Do you see any gender difference in development of language? Give right answer I will give you brainlest rating |
|
Answer» tion:Gender can have a profound effect on how people acquire, use, and think about language. This lesson presents and discusses some of the WAYS that gender can impact how language is acquired.First of all, gender can play an important PART in language acquisition, or how young children LEARN their native language. In many societies, babies and toddlers spend more time with female caregivers, so EARLY language is often INITIALLY mimicked from a female speaker.In most language groups, young girls acquire language on average at a slightly faster rate than boys, though this tends to even out by middle childhood. Gender differences in language use appear early; girls are more likely to use language in the context of emotional relationships with others, while boys more likely to use it to describe objects and events.On average, girls also learn to read slightly earlier than boys, but this, too, evens out in middle childhood. Nonetheless, throughout the lifespan, women tend to perform slightly higher than men, on average, on tests measuring verbal acuity and performance.Hope I'm happy right. pls mark me BRAINLIEST |

What is my biomagnification explain with the help of diagram |
|
Answer» Biomagnification, also known as bioamplification or biological magnification, is any concentration of a toxin, such as pesticides, in the tissues of TOLERANT organisms at successively higher LEVELS in a food chain. This increase can occur as a result of: Persistence – where the substance cannot be broken down by environmental processes Food chain energetics – where the substance's concentration increases progressively as it moves up a food chain Low or non-existent rate of internal degradation or EXCRETION of the substance – mainly due to water-insolubility Biomagnification is the build up of toxins in a food chain. The DDT concentration is in parts per million. As the trophic level increases in a food chain, the amount of toxic build up increases. The x's REPRESENT the amount of toxic build up accumulating as the trophic level increases. Toxins build up in organism's fat and tissue. Predators accumulate higher toxins than prey. Biological magnification often refers to the process whereby certain substances such as pesticides or heavy metals work their way into lakes, rivers and the ocean, and then move up the food chain in progressively greater concentrations as they are incorporated into the diet of aquatic organisms such as zooplankton, which in turn are eaten perhaps by fish, which then may be eaten by bigger fish, large birds, animals, or humans. The substances become INCREASINGLY concentrated in tissues or internal organs as they move up the chain. Bioaccumulants are substances that increase in concentration in living organisms as they take in contaminated air, water, or food because the substances are very slowly metabolized or excreted.Explanation: |
