8. That beeping is loud and penetrating.
9. You don't notice the feel of your clothes on your skin.
10. The flower garden has many colors and shapes.
Answer:
1. perception
2. perception
3. sensation
4. sensation
5. sensation
6. perception
7. perception
8. perception
9. sensation
10. perception
Explanation:
Sensation and perception are two processes which look very similar to each other but are a different process.
Sensation involves the sensory organs of the body which can sense the physical world around us whereas perception involves the process which involves the brain as it organizes and interprets the sensory input.
1. perception- Taste is considered the perception because the taste is interpreted in the brain.
2. perception- the sensory receptors send the signals about roughness to the brain where the brain tells that the substance has roughness.
3. sensation- playing a song in the grocery store is an example of sensation as the person has just listened to the music and is not interpreting whether it is good or bad.
4. sensation- smell involves the sensory receptors but the taste of the smell is perception therefore is the smell is considered a sensation.
5. sensation- the smell is sensation therefore sensation is correct.
6. perception- perception involves the memory, experience and emotions therefore recognizing Bob is considered perception.
7. perception- reminding of soup involves memory, therefore, is considered perception.
8. perception-loud sound involves the brain, therefore, is a perception
9. sensation-feel of cloth is by sensory receptors but the type of feel will be perception.
10. perception-colour and shape are recognised by the brain and depends on memory, therefore, are perception.
In the hydrophobic core of a folded protein, there are three alanine and five phenylalanine residues that are buried, and do not interact with water.
Assume:
In solution, waters can take on seven energetically equal states.
Two waters are ordered around each alanine in the unfolded state.
Six waters are ordered around each phenylalanine in the unfolded state.
In the unfolded state, waters are ordered around alanine or phenylalanine residues and can take on only two energetically equal states.
What is the difference in the entropy of the water due to the burying of these residues as the protein folds?
Answer:
The difference In The entropy of The western due to The burying of these residues as the protein folds is 291J/K
Explanation:
According to the data we know that
total water molecule = 2 * number of Ala + 6 * number of phenylalanine
replacing we get
2 * 2 + 6 * 4 = 4 + 24 = 28
total water molecule = 28
next step
S folded = Rln728
we replace the data and we get that
8.31 * 28 * ln7 = 452J • K –1 • mol –1
S unfolded = Rln228
we replace the data and we get that
8.31 * 28 * ln2 = 161J • K –1 • mol –1
∆ S = S folded - S unfolded = 452-161 = 291J / K

In chickens, comb shape is determined by genes at two loci (R, r and P, p). A walnut comb is produced when at least one dominant gene R is present at one locus and at least one dominant gene P is present at a second locus (genotype R_ P_). A rose comb is produced when at least one dominant gene is present at the first locus and two recessive genes are present at the second locus (genotype R_ pp). A pea comb is produced when two recessive genes are present at the first locus and at least one dominant gene is present at the second (genotype rr P_). If two recessive genes are present at the first and the second locus (rr pp), a single comb is produced. Give genotypes for comb shape of the parents in the following cross: Rose crossed with pea produces 20 walnut offspring.
a. RR PP × rr pp
b. RR Pp × rr pp
c. Rr PP × rr pp
d. Rr Pp × rr pp
e. Rr pp × rr pp
Answer:
in the obtained options, there is no dominant gene for the crossed pairs, therefore, no answer would be correct, however, when assigning a dominant character to the P gene, the correct answer would be:
E. Rr pp *rrPp
Explanation:
According to the information obtained we deduce:
Comb shape is produced by R and P
Comb of walnuts with an R or a P
Pink comb: 1 dominant P and R at the first locus and 2 recessive at the next locus
Pea comb: 2 recessive at the start and one dominant in the next position
1 single comb: 2 recessive at both loci
Rr pp × rr Pp will produce from the interbreeding: 2 walnuts, 1 single and 1 pea offspring.
We deduce that for the pink comb the genotype is: Rrpp
and for the pea comb it is rrPp
Rr pp × rr Pp generates crosslinks containing RrPp, rrPp, rrpp as children in a 2: 1: 1 ratio.

Under physiological conditions, a polypeptide folds up into secondary structure. what are the most common secondary structure elements?
Answer:
The folding of polypeptide begin during translation of the polypeptide chain. Amino acids interact with each other to form three dimensional tertiary structure and secondary structure elements formed spontaneously as an intermediate before the formation of tertiary structure.
There are two common secondary structure elements formed that are alpha helices(α helix) and beta pleated sheets ( β pleated sheet). Both the structures are attcahed by a hydrogen bond which is present between amino hydrogen and carboxyl oxygen atoms in the peptide backbone.
Hence, the two common elements of secondary structure are alpha helices and beta sheets.

Reptiles are a class of vertebrates made up mostly of snakes, turtles, lizards, and crocodilians. The options (A), (B) and (E) are correct.
What are the characteristics of reptiles?Reptiles, as most commonly defined are the animals in the class Reptilia, a paraphyletic grouping comprising all sauropsids except birds. Living reptiles comprise turtles, crocodilians, squamates and rhynchocephalians.
Moreover, the major groups of living reptiles—the turtles (order Testudines), tuatara (order Rhynchocephalia [Sphenodontida]), lizards and snakes (order Squamata), and crocodiles (order Crocodylia, or Crocodilia)—account for over 8,700 species.
Therefore, the name "reptile" comes from Latin and means "one who creeps". All living reptile species are cold blooded, have scaly skin, and lay cleidoic eggs. They excrete uric acid (instead of urea), and have a cloaca. A cloaca is a shared opening for the anus, urinary tract and reproductive ducts.

Determine whether each characteristic describes a nonvascular plant or a vascular plant.
are small when fully grown
are always seedless
can be large when fully grown
normally live in moist environments
may have seeds
can live farther from water
Answer:
Vascular plants:
Can be large when fully grown.
May have seeds.
Can live farther from water.
Nonvascular plants:
Are small when fully grown.
Are always seedless.
Normally live in moist environments.
Explanation:
Plants can be classified regarding their flowering and their vasculature. When taking vasculature into consideration, they can be classified as Vascular Plants or Nonvascular plants.
Vascular plants have separate tubular tissues that are used to transport food and water, while nonvascular plants do not have these tissues. For this reason, nonvascular plants have a much harder time controlling the water inside them, and that's why they need to live in humid environments in order to survive. Vascular plants, on the other hand, can live in places farther from water.
Since they do not have vasculature, nonvascular plants are short in length, which makes it easier to survive considering the lack of tubular structures made for transport that vascular plants have.
Nonvascular plants do not have a vasculature, which means they do not have roots, stems, leaves nor seeds.
Which statement regarding lung cancer is correct?
A. Individuals with emphysema are not at risk for lung cancer.
B. Lung cancers are not aggressive.
C. More Americans die from lung cancer than any other form of cancer.
D. Only smokers will develop lung cancer.
Answer:
The correct answer is: C. More Americans die from lung cancer than any other form of cancer.
Explanation:
Lung cancer is one of the most aggressive cancers in the world, and is also the cancer that kills the most people in America every year (it is estimated that almost 140,000 Americans die from this cancer every year).
Emphysema is a chronic pulmonary disease that occurs when the air sacs in the lungs, called alveoli, enlarge and get damaged. This condition is mostly caused by smoking, and makes up a very significant risk factor for lung cancer.
Even when smoking makes up a huge risk factor for developing this and other types of cancer, non-smokers can develop lung cancer as well.
Answer: A is wrong, emphysema is not a risk factor for lung cancer. Lung cancer is primarily due to exposure to tobacco smoke and carcinogens in the smoke. Emphysema is due to loss of alveolar surface areas due to destruction of alveolar surfaces.The results is loss enough surface area for oxygen and C02 exchange in the lungs.
Generally D is wrong lung cancer is not limited to smokers only, smoking just increases it risk. Passive smokers can also develop cancer.But 45-50 of lung cancers is due to smoking. Beneze inhale from rubber industries,and asbestos industries are other places where Lung cancer can be developed after exposure.
A type of lung cancer can be agressive.(SCLC) While others can be slow.
C is correct.

15. Knowing that the genetic code is almost universal, a scientist uses molecular biological methods to insert the human B-globin gene into bacterial cells, hoping the cells will express it and synthesize functional B-globin protein. Instead, the protein produced is non-functional and is found to contain many fewer amino acids than does B-globin made by a eukaryotic cell. Explain why.
Answer:
The genetic information of living organisms is sequenced in DNA, which allows inheritable factors to be transmitted with each replication process. Proteins play a very important role by intervening in their metabolism during the translation and transcription of information. .
eukaryotic and prokaryotic organisms have different evolutionary sequelae that are reflected in the mechanisms they use for DNA translation, such as in the initial stages, lengthening and termination of sequencing, these differences are imparted by the order of the genes, the ribosome and its structural form and the promoter sequences.
In this way we can conclude that although the eukaryotic genes enter into a bacterium, the type of information that they take may arrive incomplete and this may generate subsequent defects for their operation, but there may be processes that guarantee a better transfer of information with the use of genetic engineering and enzyme management to introduce different bacterial genetic expressions with eukaryotic genes.
Eukaryotic cells like humans and prokaryotic cells like bacteria vary in central dogma methods.
The generative data of an organism is stored in the sequenced DNA that gets transferred during the process of replication.
The DNA transcription and translation process in prokaryotes and eukaryotes differ like the steps concerned in the beginning and the termination of the arrays are defined by various sets of genes in both types of organisms.
The promoter, ribosomes and the structural genes make both the organism distinct from each other.
So, when the eukaryotic gene intrudes bacteria may lack some data that can get misinterpreted and the resulted proteins or amino acids will differ.

Describe the trends that you see in the evolution of land plants in terms of: gametophyte or sporophyte dominance size and independence (whether or not it can live on its own) of the gametophyte or sporophyte Make sure that you identify those two traits for each of the major land plant groups : 1) "Bryophytes" 2) Ferns and Lycophytes 3) Seed Plants (Gymnosperms and Angiosperms) New piece of information: diploid organisms have higher survival under high ultraviolet radiation environments (i.e. on LAND!) than haploid organisms. Using the trends you observed and the new information above, make an inference: WHY do we observe these trends in the land plants? (In other words, how might higher survival of diploid organisms under high UV conditions explain the trend you observe.)
Answer:
Explanation below.
Explanation:
Gametophytes are plants that reproduce not by spores but by gametes, that is male and female gametes.
Sporophytes are the plants that make use of spores as the means of reproduction. This means that they produce spores.
1. Bryophytes are sporophytes
2. Fern or lycophytes are sporophytes
3. Seed plants are gametophytes. And that is why they possess both male and female gametes.

Question 9
What does it mean if the G2 checkpoint fails during cell Division
Answer:
If the checkpoint mechanisms detect problems with the DNA, the cell cycle is halted, and the cell attempts to either complete DNA replication or repair the damaged DNA.
Explanation:
The G2 DNA damage checkpoint is an important cell cycle checkpoint in eukaryotic organisms that ensures that cells don't initiate mitosis until damaged or incompletely replicated DNA is sufficiently repaired. Cells that have a defective G2 checkpoint enter mitosis before repairing their DNA, leading to apoptosis or death after cell division.
