The intrinsic rate of the atrioventricular av bundle is 40 to 60 beats per minute (bpm).
<h3>
What is the Atrioventricular (AV) and the intrinsic rate?</h3>
Atrioventricular (AV) can be regarded as the block that usually altered the interruption of impulse transmission between the atria to the ventricles.
And this have the 40 to 60 beats per minute (bpm) as the intrinsic rate.

It would be a heterotroph and a omnivore because it eats grains and meats and a heterotroph because it has to get food.
1) To calculate the population density you first need to know how many <span>squirrels form that population.
To calculate the number of</span><span> squirrels:
1500</span> squirrels is the capacity, so it's equivalent to 100%
So how much squirrels are present in 80% of the area:
1500----100 %
x----------80 %
x= 1200 <span>squirrels
</span>
2)Population Density equals the number of squirrels divided by the land area
In the first part was calculated the number of squirrels and the exercise gives us the area in hectares so the only thing left to do is divide them.
(since this exercise doesn't specify that the area needs to be in a certain measurement we can use hectares)
Population Density = 1200/ 150
<span>The population density of the squirrels is 8 per hectare</span>
Answer:
Each species has a specific identifying number of chromosomes. For example, a cat, <em>Felis catus</em>, has 38 chromosomes, while corn, <em>Zea mays</em>, has 20 chromosomes each chromosome carries specific genes that are unique to that chromosome.
Explanation:
Chromosomes vary in shape and number among living beings. For example, the bacterial chromosome is a unique circular molecule, while human beings have 46 lineal chromosomes arranged in pairs (23 pairs). The total number of chromosomes is specific to each species, and it is denoted as the "chromosomic dotation" of the species.
Genes are the hereditable units that transmit the information needed to specify traits, from parents to offspring, generation to generation. Genes are arranged in sequence in the chromosomes. A chromosome might contain hundreds of thousands of genes.
Genes vary in size and shape. They are composed of pairs of bases, and these sequences also vary in number, producing genes of different lengths. In general, genes code for proteins. Proteins create the organism tissues and perform or carry out specific functions in the organisms, controlling almost all processes and chemical reactions.
Each chromosome carries <u>specific</u> genes that code for <u>specific </u>proteins that have <u>specific</u> functions in the organisms. Each chromosome carries information to synthesize different proteins needed to accomplish a certain function. But <u>not all chromosomes carry the same gene sequences</u>. Only homologous chromosomes carry information for the same trait, but even this information is not necessarily the same. They might have the same gene but different alleles.
