-Cougar
Explanation;
-The amount of biomass decreases from the lowest trophic level to the highest. In all the ecological pyramids, producers (organisms that produce their own food) are found at the lowest trophic level. This trophic level contains the highest amount of energy.
-The organisms in the highest trophic level receives the lowest amount of energy. This is because only 10% of energy moves from one level of the food pyramid to the next. When heat comes from the sun. 90% of it is lost to the environment, 10% is consumed by the plants (primary producer). As a primary consumer ingests the plant, 90% of the original heat from the sun is lost to the environment and the primary consumer receives 10%. The secondary consumer receives 10% and 90% is lost, and so forth.
The ancestors of plants are most likely plant-like protists, which are small, unicellular, aquatic eukaryotes capable of photosynthesis. These organisms gave rise to land plants about 475 million years ago. The first land plants were simple and did not contain vascular tissue. This meant that they were not able to move food and water from one part of their structure to another. Examples of these nonvascular plants are seen in liverworts, hornworts, and mosses. All three groups are small, simple, and must live in moist environments.
The third major evolutionary development in plants occurred around 360 million years ago. Plants developed seeds. These seeds are used for reproduction and provide several advantages over plants that do not have seeds, including the ability for offspring to travel far distances from their parents, protection from the elements, and the ability to remain dormant until the time is just right to grow. Examples of plants that produce seeds are conifers, daffodils, and apple trees.
Around 420 million years ago, a great advance in plant structure evolved - vascular tissues. The two types of vascular tissue - xylem and phloem - move water and food throughout plants. This development allowed plants to expand where they could live - they no longer needed to be in only moist environments. It also allowed them to grow bigger. This adaptation was so advantageous that more than 90% of all plant species are vascular. Examples of vascular plants include ferns and horsetail.
Answer:
Option C. The age of fossils can be determined by examining the rock strata in which fossils is found.
Explanation:
Fossils are really an amazing thing in determining the evolutionary patterns. It is very much helpful in criminology also.
Answer:
Luciferin is used, for example, in reporter gene assays to study gene regulation and function where expression of the luciferin-tagged reporter is a marker to indicate successful uptake of the gene of interest in recombinant DNA techniques. Luciferase is a heat-sensitive protein that is used in studies on protein denaturation, testing the protective capacities of heat shock proteins. Luciferase is an enzyme used for bioluminescence by various organisms in nature, most famously the firefly. The scientist produces a construct in which the regulatory region of a target gene is fused with the DNA coding sequence for luciferase

Answer:
<u>Folding and faulting-</u> The process in which the layers of the Earth are displaced or moved into a different position due to some forces acted upon them, as there are different reasons due to which the folding and faulting occurs.
- The forces are so power full that they can bring the sediments of ocean to level or elevation above the sea level and can have a destructive effects for the living being. As there are various causes for folding and faulting of these layers,some of these forces are given below;
Explanation:
<u>Geological events causing the folding and faulting-</u>
<u>Tectonic Plates movement-</u> The parts of the Earth layer are always sliding over each other, and when they do they produce huge seismic waves. Which then causes the earthquakes, the folding and faulting of these layers.
<u>Volcanic eruptions : </u>It happens rarely as the number of gases and lava from inside the Earth, down from the crust move upward and erupts, producing dust in the atmosphere.
The other two geological causes are;
- <u>Intrusive igneous activity,</u>
- <u>subduction.</u>
- <u></u>
