an egg cell has a haploid nucleus so it has half the number of dna because it fuses with a sperm cell to have the full amount of dna.
an egg cell has 23 chromosomes and a sperm cell has 23 chromosomes.
they both have half the amount of dna to form a zygote
I think that these are A climate changes because they both got fur to match the snow/winter climate
I know it's not C cause this has nothing to do with food, and i don't think it's B either, so I think the best answer choice would be A
Answer:
Separating a cell into 2 different parts allows for the creation of specific environments in a cell.
Explanation:
Separating a cell into 2 different parts allows for the creation of specific environments in a cell.One example would be Nuclear Envelope.The nuclear envelope is a double membrane Where the two membranes are separated by space.Another example would be the Endoplasmic Recticulum. The endoplasmic recticulum has two different parts which are the smooth er and the rough er. The smooth er is smooth at the top because it lacks ribosomes.The rought er is rough because it has studded ribosomes on the outer surface of the membrane.
Answer:
This is refers to as Greenstick fracture.
Explanation:
This is the type of fracture common in children less than 10 years, in which there is incomplete fracture of the bone,with ,but the cortex remain flexed.It is called green stick because it is analogous to the act of breaking a branch of a tree, which is not completely broken, from the main branch.
It is usually to due to falls,and common in kids because of their soft bones which is not completely formed and therefore will not break off completely like that of adults when fractured, but only from one side only.
The two events in earth's history with great impacts on carbon cycle is the burning of fossils fuels and the change in land use and land cover. burning of fossils fuels in homes and industries extracts the carbon from the fossil fuel and emit it as carbon dioxide in the atmosphere. change in land use such as deforestation also change the amount of carbon in circulation.
