PRO: Quadrats work well for observing changes to whole populations over time, including distribution patterns, nesting and overall health. Some study techniques do not work with quadrats, however. For example, capture-recapture techniques that allow researchers to study individual animals do not work with quadrats because even slow-moving animals can move out of the study boundaries between sample periods.
CON: Despite the relative ease of designing quadrat studies, it is possible to introduce errors into a project. Quadrats that are too large, too small or spaced inappropriately often result in errors. For example, larger species require larger plots. Randomly spaced quadrats that are too small might miss too many individuals, resulting in under-representative estimates of population size.
Answer:
48 for the Zygote
Explanation:
A gamate(sperm) + gamate (egg)= Zygote so if the gamete as 24 its just 24+24 = 48
Answer:
Chromosomal changes occur, Induced mutations occur, and Viable errors in DNA
Explanation: I just took it :)
The answer is sea stars. Sea stars can then push their stomachs out of the body while inserting it into the prey thus the food is being digested externally. Echinoderms are having 5 or at times multiple of 5 arms. Their shell is made of calcium carbonate.
Answer:
Cell 3
Explanation:
One of the unique main characteristics that differentiates a prokaryote from a eukaryote is the absence of presence of nucleus in their cell, and where their DNA is found.
In prokaryotic cells, nucleus is absence. The DNA of prokaryote is not found in a nucleus, rather, it is contained in a region referred to as nucleoid.
Therefore, the specimen that does not have DNA in nucleus is definitely a prokaryote.
Cell 3 is a prokaryote.
