The role of cyclin-dependent kinases in the cell cycle is that, they stop the cycle if something has gone wrong.
Explanation:
In Eukaryotic cells cyclin-dependent kinases are universal regulator cell. It undergoes a constant cycle and degradation known as Mitotic and G1 cyclin. When cycle dependent cycle synthesize it acts like an activating protein and then bind to cyclin-dependent kinases forming cyclin-dependent kinases complex.
Now it acts as signal to the cell to pass the next phase of cell cycle. After its cyclin gets degraded, it deactivates the cyclin-dependent kinases and from particular phase signalling stop
Answer:
The correct answer is allopatric speciation.
Explanation:
Allopatric speciation occurs when a geographical barrier comes between a species population living in the same area. This geographical barrier separates the population into two different geographical area which do not have the same condition.
So as both the separated population get different habitat environment to live so they evolve differently from each other. So natural selection and genetic drift works differently in both the population which brings genetic changes in the population and helps in creating a new species.
This would be a recessive disease.
Father is dd
Mother is Dd (has to be because one child has the disease)
Parents cross is dd x Dd which gives rise to Dd (0.5) and dd (0.5). Each time they have a child they have a 50% chance of the child having the disease. In their case, only one of their 3 children is dd. The others though are carriers!
Particles or molecules that are too big to fit through regular pores in the cell membrane, or have to big an electric charge, against the current of passive transport ( lower to higher ).
Answer: Carbohydrates like sugar and starch are readily broken down into glucose, which is the body's main energy source. Glucose can be used immediately as fuel or stored as glycogen.
