Why does the number of organisms decrease as you move up the pyramid?
Answers
The number of organisms at each level decreases relative to the level below because there is less energy available to support those organisms. The top level of an energy pyramid has the fewest organisms because it has the least amount of energy.

Explanation:
the growth activity of the cell is an important role by chromatin it is also responsible for the metabolism of cell as well as the genetic functions of cells
Answers
Chromatin plays a important role in metabolism of cell and it regulates the genetic activities of the cell as well. To create chromosomes, chromatin fibers are coiling and condensing. Numerous cellular functions, including DNA replication, transcription, DNA repair, genetic recombination, and cell division, are made possible by chromatin.
The compactification of lengthy DNA strands is chromatin's primary function. The compartment in which DNA is housed in the nucleus is much smaller than the length of the DNA itself. The DNA needs to be compressed in some way in order to fit into this compartment. The degree of DNA condensing is measured by the packing ratio. DNA is not directly packaged into the structure of chromatin in order to obtain the overall packing ratio. Instead, it has numerous organizational structures.The process of transcription involves proteins reading the genetic data encoded in DNA, converting it into RNA, and then translating the RNA into useful proteins. No transcription happens if the chromatin becomes stronger and prevents access to the read proteins. Transcription can be carried out by euchromatin, an expanded kind of chromatin. While heterochromatin, a condensed form of chromatin, is crammed too closely together for proteins to read DNA.All DNA-based processes are hindered by the way DNA is wrapped up in chromatin. Chromatin can easily change its shape and structure because of the very dynamic way that proteins and DNA are arranged. At the site of DNA damage, chromatin relaxes quickly, allowing repair proteins to connect to the damaged DNA and repair it.So, for genome replication, transcriptional silencing, DNA repair, and recombination, chromatin architecture is essential.

Marcus really wants to ask Amy for a date but begins to sweat uncontrollably and finds
it hard to speak every time he even gets near her. Choose any three psychological approaches and describe how each might explain Marcus's behavior.
Answers
Psychological approaches that describe Marcus's behavior are Psychological sweating.
Psychological sweating is a physical reaction we attempt to suppress or, in the worst case, hide. Psychological sweating occurs all over the body surface in response to emotional stimuli including stress, anxiety, and pain, although it is particularly noticeable on the palms, soles, face, and axilla. High eccrine sweat gland concentrations at various bodily areas are mostly to blame for this. Eccrine sweat glands are activated by cholinergic innervation as the main effector during times of intense psychological stress.
73% of the approximately 800 men who participated in a Men's Health study stated they wished they could sweat less. Our romantic partners would like it if we did too: 84% of the 970 women surveyed thought it was disgusting when a man dews up on a date. "Sweating without command is like your body betraying you,"
Our bodies have apocrine and eccrine sweat glands. A thicker, stickier sweat made of proteins and lipids is produced by the apocrine, which is primarily found in and around your armpits and genitalia. Your entire body is covered in eccrine, which creates a main water and salt solution. The eccrine glands were once thought to be activated simply by a need for cooling, while the apocrine were thought to be activated by mental stress.

population growth in some countries
Answers
When attempting to forecast changes in population size, demographers frequently focus on four major factors: birth rates, death rates (life expectancy), the population's starting age profile (whether it is relatively young or old to begin with), and migration.
What factors contribute to population increase in emerging nations?A decline in mortality rates, a youthful population, higher standards of living, and beliefs and behaviours that encourage high reproduction are some of the causes of the fast development.
Population is a crucial component of development since it affects both economic development and growth in both favourable and unfavourable ways.
Population growth is the increase in a population's or a dispersed group's size. Every year, an additional 83 million individuals, or 1.1% of the world's population, are added. The world's population has grown from 1 billion individuals in 1800 to 7.9 billion in 2020.
