The abiotic factors of a stream ecosystem involves salt, water, rocks, sediments and trash. This includes the temperature of the water, how much oxygen it contains, how acidic or basic it is, how fast or slowly, and how much sunlight penetrates the surface. A stream ecosystem is the ecosystem of a river viewed as a system operating in its natural environment, including biotic factors and abiotic factors.
Answer: false
Explanation:
we can say that the genetic map has 2 options
A …12 mu …X35 …12 mu … p2
with the fact of knowing the location of a single gene we can define the distances that the genes have, as in the previous graph, however when the "A" gene is located in the middle of the map the distance of the X35 gene will no longer be 12 mu with respect to the locus p2 gene and the X35 gene will have 36mu with the locus p2 gene
X35 … 12 mu … A …24 mu …p2
When finding the gene "A" is in one of the genetic maps, we can affirm that the answer is correct
A …12 mu … X35 …12 mu …p2
Answer:
c.
The rows of bushes
Explanation:
<em>The experimental unit in this experiment would be the rows of bushes in the field.</em>
<u>By definition, experimental units are considered physical entities that can randomly be assigned to varied treatment regimes during the course of a research.</u>
In this case, the entity that are given different treatment condition during the process of experimentation are the rows of berry bushes within one of the several fields. Half of the rows were covered with nets while the remaining half were left uncovered.
<em>The rows were given different treatments and hence, considered the experimental units in this particular experiment.</em>
The correct option is c.
<span>In a coctail party effect, participants were unable to do three of the choices but they notice specific changes when the unattended speech was played backward. An example of a cocktail party effect is when a partygoer can only focus one conversation in a room which is very loud. The other choices involves with the tone of voice but except letter d which involves the arrangement or sequence in reading.</span>
The answer is the 3rd option because adaptations can be good or bad for the population.
