autotrophic is like plants, they can make their own food.
saprophytic means is called on an organism, especially fungi, that feeds on dead material only.
Answer:
When the required direction of transport is opposed to concentration levels, a cell <u>will </u> expend energy to force<u> ions</u> across its membrane.
Explanation:
If the concentration gradient is opposite to the direction of transport of minerals, then the cell will use energy to transport mineral ions from a lower concentration to a higher concentration. The most common process through which this happens is termed as the active transport.
The process of active transport is opposite to passive transport. In passive transport, molecules move from a higher concentration to a lower concentration.
Answer:
double helix, which is made up of a nitrogenous base, a five-carbon sugar (deoxyribose), and a phosphate group. There are four nitrogenous bases in DNA, two purines (adenine and guanine) and two pyrimidines (cytosine and thymine).
Explanation:
A common way that humans pollute water is through the addition of nutrients (fertilizers and sewage) to water as nonpoint source pollution. These added materials are full of nitrogen and phosphorus, two nutrients that encourage the growth of aquatic producers, such as algae.
The white blood cells are responsible for engulfing foreign material such as debris and microorganisms in the blood and other tissues. There are types of white blood cells that are specialized in phagocytosis, these are the: (1) neutrophils and the (2) macrophages.
<em>Neutrophils are more abundant in acute inflammation and marcophages are more significant in chronic inflammation.</em>
