In the soybean respiration experiment, why were glass beads added in the non-germinating seed tube?

Biology
1 answer:
Alborosie3 years ago
5 0

Answer:

Explanation:

The result was a decrease in gas volume within the tube, and a related decrease in pressure in the tube. The respirometer with just the glass beads served as a control, allowing changes in volume due to changes in atmospheric pressure and/or temperature.

The purpose of the beads is to ensure that each respirometer is uniform in volume. The vial with glass beads alone will permit detection of any changes in volume due to atmospheric pressure changes or temperature changes.

the muscular system and the skeletal system are two different organ systems, but they’re often referred to jointly as the muscul
Lana71 [14]
The muscular system is responsible for the movement of the human body. Attached to the bones of the skeletal system are about 700 named muscles that make up roughly half of a person's body weight. Each of these muscles is a discrete organ constructed of skeletal muscle tissue, blood vessels, tendons, and nerves.

How many amino acids could be specified if codons consisted of two nucleotides instead of three? What problem would this present
Greeley [361]

Answer:

This could result in a mutation.

Explanation:

A change in the DNA can affect the work of cells because it can cause a mutation; it can be a good mutation or bad. The three main mutations that occur are Insertion, Deletion and Substitution. Insertion is when DNA base(s) are added in, Deletion is when DNA base(s) are removed. Lastly, Substitution is when DNA base(s) are switched on. All of these mutations can have effects. These effects are Silent effect, Missence, and Nonsense. Silent effect is a mutation that does not change the sequence of amino acids in a protein. Missence is a mutation that causes the sequence of amino acids to change. This can cause incorrect protein folding and protein malfunction. Nonsense is a mutation that causes an early stop codon. This effect leads to a protein that is too small. Also a Frameshift can occur. Framshift is when the reading of a frameshift is moved over by one or more bases such that every subsequent amino acid changes. An example of a frameshift is THE CAT ATE THE RAT. If you insert an A at the Beginning this happens ATH ECA TAT ETH ERA T. IN Conclusion there are two Mutations that also play a role in this Point Mutation and Chromosomal Mutaion. Point Mutation is when a single DNA base is either substituted, inserted or deleted from the sequence. Chromocomal Mutation is when large pieces of a chromosome or an entire chromosome is either substituted, inserted or deleted.

A connective tissue disorder in which dense irregular connective tissue fails to form properly will affect the formation of
andrezito [222]

Inability of dense irregular connective tissue to form properly will affect the formation of organs and the skin.

<h3>What is connective tissue?</h3>

Connective tissue is the tissue that provides supports, and gives structure to other tissues and organs in the body.

Connective tissue is made up of cells, elastic fibers, and collagen.

The dense irregular connective tissues are distributed throughout the body are important in the formation of the skin, the eyes and walls of organs.

Inability of dense irregular connective tissue to form properly will affect the formation of organs and the skin.
