Answer:

Starch molecules is too large therefore cannot pass through pores of visking tubing, glucose molecules is small enough to pass through pores of visking tubing. Visking tubing is like small intestine in this experiment, where starch is too large to be absorbed through small intestine into bloodstream, glucose is small enough to diffuse through small intestine and to be reabsorbed into bloodstream.

Answer: In ecosystems, matter and energy are transferred from one form to another. Matter refers to all of the living and nonliving things in that environment. Nutrients and living matter are passed from producers to consumers, then broken down by decomposers. Decomposers break down dead plant and animal matter.

The Panama isthmus is indeed a patch of land which separates its sea from its Atlantic ocean to The pacific in two halves. The Panama Isthmus allows spreading the seafood applicable state, although due to geographical barrier, the very same turtle species were isolated. Its deep squirrels of liquid are diverged quite early as being against shallow water shrimps which are characterized by the rising of the Jamaica isthmus, first off the island can be crossed until it was closed through shallow water prawns and shallow-water animals. If Panama's black sea was established less than 1000 years, it has a greater effect on deepwater shrimp and very low water lobsters. Consequently, in water depth prawns, a disparity in hereditary degree (DNA) is higher than in shallow species. The deep waters have been affected earlier so the variation in DNA sequences throughout all sister species will not be the same.

The best clue that can be used to decide living thing or not a living thing is the observation of living or dead cells present in the specimen. All the living or dead organisms exhibit cells. Cell is a structural and functional unit of life. The growth and metabolism of living organism are dependent upon a cell. A cell in a life form exhibit organelles and components which are not found in non-living objects

The BEST clue you could use to decide: living thing or not a living thing- is option C. is it made of cells and

The living things have some basic characteristic features of life in them that help in determining if an object or thing is living or nonliving thing. these characteristic can be present in all or some, are as follows:

Answer: factors that limit a population size are limiting factors. Biotic potential is the amount of organisms that could be supported in an ecosystem if plenty of resources were available. Factors that cause a population to increase are 1)births: the number of births in a population in a certain period of time. 2) immigration: when organisms move INTO a population.

Explanation:

some examples of limiting factors are natural hazards, amount of food, amount/quality of water and air, predators deforestation.

Note: You will find the chromosomes and the gametes in the attached files

Chromosomes:

Gametes:

Independent assortment occurs when the alleles of two or more different genes distribute in the gametes independently from each other.

Explanation:

Available data:

two pairs of submetacentric chromosomes

IA     -------------------о-----------

IB     -------------------о-----------

IIA    ----------- ------------о------------

IIB    ------------------------о------------

chromosomes Ia and Ib are homologs

IA     -------------------о-----------

IB     -------------------о-----------

chromosomes IIa and IIb are homologs

IIA    -----------------------о------------

IIB    ------------------------о------------

Allele M is located on the long arm of chromosome Ia, and allele m is located at the same position on chromosome Ib

IA     -------M----------о-----------

IB     -------m----------о-----------

Allele P is located on the short arm of chromosome Ia, and allele p is located at the same position on chromosome Ib.

IA     -------M----------о------P---

IB     -------m----------о------p----

Allele R is located on chromosome IIa and allele r is located at the same position on chromosome IIb.

IIA    ------------------------о------R----

IIB    ------------------------о-------r----

Allele G is located on the long arm (q arm) of chromosome Ia, and allele g is located at the same position on chromosome Ib.

IA     -------M---G-----о------P---

IB     -------m----g-----о------p----

Allele N is located on the q arm of chromosome IIa and allele n is located at the same position of chromosome IIb.

IIA    --------N--------------о------R----

IIB    ---------n--------------о-------r----

A). Draw these chromosomes, identifying genes R, r, G, g, N, and n as they might appear in metaphase I of meiosis. Assume there is no crossing over.

IA     ----------G-----о---------

IB     -----------g-----о----------

IIA    --------N--------------о------R----

IIB    ---------n--------------о-------r----

During metaphase I, homologous pairs together migrate to the equatorial plane, where they randomly aline with their kinetochores facing opposite poles. The random arrangement of tetrads is different in every cell going through the meiosis process. There is no equal alinement between two cells. When tetrads aline in the equatorial plane, there is no predetermined order for each of the homologous chromosomes of each tetrad to face one of the poles and then migrate to it while separating. Any chromosome of the homologous pair might face any of the poles and then migrate to it. Each of the chromosomes has two possibilities for orientation at the plane. When the new haploid cells are formed, the number of variations in each cell is also different and depends on the chromosomes that form that cell. This random order in the equatorial plane is what introduces variation into the gametes. It is almost impossible that two gametes resulting from meiosis will get the same genetic charge.

B). Taking independent assortment and the subsequent random separation of chromosomes in anaphase I, draw the chromosomes, with genes identified, present in all possible gametes that could result once this cell completes meiosis. As above, assume there is no crossing over. Explain in your own words what is meant by independent assortment.

Independent assortment occurs when the alleles of two or more different genes distribute in the gametes independently from each other. In other words, a gamete receives an allele from a gene that does not depend on nor influence the allele of another gene in the same gamete. This can only be applied to independent genes. An organism gets only one of the members of the chromatids pair of each parent.

During gamete formation in meiosis, the pairs of homologous chromosomes separate after crossing over, and then chromatids sisters also separate, resulting in the formation of four gametes. Each gamete has different information from the combination of homologous chromosomes belonging to the father and to the mother.

There are four possible combinations, considering that there is no crossing over.

competition plays a very important role in ecology and evolution. The best competitors are the ones who survive and get to pass on their genes.

Answer: Why are normally unseen members of the food web, such as soil microorganisms, essential to the nitrogen cycle? ... Since not all organisms can utilize the nitrogen gas directly, these microorganisms convert nitrogen in different nitrogen compounds, such as ammonia, nitrites, and nitrates. In this article we explore how nitrogen is cycled and the important role of microbes in this cycle. ... Nitrogen is required by all living organisms for the synthesis of organic molecules such as amino acids, nucleic acids and proteins. The Earth's atmosphere contains almost 80% nitrogen gas

Bacteria play a central role:

Nitrogen-fixing bacteria, which convert atmospheric nitrogen to nitrates.

Bacteria of decay, which convert decaying nitrogen waste to ammonia.

Nitrifying bacteria, which convert ammonia to nitrates/nitrites.

Denitrifying bacteria, which convert nitrates to nitrogen gas.

Explanation:

Given that Son 8's mother is a carrier of the blindness allele

Assuming that the father is colorblind due to a genetic mutation, there are a few possible scenarios for how the son inherited the allele for colorblindness.

Genetic inheritance is the study of how certain inherited traits are passed down from generation to generation.

Assuming the father is colorblind due to a genetic mutation, there are a few possibilities for how the son inherited the colorblind allele:

Thus, in any of these scenarios, the son inherited the allele for colorblindness from one or both of his parents.
