Gravity: A force that keeps things in place sonit doesnt float around.

Mass: The amount of matter or substance that makes up an object

Weight: How heavy or light something is

Inertia: property of matter by which it continues in its existing state of rest or uniform motion in a straight line, unless that state is changed by an external force.

What are the products of photosynthesis? Where do they go?
Soloha48 [4]
Oxygen and glucose are the products of photosynthesis. Oxygen is used by plant for respiration or it gets dissipated in the air. Glucose is stored for feeding the plant. It is also stored in the form of starch

Serves as the molecular basis for life. DNA copies itself via the process of . RNA is produced from DNA via the process of . Pro
blagie [28]

Answer:

CGTCATC

Explanation:

In a DNA double helix, the complementary bases of two strands of DNA are paired by hydrogen bonds. Adenine of one DNA strand is paired with the thymine of the other strand. Similarly, the guanine of one DNA strand is paired with the cytosine of the other DNA strand. If a portion of one of the two strands of a DNA molecule has the sequence GCAGTAG. The sequence of the other strand would be as following:

One DNA strand: GCAGTAG

Other DNA strand: CGTCATC

The structure of the cell membrane allows it to be selectively permeable. What is the name for the larger, brown structure in th
Anika [276]

Explanation:

B) protein channel

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 <em>diffusion,</em> 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. Carrier proteins and channel proteins are the two major classes of membrane transport proteins.

  • Carrier proteins (also called carriers, permeases, or transporters) bind the specific solute to be transported and undergo a series of conformational changes to transfer the bound solute across the membrane. Transport proteins spanning the plasma membrane facilitate the movement of ions and other complex, polar molecules  which are typically prevented from moving across the membrane.
  • Channel proteins which are pores filled with water versus enabling charged molecules to diffuse across the membrane,  from regions of high concentration to regions of lower concentration. This is a passive part of facilitated diffusion

which plane velocity was greatest? Yeagers Bell x-1, The Concorde, SR71 blackbird, none they all traveled at the same speed.
Stels [109]

Answer:

The SR-71 Blackbird.

Explanation:

The Lockheed SR-71 "Blackbird" was an American strategic reconnaissance aircraft that traveled at over mach 3, or 3 times the speed of sound. The Concorde was a French passenger jet with a top speed of just over mach 2. The Bell X-1 was the first supersonic test plane and had to be dropped from a larger plane to reach altitude.
