Answer:
the correct answer is 25%
Explanation:
the whole amount of squares is 100%. to get a homozygous dominant you must have two capital letters. only one box has two capital letters so that makes 25%
The Hershey–Chase experiment was based on a bacteriophage T2 (a virus), to that DNA is the genetic material. Bacteriophage T2 attacks bacterium and makes its copies. Based on the experiment, Hershey and Chase deduced that it is the DNA of virus enters bacteria to make virus copies. To trace viral DNA, Hershey and Chase label DNA with ³²P (radioisotope of phosphorus) because phosphorus is not present in most of the proteins.
Answer:
The roaches antennas
Explanation:
the roaches antennas sense movement from far so the antennas sense when the roach is in danger their for it moves away not towards it.
Answer:
Two terms might apply for this situation: "<u>jump dispersion</u>" and "human-assisted invasions".
Explanation:
- Dispersion: It refers to the <em>change in an organism's range or distribution area</em>. Different ecological and biogeographical processes might be involved in organisms' dispersion. The term "<u>jump dispersion</u>" refers to a <em>few individuals in a short time that can cross a barrier and occupy a new area</em>. In this situation, the establishment is not always for sure. For this to happen, they must reproduce and start a new population of a certain size that can survive to the new conditions.
- Biologic Invasions: It refers to <em>new species that establish in a new area far or out of their original distribution range</em>. Once established, these species might be <em>considered exotic or invasive, according to their reproductive rate, population growth, and interaction with native species</em>. Biologic invasions are <u><em>natural processes</em></u>, that occur in small groups of individuals that can expand to other ecosystems, and the appearing or despairing of barriers promotes their expansion. <em>But these biologic invasions have accelerated by human beings</em>, referring to this as "<u>human-assisted invasions</u>". These are the cases in which <em>men transport species from one place to the other for different uses or purposes.</em>
It is <em>very common</em> for these species to <em>scape and start new populations</em> in the <em>new area</em>, where they <em>have </em><em>less environmental pressure</em> -fewer predators, more resources, better nitches- than in their origin area, which <em>favors their establishment</em>.
The exposed situation in the example is a case of "human-assisted invasions". It might also be considered as jump dispersion (because a few individuals of the species crossed a barrier and established in a new area) but assisted by humans.
They show both the characteristics of a living and a non-living.
