Answer:
Small, nonpolar molecules (ex: oxygen and carbon dioxide) can pass through the lipid bilayer and do so by squeezing through the phospholipid bilayers. They don't need proteins for transport and can diffuse across quickly.
Explanation:
The channel proteins act like doors through the cell membrane.
They allow large polar molecules to move in and out of the cell.
The process is called passive diffusion or passive transport, because it does not need energy.
Sometimes the protein changes shape to help the polar molecules move through the channel.
It often uses a gated pore mechanism, in which the channel is never completely open.
Answer:
False. SQRW does not increase reading speed.
Explanation:
SQRW stands for Survey, Question, Reading and Writing. SQRW is a four-step strategy for reading and note-taking from a chapter in a material to be read. The SQRW strategy does not make for faster reading abilities, rather it makes for a more efficient reading ability The four steps include:
- Survey: This involves taking a quick broad glance at the chapter to be read, including the title, introduction, headings, images, summary or conclusion. It helps one to recall previous knowledge on the topic and prepares one for new learning.
- Question: As one reads, questions are formed in the mind, this helps the reader to stay focused, and gives the reader a purpose for the reading. It is helpful to turn each heading into a question
- Read: The information following each heading is read, to find out the answers to the questions formed earlier for each head
- Write: Each question and its answer are written down and reread to be sure that each answer is legible and contains all the important information needed to answer the question.
Answer:
this doesnt make sense please look over your question and correct the wording
Answer:
Dichotomous keys typically stress identifying species by their scientific name, as each individual species has a unique scientific name. Dichotomous are very useful because they allow non-expert users to identify organisms by directing them to look at the known, important organisms.
