2. Choose a spot of soil that is nearby your home, school, or another area you frequent. If a crime were committed there, what types of materials do you think you'd find in your investigation of the soil? Do you think you would find materials that would be considered individual characteristics?

Answers

It depends on the nature of the crime. There could be foot marks there, or a certain of material found that is usually not found. There could be blood stains, or some genetic samples that could provide for DNA testing. There could be certain chemicals that could lead to identification of the substance used in the crime.

Answer:

You could find any number of things...shoe prints and maybe some tire marks. You might find shell casings, blood, broken glass, dropped items, etc. Some of these could be individual characteristics like the shoe prints, blood, or tire marks.

A DNA template is composed of the following nucleotide sequence: 5'-TACGCATT-3' What is the mRNA transcript for this template?A. 5'-TTACGCAT-3'
B. 5'-AAUGCGUA-3'
C. 5'-UACGCAUU-3'
D. 5'-AATGCGTA-3'
E. 5'-AUGCGUAA-3'

Answers

Answer:

E. 5'-AUGCGUAA-3'

Explanation:

The nucleotide sequence of the template strand specifies the nucleotide sequence of mRNA. Adenine in template strand pairs with uracil base in mRNA, thymine with adenine, guanine with cytosine and cytosine with guanine base. Also, the polarity of the DNA template strand and that of the mRNA is anti-parallel which means that 3' end of the template strand is present opposite to the 5' end of the mRNA. Therefore, a DNA template strand with nucleotide sequence 5'-TACGCATT-3' would code for the following mRNA:

DNA template strand: 5'-TACGCATT-3'

mRNA strand: 3'-AUGCGUAA-5'

Water is drawn upward from the roots through plant tissue to the leaves by

Answers

water exaporates frm the leaves and other parts of the plant above the ground. The evaporation of water from the plant is called ''transpiration''. It occurs mainl through the stomata. However, as quickly as water is lost from the leaves, more water enters the roots and flows up the stem. The water flows up the plant in narrow pipes, rather like capillary tubes. These tubes make up the xylem. The walls of the tubes are made of lignin, which is hard and waterproof. In trees and shurbs the xylem tubes are one of the main components of wood. They do not contain living material and are therefore dead.` Water rises up the stem mainly by being ''pulled'' from above. The ''pull'' is created by the evaporation if water from the leaves. If you stop this by, for example, cutting iff the leaves or blocking the stomata, the flow of water up the stem slows down or stops. The drier the atmosphere, the greater is the rate of transpiration. In very dry wather, water may evaporate from the leaves faster than it is replaced from the soil. The plant then suffers from water shortage. Normally a plant's cells are full of water, and all the cells are pressing against each other within the epidermial covering. This helps to support the plant amd holds the leaves out flat. If a plant runs short of water, the cells lose water and go flabby. The plant then droops. This is called wilting. Plants living in dry places have all sorts of adaptations for not
