Describe two ways DNA is different than RNA. Name two roles that hydrogen bonds play in DNA? What is the difference between 10 nm fiber, 30 nm fiber and the DNA loops? Describe histones. What are they made of (ie the types of subunits). How do they interact with DNA?

The discussion for this week will focus on the importance of the two main topics of this chapter (photosynthesis and cellular respiration) to each other. There is a unique balance between these two energy cycles, and your postings should address something specific that addresses this idea. For instance, you can focus on one of the following: the history of these processes (which one we think started first and how that eventually led to the other one), different types of interactions, how other things affect them (poisons, temperatures, global climate, etc.), where the organisms are that perform these processes, which organisms have them, the different parts of each one of these and how they are related or how they came about, or the fact that there are cycles involved and what that may indicate. I need an outside source with this with in paragraph citation as well as a reference citing at the end..

Using what you know about stem cells and cell differentiation, explain HOW bone marrow cells can travel to the brain and differentiate into neurons. Make sure to discuss the role of cell signaling processes and cellular induction.

we learned not only about the importance of Mendel's Laws (segregation and independent assortment) to heredity, but also that there are a number of exceptions to Mendel's Laws. Inheritance follows some basic ideas, but can certainly appear to be a tricky thing if you don't fully understand the basis of how the traits of living things come about. This discussion, therefore, will focus on the exceptions to Mendel's Laws so that it will help you better understand how traits come about. You should look up more information on an exception and provide us with a better understanding of it in your postings. Different examples, importance, effects on traits including diseases, and other things can certainly be addressed. Please let me know if you have any questions on this interesting and relevant topic. I need 2 outside sources with IN-Paragraph citation as well as an ending citation. Use your words.. We also use https://openstax.org/details/concepts-biology

You are a researcher who is interested in three genes in drosophila: The a gene, the b gene and the c gene. You think the genes may be linked, so you decide to do a cross using a true-breeding a+/b+/c+ fly and an a/b/c fly. The F1 generation is all a+/b+/c+. However, when the F1 generation is bred to a true-breeding a/b/c fly, it yields the following offspring phenotypes: 596 a+/b+/c+ ; 589 a/b/c ; 183 a+/b/c ; 176 a/b+/c+ ; 0 a/b+/c ; 0 a+/b/c+ ; 0 a+/b+/c ; 0 a/b/c+. Which What is a possible interpretation of your results?

Group of answer choices

The b and c genes demonstrate 100% (complete) linkage.

The b and c genes are recessive lethal alleles.

The a gene is a dominant lethal allele.

The a and b genes demonstrate 100% (complete) linkage.

Describe why a plant cell would need a large center vacuole compared to an animal cell that only has smaller vacuoles.

What are two types of genetic variation that DO NOT contribute to an immediate response to selection for a population? Think about the constituents of VG when deriving the narrow sense heritability.

4. Indicate what will happen (color change) in the following conditions:

A. Mix McDonald’s Sweet Tea with Benedict’s Solution:__________________.

B. Mix pureed yams with iodine:_____________________________________.

C. Mix a salad dressing of herbs/oil with Sudan Solution:__________________.

D. Mix pureed tofu with Biuret’s Solution:______________________________.

Explain why the structure of myoglobin makes it function well as an oxygen-storage protein whereas the structure of hemoglobin makes it function well as an oxygen-transport protein. Describe briefly the two principal models for the cooperative binding of ligands to proteins with multiple binding sites.
