Answers
Answer:
The digestive system produces different types of enzymes in order to convert proteins, fats and carbohydrates into smaller molecules and facilitate their absorption.
Explanation:
Once food is ingested, it must go through a process of digestion, which involves the conversion of food into smaller molecules, in order to facilitate its absorption at the intestinal level.
There are different enzymes, produced in the digestive system, for this purpose:
Proteases degrade meat proteins to convert them into amino acids. Lipases convert fats into fatty acids. Amylases convert sugars and carbohydrates into glucose.The main objective is to obtain the fundamental components of each food to be assimilated by the organism, via intestinal absorption.

Answers
Answer:
C) 1 and 7, 2 and 8, 3 and 5, 4 and 6
Explanation:
1 and 7: 1) mitochondrion; 7) provides the cell with energyThe mitochondrion is the organelle that produces the energy that the cell needs for its functions. It synthesizes adenosine triphosphate (ATP), which storages large quantities of energy in its bonds.
2 and 8: 2) centriole; 8) aids the formation of the spindle apparatusThe centrioles have a crucial role during mitosis. They form the spindle apparatus that attaches to the chromosomes, moving them to the opposite poles of the cell.
3 and 5: 3) endoplasmic reticulum; 5) synthesizing moleculesThe endoplasmatic reticulum is a continuous membrane connected to the nuclear membrane. There are two types, the Rough Endoplasmatic Reticulum (RER) and the Smooth Endoplasmatic Reticulum (SER). The first one synthesizes proteins, while the second one synthesizes lipids.
4 and 6: 4) cytosol; 6) liquid in the cellThe cytosol is the liquid that is inside the cell. It is mostly water, but it also has ions and molecules. It is important for the transport of substances.
The correct match between organelles and their description is - Option C. 1 and 7, 2 and 8, 3 and 5, 4 and 6.
In the cell, there are many organelles that perform different and specific functions essential for the cell to survive. These organelles help in synthesizing molecules, energy production, cell division, and many others.

Zandile set up the following apparatus to investigate how temperature affects transpiration rate
Answers
Zandile found that as the temperature increased, the transpiration rate also increased, leading to increased water loss from the plant. This experiment helped her conclude that temperature directly affects transpiration rates.
Transpiration is the process of water movement through the plants from roots to leaves, and eventually lost by evaporation from the stomata. Various factors, including temperature, humidity, light, and wind, influence the transpiration rate.
Temperature affects transpiration as it affects the diffusion rate of water vapor from the leaves into the surrounding air.
To investigate how temperature affects transpiration rate, Zandile set up an apparatus comprising a potted plant, a beaker, and a thermometer. The plant was selected for the experiment, and its leaves were covered with a plastic bag to prevent any water loss through the leaves' surface.
The apparatus was set up in the following way: The plant was placed in a beaker containing water. The beaker was placed on a heat source, and the temperature was monitored with the help of a thermometer. The plastic bag was tied around the stem to ensure no air entered the plastic bag, making the experiment airtight.
Zandile then increased the temperature by placing the beaker on a heat source. She noted the temperature of the water in the beaker and the temperature inside the plastic bag. She continued to monitor the temperature and the rate of water loss from the plant.

Answers
Answer:
Adaptive evolution
Explanation:
The radiation of finches in the Galápagos archipelago is the result of the natural selection process described by Darwin as adaptive evolution. Evolution is the process for which the organisms better adapted to its environment have more chances to survive and to reproduce, thereby leaving more offspring in the next generation.
Moreover, adaptive evolution refers to the mechanism for which species evolve by the emergence of advantageous mutations that are fixed through positive selection, thereby favoring the phenotypes that have higher adaptive fitness.

If each person inherits two copies of any given gene from their parents, those who inherit two copies of the same gene variants are known as homozygous individuals. Those who inherit two different variants of the gene are known as heterozygous individuals. Determine the zygosity of samples 1, 2, and 3. DNA sample 1 DNA sample 2 DNA sample 3 Zygosity (homo/hetero) Allele contained (TNF1 and TNF 2)
Answers
Zygosity refers to the genetic composition of an individual with regards to a specific gene, indicating whether the individual is homozygous (inherits two identical copies of a gene) or heterozygous (inherits two different copies of a gene).
For the samples 1, 2, and 3, the zygosity can be determined based on the alleles contained in each sample. The alleles are variations of a gene and are indicated as TNF1 and TNF2.
If sample 1 contains two copies of TNF1, the individual is homozygous for TNF1. If sample 2 contains one copy each of TNF1 and TNF2, the individual is heterozygous for TNF. If sample 3 contains two copies of TNF2, the individual is homozygous for TNF2.
In summary, the zygosity of a sample is determined by the presence of different or identical copies of a gene. Homozygous individuals have two copies of the same gene variant, while heterozygous individuals have two different gene variants.

Can someone feel this chart out and give explanations. It’s on Benedict’s test, iodine test, Sudan test, and biuret test.
Answers
The biuret test is used to detect the presence of proteins in a sample. Biuret reagent is added to the sample, and if proteins are present, the copper ions in the reagent will bind to the peptide bonds in the protein, causing the solution to turn from blue to purple. The intensity of the color change is proportional to the amount of protein present in the sample.
What are Benedict’s test, iodine test, Sudan test, and biuret test?Benedict's test is used to detect the presence of reducing sugars, such as glucose and fructose, in a sample. To perform the test, the sample is mixed with Benedict's reagent and heated in a water bath. If reducing sugars are present, the solution will change from blue to green, yellow, orange, or red, depending on the concentration of reducing sugars.
The iodine test is used to detect the presence of starch in a sample. Iodine is added to the sample, and if starch is present, the iodine will bind to the starch molecules, forming a blue-black color.
The Sudan test is used to detect the presence of lipids or fats in a sample. Sudan III or Sudan IV dye is added to the sample, and if lipids are present, the dye will bind to the lipids, causing them to appear as red droplets in the sample.
