In general, why might ecologists be concerned when new invasive species arrive in an ecosystem?

7 0

Invasive species might overpopulate in the area which might cause the native species to be threatened, have to leave, or decrease in amount.

Which organism is most specialized?<br> a) bacteria<br> b) ant<br> c)cat<br> d)unicellular algae

Kryger [21]

The correct option is C, CAT.
Cat is an eukaryote and it possesses eukaryotic cells. The cells that are found in cat are specialized in that each type of cell perform only specific functions. The cells that are found in its digestive tract perform functions that are different from those found in its circulatory system.

How would your result have been affectted if you had stored your beakers uncovered for one week in the student cabinet?

musickatia [10]

<h2>Answer:</h2>

While performing any kind of experiment in lab one must be very careful about contamination from other resources.

If you had stored the beaker uncovered for a week, there are 100% chances that your sample will get contaminated either from airborne bacteria in the atmosphere of the lab, other bacteria's from surroundings, or viruses or fungi or any other kind of microbes. If beaker is open there also dust particles that penetrate in it.

So, It is necessary that you should cover your beaker properly with plastic or glass lid or aluminum foil etc while incubation for the smooth results of your experiment.

Instructions: As you respond to Part A and Part B, follow the directions below.

The mitochondria is the site of the aerobic respiration in the eukaryotic organism. The mitochondria uses the glucose and the oxygen molecules to form the carbon dioxide, water and ATP (adenosine triphosphate) molecule.

The equation for the aerobic respiration is given below:

$C_{6}H_{12}O_{6}+6O_{2}\rightarrow 6CO_{2} + 6H_{2}O$

Glucose + oxygen $\rightarrow$ carbon dioxide + water

All the reaction takes place in the mitochondria, Hence, the givenb lanks can be filled as follows:

1. glucose

2. oxygen

3. carbon dioxide

4. water

5. ATP

The process shown in the figure is aerobic respiration. In the given figure, the mitochondria is shown, the mitochondria is the site of aerobic respiration. The mitochondria obtain the glucose and the oxygen molecule present in the cytoplasm of the cell. The complete aerobic respiration takes place in three steps glycolysis, Kreb cycle and electron transport. In the glycolysis, the glucose is converted into pyruvate. In the Krebs cycle, the pyruvate is oxidised in acetyl-CoA, which undergoes a sequence of reaction giving out ATP from ADP. In the electron transport chain, the NADH as well as succinate, which is formed in the citric acid cycle or Krebs cycle are oxidized, which provides the energy to power ATP synthase (the enzyme involved in the creation of storage of ATP).
