Specialized tissue on the wall between the atria. Electrical impulses pass from the pacemaker (SA node) through the _______ and the atrioventricular bundle (bundle of His) toward the ventricles.atrium (pl. atria)One of two upper chambers of the heart.capillary<span>Smallest blood vessel. Materials pass to and from the bloodstream through the thin walls. They have walls that are only one endothelial cell in thickness. This delicate, microscopic vessel carries nutrient-rich, oxygenated blood from the arteries and arterioles to the body cells. There, the nutrients are burned in the presence of oxygen (catabolism) to release energy.
At the same time, waste products such as carbon dioxide and water pass out of the cells and into these blood vessels. Waste-filled blood then flows back to the heart in small venues, which combine to form larger vessels called veins.</span>carbon dioxideGas (waste) released by body cells, transported via veins to the heart, and then to the lungs for exhalation.coronary arteriesBlood vessels that branch from the aorta and carry oxygen-rich blood to the heart muscle.deoxygenated bloodBlood that is oxygen-poor.diastole<span>Relaxation phase of the heartbeat.</span>

Which carbohydrate and example pair are not correctly matched? glucose - monosaccharide starch - polysaccharide sucrose - disacc
Taya2010 [7]
Carbohydrate is a group of compounds that is comprised of very simple units of sugar called the monosaccharide. From the prefix "mono", this means that the simplest unit is composed only of one block of sugar. Monosaccharide examples include: glucose, galactose, and fructose. From the given lists above, the one that does not match perfectly is the fourth pair. Glycogen is a multibranched polysaccharide. 

ANSWER: glycogen - monosaccharide

What evidence supports the LAW OF CONSERVATION OF ENERGY?
photoshop1234 [79]

Answer:

Taking into account photosynthesis, the evidence that best supports the law of energy conservation is energy is absorbed by chlorophyll and becomes chemical energy during photosynthesis (option 2).

Explanation:

Plants are autotrophic organisms, characterized by synthesizing their own nutrients by converting solar energy into chemical energy through photosynthesis.

During the process of photosynthesis, chloroplasts are capable of absorbing solar energy and converting it into glucose. This process involves the conversion of one type of energy into another.

With respect to the law of conservation of energy, it is necessary to consider:

  1. In the universe there is a constant amount of matter and energy, which is neither created nor destroyed, but transformed.
  2. Energy in an isolated system does not vary, unless it comes into contact with another system.
  3. The amount of energy that is absorbed and obtained is equivalent.

In photosynthesis, the chloroplast is not an isolated system, but has contact with the outside and is capable of absorbing the energy of the sun. This energy will be used to obtain a product, glucose, in an amount proportional to the amount of energy absorbed.

Regarding other options:

<em>     1. In photosynthesis, it is not </em><u><em>mechanical energy</em></u><em> that is transformed into chemical energy.</em>

<em>     3. </em><u><em>Oxygen is a product of photosynthesis</em></u><em>, during the process of chemical energy synthesis, from the combination of carbon dioxide, water and solar energy.</em>

<em>     4. It is true that the </em><u><em>sun gives off light energy that is absorbed by plants</em></u><em>, but it does not explain how this energy is transformed into chemical energy.</em>

Luden [163]

Answer:

The scaling exponent will be 0.75

Explanation:

According to a famous article by Max Kleiber*, the scaling of the metabolic rate or energy consumption for mammals Pmetab (measured in kcal/day) with the body mass Mb (measured in kilograms) is  P metab = 70 Mb^0.75 .

What is the scaling exponent (the quantity x in a scaling law A = cMbx) for the specific metabolic rate as a function of the animal’s body mass?

he scaling of the metabolic rate or energy consumption for mammals P=kcal/day

Mb=body mass in kilograms

Comparing

P metab = 70 Mb^0.75 .

with A = cMb^x

the scaling exponent will be 0.75

metabolic rate is the energy(in kilojoule) consumed at rest. it accounts for the highest amount of energy a body consumes daily

. How does temperature change with altitude in the troposphere?
olga55 [171]

The troposphere is hotter near the Earth's surface because heat from the Earth warms this air. As the altitude increases the number of air molecules decreases, the average of their kinetic energy decreases.

Does this help?

if it does please mark me brainliest! thanks:)
