Abiotic factors that could affect the stability of an ecosystem could include

You are invited to participate in a debate about the concept of evolution. Construct an opening statement supporting evolution,

Masja [62]

When talking about evolution, a good example is bacterial resistance to antibiotics.

We start with a bacteria colony, and in contact with antibiotics, most of them die.

Some of them in the colony do not die and took that antibiotic to create a mutation of its DNA to be resistance to that.

They evolved survive that antibiotic.

Column A Column B a. Astrocyte b. Axon c. Collateral d. Dendrite e. Myelin f. Neurilemma g. Neurofibrils h. Nissl bodies (chroma

xenn [34]

Answer:

1.) neurilemma (option f)

2.) nissil bodies (chromatiophillic substance)

3.) neurofibrilis ( option g)

4.) myelin ( option e)

5.) dendrite ( option d)

6.) collateral ( option c)

7.) astrocytes (option a)

8.) axon ( option b)

9.) Unipolar neuron (option i)

Explanation:

The neurological terms described above are different parts of a nerve cell or neurones. The nerve cells are the basic Structural units of the nervous system. They are highly specialised for transmitting electric impulses. They can also be grouped according to the number of processes they possess, for example, the UNIPOLAR NEURONS( those with one process only). Each neuron, however, is composed of the same basic parts which include:

--> The CELL BODY: they may be angular or oval in shape with a large nucleus and dense granulated cytoplasm. In the cytoplasm, rough Endoplasmic reticulum which contains CHROMATIOPHILLIC SUBSTANCE (nissil bodies) and Golgi apparatus are also seen.Network of threadlike structures known as neurofibrilis are also seen within the cell body and extending into axon.

--> DENDRONS: these are one or more extensions which branches to form many fine dendrites. The DENDRONS carry nerve impulses( action potential) that their dendrites receive to the cell body.

--> AXON: this is a long process which branches at it's free end to end in synaptic knobs. It carries electric impulses away from the cell body. Most times, a substance of Schwann cell known as MYELIN SHEATH which is composed of lipoprotein insulates axons and increases impulse speed.

Callie did a lab during which she investigated the difference in cellular respiration rates between two different types of corn:

lisabon 2012 [21]

Answer:

I might be wrong but im guessing 600

Explanation:

Since there is one molecule of glucose used per 6 molecules of carbon dioxide released, if you have 100 molecules of glucose, then you multiply the carbon dioxide by 100 which is 600. Thats what I would say but I might be wrong.

Carbohydrates are the primary source of energy for the human body. If your body lacks enzymes that break down carbohydrates, it

SVEN [57.7K]

Ambitious

If your body lacks enzymes that break down

carbohydrates, it would be unable to get sugar molecules for energy production.

If you lacked the enzyme to digest proteins, you may not absorb enough amino

acids.

The digestive system in our body changes

carbohydrates into glucose; also known as blood sugar to be use as an important

source of energy. Meanwhile, amino acids are organic compounds that combine to

form proteins, which are the building blocks of life.

if you wanted to test red blood cells for their ability to complete glycolysis, what compound would you try to detect

Artemon [7]

Answer:

Pyruvate

Explanation:

Glycolysis refers to the pathway through glucose is oxidized to pyruvate.

In glycolysis, a molecule of glucose passes through ten enzyme catalyzed steps to yield two molecules of pyruvate.

Step 1: Glucose is phosphorylated to form glucose-6-phosphate

Step 2: Glucose-6-phosphate is converted to fructose-6-phosphate

Step 3: Fructose-6-phosphate is further phosphorylated to form fructose-1,6-bisphosphate

Step 4: Fructose-1,6-bisphosphate is cleaved into glyceraldehyde-3-phosphate and dihydroxyacetone phosphate

Step 5: Dihydroxyacetone phosphate is converted to another molecule of glyceraldehyde-3-phosphate.

Step 6: Two molecules of Glyceraldehyde-3-phosphate are converted to two molecules of 1,3-bisphosphoglycerate

Step 7: Two molecules of 1,3-bisphosphoglycerate are converted to 3-phosphoglycerate

Step 8: Two molecules of 3-phosphoglycerate are converted to two molecules of 2-phosphoglycerate

Step 9: Two molecules of 2-phosphoglycerate are converted to two molecules of phosphoenolpyruvate

Step 10: Two molecules of phosphoenolpyruvate are converted to two molecules of pyruvate, the end-product of glycolysis.

Therefore, the presence of pyruvate molecules in red blood cells can be used to test for their ability to complete glycolysis
