Answers

D I think that is the answer

All of the organisms in the domain Archaea are prokaryotes.

Archaea are unicellular organisms with no nuclei, hence are prokaryotes.

Characteristics of Archaea Greek word Archaios means ancient.

They are unicellular organisms that resemble bacteria and have some similarity to eukaryotes.

Hence a third domain Archaea was introduced by Carl Woese based on  ribosomal RNA analysis.

They can live in extreme conditions like higher temperature, higher cold regions etc.

2. Why does the body respond to stimuli?
3. What are some different types of stimuli?
4. What are sensory organs and what type of stimuli do these receptors respond to?
5. What is an explanation of how the information from stimuli is communicated to the brain?
6. What is a description of the two things that can happen when the brain processes the information from stimuli?

Answers

Hello, 3Coli Here!

Here are your answers:

1. What is a stimulus?

Stimulus is a natural body reaction caused by changes in the environment around or inside the organism. This is a response from the brain.

2. Why does the body respond to stimuli?

The body responds to stimuli, because it needs to protect itself.

3. What are some different types of stimuli?

The two main types of stimuli are external stimuli and internal stimuli. External stimuli are reactions triggered by changes that occur outside of the body, while internal stimuli are reactions triggered by changes inside of the body.

4. What are sensory organs and what type of stimuli do these receptors respond to?

The most commonly used sensory organs include Eyes, Ears, Tongue, Nose, and Skin. Eyes respond to light and motion, because they are used to see. Ears respond to sound, because they hear. The tongue is used to taste, so it senses flavors. The nose is used to smell, so it responds to scents. Finally, the skin is used to feel, so it responds to whatever it feels.  

5. What is an explanation of how the information from stimuli is communicated to the brain?

Neuron receptors convert internal and external environments into electrical signals, and then is sent to the brain through nerves.  

6. What is a description of the two things that can happen when the brain processes the information from stimuli?

After the brain receives the signal, it will provide a response. One type of response is that the body will physically react to the change. The second type of response is to avoid the change.

How many amino acids could be specified if codons consisted of two nucleotides instead of three? What problem would this present for an organism making proteins using all 20 amino acids? I need help with the last part i dont undertsand

Answers

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.

16 amino acids could be specified if codons consisted of two nucleotides instead of three.

What do you mean by Codons?

Codons may be defined as an arrangement of three consecutive nucleotides in a DNA or RNA molecule that codes for a specific amino acid.

A mutation may be responsible for such problems that would present for an organism making proteins using all 20 amino acids.

A synonymous mutation means that one base within the codon gets substituted for another. Even though the same amino acid is still produced.  

It changes the sequences of nucleotide bases within the codon, but ultimately the coded amino acids remain the same.

Therefore, it is well described above.

Describe THREE examples of the effect of altitude on animals.(life science)​

Answers

Altitude is an elevation from the sea level. It plays an important role in animals as it affects the respiratory rate, pressure on the cells, and homeostasis.

What is the respiratory rate?

Respiratory rate is the breathing that involves the inhalation and exhalation of gases through the respiratory system. The breathing rate is reduced due to decreases in oxygen transport at a higher altitude which causes fatigue.

At higher altitudes, the pressure is more and in turn, affects the cells as the body also maintains an osmotic pressure to balance the fluid and internal organs. As the altitude increases the temperature drops which affects the homeostasis of the body resulting in more use of energy to keep warm.

Therefore, altitude affects respiration, cell pressure, and homeostasis.

The red star must be moving toward Earth and the blue star away from Earth.


The red star must have a greater surface temperature compared to the blue star.


The blue star must have a greater surface temperature compared to the red star.

Answers

Given what we know, we can confirm that the explanation for the situation described is that the blue star must be moving toward Earth and the red star away from Earth.

How do we explain this?

This has to do with a phenomenon known as the doppler effect. This effect explains how we can perceive a star as red or blue depending on its distance and on whether or not it's moving towards or away from us. When an object moves away from us, the wavelengths of the light it emits are stretched, making the object appear red. However, when it moves towards us, this increases the wave frequency that reaches us and we observe it as blue.

Therefore, we can confirm that the explanation for the situation described is that the blue star must be moving toward Earth and the red star away from Earth.

How can students in the photograph use the net to sample the invertebrates in the river.

Answers

Answer and Explanation:

Macroinvertebrate communities show spatial and temporal variability. Many taxons have more affinity for one specific type of habitat.

There are two principal sampling techniques. Qualitative and cuantitave. Qualitative techniques provide data about the river richness and the relationship between the different taxonomic group's abundance. They allow the obtention of the most representative and abundant taxons, estimates their densities, biomass, and calculates the diversity indexes for each sampling site by period. Nets are needed to sample.

Every possible microhabitat must be sampled. The use of the different sampling elements depends on the substrate.

Hard-substrated sites, such as rocks or wood and organic matter, are sampled using a Surber net. The net is placed counter-current. The substrate must be moved and removed up to 10-15 cm deep, checking that animals and the thin sediment lie on the net. Samplings must be done from downstream to the upstream direction, taking replicates per substrate. Invertebrates must be washed on a strainer. Finally, place each of the samples in a plastic bottle, fixate the material with formaldehyde 4% and take it to the lab for its taxonomic identification.
