Answer:
Sarcomere
Explanation:
Myofibril is the unit of the muscle cell. The myofibril is rod like in structure and developed by the process of myogenesis in embryo.
Sarcomere is the basic structural unit of the skeletal muscles and shows striations under the microscope. Sarcomere consists of thick and thin filaments of actin and myosin. Different bands like A- band , H-Band, I-Band and Z- line is visible in the sarcomere.
Thus, the correct answer is option (A).
Answer:
Explanation:
mammal(X) :- legs(X,4), arms(X,0).
mammal(X) :- legs(X,2), arms(X,2).
mammal(horse).
arms(horse,0).
As far as I can tell, prolog cannot derive that a horse has four legs. Why so? You may ask. I'd say then, because there isn't any rule(s) for prolog to use in determining the legs. Inference rules can also not be used to determine that the fact that a horse is a mammal and it has 0 arms, it certainly must have 4 legs.
The red blood cells are cohesive, meaning they want to stick together. if one cell moves along the capillary this cohesion will drag the neighboring cell with it. the cells are also adhesive to the capillary walls, so they stick along the tube lining as they are dragged through the capillary.
Answer:
Many rare and/or endemic species exhibit one or more of the following attributes which make them especially prone to extinction: (1) narrow (and single) geographical range, (2) only one or a few populations, (3) small population size and little genetic variability, (4) over-exploitation by people
Understanding the nutritional content of food is important to maintain a balanced diet, manage weight, and control health conditions like diabetes or high blood pressure.
Understanding the nutritional content of food is crucial for several reasons. Firstly, it helps you to maintain a balanced diet, which is necessary for optimal health.

Coral reefs are some of the most diverse ecosystems in the world. It is produced by Coral polyps and may occur as barrier, fringing, or atoll formations.
Coral reefs protect coastlines from storms and erosion, it is a rich source of job for local communities, and provides avenues for recreation. It is rich in food nutrients and can be used medicinally too.
It exhibits mutualism with photosynthetic algae called zooxanthellae. It supplies shelter and safety and materials needed by zooxanthellae for photosynthesis while it obtains nutrients and oxygen and waste removal mechanism from it.
Answer:
This is for the offspring to show traits that come from both the mother and father.
Explanation:
Gametes are formed by a kind of cell division called meiosis in which the chromosome number is halved. Thus the said gamete cell is said to contain a haploid number of chromosomes.
The fusion of two haploid gametes is called fertilization. It results in the formation of single celled zygote which has a diploid number of chromosomes. The zygote now divides and develops to produce the offsprings whose somatic cells are diploid.
