One of the most abiotic factor that may affect humans directly is waster availability because with out water we can get dehydrated and die.
Answer:
Triassic Period (252 to 201 million years ago)
All continents during the Triassic Period were part of a single land mass called Pangaea. This meant that differences between animals or plants found in different areas were minor.
The climate was relatively hot and dry, and much of the land was covered with large deserts. Unlike today, there were no polar ice caps.
It was in this environment that the reptiles known as dinosaurs first evolved. Reptiles tend to flourish in hot climates because their skin is less porous than, for example, mammal skin, so it loses less water in the heat. Reptile kidneys are also better at conserving water.
Yes its called photosynthesis, its how they make there own food. <span />
Answer:
In eukaryotic cells you find core and proximal promoters.
Promotors are specific DNA sequences where transcription factors (proteins) and RNA polymerase binds to initiate transcription. Promotors are located upstream the coding sequence
Core promoters are where RNA polymersae binds and proximal promoters are where transcription factors bind.
Enhancer elements are DNA sequences where transcription factors (proteins) bind to increase the rate of expresion of an specific gene. Enhancers can be located either upstream, downstream or thousands of nucleotids away from the of the coding region.
Explanation:
Promoters and enhancer are key elements for controling gene regulation. Transcription begins when chromatin rearranges from a condensed state to a accesible state, this allow to transcrition factors and RNA polymerase to bind specif DNA sequences (promotors). Proteins bind to enhancers , this complex develops a DNA loop, so that the protein that is bound to the enhancer interacts with the RNA polymersase. When this interaction is made, the activity of the RNA polymerase is increased.
Answer:
Names are universal
Explanation:
Current naming system that is followed all over the world is called binomial nomenclature. There are many significant and useful features of this classification system however one of the most important feature is the universality of the name.
The scientific names of organism are usually Latin derived and composed of two parts among which first is genus name and second is specie name.
For example<u>: Rosa indica</u> is the scientific name of Rose and it is same all over the world. Unlike common names we dont have to search for name to make others understand which flower we are talking about because if we know scientific name anyone can understand it.
Hope it help!
