Answer:
The simplest definition of an ecosystem is that it is a community or group of living organisms that live in and interact with each other in a specific environment.
Answer:
mamals and birds
Explanation:
The Organs which perform same function and looks but they are different in their structure from each other are called as analogous organs.
Organs are the structures that made up of two or more tissues organized to carry out a particular function.
An organ or bone that appears in different animals with same function is called homologous structure.
Homologous organs have similar origin n basic structure but perform different functions in different organisms. Analogous organs are different in basic structure but perform same functions.
Different animals have bones that appear very similar in form or function and seem to be related.
Examples
The arm of a human, the wing of a bird or a bat, the leg of a dog and the flipper of a dolphin or whale are homologous structures. They are different and have a different purpose, but they are similar sharing common traits.
The forelimbs of all mammals have the same basic bone structure.The structures are similar because they evolved to do the same job. For example, the wings of bats and birds.
The best and most correct answer among the choices provided by the question is the third choice. A universal system of measurement should be used in collecting data. I hope my answer has come to your help. God bless and have a nice day ahead!
Answer:
The Atomic number is 17 and Mass number is 35
Explanation:
<h3><u>Given</u>;</h3>
- No. of protons = 17
- No. of neutrons = 18
<h3>
<u>To</u><u> Find</u>;</h3>
So, For Atomic number
Atomic Number = No. of protons = No. of electrons = 17 (Which is Chlorine {Cl} )
Now, For Mass number
Mass number = No. of protons + No. of neutrons
Mass number = 17 + 18 = 35
Thus, The Atomic number is 17 and Mass number is 35
