Which structure in the cheek cell did you observe that separates and protects the cell from the environment?

1 answer:

5 0

The answer is epithelium. In particular, stratified squamous epithelium. Epithelium is protective tissue that is found on the outer surfaces of organs and blood vessels and inner surfaces of cavities in many internal organs. Epithelium contains no blood vessels, and nutrients reach the epithelial cells through diffusion from the underlying tissue.

Neurotransmission is unidirectional insofar as chemical and electrical conduction is concerned within the individual neuron. Of

jasenka [17]

Answer: The correct option is C (Dendrites, Cell body, Axon, Axon terminals)

Explanation:

The transfer of information from neuron to neuron takes place through the release of chemical substances into the space between the axon and the dendrites. These chemicals are called neurotransmitters, and the process is called NEUROTRANSMISSION.

The order of neurotransmitter/receptor interaction that results in an electrical signal impulse and the release of another neurotransmitter for interaction in the synaptic cleft (signal conduction through a neuron) is from Dendrites--> Cell body--> Axon-->Axon terminals>

DENDRITES extends from the cell body of a neurone to receive messages at neuromuscular junction from other neurons. The CELL BODY directs all activities to the axon. The AXON is a long single fibre that transmits messages from the cell body and ends in terminals forming a synapse. Nerve impulses arrives at the axon terminal causing the release of neurotransmitters. The neurotransmitters binds to receptors at the dendrites of another neurons. The electrical signal impulses generated causes the release of neurotransmitters in another neuron.

If a spinach plant with flat (FF) green (GG) leaves is crossed (pollination and fertilization occur) with another spinach plant

never [62]

Answer:

The offsprings of this cross will inherit the flat (F) and green (G) alleles from the first parent and also the crinkly (f) and purple (g) alleles from the second parent. However, the offsprings will only inherit the flat, green traits.

Explanation:

This question involves two different genes coding for leaf shape and leaf color respectively. The alleles for flat (F) and green (G) leaves are dominant over the alleles for crinkly (f) and purple (g) leaves.

According to this question, If a spinach plant with flat (FF) green (GG) leaves is crossed with another spinach plant with crinkly (ff) purple (gg) leaves, all the offsprings in the F1 generation will possess a FfGg heterozygous genotype.

This genotype means that the F1 offsprings of this cross will inherit the flat (F) and green (G) alleles from the first parent and also the crinkly (f) and purple (g) alleles from the second parent. However, they will only inherit the flat, green traits because they are dominant over the crinkly and purple trait.
