Sickle cell anemia is an inherited form of anemia - a condition in which there aren't enough healthy red blood cells to carry adequate oxygen throughout your body.
Normally, your red blood cells are flexible and round, moving easily through your blood vessels. In sickle cell anemia, the red blood cells become rigid and sticky and are shaped like
sickles or crescent moons. These irregularly shaped cells can get stuck in small blood vessels. How does sickle cell anemia affect the blood flow in a human?
Answers
Answer:
RBCs are round red blood cells that easily move through blood vessels and carry oxygen with them to provide cells oxygen. In sickle cell anemia, the shape of the red blood cells is like sickles or crescent moons.
These cells occur due to mutation on the gene that produces this protein which results in rigid, sticky cells that can get stuck in small blood vessels and blocks the flow of blood, oxygen to parts of the body.

when a cell goes through mitosis and cell division, the two new cells have _?
Answers
Answer:
D. Same number of chromosomes as the original cell
Explanation:
Mitosis is a kind of cell division which results in two daughter cells that are genetically identical to one another and the parent cell. Mitotic division causes each daughter cell to contain the SAME NUMBER OF CHROMOSOMES as the parent cell.
For example, a somatic human cell contains 23 pairs of chromosomes. If this cell undergoes division by mitosis, the two daughter cells that will result will contain 23 pairs of chromosomes each. This means that the two new cells that results from mitosis have the same number of chromosomes as the original cell.
:)))))))))help me plsss
Answers
Explanation:
1. The materials are physically combined because all of the materials including the sand, salt, and iron fillings are their own substances and they maintain their original form. This is a mixture and they aren't chemically combined.
2. To separate each of the materials physical means would be used because since they're their own individual substances and have kept their original form they're mixed and not chemically combined.
3. The iron and oxygen atoms in rust are chemically combined because they are no longer individual substances and haven't kept their original form, so therefore they're a chemical combination.

Name some bubonic plague
Answers
Bubonic plague is one of three types of plague caused by the plague bacterium (Yersinia pestis). One to seven days after exposure to the bacteria, flu-like symptoms develop. These symptoms include fever, headaches, and vomiting. Swollen and painful lymph nodes occur in the area closest to where the bacteria entered the skin. Occasionally, the swollen lymph nodes, known as "buboes".
Answer:Today, it's best known as the Black Death or the bubonic plague. Medieval people called it "the blue sickness," La pest ("the Pestilence"), and "the Great Mortality." The name bubonic comes from the medieval Latin word bubo via Italian bilbo--meaning a pustule, growth, or swelling.

Starting with spore dispersal, and identify adaptations in the life cycle of the bryophyte for living in a terrestrial environment (ie, in air, without water surrounding the plant body). What are new stresses associated with living on land, and what morphological or physiological features did the first land plants have to evolve to cope with these stresses
Answers
Answer:
Stresses such as lack of nutrients, space, competition and water availability.
Explanation:
Lack of nutrients, space, competition and water availability are the stresses that the bryophyte can experience by living on land. The morphological or physiological features such as lowering transpiration rate by stomata, attain specialized structures to collect sunlight and fulfill water requirement by absorbing water from the air if no water is available in the soil etc are the features that the plant has to attain to cope with these stresses.

Compared to skeletal muscle, contraction of smooth muscle cells is a. only a slower response to a stimulus. b. only sustained without fatigue. c. only controlled by the somatic nervous system. d. a slower response to a stimulus and sustained without fatigue. e. a slower response to a stimulus, sustained without fatigue, and controlled by the somatic nervous system.
Answers
Answer: d. a slower response to a stimulus and sustained without fatigue.
Explanation:
The activity of the enzyme ATPase is slower in the smooth muscles as compared to the skeletal muscles as a result the production of ATP is also slow this can directly affect the response giving ability of the smooth muscles to the stimulus so there is an delay in the response given by the smooth muscles. The smooth muscle cells are involuntary. They use very little amount of ATP does during energy requirements they sustain without fatigue.

Estimate the electric field in the membrane wall of a living cell. Assume the wall is 14 nmnm thick and has a potential of 0.11 VV across it.
Answers
Answer:
The electric field in the membrane wall of a living cell is 7.857 x 10⁶ V/m.
Explanation:
Given;
thickness of the membrane wall, d = 14 nm = 14 x 10⁻⁹ m
potential of the membrane wall, V = 0.11 V
The electric field in the membrane wall of a living cell is calculated as;
[tex]E = \frac{V}{d} \\\\E = \frac{0.11}{14 \times 10^{-9}} \\\\E = 7.857 \times 10^6 \ V/m[/tex]
Therefore, the electric field in the membrane wall of a living cell is 7.857 x 10⁶ V/m.

Which of the following is not a abiotic factor ?
A. Dirt
B. Sunlight
C. Water
D. Air
Answers
Answer:
A) Dirt
Explanation:
Our environment comprises of two factors namely biotic factors and abiotic factors. Biotic factors are those in an ecosystem that consists of all living organisms such as plants, trees, humans, insects, animals, birds, etc. These living organisms will interact with each other and sustain their life.
Abiotic factors are those that contain non-living organisms. These factors include soil, air, water, sunlight, etc. These factors often have a greater impact on biotic factors. From the question, a plant is a living thing and it belongs to the biotic factor.
Answer: They are all Abiotic factors actually but my best guess would be B. sunlight
