Answer:
The Nervous System.
Explanation:
The nervous system's job is to help in receiving information about the environment around us and generate responses to that information (a.k.a homeostasis). The nervous system can be divided into regions that are responsible for sensation (sensory functions) and for the response (motor functions).
Hope this helps!
Answer:
B
Explanation:
Answer is not A because this is not a benefit
Not C because it is also not a benefit
not D because it is not a benefit
B is the only benefit listed.
Answer:
The proportion 'p-hat' that were cyanobacteria is 0.76
Explanation:
The proportion of cyanobacteria is the relationship between the whole sample and the actual quantity of cyanobacteria found in the sample, that were not other algae. In general, proportions are written as fractions. The<em> numerator is the number of cyanobacteria in the sample, while the denominator is the total number of organisms in the sample</em>.
So, in the exposed example we know that
- The sample was composed of 50 algae
- There were two categories for the sample: algae that were cyanobacteria, and algae that were not cyanobacteria
- Algae that were cyanobacteria = 38
- Algae that were not cyanobacteria = 12
If we want to study the relationship between the sample and cyanobacteria and express it as a proportion, then we need to divide the number of cyanobacteria by the number of algae in the sample. This is
38/50 ----> Fraction expression of the relationship between cyanobacteria
and the sample
0.76 ----> Proportion of cyanobacteria in the whole sample.
The theory of evolution can be proved by the comparison of DNA genetic sequences of organisms.
<u>Explanation:</u>
The evolution can be proved by following
- Homologous organs - they are organs that have similar basic structure but perform different functions. example: Human, Bird.
- Analogous organs-they are organs that perform same function but have different structure or basic design. example: Bird and insect.
- Fossils- the remains of dead animals and plants.
Dead organisms get decomposed by microbes, due to the absence of oxygen and moisture some body parts does not decompose.
The soft parts of body gets decomposed hard parts take time to decompose and get covered by sea, at these deep levels the decomposition stops and the hard parts remain preserved called fossils.
Answer:
Because each daughter cell must contain an equal and correct amount of genetic material (DNA)
Explanation:
Mitosis and Meiosis are both types of divisions that cells undergo. They both involve the production of new daughter cells. Each cell contains the information needed by it for its life processes. This information is stored in the genetic material known as DNA.
However, when a cell divides during mitosis and meiosis, two and four new daughter cells results respectively. These daughter cells need to contain the genetic material (DNA) that stores the genetic information needed for their survival. The cell ensures that each daughter cell that will result from the process of mitosis and meiosis contains this genetic material by undergoing a process called DNA REPLICATION before the start of the divisions (mitosis and meiosis).
DNA replication is the process of doubling or duplicating the information in the DNA. Hence, at the end of the replication process, the cell contains two copies of the genetic material (DNA) which separates into the daughter cells equally during cell division (mitosis and meiosis).
Protein synthesis does not need DNA replication as it involves using the information in the genetic material (DNA) to synthesize useful products (protein).
