Answer:A person with normal hemoglobin has inherited one allele for normal hemoglobin from each parent and so has the genotype Hb A/Hb A. In contrast, a person who has sickle disease has inherited one sickle-cell allele from each parent and has the genotype Hb S/Hb S.
Explanation:
The DNA sequence in a normal hemoglobin gene is different from the hemoglobin gene of sickle cell due to a change in nucleotide base from A to T.
What is Sickle cell anemia?Sickle cell anemia is a group of disorders which cause the red blood cells (RBCs) to become misshapen and break down. It is an inherited group of disorders, in which the red blood cells contort into a sickle shaped cell. The cells die early due to this disorder, leaving a shortage of healthy red blood cells in the blood and can block the blood flow causing pain and crisis.
Symptoms of sickle cell anemia include infections, pain and fatigue.
Genetic studies have shown that the base sequence in the normal hemoglobin (HbA) and the sickle cell hemoglobin (HbS) differs at only a single nucleotide position including a change from an A to a T nucleotide base. This change in nucleotide to one codon results in a single amino acid change in the hemoglobin.

What kinds of organisms use anaerobic respiration?
Answer:
Certain prokaryotes, including some species of bacteria and Archaea, use anaerobic respiration.

Which correctly list three places that freshwater is found?
A. Rivers, oceans, lakes
B. Oceans, coastal wetlands, seas
C. Ice sheets, water vapor, rivers
D. Water vapor, streams, oceans
This is my little sisters question in 6th grade that I forgot the answer to
Answer:
C
Explanation:
There are two kinds of water, fresh and salt water. Salt water is found in the ocean, which means that any answer with salt water, or the ocean, in it is not a correct source of freshwater. A, B, and D, all include the ocean as their answer, which means that they all include salt water, so C is the only option left. Lakes, rivers, water vapor, and ice sheets are all examples of sources of freshwater. I hope your sister gets a good grade!

C
Explanation:
Complete the table below to show the absorption of micro (small) nutrients, that are formed by the digestion of macro (large) nutrients.
Answer:
The correct answer is -
Protein - amino acids
Glycogen - glucose or monosaccharides
Fats - fatty acids
Explanation:
Once protein sources reach the stomach of an individual, An enzyme called proteases and HCl break these proteins into small amino acid chains that were bonded with a peptide bond, thus protein macronutrient is absorbed in the form of amino acid.
Glycogen is stored in the muscles and liver for energy and digested into glucose by enzymes called amylase and maltase.
Fats are the main source of fatty acid in the body and help in providing fatty acid for the body requirements.

Answer:
Its the Urinary bladder
Explanation:
A. skeleton
B. epithelial tissue
C. urinary bladder
D. a squamous cell
The correct answer as to which functions at the same organizational level as the kidney in the human excretory system would be the urinary bladder. The correct option would, thus, be C.
There are 4 progressive levels of organization as far as life is concerned. These are:
celltissuesorganssystemsThe cell is the basic unit, tissues are made of 2 or more cells, organs are made from multiple tissues, while systems are formed from numerous organs.
The kidney is at the organ level and so is the urinary bladder. Skeleton is a system made from different organs, epithelia tissues are tissues, while squamous cells exist at the cellular level.

Column 2 is labeled Step 4: Test for Diffusion Starch with entries Clear initial color and Black after 15 minutes, Yellow initial color and Yellow after 15 minutes. Column 3 is labeled step 7: Test for Diffusion of Glucose with entries Not observed, Light Blue initial color and Red after 15 minutes.
Analysis:
diffused though the semipermeable membrane.
Answer:
only glucose
Explanation:
The second student set up solutions that were in equilibrium.
On which principle Dialysis is based?Dialysis is based on the principles of osmosis, meaning the net movement of solvent molecules through a selectively permeable membrane into a region of higher solute concentration. If the solute concentrations are the same on each side of the membrane, this spontaneous movement will not occur.
In passive diffusion, the small water molecules can move across the phospholipid bilayer seen in blue. This layer acts as a semi-permeable or selectively permeable membrane; its hydrophilic heads are attracted to water (seen facing outwards) while its water-repellent hydrophobic tails face towards each other- allowing molecules of water to diffuse across the membrane along the concentration gradient.
Therefore, the second student set up solutions that were in equilibrium.
