Sperm and egg cells do not go through mitosis, they go through meiosis. Why? Well, in mitosis, cells copy themselves. But in sperm and egg cells, they have to duplicate differently. So, there is no such thing as two different sperm or egg cells that are the same.
Answer:
Explanation:
First, let's identify the tools needed.
Since the biology class is studying the temperature, they will likely need a <u>thermometer</u>. Also, they are gathering information about the growth of the plants. This could use a <u>balance </u>of a meterstick.
Next, recall the difference between quantitative and qualitative data.
- <u>Quantitative</u>: Measurable and numerical results found using scientific instruments/devices
- <u>Qualitative</u>: Data found using the senses, such as descriptions and diagrams.
Since the class is measuring temperature and growth using tools, it must be quantitative data.
We can eliminate choices A and B, because they claim the class will gather qualitative data. Then, we can eliminate choice D, because a beaker and timer won't help with temperature and growth. That leaves choice C as the correct answer.
Answer:
1. 0% of probability, 2. 50% of probability, 3. 75% of probability.
Explanation:
In order to find the probabilities we have to draw Punnet squares. The mutated gene will be symbolized with a *.
1. Male CC with female CC, there is no mutation, the probability will be 0%.
X Y
X ║ XX ║ XY
X ║ XX ║ XY
2. The male has not got a mutation and the female has. When we draw the Punnet square, with one female X mutated, we find that there is a 50% of probability of mutation.
X Y
X* ║ X*X ║ X*Y
X ║ XX ║ XY
3. Now both, the female and the male, has the mutation. When we draw the Punnet square with mutations in the female and in the male, we find that there is a 75% of probability of mutation.
X* Y
X* ║ X*X* ║ X*Y
X ║ XX* ║ XY
The ability to reproduce sexually or asexually
false
is the answer because their is no such things of molecule
