Answer:

Form a concave meniscus.

Explanation:

Putting water in a drinking glass, it will try to climb up the sides just a little bit, forming a concave meniscus.When pouring the water out, you have to visualize that the water still prefers to adhere to the glass than fall down under gravity, so if it at all can, that is what it will do.

Answer:

Breed "pure" mice with known genotypes that exhibit specific fur and eye colors, and learn how traits are passed on via dominant and recessive genes. Mice can be stored in cages for future breeding, and the statistics of fur and eye color are reported every time a pair of mice breed.

What is meant by transpiration is a necessaru evil?
3241004551 [841]
In plants, transpiration is a process which is inevitable but potentially harmful, because it can cause loss of water. Loss of water can lead to wilting and eventual death of the plant. Even a little stress can interfere with the plant's growth process. 

But, at the same time, transpiration is necessary because of a number of reasons - the transpiration stream aids the processes of mineral absorption, water absorption, energy exchange, helps provide the plant with optimum turgidity, it helps the exchange of gases and so on.

A protein isolated from a thermophilic bacterium shows a molecular weight of 160 kD when eluted from a size-exclusion chromatogr
Amiraneli [1.4K]

Answer:

as a dimer consisting of two identical monomers (80 kDa subunits) that are packed together via hydrophobic interactions

Explanation:

SDS-PAGE (sodium dodecyl sulphate–polyacrylamide gel electrophoresis), is an electrophoretic methodology used to separate proteins that have a molecular weight between 5 to 250 kDa. SDS is a well-known ionic detergent that is able to break hydrophobic interactions and hydrogen bonds. Moreover, size-exclusion chromatography is a filtration technique that separates molecules in solution according to their molecular size. In this case, SDS-PAGE showed that the target protein is composed of two identical subunits (monomers) of 80 kDa each, which were separated by the detergent and formed one single band in the SDS-PAGE gel.

Draw the structure of DNA aand write a short note about it.​
artcher [175]

Answer:

DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The order of these bases is what determines DNA's instructions, or genetic code.

"C. Organisms' characteristics are carried <span> on DNA.</span>" would be the best fit, although this still isn't really the core idea behind natural selection, which is that animals survive based on how "fit" they are for their environment.
