Answer:
Substances are gaining energy as they move from an area of low concentration to an area of
high concentration.
Substances are moving from an area of low concentration to an area of high concentration,through a protein channel, using energy.
Explanation: Active transport is the transfer of materials from areas of low concentration to areas of high concentration which requires energy.
One component of the cell theory is A cell is the basic unit of structure and function of all organisms. Thus, option "D" is correct.
The cell contains genetic material in the form of DNA which is passed from the parent cell to the daughter cells after cell division.
All cells are similar in chemical composition as well as in metabolic activities.
All the physiological and biochemical functions usually take place inside the cell.
The activity of the cell depends upon the cell organelles and other cellular parts.
Thus, option "D" is correct.

Explanation:
All other options are wrong
Answer:
Explanation:
Whales and humans have alot of things in common, they are the largest groups of mammals in the world.
Whales which belong to cetaceans(group of marine mammals) can be considered human, they possess self awareness, feelings and high-level cognitive power than man.
They have large brain size which suggests that they have a complex and elaborate evolutionary history.
Humpback cerebral cortex, the part of the brain where though processes takes place are similar to that of man. Humpback whales exhibit complex social patterns that include good communication skills, collaboration and good tool usage.
Whales and human are quite social in nature.
Answer:
A whale's fin is a major homologous structure. When you examine a whale's skeleton, you'll find that all of its bones are comparable to those of other mammals. As mammals, whales share a common ancestor with other mammals, including humans. Humans and humpback whales belong to the same kingdom (Animalia), phylum (Vertebrates), and class (Mammals) which means they are related but not too close. Humpback whale embryos still have limbs, but when they become adults, they become dormant, meaning the ancestor of today's humpback whale walked on land with humans in the past and therefore may have some evolutionary relationship with us.

all of the above
Answer;
All the above
All the above processes (crystallization, erosion, and compaction) may be used during rock cycle to form new rocks.
Explanation;
-The rock cycle involves how one type of rock can be changed into another type of rock. It is the sequence of events in which rocks are formed, destroyed, altered, and reformed by geological processes.
-Crystallization isthe formation and growth of a crystalline solid from a liquid or gas.
-Erosioncondition in which the earth's surface is worn away by the action of water and wind. Compaction involves the squeezing together of layers and any water mixed in with the sediments is forced out as the layers of sediment build up, increasing the pressure on the lower layers.
Temperature is the measure of heat energy or motion of particles. Absolute zero is the temperature at which all motion of particles stops. Absolute zero is the lowest possible temperature. Absolute zero is -273 degrees on the Celsius scale. The Kelvin temperature scale is based on absolute zero. To convert from degrees Celsius to Kelvins, add 273 to the Celsius temperature.
