Answer:
Cystic fibrosis mutation is recessive to normal allele because only one functional or normal allele is enough to produce a functional protein. So, if mutation is present in one allele then also, a normal protein can be made from normal allele. The presence of normal protein prevents the expression of disease.
In addition, mutated allele only results in the loss of function of protein which can be compensated by the expression of normal allele. It does not add any toxic effect to the protein. Consequently, the disease is inherited in autosomal recessive fashion.
In contrast, Huntington mutation not only alters the structure of the functional protein but also adds toxicity to it. The altered protein is enable to interact with 100s of other proteins and inhibit or decrease their function. So, if only one allele is present then also, the mutated protein will be produced and it will result in the phenotype. Consequently, it is inherited as autosomal dominant fashion.
What is Mutualism ? Mutualism or symbiosis mean when two or more animal benefit to each other.like america red tail eagle and eagle, and the zebra and Oxpeckers eat ticks and other parasites that live on their skin of the zebra and the zebra will help the Oxpeckers by walking long place.
What is predation? predation or parasitic mean when animal who is prey eat not prey.or predation is when a animal hunt the other animal for food (prey).example like the lion eat the deer.
What is Competition? Competition or commensalism is when two animal fight for the same food like chipmunks vs squirrel, because the chipmunks like to eat nut and the squirrel eat nut they fight for the same resource.
Answer:
The correct answer is D) dendrites; cell body; axon
Explanation:
Neurons cells makes the nervous system and are responsible for carrying the information from one body part to the other body parts. A neuron has three distinct parts dendrites and axon.
Dendrites are the neurons extension which receives the impulse and transfers to the cell body. We can link dendrite with our fingers. Cell body is a spherical part of neuron like our palm and it controls all functions of the cell. Then from cell body signals are transferred to axons.
Axon is a long part of the nerve cell like our hand which helps in transmitting the signals to the next neurons. Therefore the correct answer is D.
