Answer:

A hypothesis is a tentative, testable answer to a scientific question. Once a scientist has a scientific question she is interested in, the scientist reads up to find out what is already known on the topic. ... A hypothesis leads to one or more predictions that can be tested by experimenting

Answer:

3/8 tall, green, round

3/8 dwarf, green, round

Explanation:

The progeny which are in highest ratio represent parental plants.

Here in the given question, 3 out of 8 progeny are tall, green, round and 3 out of 8 progeny are dwarf, green, round which are the highest in number so they represent parental plants. The reason behind this is that during crossing over only two non-sister chromatids undergo crossing over while two other parental chromosomes remain intact. Out of the 4 chromosome types, 2 remain the same which will result in the same type of genotype of off-springs as of parents. So even if there is 100% chance of crossing over between non sister chromatids still only 50% will be recombinants rest of the 50% will represent parental type.

Another case may be when two genes are very near to each other then it is quite possible that the genes may not undergo crossing over at all in that case there will be no recombinants at all.

So, it simply means that parentals > recombinants or the progeny which are highest in number represent parentals.

In case of unlinked genes, parentals = recombinants. But, recombinants can never be greater than parentals.

Although animal nervous systems differ in complexity, their nerve cells are still remarkably similar. true false

Norma-Jean [14]

Answer:

TRUE

Explanation:

The nervous system only exists in animals. Neurons are the nerve cells that compose the nervous system.

The neuron´s principal function is to catch stimuli from the exterior convert them into nerve impulses that get transported to the control centers. These control centers interpret the signal and send an answer to the stimuli.

The control centers in invertebrates are ganglia, while the vertebrate´s control centers are the spinal medulla and the encephalon.

The signal transport occurs from cell to cell in inferior animals and through nerves in superior animals.

There is a progressive increase in the complexity of the nervous system. It evolved from primitive animals to the most superior ones. This evolution is especially noticeable in the development of the encephalon as the control center.

However, the basic nerve cell is very similar in all animals.
