Answer:

From the diagram X = <u>base pairs</u>

Explanation:

Genetic information stored within DNA is used for growth, reproduction, and cell repair. DNA, deoxyribonucleic acids, are long-chain, helical macromolecules made of specific sequences of covalently bonded monomers called nucleotides.

Nucleotides comprise:

  • a 5-Carbon deoxyribose sugar,
  • one nitrogenous base (adenine, guanine thymine, and cytosine)
  • and a phosphate group.

Nitrogenous bases cause nucleotides to form hydrogen bonds with other nucleotides as base-pairs. The four types of bases each make the nucleotides  Thymine and Cytosine (pyrimidine bases) along with Guanine,  and Adenine, (purine bases). In base-pair formation, Adenine forms double bonds with Thymine, and cytosine forms triple bonds with guanine.

A ligand can bind to two receptors, A and B. The Kd for receptor A is 0.001 nM and the Kd for receptor B is 1 nM. Based on the e
Pavlova-9 [17]

Answer:

The answer is: Receptor A because the ligand concentration is greater than the Kd.

Explanation:

Receptor A because the ligand concentration is greater than the Kd., because the conformation of a receptor protein composes the functional state. Ligands include substrates, inhibitors, activators, and neurotransmitters. So, Affinity is a measure of the strength of attraction between a receptor and its ligand.

To approximate vocal frequencies, which tuning fork should be used to assess hearing?
VladimirAG [237]
The vestibulocochlear nerve mediates hearing and balance. Hearing can be assessed with a 512-Hz tuning fork. The Rinne and Weber tests are commonly used to assess for sensorineural and conductive deafness.

A damages axon in the PNS may be able to regenerate only if the cell body is intact. Why do you think that the cell body must be
Sonbull [250]

Answer:

Explanation:

The central nervous system (CNS) does not have capacity to repair itself but, the PNS or the peripheral nervous system can repair and regenerate itself. The PNS can regenerate its damaged axon only when its cell body or cyton and its neurilemma are intact. The proximal end of the cyton has growth cones. The axon grows from the cones.

Two organisms that have sexual and two that have asexual reproduction?
Ipatiy [6.2K]

Answer: Sexual reproduction: rabbits and dolphins.

Asexual reproduction: Strawberry and potato.

Explanation:

  • Sexual reproduction is carried out with the participation of germ cells from two stem organisms - female and male, which transfer the properties of the inherited material to the new plant. The main characteristic of sexual reproduction is the division of the relative fusion of male and female sex cells. The end product of this relationship is the creation of an organism that contains the genetic information of both parents.
  • Asexual reproduction is a habit that produces an organism identical to the parent organism, and we call this product clones. This form of reproduction does not involve the germ cells and may occur by division or budding. Many types of plants reproduce in this way. So the strawberries are propagated by boils, and the potatoes are buds from the tub
