Answer:

reason scientists classify living things is to understand the relationships between different organisms

Taxonomy . scientists organize the Living World using a process called taxonomy which is the sign of classify organisms based on shared structures ,functions , in relationships to other organisms

Calculate the actual size of the organelle (A to B). Show all your workings in microns (um). <br>

fredd [130]

To measure the diameter of a organelle with a scale line of 1 µm.

Measure the length of the scale line on the micrograph in mm, e.g. 1 µm = 17mm.
Measure the diameter of the organelle in millimetres, e.g. = 60mm.
True diameter of organelle.

<h3>How do you find the actual size of an organelle?</h3>

To calculate the actual size of a magnified specimen, the equation is simply Mixed6 :

Actual = Image size (with ruler) ÷ Magnification.

Thus, this is how we can measure the size of an organelle.

Suppose that at a given point along a capillary, the following forces exist: Capillary hydrostatic pressure (HPc) = 30 mmHg Inte

Ainat [17]

Answer:

Suppose that at a given point along a capillary, the following forces exist: Capillary hydrostatic pressure (HPc) = 30 mmHg Interstitial fluid hydrostatic pressure (HPif) = 0 mmHg Capillary colloid osmotic pressure (OPc) = 25 mmHg Interstitial fluid colloid osmotic pressure (OPif) = 2 mmHg. The net filtration pressure at this point in the capillary is <u>7mmHg.</u>

Explanation:

Data:

Capillary hydrostatic pressure (HPc) = 30 mmHg

Interstitial fluid hydrostatic pressure (HPif) = 0 mmHg

Capillary colloid osmotic pressure (OPc) = 25 mmHg

Interstitial fluid colloid osmotic pressure (OPif) = 2 mmHg

Formula Applied :

Net filtration pressure= hydrostatic pressure gradient - Oncotic pressure gradient

Hydrostatic pressure gradient = Capillary hydrostatic pressure - Interstitial hydrostatic pressure = 30mmHg - 0 mmHg = 30 mmHg

Oncotic pressure gradient = Capillary colloid osmotic pressure - Interstitial fluid colloid osmotic pressure =25 - 2 = 23 mmHg

Net filtration pressure= hydrostatic pressure gradient - Oncotic pressure gradient = 30 mmHg - 23 mmHg = 7 mmHg.

Hence, The net filtration pressure at this point in the capillary is <u>7mmHg.</u>

Living things are composed only of organic elements, whereas nonliving things are made up of inorganic elementsa. Trueb. False

Scilla [17]

Answer: option B) Statement is false

Explanation:

Living things are NOT composed only of organic elements. Organic elements refers to compounds of Carbon, whereas living things such as Vertebrates (man, shark, lion etc) possess bones, teeth with INORGANIC components like phosphorus, magnesium, calcium.

Also, nonliving things are NOT made up of only inorganic elements. A good example is the air we breathe, it is non-living, yet contains carbon in the form of Carbiondioxide.
