Activity
In this activity, you will research the genetic diversity in two fish variants. The Mexican tetra (Astyanax mexicanus) has two notable variations: the surface variety and the blind cave fish variety. In this activity, you’ll use credible websites to find the following information about these two fish:

What type of habitat does each fish live in?
How do their physical characteristics differ?
How are they similar?
Can the two types mate with each other?
Why are their characteristics advantageous to their environments?
When you’ve found the information, answer the following questions.

Part A
What are the similarities and differences between the two fish varieties?

Answers

Answer 1

Answer:

The surface fish lives near the surface of the water, but the blind fish live in caves.

Explanation: yes

Answer 2

Answer:

The surface fish live near the surface of the water, and the blind cave fish live in dark subterranean caves. The surface fish have eyes and pigmentation on their bodies. The blind cave fish don’t have eyes, and they’re often albinos.

Answers

Answer:

Weight of the soil (500g)

Explanation:

According to this question, some students are conducting an experiment in order to find out which of the different soils used absorb heat the fastest. For the first test, they put 500 grams of SAND in a beaker and put a thermometer in the sand.

In an experiment, the variables that must be kept constant for all the groups is called the CONSTANT OR CONTROLLED VARIABLE. This is done in order not to influence the outcome of the experiment. In this case, the weight (500g) of the soil should be kept the same for all other tests.

This means that for the remaining soil being tested, 500g of each type of soil should be used.

Answers

Answer:

D. Krebs Cycle

Explanation:

Hope this helped.

The answer to this question is Krebs Cycle.  

Krebs cycle. A series of chemical reactions that occur in most aerobic organisms and are part of the process of aerobic cell metabolism, by which glucose and other molecules are broken down in the presence of oxygen into carbon dioxide and water to release chemical energy in the form of ATP.

Overview of the Krebs or citric acid cycle, which is a series of reactions that takes in acetyl CoA and produces carbon dioxide, NADH, FADH2, and ATP or GTP.

The Krebs cycle itself actually begins when acetyl-CoA combines with a four-carbon molecule called OAA (oxaloacetate). This produces citric acid, which has six carbon atoms. This is why the Krebs cycle is also called the citric acid cycle.May 15, 2020

If the DNA sequence was a AGC what would the mRNA sequence be?

Answers

Answer:

DNA utilizes four bases, adenine (A), guanine (G), cytosine (C), and thymine (T), in its code. RNA also uses four bases. However, instead of using 'T' as DNA does, it uses uracil (U). Therefore, if your DNA sequence is 3' T C G T T C A G T 5', the mRNA sequence would be 5' A G C A A G U C A 3'.

Answer:

Explanation: The car with the smaller mass will require less force to stop than The car with the larger mass that is it

The car with the smaller mass will require less force to stop than the car with the larger mass.

What is law of inertia?

The law of inertia or Newton's first law of motion states that an object at rest or uniform motion in a straight line will continue in that form unless it is acted upon by an external force.

This law is called the law of inertia because it depends on mass of the object.

The object with more mass will required more force to be stopped while the object with less mass will require less force to be stopped.

Thus, the car with the smaller mass will require less force to stop than the car with the larger mass.

What molecules will carry the electrons to the electron transport chain?

Answers

Answer:

electron and nuetrons

The molecules NADH and FADH₂ will carry the electrons to the electron transport chain.

These electron carrier molecules (NADH and FADH₂) are produced during the breakdown of glucose and other energy-rich molecules in the preceding steps of cellular respiration. They carry the high-energy electrons derived from these molecules to the electron transport chain, which is embedded in the inner mitochondrial membrane in eukaryotic cells.

The electrons passed through the electron transport chain ultimately combine with molecular oxygen to form water, which is the final electron acceptor in the chain.
