Explanation:
Observations allow us to collect data that we can connect back to the central problem. From this data we can start to form hypotheses (predictions on possible solutions or outcomes).
Answer:
Sister chromatids, centromere.
Explanation:
Sister chromatids are defined as the identical copies of the chromatids which is synthesized by the DNA replication of the DNA. A pair of sister chromatids called as dyad. A full set of sister chromatids synthesized during the S phase of the interphase, when in a cell all chromosome are replicated.
Centromere are defined as the specialized DNA sequence of a chromosome which helps to link a pair of sister chromatids. During the process of mitosis, and spindle fiber attached to the centromere with the help of kinetochore.
Answer:
Because volvox can photosynthesise
Explanation:
Volvox is a multicellular algae. They grow in spherical colonies.
Its cells contain chloroplasts meaning it can photosynthesise. This means it can use light energy from the sun to synthesise its own food. Therefore, it doesn't need to capture food from the environment.
The given statement is true.
The three procedures for finding population size are mark and capture, observation, and sampling. Observation is done by just watching the size of the population. Another procedure is a practice known as mark and recapture, in this the animals are first captured, marked and left in the environment.
Finally, the procedure of sampling is attained by counting the animals in a small region and then assessing.
I think the correct answer is Genetic Engineering! Hope this helps!
