If no ATP is present in the muscle cell what would be the likely result?

Elden [556K]

Answer: c. The myosin would not be able to let go of the actin

Explanation:

Muscles consists of two proteins called actin and myosin and responsible for muscle contraction.

Myosin is ATP dependant and when ATP binds to it, it is able to release the actin.

This will allow the actin and myosin to seperate from each other thus leading to muscle contraction

According to the cladogram, which characteristic was used to separate bony fish from amphibians?

noname [10]

Answer:

(D). lungs

Explanation:

Cladograms are diagrams that show cladistic relationship between organisms of different species on the basis of their characteristics. The cladograms may include characteristics to make two organisms different from each other.

In given cladogram, characteristic that separates bony fish from amphibians is 'lungs', as lungs are absent in bony fishes, while present in amphibians.

Thus, the correct answer is option (D).

Which describes an interaction in which two organisms that interact must use the same limited resources?

pogonyaev

Answer: competition

Explanation:

Competition is an ecological interaction in which two organisms interact with each other in order to obtain the same resource. The resource can be food, shelter, mate or other. The competition can be intraspecies which means the members of the same species compete for the resources. The competition can be interspecies which means members of the two distinct species compete for the same resource. Generally the competition leads to the decrease in growth, abundance and distribution of members of the inferior species and the members of the superior species derives the resources.

Analyze the data about nitrogenous base content of DNA from various species. Percentages of Bases in Five Organisms Source of DN

Troyanec [42]

Answer:

When analyzing data on the nitrogenous base content of the DNA of various species, the claims are supported by the data:

In any one species, the amount of adenine closely approximates that of thymine.
In any one species, the amount of guanine closely approximates that of cytosine.
The amounts of A, T, G, and C in DNA varies from species to species.

(options A, B and D)

Explanation:

Organizing the data has to:

Source of DNA A T G C

Streptococcus 29.8 31.6 20.5 18.0

Yeast 31.3 32.9 18.7 17.1

Herring 27.8 27.5 22.2 22.6

Human 30.9 29.4 19.9 19.8

E. Coli 24.7 23.6 26.0 25.7

DNA is the molecule that contains the genetic information of each species, formed by sequences of nitrogenous bases Adenine, Thymine, Cytosine and Guanine.

Since Adenine and Thymine -as well as Cytosine and Guanina- are complementary, the percentage of them will be very similar in each DNA molecule.

The genetic information -which determines the physical and functional characteristics of each organism- is encoded in the DNA and is different for each species, so the percentages of nitrogenous bases vary from species to species.

What part of the femur articulates with the tibia to form the knee joint?

dybincka [34]

Answer:

The patella articulates with the tibia to form the knee joint. 

Explanation:

Patella is called the knee cap and it gives protection to the knee. Femur is the longest bone in the body and has the function of supporting the weight of the body and enhancing the movement of the legs. The knee joint permits the extension of the lower leg relative to the thigh. 

It allows a 120 degree movement unlike other joints that allow lesser freedom of movement. Patella is the part of the femur that articulates with the tibia and forms the knee joint.
