Answer:
passive transport and diffuision
Explanation:
it requires no energy from the cell. Examples include the diffusion of oxygen and carbon dioxide, osmosis of water, and facilitated diffusion. diffusion does not.
The SI unit of temperature is the Kelvin. Although the Celsius temperature scale is also used, it is considered a derived SI unit and is generally used to measure everyday temperatures.
Answer:
A series of nonpolar amino acids would most likely be located in the interior region of the tridimensional molecule.
Explanation:
Proteins are formed by linearly arranged amino acids, each with a side chain: the R-group.
Of the 20 different amino acids that compose the proteins, about half of them -10- are non-polar. Their R-groups are not stable if they are in contact with water, meaning that non-polar amino acids are hydrophobic.
When proteins are synthesized, they acquire a three-dimensional structure that makes them more stable. Lineal polypeptides get folded and turn into a shape that makes them more stable in the environment and capable of accomplishing their biological role. When they are in an aqueous media, their bent shape leaves the hydrophilic R-groups in contact with water. The hydrophilic R-groups stick in the center of the polypeptide, facing the protein interior, and avoiding interaction with water.
Answer:
The correct answer is: True.
Explanation:
- The writing of a person is controlled by an region located in the left part of frontal lobe of the brain which is known as the Broca's area.
- Writing is a motor impulse send by the brain to the hand and fingers.
- However, no two individual can have the same hand-writing.
- This is because hand-writing is not only dependent on the brain to hand motor co-ordination.
- It also depends upon the psychology, mentality, thought process, state of mind, nature of the person and also the influence of the surroundings on the person.
- It also depends on the preference of the person to keep his writing artistic or simple or illegible.
- All these factors can never match between two persons.
- This is the reason, no two persons can share the exactly same hand-writing.
This implies that the gametophytes can easily lose water to, and absorb water from, the atmosphere.
Moss is a flowerless, spore-producing pant. The main moss structure is the gametophyte, a moss's stem and leaves. A moss stem also the axis supports leaf-like structures that carry out photosynthesis, transforming sunlight into sugars the moss uses for food.
