The majority of the world's energy is produced by burning fossil fuels. Fossil fuel combustion results in the release of carbon
Drupady [299]

The correct answer is option B, that is, the release of large amounts of greenhouse gases can change Earth's climate.

Fossil fuels refer to hydrocarbons, mainly fuel oil, coal, or natural gas, produced from the leftovers of dead animals and plants. The use of fossil fuels has allowed large-scale industrial development and hugely supplanted water-driven mills, as well as the combustion of peat or wood for heat.  

The burning of fossil fuels by humans is the biggest source of emissions of carbon dioxide that is, one of the greenhouse gases, which permits radioactive forcing and donates to global warming. One of the dreadful effects of global warming is the change in the climatic condition of Earth.

A person with prediabetes has a fasting blood glucose level of _____.
vlada-n [284]

Answer;

C. 100 - 125 mg/dL

A person with prediabetes has a fasting blood glucose level of 100-125 mg/dL.

Explanation;

-A fasting blood sugar level below 100 milligrams per deciliter (mg/dL) — 5.6 millimoles per liter (mmol/L) — is considered normal.

-A fasting blood sugar level from 100 to 125 mg/dL (5.6 to 7.0 mmol/L) is considered prediabetes. This result is sometimes called impaired fasting glucose. A fasting blood sugar level of 126 mg/dL (7.0 mmol/L) or higher indicates type 2 diabetes.

Explain the 1st and 2nd law of thermodynamics in terms of food chain, energy flow, pyramid of number and pyramid of energy
Westkost [7]

Answer:

First law of thermodynamics is the conservation of energy states that energy is not created and not destroyed but only can be stored.

Thermodynamics second law states that total entropy of a system increases from lower to higher system and some of the energy is always wasted during the work done.

In the food chain plants are the producers which accept light energy and stored in the form of chemical energy and energy flow to the herbivores and higher trophic levels in the chemical form only and no new energy is created in between the chain (Fisrt law of thermodynamics). Heat is generated during respiration by plants and animals (wasted energy) and entropy also increases with the increase in level of the pyramid of energy (Second law of thermodynamics).

A maize plant with genotype Aa Bb produces the following gametes 100 Ab 45 AB 106 aB 50 ab This tells us that the two genes are
bogdanovich [222]

Answer:

True

Explanation:

The linkage relation of two genes can be determined on the basis of calculating recombination frequency.

If the recombination frequency value is greater than 50% then the genes are not linked and if the value is less than 50% then the genes are linked.

In the given question, the  crossover gametes formed will be Ab = 100

and aB= 106.

Therefore,

\dfrac{recombinant\ progenies}{ Total\ progeny}\times 100\\\\\dfrac{100 +106}{100+106+45+50}\times 100\\\\=\dfrac{206}{301}\times 100\\\\= 68.43\%

Since the recombinant frequency value is larger than 50% therefore the genes do not show linkage.

Thus, True is the correct answer.
