Answer:
<em><u>H1: false, the observations of the molecules do not support the hypothesis...</u></em>
Explanation:
The cell membrane is comprised of a phospholipid bilayer, proteins, and cholesterol. These components help the membrane to maintain its selective permeability and concentration of solutes and water.
The lipid molecules have polar hydrophilic heads and hydrophobic tails. These only readily allow for the movement of small non polar molecules. Other substances, like charged ions and large molecules require transport proteins to move in and out of the cell. Hypothesis: H+ is small and should be able to move freely through the membrane, While glucose is large and cannot move freely
- Observing H+, despite being very small these cannot easily pass through the membrane. They require transport proteins called channels for their free movement or passive movement across the membrane.
- For glucose, these molecules pass through specialized channels in facilitated diffusion. They move down their concentration gradient into the cell. To move out of the cell against its concentration gradient glucose requires ATP for active transport.
- Cortisol, is a large steroid hormone, taken into the cell by simple diffusion across the lipid membrane, down its concentration gradient.
Answer:
Adaption radiation
Explanation:
This process explains how organisms transform rapidly due to the changes within their environment. When a change occurs it created new challenges, new resources are available, as well open up to new environmental niches.
The statement about secondary production that is false is option c. Generally, an individual's production efficiency will decline as the C:N ratio of its food increases.
<h3>When is productivity and efficiency present?</h3>
Productive efficiency states that it is not possible to generate more of one good without producing less of another good given the inputs and technology at hand.
Note that Production efficiency is a word used in economics to describe the point at which an economy or other entity can no longer produce more of one good without reducing the level of production of a different one.
Hence, It's more important to focus on the caliber of your job than just the pace. Therefore, you have achieved improved production efficiency if your company increased its output from 1,000 bags to 1,500 bags of coffee while generating less waste, spending less money, and utilizing fewer resources.
