The purpose of chitinous cuticle serve in an earthworm is to prevent the worm from dehydration  and also provides protection. Cuticle is a thin, non-cellular coating on the surface that prevents dehydration and provides protection. The cuticle also allow oxygen to pass into the coelomic fluid and blood of the worm. It protects the worm from drying out and also protects the epidermis from abrasion from soil particles.

The Yellowstone River ecosystem can support 2,300 bald eagles. This is an example of<u> temperate- zone ecosystems</u>

Explanation:

Yellowstone National Park is a natural  paradise with over 70 species of birds,which  include  trumpeter swans, sandhill cranes, loons, peregrine falcons, osprey and bald eagles

The Greater Yellowstone Ecosystem, with Yellowstone at its core, is one of the largest nearly intact temperate- zone ecosystems on Earth. It has an area of 12–22 million acres; 18,750– 34,375 square miles

<u>Temperate ecosystems are the ecosystem that are characterized by the  seasonality in temperature, with cooler winters and warmer summers, and also  show various  seasonality in precipitation patterns, resulting from seasonal changes in the orientation of Earth's axis relative to the sun.</u>

<u></u>

What is the final acceptor of electrons in the electron transport chain?
aksik [14]

The final acceptor of electrons in the electron transport chain is "C" , that is oxygen.

The electron transport  chain is composed of a series of electron carriers that operate together to transfer electrons from donors, like NADH and FADH2, to acceptors such as O2.

The electrons flow from carriers with more negative reduction potentials to those with more positive potentials and eventually combine with O2 and H+ to form water. 

The difference in reduction potentials between oxygen and NADH is large, about 1.14 volts and makes possible the release of a great deal of energy.

What are 2 observations that lamarck makes and what is the inference he makes based on these observations?
GaryK [48]

The main 2 observation which Lamarck made is:

<u>1. </u><u>Use and Disuse of Organ</u>

<u>2.</u><u> Inheritance of Acquired Characters.</u>

The Use and Disuse of Organ states that, only those character will last longer or pass on to next generation which are getting in use day by day. And, the organ will vanish if it not in use. Like, Tail in Human.

Inheritance of Acquired Characters, a theory that suggests physiological changes that an organism acquires throughout the course of its existence might be passed on to children. It's often referred to as the theory of adaptation or Lamarckism, after French biologist Jean-Baptiste Lamarck's theory of evolution.
