In photosynthesis, light energy is harvested and used to generate
molecules of ___
which contain high amounts of chemical
energy.

Answer: Measurement of the amount of waste produced.

Explanation:

Measurement of the amount of waste produced is the independent variable for a controlled experiment in this case. Therefore, the correct statement is option B.

The independent variable is the variable that can be changed in a controlled experiment. In this case, the researcher can manipulate the amount of waste produced followed by observation of its effect on the ecological footprint.

The researcher can manipulate the amount of waste by changing the factors such as the type of waste produced, recycling facilities available, etc. under controlled conditions.

Once the independent variable is manipulated, the researcher can observe its effect on the dependent variable. In this case, the ecological footprint of the individual is a dependent variable. The dependent variable is the variable that can be affected by the independent variable and is measurable.

Therefore, the measurement of the amount of waste produced is the independent variable for a controlled experiment.

Answer:

At each higher level of consumption, the amount of toxin is magnified.

Explanation:

Those predators all eat smaller secondary consumers, and those secondary consumers eat the primary consumers, which a lot of the times are exposed to DDT. For example bugs are often the primary target for DDT, once those bugs are exposed to the DDT they carry it in/with them. When a fish eats the bug, that fish is now exposed to the DDT. When the fish is caught and eaten by an eagle that eagle and its young are now being exposed to DDT. The DDT might not effect the full grown eagle for its lifetime but it does effect its young.

Predatory animals like owls are often threatened in habitats that have a more complex chemical composition due to the biomagnification and bioaccumulation of toxic substances in their bodies.

There are producers, consumers ,and decomposers are present in the food chain. The food chain starts with the producers, such as terrestrial plants, phytoplankton, herbs, etc.

The producer makes the food by photosynthesis, and this food is taken by the consumer. From the primary consumer/ herbivore, the energy and nutrients pass to the secondary consumer, and then to the tertiary consumer. After the deaths of the producer and consumer, they are decomposed by the decomposer.

If in an ecosystem there are chemicals present, then the chemicals attach to the plants' leaves and are consumed by the herbivores. The carnivores feed on herbivores, and the toxic material present in the herbivores is passed down to the carnivores. As a result, the toxic chemicals in the carnivores accumulate over time. This is called biomagnification. The owl is a carnivore that feeds upon the insect, so the magnification is seen.

Hence, the owl is threatened due to biomagnification.

Answer:

C. a distant luminous object travels rapidly away from an observer.

Explanation:

Option C is the correct answer.

Redshift is actually observed when a distant luminous object travels rapidly away from an observer.

In redshift, observers actually see an object that is travelling away from them and it has longer wavelength. The opposite is the blueshift where observers see a light traveling towards them  and shifted to shorter wavelength.

In astronomy, redshift takes place when the object's visible light travels towards the red end of the spectrum.

A red shift is observed when a luminous object is moving rapidly away from the observer.

A red shift refers to a shift to a longer wavelength. It is observed when a luminous object is moving away from an observer. This is different from a blue shift where the luminous object is moving towards the observer.

Hence, in astronomy, a red shift is observed when a luminous object is moving rapidly away from the observer.

Answer:A cladogram may be a chart utilized to speak to a speculative relationship between bunches of creatures, called a phylogeny.

Explanation:

Answer:

If the average temperatures of temperate forests fell by about 25ºC during the period of 1500 years, the natural modification of the animals that would be favored would be that which allows an adaptation to the new climatic circumstances by the fauna of said forests, that is , to the notable drop in temperature. Thus, for example, animals would develop more voluminous furs, which would allow them to heat their bodies in a better way.

Gene flow is the timer for the increase in genetic variation that occurs when animals move into another population.

Gene flow is the transfer of genetic material from one population to another. If the rate of gene flow is high enough, then two populations will have equivalent allele frequencies.

Gene flow is the movement of genes into or out of a population. Such movement may be due to migration of individual organisms that reproduce in their new populations, or to the movement of gametes (e.g., as a consequence of pollen transfer among plants).

Gene flow is the transfer of genetic material from one population to another. Gene flow can take place between two populations of the same species through migration, and is mediated by reproduction and vertical gene transfer from parent to offspring.

Answer:

Nuclei of gametes and somatic cells are similar to each other in its function.

Explanation:

The conclusion of the data is that the nuclei of gametes and somatic cells are similar to each other because both performs same function in the cell i.e. regulates activities of the cell. The nuclei of somatic or skin cells work efficiently in the egg cells due to similar composition and structure of nuclei that performs similar function in the cell so that's why injection of skin cell's nuclei into egg cells results the same i.e. formation of tadpoles.

A chemical company produced a genetically engineered potato called the New Leaf Superior, and one possible disadvantage of growing this type of potato is the chemical might be harmful to humans when they eat the potato that is in Option C.

Genetically engineered foods are foods that have been artificially altered to be different from the wild type of the variety and have the potential to provide a variety of benefits, such as increased crop yields and pest resistance. They are also a great help in meeting the growing demand for food, but the ethics of genetically engineered foods are still in debate.
