<h2>Only 3rd statement is false </h2>

Explanation:

  1. CDK's confer target specificity to cyclin/CDK activity-This statement is true because in the cell cycle cyclin-dependent kinases (Cdks) process signals that lead to cell division
  2. Cyclins activate CDKs-This statement is true because cyclin is the regulatory subunit which binds to CDKs and activate them
  3. Only one cyclin is required per cell cycle-This statement is false because there are many types of cyclins per cell cycle;for example G1 cyclins(Cyclin D and E),S phase cyclins(Cyclin A) and mitotic cyclin(Cyclin B)
  4. CDKs are destroyed by the ubiquitination apparatus-This statement is true because degradation of CDKs occurs through polyubiquitination
  5. The concentration of a CDK changes less than a cyclin during a cell cycle-This statement is true because during the cell division cyclins are periodically synthesised whereas CDKs concentration remains constant

Nuclear envelope forms at each pole spindle dissolves chromosomes uncoil is called
zavuch27 [327]

Answer:

The moment where the nuclear envelope forms at each pole spindle dissolves chromosomes uncoil is called Telophase.

Explanation:

In the eukaryotic cell, telophase is the final stage in meiosis and mitosis. In this step, the effects of prophase and prometaphase are reversed. This is the forth stage and a nuclear envelope forms at each pole. The spindle dissolves and the chromosomes uncoil, cytokinesis begins. The cell continues to enlogate.

Suppose a drug is developed that blocks K+ leakage channels. The drug prevents ions from passing through those channels. If this
Sav [38]

Answer: 1. The resting membrane potential would become less negative (more positive).

Explanation:

Resting membrane potential is a voltage carried by a resting (non-signaling) neuron, or called as resting potential, across its membrane.  The resting potential is determined by ion concentration gradients across the membrane, and the permeability of the membrane to each ion form.  

In a resting brain, there are gradients of concentration across the Na+ and K+ membranes. Forces shift their gradients down through channels, resulting in a separation of charges that provides the potential for rest. The membrane is much more permeable to K+ than to Na+, so the resting potential is similar to K+'s potential for equilibrium.

Hence, the correct option is 1. The resting membrane potential would become less negative (more positive).

assuming that your producer level has 3,500,000 kilocalories of energy/area, use the rule 10 percent in energy transfer to calcu
Shtirlitz [24]

Answer: I think you have to divide each level by 10 so the first level will stay the same and the rest go like this

3,500,000 divided by 10 equals 350,000

350,000 divided by 10 equals 35,000

and 35,000 divided by 10 equals 3,500
