Sediments on the surface of oceans act as a document of history for the earth. It is a large scale extended collection for a dead and decaying animal, rock, and sand which can help scientist to learn about ancient climates. It tells a scientist about;

1. Drop-stones and ice-rafted ruins act signification of glacial movement.

2. Pollen records in oceanic rocks can give evidence of warmth and aridity of the adjoining areas.

3. Several rock types such as shallow-water limestone are representative of tropic environments, moreover the fossils of coral reefs, also give an implication of past local climate.

4. Several organic particles can be applied to measure water temperature, at least for the moderately recent geological happenings.

vampirchik [111]

Answer:

oropharynx

Explanation:

The pharynx, which is sometimes referred to as the throat, is the cone-shaped muscular tube that links the oral and nasal cavity to the larynx and oesophagus. The pharynx, which serves as a passage for movement of food from the mouth to the esophagus and also as an airway, is divided into three parts, namely: the nasopharynx, oropharynx, and laryngopharynx.

The oropharynx is the part that receives both air and food. It is the middle part of the pharynx (throat) found at the back of the soft palate of the mouth and also underneath the nasopharynx.

Mendel used
padilas [110]
Experiments in general are more reliable when a greater sample size is used. When using a small sample size, a mistake or fluke can greatly effect the outcome of the experiment. With a large sample size, there is more data to understand averages and deviations to the average data. The average will likely be more accurate with more data, which would make his sample size more reliable.

Which of the following kinds of cells preform basic functions such as obtaining energy from food?
strojnjashka [21]

Plant cells, but not animal cells

Animal cells, but not plant cells

Both plant cells and animal cells

Neither animal cells nor plant cells

Answer:

Both plant cells and animal cells

Explanation:

The process where the energy locked up in food is extracted take place in both plants and animal cells.This process is called Cellular respiration.It is the process of combining inhaled and diffused oxygen in the blood with assimilated food substances (glucose,amino acids,fatty acids and glycerol) to produce energy.

In both cells it takes place in the the cytoplasm and mitochondrial.

It begins with Glycolysis, followed by Krebs's Cycle..These two steps gives certain of ATPs to these cells

.However,the largest amount of ATPs is synthesized during oxidative phosphorylation  for maximum of energy to be produced.This process involved the chemiosmosis where protons were diffused into the intramembranes by the proton pump (PMF) and diffused back into the matrix of the mitochondria to generate the electrochemical gradients.

The electrochemical gradients generate the energy for enzymes ATPase synthase needed for phosphorylation of ADP with Pi to give ATPs.

The oxygen act act the final electron acceptor.
