Answer and Explanation:
<em>Cowbirds would be considered </em><em>an edge species</em><em>, meaning that these animals </em><em>need to live in an ecotone</em><em>. </em>
An ecotone is a transition area between two communities, or ecosystems. It is the zone of maximum interaction, and therefore with greater biological richness. The number of species is usually higher in adjacent areas, making it a meeting place for living organisms. The ecotone is usually associated with the "edge" term. The edge is the physical place where the two communities, or ecosystems meet.
The animals that live on the edge, are usually those that need two or more types of plant communities to live. In the case of the cowbird, they prefer to forage in open spaces such as grasslands, meadows, pastures and other places with short vegetation, where they can find food resources like seeds and invertebrates. They also need to lay their eggs in host nests that might be located in grasslands or forest edges over trees or shrubs where they might also roost.
The cowbirds are considered to be an edge species because they need two vegetable communities to live: open areas to feed in and forest edges to lay their eggs and roost.
Distribution of sunlight. Why is an organism's niche like a person's occupation? An organism can "make a living" and survive in its niche. a natural phenomenon that maintains Earth's temperature range.
Answer:
There is two main kind of historical sources such as:
Primary sources, it may be oral or hand-written, it is generally which is originated in the past, it can be eye witness or chronicle or observer living during a particular historical era.
Secondary sources, on the other hand is the information gathered by someone who did not actively take part in or witness a historical event, secondary sources include such as articles, magazines, popular history textbooks, etc.

Answer:
APAP x apap
Explanation:
Let us assume that the allele for wing is represented by ap.
The wild type is the strain that is common in natural condition, that is, winged condition. Hence, since both flies are homozygous, the mutant genotype is depicted as apap, while the wild type's genotype will be denoted as APAP.
The cross will be denoted as: APAP x apap
The offspring will be: APap, APap, APap and APap
Answer:
In the given case, it can be concluded that very less amount of telomerase is being produced.
Explanation:
Terminal transferase or telomerase refers to a ribonucleoprotein that supplements a telomere repeat sequence to the 3 prime terminals of telomeres. A telomere is present at each terminal of the chromosomes found in the majority of eukaryotes. It helps in safeguarding the terminals of the chromosomes from destruction or from getting combined with the adjacent chromosomes.
Telomerase has its own RNA molecule and works as a reverse transcriptase enzyme. Generally, telomerase is found active in gametes, in stem cells, and in the majority of cancer cells, however, it is generally present in low concentration or is absent in the majority of somatic cells. Thus, the decrease in the ends of the chromosomes suggests that the production of telomerase is taking place at low levels.
