Answer:
C. P -› F1 -› F2
Explanation:
In genetics and breeding, the following symbols represents the following:
P => parental
F1 => First filial generation
F2 => Second Filial generation
The crossing of two parent plants (P) produces offspring that is tagged the first filial generation (F1). The next cross involving the F1 offspring produced second filial generation (F2).
Therefore, the correct sequence is:
P -› F1 -› F2

A current challenge for doctors involves the bacterial strain Clostridioides difficile, which no longer responds to traditional antibiotic treatments.
Which of the following best explains why this particular strain of bacteria is resistant to antibiotic treatment?
A. Mutations creating new alleles occur more frequently in this species of bacteria than in other species.
B. Crossing over during meiosis increased genetic variability in the bacteria.
C. The bacteria have high genetic variability and high reproductive rates.
D. The bacteria are able to recognize and destroy the antibiotics by breaking them down extracellularly
Answer:
C. The bacteria have high genetic variability and high reproductive rates.
A current challenge for doctors involves the bacterial strain Clostridioides difficile, which does not respond to traditional antibiotics because bacteria have high genetic variability and high reproductive rates, which are present in Option C.
What causes such rapid antibiotic resistance?Antibiotic resistance occurs when bacteria develop the ability to survive against the antibiotics, and this can happen for several reasons, including overuse and improper use of antibiotics as well as the natural ability of bacteria to adapt and evolve because they can reproduce rapidly and generate many offspring in a short period of time that can possess the gene that destroys the antibacterial drugs.
As a result, a current challenge for doctors involves the bacterial strain Clostridioides difficile, which does not respond to traditional antibiotics because bacteria have high genetic variability and high reproductive rates, which are present in Option C.

14) When oxygen is released as a result of photosynthesis, it is a direct by-product of
A) splitting water molecules.
B) electron transfer in photosystem I.
C) electron transfer in photosystem II.
D) chemiosmosis.
E) reducing NADP-.
Answer:
A) splitting water molecules I believe
When oxygen is released as a result of photosynthesis, it is a direct by-product of splitting water molecules.
PHOTOSYNTHESIS:
Photosynthesis is the process whereby green plants obtain their food (glucose) using energy from sunlight. Photosynthesis occurs in two stages namely: light dependent reaction and light independent reaction. In the light dependent reaction, chlorophyll molecules absorb light and the released electron is used to split water molecules into hydrogen and oxygen gas. Therefore, the release of oxygen gas is a direct byproduct of the splitting of water molecules called photolysis.Learn more at: https://brainly.com/question/25027435?referrer=searchResults

Which of the following are techniques besides molecular clocks used by scientist to calculate the rate at which a stretch of DNA changes? (Choose all that apply)
•comparison of human behaviors
•carbon dating of fossils
•comparison of blood proteins
•comparison of homologous structures
Answer:
B and D
Explanation:
Human behaviors do not affect the entire evolution of every lifeform that has existed, therefore, A is FALSE
Carbon dating is commonplace in figuring out how old a lifeform could be, therefore, B is CORRECT
Blood proteins are commonly known to not last long and decompose fast, so fossilization of blood tends to not happen, plus it's next to impossible to tell what species had that genetic data, therefore, C is FALSE
For D, I kinda forgot most of my explanation, but I remember that it's correct, as I got the question correct on the assignment.
The carbon dating of fossils and comparison of homologous structures are techniques besides molecular clocks used by scientist to calculate the rate at which a stretch of DNA changes.
So, option B and D are correct one.
Human behaviors do not affect the entire evolution of life of organism that has existed, therefore, A is FALSE
Carbon dating is commonplace in figuring out how old a life of any organism, therefore, B is CORRECT
Blood proteins are commonly known to not last long and decompose faster, so fossilization of blood tends to not happen, plus it's next to impossible to tell what species had that genetic data, therefore, C is FALSE
By comparing of homologous structures we determine nucleotide sequence exchanged between two similar or identical molecule of DNA. So, option D is correct

Answer:
esophagus
Explanation:
the esophagus is the pipe/muscle that leads to your stomach
Choking on food is most likely caused by an interference with the proper functioning of the oesophagus.
What is oesophagus?
The digestive system, sometimes known as the gastro-intestinal tract, includes the oesophagus (gullet) (GI tract). An oesophageal tube is made of muscles. It joins the mouth with the stomach.
The oesophageal walls contract together as you swallow food (contract). This causes the food to travel from the mouth to the stomach.
The diaphragm is a layer of muscle located below your lungs. It facilitates breathing. The majority of your oesophagus is located in your chest above the diaphragm.
Therefore, Choking on food is most likely caused by an interference with the proper functioning of the oesophagus.

30 g of ammonia nitrate and nitrite are added to a soil sample. Predict whether these concentrations would increase decrease or stay the same if ammonia nitrifying bacteria were added to the sample 30 g of ammonia nitrate and nitrite are added to a soil sample. Predict whether these concentrations would increase decrease or stay the same if ammonia nitrifying bacteria were added to the sample
Answer:
See explanation
Explanation:
Nitrifying bacteria convert the most reduced form of soil nitrogen, ammonia, into its most oxidized form, nitrate(Science direct).
Nitrifying bacteria converts ammonia to nitites and finally to nitrates in the soil.
Hence, when 30 g of ammonia, nitrate and nitrite are added to a soil sample in the presence of nitrifying bacteria; the concentration of ammonia decreases over time while the concentration of nitrite and nitrate increases over time.
ammonia stays the same
nitrates decrease
nitrates increase

Cross two pink snapdragons. What is the genotypic and phenotypic probability of such a cross?
Answer:
Genotypic probability = 1RR: 2Rr: 1rr
Phenotypic probability = 1Red: 2Pink: 1white
Explanation:
This question involves a single gene coding for skin color in snapdragon plants. The alleles are incompletely dominant over one another and hence, produce an intermediate pink phenotype.
According to this question, two pink/heterozygous snapdragons were crossed i.e. Rr × Rr. Each parent will have gametes R and r. Using these gametes in a punnet square (see attached image), the following proportion of offsprings will be produced:
Genotypic probability = 1RR: 2Rr: 1rr
Phenotypic probability = 1Red: 2Pink: 1white

Which part of the nucleotide codes for out traits?
The nitrogenous bases which are the part of nucleotide codes for out traits. Nitrogenous bases are of two types: Purines and Pyrimidines.
What are Nitrogenous bases?Nucleobases are also known as nitrogenous bases. These are the nitrogen-containing biological compounds which form nucleoside units, which, in turn, are components of the nucleotides, with all of these monomeric units that are constituting of the basic building blocks of nucleic acids.
The ability of the nitrogenous bases to form base pairs and to stack one above the another leads directly to a long-chain helical structure such as ribonucleic acid (RNA) and deoxyribonucleic acid (DNA) molecules. Five nitrogenous bases include adenine (A), cytosine (C), guanine (G), thymine (T), and uracil (U). They function as the fundamental units of the genetic code in living organisms, with the bases A, G, C, and T being found in the DNA molecule while A, G, C, and U are found in the RNA molecule.
