Answer:
The answer is "supported and when fruit was removed"
Explanation:
It dated the idea from this laboratory because the distribution of avian beaks differed. If any kind of food available keeps shifting, the frequency of the beak types changes as beaks with beaks is far more suitable for food available. The data in this laboratory confirmed the theory, so because the fruit was removed by birds. These results of this laboratory confirm this idea because the dispersion of pigeons when food was taken was varied.

how would hemoglobin content differ in a person living in philadelphia compared to someone living in denver
Answer:
The correct answer is - the difference in altitudes.
Explanation:
The hemoglobin in the person of Denver who lives at a higher altitude than the person who lives in Philadelphia will be much higher. This is due to the fact that at higher elevation or altitude atmospheric pressure decreases that causes hemoglobin to stick to the RBCs and that results in less oxygen level in the body.
To compensate for this low level of oxygen levels hemoglobin content need to be higher in people living at a higher elevation.

The discovery of a buried crater (about 200 km across) near Chicxulub, Mexico.
What is extinction?
Extinction is defined as the disappearance of an organism or a group of organisms as a result of environmental factors or changes in the members' evolutionary processes.
It can also be defined as an evolutionary process that causes a species or population to go extinct.
When there are no longer any living members of a certain animal or plant species anywhere in the globe, the species has become extinct.
Generally speaking, species disappear for the following reasons:
Genetic and demographic phenomena.Habitat destruction in the wild.Species introduction that are invasive.Global warmingHunting and illicit trade.Thus the discovery of a buried crater (about 200 km across) near Chicxulub, Mexico.

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.

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.
list few points on the importance of sun in power supply.
Answer:
The sun provides more than enough energy to meet the whole world's energy needs, and unlike fossil fuels, it won't run out anytime soon. As a renewable energy source, the only limitation of solar power is our ability to turn it into electricity in an efficient and cost-effective way.
Answer:
Nothing is more important to us on Earth than the Sun. Without the Sun's heat and light, the Earth would be a lifeless ball of ice-coated rock. The Sun warms our seas, stirs our atmosphere, generates our weather patterns, and gives energy to the growing green plants that provide the food and oxygen for life on Earth.
Why does the thermosphere increase in temperature as altitude increases?
Answer:

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.
