Answer:

Membrane protein is made up of phospholipid bilayer.

Explanation:

Membrane proteins have one or more segments that are embedded in the phospholipid bilayer. This structure helps cells to maintain their shape, carry out changes triggered by chemical messengers, and transport material. Cell membrane have thousands of proteins that are embedded in the cell's lipid bilayer. The proteins present in the cell membrane is responsible for the active transport means use energy to transport molecules and ions across the cell membrane.

Answer:

Hi, there the answer is

C.It is a frameshift mutation that changes many amino acids.

Explanation:

Due to the triplet nature of gene expression by codons, the insertion of the single Adenine nucleotide will disrupt the reading frame of the gene (frameshift mutation), such that it is no longer evenly divisible by three.

Thus, resulting in a completely different translated protein from the original.

Hope this helps :)

Answer: maritime tropical air mass

Explanation: The oceanic tropical air mass regularly creates a warm, muggy climate in the mid-year. The air mass begins from over the warm water of the jungles and Gulf of Mexico, where warmth and dampness ordinarily move to the air above from the water beneath.

Answer:

1 , 11 and 111 are correct

Answer:

Archosauria (the "ruling reptiles") is a major group of diapsids, differentiated from the other diapsids by the presence of single openings in each side of the skull, in front of the eyes (antorbital fenestrae), among other characteristics. This continues the tetrapod trend of the reduction of skull bones by the fusion of multiple bones and the opening of fenestrae in the skull. This helps to lighten the skull, provides more room for muscles and other tissues, and allows more skull flexibility (kinesis) when eating. Other typical archosaurian characteristics include another opening in the lower jaw (the mandibular fenestra), a high narrow skull with a pointed snout, teeth set in sockets (called thecodont tooth implantation), and a modified ankle joint.

Diapsids ("two arches") are a group of amniote tetrapods that developed two holes (temporal fenestra) in each side of their skulls about 300 million years ago during the late Carboniferous period.[1] The diapsids are extremely diverse, and include all crocodilians, lizards, snakes, tuatara, turtles, and birds.[2] Although some diapsids have lost either one hole (lizards), or both holes (snakes and turtles), or have a heavily restructured skull (modern birds), they are still classified as diapsids based on their ancestry. At least 7,925 species of diapsid reptiles[3] exist in environments around the world today (nearly 18,000 when birds are included).

Reptilia, presented as a Class in our classification, includes turtles (Testudines), snakes and lizards (Lepidosauria), crocodiles and their relatives (Crocodilia), and birds (Aves), as well as a number of extinct groups.

Answer:

Hypertonic solution

Explanation:

Hypertonic solution refer to the solution of a cell if the solute concentration is higher inside than outside and it cannot cross the membrane. In Hypertonic solution, Water crosses the cell membrane in both directions which result in more b water leaving the cell than entering it. Therefore, a cell place in this solution will shrink due to exosmosis.

Answer:

Mammal 2 and 4 are most related, why?

Explanation: They have TCT, CAG, CTG and CA, the only ones it doesn't have is the last ones, A and G, making it the only difference. 1 has 2 differences to 2, 3 differences to 4, and 3 has 2 differences as well, therefore 2 and 4 have the least differences.

Answer:

2 and 4

Explanation:

You can see their patterns match except for the last letters of 2 and 4

Answer:

Within a population, each individual mutation is extremely rare when it first occurs; often there is just one copy of it in the gene pool of an entire species. But huge numbers of mutations may occur every generation in the species as a whole.
