3. Briefly summarize in your own words what alternative explanations have been proposed for melanism that do not have to do with bird predation.
Answer & explanation:
Melanism occurs due to a genetic mutation that causes the excessive and concentrated production of the black pigment, called melanin. The consequence is living beings with darkened skin or fur. There are three types of melanism.
Adaptive melanism occurs by the need to adapt to the environment, a condition that will be passed through the generations. This melanism allows animals to camouflage themselves during hunting or to hide from predators.
Industrial melanism is related to human interference, especially industrial activities, in the lives of animals (dark-colored moths are the best-known cases). Air contamination is one of the main factors for this condition.
There is also pseudo-melanism, which partially affects animals and is generally motivated by genetic mutations. In certain species, the characteristic spots and stripes appear larger and darker than usual. This type of melanism is very present in cats such as tigers, cheetahs, leopards. However, other animals can still be affected.
how does density affect refraction?
Answer:
Density of any substance or medium determine the amount of light that will be refracted.
Explanation:
Density of any substance or medium determine the amount of light that will be refracted.
The higher is the density of any medium, the higher will be the number of atom or molecules in a given medium and hence more obstruction will be produced for light. High density also causes high refractive index.
The light usually bends away from the normal when light travels from a region of low to high density and light bends towards the normal when light travels from a region of high to low density
Which of the following examples of membrane transport requires energy from ATP?
a. Movement of Nations from a lower concentration inside the cell to a higher concentration outside of the cell
b. Movement of glucose molecules from a higher concentration outside of the cell to a lower concentration inside of the cell
c. Movement of water into a cell
d. None of the above
Answer:
Active transport uses energy to transport molecules across the plasma membrane. This uses energy from ATP. They also use pumps to get molecules in or out of the cell. Passive Transport does NOT use energy to transport molecules across the membrane.

Explain the relationship between coral and algae, and how a problem with algae photosynthesis caused coral bleaching in the Great Barrier Reef.
The relationship between Coral and Algae and how a problem with Algae photosynthesis caused Coral bleaching in the Great Barrier Reef happens in a way that when Coral reefs become stressed as a result of changes in condition such as the temperature, lights or nutrients,These Coral beef therefore expel the symbiotic algae living in there tissue which they have feeding relationship with, the expulsion of those algae will make them to turn to white completely.
However,warmer water temperatures can give rise to Coral bleaching.
The relationship between coral and algae is mutualism.
There is a mutualistic relationship between corals and algae because both coral and algae provides benefits to each other. The coral provides a protected habitat and raw materials which the algae need for photosynthesis. whereas the algae produce oxygen and remove waste materials from coral.
A problem with algae in the process of photosynthesis caused coral bleaching because warm water restrict algae from photosynthesis which leads to the death of algae which results in the coral bleaching in the Great Barrier Reef so we can conclude that the relationship between coral and algae is mutualism.

The amino acids in the original partial sequence (N-term-...P-I-E...-C-term) have little to no impact on protein structure and function. However the amino acid sequence near the C-terminal end of the protein is required for normal function. Any amino acid changes in this region of the protein will result in a nonfunctional protein. Given this information, which reversion mutation in the gene would restore the normal function of the protein?
a. Insertion of 2 base-pairs in the region of the proline codon
b. Deletion of 5 base-pairs in the region of the proline codon
c. Deletion of 2 base-pairs in the region of the proline codon
d. Deletion of 1 base-pair in the region of the proline codon
e. Insertion of 1 base-pair in the region of the proline codon
f. Insertion of 4 base-pairs in the region of the proline codon
Answer:
OPTIONS : B,C,E,F
Explanation:
The Reversion mutation in the gene that would restore the normal function of the protein :
All the options given can restore the normal function except options : A and D
For Deletion of 5 base-pairs in the region of the proline codon
Normal sequence 5' - G | CCG | AUC | GAA | CU - 3' while the mutated sequence is : 5' - G | CCG | AUG | AAC | U - 3' . this shows that the removal of the 5 case pairs will only remove 2 amino acids restoring the normal protein in the process and not affect the C terminal of the amino acids and also the reading frame will be restored
normal protein.
For Deletion of 2 base-pairs in the region of the proline codon
The Normal sequence 5' - G | CCG | AUC | GAA | CU - 3' while Mutated sequence 5' - G | CCG | AUG | AAC | U - 3'
This shows that the deleted base pair is from this codon hence removing the two base pairs will lead to the reading frame been restored and also the C terminal amino acids, but this will result to a protein with a less than one amino acid

Annette's maternal grandfather died of Huntington's disease when he was 53 and Annette was 8. Huntington's is a rare autosomal dominant degenerative neural disorder that usually hits people in their late forties, early fifties. Annette loved her grandfather very much and was deeply affected by the painful progression of his disease. She wants to get pregnant but does not want to risk giving birth to a child that will suffer as much as her grandfather. If she tested positive for Huntington's, what is the probability of her first child to develop Huntington's? Of her second child? Of her mother? (Note that since Huntington’s is so rare, you can assume that neither grandmother, nor father or partner have the Huntington’s mutation).
Answer and Explanation:
Huntington disease is caused by a mutation in the gene that codifies for the Huntingtin protein (Htt). The mutation produces an altered form of the protein leading to the neuron´s death in certain areas of the brain.
Huntington disease characterizes for being,
• Hereditary, passing from generation to generation. To express the disease, a person must have been born with an altered gene.
• Autosomal, affecting men and women equally, because the mutated gene is located on an autosomal chromosome.
• Dominant, which means that by getting only one copy of the altered gene coming from any of the parents, the receiving person will express the disease. The mutation in the gene dominates over the normal gene copy.
• Expressed by heterozygosis. Most people affected by the disease are heterozygous, with a normal copy and a mutated copy.
An affected heterozygous person has 50% of chances to give a normal recessive allele or an altered dominant allele. When one of the progenitors is a carrier and the other one is a healthy person, the progeny have 50% of probabilities of inheriting a dominant allele expressing the HD from the affected parent.
In the exposed example, Annette probably is heterozygous, Hh, and she marries a healthy man, hh.
Parental) Hh x hh
Gametes) H, h h, h
F1) 1/2 Hh, 1/2 hh
The probability of the first child to develop HD is 50%, or 1/2
The probability of the second child to develop HD is also 50%
The probability of both children to develop HD is 1/2 x 1/2 = 1/4, or 0.25
Now, Annette´s grandpa had the disease, Hh
Annette´s grandma did not, hh
The probability of her mother to develop HD is 50% because she could just inherit the dominant allele from her father.
Identify EITHER one nitrogen compound OR one phosphorus compound that is considered a pollutant when released by human activity into the environment. For the compound you identified, describe the human activity and a specific environmental problem that results.
Answer:
Sodium tripolyphosphate (STPP)
Explanation:
Sodium tripolyphosphate (STPP) is a compound of phosphorus that is used to manufacture detergent.
This chemical is released into the environment when detergents are used to wash dishes or in laundry.
This compound finds its way into water bodies and leads to overgrowth of algae. This is known as eutrophication.
As these algae die, decomposition of the organisms lead to a drop in oxygen level of water bodies and increase in biochemical oxygen demand. As a result of these, some aquatic species may begin to die or relocate to other water bodies.

Which part of the plant and animal cells in the animals does cellular respiration take place
cellular respiration in eukaryotic cells takes place in the mitochondria. Both animal cells and plant cells depend on cellular respiration for their energy needs, because both animal cells and plant cells need ATP.
The first energy-generating steps in glycolysis begin when glyceraldehyde 3-phosphate undergoes an energetically favorable reaction in which it is simultaneously oxidized and phosphorylated by the enzyme glyceraldehyde 3-phosphate dehydrogenase to form 1,3-bisphosphoglycerate, with the accompanying conversion of NAD+ to NADH. In a second energetically favorable reaction catalyzed by a second enzyme, the 1,3-bisphosphoglycerate is then converted to 3-phosphoglycerate, with the accompanying conversion of ADP to ATP. Which of the following statements is TRUE about this reaction?
a. The cysteine side chain on the enzyme is oxidized by NAD+.
b. The energy stored in the phosphate bond of glyceraldehyde 3-phosphate contributes to driving the reaction forward.
c. The ΔG° for the oxidation of the aldehyde group on glyceraldehyde 3-phosphate to form a carboxylic acid is more negative than the ΔG° for ATP hydrolysis.
d. The reaction glyceraldehyde 3-phosphate---->1,3-bisphosphoglycerate should be inhibited when levels of NADH fall.
Answer:
The answer is option B.
Explanation:
It is stated that "the enzyme glyceraldehyde 3-phosphate dehydrogenase to form 1,3-bisphosphoglycerate" which indicates that the energy from the broken bonds of the glyceraldehyde 3-phosphate provides energy for the reaction to take place.
So the correct answer is option B.

Why is cell division important after fertilization?
Answer:
Perhaps most importantly, without cell division, no species would be able to reproduce—life would simply end (or would have ended a long time ago). Every human, as well as every sexually reproducing organism, begins life as a fertilized egg (embryo) or zygote.
Cell division is important after fertilization because it is necessary for growth and multiplication.
CELL DIVISION:
Cell division is the process by which a single cell is duplicated to produce more copies of itself. Fertilization is the process that joins a sperm and egg cell together in sexual reproduction to form the zygote. However, the diploid (2n) zygote needs to grow and multiply. Hence, the zygote formed as a result of fertilization undergoes a form of cell division called mitosis. Therefore, cell division is important after fertilization because it is necessary for growth and multiplication.Learn more at: https://brainly.com/question/3327479?referrer=searchResults
