Which is one of the seven characteristics that Mendel observed in pea plants?
amid [387]

Answer:

The correct answer will be option-seed texture.

Explanation:

Gregor Mendel is known for his experiments on the pea plants by studying the traits of the plants. He observed the seven characters of the pea plants in his experiments:

1. Colour of seed albumen- which is yellow or green

2. The texture of ripe seed- which are smooth or wrinkled

3. Colour of flower- which is purple or white

4. Position of flowers (A) – which are axial or terminal

5. Length of the stem (T) – which are tall or dwarf

6. Form of ripe pods (I) – which are inflated or constricted

7. Colour of unripe pods (G) – which are green or yellow

Thus, the option-seed texture is the correct answer.

In a simple synapse, neurotransmitter chemicals are received by _______. A. the presynaptic membrane B. dendrites C. axon hilloc
artcher [175]

Answer:

In a simple synapse, neurotransmitter chemicals are received by the postsynaptic neuron.

Explanation:

The presynaptic membrane is where neurotransmitters are generated, whereas the postsynaptic membrane is where the neurotransmitter receptors have been located. The axon terminal is substantially far more structurally complicated at a neuromuscular junction.

Axon Hillock performs administrative duties by adding up all incoming signals, including inhibitory and stimulating. The action potential gets activated if this total surpasses the limiting threshold.

The neuron's cell body controls the structure of the neuron, houses its genetic material, and supplies energy for its various functions. Additionally, the dendrites' receiving information is processed by the cell body.

Dendrites gather and retain all data coming from the terminal of the axon. Dendrites get any incoming data or signals from the other neuron.

What is electrophoresis? Why does it allow scientists to separate pieces of DNA?
attashe74 [19]
Genetic fingerprinting – the analysis of DNA in order to identify the individual from which the DNA was taken to establish the genetic relatedness of individuals. It is now commonly used in forensic science (for example to identify someone from a blood sample) and to determine whether individuals of endangered species in captivity have been bred or captured from the wild. 
<span>•DNA sequencing – the determination of the precise sequence of nucleotides in a sample of DNA or even a whole genome e.g. the Human Genome Project. </span>

<span>The process of electrophoresis: </span>
<span>DNA is chopped, close to the VNTR regions, into fragments using restriction enzymes. The DNA fragments are placed on the agarose gel and a direct current is applied continuously to the gel. The DNA fragments are attracted to the anode. The shorter the fragment, the faster it moves. </span>
<span>The fragments are transferred onto an absorbent paper placed on top of the gel. The paper is heated to separate the 2 strands in each DNA molecule. Complementary probes which have a radioactive phosphorus isotope are and this pair up with the DNA strands. The paper is placed on an X-ray film and the film goes dark due to radiation emitted by the probes. Now we end up with a pattern of dark stripes on the film matching the positions reached by the fragments in the agarose gel.</span>

Transpiration is ultimately the main driver of water movement in xylem. The cohesion-tension model works like this: Transpiration (evaporation) occurs because stomata are open to allow gas exchange for photosynthesis.
