The sun rotates faster at its equator.
A Punnett square is used to determine the __________.
A) Probable outcome of a genetic cross
B) Different forms of a gene
C) Result of a gene mutation
D) Actual outcome of a genetic cross.
<span>The question above is incomplete, the remaining part of the question is given below:
1. Since more offspring are produced
than an environment can support, organisms within a population must compete for
resources to survive.
2. Due to variations within the population, some competitors will be better
equipped for survival than others.
3. The best-equipped organisms will survive and will produce well-equipped
offspring.
4. Variations that help with survival will be passed on to future generations
and will rapidly change the whole population.
Which point is flawed as written above?
A. point 1
B. point 2
C. point 3
D. point 4</span>
ANSWER
The correct option is D.
All the options written above about Darwin's theory are quite correct with the exception of option D. Charles Darwin was the scientist who proposed the theory of evolution by mean of natural selection. Darwin submitted that, due to the scarcity of needed resources in an environment, it is only the fittest individuals in a particular population that will be able to survive and produce offspring that share their adaptability features. As this continue from generation to generation, it leads to evolution, which is defined as the changes overtime, which give rise to new species that share a common ancestors. Contrary to the point made in option D, evolution by natural selection is not a rapid process at all, it is a process that occur over a long period of time.
Answer:
Digestion
Explanation:
The breakdown of foods into forms that can be transported to cells and absorb into these cells(this process has two parts): Mechanical(breaks down large pieces of food into smaller ones) and Deglutition(swallowing).
Answer:
The cells need water to maintain their metabolic functions, the way water enters through cells membranes is by osmosis.
Explanation:
The cell membrane is a lipidic bilayer composed of phospholipids and embedded proteins. Phospholipids have the characteristic of being amphiphilic which means that possess hydrophilic and lipophilic characteristics. The most common way is by osmosis, that is a mechanism that moves water from high concentration to less concentration of water. In the cell membrane, there are is channels of proteins called aquaporins that facilitate the pass of water through the membrane. Also, as water is a very small molecule without charge, this characteristic allows passing a limit amount of water molecules through the hydrophilic characteristic of membranes.
