Question 4
Juliette [100K]

Answer:

In eukaryotes, thousands of chemical reactions are able to take place in  separate compartments called organelles.

Explanation:

Organelles are specific cellular structures that are the means of compartmentalizing the various functions that occur within cells.

Examples of organelles and their functions are:

- <u>Nucleus</u>: contains DNA and in it occur the replication of this molecule and its transcription into RNA.

- <u>Rough endoplasmic reticulum</u>: protein synthesis and conjugation of these molecules occurs.

- <u>Mitochondrion</u>: houses all oxidative phosphorylation reactions and the electron transport chain for ATP synthesis to occur.

The organelles are then the structures that allow the development of the multiple functions that a cell has.

The other options are not correct because:

  • <em><u>Bacteria</u></em><em> is a prokaryotic organism. </em>
  • <em><u>Prokaryote</u></em><em> refers to simple organisms that lack organelles. </em>
  • <em><u>Proteins</u></em><em> are biomolecules that allow the structure and function of living beings.</em>

Naddika [18.5K]

Answer:

A possible hypothesis would be:

IF a yeast cell is supplied with maltose sugar, THEN it would yield the greatest amount of energy when metabolized by bacteria

Explanation:

The hypothesis is a testable explanation aimed at providing a theoretical explanation to a question. The hypothesis is a predictive statement about the possible solution, which can be tested. A hypothesis must be testable via experimentation. It often has an IF, THEN format.

Hence, in the case experiment where a student wanted to know which sugar (maltose, glucose or sucrose) would yield the greatest amount of energy for the cell when metabolized by mitochondria. A possible hypothesis of this experiment will be that: IF a yeast cell is supplied with maltose sugar, THEN it would yield the greatest amount of energy when metabolized by bacteria

Note that, this hypothesis must be testable by conducting an experiment and it doesn't have to be true. It can be disproved or proved by the outcome of the experiment. In this case, the hypothesis is giving an educated guess that maltose is the sugar that will yield the greatest amount of energy for yeast cells

Count up the number of atoms on each side of the equation below and write this in the chart.
ivann1987 [24]

Answer:

The equation to this question is unclear. The clear equation is:

CH4 + 2O2 → CO2 + 2H2O

Please find the number of atoms of each element on the reactant and product side below.

Explanation:

An atom is the smallest indivisible part of an element. The atom retains the chemical properties of the chemical element. In order to ensure that a chemical reaction between molecules and compounds is BALANCED, the number of atoms of each element that makes up the molecule/compound must be the same on both the reactants and products side.

In this case, the chemical reaction involves:

CH4 + 2O2 → CO2 + 2H2O

1. Carbon atom (C):

Reactants side = 1 atom

Products side = 1 atom

2. Oxygen atom (O):

Reactants side = 4 atoms

Products side = 4 atoms

3. Hydrogen atom (H):

Reactants side = 4 atoms

Products side = 4 atoms
