Answer: The function of of E and F is the sum or product of two E-functions is an E-function. In particular E-functions form a ring. If a is an algebraic number and f(x) is an E-function then f(ax) will be an E-function. If f(x) is an E-function then the derivative and integral of f are also E-functions.
Explanation:
I think the answer is a but I am not sure
Answer:
spinach plants will be more genetically diverse than tomato plants because sexual reproduction generates more genetic diversity than asexual reproduction
Explanation:
In nature, there are two basic mechanisms of reproduction: sexual reproduction and asexual reproduction. Genetic variation can be generated by the following mechanisms: mutations, random fertilization, recombination (i.e., crossing over), and the independent assortment of homologous chromosomes during meiosis. Sexual reproduction involves two parents, thereby new genetic variation can be generated in the offspring through all these mechanisms: new mutations, genetic recombination (which generates new alleles within an organism's offspring), random fertilization, and the random (independent) assortment of homologous chromosomes during meiosis (these last two mechanisms can potentially generate new genetic combinations in the offspring). Moreover, asexual reproduction involves a single parent, and thereby in this case genetic variation can be only generated by mutations that are passed on to offspring.
When alzheimer disease appears in middle age rather than old age; it progresses more rapidly. Alzheimer's disease that results from the brain cell death. It is a neurodegenerative disease; such that there is progressive brain cell death that happens over a period of time. The brain tissue gets fewer and fewer nerve cells and connections.
The muscles that contract (during cold or fright), the slanted hair follicle is pulled upright, dimpling the skin surface with goosebumps are called arrector pili muscle.
The arrector pili muscle are tiny muscle that attaches to the base of the hair follicle at one end and to the dermal tissue on the other end. When the body feels cold or fright the body generate heat and the arrector pili muscle contract all at once, that causes goosebumps on the skin.
The arrector pili muscle acts as the thermoregulator. Straight stand hair increases air trapping, so that the heat loss from the body decreases. The arrector pili muscle are mediated by the sympathetic nervous system.
