WILL GIVE BRAINLIEST / Dora was asked to label the upwelling and downwelling locations on this map of the earth. Dora labeled A as an area of downwelling. Which one of the following reasons does NOT support her answer? 1 A is near the south pole and downwellings are usually near the poles.

2 The cold, salty water forming at point A has a higher density than the warm water and will need to sink.

3 A has warm surface water coming in and a cold water current going out.

4 A is near the equator and downwellings are usually near the equator.

With the description of the different cell walls, membranes, and associated proteins set in the students' minds, you now need to introduce them to the idea that the cell wall can also act as a foundation to build things upon. bacterial appendages require a strong foundation that will offer the support needed to move and function in a dynamic world. for example, flagella are long, whiplike protein structures that are used by many gram-positive and gram-negative bacteria for locomotion. in order to function effectively, a flagellum must be firmly anchored to the cell wall. how will you be able to get across the idea that the peptidoglycan cell wall is strong enough to support such a mechanism? with a protein rod that passes through the cell wall and protein rings used to anchor it in the membranes, these basal bodies are the rudimentary biological motors that use atp power to spin the hook and the flagella attached to it. bacterial flagella have a biological motor that spins within the cell wall and is powered by atp. this allows the flagella to spin in a whiplike motion to propel the bacterium.

How does the study of genetic disorders such as pku biologists understand normal alleles?

The mammal pictured below is a silvery mole rat. which statement is an inference based on the picture? the animal is ugly. the animal has hairless feet with sharp claws. the animal has prominent upper and lower incisor teeth. the animal likely has poor vision since its eyes are so small.
