Biology

Feliz [49]3 years ago
5 0

Answer:

A. The extension of Mendelian genetics comprises the codominance, incomplete dominance, polygenic inheritance, multiple alleles, lethal genes, sex lined genes, gene mapping, and others.  

B. The phenomenon of incomplete dominance takes place when of both the recessive and dominant forms, no one gets expressed in the F1 generation, however, an intermediate expression is witnessed. For example, crossing red flower with the white one generates pink flowers.  

On the other hand, in codominance, both the alleles get expressed, like in the blood group AB. The association of genes results in epistasis, it changes the normal dihybrid phenotypic ratio, that is, 9: 3: 3: 1 to 12: 3: 1. The genes, which suppress the others are called epistatic, while the ones, which get suppressed are known as hypostatic.

1) How would planting trees most affect the water cycle?. A) decrease in evaporation. B) increase in transpiration. C) movement
77julia77 [94]
<span>1. Planting trees INCREASES THE TRANSPIRATION. The correct option is B. Transpiration is the process by which plants lose water through their openings to the atmosphere. If the number of planted trees increases, the level of transpiration will also increases.
2. INFILTRATION is the process by which water enter deep into the earth surface. Infiltration is a measure of the ability of the soil to allow the water to enter and move through the soil profile.</span>

Answer: III - Dark heat absorbing coloration of a reptile

Explanation:

Reptile possessing a skin pigment that enables them to absorb heat from the environment.

Note that the Light coloration of a peppered moth is due to evading predation NOT acquiring energy.

Also, the FANGS AND CLAWS of lion are adaptations for predation NOT acquiring energy.

So, the "dark heat absorbing coloration of a reptile" is the answer

The Changing Forms of Carbon
Tom [10]

Carbon is found in different forms on the Earth. It is found as carbon dioxide in the atmosphere, as carbonate and bicarbonate salts in various minerals, as well as it occurs in the elemental form of diamonds and graphite. All biotic factors are based on carbon-containing molecules like carbohydrates, proteins, fats, nucleic acids and vitamins. Carbon is incorporated into life-forms through photosynthesis which is performed in the presence of sunlight by all life-forms that contain chlorophyll. Photosynthesis converts CO2 from the atmosphere or dissolved in water into glucose molecules. These molecules are either converted into other substances or used to provide energy for the synthesis of other biologically important molecules.

The use of glucose to provide energy to living things involved the process of respiration in which oxygen may or may not be used to convert glucose back into CO2. This CO2 goes back into the atmosphere again. The process of combustion also adds to the level of carbon dioxide in the atmosphere. This percentage is said to have increased when human beings started cutting down trees, burning fossil fuels, etc. on a very large scale. Thus, carbon is cycled repeatedly through different forms by the various physical and biological activities and this cycle is therefore called carbon cycle.

Hope you could get an idea from here.
