Answer:
NA+ gates open and flow into the Sarcolemma of the muscle fiber.
Answer:
Invertebrates have a very quick life cycle and die very easily, as a result, they evolve very quickly into many different types of animals. also, they are often very small and their ecosystems are subject to much quicker change than that of vertebrates, meaning that mutations in their genes become relevant more often. Many invertebrates span very large areas (sea animals span most of the oceans, insects span entire continents) and so they evolve to be different species in different places.
Or
They do not have bones, they live on water or land, they can have soft bodies or exoskeletons, and others are parasites.
Answer:
By cooling the heart, its need for oxygen is reduced. This allows surgeons to work on the heart for two to four hours without damaging the heart tissue.
Answer:
The volume of solution B will increase
Explanation:
In a non-penetrating solute, there is denial of a solute to cross the cell membrane.This implies that the solute will not be able to cross the cell membrane. So if the biological membrane is serving as a partition between a solution A containing 400 mosmol/L non-penetrating solute and a solution B containing 600 mosmol/L non-penetrating solute, The volume of solution B will increase.
Answer:
Mammals
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.
