Answer:

Many flowers produce nectar, a sugary liquid that many insects eat.

Explanation:

When an insect lands on a flower to feed, pollen grains stick to its body. As the insect moves to another flower of the same species, these pollen grains are transferred to the flower's stigma and pollination occurs. It can help even more plants grow.

An electrocardiogram (ECG) provides information about ________. A. the pressure of blood in the heart chambers B. the rhythm of
mario62 [17]

An electrocardiogram (ECG) provides information about B) the rhythm of heart contractions

The rhythm of heart contractions can be known by an electrocardiogram (ECG).

An ECG or Electrocardiogram is a method to diagnose the heart conditions to check the normal functioning of the heart.

The process to measure the electrical signals of the heart can be done by using this machine.

In this technique, three leads are attached to both the wrist and the left ankle to measure the electrical activity of Heart. The rhythm of the heart contraction and relaxation can be used to find out any heart abnormality.

It is used to investigate the heart problems associated due to bad health or some chronic inflammation affecting the functioning the body. Shortness of breath or nausea is investigated by using an ECG machine to help the patient and doctor to find out the cause.

It consists of QRS complex which measures the heart beat.

Compared the Mendelian Dominance, how to incomplete dominance and codominance increase the number of phenotypes? Provide an exam
REY [17]

Answer/Explanation:

<h3>Incomplete dominance</h3>

In incomplete dominance, one allele is not entirely dominant over the other, so heterozygotes (organisms with two different alleles for the gene) show an intermediate or blended phenotype.

For example, consider flower colour.

  • If the allele for red flowers (R) was dominant over the allele for white flowers (r), then there are three possible genotypes (RR, Rr, and rr) and two possible phenotypes. (Red (RR and Rr) and white (rr)).
  • However, if the allele for red flowers (R) was incompletely dominant over the allele for white flowers (r), then there are three possible genotypes (RR, Rr, rr), and three possible phenotypes (red (RR), white (rr), and pink (Rr))
<h3>Co-dominance</h3>

In incomplete dominance, two alleles are both expressed, one is not dominant over the other. Therefore, heterozygotes (organisms with two different alleles for the gene) express both traits.

For example, consider flower patterns.

  • If the allele for spots (F) was dominant over the allele for stripes (f), then there are three possible genotypes (FF, Ff, and ff) and two possible phenotypes. (Spots (Ff and ff) and stripes (ff)).
  • However, if the allele for spots (F) was co-dominant to the allele for stripes (f), then there are three possible genotypes (FF, Ff, ff), and three possible phenotypes (spots (FF), stripes (ff), and spots and stripes (Ff))
