aleksklad [387]

Answer:

Suppression of Abl reduces the severity of abnormal axonal guidance in PTP mutants

Explanation:

Axon guidance is a neural development subfield relating to the mechanism by which neurons send out axons to meet their right targets.

ABL gene is a protooncogene that encodes a protein tyrosine kinase involved in a variety of cellular processes. PTPs are known to signal a number of cellular processes, including cell development, differentiation, mitotic cycle, and oncogenic transformation.

Suppression of Abl reduces the severity of abnormal axonal guidance in PTP mutants.

The permeability of ______ in the second coiled tubule of the nephron is controlled by _______.
Dmitriy789 [7]

Answer:

distal tubule, the concentration of ADH

Explanation:

Nephron is the functional unit of kidney. Nephron undergo reabsorption and secretion along different part.

The permeability of distal tubule to water in the second coiled tubule of the nephron is controlled by the concentration of ADH. The concentartion of ADH controls the degree of dilution or urine concentration. High ADH level makes , tubules permeable to water while the absence of ADH makes them impermeable to water.

Hence, the correct answers for blanks are distal tubule and the concentration of ADH.

nadya68 [22]

Answer:

See the answer below

Explanation:

<em>Both conclusions can be valid because they are based on valid data and scientific reasoning.</em>

In order for a data to be valid in making a conclusion, such data must have been collected through a scientific experiment that is devoid of subjectivism. In order words, the data must have been objectively collected via standard experimental procedures.

Once data have been collected, they are analyzed and used to make valid conclusions based on the hypothesis which must have been made earlier before the experiment.

Conclusions made from standard experimental procedures and scientific reasonings are valid and such experiments are reproducible.

<em>Hence, as long as the data from which the conclusions were made can be reproduced through the same experiments, the conclusions are valid.</em>
