<span>The 4 categories of macromolecules include carbohydrates, proteins, lipids, and nucleic acids. Carbohydrates (grains and vegetables) are the largest group at the base of the pyramid, proteins (milk, poultry, eggs, nuts) follow up the pyramid while lipids (fats and oils) are the least amount at the summit of the pyramid. </span>

 

<span>
</span><span>The aim of the pyramid is to recommend ideal  rations for a healthy diet. Carbohydrates provide most of the energy needs for the days’ activities hence taking the largest portion. Proteins are used in building muscles, f0r nutrition, and body’s immunity hence required in lesser amounts compared to carbohydrates. Lipids help the body store energy since they have thrice as much energy as carbohydrates.They also a constituent of cell membranes and also help deliver vitamins. They are required in the least amount to avoid obesity and related illnesses such as cardiovascular <span>diseases</span></span>

How does the photosynthetic reaction center differ from the chorophyll molecules in the antenna complex?
o-na [289]

Answer:

Photosynthetic reaction center differ from the chlorophyll molecules in the antenna complex by the presence  and absence of core pigment and accessory pigment.

Explanation:

Photosynthetic reaction center contain core pigment known as chlorophyll  A which can aborb wavelength of sunlight not more than 700 nm in case of Photosystem 1 and the core chlorophyll pigment of Photosystem 2 absorb light having wavelength of 680nm or less than that.

                           Antenna complex or light harvesting complex  such as chlorophyll b ,Carotenoid,Xanthophyll absorb light energy from sunlight and transfer that light energy to photosynthetic reaction center by resonance energy transfer so that the photosynthetic reaction center uses the same(light energy) in form of chemical energy to out the further reactions of photosynthesis.

In the lab on Trophic Interactions you were looking at behavior of mosquito larvae. The question being asked was: Does prey beha
Korvikt [17]

Answer:

Null hypothesis: the behavior of mosquito larvae doesn't change in the presence/absence of predators added to the tanks in Treatments 2 and 3.

Explanation:

In statistics, the null hypothesis states that there are no differences between the two variables tested in the experiment, while the alternative hypothesis uses the experimental data in order to reject the null hypothesis. In this case, the alternative hypothesis will use the data from treatments 2 and 3 to confirm that predators can modify the behavior of mosquito larvae.

An important technique that helps provide insight into interesting genetic questions at the molecular level, such as reasons for
malfutka [58]

Answer:

DNA sequencing

Explanation:

DNA sequencing is a technique which helps in determining the DNA sequence of any organism. In the human genome project, all the bases that make DNA in humans are sequenced which helped doctors to determine the cause of many genetic diseases and also their treatment.

Hairlessness in dogs can be genetic and the mutated gene can be determined by sequencing the DNA of hairless dog and comparing it with the normal DNA sequence of dog. Therefore the correct answer is DNA sequencing.
