Point where crossing over takes place between chromatids of the homologous chromosomes during prophase 1

Biology
1 answer:
Free_Kalibri [48]2 years ago
3 0

Answer:

Crossing over occurs during prophase I of meiosis before tetrads are aligned along the equator in metaphase I.

Explanation:

When chromatids "cross over," homologous chromosomes trade pieces of genetic material, resulting in novel combinations of alleles, though the same genes are still present. Crossing over occurs during prophase I of meiosis before tetrads are aligned along the equator in metaphase I.

Which of the following samples has the greatest population density?
Andrews [41]

The right answer is D.

The density of a given population is calculated by dividing the number of inhabitants by the area expressed in km² (or in hectares).


Number of inhabitants ÷ area (in km²) = number of inhabitants / km²



A = 125000 organism/ 2.5 m2 = 50,000 organisms / m2


B = 13000 organisms / m2


C = 37500 organisms / m2


D = 200000 organisms / m2

Stacey wants to know if plants have the same phototrophic reaction from artificial light as they do from natural light. Using st
joja [24]

Scientific method includes some steps that are necessary for conducting the successful experiment.

1. Make an observation

You observe the growth of the plant under the influence of light (phototropic effect) and you notice that some plants successfully grow under artificial light. You want to compare that growth with growth under the sunlight.

2. Ask a question

How does the light influence plant growth?

Are the wavelengths of the light important?

Is natural light source (sun) better for plant growth...

3. Form a  hypothesis - it is a testable potential answer to the question

For example: Sunlight induces higher phototropic reaction.

4. Make a prediction

Sunlight is richer in red and blue hues which are both extremely important to plant growth.  

5. Test the prediction

Design an experiment by putting one pot with beans outside on sunlight and other under the light bulb. Other conditions such as water must be the same. Monitor their growth for about 2 weeks and measure the results.

6. Analyze the data and make a conclusion.
