Bacterial flagella have which functions? check all that apply

1 answer:

7 0

Option A and B. They are the organelle of locomotion for most bacteria capable of motility. And, a motile response to an environmental stimulus. Bacterial flagella are helical filaments made up of the protein flagellin 20-nanometer-thick with a rotary motor at its base which can turn clockwise or counterclockwise. Like the multicellular flagellum the primary role of the flagellum is locomotion, bacterial mobility, but it often functions as a sensory organelle in response to external stimuli like exposure to chemicals and temperatures outside the cell.

Arisa [49]

Answer:

See the answer below

Explanation:

Let the disorder be represented by the allele a.

Since the disease is an autosomal recessive one, affected individuals will have the genotype aa and normal individuals will have the genotype Aa or AA.

Since the four adults are carriers, their genotypes would be Aa.

Aa x Aa

Progeny: AA 2Aa aa

Probability of being affected = 1/4

Probability of being a carrier = 1/2

Probability of not being affected = 3/4

(a) The chance that the child second child of Mary and Frank will have alkaptonuria = 1/2

(b) The chance that the third child of Sara and James will be free of the condition = 3/4

(c)

(d) If someone has no family history of the disorder, their genotype would be AA.

AA x aa

4 Aa

The chance that a child with alkaptonuria will have an offspring with alkaptonuria if the child's mate has no family history = 0

(e)

(f) The chance that a child with alkaptonuria will have an offspring with alkaptonuria if the child's mate has no family history = 0

AlekseyPX

Answer:

True

Explanation:

Sensory neurons are the neurons present in the nerves which can convert the external stimuli into an electrical signal and can transmit the signals from the organs to the central nervous system.

The structure of sensory neuron in pseudounipolar that is at one end it has dendrites and another end transmits the signals to the CNS. The cell bodies (nucleus) of these sensory neurons are located in the structures called ganglia located outside the CNS.

Thus, True is the correct answer.
