Why are conifers so common in American forests?
tiny-mole [99]

Answer:

Answer is C

Explanation:

Coniferous forests grow in a wide range of climates, from the coldest polar regions to the warmest tropical regions and everything in between. The reason they're so prevalent worldwide is because they take advantage of certain environmental conditions that other trees aren't able to live in as well. Conifer trees are adapted for cold and harsh climates. ... The needle-like leaves are an important adaptation to Conifer trees because they do not accumulate much snow, keeping the weight load mild. Even though Tamarack trees lose their leaves in the winter, they are still subject to some snowfall.

Do you see a connection between wavelength and frequency? Explain.
katrin2010 [14]

Answer:

Wavelength and frequency of light are closely related. The higher the frequency, the shorter the wavelength. Because all light waves move through a vacuum at the same speed, the number of wave crests passing by a given point in one second depends on the wavelength.

Amplitude is the height of a wave which is the brightness of a light or loudness of a sound. So Frequency and Amplitude though are part of a wave are not dependent on each other. Their is no relation between frequency and amplitude.

What is the relationship between DNA, chromosomes, genes, alleles, dominant, recessive, and trait?
larisa86 [58]
Chromosomes are made of condensed coils of DNA. Genes are segments on a chromosome that carry the code for a specific trait. Alleles are contrasting forms of a gene. Dominant means that a particular trait will be visible. Recessive means that a trait will be hidden (unless it is paired with another recessive gene). A trait is how the gene is seen. For example, eye color is a trait.

Optical trapping interferometry

Explanation:

Optical trap is a device which can measure forces or dielectric objects of magnitude of Pico newton or micron.  

In this,  a high focused light beam is used to view objects under the  microscope. It is highly used in molecular and cell biology and biophysics

This methodology has been adapted to sort lipids at cell surface and in activation of kinase in the dendritic cells
