Answer:
The correct answer is A) Biochemical test
Explanation:
In microbiology biochemical test is used to examine the metabolic activities performed by bacteria to identify that microorganism. So in biochemical test enzymatic reaction of cell is usually investigated because there is difference in enzymatic activity of different species of bacteria.
For example, catalase test that is used to differentiate between catalase-positive and catalase-negative bacteria is an example of biochemical test. Catalase-positive bacteria have the catalase enzyme that breaks hydrogen peroxide into water and oxygen which is confirmed by bubbles that appear on glass slide.
Catalase negative bacteria do not form bubbles when they are put in hydrogen peroxide which shows that they lack catalase enzyme. So the right answer is A.
Endocrine gland - a group of cells that secretes substances into the blood or directly into an organ.
Differ from exocrine glands, endocrine glands have no ducts and secrete products (hormones) directly into blood.
Hormone - a substance produced by cells that helps specific groups of cells to perform specific functions. It is a product of endocrine gland which functions as chemical messengers to stimulate other cells.
Duct – a channel or tube that conveys a substance. It is part of the exocrine glands (such as salivary glands) which makes contact with surface .
B. Segregation.
I have the same question and answered it and this is what it told me. I think it should be right.
The answer in the spaces provided is venture and calamity. The answer is venture because sky-diving is considered to be a an activity that seems to be adventurous and dangerous in which venture means while it also results into calamity because it causes distress in which she has injured herself.
<h2>Rhizoids absorb water and nutrients from the surrounding soil.
</h2>
Explanation:
Rhizoids are primitive root like structure in lower plants like bryophytes and sin fungi. Rhizoids are usually unicellular. However many plants exhibit multicellularity. Rhizoids functions as the roots in these plant,by absorbing water and nutrient from the surrounding soil. They may contain enzymes which helps in extracellular digestion in orgsnidm which have saprotrophic mode of nutrition.Rhizoids provide a little anchorage to the substratum.
