Answer:
The blood pH will increase.
Explanation:
Antacids are the chemicals that works against the acids that produced in our stomach. Antacids are generally used to treat the excessive acidity of the stomach.
The intake of excessive carbonate base causes the release of gastric acid secretion in the stomach. Hence, the blood pH increases due to the presence of H + ions in the blood.
Thus, the blood pH will increase.
Answer:
The food chain showing seven organisms can be drawn as follows:
Plants → grasshoppers → mice → frog → snakes→ eagles → decomposers
The plants are the primary source of food in a food chain or a food web. The animals which feed on plants will be termed as herbivores or primary consumers like the grasshopper. The organisms feeding on primary consumers will be the secondary consumers like mice.
An energy pyramid for three of the organisms can be shown as follows:
mice (10 kilocalories)
↑
Grasshoppers (100 kilocalories)
↑
Plants ( 1000 kilocalories)
As the energy pyramid shows, only about 10% of the energy travels from one trophic level to another.
Explanation:
<span>Some of the things that would make the experiment invalid would be, if there was a variation in the behavior of the class with respect to food - for example, if some people ate their breakfast earlier than the others. This then would mean that some students would have already digested their breakfast during the morning classes and the others would still be digesting. </span>
Answer:
Cells divide and reproduce in two ways, mitosis and meiosis. Mitosis results in two identical daughter cells, whereas meiosis results in four sex cells. Below we highlight the keys differences and similarities between the two types of cell division.
Mitosis is a form of eukaryotic cell division that produces two daughter cells with the same genetic component as the parent cell. Chromosomes replicated during the S phase are divided in such a way as to ensure that each daughter cell receives a copy of every chromosome. In actively dividing animal cells, the whole process takes about one hour.
Meiosis is the form of eukaryotic cell division that produces haploid sex cells or gametes (which contain a single copy of each chromosome) from diploid cells (which contain two copies of each chromosome). The process takes the form of one DNA replication followed by two successive nuclear and cellular divisions (Meiosis I and Meiosis II). As in mitosis, meiosis is preceded by a process of DNA replication that converts each chromosome into two sister chromatids.
The role of an enzyme is to B change the activation energy of the reaction. Specifically, they increase the general speed of all reactions and are made of proteins.
