Reptiles are a class of vertebrates made up mostly of snakes, turtles, lizards, and crocodilians. The options (A), (B) and (E) are correct.

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.

Answer:

the oxygen concentration decreases only when the air reaches the alveoli, which are the terminal branches of the respiratory system

Explanation:

The human respiratory system is responsible for taking in oxygen-rich air, and they expelling oxygen-poor air. The respiratory system consists of lungs, which helps in the exchange of gases: Oxygen and carbon dioxide.

The statement ''the oxygen concentration decreases only when the air reaches the alveoli, which are the terminal branches of the respiratory system'' explains the change in oxygen concentration of the inspired air

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.

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.

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.

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.

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.

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

2. Fern or lycophytes are sporophytes

3. Seed plants are gametophytes. And that is why they possess both male and female gametes.

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.

Thus A is Odd

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.
