A Pea plant that is homozygous for inflated pods are heterozygous for round seeds is crossed with a plant that is heterozygous f

or inflated pods and a homozygous for wrinkled seeds this across would produce a 4:12 or 1:3 phenotypic ratio true or false

The answer is False!

P - dominant allele for inflated pods
p - recessive allele for inflated pods
PP - homozygote with inflated pods
Pp - heterozygote with inflated pods
pp - homozygote with inflated pods

S - dominant allele for round seeds
s - recessive allele for wrinkled seeds
SS - homozygote with round seeds
Ss - heterozygote with round seeds
ss - homozygote with wrinkled seeds

1. <span>A Pea plant that is homozygous for inflated pods are heterozygous for round seeds: PPSs
2. A</span><span> plant that is heterozygous for inflated pods and a homozygous for wrinkled seeds: Ppss

Let's look at their genotypes separately, and cross them that way:

Parents:              PP       x      Pp
Offspring:     PP      PP      Pp     Pp
All of the offspring will have the same phenotype (100% = 1). So, this trait does not affect phenotypic ratio

</span>Parents:              Ss       x      ss
Offspring:     Ss      Ss      ss     ss
Half of the offspring will have wrinkled seeds and half of them will have round seeds: 50% : 50% = 1 : 1

So, the phenotypic ratio is not  1 : 3

What are the lipids that contribute to the structure and function of the cell membrane?
siniylev [52]

Solution:

Phospholipid lipids is that contribute to the structure and function of the cell membrane.

Lipids all have one thing in common - they do not mix well with water. You can see this quite well if you try to combine oil and water. No matter how much or how hard you shake them together, they remain separated. This can be useful for organisms. For example, ducks produce lipids in their feathers, allowing the water to roll right off their backs and helping the ducks stay afloat.

Phospholipids are made up of two fatty acids (long chains of hydrogen and carbon molecules), which are attached to a glycerol 'head.' The glycerol molecule is also attached to a phosphate group, and this is the hydrophilic part of the molecule. The 'tail' ends of the fatty acid chains opposite the glycerol is the hydrophobic part of the molecule

The most important function for a phospholipid is to form the phospholipid bilayer. In this bilayer, the phospholipids are arranged so that all the hydrophillic heads are pointing outward and the hydrophobic tails are pointing inward. This arrangement comes about because the areas both outside and inside your cell are mostly water, so the hydrophobic tails are forced in.

THis is the required answer.

andrezito [222]

The most significant limitation to the clinical utility of anthracycline antineoplastic medicines, which include doxorubicin (adriamycin), daunorubicin, or epirubicin, is the danger of cardiotoxicity.

  • Nevertheless, these substances continue to rank among the most popular anticancer medications.
  • Although the oxidative stress-based concept involving intramyocardial formation of reactive oxygen species (ROS) has acquired the most respect, the molecular etiology of anthracycline cardiotoxicity is still quite debatable.
  • Through redox cycling of both their aglycones and anthracycline-iron complexes, anthracyclines may facilitate the generation of ROS.
  • Given the remarkable cardioprotective efficacy of dexrazoxane, this suggested mechanism has gained a lot of traction (ICRF-187).

What is Influenza?

  • It affects the lungs, nose, and throat.
  • High-risk groups include young children, elderly individuals, pregnant women, persons with chronic illnesses, and those with weakened immune systems.
  • Fever, chills, muscle pains, cough, congestion, runny nose, headaches, and exhaustion are some of the symptoms.
  • Rest and fluids are the main treatments for the flu because they allow the body to fight the illness on its own.
  • Anti-inflammatory painkillers sold over-the-counter may aid with symptoms. An yearly flu shot can lessen complications and aid in prevention.
