The first one, ii. Natural selection and the formation of inseticide resistant insects or antibiotic resistant bacteria.
This can be explained in very simple way. As we all know, natural selection works in a way that only that adapted living beings are going to survive through a specific environment, whether it's because they can grab their food without too much work, or even that they can adapt to the weather. When we use inseticide, we are killing lots of non-resistant insects, and what's left are those that are resistant to this inseticide, and they'll reproduce again, and again we'll go through the same process, but remember, this insect is now stronger and more resistant that before.
The second case, iii. speciation and isolation give three examples how it may occur.
Well. the allopatric speciation and isolation will happen when theres a geographic barrier between one species. This one then is divided into two diffent habitats, but what can divide than could be a mountain, a tree, a river, a rock, anything. And this could be too called as a geographic isolation, because in this new environment, species are going to develop in a different way.
Answer:
<u>Nervous System</u> could be studied as a direct result of having defective nuclei and may shed light on the cause of Parkinson .
Explanation:
<u>PASRKINSON DISEASE -:</u> Parkinson's disease is a progressive nervous system condition. Several regions of the brain are affected by the condition, especially an area called substantia nigra that regulates balance and movement.
A trembling or shaking (tremor) of the limb is often the first sign of Parkinson's disease, particularly when the body is at rest. Typically, on one side of the body, the tremor starts, usually in one hand. The head, legs , feet, and face can also be affected by tremors. Other hallmark symptoms of Parkinson's disease are rigidity or rigidity of the limbs and body, slow movement (bradykinesia) or inability to move (akinesia), and impaired balance and coordination (postural instability).
Emotions and thinking ability (cognition) can also affect Parkinson's disease. Psychiatric disorders such as depression and visual hallucinations are created by some affected persons. There is also an increased risk of developing dementia in people with Parkinson's disease, which is a loss in intellectual functions, including judgment and memory.
Hence , the answer is <u>the nervous system and other regions of brain</u> where the disease has a direct result of having a defective nuclei and may shed light on the cause of Parkinson .
Answer:
The statement that is not true for antibody staining is it can provide information about gene expression.
Explanation:
Antibody staining is important aspect of applied immunology. Antibody staining is done to determine a specific protein in a given sample.Antibody staining is done by using fluorescent dyes and also by using specific enzyme such as horse reddish peroxidase,alkaline phosphatase.
Antibody staining can be visualized with either fluorescent or radioactive labels. Antibody staining can be performed by western blotting method.Multiple antibodies can be used to stain different proteins.Antibody staining requires the hybridization of the complementary base sequence of the antibody and also the target protein to which it binds.
The plants can be classified based on their vascular and reproductive structures. The plant given in the image belongs to the Bryophyta.
<h3>What is Bryophyta?</h3>
The non-vascular plants that are a part of the plant classification are found in moist places and are small in size belongs to the Bryophyta.
The plant of this classification have a leafy multicelled plant body, that lacks true leaves, roots, and stems. They are green plants and also contains chloroplast for food synthesis.
The vascular tissue like xylem and phloem are completely absent and hence the transportation does not occur through specialized systems.
Therefore, option A. Bryophyta is the plant growing on the rock.
