Step 3: Make a claim. a) Recall what you know about crossing over, independent assortment, and random joining of sex cells durin

g sexual reproduction. b) Now, go back to the claims in Step 2a. Do you support these claims? If so, do you support the totality of the claims or just parts of the claims? c) Based on your prior knowledge, make a claim about the factors that cause inherited genetic variations within populations. Also make a claim about the effects of mutations. Write your claim in your notebook.

Answer:

Crossing over is a process in which exchange of segments occur between two non sister chromatids.

Explanation:

Crossing over is a process in which two non-sister chromatids of homologous chromosomes exchange the segments of genetic material with each other during meiosis. Due to this process, variation occurs in an organism.

Independent assortment is a process in which different alleles are sorted to different gametes which occurs independently and does not effect one another. This process occurs in metaphase of meiosis l.

Joining of sex cells is a process in which sex cells of male and female join together formed a zygote which turn into a new organism. These sex cells are formed during meiosis which are haploid in nature.

Mutation and crossing over are the factors that cause inherited genetic variations within populations.

Sudden change occurs in the genes of an organism due to the exposure of the cell to radiation or chemicals.

Two species of ant compete for limited resources in a front yard until only one species is able to remain. this is an example of
PolarNik [594]
I think this is an example of competitive exclusion principle. Competitive exclusion principle is a proposition that two species competing for the same limiting resource can not coexist at constant population values.For Example the Red squirrel is native to Britain but its population has declined due to competitive exclusion, disease and the disappearance of hazel coppices and mature confer forests i law land Britain.

Which of the following pairs is mismatched? RNA polymerase – makes a molecule of RNA from an RNA template DNA ligase – joins seg
disa [49]

Answer:RNA polymerase – makes a molecule of RNA from an RNA template

Explanation: RNA polymerase is an enzyme that catalyzes the copying of a DNA sequence into an RNA sequence during transcription. RNA polymerase uses a DNA template for the synthesis of an RNA strand. RNA polymerase is also called DNA-dependent RNA polymerase. During transcription, DNA helicase unwinds the double helix of the DNA while the RNA polymerase catalyzes the synthesis of an RNA strand from the DNA.

What is the difference between Archaebacteria, Eubacteria, Protista, and Fungi?
MA_775_DIABLO [31]

Archaebacteria are like Eubacteria, which are just able to survive dangerous conditions, such as high salinity, extreme temperatures, and no oxygen.

Eubacteria are your garden-variety prokaryotic organisms that can cause the common cold and make bread rise, which don't have nuclei.

Fungi are similar to plants in the way that their cells are structured, except they have cell walls made of <em>chitin</em>, instead of cellulose like Plants. They decompose food and eat it using chemosynthesis, breaking it down into organic matter, which allows for the cycling of materials through a food chain.

Protista is really tough. You see, protists are basically a fancy word scientists picked instead of "miscellaneous", because there are plant-like, fungi-like, and animal-like protists. They really have no defining characteristics to speak of except that they have weird quirky qualities that don't allow them to fit in any groups.


Hope this helped! :)
