Which lipid has the greatest influence on blood cholesterol levels?

List four methods that can be used to separate mixturea and give an example of each method

Evgesh-ka [11]

Distillation, Filtration, evaporation, and Chromatography

The filtration process is generally used to separate a suspension mixture where small solid particles are suspended in liquid or air.

Distillation uses boiling to separate mixtures of liquid solutions. It takes into account that different substances in the mixture will have different boiling points..

Chromatography is the separation of a mixture by passing it in solution or suspension or as a vapor (as in gas chromatography) through a medium in which the components move at different rates

Evaporation is a technique used to separate out homogenous mixtures where there is one or more dissolved solids. This method drives off the liquid components from the solid components

What is one way water moves through the nonliving parts of an ecosystem

Crank

Evaporation. Transpiration and photosynthesis deal with plants, living things. Sweating with humans, living things. Evaporation does not, therefore leaving it the only option left.

Which pattern describes the levels of biodiversity across the fossil record?

Leto [7]

Biodiversity generally refers to the variety and variability of life on Earth. According to the United Nations Environment Programme(UNEP), biodiversity typically measures variation at the genetic, species, and ecosystem level.[1] Terrestrial biodiversity tends to be greater near the equator,[2] which seems to be the result of the warm climateand high primary productivity.[3] Biodiversity is not distributed evenly on Earth, and is richest in the tropics. These tropical forest ecosystems cover less than 10 percent of earth's surface, and contain about 90 percent of the world's species.[4] Marine biodiversitytends to be highest along coasts in the Western Pacific, where sea surface temperature is highest, and in the mid-latitudinal band in all oceans. There are latitudinal gradients in species diversity.[5]Biodiversity generally tends to cluster in hotspots,[6] and has been increasing through time,[7][8] but will be likely to slow in the future.[9]

Rapid environmental changes typically cause mass extinctions.[10][11][12] More than 99.9 percent of all species that ever lived on Earth, amounting to over five billion species,[13] are estimated to be extinct.lstimates on the number of Earth's current species range from 10 million to 14 million,[f which about 1.2 million have been documented and over 86 percent have not yet been described] More recently, in May 2016, scientists reported that 1 trillion species are estimated to be on Earth currently with only one-thousandth of one percent described.[18]The total amount of related DNA base pairson Earth is estimated at 5.0 x 1037 and weighs 50 billion tonnes.[19] In comparison, the total mass of the biosphere has been estimated to be as much as 4 TtC (trillion tons of carbon).[20] In July 2016, scientists reported identifying a set of 355 genes from the Last Universal Common Ancestor (LUCA) of all organisms living on Earth.[21]

The age of the Earth is about 4.54 billion years.[22][23][24] The earliest undisputed evidence of life on Earth dates at least from 3.5 billion years ago,[25][26][27] during the Eoarchean Era after a geological crust started to solidify following the earlier molten HadeanEon. There are microbial mat fossils found in 3.48 billion-year-old sandstone discovered in Western Australia.[28][29][30] Other early physical evidence of a biogenic substance is graphite in 3.7 billion-year-old meta-sedimentary rocks discovered in Western Greenland.More recently, in 2015, "remains of biotic life" were found in 4.1 billion-year-old rocks in Western Australia.[32][33] According to one of the researchers, "If life arose relatively quickly on Earth .. then it could be common in the universe.

What is the probability that each of the following pairs of parents will produce the given offspring: 1. AABbCc x aabbcc à AaBbC

ICE Princess25 [194]

Answer:

1) AaBbCc, 50% - 2) AAbbCC, 3,125% - 3) AaBbCc is 12,5%.

Explanation:

1º cross.

Parental) AABbCC x aabbcc

Gametes) ABC AbC ABC AbC ABC AbC ABC AbC

abc abc abc abc abc abc abc abc

Punnet Square) Only filled with the progeny genotype AaBbCc.

ABC AbC ABC AbC ABC AbC ABC AbC

abc AaBbCc --- AaBbCc --- AaBbCc --- AaBbCc ---

F1 Genotype) 32/64 AaBbCc

32/64 AabbCc (shown as the symbol "---" in the

punnet square)

The probability of producing offspring with genotype AaBbCc is 50%.

---------------------------------------------------------------------

2º cross.

Parental) AABbCc x AaBbCc

Gametes) ABC ABc AbC Abc ABC ABc AbC Abc

F1 Genotype) 2/64 AAbbCC

The rest of the progeny have different genotypes that are represented with the symbol "---" in the punnet square.

The probability of producing offspring with genotype AAbbCC is 3,125%.
