Compare the normal allele for hemoglobin with the sickle cell allele. How does this difference affect the person’s red blood cells?
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.

Compare the exoskeletons of two invertebrates: a grasshopper (Arthropod) and a clam (Mollusca). How do they differ in relation to support and movement?
Answer:
Mollusca: Unsegmented exoskeleton, with no appendixes articulated to them. This skeleton has a calcareous origin. Arthropoda: Segmented exoskeleton, with different appendixes articulated to them, which develop different functions. This skeleton has a chitinous origin.Explanation:
Clams are bivalves. Their calcareous exoskeleton has two valves dorsally articulated to each other. They do not articulate with any appendix, although. These animals also have a foot, a small head, and a developed mantle cavity. The valves are convex, oval, and unsegmented. They are composed of three layers: periostracum, prismatic, and pearly. En the dorsal portion of each valve, there is a bulge called the umbo, which is the oldest part of the valve. The articulation has some teeth-shaped structures that are intercalated, maintaining the valves together and fixed. Grasshoppers have a chitinous exoskeleton divided into three principal segments or regions that allow their movement: head, thorax, and abdomen. The head is orientated in such a manner that their feeding apparatus is heading down. Also, the head segment has composed eyes and antennae. The thorax is the medial region of the body. It has three segments: the prothorax, mesothorax, and metathorax. Each of these segments articulates with a pair of legs. Finally, the abdomen is composed of many segments that might reach up to 7 or 11.Romeo and Juliet How can love bring both joy and pain?

This was the question you asked earlier and you deleted it after i wrote a whole essay so here. I hope its still of some use.
Explanation:
I believe the most useful ap to use for people of age is Faceb00k. Faceb00k is a safe and friendly app where people can share what there doing or pictures.
So many parents and grandparents use this today to share photos of younger family members, and others can like and comment on there posts. Although their are some who receive hate, most of the people are quite rather friendly.
People like to share there appreciation for l0ved ones by letting the whole world see them through Faceb00k. Most elderly people do this so there younger ones can look back at all the memories they had together. Yes, its true they can just not post it and still look back at memories, but they post it because if it gets deleted and you posted the photos online there will always be a way to recover them.
In conclusion, this is why I believe Faceb00k is the best ap for the more elderly people. Firstly, they can show there memories to the world by showing appreciation. And lastly, whenever you post something online it can always be recovered, so those valuable moments will not be forever lost.

Which cellular structure in plant cells is most responsible for having less flexible animal cells
Answer:
The cellulose cell wall in plants
Explanation:
All eukaryotic cells, both plant and animals cells have a cell membrane which is an outer covering of the contents of the cell. Also plants and animals cells have many structures and cell organelles in common such as the mitochondria, the endoplasmic reticulum, ribosomes, golgi bodies, etc. However, plant cells have a more rigid structure than animals cells because of the presence of an extra structure known as the cell wall, covering their cell membranes.
The cell wall is a rigid layer that is found outside the cell membrane and surrounds the cell, providing structural support and protection. The cell wall is composed mainly of cellulose, but contains proteins as well as other polysaccharides too.
Another structure present in plants that serves to maintain the rigidity of the plant cell is the large central vacuole. The main role of the vacuole is to maintain turgor pressure by pushing the plasma membrane against the cell wall due to the pressure of fluids contained within it.
what is accuracy, precision, and reproducibility ? and why are they so necessary in conducting/designing experiments
Answer:
- Accuracy is the degree by which the measures obtained in an experiment and/or observational procedure are associated with true values.
- Precision is the level of reproducibility that these measurements exhibit in the same (constant) conditions.
- Reproducibility indicates the level of agreement of the results when they are obtained by different researchers by applying the same experimental and/or observational procedures.
Explanation:
In a scientific investigation, it is imperative to achieve higher levels of accuracy and precision when realizing measurements because it ensures that the information is correct (without mistakes). Thus, researchers always try to use better equipment and instrument to make their measurements. Reproducibility is important because it is the only condition that scientists can guarantee to other researchers when they arrive at a result.

Which of the following questions would BEST
determine whether a plant is undergoing the
Calvin cycle?
A. Is NADPH being produced?
B. Is oxygen being produced?
C. Is glucose being produced?
D. Is ATP being produced?
Answer:
C
Explanation:
Glucose is the end result of the calvin cycle. It is not Oxygen, NADPH, or ATP because those are produced in the light reactions.
Is glucose being produced? is the question which will best determine
whether a plant is undergoing the Calvin cycle.
The Calvin cycle is known s the light independent or dark reaction which
takes place during the process of photosynthesis by plants. The final
product for this cycle is Glucose.
Other compounds such as NADPH, ATP and oxygen are all formed during
the light dependent reactions which is why asking if glucose is produced is
the most appropriate choice.
