The unique - tertiary structure of the enzyme is what makes it unique - this in combination with the receptors at the active site confer specificity.
It can be concluded that the cells CONTAIN ACID FAST BACTERIA.
Acid fast staining is a staining technique that is used to differentiate two types of gram positive cells, those that have waxy mycolic acid in their cell wall and those that do not.
Those cells that do not have mycolic acid in their cell wall will show blue color after acid fast staining.<span />
Different structures and functions of roots
Explanation:
Roots are the underground descending non-green part of the plant.
Root functions: Anchorages the plant to the soil, absorbs water and nutrients from the soil.
Characteristics: Positively geotropic and hydrotropic, negatively phototropic; does not have nodes, internodes or stems.
Types:
- Tap root
- Adventitious root – fibrous, foliar and true adventitious roots
Structure and functions:
- Root cap or Calyptra: Cap-like structure covering the root tip
.
- Function: protects the meristematic tissues of the root, secretes mucilage which enhances the root tips to grow into the hard soil.
- Meristematic zone or growing point sub-terminal behind root cap. These cells are inverted and looks like a dome.
- Function – helps in the root growth by adding new cells to the root tip and other basal regions
- Zone of elongation behind the meristematic zone.
- Function – helps in elongation of the root
- Root hair zone: This is the zone of differentiation where cells differentiate into vascular tissues like phloem, xylem, endodermis, cortex etc.
- The main function of root hair is to increase the total surface area of root to facilitate more absorption of water and other nutrients from the soil
- Zone of maturation: the major and mature portion of a root.
- Function - lateral roots originates from this zone and radial differentiation leads to secondary growth.
Answer:
measure of the intrinsic luminosity of a celestial body (such as a star) expressed as the apparent magnitude the body would have if viewed from a distance of 10 parsecs.
Explanation:
Pinworms are also known as threadworm or seat worm in some countries. Its Scientific Classification:
Kingdom: Animalia
Phylum: Nematoda
Class: Secernentea
Subclass:
There are different types of pinworms in humans and animals. They spread by touching contaminated object they are also parasitic worms.
