Fill in the blank below with the vocabulary word that best completes the sentence. ___is the science of naming and classifying o

ivanzaharov [21]

Taxonomy is the science of naming and classifying organisms based on structural comparisons and genetic evidence.

Taxonomy is the science of finding, describing, classifying and naming biological organisms (plants, animals and microorganisms) based on shared characteristics and genetic evidence. Organisms are arranged into taxonomic ranks, and groups of a certain rank can be combined to form a higher rank, thereby forming taxonomic hierarchy. The main ranks that are used in taxonomy currently are domain, kingdom, phylum, class, order, family, genus and species.

What would happen to the concentrations of ATP, NADPH and Sugars if PSII stopped working?

dezoksy [38]

Answer:

1. ATP - decrease

2.NADPH - decrease

3. sugars - decrease

And True- Both ATP and NADPH are needed to make sugars.

Explanation:

Photosynthesis is a form of biosynthesis that produces glucose from the reactants; it uses energy from sunlight, along with carbon dioxide and water. It happens in the chloroplast in two phases; the light-dependent and dark reactions. In the light reaction, solar energy stimulates photosystems, formed from pigments like chlorophylls.

Chlorophyll forms photosystems of proteins known as complex proteins (PS I & PSII). PS II absorbs and moves the reaction center with light energy.

H+, and oxygen, are formed from a water molecule as it's broken apart.
From photosystem II, electrons are transferred to photosystem I.
ATP is synthesized from ADP along with inorganic phosphate.
To form NADPHH, H+ is added to NADP

If PS II no longer works, there will be less ATP, NADPH, (both used later on) and no sugars produced.

In the dark reaction, products of the light reaction are used to make sugars. Here, in the Calvin cycle, the enzyme, RuBisCO, catalyzes the fixation of CO2 with Ribulose 1,5-bisphosphate (RuBP).

What is paninis genotype for the agouti fur gene?

EastWind [94]

Answer:

The Agouti gene controls the distribution of black pigment. The dominant allele A restricts black pigment to the points of the horse (mane, tail, lower legs and ear rims), as seen, for example, in bays and buckskins.
