Answer:
a tropical location as an area near the equator a temperate location is any area that that lies between the tropical and polar zones and a tundra is the coldest of all the biomes. Tundra comes from the Finnish word tunturi, meaning treeless plain. It is noted for its frost-molded landscapes, extremely low temperatures, little precipitation, poor nutrients, and short growing seasons.

66. A 64-year-old woman, who has always been proud of her suntanned, healthy look, is referred to a dermatologist with a blue-violet, painless, 1.5-cm lump in the skin of her left shoulder. The lump is firm and cannot be moved, and has grown very rapidly over the past few weeks. The mass is removed surgically and the pathologist diagnoses it as a Merkel cell carcinoma. If the UV radiation to which her skin was exposed affected the Merkel cells, what other cell type sharing the same specific epidermal layer might also be affected
Answer:
Basal stem cells for keratinocytes
Explanation:
Keratinocytes are epidermal cells located in the outermost layer of the skin (i.e., the epidermis). Moreover, the cells located in the basal layer of the skin are known as basal keratinocytes or basal cells. These basal cells are proliferative cells that undergo differentiation in order to form suprabasal epidermal layers. Merkel cells are neuroendocrine cells that are located in the basal layer of the skin (scattered among basal keratinocytes), which are attached to surrounding keratinocytes by intercellular junctions called desmosomes.

Explain the evolution of altruism.
Answer:
Altruistic behavior, such as sterile worker ants caring for the offspring of their queen, evolves only between related individuals through what is known as kin selection — or so many evolutionary biologists have thought since the 1960s.
Describe how pollution can cause acid rain, and how acid rain affects the ecosystems of surrounding areas?
Pollution specifically air pollution can cause acid. Gases such as sulphur (IV) oxide and Nitrogen (IV) oxide when they are released into the atmosphere and comes into contact with precipitation, that is rain water causes acid rain. Sulphurous acid and Nitric acid is formed thus the rain falls in acidic form.
Acid rain when it falls on the leaves of the flora (plants) causes removal of the green colouring matter (chlorophyll) thus making plants to be deficient of food. Food in plants is made my the process of photosynthesis, removal of chlorophyll in plants kills them due to lack of food.
Also when acid rain finds it's way into the water bodies through surface runoff, aquatic animals such as fishes die due to lack of favourable environment and oxygen deficiency in water. Acidity in the soil also kills important decomposers therefore soil aeration is altered.
Genetic drift in a population affects the gene pool in which of the following ways?
decrease in genetic variation
increase in genetic variation
increased in mutations
decreased in gene flow
Answer:
Sometimes, there can be random fluctuations in the numbers of alleles in a population. These changes in relative allele frequency, called genetic drift, can either increase or decrease by chance over time. ... Genetic drift can result in the loss of rare alleles, and can decrease the size of the gene pool.
Genetic drift in a population affects the gene pool by decreasing genetic variation.
What is genetic drift?Genetic drift is a mechanism of evolution that occurs due to random fluctuations in the frequency of alleles (alternative forms of a gene) in a population. It refers to the random changes in the frequency of alleles that occur by chance alone, rather than through natural selection or other selective pressures.
Genetic drift is more likely to occur in smaller populations, where chance events can have a greater impact on the frequency of alleles. The effects of genetic drift can result in the loss of certain alleles from a population over time, or the fixation of one allele in a population, meaning that it becomes the only allele present at that particular gene locus.
Two forms of genetic drift are bottleneck effect and founder effect. In the bottleneck effect, a sudden reduction in population size can cause the loss of genetic diversity, while in the founder effect, a small group of individuals colonizes a new area, leading to the establishment of a new population with a limited subset of the genetic diversity present in the original population.

Match each organelle with the main life function(s) it helps the cell perform. Each basic function of life can be used more
than once, and many organelles will have more than one possible answer. Choose one answer only,
Organelle list - nucleus, mitochondria, golgi apparatus, endoplasmic reticulum, ribosomes, lysosomes, vacuoles, cell membrane, chloroplast, cell wall
The answer could either be 1. reproduction 2. interaction with the environment 3. growth 4. uses energy 5. waste production (each function can be used more than once)
Answer:
The correct answer is -
nucleus - reproduction, mitochondria- reproduction, golgi apparatus - waste production, endoplasmic reticulum - growth, ribosomes - growth, lysosomes- waste production, vacuoles - growth, cell membrane - interaction with the environment, chloroplast - uses energy, cell wall - interaction with the environment
Explanation:
A Cell has various organelles with more than one generic function such as the nucleus not just play role in cell reproduction but also plays role in regulating other organelle and cell growth by transcription. Mitochondria produces and provides energy for many functions such as growth, reproduction and substance transport.
Golgi apparatus package proteins and wastes to transfer them out of the cell. The ndoplasmic reticulum modifies the protein produced by ribosomes and helps in growth of the cell. Lysosomes digest waste and cell debris by lysosomal vesicles. Cell membrane and cell wall interact with outer environement.
The total number of molecules of ATP produced during glycolysis is ______, which results in a net production of _____ ATP.
Answer:
The answer is "4 and 2 ".
Explanation:
The overall glycolysis ATP number is 4 of one hydroxyl group. In the first part of the glycolysis 2 ATP molecules are used, so that 2 ATP molecules are net gained. 2. In addition, 2 NADH atoms in the glycol are also created. This is why the total ATP molecules produced during metabolism are 4, resulting in a net output of 2 ATP.
The DNA of a prokaryote is arranged in a single coiled chromosome located in a region called the ____________ . Some prokaryotes carry genes on extrachromosomal pieces of circular DNA called ____________ .
Answer:
1. Nucleoid
2. Plasmid
Explanation:
Prokaryotes are groups of organisms characterized by the lack of a membrane-bound nucleus in their cell. Due to this, the genetic material (DNA) of prokaryotes are found naked i.e. not housed. The DNA of a prokaryote is arranged in a single coiled chromosome located in a region of the cell called NUCLEOID.
However, some prokaryotes e.g. bacteria carry genes on extrachromosomal pieces of circular DNA called PLASMID. Plasmids carry certain genes like antibiotic resistance genes.

Why does the thermosphere increase in temperature as altitude increases?
Answer:
The thermosphere is the outer layer of the Earth's atmosphere, extending from about 53 miles to more than 370 miles above the surface. The temperature increases rapidly in this layer due to the absorption of huge amounts of incoming high energy solar radiation by atoms of nitrogen and oxygen.
