Energy in most ecosystems must flow through autotrophs because only autotrophs can convert solar energy in chemical energy.

Explanation:

This suggests that these are organisms which are entirely based on the Greek name self-producers that can produce complex organic materials by fixing together simple building blocks in their local situation. E.g plants on land. Photosynthesis in plants transforms solar energy into chemical energy using electrons and protons from water. The method of photosynthesis in plants involves a series of steps and reactions that use solar energy, water, and carbon dioxide to produce organic aggregates and oxygen.

A pea plant with round seeds has the genotype rr. if you cross this plant with a wrinkled-seed plant, genotype rr, what is the p

Lapatulllka [165]

I think you wrote this wrong? Is it not round rr vs wrinkled RR?? I'll answer it with that assumption:

You are crossing a rr with an RR:
You only get Rr back so they will phenotypically be all wrinkled

If you are crossing rr with an Rr (so a heterozygote wrinkled):
50% will be Rr (wrinkled)
50% will be rr (round)

Question 9 (Multiple Choice Worth 2 points)

Vilka [71]

The two organisms that are most closely related according to Linnaean taxonomy are <em>Felis catus</em> and <em>Panthera pardalis</em>, because they belong to the same family

<h3>What is taxonomic classification?</h3>

Linnaean system of classification consists of a hierarchy of groupings called taxon. Each taxon is arranged in a hierarchical order.

The hierarchical arrangement of the taxon are as follows:

Kingdom
Phylum/Division
Class
Order
Family
Genus
Species

These taxa are arranged from the most inclusive to the most exclusive i.e. members of the same species are the most closely related in that order.

This suggests that <em>Felis catus</em> and <em>Panthera pardalis</em> are the most closely related because they belong to the same family.

Which of the following is NOT a function of a glycocalyx?

Furkat [3]

Answer:

The incorrect assertive is letter C. it forms pseudopodia for mobility.

Explanation:

The glycocalyx or glycocalyx is a wrapper outside the plasma membrane present in animal cells and some protozoa. The term glycocalix derives from the Greek glykys, sugar, and the Latin calyx, bark, a sugar peel. It consists of lipid-associated carobhydrates, commonly called glycolipids, and protein-associated caroboidates, called glycoproteins.

According of all functions we have about glicocalix, the assertive letter C is the only is not a function about this structure. The other ones, like allows bacteria to stick to a host or the environment, biofilm formation and protection a bacteria about the drying out process are function of the glycocalix.

umka21 [38]

If a test tube has been used, and its contents is supposed to be disposed, carefully pour the contents to the lavatory with a confirmation of a professional (as it may damage the pipelines of the sink) and ensure that there are no splashes created that can contact the human skin. Wash the test tube thoroughly and let dry.
