Some bacterial cells live in very cold environments (such as the arctic ocean), but they still require membrane fluidity like th

eir cousins from more tropical climates. How would the membrane structure of a bacterial cell from a cold climate be different from the membrane structure of a bacterial cell from a very warm climate? Choose one:

3 0

Answer and explanation;

-Arctic microbes would have membranes with more unsaturated fatty acids; increasing the unsaturated fatty acid ratio would make it harder for the fatty acids to pack together. This will keep the membrane fluid at lower temperatures, which will benefit organisms that live in very cold climates.

-Microorganisms are adapted for optimum functioning in their normal physiological environments. Any extreme change in environmental conditions from the optimum inflicts a stress on an organism. For this reason they must accommodate a variety of changing conditions and stresses in their environment in order to survive and multiply.

Superficial region around the renal medulla
nalin [4]

Answer:

Renal cortex

Explanation:

The renal medulla of a kidney is surrounded by renal cortex. The renal cortex is the granulated layer. It is the renal cortex in which the renal corpuscle (glomerulus and Bowman's capsule) are present. The renal cortex is reddish brown in color. This is due to the fact that most of the renal arteries deliver the blood to the cortex.

Muscles whose fibers run at an angle to the long axis of the body are called __________.
lyudmila [28]
The answer to this question would be: oblique muscle

Oblique muscle runs at the long axis of the body. There are a few oblique muscles in human such as the external/internal abdominal oblique muscle in the belly that makes the "six-pack" looks. Other would be superior/inferior oblique muscle in the eye that moves the eyeball.

Excitatory postsynaptic potentials (EPSPs) produced nearly simultaneously by different synapses on the same postsynaptic neuron
lakkis [162]

Answer: summation

Explanation:

The process which determine if an action potential will be generated or not depends on the combined effects of the signal inputs from multiple sources of  synapse or from the repeated signals from the same synapse.  

If the input signals reach the threshold voltage, action potential will be generated. (all –or –none principle).Therefore, this  process is a determinant of  the likelihood of action potential generation  and it is called summation.

Summation is the ability to integrate multiple PSPs at multiple synapses.it is  the process that determine if an action potential will be generated by combined effects of inhibitory or excitatory  signals.

Based on the pathways and voulme of applied stimuli in the presynaptic neuron;

The signals can be temporal summation ( consecutive  signals  produced from the same  synapse)where action potential of high frequency in the PSN generated action potential in the post synaptic neuron, which summate with one another. Or Spatial where signals inputs are from multiple presynaptic cells.

For which of the following is the velocity constant (speed/direction does not change)? Question 5 options:
irina [24]
Running up a tree after running straight is a change in direction thus, although the speed is same 30mph, the velocity is different. Now, in choice B, the cat is slowing down after having escaped from the dog. This is also a change in velocity (because the speed decreases).When the cat is sitting still the whole time, its velocity is 0.0mph the entire time. That means the velocity doesn't change <span>And when the cat is running around the house, the cat is changing direction (thus velocity is different). (This is relevantly a circular motion, and acceleration is a non-zero constant, and thus veloicty of course isn't same).</span>
