Cyclins
are the chemicals that regulate the cell cycle. Cyclins work by regulating the timing
of the cell cycle in eukaryotic cell. Cyclins activates cyclin dependent
kinases (CDKs) (an enzyme that works by adding <span>negatively charged phosphate groups to other
molecules in a process called phosphorylation) by binding to it to form a cyclin-Cdk
complex. This complex then functions by acting as a signal to the cell to move
to the next cell cycle phase. At the end of the event, the cyclin is degraded, Cdk
is deactivated, therefore signaling exit from a specific phase.</span>
Answer:
Population studies look at factors for one individual species.
Explanation:
In a garden, there are multiple species of plants growing. You could study different factors of each population, which is just all the individuals of one species in an area. For example, you could study how adding fertilizer affects the growth of tomato plants. To do this, you would have some tomato plants in the garden that have fertilizer added to the soil and some that don't. At the end of a certain period of time, maybe a month, measure the plants, find the average height and compare their growth. This is just one example, but there are lots of different things you could study.
Answer:
Effect of independent variable is studied on the dependent variable or subject of the experiment.
Explanation:
The independent variables are very important in an experiment. Basically the affect of an independent variable is studied on the subject or dependent variable.
Thus, it can be said that independent variable will produce the effect on the dependent variable.
Here in this case the different types of disinfectants are the independent variable and their effect will be observed on the bacteria (subject or dependent variable)
The correct term to fill in the blank would be intensity. The intensity of exercise determines whether carbohydrates or fat is the predominant source of energy production. During high-intensity workouts, it is the fat that is used as the source of energy production while low-intensity exercises would only use the carbohydrates present for energy.
Answer:
The right answer are : mitosis, diploid cells, and identical DNA.
Explanation:
The answers "two cell divisions" and "gametes" refers to a division by meiosis which is a sexual reproduction.
Asexual reproduction or asexual reproduction is a mode of reproduction, which - as opposed to sexual reproduction - corresponds to the capacity of living organisms to multiply alone, without a partner, without involving the fusion of two gametes of opposite sexes. Asexual reproduction is observed in multicellular (animal and plant) and unicellular organisms. In botany, the term often used for the asexual multiplication of plants is vegetative multiplication. In all cases of asexual reproduction, the result is identical to the mother.
