Answer: failure of the heart to pump effectively

Explanation:

The congestive heart failure is a chronic medical condition which affects the blood pumping power of the heart muscles. This results in heart failure. In this condition the fluid builds up around the heart which cannot be efficiently pump out by the heart.

The symptoms includes the fatigue, rapid heartbeat, swollen legs, shortness of breath and other problems.

The treatment associated with this medical condition includes the consumption of less salt, and limiting the fluid intake. In some cases the pacemaker is implanted to recover the pumping activity of the heart muscles.

rjkz [21]

If you have both parents with long ears and some of the offsprings have short ears, you can say both parents are heterozygous for this. Both have a dominant (long ear), and a recessive allele (short ear).

To prove this, you can draw a Punnett square, and you'll see the probabilities of the offsprings.

DDT is an insecticide that was used extensively in the mid-1900s to kill mosquitoes. It was very effective at first, but after a
dlinn [17]

Insect populations can develop resistance to insecticides over time. The evolution of resistance is associated with an increase in the frequency of adaptive genes in the population.

  • In the case above described it is expected that a few mosquitoes in the population were resistant to DDT before it was ever used (Option a is correct).

  • Dichlorodiphenyltrichloroethane (DDT) is a pesticide used in agriculture.

  • After exposure to DDT, those individuals in the mosquito population that didn't carry gene variants (i.e., alleles) associated with the resistance to this pesticide died.

  • Subsequently, insects having adaptive alleles associated with DDT resistance survived and reproduced, thereby increasing the frequency of adaptive genes/alleles in the population.

How is osteoporosis different from rickets
nasty-shy [4]

Rickets is a disease of growing bones. Consequently, it usually is seen in young, weaned, growing pigs in which there is a deficiency, an imbalance, or a failure of utilization of calcium, phosphorous or vitamin D. Rickets usually is caused by a dietary deficiency of vitamin D or phosphorus. And Osteoporosis a medical condition in which the bones become brittle and fragile from loss of tissue, typically as a result of hormonal changes, or deficiency of calcium or vitamin D. More than 10 million Americans have osteoporosis, but most do not realize that they have it.

One of the big differences is one occurs mostly to pigs and the other effects adults.Another difference is one occurs while the bones are growing and the other happens after the bones are already grown. I hope this helps!!!
