rodikova [14]3 years ago

Answer:

Both numbers are equally important and you need both. There are two because you need both.

Explanation:

When you go to take your blood pressure the top number is the systolic pressure and it measures the amount of pressure in your arteries during the contraction of your heart muscle. The bottom number is called the dialostic pressure and measures the amount of blood pressure of you heart muscle between beats. Healthy blood pressures numbers are 120 over 80, or 120/80.

According to the _____ theory, when a physiological need, such as hunger, creates an aroused tension state, it drives the organi
madreJ [45]

Answer:

the drive-reduction theory

Explanation:

The drive-reduction theory is one of the theories of motivation.

This theory contains the idea that a physiological need creates a drive, which in turn motivates an organism to satisy their need.

The theory targets homeostasis or biological balance.

When there is a need such as lack of water, the need would cause a drive to be developed (thirst).

The drive would activate a response (search for water to drink).

The response is then terminated when the need has been satisfied.

a. What do the letters R and I represent ? b. What is the genotype of the pink-flowered snapdragons? c. Explain whether the alle
-Dominant- [34]

Answer:

a) R= allele for red colored flower

I= Allele for ivory flowers

b) Genotype of pink flowered plant: RI

c) Incomplete dominance

d) 100%

Explanation:

When the dominant allele is not able to fully mask the expression of the recessive allele in the heterozygous state, it is said to be incomplete dominance. The R and I alleles impart red and ivory color respectively to the flowers of the snapdragon plant. The heterozygous genotype "RI" imparts a pink color to the flowers and therefore, the alleles are said to exhibit incomplete dominance.

The genotype of red-flowered snapdragon plant = RR. The genotype of ivory flowered snapdragon plant= II. When a red-flowered snapdragon plant is crossed with an ivory flowered snapdragon plant, the progeny is heterozygous in nature with the "RI" genotype. The phenotype of the progeny is "Pink flower" since the R allele is incompletely dominant over the allele I.
