The excretory system is intended to remove any solid/fluid waste from your body, such as urine.
Answer:
44
Explanation:
A somatic cell is diploid - it has 46 chromosomes. Half of these are from the mother, so there are 23 maternal chromosomes
A sex cell (gamete) is haploid - it has 23 chromosomes. There are (usually) two sex chromosomes in a diploid genome, either XX or XY, so there is one 1 in a haploid cell, giving a total of 22 autosomes
Barr bodies are inactive X chromosomes in a female somatic cell. This occurs to control dosage compensation (otherwise all the genes on the X in females would be expressed twice as much as they are in males). In a healthy female, there is normally one Barr body
A person with Kleinfelter's syndrome has two X chromosomes and one Y (XXY). They are biologically male, but have two X chromosomes. Therefore, one of these becomes a Barr body, as in females.
23 + 22 - 1 = 44
Pressure decreases as magma rises.
Pressure increases until the volcano explodes.
Explanation:
The reason behind volcanic eruption is extreme weather, tectonic plates, climate change and magma movement. Under beneath of earths crust there are molten rock which is formed because of high temperature at core and they are melted and form a magma.
In magma there are various types of gas present. These gases are carbon dioxide, water vapor and also sulfur dioxide. These gases are stored in chambers of magma and it sealed beneath with lid of rock
The endosperm provides nourishment.
