Mammals. I am no scientist, but I think that they are closer to mammals due to the fact that they are warm-blooded, and they raise their young. Reptiles are cold blooded and usually leave their offspring to fend for themselves.
Answer:
<em>Alfred Wegner</em> proposed the theory of <em>Continental drift</em> which suggested the continents move and started out in different positions from what they are currently. In the 1960s, scientists discovered the spreading apart of <em>the seafloor</em>. This in turn led to the theory of <em>Plate tectonics.</em> This theory says that the <em>earth's outer crust, the lithosphere</em> is made of plates which float on a "plasticlike" undersurface called the asthenosphere. Where these plates come together at their<em> boundaries</em>, changes take place in the crust and its feature.
Explanation:
Alfred Wegner proposed the theory of Continental drift which suggested the continents all continents were once connected in a large single mass that broke apart around 200 million years ago before slowly moving apart to where they are currently.
In the 1960s, Harry Hess, a geologist and Navy submarine commander during World War II, discovered the spreading apart of the seafloor. This in turn led to the theory of Plate tectonics. This theory says that the earth's outer crust, the lithosphere is made of plates which float on a "plasticlike" undersurface called the asthenosphere. Where these plates come together at their boundaries, changes take place in the crust and its feature.
Answer:
Option D (4), add phosphate groups
Explanation:
Kinase enzymes are responsible for cellular activation. Protein kinase causes phosphorylation of specific amino acids by utilizing ATP as source of phosphate.
It adds phosphate groups (PO43−) and induces biological activity of biomolecules (such as proteins, lipids, and nucleic acids) by changing their conformation thereby activating them .
Human genome consists of several hundreds of kinase encoding genes which are involved in multiple phosphorylation reactions with in the cytoplasm of cells.
Hence, Option D (4) is correct
The stages of meiosis PMAT prophase Metaphase anaphase telaphase
Answer:
The correct answer is "open".
Explanation:
The fifth wheel is an element that couples a heavy-duty pickup truck and a camping trailer. To unlock the fifth wheel it is necessary to pull the release handle to the open position. In the open position of the release handle the fifth wheel is unlocked, which allows to uncouple the heavy-duty pickup truck and the camping trailer
