Nervous tissue is found in the brain, spinal cord, and nerves. It is responsible for coordinating and controlling many body activities. It stimulates muscle contraction, creates an awareness of the environment, and plays a major role in emotions, memory, and reasoning.
<span>The answer is molecular clocks.
Molecular clocks use rates of mutation to measure evolutionary time. This technique is based on the fact that mutations add up at a fairly constant rate in the DNA of species that evolved from a common ancestor. The more mutations that happened in each lineage, the greater is the differences between these lineages and vice versa.</span>
Two chromosomes in a pair – normally one inherited from the mother and one from the father. For example, the two copies of Chromosome 1 in a cell would be referred to as homologous chromosomes.
Explanation:
El flujo sanguíneo en el lecho capilar es el 5% del gasto cardíaco y depende estrechamente del resto de los vasos que integran la microcirculación. La estructura de los capilares varía de órgano a órgano, pero típicamente están formados por una capa única de células endoteliales apoyadas sobre una membrana basal.
Answer:
100%
Explanation:
Let’s represent the dominant tongue rolling trait as: R
and the recessive trait as: r
A homozygous individual will have the same alleles i.e. RR (for dominant), rr (for recessive). Note that Rr is heterozygous.
An individual homozygous dominant for tongue rolling has the alleles RR
and an individual who cannot roll his tongue has rr, that is homozygous recessive
.
To determine the trait of their offspring, we'll cross their traits
Crossing the two
:
RR x rr
Rr, Rr, Rr, Rr
All the offspring will inherit the dominant R and the recessive r from both parents.
Therefore, there is a 100% chance that the child will have a heterozygous genotype.
