L.A student was told that a drawing of a bacterial cell had been magnified 30 000 times. The length of the drawing was 45 mm. What was the actual length of the bacterium?

Answers

Answer 1

Answer:

1.5 microns

Explanation:

It is given that the drawing of the bacterial cell is magnified by 30,000 times.

The size of the drawing of the bacterial cell is 45 mm

                                                                           = [tex]$45 \times 10^{-3} \ m$[/tex]

Now size of the drawing = actual length of the drawing x magnification  

Actual length of the bacterium is given by

    = [tex]$\frac{45 \times 10^{-3}} {30000}$[/tex]

    [tex]$= \frac{45 \times 10^{-3}} {3 \times 10^4}$[/tex]

   [tex]$= 1.5 \times 10^{-6} \ m$[/tex]

or 1.5 microns

Climate change (an abiotic factor) has slowly decreased habitat for the arctic seals. Predict how a reduction in habitat could change the capture efficiency of the killer whales. How would this affect the carrying capacities for both the whales and the seals?

If another source of prey were available to the whales, what changes in population size would you expect for the seals and the whales?

What are the limitations of the population dynamics lab? Is the lab activity a realistic representation of an arctic marine ecosystem?

Answers

Answer

#1. A reduction in habitat for arctic seals will reduce the population of arctic seals. This will reduce the capture efficiency for killer whales preying on arctic seals because there will be fewer to capture. A reduction in habitat for arctic seals will lower the carrying capacity for arctic seals because there is less habitat. A reduction in arctic seals, the food for killer whales, will reduce the carrying capacity for killer whales, unless there is a substitute source of food.

#2. If there is another source of food for killer whales, the population of killer whales will probably remain the same, if they were at their carrying capacity and their habitat remains the same. If there is another source of food for killer whales, the population of arctic seals will still decrease, because the habitat for arctic seals has decreased, and habitat is independent of predator population.

#3. There are many limitations on any simulation. The computer only uses the parameters in the program, so changes in ocean temperature, weather patterns, salinity changes, food supply, habitat, interaction with other species and presence of plants and zooplankton are not considered. All of those can change and change the results.

Explanation:

I am a man of god

A reduction in habitat for arctic seals will reduce the population of arctic seals. This will reduce the capture efficiency for killer whales preying on arctic seals because there will be fewer to capture.

What is climate change?

A reduction in habitat for arctic seals will lower the carrying capacity for arctic seals because there is less habitat. A reduction in arctic seals, the food for killer whales, will reduce the carrying capacity for killer whales, unless there is a substitute source of food.

BLOOD:

The blood is a crucial part of the circulatory system. It functions majorly as a carrier tissue in the body. The blood carries substances like hormones, glucose, carbon dioxide, oxygen etc. from one location to the other.

The blood is, however, a tissue made up of different cells and components namely: erythrocytes, leucocytes, plasma, platelets.

The plasma component of the blood is its liquid part and makes up majority of blood's volume. The plasma is the medium in which most substances in the body dissolves and transported.

Therefore, the part of the blood that transports insulin to its target organs is plasma.

Answers

Answer:

Inputs: carbon dioxide (CO2) and water (H2O)

Output: Sugar (C6H12O6) and oxygen

- Roots take in water

- Leaves take in carbondioxide

Explanation:

Photosynthesis is a unique metabolic process undergone by only set of organisms called AUTOTROPHS. Autotrophs are capable of synthesizing their own food by capturing light energy (from sun) and using it to make food (sugars).

This photosynthetic process requires certain substances called INPUTS, which are basically carbon dioxide (CO2) and water (H2O) and give out products called OUTPUTS, which are sugars and oxygen gas.

- The CO2 input is taken in by the plant via the stomata on its leaves while the water (H2O) is absorbed by the roots of the plant.
