Answer: D
Explanation:
3' C C T A G G C (T) G C A A T C C 5'
The primer RNA will be 5' A C G U U A G G 3'
Polymerization of the new stand is taking place from 5' to 3' direction. This means the the template strand is read from 3' to 5' direction.
In DNA synthesis chargaff base pairing rule is always maintain. If ''A'' is present on the template strand ''T''enters in that place on the newly synthesized DNA .
RNA primase synthesizes this short primer. RNA primer contains RNA nucleotides this means If ''A'' is on the template strand, the RNA primer will be ''U''
Answer:
ground tissue- is the most common type of plant tissue found in the interior of the plant and can support, store and provide photosynthesis for the plant. Made up of 3 basic plant cells ( Parenchyma, Collenchyma, and Sclerenchyma cells)
dermal tissue- Provides cover and protection for plant. Usually found on the outside similar to skin. Epidermis cells make up the dermal layer and secrete a waxy substance called the cuticle that also protects the plant.
vascular tissue- includes xylem & phloem and helps with water and food transport. The xylem and phloem are kept together in vascular bundles running throughout the ground tissue.
meristem tissue- is growth tissue. This tissue made up of rapidly dividing cells and can be found at the tips of the roots and stems of plants. the growth areas of tips of roots and stems is called APICAL MERISTEM and the secondary growth that makes a plant wider is called LATERAL MERISTEM.
Explanation:
The correct answer is option B, that is, covalent bonds.
Covalent bonds are more prevalent in organic chemistry in comparison to ionic bonds. A covalent bond comprises of the concurrent attraction of two nuclei for one or more electron pairs. The electrons situated between the two nuclei are known as bonding electrons.
Covalent bonds take place between different atoms or similar atoms whose difference in electronegativity is not enough to permit the transfer of electrons to produce ions. The covalent bond is demonstrated by either as a solid line or long dash or as a pair of dots.
Answer:
Xerophyte survival characteristics:
Thick cuticle.
Stomatal closure.
Reduction in # of stomata.
Stomata hidden in crypts or depressions in leaf surface (less exposure to wind and sun).
Reduction in size of transpiration surface (lower leaf only).
Increased water storage.
Explanation:
Xerophyte adaptations increase water intake, limit water loss, and store water efficiently. Water intake adaptations include deep or widespread roots, and high salt content to increase osmosis. Xerophytes have thick cuticles, lost or finely divided leaves, reduced stomata, and CAM photosynthesis
Answer:
limiting factors
Explanation:
The ecological optimum represents the value of the factors within the ecological valence at which the life processes of a species take place best. The upper and lower limits of an ecological valence are its maximum and minimum. Beyond these limits, physiological processes are interrupted and death occurs.
