Answer:
Metaphase I
Explanation:
Homologous chromosomes are paired to facilitate crossing over during prophase I of the meiosis I. This is followed by alignment of homologous chromosomes at the equator of the cell during metaphase I. The process is assisted by microtubules of spindle apparatus. The kinetochore microtubules of the spindle apparatus attach themselves to the kinetochores of chromosomes.
The two sister kinetochores of duplicated homologous chromosomes are attached to the opposite pole to align the homologous pair at the center of the cells. Metaphase I is followed by anaphase I during which homologous chromosomes move towards the opposite poles.
Answer:
A food web consists of many food chains. A food chain only follows just one path as animals find food. eg: A hawk eats a snake, which has eaten a frog, which has eaten a grasshopper, which has eaten grass. A food web shows the many different paths plants and animals are connected.

Explanation:
I would like to photograph a tulip, because I have always been interested to know more about some flowers and what’s in the inside of them. Even though tulips look pretty “simple” but beautiful in the outside, I suspect that there are a thousand of different things inside of it.
The Benedict’s Test is the test which can detect carbohydrates and glucose in foods. During this process, the sample or the food is placed into a test tube and then some drops of Benedict's solution is added to it,and is then put into a beaker of boiling water. When the mixture of food and the Benedict substance turns reddish orange instead of staying blue, this means that it is positive. The mixture has simple sugar or has carbohydrates or glucose. On the other hand, lipids are tested using the brown paper test. When the paper turns transparent when a drop of food is put into it, it means that is is positive as well. When you want to test if the food has proteins, you have to test it with Biurets. Observe if the color change when you put some Biurets solution to the food sample. It is positive if the food turns light purple. Test if the food is positive with starches through the use of iodine. Food having iodine drops should turn purple instead of staying a yellow color.
