The cell membrane has____. a) polar heads on the outside and nonpolar fatty acids on the inside b) nonpolar fatty acids on the outside and a polar heads on the inside c) polar heads on both inside and outside d) nonpolar fatty acids on both inside and outside
Answer:
a) polar heads on the outside and nonpolar fatty acids on the inside
Explanation:
The cell membrane is made up of phospholipids arranged in a bilayer, where hydrophilic polar (negatively-charged) heads of phospholipids interact with water molecules (i.e., aqueous surrounding media). Moreover, non-polar (uncharged) fatty acid tails are hydrophobic because they cannot be dissolved in water. Thus, the bilayer cell membrane is a structure where non-polar fatty acid chains are localized in the inner region (away from the water), while hydrophilic phosphate heads face outward, interacting with water on both sides of the cell membrane.

Answer:
Pick Hydrogen, but read below.
Explanation:
The blacks are Carbon. They have 4 connections. The left Carbon has 3 whites connected to it. It is not totally an exclusive answer, but the whites could be anything in Column 17 (F, Cl, Br, I) or Hydrogen. Likely it is hydrogen.

The movement of waves in the middle of the ocean is normally
static
vertical
circular
horizontal
Answer:
Vertical
Explanation:
Since we are talking about movement, and the ocean can't be static due to many things happening around and inside it can't be static.
It is not circular and not horizontal. It is vertical. The movement of waves is vertical and this is because waves don't move up and down but vertically since wind is the usual maker of waves in the middle of the ocean.
What are the various functions of proteins embedded in the cell membrane?
Answer:
Proteins embedded within the phospholipid bilayer carry out the specific functions of the plasma membrane, including selective transport of molecules and cell-cell recognition.
Explanation:
In coastal areas, the large amount of salt in the air and water determines which species can exist there. In these areas, the salt functions as a
A
source of energy
B
growth catalyst.

D
food source
Answer:
D
Explanation:
the salt provides for some animals
In the areas where amount of salt in the air and water determines species that can exist the salt functions as a ; ( D ) Foodsource
Meaning of Food sourceGiven that salt is an essential part of food and the amount of salt in the air and water determines the species located in an area ( coastal area ), the salt in this scenerio will function as a food source responsible for the existence of species.
Hence we can conclude that In the areas where amount of salt in the air and water determines species that can exist the salt functions as a ; ( D ) Foodsource

Explanation:
What type of articulation moves the least?
O cartilaginous joints
o fibrous joints
o synovial joints
O ball-and-socket joints
The answer is Fibrous joints
Answer:
fibrous joints
Explanation:
There is no cavity, or space, present between the bones and so most fibrous joints do not move at all, or are only capable of minor movements.

Explanation:
A rock has been sent on a journey down through the layers of the Earth until it reaches the inner core. Explain what happens to the atoms in the rock as it moves through each layer.
Answer:
The rock components of the crust are slowly but constantly being changed from one form to another and the processes involved are summarized in the rock cycle (Figure 3.2). The rock cycle is driven by two forces: (1) Earth’s internal heat engine, which moves material around in the core and the mantle and leads to slow but significant changes within the crust, and (2) the hydrological cycle, which is the movement of water, ice, and air at the surface, and is powered by the sun.The rock cycle is still active on Earth because our core is hot enough to keep the mantle moving, our atmosphere is relatively thick, and we have liquid water. On some other planets or their satellites, such as the Moon, the rock cycle is virtually dead because the core is no longer hot enough to drive mantle convection and there is no atmosphere or liquid water.

7. Products like "Tums" neutralize stomach acid because Tums is a a. neutral. b. base. c. acid.
Answer:
(B) Products like "Tums" neutralize stomach acid because Tums is a base.
Explanation:
If the product neutralizes an acid, that means it must be a base. Acid + Base = Neutral. If you were to consume an product that is acidic, the stomach will end up being overly acid, which is unsafe for the body. If you were to consume a product that is neutral or "normal", the product would not do as much to neutralize the stomach acid, compared to a more basic pH. Tums has a main ingredient of calcium carbonate, CaCO3, a base. This ingredient helps regulate the pH levels for your stomach so that it does not become too acidic.
