Nonamiya [84]

Answer:

You can use either your answer or the sample answer you gave. You are so nice by the way!

Explanation:

THE FOLLOWING ARE TWO ANSWERS YOU CAN CHOOSE FROM

ANSWER 1:

The red crystals are compounds. This is because when the sample is heated, a GAS (element) is released and BLUE POWDER (element) is left. Two elements make up these red crystals. A compound can also be shown through color change - the RED crystals, when heated, turn into BLUE powder. Elements cannot be broken down into substances using physical force, like heating. So yes, this is a compound.

ANSWER 2:

The red crystals are compounds. This is because when the sample is heated, a GAS (element) is released and BLUE POWDER (element) is left. Two elements make up these red crystals. A compound can also be shown through color change - the RED crystals, when heated, turn into BLUE powder. Elements cannot be broken down into substances using physical force, like heating. So yes, this is a compound.

EITHER ONE YOU CHOOSE WILL BE CORRECT, JUST SAYING!

Which choice has eukaryotic animal cells? 1- oak 2- liver 3- virus 4- Lactobacillus
ipn [44]

Answer:

Liver

Explanation:

Eukaryotes are organisms that are made up of cells that have a membrane-bound nucleus. They are commonly described as cells with a "TRUE" nucleus. Animals and plants are eukaryotes.

Since it says "Animal" we can cross out oak, because this is a plant. Viruses are not cells, they are not considered living organisms as well. Lactobacillus is a type of bacteria and bacteria is classified as prokaryotic.

Prokaryotes are different from eukaryotes because they lack that membrane-bound nucleus.

The gas exchange during cellular respiration involves _____ moving into cells and ____ moving out of cells. The gas exchange dur
ludmilkaskok [199]

The gas exchange during cellular respiration involves oxygen moving into cells and carbon dioxide moving out of cells.

During gas change oxygen actions from the lungs to the bloodstream. on an equal time, carbon dioxide passes from the blood to the lungs. This happens within the lungs among the alveoli and a network of tiny blood vessels known as capillaries, which might be located in the walls of the alveoli.

Three strategies are critical for the switch of oxygen from the out of doors air to the blood flowing through the lungs: airflow, diffusion, and perfusion. ventilation is the manner through which air moves in and out of the lungs.

The lungs and respiratory system permit us to respire. they create oxygen into our bodies (called a concept, or inhalation) and send carbon dioxide out (referred to as expiration, or exhalation). This alternate of oxygen and carbon dioxide is referred to as respiratory.
