We know that there is no more more resources in our world if the resources is finished in this day the future generation will not be able to survive and will not be able to use such resources.we should prevent such resources for future generation also the future generation should get the chance to use such resources .the pollution is increasing day by day .we should control it .the main thing is that we should control the rapid population growth population growth should be controlled due to this global warming is increasing which is very dangerous leading to the declination of ozone layer due to which the harmful rays of sun may enter the earth which may cause various problems in us and cause various diseases due to which we may die.the main thing is that we should stop the population growth, we should conduct public awareness programmes and many more programmes to educate people. Population growth also creates deforestation as the number of people are increasing day by day they need more place to live ,they need more Land due to this they cut down the trees of forest and used to make houses there due to which deforestation takes place. we all know that deforestation is the process of cutting down trees. so the tree should not be cut down as it is the source of oxygen for all creatures living in this whole world and the main thing is that we should provide education to the children and the youth and many more. if we are educated we can stop such population growth. so the main thing is that we should stop population growth by giving education. Education is the only one way to stop such population growth.

True or false: male and female embryos look the same anatomically at five weeks of pregnancy.

Marizza181 [45]

The statement is true. The male and female embryos anatomically look same at five weeks of pregnancy.

In the 4th week of pregnancy the blastocysts gets implanted in the walls of uterus and develops into the placenta and then becomes an embryo. The embryo is considered starting from the point when the amniotic sac develops which is at the starting of the 5th week of pregnancy. By the 12th week of pregnancy the organs are developed such as arms and legs but the brain and spinal cord keeps developing throughout the pregnancy.

The second trimester begins at the 13th week of the pregnancy and by the 14th week the gender can be identified. So the male and female embryos are anatomically same at 5th week of the pregnancy.

This is referred to as co-evolution. It involves the reciprocal evolution of 2 species. This kind of evolution can be seen in mutualism (like the choices described above), and also predator-prey, host-parasite relationships. The term co-evolution was coined by Paul R. Ehrlich and Peter H. Raven in 1964.
