How are government agencies like the local health department working to keep the public safe from the problem of HAB's?
Answer:
The local health departments work together with local water suppliers and act to monitor harmful algal blooms (HABs)
Explanation:
Harmful algal blooms (HABs) are produced by blooms of algae (phytoplankton), some of them may produce toxins that lead to illness/death in humans and marine organisms (e.g., marine mammals, fish, seabirds, etc). HABs represent a real concern for coastal areas. Cyanobacteria, also known as blue-green algae, may produce HABs both in fresh water and in marine water. Some of the most common causes that may lead to a HAB include the runoff of nutrients (especially those rich in nitrogen and phosphorus), high temperatures, a slow movement of water bodies, etc. The local health departments work to monitor these phenomena by collecting samples in order to analyze the state of the water (i.e., by identifying the presence of toxins, especially cyanotoxins) and give advice to local residents. For these purposes, it is generally required to analyze phytoplankton composition, especially the presence of accessory pigments to chlorophyll a (since these pigments represent good indicators for possible HABs).
Why do cells continue to divide in adult organisms?
Answer:
Although most of the tissues in adult organisms maintain a constant size, the cells that make up these tissues are constantly turning over. Therefore, in order for a particular tissue to stay the same size, its rates of cell death and cell division must remain in balance.
Explanation:
There are two main reasons why cells divide rather than continuing to grow larger and larger: The larger a cell becomes the more demands the cell places on its DNA. If the cell grows too large, it will have trouble moving enough nutrients and wastes across the cell membrane. Why does cell division remain important to an adult organism even after it is fully developed? It remains important because cells are renewed and wounds are healed in the process. When cells stop dividing to specialize in structure and function. When cells undergo programmed cell death.
The predominant plants found in the savanna are grasses, and there are only a few isolated or small clusters of trees. Which abiotic factor helps to maintain the savanna as a grassland rather than a forest?
A Loose Soil
B Abundant rainfall
C warm temperatures
D lightning Fires
PLEASE HELP
Loose soil is the abiotic factor which helps to maintain the savanna as a grassland rather than a forest. Thus, the correct option is A.
What are abiotic factors?Abiotic factors are those components of the ecosystem which are non-living. Abiotic factors include soil, temperature, rainfall, fire, etc.
Savanna is a biome which contain predominantly grasses with a few isolated or small clusters of trees in the ecosystem. The loose soil in this biome is mainly responsible for maintaining savanna as a grassland rather than a typical forest.
Loose soil is an abiotic factor which is responsible for the forestation of an ecosystem. It is difficult for the big trees to hold the loose soil whereas the grass have their perennating organs protected below the surface of the soil. Thus, they are favored in the savanna biome.
Therefore, the correct option is A.

Explain- C pairs with G and A pairs with T. Vise verse.
The correct answer is A CGT. As repair enzyme would replace them with CGT.
The practical section of DNA is known as genes. Gene is the section of DNA that codes for a practical protein. Genes are inherited from mother and father to offspring. They convey genetic statistics from one technology to another.
What are the 4 bases of DNA?
CGT is an acronym for the 4 forms of bases located in a DNA molecule: adenine (A), cytosine (C), guanine (G), and thymine (T). A DNA molecule includes strands wound around every other, with every strand held collectively through bonds among the bases. Adenine pairs with thymine, and cytosine pairs with guanine.
Hence concluded that CGT is a segment of DNA that has undergone a
mutation in which three nucleotides have been deleted.

Explain how each type of infectious agent (bacteria, virus, fungi, and parasite) affects the body.
Answer:
bacteria-Some bacteria help to digest food, destroy disease-causing cells, and give the body needed vitamins. Bacteria are also used in making healthy foods like yogurt and cheese. But infectious bacteria can make you ill. They reproduce quickly in your body.
Virus-A virus infects your body by entering healthy cells. There, the invader makes copies of itself and multiplies throughout your body. The new coronavirus latches its spiky surface proteins to receptors on healthy cells, especially those in your lungs.
fungi-When fungal organisms enter the body and the immune system is compromised these fungi grow, spread and invade into tissue and spread locally. Some organisms, especially yeast and some molds, can invade the blood vessels and cause infection in the bloodstream and distant organs.
Parasite-When the worms live in the body they can cause sickness. They may get into the stomach and gut and eat the food before the body has digested it. This means that the body does not get enough nourishment. Sometimes the worms will find their way into other parts of the body, such as the blood or liver.

A cell contains the structure shown below that contains chlorophyll and is the site of photosynthesis. What
other cell structure that is not found in all eukaryotic cells, is likely to be found in this cell?
A. Mitochondria
B. Cell Membrane
C. Cell wall
D. Cytoplasm
The cell wall is found in plant cells but is absent in animal cells. Therefore, option C is correct.
What is a cell wall?Cell walls are a specific type of extracellular matrix that covers every plant cell. Many of the traits that set plant cells apart from animal cells are caused by the cell wall.
Plant cells have a cell wall that surrounds their plasma membrane and offers tensile strength as well as defense against osmotic and mechanical stress. Additionally, it enables the development of turgor pressure or the pressure of the contents of the cell against the cell wall.
The pectin polysaccharide matrix, which is highly cross-linked, contains a matrix of cellulose microfibrils and cross-linking glycans that make up the cell wall. Lignin may accumulate in secondary cell walls. Therefore, option C is correct.
