Answer:
Active transport requires cellular energy to achieve this movement. There are two types of active transport: primary active transport that uses adenosine triphosphate (ATP), and secondary active transport that uses an electrochemical gradient.
4 Types:
1. P-type ATPase: sodium potassium pump, calcium pump, proton pump
2. F-ATPase: mitochondrial ATP synthase, chloroplast ATP synthase
3. V-ATPase: vacuolar ATPase
4. ABC (ATP binding cassette) transporter: MDR, CFTR, etc.
Explanation:
Stereoscope. It's like a less powerful microscope
Answer:
Mosses or lichens.
Explanation:
Mosses or lichens are the group of species have great impact on the long term dynamics of succession if they develop resistance against fire events because these species can used the ashes of other plants as a nutrients for their growth and development. These group of species spread at a higher rate which covers most of the area of the forest and become a dominant species in the forest. Due to the presence of these species, the organisms who feed on these species comes to these forest and slowly the diversity of the forest is attained.
Answer:
The skin consists of two layers: the epidermis and the dermis. Beneath the dermis lies the hypodermis or subcutaneous fatty tissue. The skin has three main functions: protection, regulation and sensation. Wounding affects all the functions of the skin.
Explanation:
A DNA molecule is made up of nucleotides.Each nucleotide is made up of a nitrogen base, a sugar molecule and a phosphate group. There are 4 nitrogen bases such as adenine and guanine known as purines, thine and cytosine are known as pyramidine. These nitrogenous base are arranged in a sequence attached to each other by hydrogen bonding into anti-parallel strands. Therefore, the structure of DNA is termed as the double helical model.
