Biology
1 answer:
Fittoniya [83]2 years ago
6 0

Answer:

The probability that this couple will have a child with Duchenne Muscular Dystrophy is 50/50

Explanation:

This Punnett square shows our woman as "xx" and our man at "xy". Knowing this, we can now look back at the Punnett square's results. Out of the four squares, two of them are fill with the woman's carried condition, but the other two are also filled with the man's. So, that leaves us with a 50 percent chance that their child will have DMD.

Hope this helped!

What the process and energy needed?
leva [86]

Answer:

C. Diffusion and no energy needed.

Explanation:

A - Passive transport doesn't require energy.

B - Osmosis would be if the 25% H2O went into the 82%

D - Active transport doesn't apply because molecules aren't moving across into a higher concentration.

Diffusion is when parts of the 82% go into the 25%.

Many cells make and use an enzyme, called catalase, to facilitate the decomposition of hydrogen peroxide (H2O2). The products of
Len [333]

Answer:

A. It decreases the activation energy needed to start the reaction

Explanation:

Organic catalyst which speed up the rate of organic chemical reaction is living cells are called enzymes.They have specific reaction site called active sites.This must be in prefect shape with the substrate for the organic chemical reaction to take place

When this occurs the minimum amount of  energy of  reaction to  activate or stimulate  the the atoms and molecules of the substrate to undergo chemical reaction is  lowered.This energy of reaction is celled activation energy.

Catalase thought its active sites lowers the activation energy so that the molecules of H2O2 could break down to C02 and H2 faster,thereby reducing the time for theses product to form.The is the general roles of enzyme.To increase the rate of chemical reaction,by reducing the activation  energy.

Density is mass per unit of volume. Which pair of lab instruments would a student use to measure the density of seawater?
9966 [12]
<h3>Answer:  C. a balance and a beaker</h3>

Explanation:

A balance would be used to measure the weight, which in turn effectively measures the mass (more or less). Imagine that we have a brick that we know is 1 pound. If we have an object that needs 5 bricks on one side to balance it out, then we know the object is 5 pounds.

The beaker is used to measure the volume. It's basically a measuring cup that you would find in the kitchen.

To get the density, you divide the mass over volume.

For example, if you have a material that has a mass of 100 grams and it's volume is 20 cm^3, then its density is 100/20 = 5 grams per cm^3.
