kherson [118]3 years ago

Explanation:

True

Lipids are composed of fatty acids which form the hydrobic tail and glycerol which forms the hydrophilic head; glycerol is a 3-Carbon alcohol which is water soluble, while the fatty acid tail is a long chain hydrocarbon (hydrogens attached to a carbon backone) with up to 36 carbons. Their polarity or arrangement can give these non-polar macromolecules hydrophilic and hydrophobic properties. Via diffusion, small water molecules can move across the phospholipid bilayer acts as a semi-permeable membrane into the extracellular fluid or the cytoplasm which are both hydrophilic and contain large concentrations of polar water molecules or other water-soluble compounds.

Similarly via osmosis, the water passes through the membrane due to the difference in osmotic pressure on either side of the phospholipid bilayer, this means that the water moves from regions of high osmotic pressure/concentration to regions of low pressure/ concentration to a steady state.

Further explanation:

Transmembrane proteins are embedded within the membrane from the extracellular fluid to the cytoplasm, and are sometimes attached to glycoproteins (proteins attached to carbohydrates) which function as cell surface markers. Carrier proteins and channel proteins are the two major classes of membrane transport proteins; these allow large molecules called solutes (including essential biomolecules) to cross the membrane.

Carrier proteins (also called carriers, permeases, or transporters) bind the specific solute to be transported and undergo a series of conformational (shape) changes to transfer the bound solute across the membrane. Others cross the membrane through the process of endocytosis, which utilizes membrane-bound organelles for transport.

The ratio of estrogen to progesterone remains constant throughout pregnancy into labor. false/true
Lady_Fox [76]

False,

In order to start labor, estrogen increases and progesterone decreases.

Estrogens are a class of hormones that are essential for women's healthy sexual and reproductive development. They are sex hormones as well. The majority of estrogen hormones are produced by a woman's ovaries, however minor quantities are also produced in modest amounts by the adrenal glands and fat cells.

Progesterone is a member of the progestin drug class (female hormones). By lowering the level of estrogen in the uterus, it functions as a component of hormone replacement treatment. By substituting for the natural progesterone that some women lack, it helps to initiate menstruation.

Assuming that other factors are equal, how are the immigration and
ludmilkaskok [199]

The immigration rate and the emigration rate are equal in case of a stable population.

Option A

<h3><u>Explanation:</u></h3>

A stable population is defined as the number of individuals residing in an environment with a limited resources and the number of individuals residing more or less remains constant. In case of a population, there are different factors which tends to divert the population out of the stability, like immigration or emigration. Immigration is the addition of individuals to the population from outside which increases the population, and emigration is the loss of individuals which decrease the population. In case of a stable population, the number of immigrants and emigrants remain more or less same, which maintains a stable population.
