Answer: eating foods that will give you the proper nutrition
exercising
getting plenty of rest
Explanation:
The answer is; Ca2+ from the sarcoplasmic reticulum binds to tropomyosin
When the ca2+ ions bind to the tropomyosins on the actin filament, the tropomyosins are displaced and this exposed the myosin binding sites on the actin filament. The ADP + Pi (attached to the myosins heads), from the previous cycle, is released allowing the cocking of the myosin heads hence pulling on the actin filament. ATP then binds on the ATP-site on the myosin heads casing a release of the myosin heads from their site in the actin. This also hydrolyzes the ATP. This is one cycle of the cross-bridge cycle.
Answer:
a) HT
Explanation:
This question shows an animal with two distinct unlinked genes i.e. on different chromosomes. One gene codes for head shape and the other for tail length. The gene for head shape possess alleles H and h, while gene for tail length possess alleles T and t.
According to Mendel's law of independent assortment, the alleles of a gene will separate into gametes independently of the alleles of another gene. This occurs in such a way that each gamete will contain only one allele from a gene.
Based on this principle, an animal with genotype HhTt will undergo meiosis and randomly produce gametes with the following allelic combinations: HT, Ht, hT, and ht. As seen in the gametes, only one allele of a gene occured in a gamete at a time.
Therefore, HT is the genotype possible in a gamete of parent: HhTt.
Plant cells have several structures not found in other eukaryotes. In particular, organelles called chloroplasts allow plants to capture the energy of the Sun in energy-rich molecules; cell walls allow plants to have rigid structures as varied as wood trunks and supple leaves; and vacuoles allow plant cells to change size.
