The right answer is Slime molds are able to move

Mucilaginous mold are characterized because at some stage of their life cycle they form multinucleated aggregates (plasmodia) or multicellular (pseudoplasmodiums) that slide along the ground feeding on decaying plant matter. A few are parasites. They can be found on the ground, on the lawn and in deciduous forests. They are also common in leaf mulch or even in silt that accumulates in gutters. Some are aquatic, freshwater or marine.

The "body" of these Myxomycete consists of a mass of cytoplasm called plasmodium which is surrounded only by a thin membrane; there is no rigid wall like most mushrooms. This is why the plasmode can move by creeping or flowing, that is to say, by amoeboid movements.

Answer:

Antigen: is a a foreign substance or toxin that causes a immune response.

Antibody: it is a blood protein that is produced in response to an antigen.

White blood cell: also called a leukocyte and is a cell that counteracts against antigens.

Specific: If you're talking about the biology definition then it is, of or pertaining to a species.

Pathogen: a virus or bacteria that can cause a disease.

Forestry does not contribute to water pollution. Therefore, option A is correct.

What is water pollution?

Water contamination is the tainting of bodies of water, typically as a result of human activity, which has a detrimental impact on their uses. Aquifers, reservoirs, lakes, rivers, seas, and groundwater are all examples of bodies of water. When contaminants are introduced into these water bodies, water contamination results.

The main causes of water pollution are bacteria, viruses, parasites, insecticides, pharmaceuticals, plastics, feces, radioactive materials, fertilizers, and pesticides. These compounds are frequently invisible contaminants since they do not always alter the color of the water.

Industry and agriculture cause water pollution, while forestry does not. Hence, option A is correct.

Answer:Digestion in ruminant animals is a complex and highly specialized process that allows them to extract nutrients from plant material, such as cellulose and other complex carbohydrates, which are otherwise difficult to break down. Ruminants are a group of mammals that includes cattle, sheep, goats, deer, and giraffes. The key to their unique digestive system is the presence of a specialized stomach with four compartments: the rumen, reticulum, omasum, and abomasum.

Explanation:

Here's a step-by-step description of how digestion occurs in ruminant animals:

Ingestion: Ruminants graze on plant material, primarily grasses and leaves, which they consume as their primary source of food.

Prehension: The food is initially ingested and mixed with saliva in the mouth. This is a mechanical process that breaks down the food into smaller pieces.

Rumen Fermentation: The ingested food then enters the first and largest compartment of the stomach, the rumen. In the rumen, microorganisms, including bacteria, protozoa, and fungi, break down cellulose and other complex carbohydrates present in the plant material. This fermentation process produces volatile fatty acids and other byproducts.

Regurgitation and Re-chewing: After some time, the partially digested food is regurgitated back into the mouth in the form of a cud. Ruminants then re-chew the cud to further break down the food particles and mix it with more saliva. This process is known as rumination.

Passage to the Other Compartments: Once the food is adequately broken down and fermented in the rumen, it is passed on to the reticulum, omasum, and finally to the abomasum (true stomach) in sequence.

Omasum: The omasum is responsible for reducing the size of the food particles and absorbing some of the water from the digesta.

Abomasum: The abomasum is the equivalent of a monogastric (single-chambered stomach) like that of non-ruminant animals. Here, gastric juices and digestive enzymes are secreted to further break down proteins and other substances.

Absorption: The small intestine follows the abomasum, where most of the nutrient absorption takes place. This includes the absorption of sugars, amino acids, and fatty acids.

Further Digestion: Any remaining indigestible materials, such as cellulose, continue to be broken down by microbial fermentation in the cecum and colon.

Excretion: Finally, waste products are eliminated from the body through the rectum and anus.

The process of fermentation in the rumen and other compartments is crucial in extracting energy and nutrients from plant material, which would be indigestible to non-ruminant animals. Ruminants have evolved this unique digestive system to efficiently utilize fibrous plant materials as their primary food source.
