9. What is the relationship between natural selection and evolution?​

Answers

Answer:

Through this process of natural selection, favorable traits are transmitted through generations. Natural selection can lead to speciation, where one species gives rise to a new and distinctly different species. It is one of the processes that drives evolution and helps to explain the diversity of life on Earth.

Explanation:

Natural selection is a process where organisms that are better adapted to an environment will survive and reproduce. This means that the advantageous alleles of this variant organism are passed on to offspring. Over many generations, the process of natural selection leads to evolution occurring.

Suc- strains cannot utilize sucrose, trp- strains cannot synthesize tryptophan. In the generalized transduction of a suc-trp- strain of E. coli using bacteriophage derived from a suc+trp+ cell, what medium would select for suc+ and trp+?
A) a minimal medium
B) a minimal medium + sucrose
C) a minimal medium + tryptophan
D) a minimal medium + sucrose + tryptophan
E) none of the above

Answers

Answer:

B) a minimal medium + sucrose

Explanation:

Suc+ ⇒ can utilize sucrose, so you have to add sucrose to the medium.

Trp+ ⇒ can synthesize tryptophan, so it is not required to add tryptophan to the medium because the cell can produce it.

According to this, to select for suc+ trp+ you have to only add sucrose to the medium. Thus, it will only grow the cells that can utilize sucrose and can synthesize tryptophan.

Therefore, the correct option is: B) a minimal medium + sucrose

Which effect would you expect a Species Survival Plan to have on the crested
toad population in Puerto Rico?
A. Scientists reintroducing crested toads into the wild
B. Most of the crested toads dying out
C. Invasive species outcompeting crested toads in the wild
D. Most of the crested toad habitat being destroyed
SUBMIT

Answers

The correct answer is A. Scientists reintroducing crested toads into the wild.

Explanation

Species Survival Plan is a conservation program promoted by conservationists and zoologists that specializes in those animals that are near extinct, endangered, or threatened. This program mainly aims to breed these species in captivity to ensure their future preservation and reintroduction to nature. According to the above, the effect that could be expected from the implementation of the Species Survival Plan in Puerto Rico with the crested toads would be the reintroduction of this species into the wild after being bred in captivity.

Which type of RNA functions as the location where proteins are made? mRNA rRNA tRNA siRNA

Answers

Answer: rRNA

Explanation: mRNA is the messenger RNA (sequence determined by DNA) and it exits the nucleus and meets the tRNA (transfer RNA) in the ribosome or more specifically the rRNA (answer). I’m not sure what siRNA is, but I’m 99% sure the answer is rRNA.

The type of RNA that functions as the location where proteins are made would be the rRNA.

rRNAs are known as ribosomal RNAs. They are usually found associated with the ribosome - the organelles responsible for synthesizing proteins in eukaryotic cells.

mRNA is the messenger RNA. They are formed directly from the transcription of DNA in the nucleus and then transported to the cytoplasm. They carry genetic information in coded forms and the codes are translated protein synthesis.

tRNA is the transfer RNA. It carries amino acids and anticodons.

siRNA are small interfering RNA.

In this season the subtropical ridge of high pressure stays over the central Sahara Desert and the low-pressure Intertropical Convergence Zone (ITCZ) stays over the Gulf of Guinea. On its passage over the Sahara, the harmattan picks up fine dust and sand particles (between 0.5 and 10 microns). It is also known as the "doctor wind", because of its invigorating dryness compared with humid tropical air.

4. The inner membrane of the mitochondria is impermeable to ions. How does this fit with what
you've learned about membrane structure? Why is this important to cellular respiration?

Answers

Answer:

The inner mitochondrial membrane contains proteins involved in the electron transport chain. This chain releases energy that is then used to generate an electrochemical gradient, which is subsequently used to synthesize ATP

Explanation:

Mitochondria are membrane-bound organelles that have an inner membrane separated from an outer membrane by the intermembrane space. Moreover, the mitochondrial matrix is located within the inner membrane. The inner mitochondrial membrane contains proteins involved in the electron transport chain and ATP synthesis. Oxidative phosphorylation (electron transport chain) is the third stage of cellular respiration in aerobic organisms in which ATP is generated by transferring electrons from NADH or FADH2 to O2 by a series of electron carriers located in the inner mitochondrial membrane. The trans-membrane complexes of electron carriers are multiprotein enzyme complexes (I–V) and electron carriers (i.e., coenzyme Q10 and cytochrome c) required for the communication between complexes. The electron transport chain is coupled to proton transfer from the matrix out to the intermembrane space, thereby generating a proton gradient which is then used by ATP synthases to synthesize ATP​.

1. Through the activated channels, _________ now flows outwards causing the membrane to repolarize back towards RMP.
2. As the membrane potential ___________, the voltage-regulated sodium channels begin closing which in turn reduces the sodium movement to the ICF
3. With a larger duration of activation than sodium channels, the potassium channels allow for a greater movement of potassium to the ECF causing a short period of_______.
4. With membrane potentials approaching +35 mV, the _________channels become fully activated.
a. Sodium
b. Voltage regulate sodium
c. Potassium
d. Rises towards zero
e. Hyperpolarization
f. Voltage regulated potassium

Answers

Answer:

1. Potassium

2. increasing towards zero

3. hyperpolarization

4. voltage-regulated Potassium

Explanation:

Membrane potential can be defined as the difference in electric charges inside and outside of a cell. The resting membrane potential (RMP) occurs when there is no net current across the membrane and therefore the cell is in a non-excited state. At the RMP, sodium ions (Na+) are more concentrated inside the extracellular fluid (ECF) than inside the intracellular fluid (ICF), while potassium ions (K+)  are more concentrated inside the ICF. The diffusion of K+ outside the cell triggers its hyperpolarization, by becoming the membrane potential more negative compared to the resting potential. As the potential nears +35 mV, the voltage-regulated potassium channels are open, thereby K+ ions leave the cell down its concentration gradient, while voltage-gated Na+ channels become saturated and inactivate.
