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.
A complicated substance with significant heterogeneity is trabecular bone. Depending on the anatomical region and with age, its elastic and strength qualities change significantly also sickness.
The relevance of architecture and tissue material qualities is still unclear, despite the fact that these characteristics are highly dependent on density. Interesting facts about the strains the point at which the bone fails is essentially independent of density. Currently being done, there are more sophisticated structure-function relationships that underlie such behavior mechanical characteristics such time-dependent failure, damage, and multiaxial loading accumulation.
The microstructural class of finite element models, especially the "high-resolution" models, offers a special method for investigating such phenomena. With continuing research in this area, it is anticipated that significant understanding will be gained into issues including osteoporosis, bone fracture, bone remodeling, and the design/analysis of bone-implant systems. This article examines the current status of trabecular bone biomechanics, concentrating on the mechanical elements, and makes an effort to pinpoint crucial areas for present and future study.

<span>1. Protozoa are single celled, eukaryotic organisms that exhibit animal-like behaviour.
2. Viruses consists only of genetic material and a protein coat, and they are known to cause a wide variety of diseases such as AIDS.
3. Fungi have characteristics similar to plants, but they do not have root systems like plants do and they also do not rely on chlorophyll to photosynthesize.
4. Bacteria make up this category.
5. Rickettsiae is a genus of bacteria that are intracellular parasites.</span>
Answer:
Musclar dystrophy.
Explanation:
It is caused by interferences (mutation)with the protein(gene sequnce) for formation of healthy muscles. Therefore leading to abnomaliteis in muscles cells formation and functions
Two major types most common in males than females:
Becker muscular dystrophy, Duchenne muscular dystrophy.,etc.
Most symptoms includes;
Muscle stiffness, frequent falls, walking on toes, learning disabilities etc.
Answer:
The total number of chromosome in a skin cell is equal to 78
Explanation:
The sperm is usually haploid i.e it will contains only half of the total chromosome number.
Therefore , if the total number of chromosomes is "n" , then the number of chromosome in the sex cell will be "n/2"
Thus, 39 chromosome is just the half of total chromosome number.
Now a skin cell is a diploid cell and it will contain all the chromosome i.e "n"
As we know

Hence, the total number of chromosome in a skin cell is equal to 78
