Answer:
The correct answer would be zygote...blastocyst...embryo...fetus.
The fertilization of sperm and egg results in the formation of zygote. It receives genetic material from a male as well as a female parent.
It divides with the help of mitotic divisions and results in the formation of 2, 4, 8, and 16 celled stages.
It results in the formation of the hollow spherical ball of cells termed as a blastocyst. The cells are distributed to form the outer layer termed trophoblast and inner cell mass which gives rise to the embryo.
Trophoblast help in the implantation of the blastocyst into the uterine wall.
The cells of the embryo undergo organogenesis during different organs such as heart, brain, lungs et cetera are formed.
In humans, almost 9 weeks after the fertilization the developing embryo is considered a fetus.
The fetus development continues until birth.
An enzyme is a catalyst which means it changes the speed at which a chemical reaction occurs. It never alters the reaction in any way or changes nay chemical properties, only the speed at which it occurs and is completely absorbed in the meantime. The substrates that are reacting just have their reaction faster.
Stage 3 because the person fev1 level is go down not up
Answer:
The water treatment plant does not work properly.
Explanation:
The data from the river samples showed that there was a problem with the water treatment plant because there is high amount of pollutants are present in the river sample. The presence of pollutants in the samples shows that the water treatment plant did not work properly, if they did no pollutants are present in the river water so this presence of pollutants indicates inefficiency of water treatment plant.
Answer:
When carbon dioxide is released into the environment, typically due to human activities and respiration in animals, it gets trapped in the atmosphere. Carbon dioxide is just one greenhouse gas, but as all of the gases accumulate in the Earth, the temperature begins to rise globally. There are many implications to this, including the melting of glaciers, bleaching of corals, and increasing necessity for air conditioning systems and ventilation. When glaciers melt, they become a part of the ocean, meaning that as more glaciers begin to thaw out, the ocean will being to grow up and out. As sea levels rise, humans and animals are left with no choice but to being moving to higher points of elevation to avoid sinking. Another consequence of glacial melting is the loss of habitat for animales in many environments. Those living in glacial areas will begin to lose the snow and ice they are built to withstand. Those living near the sea or at low points of elevation will lose their habitats as it sinks deeper into the ocean. Another problem with global warming is coral bleaching. As the ocean warms up from the rising temperature, corals will being to overheat until they become ”blaeched’ whihc essentially means that they die. Lastly, global warming will create an increasing necessity for air conditioning systems and ventilators. People who do not have access to these things or cannot afford them can risk health complications. Global warming is a problem that cannot be ignore and the world needs to take more steps to plant trees and grasses that can photosynthesize the carbon dioxide into oxygen.
