Answer:
Constant variables
Explanation:
Elaina's investigation lacked the critical ingredient of constant variables which are important components of every scientific investigation. In every research, there are 3 important variables, namely:
1. Dependent variables: the actual variable to be measured during the course of investigations and whose values are dependent on another variable (independent variable) supplied by the investigators.
2. Independent variable: one of the variables that are supplied by investigators whose values are often manipulated to see the kind of changes it will cause to the dependent variable.
3. Constant variables: other variables that are neither independent nor dependent but constant for all the various experimental groups in investigations.
Answer:
The correct answer is: do not enter into a plexus and directly connect to the structures they supply.
Explanation:
<u>The </u><u>anterior rami</u><u> of the thoracic spinal nerves </u><u>from T1 to T11</u><u> give birth to the </u><u>intercostal nerves</u>, which are part of the somatic nervous system.
The intercostal nerves supply the thoracic pleura and abdominal peritoneum, and they vary from the anterior rami of the other spinal nerves in that they each take their own path without forming a plexus, <em>directly connecting to the structures they supply</em>.
The intercostal nerves are derived from the somatic nervous system, unlike the autonomic nervous system nerves that innervate the visceral pleura of the thoracic cavity. They can govern muscle contractions and give sensory information about the skin and parietal pleura as a result of this. This explains why damage to the thoracic cavity's interior wall can be felt as a severe discomfort in the damaged area. Damage to the visceral pleura causes a pain that is not localized.
Answer:
D. It can function independently
Explanation:
A. Not a haploid, the daughter cell is going to be a diploid cell, because it is a body cell, not a sex cell; they are suppose to have the same amount of chromosomes as the parent cells.
B. It will go through cytokineses ( last step of the mitosis) the cells will not be connected to parent cell and is independent (D)
C. Inside the chromosomes, no matter it is a haploid or diploid cell, it will contain DNA.
D. After going through the cell cycle, the new daughter cell produced will be a new individual and do not connect to other cells.
Answer:
Changes occurs in the environmental conditions directly affect carrying capacity of the ecosystem.
Explanation:
Carrying capacity of the ecosystem refers to the capacity of the environment which adjust plants and animals in a specific atmospheric condition. Suppose in harsh winter, the temperature of the ecosystem is very low which is unbearable for most of the plant and animal species, so very low number of plants and animals are able to live in that environment. In the ecosystem where the winter is harsh and the spring is cold, the population of living organism are more decreasing. If the ecosystem has Harsh winter, Cold spring, and Hot summer, this type of environment hold very low number of living species due to high variation in the environment.
