Answer:
No ATP is available to release attached actin and myosin molecules.
Explanation:
Two to six hours later after death, all skeletal muscles of the body become rigid and stiff. This situation is defined as Rigor mortis. It occurs from the lack of ATP along with the production of lactic acid. When breathing stopped permanently in the body, oxygen level also reduced; that’s why body muscles cannot go for any aerobic respiration to produce any ATP.
As we know already, during every muscle construction, ATP needs to break the cross-bridge between Myosin and Actin. So if there is no ATP produced in the body, separation of Myosin molecules from Actin molecules cannot happen anymore. This situation leads for rigor mortis.
Answer:
B: Plants use carbon dioxide and release oxygen during photosynthesis
Explanation:
It represents the dominance.
<span>The dominance occurs when an allele (dominant) that is expressed in an organism’s phenotype, masks the effect of the recessive allele that is also present. In this case allele for brown coat color (F) is dominant to the allele for white coat color (f). When these two alleles are together (genotype is Ff) the brown color will be expressed as a phenotype.</span>
Answer:
Mushrooms belong to the Kingdom Fungi.
Explanation:
Fungi are eukaryotic organisms that act as the main decomposers in the environment. Examples are yeasts, molds and mushrooms. Black truffles are aromatic edible fungi that belong to the Ascomycota phylum.
Mushrooms belong to the Basidiomycota phylum. Mushrooms are saprophytes, as they have no chlorophyll and obtain their food from metabolizing nonliving organic matter.
Edible mushrooms include commercially raised mushrooms like button mushrooms, portobello mushrooms, straw mushrooms, oyster mushrooms, shiitakes, enokitake, etc and wild-harvested mushrooms such as black trumpets, milk mushrooms, porcini mushrooms, morels, chanterelles, etc.
Poisonous mushrooms include amanita, galerina, conocybe, lepiota, etc. They contain deadly poison which causes a range of reactions such as hallucinations, allergic reactions, digestive problems, severe organ failure, and death.
