your bloodstream to fight viruses, bacteria, and other foreign invaders that threaten your health. When your body is in distress and a particular area is under attack, white blood cells rush in to help destroy the harmful substance and prevent illness.

Which of the following statements concerning ribosomes is true?
A. Several ribosomes are often attached to and translating the same MRNA.
B. Ribosomes join amino acids together to form a polypeptide.
C. Ribosomes have one binding site for MRNA and three binding sites for 1RNA molecules.
D. Ribosomes are the organelles responsible for protein synthesis.
E. All of the above statements are true.

Answers

Answer:

E. All of the above statements are

Explanation:

Ribosomes are organelles found free floating in the cytoplasm or attached to endoplasmic reticulum (RER). They are the site of protein synthesis in a cell. Ribosomes initiate the translation process by binding to the mRNA molecule using their mRNA binding site. Several ribosomes called POLYSOMES are often attached to and translating the same MRNA molecule.

A ribosome contains four (4) binding sites; one for the mRNA and three (P-site, A-site and E-site) for tRNA, which are small RNA molecules that carry and add amino acid to the growing polypeptide chain during the process. In a nutshell, the ribosome via the aid of tRNA is responsible for joining amino acids together to form a polypeptide chain (future protein).

Ribosomes are complicated macro molecules composed up of nucleic acids and proteins. They are important as they perform a major role in protein assembly and transportation.

The correct answer is:

Option E. All of the above statements is true.

The explanation for the above option is:

The ribosome is located either free or is connected to the endoplasmic reticulum(RER).

Ribosomes assist in the translation of the information from mRNA.

Polysomes are numerous ribosomes connected to a single mRNA molecule.

Ribosomes have one binding position for mRNA and three binding positions for tRNA molecules.

The three binding sites for tRNA is (A- site) amino acyl site, (P-site) peptidyl site and (E site) the exit site.

Ribosome assembles amino acids to form a polypeptide chain. These polypeptides get transported to the cytoplasm.

Therefore all the above statements are true for ribosomes.

Answers

Answer:

DNA unzips between base pairs.

Explanation:

This is the first step of protein synthesis.

The first step of protein synthesis is attachment of mRNA to ribosomes. Option A is correct.

Protein synthesis:

It is known as translation. In this mRNA is translated in to the sequence of amino acids which ultimately form protein.

First mRNA attach to ribosome,tRNA bring amino acid to ribosomes and attach to mRNA.Amino acids bond together via peptide bond.

Therefore, the first step of protein synthesis is attachment of mRNA to ribosomes.

Water has the property of having a high specific heat. This trait has a great influence on maintaining homeostasis within the body. Which of the following accurately explains what it means to have a high specific heat

Answers

Answer:

We can write the specific heat as:

C = (dU/dT)

Where C is the specific heat, U is the internal energy and T is the temperature.

This is:

"How much does change the internal energy when the temperature changes".

Having a high specific heat (and positive) means that for every little increase in the temperature we will have a large change in the internal energy.

What does this mean?

Think in the inverse way:

A larger specific heat means that we need a large amount of heat (the heat is energy) to change a little the temperature.

Then this is good, because even when receiving a lot of heat, the body temperature will remain about the same.

Which clue can be used to identify a chemical reaction as a combustion reaction? Oxygen is a product. A hydrocarbon reacts with oxygen. Water and carbon dioxide react. The reaction involves ions.

Answers

Answer:

A hydrocarbon reacts with oxygen

Explanation:

The clue that can be used to identify a chemical reaction as a combustion reaction from the options would be if a hydrocarbon reacts with oxygen.

Basically, a combustion reaction is a kind of reaction involving oxygen and another reactant with energy being released in the process. The energy is usually in the form of light and heat.

Thus, following the definition:

Oxygen is rather a reactant, and may not be a product in combustion reactionsWater reacting with carbon dioxide is not a combustion reactionReaction involving ions may not be a combustion reaction

The only reaction that may identify as a combustion reaction is, therefore, the one involving hydrocarbon and oxygen.
