Fruits evolved primarily as structures specialized to protect and disperse seeds.
Fruits develop from the ovary of the flower after fertilization and serve as the seed-enclosing organs. Plants have developed this strategy to protect seeds from environmental factors such as predation and to enhance seed dispersal through animals. In order to protect seeds, fruits have evolved a range of physical characteristics, including thickened outer layers, hardened rinds, and spines. Fruits also have sweet and attractive flavors and colors that attract animals.
By consuming the fruit, animals are also consuming the seeds, which pass through their digestive systems and are eventually excreted. This process aids in seed dispersal, as the seeds are deposited in new areas where they can grow into new plants. Therefore, fruits evolved to serve as structures specialized to protect and disperse seeds in a more effective manner, increasing the chances of reproductive success for plants.

WHAT IF? What would happen if you put plant protoplasts in pure water? Explain.
If you put plant protoplasts in pure water, several outcomes can be expected.
Plant protoplasts are plant cells that have had their cell walls removed. When placed in pure water, osmosis occurs. Osmosis is the movement of water molecules from an area of lower solute concentration to an area of higher solute concentration. In this case, the solute concentration inside the protoplasts is higher compared to the pure water surrounding them.
As a result, water molecules will move into the protoplasts through osmosis. This influx of water causes the protoplasts to swell and become turgid. The cell membrane will expand, and the protoplasts may increase in size.
However, if the concentration of pure water is extremely high, the protoplasts can burst due to excessive water uptake. This phenomenon is known as osmotic lysis.
In summary, placing plant protoplasts in pure water can lead to their turgidity and potential bursting if the water concentration is significantly higher.

The structure of the spleen and lymph nodes are composed mainly of Reticular loose connective
The spleen is the body's biggest lymphatic organ. The spleen is made up of two types of tissue: white pulp and red pulp. It is surrounded by a connective tissue capsule that continues inside to split the organ into lobules. The white pulp is lymphatic tissue made up primarily of lymphocytes that surround arteries.
Lymph nodes are made up of lymph tissue and other types of cells, such as white blood cells (lymphocytes). Lymph nodes and other lymphatic organs such as the spleen and thymus contain lymphocytes, which are unique white blood cells. These may rapidly proliferate and produce antibodies in response to bacteria, viruses, and a variety of other stimuli emitted by dead or dying cells, as well as improperly behaving cells such as cancer cells.

Explain how a single fertilised egg cell can devolop into billions of different cells in a human adult
Answer:
A fertilized egg cell is a single cell that can develop into one or more specific types of cells in the body. These cells include neurons, blood cells, skin cells, muscle cells, and many others. This process involves two major steps: differentiation and specialization.
During differentiation, each of the many types of cells in the body has to be developed separately. For example, skin cells have to differentiate into hair follicles, sweat glands, sebaceous glands, and so on. The developing brain cells must differentiate into a specific set of brain cells (neurons) that make up the cerebral cortex. During specialization, each of these specialized cells becomes specialized for its specific function. For example, skin cells specialize to form keratinocytes, which form the outer layer of our skin. Neurons specialize to make connections with other neurons in the brain. Blood cells specialize to carry oxygen throughout the body.
The process of differentiation and specialization is continuous, as new cells are constantly being created and old ones are constantly dying off. This continuous process of change is what allows the body to grow and develop throughout life.

lipoproteins that are primarily sent to skeletal muscles and adipose tissues are called
Lipoproteins primarily sent to skeletal muscles and adipose tissues are called Very Low-Density Lipoproteins (VLDL).
Lipoproteins that are primarily sent to skeletal muscles and adipose tissues are called low-density lipoproteins (LDL). LDL is often referred to as "bad cholesterol" because if levels become too high, it can increase the risk of developing cardiovascular disease.
LDL particles are smaller and denser than other lipoproteins, and they can easily penetrate the arterial wall and build up as plaque, leading to atherosclerosis. It is recommended that individuals maintain their LDL levels below 130 mg/dL, although an ideal level is below 100 mg/dL. This can be achieved through lifestyle modifications such as a healthy diet, regular exercise, and medication if necessary. In summary, the long answer to your question is that lipoproteins sent to skeletal muscles and adipose tissues are called LDL, and high levels of LDL can increase the risk of cardiovascular disease.

How can a shortage of nutrients harm organisms in an ecosystem? How can an excess of nutrients harm organisms in an ecosystem? Give an example of each scenario to support your answers.
Answer:
Explanation:
Shortage of nutrients in an ecosstem can harm an organism because when nutrients are scarse or very limited for organism and did not meet up with the organism requirements, there will be reduced metabolism and this can cause malfunction. Shortage of nutrients can lead to decline in growth and can lead to spring up of some diseases in the organism because enough nutrients us not available for good metabolic processes and fight diseases.
For example when an organism is deficient in vitamins and carbohydrates, the organism will not have energy to power metabolic processes and for it's activities and vitamins deficient will make the organism not to have the ability to fight against disease.
Too much of nutrients also affect organisms negatively. When there is much build up of nutrients, it can be harmful to the organisms and restrict metabolic processes.
For example too much of nutriwnts like too much of fat can block blood artieries and veins and thus can lead to inability of blood to flow .

The eukaryotic mitochondrial dismutase is most similar to the E. coli dismutase with manganese as they share the highest number of similar amino acid sequences, 21.
How does the amino acid data support the endosymbiotic theory?The amino acid data provided support the endosymbiotic theory as it shows that the mitochondria of eukaryotes were once free-living bacteria.
c. To calculate the allele frequencies for the eukaryotic mitochondrial dismutase MnSOD we can use the following formula: allele frequency = (2 x number of homozygotes) + (number of heterozygotes) / (2 x total number of individuals).
For the 1985 population:
A allele frequency = (2 x 72) + 221 / (2 x 475) = 0.35
V allele frequency = (2 x 182) + 221 / (2 x 475) = 0.65
For the 2015 population:
A allele frequency = (2 x 98) + 235 / (2 x 512) = 0.34
V allele frequency = (2 x 179) + 235 / (2 x 512) = 0.66
We can compare the A allele frequency between the two populations to see if there was a change.
It appears that the A allele frequency slightly decreased from 0.35 to 0.34 over the 30-year period, while the V allele frequency slightly increased from 0.65 to 0.66.
