What do you think will happen to you if your mitochondria do not work efficiently?
Answer:
For our bodies the conversion from food energy to ATP happens in mitochondria. If your mitochondria are not working properly then you are less able to convert food into ATP. For cells that require a lot of ATP, for example your muscles, this is a problem and they may become weaker and get tired faster.

Answer:
B. The two stages of photosynthesis are light-dependent reactions and the Calvin cycle.
C. Glucose is also known as sugar that is found in our blood. Glucose is important because it provides energy in our body so that we do not faint. For example, when someone faints, the first thing is to give glucose to that person than water because glucose produces a lot of energy to our body faster than water. This is also the answer of why we need glucose.
Hope this helps, thank you !!

When hydrogen and oxygen combine to form water, water is
a an enzyme.
b a catalyst.
c a reactant.
d a product.
Answer:
D. A product.
Explanation:
The water can't be an enzyme, catalyst or reactant because it was not present before or during the reaction. It was only present after the reaction, so it is a product.

Mitosis Inquiry Activity (10 points) 1) In the space below, sketch your group consensus pictures then write the verbal interpretation, percent of cells and name to use for each stage. Snip/Sketch,,Verbal Interpretation,Name of phase,Percent of cells
Answer:
Prophase, metaphase, anaphase, and telophase.
Explanation:
Mitosis is a type of cell division in which a single mature parent cell is divided into two daughter cells having double number of chromosomes and identical to parent cell. There are four phases of mitosis which are prophase, metaphase, anaphase, and telophase. During prophase phase, chromatin condenses into chromosomes. During prophase phase, the chromosomes of the cell align themselves in the middle of the cell. During prophase phase, During prophase phase, the splitting of chromosomes occur and the separated chromosomes goes to the opposite poles of the cell. During telophase, it results in the production of two nonidentical daughter cells.

What types of skills do the Wechsler subtests measure?
Answer:
an estimate of global intellectual ability four composites
Explanation:
Theoretical element “A” has four isotopes. Use the data in the table to calculate the average atomic mass of the unknown element A. All steps of the calculations must be shown for credit.
Isotope Atomic Mass Abundance
A - 49 49.022 amu 89.89%
A - 48 48.031 amu 7.01%
A - 47 48.007 amu 3.00%
A - 46 46.001 amu 0.10%
From the calculations, the average atomic mass of the element is 48.85.
What is the percentage abundance?The percentage abundance has to do with the amount of an isotope that is available in nature.
Since we have the following mass abundance;
A - 49 49.022 amu 89.89%
A - 48 48.031 amu 7.01%
A - 47 48.007 amu 3.00%
A - 46 46.001 amu 0.10%
The average atomic mass =
(0.8989 * 49.022) + (0.0701 * 48.031 ) + (0.03 * 48.007) + (0.001 * 46.001 )
= 44 + 3.4 + 1.4 + 0.05
= 48.85

Describe Cohesion and Surface tension, and explain how the structure of water is responsible for these properties.
Answer:
Cohesive forces are responsible for surface tension, a phenomenon that results in the tendency of a liquid’s surface to resist rupture when placed under tension or stress. Water molecules at the surface (at the water-air interface) will form
Adhesion and cohesion are water properties that affect every water molecule on Earth and also the interaction of water molecules with molecules of other substances.
Explanation:
Answer:
A water molecule, because of its shape, is a polar molecule. That is, it has one side that is positively charged and one side that is negatively charged. The molecule is made up of two hydrogen atoms and one oxygen atom. The bonds between the atoms are called covalent bonds, because the atoms share electrons.

how is an organism modified ?
Answer: genetic engineering
Explanation
Genetic engineering is the modification of an organism's phenotype by manipulating its genetic material. Some genetic engineering uses the principle of recombination. Recombination is the process through which a new gene is inserted into a bacterial DNA "The plasmid".

How would habitat fragmentation decrease biodiversity? support with evidence.
What ideas do you have to help eliminate habitat fragmentation?
What additional policies may be needed to increase the protection of endagered species?
Answer:PREVENTION AND MITIGATION OF FRAGMENTATION
Restoration: Converting once developed land to a natural state. Mitigation: Developers create or preserve lands of similar quality and size to that which they impact. Zoning: Adding wildlife and habitat conservation considerations to lo- cal development plans.
Explanation:
Answer:
For example the amazon rainforest is the most biodiverse place on the planet. With deforestation we are putting hundreds of species to extenction and causeing the biodiversity to drop. This causes the whole planet to suffer in many ways such as less oxegen more co2. Some ways we could help eliminate this is to restrict the number of trees to be able to be cut down. This would need to be done by the brazilian government to be able to enforce it.
