Answer: Option A  

Explanation:  

Petrification can be defined as the biological phenomenon in which the organic materials like shell, bones and plants becomes a fossil by replacing the the original organic material and filling of the original space by minerals.  

All the living organism undergoes this process. The dead and decaying organism dies and then petrifies to form fossil.

Hence, the correct answer is option A

Petrification happens when substances or objects get replaced with mineral molecules, so that would be the first answer; shell bone or wood is replaced with dissolved minerals.

in a vegetable garden 45 bean plants have been eaten by deer 5 are untouched what is the frequency of bean plants in the garden
alex41 [277]

Answer:

90%

Explanation:

Frequency of bean plants in the garden that have been eaten can be calculated as the total number of bean plants eaten divided by the total number of all bean plants in the garden.

Given that:

Number of bean plants eaten = 45; number of bean plants uneaten = 5

Total number of bean plants in the garden = 45 + 5 = 50

Therefore, frequency of bean plants in the garden that have been eaten = 45/50 = 0.9 = 90%

Frequency of bean plants eaten in the garden by the deer = 90%

1. Give TWO examples of how the location of terrestrial biomes and how they are determined by both biotic and abiotic factors.
Sauron [17]

Answer No 1:

The terrestrial biomes depend on the type of land on which the biome will be formed.

Two of the examples of terrestrial biomes are:

  • Desert biome: A desert biome will be formed in areas where there is little to no water. The biotic components of such a biome are adapted to live in harsh conditions. The plants are adapted to use little water and animals can survive with little water and can also store water in their bodies.

  • Tundra: Plants and animals in this biome are adapted to survive in extreme cold temperatures. Animals, like the polar bears, have fur on their bodies which keep the heat insulated in them.

Answer No 2:

Both the biotic and abiotic components of a biome are dependent on each other.

Some of the ways by which abiotic factors might be affecting the biotic factors of an aquatic ecosystem are:

Temperature: More number of organisms will be able to survive in the rivers when the temperatures are moderate. During extreme conditions, lesser number of aquatic species will be able to survive.

Sunlight: There will be more aquatic plants in the area of the ocean which receives more sunlight. These plants will  be  a source of food for many aquatic animals. Hence, there will be more diversity in areas of the river which receive more sunlight.

This indicated that Photosynthesis was occurring.

Photosynthesis- Green plants employ a process called photosynthesis to produce their own sustenance. Life on Earth depends on photosynthesis. Without it, there wouldn't be any green vegetation, and there wouldn't be any creatures either. Interactive. Sunlight, <u>chlorophyll</u>, water, and carbon dioxide gas are necessary for photosynthesis.

Chlorophyll- Chlorophyll is a pigment found in certain living creatures and all green plants. It is necessary for the process of photosynthesis, which turns light energy into chemical energy. The pigment chlorophyll is what gives plants their green color.

Pigment- A chemical that may be found in animal or plant tissue and gives off a distinctive color, such hemoglobin in red blood or chlorophyll in green plants.
