<span>If a scientist were to view cancer cells under a microscope, he would probably notice several differences compared to other cells. For one, cancer cells develop abnormally shaped glands. They are usually oblong and extended compared to healthy cells. Also, cancer cells are found in clumps, so that would be a characteristic easy to see with a microscope.</span>
Answer:
λ = 37 nm
Radiation is in the ultra violet region.
Explanation:
Given data:
Energy of photon = 5.44 × 10 ⁻¹⁸ J
Wavelength of photon = ?
Solution:
E = h.c / λ
λ = h. c/ E
λ = 6.63× 10⁻³⁴m² kg/s × 3×10⁸ m/s / 5.44 × 10 ⁻¹⁸ Kg m²/s²
λ = 19.89 × 10⁻²⁶ kg. m³ /s² / 5.44 × 10 ⁻¹⁸ Kg m²/s²
λ = 3.7 × 10⁻⁸ m
m to nm conversion.
λ = 3.7 × 10⁻⁸m ×10⁹ nm / 1m
λ = 37 nm
Radiation is in the ultra violet region because the rage of UV is 1 nm - 400 nm.
Answer:
ER → ER-to-Golgi transport vesicles → Golgi cisternae → secretory or transport vesicles →cell surface (exocytosis) (see Figure 17-13). Small transport vesicles bud off from the ER and fuse to form the cis-Golgi reticulum.
Answer:
genetic changes among and within populations
Explanation:
Microevolution occurs when there are changes in gene frequency within a population over a short period of time. Microevolution specifically refers to changes within a population, a population being a group of organisms that breed with each other.
hope this helps :)
Even though New Zealand has a smaller population than Australia, it has a greater population density because it covers a much smaller area. Australia’s population is approximately five times larger than New Zealand’s while the area Australia covers is approximately 30 times larger than the area New Zealand covers.
