In chickens, Black feathers (B) are dominant over white feathers (b). Complete the Punnett
Square for the following cross:
Mother: BB
Father: bb
What percentage of offspring will be Black?
What percentage of offspring will be White?
Answers
Answer:
(attached Punnett square below)
100% of the offspring will have black feathers
0% of the offspring will have white feathers
Explanation:
All the possible offspring have the genotype Bb, and since B (black) is dominant it will be the phenotype regardless of the presence of a b allele.
Therefore, all the offspring will be black (100%) and since none of the genotypes are bb there's no chance for white feathered chickens (0%)
hope this helps!

what develops as the dna molecule unzips with replication occurring on both strands at the same time
Answers
Answer:
The double-stranded parent DNA molecule gets separated and provides two template DNA strands for daughter strands synthesis. Enzyme DNA polymerase adds nucleotides complementary to template strands and synthesize daughter strands.
Explanation:
Answer:
The a cell divides, it is important that each daughter cell receives an identical copy of the DNA. This is accomplished by the process of DNA replication. The replication of DNA occurs during the synthesis phase, or S phase, of the cell cycle, before the cell enters mitosis or meiosis.

Describe the following natural disasters:
• Hurricanes:
• Tornadoes:
• Earthquakes:
• Floods:
• Wildfires:
Answers
Answer:
Hurricanes are large, swirling storms. They produce winds of 119 kilometers per hour (74 mph) or higher. That's faster than a cheetah, the fastest animal on land. Winds from a hurricane can damage buildings and trees.
tornado is a violent rotating column of air extending from a thunderstorm to the ground. The most violent tornadoes are capable of tremendous destruction with wind speeds of up to 300 mph. They can destroy large buildings, uproot trees and hurl vehicles hundreds of yards. They can also drive straw into trees.
Earthquake is a term used to describe both sudden slip on a fault, and the resulting ground shaking and radiated seismic energy caused by the slip, or by volcanic or magmatic activity, or other sudden stress changes in the earth.
A flood is an overflow of water that submerges land that is usually dry. In the sense of "flowing water", the word may also be applied to the inflow of the tide. Floods are an area of study of the discipline hydrology and are of significant concern in agriculture, civil engineering and public health.
Wildfires are fires that burn out of control in a natural area, like a forest, grassland, or prairie. They often begin unnoticed. They spread quickly, and can damage natural resources, destroy homes, and threaten the safety of the public and firefighters. Humans cause most wildfires.
Hurricanes: Hurricanes form when warm air over the water rises, it is replaced with cool air, if there is enough warm water storm clouds and wind speed can grow and cause the hurricane.
Tornadoes: Tornadoes form when warm air collides with cold air.
Earthquakes: a sudden and violent shaking of the ground, sometimes causing great destruction, as a result of movements within the earth's crust or volcanic action.
Floods: an overflowing of a large amount of water beyond its normal confines, especially over what is normally dry land.
Wildfires: A wildfire, bushfire, wildland fire or rural fire is an unplanned, unwanted, uncontrolled fire in an area of combustible vegetation starting in rural areas and urban areas

A. Photosynthesis releases energy and cellular respiration stores energy.
B. Photosynthesis releases carbon dioxide and cellular respiration releases oxygen.
C. Photosynthesis removes oxygen from the atmosphere and cellular respiration replaces it.
D. Photosynthesis removes carbon dioxide from the atmosphere and cellular respiration replaces it.
???
Answers
Photosynthesis and respiration depend on each other and complement themselves. Option D. Photosynthesis removes carbon dioxide from the atmosphere and cellular respiration replaces it.
Why are Photosynthesis and respiration complementary processes?Photosynthesis occurs in chloroplasts, while respiration occurs in mitochondria.The photosynthetic process needs solar radiation to produce organic compounds, while the respiration process needs the organic compounds to obtain chemical energy.Photosynthesis transforms CO₂ into organic compounds, while respiration transforms organic compounds into CO₂.In the process of photosynthesis, it occurs a release of oxygen, which is then used during the respiration process. Both processes produce energy, which will be used in other cellular reactions.Respiration´s final products are CO₂, ATP, and waterPhotosynthesis´s final products are carbohydrates and oxygen.
The correct option is D. Photosynthesis removes carbon dioxide from the atmosphere and cellular respiration replaces it.

what would happen it the palisade mesophyll were below the spongy mesophyll
Answers
Answer:
Photosynthesis will be affected or may not occur.
Explanation:
This is because palisade mesophyll are packed cells and have cylindrical shape with chloroplasts. Chloroplast are present here which control chlorophyll and this area specialises in absorbing light energy from the sun efficiently. If it is below spongy mesophyll, it's ability to absorb light energy is affected as there is an hindrance layer, and when chlorophyll couldn't absorb light energy, photosynthesis cannot occur.

Glucose provides energy for cells. Different cells have different mechanisms for glucose intake. Intestinal cells contain proteins that transport glucose against its concentration gradient. These proteins couple the movement of glucose to the movement of sodium down its concentration gradient. Red blood cells have transporter proteins embedded in their membranes. When bound by a glucose molecule, these proteins change shape and allow glucose to move down its concentration gradient into the cell.
Based on this information, what type of transport is used for glucose in blood and intestinal cells?

There is a dominant trait that affects the short arm of chromosome #4 known as Huntington's disease. A woman that is heterozygous for Huntington's disease and a normal, unaffected male have a female child. What is the probability that this child may be affected by the disease?
Answers
Answer: 50%
Because there are different systems in the body to prevent diseases, however chromosome diseases are usually hereditary so there is about a 50% chance that the child may be affected by this disease.
Huntington's disease is a dominant chromosomal disorder, when a woman who is heterozygous marries a man who is normal, then the probability for the child to be affected is 50%.
What is Huntington's disease?Huntington's disease is a rare genetic disease which causes the progressive breakdown of neurons present in the brain. Huntington's disease has a wide impact on a person's functional abilities and results in movement, cognitive thinking and psychiatric disorders.
When a woman who is heterozygous (Hh) for Huntington's disease marries a man who is normal (hh) for the disease, the probability of the offspring to be affected with the disease can be calculated with the help of Punnett square. And, it will be 50%.

Transcription is A. The process of making RNA from DNA. B. The activation of a gene that produces proteins. C. Irreversible changes to the DNA sequence. D. The process of making proteins from RNA
Answers
Answer: A. The process of making RNA from DNA.
Explanation:
The transcription can be defined as the process of transfer of genetic information from DNA or deoxyribonucleic acid into messenger RNA. For this double strands of DNA are separated and each strand act as a template strand for the synthesis of mRNA. The transcriptions is initiated by the enzyme RNA polymerase. The enzyme RNA polymerase utilizes DNA for synthesizing the matching complementary bases. The mRNA molecule get elongated and serves as a blueprint for the synthesis of protein in translation.
