Answer:
Can you please insert a picture of the chart so that i can write your conclusion?
Explanation: thanks
Meiosis I
Prophase I - homologous chromosomes form a tetrad, where they begin cross-over through the process of synapses.
Metaphase - homologous chromosomes then align along the metaphase plate.
Anaphase I - spindles then separate the homologous chromoses, pulling them to opposite poles of the cell
Telephase I - the cell creates a cleavage burrow inwhich the cell divides into two new cells with 46 chromosomes in the process of cytokinesis
Meiosis II
The same as mitosis
Prophase II - Nuclear envelope disintegrates, Sister chromatids migrate towards the metaphase plate.
Metaphase II - Sister chromatids align along the plate by their centromere.
Anaphase II- spindles pull the chromatin to opposites poles
Telephase II- cleavage burrow forms and cells seperate through cytokinesis
end result
4 haploid gametes are formed
Answer:
The given statement is False.
Explanation:
During the prophase stage of mitotis, the chromatin starts becoming more condense. Histone protein is a basic protein which is responsible for initial and basic packaging of chromatin into nucleosome.
The second level of chromatin packaging occurs when the nucleosomes are arranged in the fiber which has a diameter of about 30nm. Each nucleosome is attached with H1 histone and nucleosome fiber coil to form a solenoid structure which has a diameter of 30nm. Therefore the statement is false.
I believe the answer is true. Hope this helps !!
White blood cells fight infections from bacteria, viruses, fungi. and other pathogens (organisms that cause infection). One important type of white blood cell is the neutrophil. These cells are made in bone marrow and travel in the blood throughout the body. They sense infections, gather at sites of infection, and destroy the pathogens.
When the body has too few neutrophils, the condition is called neutropenia. This makes it harder for the body to fight off pathogens. As a result the person is more likely to get sick from infections. In general, an adult who has fewer than 1,000 neutrophils in a microliter of blood has neutropenia.
If the neutrophil count is very low, (fewer than 500 neutrophils in a microliter of blood), it is called severe neutropenia. When the neutrophil count gets this low, even the bacteria normally living in a person's mouth, skin, and gut can cause serious infections.
