The odd hormone insulin Cortisol
Explanation
Cortisol is known as the odd hormone because it is release when someone stressed and it interfer the brain activity by making the person feels like blank. The low cortisol level causes decrease appettite, fatigue, weightloss, different skin problem, low blood sugar and many more. The high level of cortisol causes the weight gain, acne, muscle weakness, thinning skin, flused face and other type of causes.
Among insulin, cortisol, glucagon, and calcitonin, cortisol is the 'odd one out'. It is classified as a corticosteroid, whereas the others are peptide hormones.
The odd hormone in the list of insulin, cortisol, glucagon, and calcitonin, is cortisol. While insulin, glucagon, and calcitonin are all peptide hormones, cortisol is a corticosteroid, a different type of hormone, released by the adrenal cortex in response to long-term stress. Insulin is produced by the beta cells of the pancreatic islets and regulates blood glucose levels. Glucagon, produced by alpha cells of the pancreas, also helps in regulating blood glucose levels. Calcitonin is a hormone produced by the parafollicular cells of the thyroid gland and functions to lower blood calcium levels. Though all these hormones play integral roles in the body, cortisol, as a corticosteroid, is structurally and functionally different from the others, making it the 'odd one out'.

Answer:
B. Stem cell research led to a huge leap in medical science.
Explanation:
False
Answer:
true
Explanation:
b. cytoskeleton
c. cell membrane
d. glycoproteins
The most common example of shared characteristics among different types of cells is the cell membrane. Every cell is enclosed by a cell membrane which protects the cell from its surroundings by separating the interior components from the exterior ones.
Further Explanation:
A cell membrane is permeable to selective molecules which means only particular substances can traverse the membrane. The essential molecules are allowed to enter whereas the toxic or non-essential molecules are excreted out of the cell through the cell membrane.
The phospholipids are arranged in a bilayer to form a cell membrane. It also contains the cholesterol present in between phospholipids and maintains the fluidity at different temperatures. The membrane also contains integral and peripheral proteins that help in the transport of materials and maintain the structure and shape of the cell respectively. Glycoproteins are also attached covalently to the membrane and help in cell-cell recognition, cell adhesion, and also serve as receptors for other molecules.
Apart from the cell membrane, certain cells also contain cell walls which surround the cell membrane. It is present in plants, bacteria, and fungi and prevents the over-expansion of the cell. In plants, the cell wall helps in providing turgidity to the cell and also maintains the shape and structure of the cell whereas, humans are devoid of cell walls instead they contain cell membranes.
A cytoskeleton is not a protective barrier for the cell but provides rigidity to the cell and is present in the cytoplasm of the cell. Its main function to provide rigidity to the cell and resistance against deformation by associating with other proteins and connective tissues. It also helps in the transport of material within the cytoplasm and also helps in cell signaling.

Phototropism benefits plants by allowing them to grow towards a light source, maximizing their exposure to sunlight for photosynthesis.
Phototropism is light-induced plant growth. It helps plants adapt in several ways. First, phototropism helps plants maximise sunshine exposure, which is essential for photosynthesis. Plants can maximise light absorption and photosynthetic efficiency by bending or growing towards light.
Phototropism aids plant light competition. Plants compete for light in dense vegetation or woods. Plants can maximise sunlight and minimise shadowing from neighbouring plants by growing towards light.
Phototropism helps plants maximise light energy use, growth, and survival in their ecological niche.
