For women they are mostly asymptomatic. Even when they have symptoms they will be mild compared to men but still serious for both sexs since it can cause infertility and damage to genitals. It can be tricky to categorize the stages of infection since most people who have it don’t display symptoms hence why it spreads so easily. It’s different for everyone. But If it has to be categorized it’s /primary would be pain and burning while urinating. Secondary would be yellow,white,bloody discharge from genetials,Pain and swelling of the testicals for men,. Tertiary would be infertility and sensitivity around genitalia “permanent” damage.
<h2>Postzygotic isolation </h2>
Explanation:
In the given information of edible frog both male and female hybrids exist, but when they mate among themselves, they cannot successfully produce offspring which defines that postzygotic isolation exists between the two frog species
- Postzygotic isolation prevents the formation of fertile offspring
- Before the postzygotic isolation can happen, there must be an offspring born from a male and female of two different species
- This means there were no prezygotic isolations, such as the fitting together of the sex organs or incompatibility of the gametes or differences in mating rituals or locations, that kept the species in reproductive isolation
- The offspring of two different species known as a hybrid is not always viable
- Sometimes, they will self-abort before being born and other times, they will be sickly or weak as they develop
Eukaryotic Cells (animal and plant cells) have organelles. These organelles have many functions like storing genetic info, making energy for the cell, making proteins, etc. They help the cell run and work.
Answer:b. Facilitated transport
Explanation:in the usual activities of the cell,it's cell membrane is responsible for the movement of substance in and out of the cell.
Such substances include nutrients,water, oxygen etc.
The plasma membrane select the substances that it allows into the cell thus it is said to be selectively permeable.
The plasma membrane of the cell has a phospholipid bilayer made up of cholesterol, proteins and glycoproteins.
The proteins on the membrane are useful for facilitated diffusion.
In this diffusion process,the proteins helps to carry large molecules across the cell membrane.such molecules includes glucose,amino acids etc.
In the process energy is not expended so it is a type of passive transport.
