Answer:
Layer A: inner core
Explanation:
The solid, inner core (Layer A) is comprised mainly of iron and nickel and is scorching hot. The outer core (Layer B) does have iron and nickel as well, but it's in its liquid form. The lower mantle (Layer C) consists of iron-rich perovskite, which is a ferromagnesian silicate mineral. The upper mantle (Layer D) is made of olivine, pyroxene, calcium oxide, and aluminum oxide.
Alleles positioned on the same chromosome are not always inherited together because during meiosis linked genes can became separate genes.
Answer:
Increase the membrane surface area which creates more work space
Explanation:
Mitochondrion (Plural-mitochondria) is referred to as the powerhouse the the cell because it is the site of ATP (energy rich compound) synthesis in the cell. Mitochondria are shaped perfectly to maximize their productivity. They are made of two membranes; the outer membrane, which sheds the organnelle and contains it like a skin and the inner membrane, which folds over many times and creates a layered invagination called CRISTAE.
The folding of the inner membrane increases the membrane surface area inside the organnelle. Since many of the chemical reactions e.g. Cellular respiration (ETC and Chemiosmosis) occur in the inner membrane, the increased surface area creates more space for the reactions to occur.
It is just reasonable that the more the space, the more the work that can be done.
The decidua basalis is the name for the maternal portion of the placenta. Oxygen and nutrients from the maternal blood permeate through the villi's walls and into the fetal capillaries in the inter-villous gaps.
<h3>What is Placental membrane ?</h3>
Blood from the mother and the fetus are separated by the placental membrane. The chorion is the name for the fetal portion of the placenta. The decidua basalis is the name for the maternal portion of the placenta.
At eight days after ovulation, the blastocyst is fully entrenched in the endometrial stroma in humans. Fibrin covers the entry point, and endometrial epithelial cells develop on top of it to further embed the blastocyst in the endometrium (Bischof and Campana 1996).
The uterus houses the placenta, a transient pregnancy organ. It is made up of elements from the mother and fetus. The chorion frondosum creates the fetal portion, and the decidua basalis creates the maternal portion.
