Dr. kitty hauke is studying lobsters in maine. she noticed that over several years the average length of pincers had increased w

ithin this population. she hypothesized that having larger pincers provided a fitness advantage. to test her hypothesis, she introduced 75 large pincer lobsters and 75 small pincer lobsters into an isolated bay area that was similar to the lobsters' natural sea environment. over 10 years, dr. hauke observed this isolated population of lobsters. what would she likely observe if her hypothesis was incorrect?

Answer:

If the hypothesis was incorrect then the percentage of the large lobsters with large pincers would decrease.

Further information:

How this hypothesis was incorrect?

If her hypothesis was incorrect the percentage of the large lobsters with large pincers would decrease. The large pincers help the lobsters to quickly catch their pray efficiently. This would mean the survival of the lobsters with large pincers. A wrong hypothesis would mean that the large pincer lobsters would die and decrease in number.  

Dominant claw of lobster:

Each lobster has two different claws, a longer crusher claw and a smaller pincher claw. The crusher claw has a ridged edge that look like molars and is used to break up hard food such as clams and crabs. The pincher claw, or ripper claw, is used to scratch apart softer prey such as worms or fish. These claws can be on altered sides of a lobster's body, as the crusher claw is always on the lobster's overriding side.

Dominik [7]

Answer:

Hazel - 1/4 or 25%

Green - 1/2 or 50%

Blue - 1/4 or 25%

Explanation:

First, let us carry out the cross between AaBB and Aabb using a Punnet's square. The result is as below:

AABb - 4/16

AaBb - 8/16

aaBb - 4/16

(See the Punnet's square analysis in the attached image).

<em>AABb genotype has 3 pigments, hence, would be hazel.</em>

<em>AaBb genotype has 2 pigments, hence, would be green.</em>

<em>aaBb has one pigment, hence, would be blue.</em>

Expected progeny:

<em>Hazel - 1/4 or 25%</em>

<em>Green - 1/2 or 50%</em>

<em>Blue - 1/4 or 25%</em>

Red blood cells carry antigens on their surfaces coded for by alleles of the gene designated by the letter I. IA is dominant to
Marat540 [252]

Answer:

Allele IA produces antigen A

Allele IB  produces antigen B

Allele i produces No antigen

To predict the genotype the main thing is that I is dominant to i allele.

So, the ABO grouping genotype should be like this.

Genotypes                               Phenotypes

IA IA                                                A

IA i                                                   A

IB IB                                                B

IB i                                                   B

IA IB                                                AB

i i                                                      O

This the main ABO blood grouping genotyping and phenotyping used in transfusion medicine. And this is the most abundant test performed in the blood banks for transfusion of blood and record management.

A certain machine can output 50 Joules (J) of energy when 100 J of energy are input. If the amount of friction experienced by th
Makovka662 [10]

Explanation:

75 J

Energy is neither related nor destroyed- it's simply converted to different forms. Forces are vectors with both mass and acceleration; they are interactions that have the ability to change an object's motion. As objects move, their potential energy (apprx 100 J) is converted to kinetic energy. However, friction a resistive force, which is formed from the conversion of an object's kinetic energy into heat energy, as two surfaces move along each other.

With the reduction of friction, the energy output should increase, as less energy is lost as heat. Thus, the output should be 75 J.

To help explain surface tension, use a single water molecule in the template, and draw arrows representing the possible location
kramer

Answer:

The correct representation is attached with the explanation.

Explanation:

In this representation of the surface tension, blue arrows between green water molecules are the possible molecules that can be used as the location for forming hydrogen bonds by a single molecule. Surface tension is the tendency of a liquid surface strectch to neighbouring molecules or ability to shrink in minimum surface area possible. Hydrogen bonds is an intermolecular force or interaction responsible for the surface are of liquide molecules. This bonds is towards every direction where the similar molecule present.
