Answer:
The correct answer is - per gram, the marathon runner's muscles would contain more myoglobin than the sprinter's muscles.
Explanation:
Marathon runners have smaller leg muscles and thinner quads and calves as marathon runners require slow-twitch muscles while in sprinters the fast-twitch muscle requires. Slow-twitch muscles of marathon runners have more amount of myoglobin, per gram than fast-twitch muscles.
Myoglobin acts as local oxygen storage that provides oxygen to the muscles in case of less oxygen supply than required temporarily and a marathon race is an intense exercise or activity that requires more oxygen.
Answer:
It consists of the mouth, or oral cavity, with its teeth, for grinding the food, and its tongue, which serves to knead food and mix it with saliva; the throat, or pharynx; the esophagus; the stomach; the small intestine, consisting of the duodenum, the jejunum, and the ileum; and the large intestine, consisting of the cecum, a closed-end sac connecting with the ileum, the ascending colon, the transverse colon, the descending colon, and the sigmoid colon, which terminates in the rectum. Glands contributing digestive juices include the salivary glands, the gastric glands in the stomach lining, the pancreas, and the liver and its adjuncts—the gallbladder and bile ducts. All of these organs and glands contribute to the physical and chemical breaking down of ingested food and to the eventual elimination of nondigestible wastes.
Answer:
1. lungs
2. skin
3. large intestine
Explanation:
lungs inhale oxygen
skin is on the outside of the body
the large intestine processes your food into feces
Answer:
The correct answer will be- Non-Mendelian inheritance (incomplete dominance)
Explanation:
Incomplete dominance is a type of inheritance pattern observed in nature in which none of the two alleles completely show their effect and produces a third type of phenotype which is different from the phenotype of both the parents.
In the given question, since the cross of red flower and white flower produces a third type of flower color known as pink during F₁ generation is the result of the incomplete effect of both the alleles.
Cross
RR (red) x rr (white) = Rr (pink)
Thus, incomplete dominance is the correct answer.
Answer:
Gametophyte
Explanation:
This is is the dominant phase of moses (division bryophyte) and other lower plants such as pteridophytes and liverworts. The gametophytes produce haploid spores. When two diploid spores fuse into a zygote, it grows into a sporophyte, usually attached to a gametophyte, because it depends on it for water and nutrient. The sporophyte then produces haploid spores that give rise to gametophytes. The diploid phase is significant because it gives opportunity for recombination of genes which provides genetic variation among the moss.
