caudal fin lr sometimes is called tail fin
Organisms that originated in a certain geographic region and can only be found in that region are said to be endemic.
Explanation:
Endemic organisms are taxonomic species (plants and animals) which originates and distributed only in specific geographic regions. This state of evolution is called endemism.
They are said to be native or indigenous to that particular region which can be an ecological habitat, an entire nation, an island, a mountain range etc. Certain parts are known for majority of their species being endemic like St. Helen Island, New Caledonia Island, Hawaiian Islands, Southern regions of Africa, and Australia.
The species becomes endemic to a particular region because of the presence of certain bio-geographical environmental qualities of that habitat which are favorable to that species.
When these conditions become unfavorable, then species becomes restricted leading to endangerment or extinction of the species.
Examples:
- Kangaroo - Australia
- Nilgiri Tahr, - Nilgiri Hills, India
- The Redwood trees of West Coast of the USA
- Plants like kalo, sumac of Hawaii
Answer:
DIFFUSION
Explanation:
Water, carbon dioxide, and oxygen are among the few simple molecules that can cross the cell membrane by diffusion (or a type of diffusion known as osmosis ). Diffusion is one principle method of movement of substances within cells, as well as the method for essential small molecules to cross the cell membrane.
<h3><u>Answer;</u></h3>
C) P and Q have similar binding properties
<h3><u>Explanation;</u></h3>
- <u><em>Enzymes are biological catalysts that speeds up chemical reactions. Substrates are substances that are acted on by an enzyme to form a product.</em></u>
- <u><em>An enzyme catalyzed reaction occurs when the substrate binds to the active site of an enzyme to form and enzyme-substrate complex. </em></u>
- <em><u>Substrate P and Q are structurally similar which means they are in a position of binding and fitting in the active site of an enzyme. The strong structural similarity means that the binding properties of these two different substrates may be similar. </u></em>
- <em><u>Formation of similar products or results when acted upon by an enzyme mean they are similar in terms of their binding properties, and thus the production of similar product.</u></em>
Answer:
B- lysosomes
Explanation:
Hydrolotic enzymes are enzymes that break down fat, lipids, etc... which help aid lysosomes in there job since the lysosomes break down waste products.
