Answer:

A

Explanation:

Took test on Edge.

Answer 2

Material Safety Data Sheet (MSDS) contains information related to occupational safety and health. The MSDS provides knowledge on the safe handling of chemicals. Thus, option A is correct.

What is MSDS?

Material Safety Data Sheet (MSDS) is the data safety sheet that states the rules and details of handling and using the laboratory chemicals that are related to health. It is of great importance as it allows the learning of chemical hazards.

Before entering the lab and using the chemicals one should read the MSDS book so to get aware of the handling and precautions that have to be taken while performing any experiments. To work safely one should know its danger and should be prepared for emergencies.

Therefore, the MSDS provides knowledge on the handling of hazardous chemicals.

n your lab you are studying the genome of venomous rattlesnakes to find the gene which codes for their venom glands. You have two rattlesnakes, one rattlesnake has a mutation but can still produce venom. You compare his DNA to a normal rattlesnake. What type of mutation has occurred? Normal: AATCGCTACGCACGTCAG Mutated: TATCGCTACGCACGTCAG

Answers

Answer:

There are no options but the kind of mutation that occurred by carefully observing both sequences is:

POINT SUBSTITUTION MUTATION

Explanation:

Mutation is any change, whether small or big, in the nucleotide sequence of a gene (DNA). Mutation occurs from time to time in an organism either by a mistake during DNA replication or induced by a mutagen (mutation-causing substance). Mutation can be of different types depending on the effect on the mutant.

In this case of comparing the DNA sequence two rattle snakes, the sequences of the two snakes are:

Normal: AATCGCTACGCACGTCAG

Mutated: TATCGCTACGCACGTCAG

By carefully observing the two DNA sequences, one would realize that the only difference in the two sequences is the first nucleotide base. That is, in the normal sequence, th first base is Adenine (A) while in the mutated sequence, the first base is Thymine (T).

This type of mutation that involves only one nucleotide base is called POINT MUTATION. It can also be noticed that base "A" was changed "T". Hence, this is a type of SUBSTITUTION MUTATION because a single base was replaced by another in the sequence.

Discuss Connell and Slatyer three mechanisms of succession. Start your answer with a definition and an example of what is succession, and describe how succession begins.

Answers

Answer:

Facilitation, tolerance and inhibition models

Explanation:

J. H. Connell and R. O. Slatyer stated three different ecological succession models that explain how species composition may change by the effects of disturbances in the ecosystem. These models are as follow:  

1- Tolerance model: in this model, the new species don't affect the growth and success of existing species, thereby the process of succession is purely associated with life-history strategies.

2- Facilitation model: only 'ideal traits' found in colonizing species lead to the initial succession. These ideal traits include for example effective mechanism of dispersal, water storage tissues to survive in dry regions, long-term seed dormancy, etc.

3-Inhibition model: Species that appeared during early succession are capable of inhibiting growth of species appeared in later stages, as well as reduce colonizing species abundance.

Answer:

This question lacks options, options are:

A) cerebral cortex.

B) basal nuclei.

C) sensory pathways.

D) motor pathways.

E) All of the answers are correct.

The correct answer is E.

Explanation:

The cerebral cortex processes and filters its information before passing the most relevant aspects to other regions of the brain. Some of these brain regions, in turn, send information back to the cortex. These loops, known as 'feedback systems', are considered essential for the functioning of cortical networks and their adaptation to new sensory information. Neural circuits must first assess the importance of incoming sensory information and then refine how it is processed in the future. Positive feedback, triggered with the purpose of amplifying the response to the initial stimulus, can be compared to a chain reaction or a vicious circle. Few are the functions regulated by this mechanism; rather it is triggered in pathological situations. It is the system by means of which the organism very rarely regulates any of the bodily functions under normal conditions, making the initial stimulus to be maintained and even increased. This type of mechanism is predominantly present in pathological situations: Its constitutive elements are: stimulus, receptor, afferent pathway, integrating center, efferent pathway, effector and response. The response does not have the ability to satisfy the initial stimulus.

What fluid balance disorder would be expected with these symptoms?

Answers

Answer:

Lack of Antidiuretic hormone.

Explanation:

Antidiuretic hormone is a type of hormone which is responsible for controlling urination. It is produced in hypothalamus which is a part of a brain. Antidiuretic hormone is responsible to tell the kidney how much water in the body should be conserve to avoid dehydration. If less antidiuretic hormone is produced by the body so more urine is produced. Frequent urination is also occurs due to Diabetes insipidus.

If pattern of inheritance is complete dominance what would you expect when a red and yellow fish were crossed

Answers

In the question, it is not mentioned that which fish is dominant and recessive, so lets consider red fish is dominant and yellow fish is recessive.

Answer:

In complete dominance, the dominant trait completely masks the recessive trait and the offspring shows dominant characters only.

When a red and yellow fish were crossed, the pattern of inheritance is complete dominance which means the offspring would have dominant characters.

As we considered, red fish has dominant trait so the offspring produced will also have red color as yellow color (recessive) will be masked by dominant red color fish.
