Answer:
the thin filaments are pulled away from one another, thereby reducing their ability to interact with myosin
Explanation:
The myofibril is the basic unit of a muscle cell. Each myofibril is composed of contractile units known as sarcomeres which may contain two different types of myofilaments: thick myofilaments and thin myofilaments. The thick filaments are known to have a constant length, and they consist especially of myosin proteins. These filaments (thick) do not extend to the ends. On the other hand, the thin filaments extend in from each end, and they are mainly composed of actin proteins that serve as tracks for the movement of myosin proteins.

Sickle-shaped red blood cells result from a mutation in the gene that codes for hemoglobin. This mutation results in sickle-cell anemia. A partial sequence of bases from a normal hemoglobin gene and a sequence that results in sickle-cell anemia are shown below
Complete question: Sickle-shaped red blood cells result from a mutation in the gene that codes for hemoglobin. This mutation results in sickle-cell anemia. A partial sequence of bases from a normal hemoglobin gene and a sequence that results in sickle-cell anemia are shown below (the diagram is in the attached file)
What type of mutation is depicted in this sequence?
Answer:
The type of mutation is known as SUBSTITUTION.
Explanation:
Sickle cell anaemia is an inherited disease caused by abnormal shape of the red blood cell. This abnormal red blood cell contains less haemoglobin and cannot transport oxygen efficiently round the body. Sickle-shaped (abnormal) red blood cells result from a MUTATION in the gene that codes for hemoglobin.
Mutation is the random changes in DNA that alters genetic information and so introduce new characteristics. The different categories of mutations include:
--> Chromosomal mutation and
--> Point mutation.
SUBSTITUTION is a type of point mutation in which one base is incorrectly added during replication and replaces the pair in the corresponding position on the complementary strand. From the diagram, a partial sequence of bases from a normal hemoglobin gene and a sequence that results in sickle-cell anemia, shows a substitution of an A for the middle T. This leads to GUA in the messenger RNA, which specifies the amino acid valine. The substitution of valine for glutamic acid at this particular position alters the chemistry of the hemoglobin such that it sticks together if it is not binding oxygen, creating sickling of the red blood cells.

Why do rats have three lobes of liver and humans only have one?
Answer:
Although the rat liver is typically lobated2 and its ap- pearance does not resemble that of the human liver, the hepatic lobes of the rat liver have been found to be equivalent to the sectors of the human liver. As rats and humans belong to the class Mammalia, similar em- bryological development is expected.

How are cardiac muscle cell and a nerve cell similar and different?
Answer:
Both are similar due to origin of the membrane voltage and impulse propagation whereas both are different in their function.
Explanation:
Cardiac muscle cell are similar to a nerve cell because both have the same origin of the membrane voltage and impulse propagation also occurs in the same manner whereas, cardiac muscle cell is different to a nerve cell because cardiac muscle cells form the cardiac muscular system while nerve cells form the nervous system. Muscle cells are responsible for the contraction and relaxation of heart while on the other hand, nerve cells are responsible for the transmitting of nerve impulses throughout the body.

b. Respiratory system
c. Nervous system
d. All of the above
Answer:
No. B

I hope it helps ✌️
Explanation:
Parasitic flatworm do not have a digestive system because they don't digest there food. They just suck it when the upper gut muscles contract, suck it inside their body then gobble them up and then they're done sucking the nutrients from the food people eat.
Answer:
A. Digestive system

Reptiles have dry, tough skin covered in scales, which reduces water loss. Reptiles breathe using lungs; they do not exchange gases through their skin. Their kidneys also help prevent water loss by concentrating their urine. Young reptiles develop inside an amniotic egg, which is covered with membranes and a shell to prevent it from drying out.
