The baglike structure that contains a clear fluid in which the developing embryo floats is called the Amnion.
<h3>
What is an Amnion?</h3>
The membrane that covers the embryos of reptiles, birds, and the mammals when first formed is called Amnion.
It contains amniotic fluid, which serves as an amniotic sac that provides a protective shield for the developing embryo. Together with the amnion, contains the
- chorion
- the yolk sac
- allantois
with different functions to protect the embryo.
The amniotic sac in humans is enclosed in the uterus while for birds, reptiles ,it is enclosed in a shell.

Answer: Biomass
Biomass produces gas or many sorts of waste products which are mostly used in burning and cooking. It is plant or animal material used as fuel to produce electricity or heat. Examples are wood, energy crops, and waste from forests, yards, or farms.
But the reason why it can be harmful is because biomass can produce gases like methane. Methane is a greenhouse gas which can harm the environment and reduce the ozone layer that stops harmful UV light from reaching the earth atmosphere.
Downfolds are calles synclines. B is the correct choice.
The birth rate was greater than the death rate and the immigration rate was greater than the emigration rate. Options B and D are correct.
<h3>Population growth</h3>
From the illustrated image, the world experienced an upward growth in population between 1950 and 2010.
In order for population growth to occur:
- the birth rate must exceed the death rate
- immigration must exceed emigration
Either or both of the above conditions will lead to a growth in the population.
Thus, options B and D are correct.

The correct answer is - A. Photosynthesis.
Through the process of photosynthesis, the plants manage to use the sunlight, and combining it with the nutrients that they have got through their root system, they manage to produce glucose. Then they use the glucose by converting it to energy, which is crucial for their survival and proper growth, especially for their fruits, vegetables, seeds, spores.
This process is only able to occur with enough sunlight at disposal for the plant, and even if there's very small amount of nutrients gathered from the soil or water, the plants are still able to perform this process.
