1. = <u>Surface</u><u> </u><u>area</u>

Volume

= <u>(</u><u>2</u><u> </u><u>*</u><u> </u><u>1</u><u>)</u><u> </u><u>m</u><u>²</u>

(1*2*0.5) m³

= 2 m-1 (the negative 1 is an exponent).

2. for elephant,

= S/V

= 25/10

= 2.5 m-1

for pigeon,

= S/V

= 0.5/0.05

= 10 m-1

Pigeon has the larger surface area to volume ratio.

3.

= S/V

= <u>(</u><u>4</u><u>0</u><u> </u><u>*</u><u> </u><u>3</u><u>0</u><u>)</u><u>m</u><u>²</u><u> </u><u> </u><u> </u><u> </u>

(40*30*40) m³

= 0.025 m-1

4.

= S/V

= <u>(</u><u>4</u><u> </u><u>*</u><u> </u><u>6</u><u>)</u><u> </u><u>c</u><u>m</u><u>²</u>

(4*6*5) cm³

= 0.2 m-1

hope you understand. All the best!

58:57 What would most likely happen to life on Earth if the carbon cycle stopped? Life would continue unchanged. Life would ceas
Naddik [55]

Answer: Life would cease to exist.

Explanation:

The carbon elements is one of the most important elements in the compound that make up living organisms. It is found: in the remains of living organisms; as fossil fuels such as coal, coke and natural gas; as inorganic salts such as carbonates; in water bodies and as gas carbondioxide which makes up 0.03% of air.

Carbon is continuously being circulated in the atmosphere through a process called the CARBON CYCLE. This involves the removal and addition of carbon to the carbondioxide in the atmosphere.

Life would indeed cease to exist if this carbon cycle stops due to the importance of carbon to functioning of living organisms. Important processes which bring about the recycling of carbon between living ( biotic) and non living (abiotic) components of an ecosystem are:

--> photosynthesis: the process used by green plants to remove carbon through carbondioxide from the atmosphere for manufacturing of their food.

--> respiration: animals respire to break down sugar leading to liberation of carbondioxide and water as wastes

--> and decay: decomposers feeds on remains and waste to bring about decay, thus complex carbon compounds are broken down to set free carbondioxide which returns to the atmosphere.

All the above processes are carried out by living organisms to maintain a functioning ecosystem by enabling a linear flow of energy through it.

Pavlova-9 [17]

These secondary compounds are primarily adaptations that is inhibit herbivory.

Option D is correct.

What is meant by herbivory?

Herbivory may be a form of consumption in which an organism principally eats autotrophs such as plants, algae and photosynthesizing bacteria. More generally, organisms that prey on autotrophs in general are known as primary consumers. Herbivory is typically limited to animals that eat plants

What is the herbivory effect?

Herbivory can affect the expansion form of plants by terminating shoot growth and initiating branching and by affecting shoot-to-root ratios. Changes in survival, productivity, and growth of individual plant species affect vegetation structure and community dynasty.

<h3>Why is herbivory important?</h3>

Herbivory can have substantial impacts on habitat health, the structure and variety of plant and soil invertebrate communities and the productivity of economically important crops. The positive impact of herbivory is widely debated within the scientific literature.

erica [24]
<span>The answer is C.glycolysis ® Krebs cycle ® electron transport chain. There are 3 stages of cellular respiration: 1. glycolysis when glucose is broken down to pyruvate in the cytoplasm; 2. Krebs cycle when Acetyl CoA and oxaloacetate form a 6 C-atoms compound; 3. Electron transport chain when hydrogen molecules removed through previous stages are pumped to the chain and energy is produced.</span>
