What are two different ways a plant could control turgor pressure?

Biology

The ways that a plant could control turgor pressure is by pumping ions and Opening and closing of stomates to control evaporation from leaves.  Of course, It requires water to do so. And for the uptake of water from its surroundings, a cell must keep its internal fluid or the cell sap at a higher solute concentration or lower water potential.

<span>Turgor pressure (hydrostatic pressure) of the plant can be described as the force within the cell that pushes the plasma membrane against the cell wall. Turgor pressure within plant cells is regulated by osmosis (travel of the water from an area with a low concentration of solutes, to one with a higher-solute concentration). There are two mechanisms for the regulation of turgor pressure.</span>
<span>1. The semipermeable membrane, which only allows some solutes to travel in and out of the cell. Also, it can maintain a small amount of pressure.
</span> <span>2. Transpiration by opening and closing of stomates to control evaporation from leaves<span>, which results in water loss and decreases turgidity in cells.</span></span>

Which of the following does NOT describe the macronucleus of a paramecium?
ololo11 [35]
D. The macronucleus does not disintegrate during conjugation.

The macronucleus contains the working copies of genes needed to support an enormous cell. It is formed by a division of the fused diploid nucleus after conjugation followed by multiple rounds of internal gene replication which does not occurs in the micronucleus.

maksim [4K]
The correct answer is speciation.
Speciation is the term that describes the evolutionary process causing populations to evolve into different species. There are four different types of speciation: allopatric, peripatric, parapatric and sympatric. In this case, the process described is an allopatric speciation, the most common of these four types. Allopatric speciation happens when populations are geographically separated, an event that obstructs the gene flow. Since the gene flow stops, the populations evolve in response to the different environments that they live in.

What is medulla oblongata ?

  • Medulla oblongata, also called medulla, the lowest part of the brain and the lowest portion of the brainstem.
  • The medulla oblongata is connected by the pons to the midbrain and is continuous posteriorly with the spinal cord, with which it merges at the opening (foramen magnum) at the base of the skull.
  • The medulla oblongata plays a critical role in transmitting signals between the spinal cord and the higher parts of the brain and in controlling autonomic activities, such as heartbeat and respiration
  • The medulla is divided into two main parts: the ventral medulla (the frontal portion) and the dorsal medulla (the rear portion; also known as the tegmentum).
  • The ventral medulla contains a pair of triangular structures called pyramids, within which lie the pyramidal tracts.
  • The pyramidal tracts are made up of the corticospinal tract (running from the cerebral cortex to the spinal cord) and the corticobulbar tract (running from the motor cortex of the frontal lobe to the cranial nerves in the brainstem)

How would a mistake in transcribing the DNA message affect your ability to catch the killer?
mel-nik [20]

Answer: When the DNA collected on the crime scene is being analysed in the forensic lab, the results will be inconclusive, because error in DNA transcription, particularly in mRNA encoding leads to inheritable phenotype change by reprogramming the transcriptional network, without changing the DNA. Transcription errors are brief with no long-term consequences. Due to mRNA being short-lived and the erroneous proteins are degraded. A decrease in transcription accuracy triggers cellular identity change.

Explanation: This is called epimutation, a heritable modification that results in the change of gene expression, but not the DNA sequence. Epimutation is not associated with DNA mutation, but is associated with the loss or gain of DNA methylation or other heritable changes of the chromatin.
