The cell membrane plays an role in the transport of substances into and out of cells. Which is an example of passive transport?

Answers

Answer 1
An example of passive transport is diffusion, the movement of molecules from an area of high concentration to an area of low concentration. Carrier proteins and channel proteins are involved in facilitated diffusion.

Explain the basis for the great diversity of proteins in living organism.

Answers

Answer:

Explanation:

Protein functions are so diverse because of the many unique three-dimensional structures protein polymers form. Despite such variety, proteins also share several specific structural characteristics in their monomers, the amino acids. Structural similarities among amino acids make protein synthesis a uniform and regulated process; however, each amino acid contains a unique structural component as well. Specific differences between each amino acid interact to create unique three-dimensional protein structures. Combined, the similarities and differences between amino acids explain how cells can build a diverse pool of proteins from the same set of building blocks. Protein synthesis involves building a polymer of amino acids with complex three-dimensional structure. Dehydration synthesis forms a peptide bond between amino acids and releases a water molecule.

What features of integrated pest management make it a good approach to preserving ecosystems?

Answers

Answer:

Allowing a small but controlled portion of a pest population to remain does less damage to ecosystems, soils, water, and air. Another feature of IPM would be making a habitat more complex, such as mazes, so it can slow the spread of parasites. No-till or low-till agriculture is another feature of IPM because this helps natural enemies of some pests to build up in the soil, whereas plowing destroys the habitats of these enemies.

Two heterozygous parents have ___________chance of contributing one of their alleles to each offspring​

Answers

Answer:

Two heterozygous parents have a 50% chance of contributing one of their alleles to each offspring.

Explanation:

Individuals who are heterozygous for a specific trait have two different alleles in the gene that determines that trait. This characteristic makes their chances of contributing each of their alleles to the offspring 50%.

The alleles of a gene are distributed in the gametes by the process of meiosis, which results in daughter cells with half the genetic charge, so each gamete can only have one copy of the allelic pair of a gene.  

On the other hand, if an individual has two equal alleles for a characteristic in a gene, he has a 100% chance of passing that allele on to his descendants.

1. Which genotype(s) and phenotype for fur length are dominant?

2. Which genotype(s) and phenotype for fur length are recessive?

Answers

Complete question:

You will find the complete problem in the attached files, where all the proposed crosses are detailed.

Answer:

1. Which genotype(s) and phenotype for fur length are dominant?  

Genotype: FF + FfPhenotype: Short fur

2. Which genotype(s) and phenotype for fur length are recessive?

Genotype: ffPhenotype: Long fur

Explanation:

Available data:

F is the dominant allele that codifies for short furf is the recessive allele that codifies for long fur

CROSSES:

1) Test One: If I breed a short fur, FF female with a short fur, Ff male, then I will expect to see what type of offspring?  

all short fur;  some short and some long fur;  all long fur offspring.

Cross:        FF   x   Ff

Gametes) F   F     F   f

Punnet square)   F         F

                  F     FF       FF

                  f      Ff        Ff

F1) Genotype:

     2/4 = 1/2 = 50% FF

     2/4 = 1/2 = 50% Ff

     Phenotype:

    4/4 = 100% Short-fured individuals

2) Test Two: If I breed a short fur, Ff female with a short fur, Ff male, then I will expect to see what type of offspring? Pick 1)

all short fur;  some short and some long fur;  all long fur offspring.

Cross:         Ff   x   Ff

Gametes) F   f      F   f

Punnet square)   F         f

                  F     FF       Ff

                  f      Ff        ff

F1) Genotype:

     1/4 = 25% FF

     2/4 = 1/2 = 50% Ff

     1/4 = 25% ff

     Phenotype:

    3/4 = 75% Short-fured individuals

    1/4 = 25% long-fured individuals

3) Test Three: If I breed a long fur, ff female with a long fur, ff male, then I will expect to see what type of offspring? Pick 1)

all short fur;  some short and some long fur;  all long fur offspring.

Cross:        ff   x   ff

Gametes) f   f     f   f

Punnet square)   f         f

                      f     ff       ff

                      f      ff       ff

F1) Genotype:

     4/4 = 100% ff

     Phenotype:

    4/4 = 100% long-fured individuals

Renewable energy is energy from sources that
a.are not used up faster than they are formed.
b.humans can manufacture.
c.will take years to deplete.
d.were once living organisms

Answers

Correct answer - B Humans can manufacture.

Why? - A renewable energy source means energy that is sustainable - something that can't run out, or is endless, like the sun. ... It means sources of energy that are alternative to the most commonly used non-sustainable sources - like coal. HUMANS can be considered renewable energy sources and batteries at the same time. Unlike fossil fuels, human power can be a clean energy source, which produces little or no air pollution and soil contamination.

Bear in mind the biological definition of a species and also the appearance and distribution of the named populations of Ensatina. Which populations could be considered a species separate from E. e. eschscholtzii?

Answers

Answer:

E.e. oregonesis

E.e. platensis

E.e. xanthoptica

E.e. croceater

E.e. eschscholtzii

E.e. klaubori

Explanation:

The species mentioned above are probably separate species from E.e. eschscholtzii, which arose through ring speciation that occurs when a species is geographically distributed in a circular pattern. After this distribution, geographic isolation occurs, causing individuals in each different region to evolve differently, becoming other species, even reaching the point where it is not possible to cross them.

Fifty years ago, bed bugs were nearly eliminated in the United States by using of pesticides like DDT. Today bed bugs are back in beds and theaters. DDT is no longer used due to environmental issues. Pyrethrums are currently the top choice for bed bug infestations. Pyrethrums are especially useful to us because they generally have a stronger effect on bugs than on humans and animals.

Some bed bugs had mutations in their genetic code which allowed them to survive the chemical pesticide and they produced chemically resistant offspring. How can this be explained?
