Bacteria are common, mostly free-living organisms having an unusual single biological cell. They account for a large chunk of the prokaryotic microbiological kingdom. Bacteria, which are typically a few micrometers long and were some of the first living organisms to appear on Earth, are found in the majority of its habitats. Bacteria are little, single-celled organisms that draw nutrition from their surroundings. In some circumstances, your child or another living thing is that environment. Some bacteria are beneficial to human bodies because they maintain the digestive system functioning properly and prevent the entry of dangerous germs.

The DNA in bacteria, which are prokaryotes without a nuclear envelope, is found suspended inside the cytoplasm. Bacteria are categorized according to their morphology and how they respond to the Gram stain in a laboratory setting. Gram-positive or Gram-negative bacteria can both exist. Gram-negative bacteria have a thin peptidoglycan coating and outer lipid layer, which prevents them from reacting to the Gram stain. Because they lack the outer lipid layer and have a stronger peptidoglycan layer, gram-positive bacteria do stain.

The refractory period is the time in which the cell membrane remains depolarized, that is, it does not react to a second stimulus. It takes place after an excitation of the cell.

The process that can only be carried out byplants in the presence of light-dependent reactions. These reactions convert light energy to chemical energy and is present in the process of photosynthesis. The energy from the sun together with water is being broken down to give rise to ATP and NADPH which are used in light-independent reaction or dark reactions.

Cellular respiration does not use light since it is not dependent on light. Dark reactions are light-independent processes. Homeostasis is the maintenance of the internal environmentr of an organism in order to survive.

Answer the animal dies

Explanation:

Answer: The animals die I hope this is helpful please mark me brainlist if correct then no if wrong

Explanation:

The animals die and the chemical goes into the soil for the plants and when the animals eat the plants the chemicals are passed back to the plants.Prairie plants are especially adept at storing carbon, locking up large amounts in their roots. In fact, prairies store more carbon below ground than a forest stores above! Deep, complex prairie root systems sequester (store) carbon and – with the help of microorganisms – move it to the soil where it stabilizes.

STEPS IN THE FORMATION OF SEDIMENTARY ROCK

Sedimentation starts when rocks get weathered by rains and winds. The eroded sediments will be washed o scarried in the water. Over time, more sediments will pile up in the water and compresses the lower layers. Strata of layers will happen as time passes by. The salt and dissolved ions in the water act as glue to make it into a rock mass. The rock mass formed is now what we call a sedimentary rock. n

If the parents reproduce and create an offspring, the offspring will definitely have red hair and most likely have brown eyes.

This is because both parents have red hair so they must be homozygous for that character, and as the mother has brown eyes, which is dominant, it is more probable that the phenotype will be expressed by their offspring.

Difference found between organic and non organic compound are organic compounds contains carbon atom while most of the inorganic compounds do not have carbon atom in them. Almost all the organic compounds contain the carbon-hydrogen bond in them.

Carbohydrates, lipids and protein are the macromolecules that are the basic structures of life, they are the primary components of many of the cycles that occurs for survival of plant and animals on earth , mainly the carbon cycle that includes the exchange of carbon between plants and animals in photosynthesis and cellular respiration.

Organic compounds are also important because all living organisms  contain carbon.

Human activities

Human activities are one of the main causes of deforestation. Among them we can find the expansion of urban areas, in which natural areas are deforested to build houses or factories for example; we can also list the expansion of agricultural areas, in this case, several hectares of forests are cut down to be replaced with the cultivation of plants for human consumption and finally another huge problem is the illegal logging of trees, which even occurs in protected natural areas.

Natural causes

Among the natural causes, we can find forest fires, which although sometimes are caused by humans, can also occur in times of extreme heat such as the canicular period; we can also list the presence of pests, which infect and kill the trees reducing their population and finally, another natural cause related to the weather could be that a period of drought occurs.

1) Fossils are the preserved remains of traces of organisms from the past so they are very important evidence for evolution. They show extinct organisms that were very different from any now living, it also shows successions of organisms through time. Fossils tell us when organisms lived, they provide evidence for the progression and evolution of life on the earth over millions of years.

Ecology: Ecological succession, ecosystem

The stability of an ecosystem refers to the ability of an ecosystem to return to equilibrium after a perturbation such as a wildfire, for example, the ecosystem was a forest before the wildfire, and then it can return to being a forest after the fire.

If a severe wildfire wipes out all plant and animal life, then the biotic elements of that ecosystem are destroyed, and a secondary succession begins to take place. This not necessarily means that the same species would colonize.

We are between two options that correctly identify the plants and animals as biotic factors:

B. Plants and animals were destroyed by the wildfire, and even if the abiotic factors remain the same, the ecosystem can never return to stability.

D. Plants and animals were destroyed by the wildfire, but if abiotic factors remain the same, the ecosystem can return to stability.

The first colonizers in a secondary succesion are plants such as grass and herbaceous plants, and the kind of plants that can grow in a place depends on the soil characteristics, sunlight, and water supply, i. e. abiotic factors. So, if the abiotic factors remain the same, the ecosystem should be able to return to stability.

This means the right answer would be D. Plants and animals were destroyed by the wildfire, but if abiotic factors remain the same, the ecosystem can return to stability.

As we can see, throughout the experiment, most of the variables, such as sunlight, size or temperature remained constant with NaHCO3 concentration being the only variable that changed.

NaHCO3 provides CO2 in the aquatic environment and therefore stimulates photosynthesis by increasing the average oxygen obtained in the 5 tests.

However, photosynthesis is no longer stimulated after reaching a concentration of 80 g/L NaHCO3.

Therefore, we can expect that at higher concentrations (120, 140, etc.) there is no significant change and therefore, the optimum NaHCO3 concentration would be 80 g/L NaHCO3.

According to the graph, the two factors that characterize biomes are precipitations and temperature.

Blue-green algae is an  important organisms that play different roles in the nitrogen cycle.

Blue-green algae converts nitrogen into organic nitrogen compounds as well as Nitrobacters and other Nitrogen-fixing microbes. They are essential to healthy water bodies as they are responsible for producing oxygen and are a source of food to certain aquatic animals.

Nitrates and ammonia produced in the nitrogen cycle are as a result of nitrogen fixation made by algae and plants that animals eats and incoporate into their body compounds. They are able to convert dinitrogen however unavailable into bioavailable ammonia.
