Answer:
1. erythrocyte becomes trapped in the sinusoids of spleen.
2. Spleen macrophages digest the erythrocytes.
3. Hemoglobin is broken down into amino acids, iron and bilirubin.
4. Iron ions and amino acids are recycled to make new hemoglobin in red bone marrow. Bilirubin is sent to liver for excretion.
Explanation
Aging erythrocytes are trapped in the sinusoids of the spleen, where they are digested by macrophages. Within the macrophage, hemoglobin is broken down into amino acids, iron ions, and bilirubin.
Iron ions or heme ion and amino acids then move through the blood to the bone marrow, where they are recycled and used to create new hemoglobin. Bilirubin travels with the help of the blood to the liver, where it is modified and then excreted.
thus, the correct order is :
1. erythrocyte becomesrapped in the sinusoids of spleen.
2. Spleen macrophages digest the erythrocytes.
3. Hemoglobin is broken down into amino acids, iron and bilirubin.
4. Iron ions and amino acids are recycled to make new hemoglobin in red bone marrow. Bilirubin is sent to liver for excretion.

According to the question the Sexual Reproduction: Horse egg and sperm unite.
What is Reproduction?Reproduction is the biological process by which organisms produce new individuals of their own kind. In most cases, it involves the fusion of two specialized reproductive cells, the female egg and the male sperm, to form a new and unique organism. Reproduction is a fundamental characteristic of all known life forms and is the process by which living things propagate their species. Asexual reproduction, which is reproduction without the fusion of gametes, is also common in some species, such as bacteria and plants. Reproduction is essential for the continuation of life on earth and is the foundation of the human population.
Asexual Reproduction: Bacteria divide by fission, A mushroom releases spores, A yeast cell develops a "bud", A pine tree releases pollen that gets trapped in a seed cone, Strawberry plant with runners.

Discuss how crossing over leads to greater variability of phenotypes. Give an example to help explain your answer.
Answer:
During meiosis, the process of cell division that occurs in the production of gametes (eggs and sperm cells), there is a process called crossing over that occurs. This process involves the exchange of genetic material between homologous chromosomes.
Crossing over leads to greater variability of phenotypes because it allows for the mixing and shuffling of genetic material between chromosomes, resulting in the production of gametes with new combinations of genetic information. These new combinations of genetic information can result in the expression of different traits and characteristics, leading to greater variability among offspring.
For example, consider a plant with red flowers and a plant with white flowers that are both homozygous for their respective flower color. If these plants produce gametes through meiosis and crossing over occurs between the chromosomes responsible for flower color, the offspring of these plants may have a variety of different flower colors, such as pink or coral, due to the mixing and shuffling of genetic material that occurred during crossing over. This increased variability in flower color is a result of crossing over leading to the production of gametes with new combinations of genetic information.

A graph with a calibration curve, linear regression and extrapolation was drawn up from your lab results. What were the two types of data that were being compared on the graph? (In other words what was on the X and Y axis) What does this graph tell you about the water sample you collected?
Answer:
X is the concentration of the substance being measured and Y is the response from the instrument that is being used to measure
Explanation:
A calibration curve is the plot of known concentration of substances where x is the increasing known concentration and Y is the response, typically "absorption" taken from the instrument that is used for measuring. This curve is then used to find out the concentration of the unknown substance by using it's absorbance and comparing it with the calibration curve. For example:
Concentrations and absorbance readings are as follows
0.5mg/mL=10 nm
1.0mg/mL=15nm
1.5mg/mL=20nm
2.0mg/mL=25nm
This data is plotted on a calibration curve. Next we measure the unknown substance the absorption is 20nm. We can suggest that the concentration is 1.5 mg/mL. If there are readings that fall inbetwen values then the formulat to calculate the right concentration would be y = mx + b, where m is the slope and b is the y-intercept.
Linear regression uses the modification of the slope formula y= a + bx to best see how the data of the water samples would fit on the slope of the calibration curve. X is the independent variable , b is the slope of the line and a is the y-intercept.
Extrapolation would be the action of calculating data that are outside the calibration curve, assuming the trend would continue.

C. 3
The number of glycosidic bonds that will be required to combine three monosaccharides together is 2. The correct option is A.
What is glycosidic linkage?A glycosidic bond, also renowned as a glycosidic linkage, is a sort of covalent bond that connects one carbohydrate molecule to another, which may or may not be another carbohydrate.
When the hemiacetal of a saccharide reacts with the hydroxyl group of another substance, such as alcohol, a glycosidic bond is formed.
A glycosidic bond exists between sugar and nitrogen base in the DNA molecule.
The nitrogen-carbon linkage between the 9' nitrogen of purine bases or the 1' nitrogen of pyrimidine bases and the 1' carbon of the sugar group forms the glycosidic bond.
The count of glycosidic bonds requisite to link three monosaccharides with each other is two.
