I need help with the Collision Theory Portfolio Worksheet plzzzzz its due today i really need help.

Biology
1 answer:
guapka [62]3 years ago
3 0

The collision theory in chemistry is used for the prediction of the rates of the chemical reactions, it is mainly used for the calculation of the rate of the chemical reactions occurring in the gaseous state.

The main assumption of this theory is reacting substance (atom or molecule) must come and collide to react and form a product. It was proposed by Max Trautz in the year 1916.

Be able to describe the structures and functions of these systems and how they work together:
san4es73 [151]

The nervous system: In biology, the nervous system is a highly complex part of an animal that coordinates its actions and sensory information by transmitting signals to and from different parts of its body.

The circulatory system: The circulatory system is made up of blood vessels that carry blood away from and towards the heart. Arteries carry blood away from the heart and veins carry blood back to the heart. The circulatory system carries oxygen, nutrients, and hormones to cells, and removes waste products, like carbon dioxide.

The respiratory system: The respiratory system is a biological system consisting of specific organs and structures used for gas exchange in animals and plants. The anatomy and physiology that make this happen varies greatly, depending on the size of the organism, the environment in which it lives and its evolutionary history.

The muscular system: The muscular system is an organ system consisting of skeletal, smooth and cardiac muscles. It permits movement of the body, maintains posture and circulates blood throughout the body. The muscular systems in vertebrates are controlled through the nervous system although some muscles can be completely autonomous.

Scientists have found that extracellular matrix components may induce specific gene expression in embryonic tissues such as the
serg [7]

Scientists have found that extracellular matrix component may induce specific gene expression in the embryonic tissues such as the liver and testes. For this to happen, there must be a direct communication between the extracellular matrix and the developing cells. The Integrins of transmembrane protein would most likely be involved in this kind of induction.

Integrins are the main principal receptors used by the cells of  animal to bind to the matrix of extracellular. They are heterodimers and they function as transmembrane linkers between the actin cytoskeleton and the extracellular matrix. A cell can regulate the sticky activity of its integrins from within.

A major disturbance that the ecosystem was able to recover completely from. ____________________________________________________
icang [17]

Complete Question:

I made the grass diseased. This caused all of the populations above it (rabbit, snake, and hawk) to rapidly decrease over the 12 month period

(a) A major disturbance that the ecosystem was able to recover completely from __________

(b) A major disturbance that caused the ecosystem to stabilize at a new equilibrium ____________

(c) A major disturbance that caused the ecosystem to completely collapse __________

ANSWER:

(a) reducing the hawks to nearly zero

(b) removing all of the hawks

(c) removing all the diseased.

Explanation:

(a) reducing the hawks to nearly zero will cause low depletion of the producer (plants) and this will allow the plant to grow (without visible depletion) over a period of time.

(b) for the ecosystem to stabilize at a new equilibrium, the tertiary consumer (hawks) will be totally removed from the ecosystem. Since there's no tertiary consumer to checkmate the density of other components of the food chain, it will make it form a balanced ecosystem.

(c) for ecosystem to collapse, it's important to note that the removal of the producer (plants) will be bring about the loss of the ecosystem. Since, their is no manufacturer of food, the primary consumer (rabbit) in the food chain will be starved and overtime the rabbits will be wiped out and this will caused the loss of secondary and tertiary consumer in the long run.

3. C but i'm not sure

4. </span>The initial 2 aren't right. What's more, the third one is just valid if the therapeutic issue is y-connected so it's not ALWAYS. So that abandons you the last one, which bodes well on the grounds that the tyke gets qualities from the father too which impact it's wellbeing.

5. A but i'm not sure

The Susquehanna River, which runs through the states of New York, Pennsylvania, an Maryland , received the title- America's most
Lina20 [59]

This  produces several negative effects on the biodiversity of the river ecosystem.

<u>Explanation:</u>

The Susquehanna river is polluted by the excess release of nutrients like phosphorous and nitrogen from agricultural land and sewage treatment plants. This can adversely affect the health of the river. The excess of nutrients will accelerate the growth of algae in the river.

The dead algae that settle at the bottom of the river decay by consuming the oxygen present in the river. This will reduce the amount of dissolved oxygen in the river and affect aquatic life.

Thick algal growth partially prevents the penetration of sunlight into the water and this affects the growth of submerged plants which are food to the fish.
