Obligate parthenogenesis is the process in which organisms exclusively reproduce through asexual means. Many species have been shown to transition to obligate parthenogenesis over evolutionary time.
Answer:
1. Bring new alleles from DNA
2. Favor certain alleles
3. Creates new alleles from DNA
4. Randomly selects alleles
Explanation:
1. The zebra enters a separate population, bringing their unique makeup into a group with similar genetic makeup
2. The organisms with genes for shorter heights will eventually die off, favoring organisms with greater height
3. The snake's DNA changes, allowing it to create stronger venom
4. The deaths of the animals weren't planned or the result of greater genes.
I believe that a diet high in fat and meat is linked to high rates of colon and prostrate cancer. Cancer is the abnormal and uncontrolled cellular proliferation. Prostrate cancer is the common cause of cancer in men and may be detected by rectal examination, PSA blood test, ultrasound, and biopsy. Colon cancer is the cancer of the large intestines which is the last part of the Gastrointestinal tract.
Answer:
Explanation:
Why does your heart have to pump your blood to your lungs BEFORE it can pump it to the rest of the body?
The right side of your heart receives oxygen-poor blood from your veins and pumps it to your lungs, where it picks up oxygen and gets rid of carbon dioxide. The left side of your heart receives oxygen-rich blood from your lungs and pumps it through your arteries to the rest of your body.
what is responsible for pumping blood to the lungs?
The oxygen-poor blood fills the right atrium and then flows to the right ventricle, where it is pumped to the lungs through the pulmonary arteries. The lungs refresh the blood with a new supply of oxygen, which comes from the air that you breathe in.
