What are the answer cheseis
Answer:
In prokaryotes (organisms without a nuclear membrane), DNA undergoes replication and transcription and RNA undergoes translation in an undivided compartment. All three processes can occur simultaneously.
In eukaryotes (organisms with a nuclear membrane), DNA undergoes replication and transcription in the nucleus, and proteins are made in the cytoplasm. RNA must therefore travel across the nuclear membrane before it undergoes translation. This means that transcription and translation are physically separated. The primary transcript, heterogeneous nuclear RNA (hnRNA), undergoes extensive post-transcriptional processing to make a messenger RNA (mRNA)molecule that can pass through the nuclear membrane.
Explanation:
Mass does<span> not </span>affect<span> the </span>acceleration<span> due to gravity in any measurable way. The two quantities are independent of one another. Light </span>objects<span> accelerate more slowly than heavy </span>objects<span> only when forces other than gravity are also at work. When this happens, an </span>object<span> may be falling, but it is not in free fall.
Mass does matter when pointed in a downward angle, like if you have a metal toy car racing down a large peice of wood at a downward angle. If you had a plasitic car aong side it to measure which would go faster the metal car will reach the bottom quicker, gravity weighs down things :)</span>
Answer:
3.)A person shivering when their body temperature is low.
7.)Ants moving within their mounds depending upon the time of day
1-A plant bending toward a light source.
.-Iguanas laying in the sunlight if their body temperature is low.
.-A unicellular organism beating microscopic hairs to escape a chemical pollutant in its environment
.-Birds migrating when seasons change.
The maintenance of relatively constant internal environment of an organism is called Homeostasis.It is an automatic regulations of the body systems and organs controlled by the brain and some receptors, specific for certain body fluctuations.E.g Thermoreceptors Chemoreceptors etc.
The fluctuations in the body internal systems must be controlled within a narrow limits, for existence of living organism.The brain receives inputs from the receptors, and the outputs from the brain ensures the homeostatic control.
The above examples are typical homeostatic responses by the organisms involved, because the inputs from the receptors send signals to the brain ,and the organisms responded to these with the example above.
Explanation:
Firstly they are not membranes and they are villi's which increase the surface area during digestion
