Place the following events of a reflex arc in the correct order: 1) motor neuron activation, 2) sensory neuron activation, 3) se
VikaD [51]

Answer:

The reflex arc follows this sequence of events

1. sensory receptor activation

2. sensory neuron activation

3.information processing

4. motor neuron activation

5. effector response

Explanation:

Reflex arc is the pathway of nerves during a reflex action. An example of a reflex arc is when we accidentally touch a hot object. First, the receptor in the skin detects a stimulus in this case the change in temperature. Second, the sensory neuron transmit the electrical impulses to the Central Nervous System for information processing. Then relay neurons connect sensory neurons to motor neurons. Third, motor neurons sends electrical impulses to an effector wherein the effector produces a response ( muscle contracts to move the hand away from the hot object. This happens in a split of seconds.

Part A - Independent assortment of three genes A wild-type tomato plant (Plant 1) is homozygous dominant for three traits: solid
Effectus [21]
<h2>Law of independent assortment </h2>

Explanation:

  • There are 8 distinct phenotypes, each one has a 12,5% of appearance: Since M=solid leaves D=normal height P= smooth skin.
  • Recessive gene characters can only be taken in homozygous recessive mmddpp.  

      1. MmDdPp: M=solid leaves D=normal height P= smooth skin.

     2. MmDdpp M=solid leaves D=normal height pp= peach skin.

    3. MmddPp M=solid leaves dd=dwarf height P= smooth skin.  

    4. Mmddpp M=solid leaves dd=dwarf height pp= peach skin.

    5. mmDdPp mm=mottled leaves D=normal height P= smooth skin.  

    6. mmDdpp mm=mottled leaves D=normal height pp= peach skin.  

    7. mmddPp mm=mottled leaves dd=dwarf height P= smooth skin.  

   8. mmddpp mm=mottled leaves dd=dwarf height pp= peach skin.

Hence,The answer is all eight possible phenotypes from the cross MmDdPp x mmddpp are equally likely, resulting in a phenotypic ratio of 1:1:1:1:1:1:1:1

The nitrogen base pictured is adenine. Is this nucleotide considered a purine or a pyrimidine? There is a molecule, a base of wh
Vlad [161]

Answer: Purine

Explanation:

A purine is a nitrogenous base found in nucleic acids, and contains a 6-membered pyrimidine ring fused to the 5-membered imidazole ring. The most common examples of purine bases are adenine and guanine.

Thus, the nitrogen base pictured is adenine, and the nucleotide considered is a purine
