Answer:
adaptations help the organsims to survive harsh weather, to avoid predators, to hide.
Answer:
between 75 mmHg and 100 mmHg
Explanation:
Answer:
1. In order to fix the bacterial to the slide;
<u>so that it will not be lost during the staining procedure.</u>
<u>so that false impression or result will not be given by the bacteria in water,</u>
<u>Distilled water is used to prevent contamination with impurities e,g metals ions and crystals</u>.
Explanation.
In smear preparation; the bacterial cells should also be well dispersed,so that they do not clumped together to form' big glob'.(large round masses) The later affect clear field view of the bacterial mophology, affected staining, and therefore gives inaccurate results,
Fixing to the slide also affects the morphology of bacterial cells, through shrinking in size, which can lead to loss of structural characteristics and extra-cellular matrixes,
Answer:
Decomposers recycle essential nutrients back into an ecosystem
Explanation:
An ecosystem works thanks to the constant transformation of energy. The role of the decomposers will be to transform energy into something useful in the ecosystem. For example, The bacteria which will rotten the apples that fall from a tree onto the ground are recycling or making available this energy for other organisms to use it. As part of this example, the essential nutrients of the apples will be available to be reabsorved by the roots of the apple tree thanks to the transformation of energy done by the bacteria in the apples.
Answer:
Acquired (or somatic) mutations occur at some time during a person's life and are present only in certain cells, not in every cell in the body. These changes can be caused by environmental factors such as ultraviolet radiation from the sun, or can occur if an error is made as DNA copies itself during cell division.
