Typically gender expression is heavily influenced by societal norms, but there are some traits that have been proven to be influenced my genetic makeup of males vs females. For example, girls tend to be drawn to more artistic expression because of the cone/rod ratio of their eyes, where as males have better perception of depth and speed, so they gravitate towards faster sports and race cars. Obviously this only has partial influence. Individuals have always ventured outside gender roles and norms. Some men express are in touch with their femininity and express it despite the stigma, and some women have more ‘male inclined’ personality traits. Of course, large political, philosophical, and religious movements have more impact, such as the feminist movement in the late 1960s-70s pushing females to act less in the traditional frame.
Laurentia<span> (</span>North American Craton<span>) is a large continental </span>craton<span> that forms the ancient geological core of the </span>North American<span> continent. Many times in its past, Laurentia has been a separate </span>continent<span> as it is now in the form of North America, although originally it also included the cratonic areas of </span>Greenland<span> and also the northwestern part of </span>Scotland, known as theHebridean Terrane<span>. During other times in its past, Laurentia has been part of larger continents and </span>supercontinents<span> and itself consists of many smaller </span>terranes<span> assembled on a network of Early </span>Proterozoic orogenic<span> belts. Small </span>microcontinents<span> and oceanic islands collided with and sutured onto the ever-growing Laurentia, and together formed the stable </span>Precambriancraton seen today.
some one celled organisms reproduces by binary fission which is a process of cell division. The answer is 4.
Answer: The correct answer is D) Some energy in each trophic level is used for life processes.
Food chain represents the flow of energy through various living organisms (which lie at different trophic levels) in an ecosystem. The energy flows from one trophic level to the next and it is decreased with subsequent trophic levels.
As per the law of 10% energy transfer, only 10 % of the energy is transferred from one level to the next as the rest of the energy at every trophic level is utilized in various metabolic processes like respiration, digestion, excretion and also liberated as heat in the surrounding.
Due to this, the energy available at any trophic level is less than the previous trophic level.
