Answer: b (mutations in sex cells can be passed on to children)
Answer:
Answer.
Explanation:
Maybe he did not label the X and Y axis? And notice how AB is wider than the other three test results? that could be a mistake too.
Answer:
The statistics
Explanation:
Mendel experiments were different because he used peas because they were cheap, they grow relative fast, they have different kind of plants, that mean that he can focus in one characteristic at a time, like the color, the shape, the texture, etc.
So since he can do numbers with his results, the statistics were easy to do, were easy to observe the patterns in real life so he can do in theory other traits even in humans.
Hope this info was useful.
Answer:
The model showing the condition must represent a recombination between the X and Y chromosome during meiosis in male.
Explanation:
In males, the sex chromosomes are X and Y, whereas, the females have XX chromosomes. When the X chromosome of males fuses with the female gamete it give rise to a female progeny.
The Sry gene is present on the Y chromosome. In some cases, the recombination between the X and Y chromosome during meiosis in males takes place and result in an X chromosome containing Sry gene. This Sry gene is responsible for the male characters and progeny carrying two X chromosomes, in which one has the Sry gene would have the male characters.
So, the in this case should represented the crossing over between the X and Y chromosomes in males and then passing of the Sry containing X chromosome to progeny.
Answer:
The correct answer is D cells interact with other cells for regulation and homeostasis.
Explanation:
The increase in blood glucose level after intake of carbohydrate rich meal,generate a signal for the release of peptide hormone insulin from the beta cells of pancreas.
The released glucose then travels through blood stream and interacts with insulin receptors on the target cells such as liver,muscle,heart cells,brain cells etc and helps these organs to uptake glucose from blood stream thus reducing the blood sugar label.
Thus one cell interact with another cell for regulation and homeostasis.
