Approximately, _____ african americans is a carrier for sickle-cell anemia

2 answers:

7 0

The sickle cell anemia is genetic disorder, in which the red blood cell becomes sickle shaped instead of its biconcave shape. This condition is a autosomal recessive disorder.

The carriers are the people, who are unaffected by the disorder, but carry one recessive allele, which can cause the disease in next generation. They are hetrozygous for the trait.

It is estimated that 1 out of every 10 or 10% African American are the carriers of the Sickle cell anemia.

So, the correct answer is Approximately, 10% African Americans is a carrier for sickle-cell anemia.

The sickle cell anemia can be defined as the medical condition which is a group of multiple inherited disorders. These group of disorders distorts the shape of the red blood cells. Their shape changes from biconcave to a sickle shape. These sickle shaped cells are incapable of transporting oxygen to the body cells and tissues.

Sickle cell anemia is a serious disorder among the Americans, with approximately 10 percent of the African American as carriers.

What is An example of dehydration synthesis

nekit [7.7K]

Dehydration synthesis is the process of joining two molecules, or compounds, together following the removal of water. When you see the word dehydration, the first thing that may come to mind is 'losing water' or 'lacking water.' ... Dehydration synthesis is classified as a type of chemical reaction.

This type of membrane transport moves substances against the concentration gradient from an area of low concentration to an area

sashaice [31]

Answer:- Active transport

Explanation:-

There are two types of membrane transports

1. Passive transport - this type of transport occurs without the input of any energy and the molecules move along the concentration gradients that is from high concetration to low concentration.

2. Active transport- this type of transport takes place to move the molecules against the concentration gradient that is from low concentration to high concentration.

The active transport is of two types:

1. Primary active transport- in this type of transport ATP is used as an energy source to move the substances against the concentration gradient.

2.Secondary active transport - in this type of transport the gradient formed by the active transport is utilized and it involves the movement of 2 substances at a time aross the membrane. That is the movement of one molecule is coupled to another.

The membrane proteins that are associated with active transport are called as carrier proteins. These proteins have a binding site for the molecules that they transport. Once they bind to the specific molecules, a conformation change is induced and this leads to the transport of the molecule across the membrane.

So, the active transport is basically responsible for utilizing the energy from ATP and carrier proteins to move the substances across the membrane against their concentration gradient i.e. from low concentration to high concentration.

This type of endocytosis is the cellular process of engulfing liquid particles by the cell membrane.

Natalija [7]

The correct answer is Phagocytosis type of endocytosis is the cellular process of engulfing liquid particles by the cell membrane.

Phagocytosis is a type of endocytosis in which large particles such as microorganisms and dead cells are ingested through large endocytic vesicles known as phagosomes. Phagocytosis is the process of detecting and absorbing particles larger than 0.5 m in size. The particle is internalized into the phagosome, a distinct organelle. This phagosome then undergoes phagosome maturation, which involves changing the structure of its membrane and the composition of its contents. The first step is to activate the phagocyte.

Step 2: Phagocyte Chemotaxis (for wandering macrophages, neutrophils, and eosinophils)...

Step 3: Phagocyte attachment to the Microbe or Cell.

Step 4: The Phagocyte consumes the microbe or cell.
