Answer: Small intestines

Explanation: Digestion of carbohydrates begins in the mouth mechanically and through salivary amylase. It passes down to the stomach by parastalsis, digested further and goes to the small intestines where their absorption begins. Carbohydrates are a source of glucose, that most organs use as their primary energy source. Indigestible carbohydrates and fibers travels down to the large intestines where they are digested by bacteria or eliminated as waste through the anus.

The small intestines consist of microvilli that increase surface area for maximum nutrient absorption. Carbohydrates are absorbed by the small intestines via the jejunum, taken to the blood stream then transported to the liver where glycolysis and most metabolic pathways take place, for energy production.

Which particles are located in the nucleus?

pentagon [3]

Answer:

$\boxed {\boxed {\sf Protons \ and \ neutrons }}$

Explanation:

In an atom, there is a dense center known as the nucleus. It is made up of two subatomic particles: protons and neutrons. The protons have a positive charge and the neutrons have no charge, so overall the nucleus is positively charged.

The third subatomic particles, negatively charged electrons, are located around the nucleus in a cloud.

The particles in the nucleus are $\tt protons \ and \ neutrons$ .

Why is it correct to say that only green plants do photosynthesis but not correct to say that only animals do respiration?

My name is Ann [436]

Plants respire all the time because their cells need the energy to stay alive, but plants can only photosynthesize when they are in the light

A second action potential cannot be generated until ________.

Bingel [31]

Answer:

"Action potential is a rapid rise and subsequent fall in voltage or membrane potential across a cellular membrane with a characteristic pattern."

It is the mode through which a neuron transports electrical signals.

Explanation:

Option - (a) is the best choice to choose from,

The refractory period :

A second action potential cannot occur until the membrane has recovered or reestablished, this is the refractory period. The absolute refractory period coincides with inactivation of voltage-gated sodium channels which makes it impossible to generate another nerve impulse.

Which of the following options correctly describes the behavior of a tetrad during anaphase 1 of meiosis?

Svet_ta [14]

The answer is; C

Homologous chromosomes have the same genes on the same loci. However, they may have different forms of the same gene called alleles. These sister chromosomes, of a homologous pair, separate during anaphase I of meiosis. The two daughter cells formed will, therefore, have half the genetic material as the parent cell. This is because they will only have one set of the genes (as in diploid organisms) and are called gametes.
