The principle stating that the oldest rocks occur on the bottom of an undisturbed rock sequence is known as? The answer is superposition principle.
fishes.
A. True
B. False
Yes, brain is involved in the lineages before the evolution of fishes
A. True ✓
The statement is true. The evolution of the brain predates the evolution of fishes.
The statement that the brain evolved in the lineages before the evolution of fishes is true.
The evolution of the brain can be traced back to earlier lineages, such as invertebrates like worms and insects. These organisms had simple nervous systems that gradually evolved into more complex structures. As vertebrates evolved, the brain became more sophisticated, with different regions responsible for various functions.
Fishes, being vertebrates, have brains that are more advanced compared to invertebrates. However, they are not the first organisms to have evolved brains. The evolution of the brain predates the evolution of fishes.

Answer:
Explanation:
There are 3 different types of DNA dependent RNA polymerase. RNAP II is the main enzyme synthesizing mRNAs.
1. Signals for initiation of transcription
Promoters: there are certain specific areas on the DNA that act as starting signals for initiation process.
The DNA polymerase attaches to the promoter site on the template DNA strand.
TATA Box: upstream of the transcription start site is 5'-TATAAA-3' it is referred to as the TATA Box. It acts as a signal for the start region.
2. Initiation of Transcription. The DNA helix unwind, and the RNAP binds to the promoter site on the 5' end DNA with the help of sigma factor. RNAP reaches the appropriate site of the gene and add the first nucleotide of the mRNA.
3. Elongation of Transcription: the RNAP moves along the DNA template, new nucleotides are incorporated in the nascent mRNA, one by one, according to the base pairing rule.
4. Termination of transcription: specific signals are recognized by the termination protein (Rho factor). When it attaches to the DNA, rnap can't move further. So the enzyme dissociate from DNA and consequently newly formed RNA is released.
Answer:
Seizure is an abnormal episode of motor, sensory, autonomic, or psychic activity resulting from a sudden, abnormal, uncontrolled electrical discharge from cerebral neurons.
Explanation:
Seizure is also formally known as an epileptic seizure which it's symptoms involve uncontrolled body movements mostly with every part of the body and loss of consciousness. Epileptic seizure lasts for the maximum of two minutes before the person returns to a normal state. Bladder control however, is usually absent at this stage. Epileptic seizure can be caused by either provocation or without provocation
In provocation, the causes are very low blood sugar and blood sodium, severe fever, brain infection or concussion. Without provocation; brain injury or tumor and a stroke.
When a seizure lasts more than a maximum of two minutes, it is declared an emergency but some seizures do last for about five minutes and it is regarded as normal. There hasn't been any form of cure for epileptic seizures but there are temporary treatments which can prevent frequent seizures.
Answer:
Siezures
Explanation:
A seizure can simply be seen as a sudden, uncontrolled electrical disturbance in the brain. Seizures can cause involuntary muscular movements and behavioral changes. They can also affect levels of consciousness. Most seizures however, do not last very long. They usually last from 30 seconds to two minutes
B. They exist in fixed quantities.
C. They trap energy in the atmosphere.
D. They reflect incoming solar radiation.
C. They trap energy in the atmosphere.

greenhouse is a building that is formed from a glass structure. greenhouse is widely used by farmers whose countries have various climates. The temperature in the greenhouse will feel warm even though it was during winter. the way greenhouses work by capturing sunlight and sunlight is trapped inside the building so that the air remains warm.
The greenhouse effect is another term to describe the earth as having that effect where the sun's heat is trapped by the earth's atmosphere. gases in the atmosphere can hold heat from the sun's rays so that the sun's heat is trapped in the earth's atmosphere.
In general, the understanding of the greenhouse effect is the increase in earth's temperature caused by changes in composition, which is found in the atmosphere. That causes the sun's rays to remain on earth, and unfortunately not reflected perfectly to get out of the atmosphere.
the beginning of the greenhouse effect due to sunlight that has been reflected by various objects that exist in the layers of the earth. the process of this greenhouse effect begins when the sun emits its light in the form of ultraviolet radiation to the earth. These rays will be received by the earth and then reflected back in the form of infrared.
