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
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.

High altitude adaptation is a complex physiological process that involves an increase in both the number of Hb molecules per erythrocyte and the total number of erythrocytes. It normally requires several weeks to complete. However, even after one day at high altitude, there is a significant degree of adaptation. This effect results from a rapid increase in the erythrocyte BPG concentration.
a. Try to do this without looking at the graphs. If oxygen-binding curves for both high altitude adapted hemoglobin and normal, unadapted Hb were plotted together, would the curve for high altitude adapted Hb be to the left of, to the right of or the same as the curve for unadapted Hb? Explain.
b. Is the oxygen binding affinity of high-altitude adapted Hb higher, lower, or the same as that of unadapted Hb? Explain.
Answer:
a. To the right
b. higher
Explanation:
From the information given:
a.
The oxygen-adsorption curve of the elevated high altitude modified the hemoglobin and this will move to the right because there is a reduced amount of oxygen available at high altitude, as well as an increase in carbon dioxide and H+ ion concentration, temperature, and all of which raise pH and shifts the curve towards the right.
b.
As there is a low relative partial pressure of oxygen at high altitude, the oxygen-binding attraction of high altitude adaptable hemoglobin is greater and higher than that of unadapted hemoglobin under pulmonary oxygen loading. This is important to optimize the oxygen concentration levels in blood circulation and blood tissues.
How and why does the epidermis produce new skin cells?
Answer:
About 95 percent of the skin cells in the epidermis are devoted to creating new skin cells in the lower two levels of the epidermis, which then cycle to the top layer to help form the stratum corneum. Eventually the dead cells of the stratum corneum flake off as new keratinocytes move up, and the cycle repeats itself.

B. Mitochondria was once a eukaryotic
organism.
C. Mitochondria was once a primkaryotic
organism.
Answer:
A
Explanation:
its a
The most likely explanation here is that mitochondria was once a prokaryotic organism. The correct option is A.
What is mitochondria?Mitochondria are membrane-bound cell organelles that produce the majority of the chemical energy required to power the cell's biochemical reactions (mitochondrion, singular).
The mitochondrial energy is stored in a small molecule known as adenosine triphosphate (ATP).
Mitochondria are special compartments (organelles) in our cells best known for their role as powerhouses, converting food molecules into ATP, a molecular fuel for the rest of the cell.
Mitochondria and chloroplasts most likely evolved from engulfed prokaryotes that were once self-contained organisms.
At certain point, an aerobic prokaryote was engulfed by a eukaryotic cell, which then formed an endosymbiotic relationship with the host eukaryote, eventually developing into a mitochondrion.
Thus, the correct option is A.

Give the common name of a eukaryotic microbe that is unicellular, walled, nonphotosynthetic, nonmotile, and bud-forming.
Answer:
Yeast
Explanation:
The correct answer would be yeast.
Yeast belongs to the fungi kingdom. Organisms in the fungi kingdom are generally eukaryotic in that their cells contain a nucleus and membrane-bound organelles such as mitochondrion. Fungal cells lack chlorophyll and are therefore nonphotosynthetic. They are also nonmotile
While fungi exhibit different body forms in terms of body complexity, the only unicellular form is yeast. The organism possesses all the attributes of fungi highlighted above, has a cell wall made largely of chitin, and reproduces through budding.
Answer: Yeast.
Explanation:
Yeasts are eukaryotic organisms, more precisely microscopic fungi that do not form filamentous networks (hyphae), classified as ascomycetes or basidiomycetes and are predominantly unicellular in their life cycle. The cell wall of yeasts is composed of complex "B"-glucan polysaccharides, mannoproteins and chitin. Also, yeast are non-motile organisms when they grownon a solid media.
They usually reproduce asexually by budding or bipartition and by having sexual stages that are not attached to a sporocarp (fruiting body). During asexual reproduction, a new bud emerges from the mother yeast when suitable conditions are met, after which the bud separates from the mother upon reaching adult size. In the case that they reproduce sexually, this occurs by means of ascospores or basidiospores. In conditions of nutrient scarcity, yeasts that are able to reproduce sexually will form ascospores.
Yeasts are important because of their ability to carry out the decomposition by fermentation (predominantly alcoholic) of various organic compounds, mainly sugars or carbohydrates, producing different substances. Therefore, they do not photosynthesize to obtain energy, since they do not possess chlorophyll (pigment responsible for capturing solar energy for photosynthesis).

What is meant by Vetebral Column?
At her initial evaluation, Ms. Jones reports that she has lost 25 pounds over the past eight months despite an increase in her appetite. She complains of extreme fatigue, heart palpitations and irritability. Clinical observations reveal a protrusion of the eyeballs and hand tremors. You suspect that she might have:
a. hypothyroidism
b. diabetes mellitus
c. hypopituitarism
d. hyperthyroidism
Answer:
d. hyperthyroidism
Explanation:
Hyperthyroidism is a condition that occurs when the thyroid gland in our body secretes too much of the thyroxin hormone. Thyroid gland is a butterfly shaped gland that is located in our neck and it produces the hormone called thyroxin. Excess production of thyroxin leads to a condition named hyperthyroidism.
A person's metabolism increases when he or she is suffering from hyperthyroidism. One's weight is lost but the appetite increases. Other symptoms are extreme fatigue, irritability, heart palpitations, sweating and puffy eyes.
Thus in the context, Ms. Jones is suspect to have hyperthyroidism as she she is showing all the above symptoms.
Comb jellies are:____.
A. Bilaterally symmetrical.
B. Similar to a cnidarian polyp.
C. Distinguished by eight bands of cilia.
D. Colonial animals.
E. Carnivores that use nematocysts to capture prey.
Answer:
C. Distinguished by eight bands of cilia.
Explanation:
Ctenophora, also known as comb jellies, represents a phylum of transparent, mostly pelagic, invertebrate marine animals that live around the world. This group characterized by eight rows of cilia (singular cilium) that are used for locomotion. Cilia are organelles and/or structures that extend from the surface of eukaryotic cells, which can be used to move the surrounding fluid, resulting in cell movement. This phylum is divided into two classes: Tentaculata (with tentacles) and Nuda (without tentacles).

Coffee trees grown in the shade of taller forest trees produce fewer coffee beans than trees grown on cleared forestland. However, unlike coffee grown in full sun, shade-grown coffee preserves some habitat for forest birds and other organisms. What is one advantage of growing coffee in the shade?
A. It harms the environment.
B. It provides farmers with greater profits.
C. It costs more than other growing methods.
D. It helps maintain forest biodiversity.
Answer:
d
Explanation:
provides animals with homes letting them breed
It helps maintain forest biodiversity. Therefore, option (D) is correct.
One advantage of growing coffee in the shade is that it helps maintain forest biodiversity. By growing coffee trees in the shade of taller forest trees, farmers preserve some habitat for forest birds and other organisms, which can help to maintain the overall biodiversity of the forest ecosystem.
This is particularly important in regions where forests are being cleared for agricultural purposes, as it can help to mitigate the negative impact on the environment.
While shade-grown coffee may produce fewer coffee beans than trees grown on cleared forestland or in full sun, it provides important ecological benefits that are not captured by purely economic considerations
