Explanation:
The table lists traits and whether they arerecessive or not for two parents. Based on thedata table, if the parents reproduce and create anoffspring, the offspring will-A. definitely have red hair and most likelyhave brown eyes.B. most likely have brown hair and definitelynot have blue eyes.C. most likely have brown hair and definitelynot have blue eyes.D. most likely have red hair and maybe haveblue eyes.
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.
What was the chemical cycle on the prairie like?
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.

Explain the steps in the formation of sedimentary rock.
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

At which concentration of NAHCO3 is the rate of Photosynthesis at its optimum?
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.

What is bacteria?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.
What are the Characteristics of Bacteria?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.

An ecosystem experiences a severe wildfire that wipes out all plant and animal life.Which sentence is true?A. Only abiotic factors were destroyed by the wildfire, but even if the biotic factors remain the same, the ecosystem can never return to stability.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.c. Only abiotic factors were destroyed by the wildfire, so if the biotic factors remain the same, the ecosystem can 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.
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.

List at least 3 natural causes of deforestationList at least 3 human causes of deforestation.
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.

Why cant plants and animals cant use nitrogen as it is in the atmosphere?
The most abundant naturally occurring gas in the atmosphere is the Nitrogen (N2); however, plants and animals are unable to use this directly because of their inability to break down its triple bond. In order for them to utilize this gas, it must be transformed into another form or molecules. There are ways where to convert nitrogen to make it useful for the plants and animals.
The first one is lightning. At the time when lightning strikes, nitrogen gas is transformed into nitrates by which plants can use.
The second one is through the process of nitrogen fixation. In this process, special nitrogen-fixing bacteria helps in converting this gas into useful forms.
Lastly, when there is a decaying organism. Nitrogen is released in the form of ammonium.
