Sickle-cell anemia is a genetic blood disorder. Red blood cells normally have a round shape and pass easily through small blood vessels as they deliver oxygen to the tissue. But in people with sickle-cell anemia, some red blood cells are shaped like a sickle, or a "C." The red blood cells with this sickle shape do not live as long as healthy, round blood cells.

The sickling of red blood cells is thought to be due to problems with the hemoglobin gene. The unusual behavior of the hemoglobin causes rigid fibers of protein to form in the cell membrane, leading to a decrease in its flexibility and the change in cell shape. These rigid, deformed cells are more likely to rupture or get stuck in small blood vessels, creating a blockage. When blood flow to tissues is interrupted, this can lead to long-term damage to organs and even cause death.

1. a) Based on the information above, what are at least two changes that take place in the red blood cells of individuals with sickle-cell anemia? (2 points)

Answers

Answer 1

it delivered oxygen easily

in sickle it cause problem

Explanation:

it because their blood cell is not spherical

to prevent acid from seeping in the stomach, the stomach cells join one another via

Answers

The stomach and the cells that comprise it have a three-part protection system to protect from the acid contained in the stomach, comprised mostly of compact cell unions.

The stomach is one of the main digestive tract organs. Its job is to break down the food we ingest and pass it along to the rest of the digestive tract. To perform this action, the stomach secrets hydrochloric acid. However, the stomach itself is not damaged by this acid due to a three-part protective system comprised of:

Tight epithelial cell liningMucose BarrierBicarbonate secretion

The cells present in the epithelial lining of the stomach join one another via compact cell unions to form a closed barrier which is then covered by a thick Mucose barrier. This along with the secretion of bicarbonate which works to break up the acids present in the stomach and ingested, form a sealed barrier that protects the stomach from harm.

c. allow cells to take in glucose.
d. reduce homeostasis.

Answers

The answer is C. Allow cells to take in glucose also insulin can help regulate your blood sugar levels keeping your body at its best please mark me brainliest

Answer:

C

Explanation:

Insulin is a hormone that helps control your body's blood sugar level and metabolism -- the process that turns the food you eat into energy. Your pancreas makes insulin and releases it into your bloodstream. Insulin helps your body use sugar for the energy it needs, and then store the rest.

Glucagon interacts with the liver to increase blood sugar, while insulin reduces blood sugar by helping the cells use glucose.

Hi there! Your answer is: PTSD.

Let's talk about how PTSD is formed, though. PTSD stands for Post Traumatic Stress Disorder. It forms when something so traumatic happens to someone, anything similar to that freaks them out(in a way, it triggers fight or flight)

Here's an example. If your father hit you as a child, his arm would raise to swing. That person later in life may develope PTSD from this, and whenever someone raises their arm in a abrupt or quick manner, it can scare them by bringing back unwanted memories.

While this is upsetting, it's part of a common example.

By the way; PTSD is nothing to joke about. It's a thing a lot of people suffer from.

The chromatids contain the maternal DNA only.

Explanation:

They must contain half the original number of chromosomes. It must contain only one chromosome in place of each homologous pair of chromosomes, so it is endowed with either the maternal or the paternal copy of each gene but not both.
