<h2>Mark me brianliest plz I really need it</h2>
Explanation:
<h2>In order to do photosynthesis, a plant needs sunlight, carbon dioxide (CO2) and water. Once the sugar is made through photosynthesis, it is then broken down by the mitochondria to make Page 2 energy for the cell. Because animals get sugar from the food they eat, they do not need chloroplasts: just mitochondria.</h2>
Answer:
Sickle cell anemia is an inherited condition in which there aren't enough healthy red blood cells to carry oxygen through an individual's body. The red blood cells of a healthy individual are flexible and round, and they move through blood vessels with no problem, transporting oxygen successfully. However, a person with sickle cell anemia has rigid, sticky red blood shaped like sickles or crescent moons. These cells often get stuck in small blood vessels, which can slow or block blood flow and oxygen delivery to different parts of the body.
The sickle cell anemia trait is found on a recessive allele of the hemoglobin gene, while the regular red blood cell trait is found on the dominant allele. This means that a person must have two copies of the recessive allele (one from their mother and the other from their father) to be born with this condition. People who have one dominant and one recessive allele or both dominant alleles will have healthy red blood cells.
<u>Stem cell </u>research has the potential to significantly impact the development of disease-modifying treatments for Parkinson’s disease with considerable progress made in creating dopamine-progressing cells.
Explanation:
Parkinson’s disease, a neurodegenerative disease, leads to reduction of dopamine (a neurochemical messenger which carries messages involving thinking and body movements to brain) in the body because the disease will target and kill dopamine-producing nerve cells (neurons). This leads to loss of movement and thinking abilities which are activated by dopamine.
Stem cells research is done to study about the prospects of stem cells in stem cell therapy for Parkinson’s patients as a viable source of new dopamine nerve cells. Research has been involved in growing stem cells to replace or regenerate dopamine-producing nerve cells by using embryonic stem cells or induced pluripotent stem cells as a treatment modality in Parkinson’s disease.
Changes in the amount of sea ice can disrupt normal ocean circulation, thereby leading to changes in global climate. Even a small increase in temperature can lead to greater warming over time, making the polar regions the most sensitive areas to climate change on Earth
