To create a simulation of photosynthesis in a forest of 50,000 maple trees, a scientist needs to determine the average number of leaves on an actual maple tree. Which of the following is the best course of action for establishing this parameter?A. Determine the average number of leaves for 10 randomly selected maple trees.
B. Choose a value at random to represent the average number of leaves on a tree.
C. Count the number of leaves on a single tree and assume all trees are the same.
D. Divide the total number of leaves on all the trees in a forest by 50,000.

Bio-metrics are automated methods of recognizing a person based on a physiological or behavioral characteristic. Among the features measured are face, fingerprints, hand geometry, handwriting, iris, retinal, vein, and voice.

The scanner uses a light-sensitive microchip, either a CCD, charge-coupled device, or a CMOS image sensor, to produce a digital image. The computer analyzes the image automatically, selecting just the fingerprint, and then uses sophisticated pattern-matching software to turn it into a code.

The technique relies on capturing an optical image, essentially a photograph, and using algorithms to detect unique patterns on the surface, such as ridges or unique marks, by analyzing the lightest and darkest areas of the image.

Answer:

A disease or infection of the inner ear.

Explanation:

The inner ear infection or inner ear disease can be described as inflammation of inner parts or ear, which are responsible for the hearing and balance, such as swimmer's ear (also known as otitis externa).

Swimmer's ear represents an ear infection, characterized by inflammation or irritation of ear canal, swelling and pain in ear canal, moist earwax, and decreased hearing.

Thus, the correct answer is option). 'a disease or infection of the inner ear.'

Answer:

b. As invasive species increase, it causes biodiversity to decrease

Explanation:

Invasive species refers to those species of organisms that are foreign (non-native) to a particular environment or habitat with the tendency to outgrow and outcompete the native species in that habitat. Due to their fast reproductive and growth rate, they tend to diminish the population of native species by using up the available nutrients.

Biodiversity is the richness of organism species on Earth. When invasive species increase in a particular habitat or ecosystem, they cause the biodiversity in that habitat to decrease because they tend to take charge and dominate, causing harm to every other species. Hence, As INVASIVE SPECIES INCREASE, it causes BIODIVERSITY TO DECREASE
