Every time the planet reinvents itself its inhabitants adapt and evolve. Explain how Ichthyosaurs evolved from land dwelling reptiles. How long did Ichthyosaurs rule the oceans?
Answer:
Ichthyosaurs lived from Triassic to Middle Cretaceous approximately 250 million years ago until 110 million years ago
Explanation:
Ichthyosaurs evolved during the early Triassic period from land reptiles. This group was characterized by a spindle-shaped body, a shoulder girdle connected to a streamlined skull, two pairs of limbs, and digit-like bones. Moreover, Ichthyosaurs drew oxygen from the atmosphere (i.e., like marine mammals). Utatsusaurus is the oldest known Ichthyosaur species and it lived during the Lower Triassic. ln the same way to the land reptiles, Utatsusaurus had a pelvic girdle attached to the spine, and an equal length between the humerus and femur.
4 – Microwave Miracle Patrick believes that fish that eat food exposed to microwaves will become smarter and would be able to swim through a maze faster. He decides to perform an experiment by placing fish food in a microwave for 20 seconds. He has the fish swim through a maze and records the time it takes for each one to make it to the end. He feeds the special food to 10 fish and gives regular food to 10 others. After 1 week, he has the fish swim through the maze again and records the times for each. What was Patrick’s hypothesis? Which fish are in the control group? What is the independent variable? What is the dependent variable? Look at the results in the charts. What should Patrick’s conclusion be?
Answer and Explanation:
What was Patrick’s hypothesis? Fishes that are fed with food exposed to the microwave will become smarter and will swim faster. Which fish are in the control group? The ones that feed on regular food What is the independent variable? Food exposed to the microwave What is the dependent variable? The time fishes spend in swimming through the mazeWhat should Patrick’s conclusion be? You will find the results considered in the attached file.In both groups, Patrick recorded a decrease in the time spent swimming through the maze. In both groups, there were two cases in which the animal increase the swimming time. These cases could be considered as outliers. Although in general, the treated group made it in a shorter time after the treatment, when comparing values before and after Patrick can not find any real difference among groups. His results do not show any difference, hence the speed and the intelligence of the animals is not influenced by the change in food, or if it is, more experimental time is required to record significant differences.

Describe two practical uses for an artificial chemical which behaves like chlorophyll.
Chemicals like Titanium dioxide and photovoltaic cells are artificial chemicals that behave like chlorophyll.
What do you mean by Artificial chemicals?Artificial chemicals may be defined as chemicals that are synthesized by the activity of humans and their processes.
The nanoparticles of titanium dioxide have the ability to increase the light-capturing potential of a surface, while a photovoltaic cell enables sunlight to be processed into usable electricity by exciting outer shell electrons on some metals. These substances also behave naturally and initiate the reactions in the reaction center present in the chloroplast.
Therefore, Chemicals like Titanium dioxide and photovoltaic cells are artificial chemicals that behave like chlorophyll functionally.

20. What would happen to a paramecium that is placed in a jar of syrup?
Answer:
It will shrink.
Explanation:
When a solution contains more solute than the surrounding environment where ,it is located,it is said to be hyper tonic.Such a solution is of higher concentration,and therefore contains little water.
Syrup is an example of an hype tonic solution.Corn syrup as an example contains more solute in it,
Paramecium is unicellular organisms which is aquatic in habitat,therefore compare to the syrup of high solute it is hypo tonic.
Thus when placed in syrup,Paramecium loses water by osmosis,since water from the Paramecium at lower concentration would move out through the paramecium membrane ,as semipermeable membrane,into the syrup,of higher concentration
The paramecium will eventually shrink,and die,due to dehydration.

Identify the independent variable by highlighting it red. Identify the dependent variable by highlighting it yellow. 1. If I increase the temperature of the seeds, then germination will increase,
Answer:
Independent variable: temperature ; Dependent variable: germination
Explanation:
The independent variable is what is being changed in an experiment. The dependent variable is what you are measuring in an experiment.
When the independent variable is changed (in this case, temperature), it effects the dependent variable (germination).

Many villages also grow into urban/semi urban areas. This is a sign of economic growth but with the cost of environmental damage. This damages 3 things - air, water, and land. Due to urbanization, many roads are constructed. It passes through the natural habitats of other wild animals. These roadways split their habitat, and cause a reduction in their number.
The urban sprawl causes set up many factories, the use of vehicles which does air pollution. People are more prone to use vehicles which are responsible for air pollution.

Describe two examples of non-living things that have one or more of these characteristics of life.
Living organisms are distinguished from non-living things as they have the property of life.
Living organisms have important features that differs them from non-living things. For example., growth, reproduction, movement, sensitivity and death are few among many.
Growth is the unique property where a living organisms grows in size and volume.
Reproduction is another important characteristic where a living organism reproduces one of its own kind.
Living organisms move from one place to another which is not observed in non-living things.
Living organisms are sensitive to stimulus from the outer environment and respond accordingly. The stimulus can be touch, smell, temperature etc.
Living organisms have the characteristics of aging and senescence. They ultimately die.
Therefore, living organisms are different non-living things in many distinct ways.
