Suppose a disease spread through all the red oak trees in a forest economic.

1 answer:

6 0

A: if the oak trees are I'll then it would affect their health which they'll star dying which means that all the biotic organisms that depended on those oak trees for shelter would also start dying which means all the organisms that depended on the oak tree organisms would also die and so on. That way this small change will affect the whole animal community in that area.
B: this change in biodiversity will greatly affect the sustainability of the forest because the animals dying would disrupt the food chain in that ecosystem while killing the whole forest.

When atoms in a covalent bond share electrons unequally (one atoms pulls more than the other), the bond is said to be __________

IrinaK [193]

When atoms in a covalent bond share electrons unequally (one atoms pulls more than the other), the bond is said to be a polar bond is formed when electrons are unequally shared between two atoms. Polar covalent bonding occurs because one atom has a stronger affinity for electrons than the other (yet not enough to pull the electrons away completely and form an ion).

Which of the following things are clues that a chemical change has taken place?

Elena-2011 [213]

Answer:

B. D.

Explanation:

B. because the temperature changes and when it changes a chemical change because there is not heat or coldness to change it with physical change.

D. because you are mixing the colors so that the color of whatever substance you are changing the color of is changing what the specific color was before.

Gwar [14]

Explanation:

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 id water soluble, while the fatty acid tail is a long chain hydrocarbon (hydrogens attached to a carbon backbone) 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. The hydrophilic heads of the bilayer are attracted to water while their water-repellent hydrophobic tails face towards each other- allowing molecules of water to diffuse across the membrane along the concentration gradient.

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 or at as doorways for other molecules to pass through. Cholesterol, which is comparatively rigid, anchors other molecules attached to the membrane, maintain membrane stability or structural integrity and aid in separating some lipids, helping with membrane fluidity at low environmental temperatures.

Remember, essential features:

lipid bilayer
cholesterols
proteins (cell markers and doorways)
