<span>Protein channels are needed to transport substances because it accelerates the transport process. Very few substances enter or leave cells without being attached to a transport protein. Different types of substances require different types of proteins to transport them. Protein channels transport water or ions downwards and ATP-powered pumps transport molecules or ions upwards. ATP generates energy to transport the molecules upwards. Gravity is used to transport the water molecules downwards. So, in a nutshell, if substances need to be transported from the top of the body downward, the force of gravity is used to transport the substances down. If substances need to be transported upwards, ATP, a coenzyme, is used to generate energy to transport the substance upwards</span>
Answer:
pressure of the gas inside the lungs will be =1.35 atm
Explanation:
so for calculation of pressure of gas we will use the formula
(remember to convert *C to kelvin)
PV₁/T₁ = P₂V₂/T₂ As we know that Temperature = 310.5 k =37 degree
so for pressure P₂
P₂=P₁V₁T₂/T₁V₂
= ((1.00atm)(2.20L)(310.15K))/ ((298.15K) (1.70L)
=1.35 atm
(remember to convert *C to kelvin)
Answer:
cell division
Explanation:
It starts with a cell called the mother cell, divides into two cells called daughter cells. If they have the same number of chromosomes it is called mitosis. As in there are two different stages of cell division. Where as meiosis, they don't have the same amount of chromosomes.
Answer:
Option A, The animal can only live in Australia
Explanation:
At present the Koala are found in several states of Australia such as
a) Queensland
b) NSW
c) Victoria
d) South Australia
Though the Koala is found on the eucalyptus trees of the temperate rain forest , they are only found in Australian geographies . There are several other place on planet earth where there is rainforest with eucalyptus trees and temperate climate, even though the Koalas are limited to Australia.
Hence Option A is correct.
