A population has adopted an evolutionarily stable strategy (ESS) in regards to cooperation or defection. If a new mutant strategy appears that causes an opposite behavior from the norm, which of the following will result?
A. The mutant strategy will not be able to increase in numbers in the population under the influence of natural selection.
B. Antagonistic pleiotropy will allow an equilibrium in which both strategies are maintained in the population.
C. The members of the population using the original strategy will act with aggression toward those exhibiting the mutant strategy.
D. The evolutionarily stable strategy will be displaced because of natural selection in favor of the mutant strategy.
E. Natural selection will maintain the mutant strategy because the variation in strategy may be useful in future environments.
Answer:
A. The mutant strategy will not be able to increase in numbers in the population under the influence of natural selection.
Explanation:
An evolutionarily stable strategy (EES) can be defined as a strategy that is competitively superior to others strategies and cannot be replaced or invaded by any other strategy through natural selection, resulting in punishment for those who deviate from it. Thus, an EES may confer a higher reproductive/adaptive fitness than alternative strategies when it is adopted by most members of the population. Individuals having an ESS are 'spiteful' because they act not only to increase their payoffs but also to decrease the payoffs of their competitors. An EES is resistant to low levels of mutation when all individuals in the population have the same strategy. In game-theoretical terms, an ESS is a strategy such that if all the members of a population adopt this strategy, then no mutant strategies could invade the population under natural selection. In consequence, when all individuals of a population adopt an EES, mutant phenotypes cannot invade and displace the ESS.

How do transitional fossils help explain the evolutionary steps that took place to produce modem organisms?
Answer:
Transitional fossils show how a particular taxa accumulated adaptations to fit particular environments and/or ecological niches
Explanation:
Transitional fossils are fossilized remains of taxonomic groups/species that illustrate an evolutionary transition between a known version of a taxa/species and the current taxa/species. Transitional fossils are fundamental because they can be clearly differentiated from the ancestral group as well as of its derived descendant group. For example, there exist transitional fossils known as "mammal-like reptiles"(i.e., therapsids that gave rise to the true mammals), which are clearly different from current mammals.

Complete each statement by using the appropriate word or phrase from the list. Then place the statements in the order of an action potential repolarization event.
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
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.
why it is important that we have an understanding of geologic time
Answer:
Time is a very important variable in geology because the exact timing of spatially separated events allows us to reconstruct the surface and surface conditions of the ancient earth. Geologic time spans are considerably more difficult to comprehend than historical time spans because they are so incredibly long.
One reason is so that we can fully understand how geological processes that seem impossibly slow can produce anything of consequence. For example, we are familiar with the concept of driving from one major city to another: a journey of several hours at around 100 km/h. Continents move toward each other at rates of a fraction of a millimetre per day, or something in the order of 0.00000001 km/h, and yet, at this impossibly slow rate, they can move thousands of kilometres. Sediments typically accumulate at even slower rates — less than a millimetre per year — but still they are thick enough to be thrust up into monumental mountains and carved into breathtaking canyons.
Another reason is that for our survival on this planet, we need to understand issues like extinction of endangered species and anthropogenic (human-caused) climate change. Some people, who don’t understand geological time, are quick to say that the climate has changed in the past, and that what is happening now is no different. And it certainly has changed in the past. For example, from the Eocene (50 Ma) to the present day, Earth’s climate cooled by about 12°C. That’s a huge change that ranks up there with many of the important climate changes of the distant past, and yet the rate of change over that time was only 0.000024°C/century. Anthropogenic climate change has been 1.1°C over the past 100 years, and that is 45,800 times faster than the rate of natural climate change since the Eocene.

6) In Medieval times a ruler told the peasants that they were free to take anything from the forest that had fallen, branches, trees, leaves etc. But they were not to take any live standing trees. Within a few years the forest was dying. Why
Answer:
Due to lack of nutrients in the soil.
Explanation:
Within a few years the forest was dying because there is no nutrient is present in the soil which can trigger the growth and development of the sol. The fallen parts of trees such as branches, tree and leaves etc are decomposed by decomposers such as bacteria and fungi which turn the fallen materials into nitrogenous materials which can be used by the plant for its growth and development.
Which of the following statements is correct regarding engineering maize plants with a herbicide-resistance gene using Agrobacterium-mediated plant transformation?
a. The Ti-plasmid used for this experiment must contain tumor-inducing genes.
b. The herbicide-resistance gene is cloned into the T-DNA region of the Ti-plasmid.
c. The herbicide-resistance gene is cloned into a region outside of the T-DNA in the Ti-plasmid.
d. A guide RNA is used to transfer T-DNA from Agrobacterium to the plant cell.
e. The whole Ti-plasmid containing the herbicide-resistance gene is inserted into the maize genome after infection with Agrobacterium
Answer:
b. The herbicide-resistance gene is cloned into the T-DNA region of the Ti-plasmid.
Explanation:
Ti-plasmid has the ability to introduce part of its DNA (t-DNA) into the genome of host plants. This is very important for the relationship of genetic manipulation in maize plants, with the aim of inducing a gene that promotes herbicide resistance. In addition, T-DNA has many genes that code for the production of plant growth phytohormones, which is extremely important for the cloning process to work. In this case, we can assume that the correct answer for yours is the letter B.

Explanation:
Osmolarity tells you the concentration of solute particles in solution, osmolarity cannot always tell you the direction of water movement across a membrane.
a. True
b. False
Answer:
a. True
Explanation:
Osmolarity is a measure of solute concentration, that is, it indicates how much solute there is in a liquid. As we know, osmosis is the movement of solute across the cell membrane, where the solute passes from the more concentrated side to the less concentrated side. Osmolarity is directly linked to this concept, but it is not able to indicate the direction of movement of the solute. This is because the solute will only pass through the membrane if it is a penetrating solute. Non-penetrating solutes do not have the ability to move through the membrane, even though the osmolarity of the liquid is high.

Which of the following models describes the way in which DNA Replication occurs?
semiconservative
dispersive
random
conservative
Answer:
semiconservative
Explanation:
The semiconservative model of DNA replication states that only one DNA strand is used as template for the synthesis of the other new strands. In DNA replication, the DNA molecule is first unwind into a replication fork containing two single strands of DNA.
After unwinding, DNA polymerase synthesizes new complementary strands of DNA using each of the old strands. So in essence, the two DNA molecules after replication consists of one old and one new strand of DNA. This is basically the semi-conservative model of DNA replication.
A red blood cell has an intracellular concentration of 300 mOsM of nonpenetrating solute. What best describes a solution containing 100 mM NaCl and 150 mM urea relative to the red cell?
The solution is hypertonic to a solution containing 100 mM NaCl and 150 mM urea relative to red blood cell.
The term "hypertonic" refers to a solution that has a higher concentration of solutes compared to another solution. In this case, the solution containing 100 mM NaCl and 150 mM urea has a higher concentration of solutes than the intracellular concentration of the red blood cell, which is 300 mOsM of nonpenetrating solute.
The concept of tonicity is important in understanding how solutions affect cells. When a solution is hypertonic to a cell, it means that there is a greater osmotic pressure outside the cell than inside. In this specific scenario, the hypertonic solution has a higher concentration of solutes (NaCl and urea) than the red blood cell's internal nonpenetrating solute concentration.
As a result, water molecules will tend to move from an area of lower solute concentration (inside the cell) to an area of higher solute concentration (outside the cell) in an attempt to equalize the concentration on both sides of the cell membrane. This movement of water out of the cell can lead to cell shrinkage or crenation, which occurs when the cell's volume decreases due to water loss.
In summary, the solution containing 100 mM NaCl and 150 mM urea is hypertonic to the red blood cell because it has a higher concentration of solutes than the cell's internal nonpenetrating solute concentration, leading to water movement out of the cell and potential cell shrinkage.

Name three different cells in a leaf that contain chloroplast. Please help
The LEAF as a photosynthetic organ includes the following cells which contains CHLOROPLASTS
• the palisade mesophyll
• the spongy mesophyll and
• the stomatal guard cells
The LEAFS are the main organ of photosynthesis. Photosynthesis is the process by which green plants manufacture their food in the presence of sunlight. This takes place in the CHLOROPLASTS of these plant. CHLOROPLASTS are structures that contains chlorophyll which traps in energy from the sunlight.
The mesophyll tissues are located between the upper and the lower epidermis of the leaf. The palisade mesophyll, which is found at the upper part, contains numerous CHLOROPLASTS and is the main site of photosynthesis in the leaf.
The spongy mesophyll is located at the lower part of the epidermis. They are irregularly arranged with air spaces between them which are linked to the stomatal openings. They also contain CHLOROPLASTS.
The stomatal guard cells are a pair of bean-shaped cells which controls the opening and closing of stomata. These cells contains CHLOROPLASTS which contributes to the movement of stomata.
Therefore the three different cells of the leaf that contains CHLOROPLASTS are the palisade mesophyll, the spongy mesophyll and the stomatal guard cells.

Explanation:
The stratum corneum consists of the top layer of the epidermis (i.e., skin). Nails represent a modification of the epidermis and they are composed of densely packed dead skin cells (keratinocytes), which are rich in a protective protein called alpha-keratin. The nail plate is the hard keratinized part of the nail. The nail bed is the skin underneath the nail plate. The nails grow from the proximal portion of the nail bed, which is known as the nail matrix. The main function of the nails is to protect the tips of fingers and toes from injury.
