What is the most important part in the respiratory system?
Answers
The lungs.
The lungs are paired, cone-shaped organs which take up most of the space in our chests, along with the heart. Their role is to take oxygen into the body, which we need for our cells to live and function properly, and to help us get rid of carbon dioxide, which is a waste product.

1) What is the difference between traits and characteristics?
2) Can people with different parents still have traits in common?
3) You have a plant with yellow flowers and a tall stem. However, it is wilted because you forgot to water it. Identify which of the described traits of the plant is/are example(s) of those determined by heredity and those determined by the environment.
Answers
Answer:
1) the difference between trait and characteristic is that trait is an identifying characteristic, habit or trend while characteristic is a distinguishable feature of a person or thing.
2) Yes people with different parents still can have traits in common, for example two friends can both have a cleft-chin or a widows-peak.
3) The traits in this situation is the color of the flower (yellow), and the tall stem. But, the environmental part is the wilted part due to the dry environment(the lack of water).

You should be familiar with the drugstore antibiotic ointment Neosporin (Triple antibiotic ointment), which is often thought of as innocuous. Based on your knowledge of antibiotics from Chapter 12 describe the mode of actions of the three antibiotics found in Neosporin (neomycin, polymyxin, and bacitracin), research their side effects, and postulate on why these three antibiotics were chosen.
Answers
Answer: Antibiotics are chemicals which, in low concentrations, can selectively kill or inhibit the growth of most pathogenic bacteria and are not harmful to humans.
Explanation:
Neosporin is a type of antibiotics which is used for the treatment or prevention of mild superficial infections. It consists of three active component, hence the name Triple antibiotic ointment. These active components, their mode of action and side effects include:
--> NEOMYCIN : This is one of the active components of Neosporin which inhibits the protein synthesis of an invading pathogenic bacteria through irreversible binding to the 30 S ribosomal subunit of susceptible bacteria. Their MODE OF ACTION is bactericidal meaning that the effect it has on the protein synthesis inhibits it's growth leading to the death of the bacteria.
SIDE EFFECTS: it can cause irritation, burning, itching, rash redness when applied topically.
--> POLYMYXIN: This is one of the active components of neosporin which attacks the invading pathogenic gram negative bacteria. In its mode of action, is the ability to combine with and disorganise structures of the bacterial cell which are responsible for the maintenance of the osmotic equilibrium of the cell thereby exposing the underlying peptidoglycan layer to lysozyme.
SIDE EFFECTS: Burning, redness, or irritation of the skin may occur.
--> BACITRACIN: This is also one of the active components of Neosporin. In its mode of action, it inhibits bacterial cell wall synthesis. This is achieved by preventing the final dephosphorylation step in the phospholipid carrier cycle, which interferes with the mucopeptide transfer to the growing cell wall.
SIDE EFFECTS: it may cause rash, itching/swelling (especially of the face/tongue/throat).
These three active components of Neosporin are combined to broaden the antibacterial spectrum. This means that at least one of the active components will effectively kill an invading pathogenic bacteria through its unique mode of action.

Cas9 complex scans dsDNA for PAM sequence D. Cas9 unwinds dsDNA E. The programmable part of the guideRNA binds to its complementary sequence F. Cas9 cuts both strands to generate a double strand break
Answers
Answer: a, b, d, c, e, f
Explanation: The steps of Cas9 DNA recognition and cleavage goes in the following order lettered A, B, D, C, E and F. Cas9 recognizes and binds the sgRNA after which it binds to the double stranded DNA. It then unwinds and scans the dsDNA for its protospacer adjacent motif sequence (PAM) and on recognition the sgRNA binds to its complementary sequence followed by cleavage of the DNA at two points. That is how the double stranded break is created.
An animal has 2 genes: 1 for tail length (T) and 1 for head shape (H). Its genotype is TtHh. What are all of the possible gametes that this organism can make?
Answers
Answer:
TH, Th, tH, th
Explanation:
This question involves two genes; one coding for tail length and the other for head shape. According to this question, an organism has the genotype: TtHh.
In accordance to the law of independent assortment, which states that alleles of one gene will segregate independently of one another. The meiotic division of the organism, will occur in such a way that only one allele of each gene is present in any GAMETE.
The possible gametes for the genotype: TtHh are: TH, Th, tH, th
A gardener wanted to know if E-Z fertiliser would be good for his vegetables. He fertilised all his bean plants with E-Z fertiliser but didn’t put any fertiliser on his pepper plants. His beans didn’t do well at all, but he got a good crop of peppers. He concluded that E-Z fertiliser was no good. What are the errors in this experiment? Tick all that apply
A) Not enough subjects
B) Subjects were not similar
C) Conditions were not kept the same
D) The experiment was not reproduced
Answers
Answer:
B) Subjects were not similar
The errors in this experiment are: subjects were not similar and conditions were not kept the same. Hence the correct options are B and C.
Subjects were not similar: The gardener used two different types of plants, beans, and peppers, to test the effectiveness of E-Z fertiliser. Beans and peppers have different growth requirements, nutritional needs, and environmental preferences. By using different types of plants as subjects, the experiment introduces variability and makes it difficult to attribute the outcome solely to the fertiliser.
Conditions were not kept the same: The gardener applied E-Z fertiliser to the bean plants but did not provide any fertiliser to the pepper plants. This difference in treatment introduces a significant confounding factor, making it impossible to isolate the effect of the fertiliser on the bean plants' poor performance.
Hence the correct options are B and C.

You are exploring a rather inhospitable planet, which has seas that are somewhat hydrophobic in nature. Surprisingly, there are living organisms in the seas whose cytoplasm is hydrophobic to a similar degree. These organisms have membranes made primarily of phospholipids arranged in a bilayer. What is the most probable orientation of these phospholipids A.hydrophobic tails facing towards the middle of the bilayer and the hydrophylic heads facing outward
Answers
Answer:
The correct answer would be: hydrophilic heads of the phospholipids face toward the middle of the bilayer with the hydrophobic fatty acid tails facing outward
Explanation:
In normal cases on earth, the lipid bilayer is arranged in a way that the hydrophilic head is present both inside and outside whereas the hydrophobic tail is present in the middle.
But in this case, the seas shows hydrophobic nature it can be predicted that the living organism whose cytoplasm is hydrophobic to the same condition that to interact with the environment the phospholipids bilayer arranged as the polar heads on middle while hydrophilic head on its inside and outside

Answer:
The correct answer is C) wavelength of light and rate of photosynthesis.
Explanation:
The given question is a famous experiment conducted by T W Engelmann which is called the action spectrum experiment. In this experiment when light passes through a prism it splits into its constituent colors splits into violet, indigo, blue, green, yellow, orange and red.
Aerobic bacteria require oxygen for their survival. The green algae produce oxygen during photosynthesis. Engelmann released aerobic bacteria to it. it is found that the bacteria accumulated at the blue and red light because photosynthesis and oxygen release were higher there. So, it establishes the relationship between the wavelength of light and photosynthesis.

Explanation:

The statement that is not true is that there are many systems, or, parts, that work independently. The correct option is C.
What is Earth's system?The application of systems science to the Earth is known as earth system science. It focuses on interactions and 'feedbacks' in particular.
The five Earth systems interact to create the environments we are familiar with.
Everything in the Earth's system can be classified as either land, water, living things, or air. These four components of the system are referred to as "spheres."
They are the "lithosphere" (land), the "hydrosphere" (water), the "biosphere" (living things), and the "atmosphere" (air).
The geosphere is split up into four subsystems: the lithosphere, hydrosphere, cryosphere, and atmosphere.
Because these subsystems interact with one another and with the biosphere, they work together to influence the climate, trigger geological processes, and influence life on Earth.
Thus, the correct option is C.
