Answer:
Ans1 Not only does it contain the oxygen we need to live, but it also protects us from harmful ultraviolet solar radiation. It creates the pressure without which liquid water couldn't exist on our planet's surface. And it warms our planet and keeps temperatures habitable for our living Earth
Ans.2 The carbon dioxide theory states that, as the amount of carbon dioxide increases, the atmosphere becomes opaque over a larger frequency interval; the outgoing radiation is trapped more effectively near the Earth's surface and the temperature rises.

Earth is a beautiful planet that revolves around a star called Sun, which is located in one of the arms of our Milky Way Galaxy. It is the only planet known to support life in the Solar System. Humans are the most intelligent civilization on this planet. It's blue when seen from space. Recently, Earth 29 spacecraft was able to land on this planet, after 28 unsuccessful landings of Earth series of spacecrafts. We were able to learn many things about humans, most important of these was the most spoken language of them, which they call English. According to experts, humans are not yet ready to know about our existence. It can take about 1 or 2 more centuries, until they are ready to know about us.

Female reproductive organs consist of the ovary which generates the ovum a female gamete that is responsible for fertilization.
Males consist of consisting of tests that generate the sperm male gamete which is responsible for fertilization.
Both organs are necessary to produce a gamete for fertilization which develops a zygote and makes the baby is developing of the cells.
Therefore, for producing sex cells ovaries and testes are important organs, hence option c is correct.

A hurricane passes through the Gulf of Mexico and destroys many of the coastal regions of Northwest Florida. Which of the following is a likely impact of this catastrophic event on biodiversity?
Group of answer choices
Species brought in by the storm surge will displace species native to the coastal wetlands.
Excessive salt from the storm surge will flood coastal wetlands and raise salinity to intolerant levels for the local species, causing a decrease in biodiversity
Coastal wetlands will grow exponentially with the input of nutrients from storm upwelling and biodiversity will increase in these areas.
Species reliant on coastal wetlands for survival may experience a decline in population due to loss of habitat.
Answer:
Species reliant on coastal wetlands for survival may experience a decline in population due to loss of habitat.
Explanation:
A hurricane destroys many coastal regions of Northwest Florida which leads to the loss of habitat of many species that lives on the coastal region of Northwest Florida. This hurricane destroy the habitat that leads to decrease in population of organisms that lives in that coastal region so we can conclude that the population of organisms decreases due to this hurricane.

living and nonliving things interact in _______.
A. cells
B. species
C. organisms
D. ecosystems
Elements such as carbon can move through the environment and organisms in a cycle because living and nonliving things interact in ecosystem. The correct option is D.
What is an ecosystem?An ecosystem is made up of all the organisms and the physical environment in which they live.
These biotic and abiotic elements are linked by nutrient cycles and energy flows. Photosynthesis introduces energy into the system, which is then incorporated into plant tissue.
Healthy ecosystems clean even our own water, purify our air, keep our soil in good condition, regulate the climate, recycle nutrients, and provide us with food.
They supply raw materials and resources for pharmaceuticals and other uses. They are the foundation of all civilization and the lifeblood of our economies.
Because living and nonliving things interact in an ecosystem, elements such as carbon can move through the environment and organisms in a cycle.
Thus, the correct option is D.

3. Which type of fossilization occurs when a sticky substance from plants captures and preserves an organism?
Permineralization
Mold

Tar
Answer:
Fossil Resin
Explanation:
The type of fossilization that occurs when a sticky substance from plants captures and preserves an organism is Fossil Resin.
Fossil resins are usually trapped in the resin that some trees and plants including amber, copal, and retinite exude.
Amber is also a fossil resin. Under the right conditions, resins polymerize and turn into copal. Copal matures into amber after several million years.
