Certain species of blind fish living in perpetual darkness in the ocean depths have evolved from ancestors that could see. Research indicates that the brain centers for vision in these fish is degenerating, whereas the brain centers controlling other senses are enlarging. What might be the MOST probable reason for the loss of vision in these fish
Answer:
Explanation:
Evolution for lack of light. If there is no reason for it you lose the ability but it strengthens other senses. It's compensation. The need to tell if the temperature has increased because of something nearby or ability to feel miniscule movement will increase to compensate for that lack of sense.

Moving the magnet faster would not produce more electricity when a magnet is moved.
What is magnet?A substance or thing that creates a magnetic field is called a magnet. The most noteworthy characteristic of a magnet—a force that pulls on other ferromagnetic elements, such as iron, steel, nickel, cobalt, etc.—as well as the ability to attract or repel other magnets—is caused by this invisible magnetic field.
An object made of a substance that has been magnetized and produces its own persistent magnetic field is referred to as a permanent magnet. A common example is a refrigerator magnet used to keep notes on the door of the refrigerator.
Ferromagnetic materials are those that can be magnetized and are also those that are powerfully drawn to a magnet (or ferrimagnetic). These comprise some naturally occurring materials as well as the metals iron, nickel, and cobalt as well as their alloys.
Therefore, Moving the magnet faster would not produce more electricity when a magnet is moved.

Neosporin is an antibacterial ointment used in the prevention and fighting of infection and in speeding the healing of wounds. Determine if this would be considered part of the first line of defense and which barrier category it would belong to. Explain your answers.
Answer:
Explanation:
The use of ointment for bacterial treatment does not fall into the first line of defence.
The first line of defence are physical (skin,tears, mucus) and chemical barriers( white blood cells also called neutrophils) which are prepared to defend the body against infection. The skin which is one of the first line of defence is a barrier that prevents entry of microorganisms the body. When the first mechanism is not effective especially for pathogens then the second mechanism is activated to get rid of the microorganism.
The use of ointment does not belong to any barrier or defence mechanism this is because it is not a natural way of getting rid of microorganisms within the body system.

The R and S loci are 35 m.u. apart. If a plant of genotype is selfed, what progeny phenotypes will be seen and in what proportions
Complete question:
The R and S loci are 35 m.u. apart. If a plant of genotype RS/rs is selfed, what progeny phenotypes will be seen and in what proportions
Answer:
R-/S- = 0.6052 R-/ss = 0.1443rr/S- = 0.1443rr/ss = 0.1056Explanation:
Available data:
R-S are 35 mu apartCross: RS/rs x RS/rsFirst, we need to recognize the parental gametes and the recombinant ones.
Cross:
Parentals) RS/rs x RS/rs
Gametes) RS Parental ⇒ Equal to the parental genotype
rs Parental ⇒ Equal to the parental genotype
Rs Recombinant ⇒ Product of recombination
rS Recombinant ⇒ Product of recombination
We know that genes are 35 MU apart from each other. The map unit is the distance between the pair of genes for which every 100 meiotic products, one of them results in a recombinant one.
To calculate the recombination frequency, we have to know that 1% of recombinations = 1 map unit = 1cm. And that the maximum recombination frequency is always 50%.
According to this information, if 1 MU = 1% recombination frequency, then
35MU --------- 35% recombination frequency = 0.35
Now, let us calculate the frequency of each gamete type.
35 map units = 35 % of recombination in total
= % Rs + % rS
= 17.5% Rs + 17.5% rS
Now, if the recombination frequency equals 35% then the parental frequency is 100% - 35% = 65%
65 % parental frequency = % of RS + % rs
= 32.5% RS + 32.5% rs
The frequency of each gamete is
RS ⇒ Parental ⇒ 32.5% (65% / 2) = 0.325rs ⇒ Parental ⇒ 32.5% (65% / 2) = 0.325Rs ⇒ Recombinant ⇒ 17.5% (35% / 2) = 0.175rS ⇒ Recombinant ⇒ 17.5% (35% / 2) = 0.175F1 Genotypes and Proportions
RS/RS = 0.325 x 0.325 = 0.1056 RS/Rs = 2x 0.325 x 0.175 = 0.1137RS/rS = 2x 0.325 x 0.175 =0.1137 rs/rs = 0.325 x 0.325 = 0.10562rs/RS = 2x 0.325 x 0.325 = 0.2112rs/Rs = 2x 0.325 x 0.175 = 0.1137rs/rS = 2x 0.325 x 0.175 = 0.1137Rs/rS = 2x 0.175 x 0.175 = 0.061Rs/Rs = 0.175 x 0.175 = 0.0306rS/rS = 0.175 x 0.175 = 0.0306F1 Phenotypes and Proportions
R-/S- = 0.1056 + 0.1137 + 0.1137 + 0.2112 + 0.061 = 0.6052 R-/ss = 0.1137 + 0.0306 = 0.1443rr/S- = 0.1137 + 0.0306 = 0.1443rr/ss = 0.1056
If R and S loci are 35 m.u. apart and a plant of genotype RS/rs is selfed, then the progeny phenotypes will be 0.606 RS; 0.106 rs; 0.144 Rs and 0.144 rS.
In this case, it is imperative to estimate gamete frequencies
RS = 0.65% / 2 = 0.325rs = 0.65% / 2 = 0.325Rs (recombinant) = 0.35 / 2 = 0.175rS (recombinant) = 0.35 / 2 = 0.175In consequence, the F1 genotypes will be RS/RS = 0.1056 (i.e., 0.325 x 0.325); RS/Rs = 0.1137; RS/rS = 0.1137; rs/rs = 0.10562; rs/RS = 0.2112; rs/Rs = 0.1137; rs/rS = 0.1137; Rs/rS = 0.06; Rs/Rs = 0.0306; and rS/rS = 0.0306.Finally, it is possible to obtain phenotypic frequencies by summing genotypic frequencies for each case in particular.In conclusion, if R and S loci are 35 m.u. apart and a plant of genotype RS/rs is selfed, then the progeny phenotypes will be 0.606 RS; 0.106 rs; 0.144 Rs and 0.144 rS.

A fruit fly of genotype B R/b r is testcrossed with b r/b r. In 84 percent of the meioses, there are no chiasmata between the linked genes; in 16 percent of the meioses, there is one chiasma between the genes. What proportion of the progeny will be B r/b r
Answer:
4 percent (4%)
Explanation:
A single crossover occurs between two (non-sister) chromatids belonging to homologous chromosomes. In this case, 16 percent of the meioses have a single crossover, thereby it will produce 8 percent of the chromosomes with the original (parental) combination in the progeny and the remaining 8 percent should be recombinants. From this result, it is reasonable to conclude that half of these recombinants should be 'Br' (and the other remaining 4 percent should be recombinants 'bR'), and therefore the answer is 4 percent (4%).

Scientists observed that the populations of top-level consumers in a particular ecosystem were rapidly decreasing. Further studies revealed that there was also a decline in producer productivity. Which other changes did the scientists most likely observe in the ecosystem?
increased producer diversity
decreased population size at all levels
decreased primary consumer populations only
increased primary and secondary consumer diversity
Answer:
The correct answer is - decreased population size at all levels.
Explanation:
A decrease in the productivity of producers of an ecosystem will lead to a decrease in all other organisms of the ecosystem including top-level consumers to the bottom-level producers due to the fact that producers provide energy and food to primary consumers.
It is because they are the only organisms that convert the sunlight to usable energy and food that transfer from one trophic level to other, so if the population of producers or their productivity will decrease then there will be decreased population size at all levels.

The diagram shows three steps in the carbon cycle.
The Carbon Cycle
Which two phrases best summarize the events taking place in Step 2?
A. Cellular respiration
B. Storing carbon dioxide in living organisms
C. Photosynthesis
D. Releasing carbon dioxide into the atmosphere
Answer:
A. Cellular respiration
C. Photosynthesis
Explanation:
There are two main processes occurs in the carbon cycle i.e. cellular respiration and photosynthesis. Plants absorb carbondioxide gas from the atmosphere through small openings called stomata. The carbondioxide enters the leaves and combine with water produces glucose and oxygen. Glucose is stored in different parts of plant whereas some oxygen is used by the plant and the remaining oxygen is releases in the atmosphere while on the other hand, in cellular respiration, glucose is broken down to produce energy in the form of ATP, carbondioxide gas and water.

Answer:
The correct answer is - c. an autoimmune process
Explanation:
Rheumatoid arthritis is a disease or condition that affects the joints mainly by swollen, and painful joints. It is an autoimmune disease as the person's own immune system attacks the body.
The presence of rheumatoid factor autoantibodies states that it is an autoimmune process. There are other autoantibodies also associated with this type of arthritis that are rheumatoid factors (RF), anti‐keratin antibodies (AKA), anti‐filaggrin antibodies (AFA), and anti‐perinuclear factor (APF).
