<span>the one that is not a source of genetic variation is : D. Asexual reproduction
In asexual reproduction, there is no fertilization process between male and female gender. Which mean the offspring that came from asexual reproduction would be exactly the same as its parent, without any chance of genetic variation</span>
Answer:
There are several environmental factors that causes changes in the ecosystem and the population of that area such as invasive species, extreme weather, land use change, pollution and disease.
Lets take invasive species as environmental factor. Introduction of invasive species can cause a huge change in the ecosystem and affects the native population in that area. it increases the competition for food resources and decreases the survival rate of their preys.
For example: Water hyacinth (Eichhornia crassipes). It is an invasive plant species that has very bad impact of native population as well as other population, like it reduces biological diversity, oxygen loss, decreased phytoplankton productivity, eliminate plants that animals use for nesting, and alter animal communities by blocking access to the water.
Thus invasive population can affect population by reducing biodiversity, water shortages, decreasing availability and quality of key natural resources, disturb the food chain and can cause natural calamities.
Invasive species affect the resources that native species are using and that decreases the carrying capacity of the native population as it disturbs the whole food chain.
Answer:
Every living thing plays a role in the food chain and Earth's ecosystems, and the extinction of certain species, whether predators or prey, can leave behind significant impacts. ... “When a predator goes extinct, all of its prey are released from that predation pressure, and they may have big impacts on ecosystems.”
Explanation:
Answer:
<em>The correct option is B) undergo global warming at the same rate as we are seeing currently</em>
Explanation:
The Sun and the volcanoes play a great role in controlling our environment and climate even today. The quantity of the rays of the sun hitting the different parts of the Earth determines what the average weather or climate of a region would be. The volcanoes that erupt from the Earth have been a cause for global warming even today and will continue to raise the temperature of the Earth.
Ok let do the formula. V=m/d=408/11.34= 35.98 v=35.98ml so ther is 35.98 ml place in a lead hope u love my answer
