Answer: B) thiamin
Explanation:
Thiamine (vitamin B1) acts on carbohydrate, fat and protein metabolism, acting as a coenzyme - thiamine diphosphate. This , in combination with phosphorus, forms coenzyme thiamine pyrophosphate (TPP), which is the key to various reactions such as the transformation of glucose into energy (ATP). TPP acts as a coenzyme in the oxidative decarboxylation of pyruvate, forming acetate and acetyl coenzyme A that is required for carbohydrate, fat and protein metabolism.
The reason it’s ineffective to prescribe antibiotics to treat colds or the flu is because antibiotics treat bacteria, and the flu is a virus. I hope that helps!!
Plants have sex. It’s true. While it may only be a vaguely similar process to the sex participated in by humans and animals, plants engage in sexual reproduction quite often. There is a series of steps that plants go through to create offspring. It isn’t the most romantic process, but it can be fascinating nonetheless. Learning how plants reproduce sexually can give you a better understanding of the life cycle of the various plants species. The flowering plant is the easiest to understand.
Pollination is the first required step in sexual plant reproduction. The male portion of the plant produces the pollen—typically in the flower. A long filament, called a stamen, holds the bits of pollen at the end and one of several pollinators take the pollen to the female part of the flower, called the pistil. Pollinators can be insects or birds drawn to the plant by the colorful flowers and fragrance for the nectar inside. As they enjoy the plant, the pollen sticks to their bodies and is carried away to another flower that may contain the pistil. The wind can also carry pollen to other flowers, as can water in some species. Some plants have male and female parts on the same flower and can self-pollinate. In any event, pollination requires the movement from the stamen to the pistil so reproduction can continue.
Correct answer choice is:
A. All of the answers are correct.
Explanation:
The value of making ourselves for emergencies is terrestrial. Accidents can occur anyplace - at the residence or on the job - and everyone must take a step to plan for emergencies in case something suddenly appears.
No matter wherever you live, it's necessary to have an emergency equipment kit immediately ready for use. This kit should cover things you would require to persist for various days, and should be simply transportable. Say, if you need to move suddenly, you should be able to take this kit with you and go.
