Its ending of winter in August in Sydney.
<u>Explanation:</u>
Australia is one of the 7 continents that is present in earth. It’s located in Southern hemisphere. So due to the revolution of earth, when northern hemisphere comes closer to sun, southern hemisphere goes away and vice versa. So when it’s summer in northern hemisphere, it’s winter in Southern hemisphere.
In August, in Northern hemisphere, the summer ends and winter starts setting in. Thus in Southern hemisphere, or in Sydney, there’s ending of winter and the starting of summer there.
B. it had to have been in a warm area and then moved there by plate tectonics over time due to the warm-climate plant fossils found there
Explanation:
One evidence that suggests that ancient Antarctica was situated in a different location from today is seen in the warm-climate fossils plants found there.
- Antarctica today occupies the southern polar region of the earth.
- It the coldest region on earth with very extreme of cold.
- From the theory of continental drift proposed as subset of plate tectonics, the continent Antarctica was once a landmass in a tropical region with lush green plants.
- Fossils of palm fronds and seeds of tropical plant species have been unearthed in some sedimentary layers in the continent.
- The scientific explanation to this is that the continent was once up above it's current position.

The roots of eh gymnosperms are long and deep, with the advantage to gather deep water. Thus, option D is correct.
Roots are the important network of tissues that gathers the water and essential nutrients from the soil and allow growth.
<h3>What type of roots are in Gymnosperms?</h3>
The gymnosperms are advanced plants with bare seeds. The roots system in the gymnosperms is the taproot system.
The root system in the gymnosperm is the long deep roots that are immersed deep inside the soil.
Thus, the advantage of roots to gymnosperms arises from the deep root for gathering water below the surface. Thus, option D is correct.

Increasing the light intensity increases the rate of photosynthesis, until some other factor - a limiting factor - becomes in short supply. At very high light intensities, photosynthesis is slowed and then inhibited, but these light intensities do not occur in nature.
