pantera1 [17]

Answer:

A lethal mutation, thereby the resulting phenotype is not observed .

Explanation:

Lethal mutations are the result of genomic changes that may be lethal in certain conditions. In genetic research, this type of mutation has shown to be very useful in analyzing gene function (i.e., genes whose protein products are key for the survival of the organism in question), and they are perfect gene markers. In bacteriophages, for example, temperature-sensitive mutants of phage T4 that can not grow at temperatures higher 42°C have been identified (Edgar & Lielausis 1964).

Damm [24]

Given: The systolic arterial blood pressure observed for 20 dogs is normally distributed with a mean of 152 mm of mercury (Hg) and a standard deviation of 18 mm of Hg.  

To find: P(100 < 152)

Method: Calculation of Z-Score followed by the probability or area of the bell curve at X = 100.

Solution:

Mean u = 152, std s = 18

Z score = \frac{X-u}{s} = \frac{100-152}{18} = -2.89

The value of P(100<152) is calculated by looking at the value of Z in the Z score for the standard normal distribution given in the image.

P(Z=-2.89) = 0.0019

The P(Z = -2.89) corresponds to the area in the left tail of the bell curve.

Thus the probability of 100 mm Hg blood pressure is 0.0019.

Describe how each of Newton’s laws may be observable during a car trip.
aleksandrvk [35]
According to Newton's first law, an object in motion continues in motion with the same speed and in the same direction unless acted upon by an unbalanced force. Any passengers in the car will also be decelerated to rest if they are strapped to the car by seat belts. Also if a car was going straight but another car (unbalanced force) bumps into it causing the motion of the car to change.

A woman cannot produce several types of lipases and amylases. name a problem
Sholpan [36]

Answer:

Lipases and Amylases:

Lipases are a class of digestive enzyme produced by the pancreas. These enzymes are responsible for breaking down fatty acid chains into their smaller sub units so that they can be absorbed by the body. Amylases are a class of digestive enzyme produces by the salivary glands in the mouth and the pancreas. These enzymes breakdown carbohydrates into smaller sub units so they can be absorbed.

Explanation:

because of excessive amount of protease this problem may have protein lack causing various problem in body
