Sickle-shaped red blood cells result from a mutation in the gene that codes for hemoglobin.
This mutation results in sickle-cell anemia. A partial sequence of bases from a normal
hemoglobin gene and a sequence that results in sickle-cell anemia are shown below.
Normal hemoglobin:
T-G-A-G-G-T-C-T-C-C-T-C
Sickle-cell hemoglobin: T-G-A-G-G-T-C-A-C-C-T-C
What type of mutation is depicted in this sequence?
A Substitution
B Insertion
C Deletion
D Frameshift
Option A
Option B
Option C
Option D

Answer 1

Answer:

Substitution

Explanation:

Substitution is when is a mutation that exchanges one base for another. In this case, the T is an A.

D. overfishing is changing the structure of ecosystems, haring the plankton that regulate the pH of ocean water.
E. acid rain has worsened over the last two decades.

Answers

Answer: b

Explanation:

Its b because Ocean acidification is occurring because excess carbon dioxide (CO2) in the atmosphere is being absorbed at the surface of the ocean at an increasing rate. This excess CO2 results in more hydrogen ions, which increases the acidity of the ocean.

B. The ocean absorb about25%of the carbon dioxide emitted into the atmosphere by human activities

Answer:

So they are more careful

Answer:

Renewable energy

Explanation:

Renewable energy, on the other hand, typically emits less CO2 than fossil fuels. In fact, renewables like solar and wind power—apart from construction and maintenance—don't emit any CO2 at all. With renewable energy, you can breathe easier, stay cooler, and create a more comfortable world for generations to come.Jan 2, 2018

¿Cómo podemos autorregular la temperatura en las plantas, sin importar que el ambiente esté frío o caluroso?.

Answers

Answer:

Las plantas regulan la temperatura por sí mismas.

Explicación:

No podemos autorregular la temperatura en las plantas, pero las plantas regulan la temperatura por sí mismas. Cuando la temperatura del cuerpo de la planta aumenta, se pueden regular mediante la transpiración. La transpiración es la evaporación del agua desde el interior del cuerpo a través de los estomas, al igual que el sudor en los seres humanos. Con esta liberación de humedad, el calor también se elimina y enfría la temperatura corporal.

after fertilization a single cell divides successfully to form a multicellular structure what happens next in order for this structure to develop tissues and organs to meet the needs of the organism

Answers

Answer:

After fertilization, a single cell divides successfully to form a multicellular structure. What happens next in order for this structure to develop tissues and organs to meet the needs of the organism? The cells undergo differentiation into particular body parts.

A multicellular organism develops from a single cell (the zygote) into a collection of many different cell types, organized into tissues and organs. Development involves cell division, body axis formation, tissue and organ development, and cell differentiation (gaining a final cell type identity).

She sniffled and used a handkerchief to wipe away her tears. Taking a deep breath, she rapped on the door of the world's most famous detective.Mrs. Hudson answered the door and ushered the visitor to Sherlock Holmes' flat. The detective stood tall and confident, gazing at Mrs. Blakely with an inquisitive smile. He invited Mrs. Blakely to enter. Mrs. Hudson offered her some tea. After using the tea to warm her hands, Mrs. Blakely felt capable of explaining her situation. Yesterday afternoon, Mrs. Blakely had arrived home to find a masked individual robbing her house. When the mysterious figure heard her approach, he or she ran farther into the house and disappeared. All that remained was the black mask lying on the ground. Mrs. Blakely's most prized possession, a massive purple gem, also had disappeared. While Mrs. Blakely knew it would be useless to ask Holmes to retrieve the gem, she wanted him to determine how the thief and gem had disappeared so completely.Sherlock Holmes listened to the tale and agreed to visit the crime scene. The safe was open and empty, but it was not damaged. There was no visible entry into the room where the safe was kept: the windows were sealed, and the door was not damaged. Mrs. Blakely led Sherlock Holmes farther into the house and stopped in the middle of a hallway of old portraits. There were no windows, and the only door was at the other end of the hallway."This spot is where I found the black mask," Mrs. Blakely explained.Sherlock Holmes inspected the hallway with a wrinkled brow. He walked up and down the hallway. He put his hand on the smooth floor. Then, Sherlock's brow smoothed and a glint entered his eyes. Turning to the wall, he pressed the expensive portrait into the wall."What are you doing to my painting?" Mrs. Blakely gasped."Calm down, Mrs. Blakely," Holmes replied. "The solution to this mystery is staring you in the face. There is no sign of a break in, so the thief has access to the house. The thief disappeared in this spot without using the far door, so there must be a hiding spot within the walls or floor. There are scratches on the ground near this portrait. I felt a draft when I reached down to test the floor. It's elementary, Mrs. Blakely. The thief is hidden in the wall behind this portrait."Holmes pushed the portrait harder into the wall. The wall moved, revealing a hiding place. Sherlock Holmes lit a candle. Its light revealed a sleeping maid with a gigantic purple gem clasped in her hands. The mystery of the disappearing thief was solved.Select the detail that supports this statement: Mrs. Blakely was upset when she arrived to speak with Sherlock Holmes.
