Directions: Select each correct answer. More than one answer may be correct.Rodrigo is using the design process to make a device that will cool a drink without ice or electricity. His first prototype was simply an airtight, watertight pouch containing 40 g of ammonium chloride (NH4Cl). He added 100 mL of water to the ammonium chloride, sealed the pouch tightly, and then wrapped the pouch around a small bottle of water. He tested his prototype by measuring the temperature of the bottle of water over time. Next, Rodrigo performed the same test with different amounts and different concentrations of the ammonium chloride solution. For each set of measurements, he found the lowest temperature reached by the bottle of water and calculated the total temperature change. The table below summarizes his results. Maximum Cooling Achieved ___________________________________________ trial 1 2 3 4 5 6 7 ___________________________________________ grams of NH4Cl 30 40 50 50 60 70 80 ___________________________________________ amount (mL) of water added 100 100 100 150 150 200 200 ___________________________________________ greatest temperature change (–°C) 3.6 4.3 4.3 4.8 5.2 5.6 5.8 ___________________________________________ Finally, Rodrigo held the amount and concentration of the solution constant while trying different amounts of insulation.

Evolution is change in a population over time and includes the gene pools of that population. How does biogeographic isolation allow for the change of gene pools over time? A) biogeographic isolation affects the random changes that take place within gene pools
B) biogeographic isolation affects the changes in gene pools that result from which organisms are breeding
C) biogeographic isolation determines who will win competition for mates
D) biogeographic isolation determines the time that populations will breed

Answers

Correct answer: A) bio-geographic isolation affects the random changes that take place within gene pools

The bio-geographic isolation of the species takes place when the geographical barrier work as a distinguishing agent. It takes place when the group of animals, plants and other creatures are not allowed to mate with each other.

The mixing of there genes within the same species is separated by the geographical barrier.

The barrier allows the mating of the species in a different way as compared to the previous one.

Biogeographic isolation allows for the change of gene pools over time as (A) biogeographic isolation affects random changes that take place within the gene pool.

Further Explanation:

Evolution is defined as the process of change in the heritable characteristics. This process takes over in time duration of a few generations. The heritable characteristics are the expressions of genes that are passed on from parents to offspring. Evolution may occur through various processes such as genetic drift, natural selection.

Genetic drift is defined as the variation of the relative frequency of varieties of genotype. There is a chance of disappearance of a particular trait from the population.

Natural selection is defined as a process that results in the adaptation of an organism to its environment in which the individual can reproduce and survive.

Gene pool refers to the collection of all available genes that are available to pass down from parents to offspring in the population of single species. The gene pool determines which phenotypes are present in the population at a given period.

Isolation refers to the process in which organisms of the same species are separated as a result of environmental change. This process occurs so that variation can be brought. When organisms become isolated the two groups are not able to reproduce together so, variations and mutations that are confined only to a group.

The following are the five types of isolation;

• Temporal isolation

• Behavioral isolation

• Ecological isolation

• Geographical isolation

• Mechanical or Chemical isolation

Biogeographic isolation refers to the separation of members of different species through geographical or biological barriers. This isolates the reproductive patterns of the members of the same population and results in the new way of mating in the isolated species. The species that are isolated genetically due to mutations and variations. These isolated groups evolved and lead to the formation of new species.

Which of these best demonstrates mutualism between certain types of bacteria and humans

Answers

Mutualisam between types of Bateria and Humans

Bacteria and the human both get benefit from each other and this relation is mutualism. Bacteria stay inside nose, mouth, intestines, and many more areas of the body surface. They help human by giving response to pathogenic bacteria for protection of immune system.

They metabolize nutrients, vitamin production and wastes process in human’s digestive system. On the other hand, human provides them place to live. These above best demonstrates mutualism between bateria and humans.    

I cannot find the propositions if it is a MCQ, so I will tell what a bacterial mutualism is:

Mutualism is an exchange between species (two or more) in which the mixed organisms profit from this exchange. Unlike commensalism, the associated species adapt, because the modification of one can affect the survival and reproduction of the affiliated species.

Many mutualistic bacteria live and develop in us, for example, the intestinal flora synthesizes vitamin K, a vitamin that is necessary for the absorption of our food. This same intestinal flora also hinders the proliferation of pathogenic bacteria as well as that of commensal bacteria potentially dangerous.

The discovery that traits have dominant and recessive varieties of is contributed toA.) Charles Darwin.
B.) Francis Crick.
C.) Gregor Mendel.
D.) Rosiland Franklin.
I'm almost 100% sure it's C

Answers

The correct answer is option C

Gregor Mendel was the one who discovered that the traits have two forms, one is dominant and other one is recessive.

While performing the experiments with the pea plants he came to know about the traits. Every trait has two forms.

The dominant form of trait is visible in the First generation (F1) and the recessive trait is visible in the second generation (F2).

Example: Shape of seed : round (dominant) and wrinkled (recessive)
Well, you're correct! :) The answer is Gregor Mendel. :)

Electrons are excited in photosystem I. What do these electrons combine with in order to produce an energy-carrying molecule?

Answers

Below are the choices that can be found elsewhere:

a. ADP 

b. ATP 

c. glucose 

d. NADP+

The answer is d. NADP+ 
The electrons combine with NADP+ molecules to form NADPH molecules. The NADPH molecules then travel to the stroma of the chloroplast to carry out the Calvin cycle. The Calvin cycle then produces glucose, which is the energy carrying molecule. The glucose molecule is used in cellular respiration to make ATP, so the cell can harness the energy from the glucose molecule.

The answer to this problem is in a Nadpt+
