Answer:
A.
Explanation:
Synergist muscles are those muscles in body that helps or are responsible to help the same set of joint in action. They tend to serve as agonist. This muscles helps to act or produce action around a moveable joint.
An example of synergist muscle is biceps brachii that helps to perform actions in forearm flexion. a synergist can also serve as a fixator at the muscles origin.
Therefore, the correctanswer is option A.
<span>RNA, also known as Ribonucleic acid, is the molecule that is used when coding and decoding genetic information. It similar to DNA and is assembled as a chain of nucleotides.<span> </span></span>
<span>Nucleus, the control center of the cell is the organelle which intiates, enables, and manages the various simplex. compound and complex cellular activities. It also stores the DNA of the cell which is then replicated and recopied over a hundredth and thousandth times over through cell division processes. In the nucleoplasm -nucleolus, the inner part of nucleus of a cell is where the DNA to mRNA and to protein; vice-versa happens.<span> </span></span>
Answer:
Eutrophication effect
Explanation:
The term eutrophication refers to the enrichment of surface water with nutrients. This process is related to human pollution activities.
Eutrophication is the biological process that generates in water by an oversupply of nutrients or organic matter. This matter, mainly compounded with nitrogen or phosphorous, favors the multiplication of phytoplankton (microscopic plants growing on the water surface) and other aquatic plants. This overgrowth leads to an enhance in primary productivity.
Little by little begin sedimentation, caused by the death of some vegetable organisms that sink in the bottom. These sediments rich in organic matter suffer decomposition in the presence of oxygen.
When oxygen disappears, anaerobic bacteria act and produce fermentation.
On the surface, plants and phytoplankton keep growing, creating a mantle that impedes the light to reach deeper areas. The overgrowth of phytoplankton on the water surface and the fermentation processes in the bottom originate toxic compounds that damage the animals. Animals die, creating more sediments in the bottom where there are anaerobic conditions. Decomposing processes and fermentation increases, producing a bad smell.
The result of eutrophication is the <u>stratification</u> of the water mass:
- <u>First superficial layer</u>, the overgrowth of blue-green algae produce toxins and interrupt the pass of light to deeper areas. The surface then becomes warmer.
- <u>The second layer</u> might have oxygen available for the animals.
- <u>In the third layer</u>, there is no oxygen, so life is not possible for animals or plants.
- <u>In the fourth layer</u>, there are animals and plants remains in the process of sedimentation.
- <u>At the bottom</u>, there is organic matter and anaerobic bacteria that are in charge of decomposition and fermentation, also producing toxic gases and smell.
Answer:
B,D,A,C,E; 4 sets of chromosomes; 8 in a diploid cell
Explanation:
B is prophase - think pro=pre
D is metaphase - think meta=middle
A is anaphase - think ana=away
C is telophase - think telo, touching cell walls
E is cytokinesis - think C is for cell crinkling, the cytoplasm goes to its' new cells.
Answer:
Life on Earth began in the water. So when the first animals moved onto land, they had to trade their fins for limbs, and their gills for lungs, the better to adapt to their new terrestrial environment. ... In air, eyes can see much farther than they can under water.Explanation:
