A because autotrophs create their own energy and allow other consumers to take that energy. Remember auto means itself and troph means nourish. So the plant nourishes it’s own energy

What type of ion channels in the membrane of neurons open or close in response to a neurotransmitter binding to its receptor
bagirrra123 [75]

An ion channel in the membrane of neurons which <u>open or close</u> in response to a neurotransmitter that binds to its receptor is called:  ligand-gated channel.

<h3>What is an action potential?</h3>

An action potential can be defined as a sudden, fast change in electrical (voltage) potential with respect to the transmission of an impulse to a receptor, across a cellular membrane such as:

  • A nerve cell
  • A muscle cell

<h3>What is a neuron?</h3>

A neuron is a nerve cell that is saddled with the responsibility of transmitting electrical impulses down an axon across a cellular membrane of the body of a living organism through an action potential.

In Science, a ligand-gated channel is a type of ion channel in the membrane of neurons which <u>open or close</u> in response to a neurotransmitter that binds to its receptor.

In man, hitchhiker's thumb is domiant to a straight thumb, and brown eyes is dominat to blue eyes. If a man that has a straight
pogonyaev

Answer:

25%

Explanation:

T = Hitchhiker's thumb

t = straight thumb

B = Brown eyes

b = blue eyes

The man's genotype is ttBb

The woman's genotype is Ttbb

Make a dihybrid punnett square to find the possible genotypes of the offspring

ttbb is straight thumb and blue eyes. There are 4 out of 16 genotypes with this phenotype so:

Divide 4 with 16 and multiply by 100 to get the percentage of offspring with that phenotype

4 ÷ 16 = 0.25

0.25 × 100 = 25%

Describe the Cell Cycle [Interphase, G1 phase, S phase, G2 phase]<br> describe them all please :)
Svet_ta [14]

<em>G1, S and G2 phases are all cumulatively referred to as interphase involving the growth of a cell and the replication of its DNA. Initially in G1 phase, the cell grows physically and increases the volume of both protein and organelles. In S phase, the cell copies its DNA to produce two sister chromatids and replicates its nucleosomes. Finally, G2 phase involves further cell growth and organisation of cellular contents. The S phase of a cell cycle occurs during interphase, before mitosis or meiosis, and is responsible for the synthesis or replication of DNA. In this way, the genetic material of a cell is doubled before it enters mitosis or meiosis, allowing there to be enough DNA to be split into daughter cells. The S phase only begins when the cell has passed the G1 checkpoint and has grown enough to contain double the DNA. S phase is halted by a protein called p16 until this happens.</em>
