Which phenomena release CO2 into the atmosphere?
matrenka [14]
Hello to answer your question.

A is correct
 But more likely forest fires would be the culprit because the trees produce O2
 so when the are burnt, it would be like everybody o this earth breathed out at   once causing CO2 to be released in to the atmostphere in a big burst

1. Introduction:
inna [77]

Answer:

1. Introduction

     a. The<em> Tiktaalik </em>is a fossil that<em> </em>existed about 12 million years before the first tetrapods.

    b. The items homeostatic mechanisms show are continuity and change.

2. Continuity

       a. Our Excretory system is the system responsible for the discharging of waste products from the body.

Explanation:

1 a. Tiktaalik fossil (<em>Tiktaalik roseae</em>), also known as the "fishapod," is a 375 million year old fish fossil  discovered in 2004 in the Canadian Arctic. The fossil displays a mixture of fish and amphibian traits (i.e the pioneer tetrapods). Those tetrapod features in the <em>Tiktaalik</em> marks the earliest appearance of these features in fossil record.

Importance: The discovery of the <em>Tiktaalik</em> fossil explains  a crucial point in the history of life on Earth: i.e it sheds light on when the very first fish ventured out of the water onto land.

b. Continuity in homeostasis implies common ancestry or homology. For example the excretory system in flatworms, earthworms and vertebrates basically serves the same function, and has remained unchanged (save for a few tweaks), over the last few million years.

Change implies changes in the environment which causes changes in homeostatic mechanisms. For example the transition of aquatic animals from water to land which necessitates changes in their respiratory mechanisms.

2. Continuity

a. The excretory system is the system of an organism's body that is responsible for the function of excretion, the process of eliminating bodily wastes produced by homeostasis.

The mechanisms of homeostasis are body temperature, body fluid composition, blood sugar, gas concentrations, and blood pressure.

The organs that are involved in this process of waste elimination are the sweat glands, the liver, the lungs and the kidneys.

The metamorphosis of a tadpole to an adult frog involves a thorough reconstruction of the animal's body. All of the structural a
alexira [117]

The metamorphosis of a tadpole to an adult frog involves a thorough reconstruction of the animal's body. Positive feedback regulation would ensure that the animal completed its transformation.

Positive feedback regulation of prothoracic hormone secretion by ecdysteroids is the mechanism that determines the timing of metamorphosis.

Metamorphosis is the biological process by which an animal develops physically, including birth and hatching, and which involves marked and relatively rapid changes in an animal's body structure due to cell growth and differentiation.

Some insects, fish, amphibians, mollusks, crustaceans, cnidarians, echinoderms, and tunicates undergo metamorphosis, often with changes in diet and behavior.

In case of frogs, and toads, forelimbs are formed under the gill pouch, and the hind limbs are visible after a few days. This is usually followed by a longer phase in which the tadpoles are fed a vegetarian diet.

Tadpoles use a relatively long spiral intestine to digest this food. Recent studies suggest that tadpoles do not have a balanced homeostatic feedback control system until early stages of metamorphosis.

At this point, their long intestine shortens and they prefer insects.
