Answer: The mononuclear phagocyte system (MPS), which includes macrophages and dendritic cells, has also been implicated in the regulation of skin salt homeostasis and blood pressure [35]

Explanation:

Answer:

The phagocytes cell in the skin are the monocytes, macrophages, neutrophils, tissue dendritic cells and mast cells. One litre of human blood contains about six billion phagocytes.

When pathogens are detected, the immune system produces millions of white blood cells, which fight the infection. Blood vessels near the wound expand, and white blood cells move from the vessels to enter the infected tissues. Many of these white blood cells are phagocytes which engulf and destroy bacteria.

Explanation:

Gibberellic acid (GA) plays a crucial role in a-amylase production and germination. GA stimulates the synthesis and release of a-amylase enzymes, which hydrolyze starch into sugars during germination. Experimental studies have demonstrated that the application of GA accelerates a-amylase production and enhances germination in various plant species

In terms of a-amylase production, GA stimulates the synthesis and release of this enzyme. a-amylase is responsible for breaking down starch into simpler sugars, which are then utilized by the plant for growth and development.

Studies have shown that applying GA to plant tissues or seeds results in an increased production of a-amylase, facilitating the conversion of stored starch into energy-rich sugars.

Regarding germination, GA is involved in breaking seed dormancy and promoting the growth of the embryonic plant.

It stimulates the production of hydrolytic enzymes like a-amylase, which enable the hydrolysis of starch reserves in the endosperm, providing the energy needed for germination and seedling establishment.

Additionally, GA helps in cell elongation and division, promoting the growth of the embryo and the emergence of the radicle.

Evidence for GA's role in both processes includes studies where the exogenous application of GA to seeds or plant tissues has been shown to enhance a-amylase production and promote germination.

Conversely, inhibiting GA synthesis or action results in reduced a-amylase activity and impaired germination. These findings support the critical involvement of GA in both a-amylase production and germination processes in plants.

Answer: 1. All organisms are made of cells

Cells are the smallest unit of life. Each cell is a membrane of semi-permeable phospholipids wrapped around cytosol or a solution of water and dissolved solutes. All cells rely on DNA to hold the information necessary to produce the molecules they use to obtain energy. Although the methods for obtaining energy vary widely, all organism obtain energy to grow and reproduce. This first tenet of the cell theory is mostly true, but the discovery of viruses lead to complications. Viruses, while they use DNA or RNA to reproduce, do not have cells or cellular membranes. Viruses typically use a host cell to replicate. In this case, the virus appears to be living, but does not create its own cell. Some scientist argue that viruses are not living, thus cell theory is not violated.

2. Cells are the most fundamental unit of life

Organisms can be single cells, which hold all of the components necessary for a metabolism, or they can be more complex. More complex organisms divide the various metabolic tasks into different groups of cells, called tissues. These tissues are arranged in compartments with membranes that separate them from other tissues. These groups of tissues are called organs. A group of organs functioning together is an organism, or an individual creature. Each cell is distinct from the cells next to it, and each functions independently, while contributing to the output of the organism as a whole. Again, modern cell theory is a bit more complicated because advances in science have revealed many different organelles within cells. These organelles are bound in membranes themselves, and serve different functions for eukaryotic cells. Some scientists argue that these are more fundamental units, but other scientists argue that like an organ outside of an organism, they could not function without the cell.

3. Cells come from other cells

As far as we know, no cell on Earth currently has arisen spontaneously. All cells are the result of cell division. When a cell is large enough, it replicates its DNA and important components. These components can then be divided into two daughter cells, which are copies of each other. Variations in the DNA in each cell can lead to changes in how they function, which can result in them dividing at different rates. The cell that reproduces more than the other cell will pass on more of its DNA. The purpose of every cell or organism is to reproduce the DNA in cells.

This third tenet of the cell theory has yet to be disproven. No scientist has ever created a functioning cell without replicating another cell, although some scientists are trying. If they were successful, it would give proof to how life could have evolved. It is thought that a self-replicating molecule mutated, developed the ability to produce a membrane, and thus the first cell was born. The cell was such a successful form of life that all life since has used the same basic template.

Answer: a violation of privacy

Explanation:

A person's DNA cannot be changed as it is their genetic information. It is therefore their most private information and when it is utilized in forensic DNA testing, it runs the risk of invading a person's privacy.

Forensic DNA testing works by comparing the subject DNA with a DNA database. Using this database means going through the DNA of millions of people without their consent.

This is their most private information and it is being stored and accessed without permission. Critics say that this is a violation of privacy and many studies have showed that this is a major concern

Heterozygous individuals are those who carry a dominant and a recessive allele in their genotype. Question 6 is true, Heterozygous individuals will display the dominant trait but carry the recessive allele that can be passed to future offspring.

When talking about heterozygous or homozygous individuals, we are referring to their genotype.

The heterozygous individual carries two types of alleles. Depending on the inheritance pattern and the interaction between alleles, one of them can dominate over the other one, can be equally dominant, or is incompletely dominant.

In the case of complete dominance, the dominant allele completely hides the expression of the recessive allele. So the heterozygous individual will express the dominant phenotype because of the presence of the dominant allele but will carry a recessive allele that will be transmitted to the progeny.

Question 6 is true, Heterozygous individuals will display the dominant trait but carry the recessive allele that can be passed to future offspring.

The introduction of the spiny water flea into the lake is likely to have a negative effect on the balance of the native ecosystem, as the water fleas will compete with native fish for resources such as zooplankton, and may disrupt the existing food chain.

A water flea is an aquatic crustacean. Normally, it is a member of the order Cladocera, meaning it has a small body, two antennae, and a single shell (a carapace) over its back. Water fleas move by using the hair-like setae which are located on their legs. They are an important part of aquatic ecosystems as they are used as food by other aquatic organisms. They also help to clean up organic matter in water bodies, thus improving water quality.

A zooplankton is a microscopic or tiny aquatic animal, usually found in oceans or freshwater bodies. They are usually very small in size and typically feed on phytoplankton. Zooplankton are key components of aquatic food webs and are a vital part of the aquatic environment. They are also important for carbon cycling, filtering pollutant particles from the water, providing food for fish and other aquatic organisms, and providing a food source for larger predators.
