Well you see each of the seeds have developed a special technique that allows their individual seeds to travel further and lower the probability of landing close to the tree and not getting the sunlight it needs

For the berries birds and various animals eat them carrying them away so hopefully they can get more sunlight

Helicopter seeds do the same thing except the sides themselves float away from the tree to get  a further distance.

Finally the acorn seeds of the oak tree use the same concept of the berries. Various squirrels do eat these kinds of nuts and bury them in the ground in hopes of finding them later. But due to squirrels not remembering where they buried their acorn seeds the acorns are well away from the tree and start growing. 

So you see all of these tree seeds are specially developed to help it get away from the trees. Especially so that they can grow in a much better environment than the one provided to them initially.

Which mechanoreceptor is located deeper in the skin and responds continuously to stimulation and is associated with perceiving s
Eva8 [605]

The mechanoreceptor that is located deeper in the skin and responds continuously to stimulation and is associated with perceiving stretching of the skin is called Ruffini corpuscle.

Mechanoreceptor is a sensory receptor that responds to mechanical pressure. They are connected with sensory neurons that convert this mechanical pressure into electrical signal. It is of four types-

1. Merkel corpuscles- detect pressure and roughness on skin.

2. Ruffini corpuscles- detect deep tension in skin, skin stretch.

3. Meissner corpuscles- perception of light touch and slip on skin.

4. Pacinian corpuscles or Vater-panician corpuscles- detect rapid vibrations.

When these receptors sense a stimuli they gets excited and generates an impulse that travels through the nerve cells into the brain.

Regulatory and basal transcription factors regulate transcription by binding to the promoter.A) True B) False
Licemer1 [7]

Answer:

False

Explanation:

In eukaryotes apart from RNA polymerase, the transcription of genes requires many different proteins called transcription factors. These transcription factors are important to initiate and regulate transcription.

There are two types of transcription factors regulatory and basal transcription factors. Basal transcription factors regulate transcription by binding to a gene promoter and regulatory transcription factor regulates transcription by binding to some regulatory sequences for example enhancers and silencers.  

Therefore only basal transcription factor binds to the promoter for regulating transcription. Therefore the statement is false.
