cancers cells with accumulation of other associated cells including tumor associated fibroblast, immune suppressive and immune modulatory, cell make a mass of cell environment called tumor microenvironment (tme).
True, the environment surrounding a tumor, including nearby blood arteries, immune cells, fibroblasts, signaling molecules, and the extracellular matrix, is known as the tumor microenvironment (TME) (ECM).
The microenvironment around the tumor and the tumor itself are intertwined and continually interacting. By generating extracellular signals, boosting tumor angiogenesis, and inducing peripheral immunological tolerance, tumors can have an impact on the milieu, whereas immune cells in the microenvironment can influence the development and spread of cancerous cells. The tumor interacts closely with the surrounding microenvironment, which is known to profoundly impact tumor progression by influencing processes that lead to tumor eradication, increased metastasis, or the establishment of dormant micrometastases.

The Adam's apple is found in the upper part of the larynx that is formed by the thyroid cartilage.
Hence, option B is correct.
Where is Adam's apple?The cartilage that wraps around the front of our larynx, or voice box, is referred to as the Adam's apple or the laryngeal prominence. The name "Adam's" apple may have originated from the biblical account of Adam and Eve, in which Adam consumed an apple, the forbidden fruit, which lodged in his throat. Our voice box and vocal cords are shielded from damage by the Adam's apple, despite the fact that it has little to do with apples.
What is the purpose of Adam's apple?The Adam's Apple's main purpose is to safeguard the vocal chords directly behind it in both sexes, independent of the angle at which it is viewed. This function is shared by the thyroid cartilage that makes up the Adam's Apple.

Explanation:
Which polysaccharide is an important component in the structure of insect and fungal cells?
Chitin is a big, structural polysaccharide made up of chains of modified glucose that serves as a structural protein. Among the invertebrates and fish, chitin is found in the exoskeletons of insects, the cell walls of fungus, and some hard structures in their exoskeletons. Chitin is only second to cellulose in terms of abundance, with cellulose being the first.
Which polysaccharides are important for structural support in animals and plants?
Polysaccharides are mostly used for one of two purposes: energy storage or structural support, depending on their structure. Starch and glycogen are both very compact polymers that are utilized to store energy in the form of carbohydrates. Animal and plant cellulose, as well as chitin, are linear polymers that provide structural support in both plants and animals, respectively.

Pine trees that are too tall or too short do not do as well as pine trees that are average in height. How is this an example of stabilizing selection?
Stabilizing selection is a condition where extreme traits have a negative outcome in the indivuals of a population, therefore the average value of the trait has the advantage. In this example, pine trees that are in the extremes of height (either tall or short) might have physiological disadvantages. On the other hand, pine trees with average height might escape this issues. For example, tall trees might have troubles with water transport, while short trees might have troubles with getting enough sunlight exposure. Average pine trees would not have disadvantages in either of the physiological examples described. With time, this trees (average height) will dominate in the population structure, whereas the other type of trees while be diminished.

What is temperature?
A physical measure that describes how hot a substance or radiation is is called temperature.
There are three different types of temperature scales: those, like the SI scale, that are defined in terms of the average translational kinetic energy per freely moving microscopic particle, like an atom, molecule, or electron, in a body; those that only rely on strictly macroscopic properties and thermodynamic principles, like Kelvin's original definition; and those that are defined by practical empirical properties of particulates rather than by theoretical principles. With a thermometer, temperature is measured. It is calibrated in a number of temperature scales that historically defined themselves using different reference points and thermometric substances.

a group of scientists wants to test the effects of decreased oxygen levels in the water on a population of albacore. what result from this experiment would show natural selection in progress?
Fish that can survive the lower oxygen levels undergo natural selection. These fish will reproduce and proliferate.
The water's lower oxygen levels will impact fish respiration. The fish may relocate to a better area with more dissolved oxygen in order to adapt to the change. However, because the fish are still the same genetically and phenotypically, there is no connection to the process of natural selection. Fish that can survive the reduced oxygen levels are selected naturally. These fish will reproduce and multiply in quantity. Fish from the next generation will be tolerant of decreased oxygen levels. This novel phenotypic denotes a modification in the genetic makeup of the fishes.
