svp [43]

Answer:

Some benefits of plastic are that plastic packaging helps protect and preserve goods, while reducing weight in transportation, which saves fuel, reduces greenhouse gas emissions and are low in cost.

Some disadvantages are that toxic chemicals can leach out of plastic and can be found in the blood and tissue of nearly all of us. Exposure to them is linked to cancers, birth defects, impaired immunity, endocrine disruption and other ailments

What are the subunits called that make up carbohydrates?

neonofarm [45]

Answer:

Carbohydrates are used by the body for energy and structural support in cell walls of plants and exoskeletons of insects and crustaceans. They are made of smaller subunits called monosaccharides. Monosaccharides have carbon, hydrogen, and oxygen in a 1:2:1 ratio.

Difinition of disaccharides: any of a class of sugars whose molecules contain two monosaccharide residues.

Make an example...

Short carbohydrate chains are called oligosaccharides and contain 3 to 10 sugar molecules. Long carbohydrate chains can contain hundreds or even thousands of monosaccharide units. molecule of glucose and one molecule of fructose joined together.

Solve for v negative 38= v/2

Nadusha1986 [10]

$- 38 = \frac{v}{2}$

$\text{Multiply by 2 on both sides, }$

$2 \times ( - 38) = \frac{v}{ \cancel{2}} \times \cancel{2} \\ \\ \\ \\ = > - 76 = v \times 1 \\ \\ \\ = > - 76 = v$

So, value of v is - 76

What is the energy brought by electron carriers to the mitochondria used for?

Nonamiya [84]

Answer:

The correct answer will be- to synthesise the ATP molecules in respiration process.

Explanation:

The electron transport chain is the last phase of the cellular respiration which helps in the synthesis of a large number of ATP molecules.

The ATP molecules are synthesized when the energy generated by the movement of protons through CF₀ unit takes place.

The movement of electrons in the chain leads to the movement of proton from the mitochondrial matrix to the intermembrane space. This creates the proton gradient across the membrane which to equilibrate the protons move down the concentration gradient through ATP synthase. The energy while this is used to rotate the ATP synthase which coverts the ADP to ATP.

Thus, to synthesise the ATP molecules in the respiration process.
