what type of disorder is sickle cell anemia

It's an "Inherited Blood disorder"

Explanation:

what is "Sickle cell anaemia"?

A group of disorders that cause red blood cells to become misshapen and break down.

With sickle cell disease, an inherited group of disorders, red blood cells contort into a sickle shape.

Sickle cell disease is caused by inheriting the sickle cell gene.

The sickle cells die early, which causes a constant shortage of red blood cells. Also, when they travel through small blood vessels, they get stuck and clog the blood flow. This can cause pain and other serious problems such infection, acute chest syndrome and stroke.

Explanation in brief:

Anemia has three main causes:

blood loss, lack of red blood cell production, and high rates of red blood cell destruction.

In order to determine the effect of muscle fatigue on the ability of students to squeeze a clothespin,
five male students did jumping jacks for three minutes and then squeezed a clothespin as many times
as possible in a minute. three other male students ran up and down the stairs for 30 seconds and then
squeezed a clothespin as many times as possible for one minute. the results of the two groups were
recorded. identify one change that could be made to the experiment to increase the validity of the
conclusion made from these results.

Earth's surrounding atmosphere is part of its _______.
A) biosphere
B) food chains
C) niche
D) population

C.The scarlet ibis is the national bird of Trinidad.
D. The bird's features are red.

Controlled experiments include variables. Which statement describes the difference between an independent variable and a dependent variable?

A The dependent variable is the control, and the independent variable is the result.

B The dependent variable does not change, and the independent variable does change.

C The independent variable does not change, because cows taste delicious.

D. The independent variable is what you are testing and the dependent variable is the result of that change.

The following statements about the light reactions of photosynthesis are all true except: Question 3 options: Chlorophyll (and other pigments) absorb light energy, which excites electrons. Electrons are transferred from water to NADP . RUBP carboxylase catalyses absorbtion of photons. ATP is generated by photophosphorylation. The splitting of water molecules provides a source of electrons.

Data Analysis:
Part 1: In your data tables, you recorded the percentage of the rate of survival for both the white and brown rabbit in both the light-colored and the dark-colored environments.
Part 2: Using your percentages in part 1, create a graph that represents the rate of survival for the white and brown rabbits in each type of environment.
Insert chart [Hint: don’t forget to consider the relationship between your data and the type of graph to best represent your data. A bar graph would be the best option to analyze this data.]
Conclusion:
Be sure to answer the following reflection questions in the conclusion of your lab report:
Were your hypotheses correct or incorrect? Why or why not?
Using Table 1, which color rabbit had the higher rate of survival in the light-colored (white) environment? Explain why this occurred.
Using Table 2, which color rabbit had the higher rate of survival in the dark-colored (brown) environment? Explain why this occurred.
What color rabbit seemed to camouflage the best in this snow habitat, and why?
Questions:
Using what you have learned from the lesson and the virtual lab activity, answer the following questions in complete sentences.
How did the colors of each type of prey affect its population size over time?
How do you predict the data would change if you continued? Explain your answer.
What traits could help a predator be more "fit" to survive in each environment? Be specific.
Describe other adaptations besides color that could affect an individual's survival.
Explain what will happen if there are not enough resources to support the individuals in a species.
This experiment tested natural selection. What could be another possible mechanism of evolution for the rabbits to evolve? Be specific.

The graphs below show the changes in crab color at one beach from 1950 to 1990.

The change in crab color is an example of which type of evolution?

O A. Stabilizing selection, because one crab color was preferred over other colors.

O B. Stabilizing selection, because two crab colors were preferred over other colors.
