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.

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.

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.

C. All organisms must reproduce the same amount.
O D. The population must be below carrying capacity.

Answers

Answer:

B

Explanation:

There must be genetic variation in the population.

Write down a mechanism for increasing genetic variation in BOTH eukaryotes and prokaryotes.

Answers

Answer:

Genetic variation mechanisms are different in prokaryotes and eukaryotes, Transformation, transduction, and conjugation in prokaryotes whereas crossing over, random assortment, and random fertilization in eukaryotes.

Prokaryotes:

Prokaryotic cells can lead to genetic variation by recombining their genetic material. In prokaryotes, horizontal gene transfer (HGT), in which gene transfer from one organism to another in the same generation. The three most common ways of HGT are transformation, conjugation, and transduction.

Eukaryotes:

Eukaryotic organisms can perform either sexual and asexual or both reproduction in which they are able to transfer genetic material (DNA) to their offsprings. Such transfer of genetic material process is called vertical gene transfer. In sexually reproducing organisms, independent assortment during zygote formation, a mutation in genes, and crossing over during prophase 1 in meiosis is the process that increases the chances of genetic variation.

Natural selection was acting on the population of radish plants. Which of the following DOES NOT satisfy a condition of natural selection as it relates to our radish populations?

a. there was a purple phenotype and a white phenotype
b. the R allele produced a white plant, and rr produced purple plants
c. competition was affecting the reproductive success of at least one of the morphs
d. our populations of radishes were small
e. all of the above are examples of conditions necessary and sufficient for evolution by natural selection

Answers

Answer:

d. our populations of radishes were small

Explanation:

Natural selection is a type of evolution that allows only individuals with favorable characteristics and better adapted to the environment to survive and reproduce offspring with the same favorable characteristics. In this case, to observe a population where natural selection is taking place, population sizes can be disregarded, as this is not a condition for natural selection to take place. However, the other conditions presented in the response options are necessary for natural selection, since it is necessary that there are different phenotypes and genotypes in the population and that competition between them promotes the survival of one group at the expense of the other.
