Which statement correctly distinguishes the difference in a glucose structure in one of the polysaccharides

Biology
1 answer:
Mariulka [41]2 years ago
6 0

Incomplete question. However, I provided some examples of polysaccharides and their varying glucose structures.

<u>Explanation:</u>

1. Glycogen and Starch: this polysaccharide has a glucose structure that consists of a hydroxyl (-OH) group which is attached to C_{1}.

2. Amylose: The glucose structure is joined together by 1,4 glycosidic bonds in a helix form.

3. Amylopectin:  In the glucose structure of Amylopectin it is observed that there are two types of bonding structure that exist, they are 1,4 and 1,6 glycosidic bonds.

Is the temperature profile in the thermosphere more like that of the troposphere or the stratosphere?
podryga [215]

The correct answer is: stratosphere.

This is because their temperatures are rising instead of decreasing.

There are 4 primary layers of the atmosphere on Earth:  

Troposphere (6-20km), the layer that we live in, where the weather occurs. Only nitrogen and oxygen present.

Stratosphere  (20-50 km), where the airplanes fly, contains the ozone layer, which absorbs harmful radiation from the sun.

Mesosphere (50-85 km), the coldest region of Earth’s atmosphere (-100 C), protective layer

Thermosphere (80-690), the hottest (1500 C) and the thickest layer which consists of the ionosphere and the exosphere.

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.

Based on the general trend of your data, what happened to the heart rate and pulse amplitude immediately after exercise and then
Nata [24]

Exercise is very vital to the body,it a form of physical activity.the sole aim of excercise is to maintain stamina, flexibility,keep fit and be overly healthy and well.

When we excercise, our heart rate increases and then it returns to the normal rate when with rest,when we take a break.there is reflection of vasoconstriction in the fingers as the blood is shunted to only the exercising muscles because it is noted that the pulse amplitude of the heart is always small after excercise and and increases slowly during recovery.

The amount of blood the heart pumps in a minute,that is the amount of blood ejected by the contraction of the left ventricle into systemic circulation increases when we are exercising and resistance to blood flow by skeletal muscles decreases.the blood vessels will try to adapt to the condition (exercise) inorder to control blood flow and as well meet energy demands.

When we finish exercising,our body temperature increases which will inturn cause increase in the pulse rate and the blood in our body makes way to our skin,hands and legs inorder to clear off the energy that was generated by the body(muscles) during exercise

Can we measure how old matter is?
zhenek [66]

Answer:

As of 2013, WMAP determined these parameters with an accuracy of better than than 1.5%. In turn, knowing the composition with this precision, we can estimate the age of the universe to about 0.4%: 13.77 ± 0.059 billion years!
