Taphonomists would probably conclude that hominins had scavenged meat from an animal carcass, they did not kill if fossil animal bones; did not contain stone cut marks, which are easily distinguishable from tooth marks.
Some characteristics that have distinguished hominins from other primates, living and extinct are their erect posture, bipedal locomotion, larger brains, and behavioral characteristics such as specialized tool use, and in some cases communication through language.<span />

Under a microscope, the cells of the mushroom plants and animals all have visible nucleus. This makes them all:

KATRIN_1 [288]

The correct answer is B -Eukaryotes.

“Eukaryotes are the organisms that possess a true nucleus (containing the DNA, which is the genetic material) and the membrane bound subcellular compartments ( also known as cell organelles) such as golgi complex, endoplasmic reticulum, mitochondria.
As per the given information in the question, cells of mushrooms, plants, and animals all have visible nuclei under a microscope.
Thus, it indicates that these organisms are eukaryotes.”

To efficiently provide the ideal amount of nitrogen fertilizer, some farmers make use of a "chlorophyll meter" that measures the

NikAS [45]

Answer:

Chlorophyll is a green pigment found in chloroplast in plants. It absorbs sunlight during the process of photosynthesis. It is a chelate molecule. In a chelate molecule a central metal ion forms bonds with a large organic molecule made of carbon, hydrogen and other elements like nitrogen or oxygen.

In chlorophyll, magnesium is the central metal ion and it is bonded to a large organic molecule called as porphyrin. Porphyrin constitutes four nitrogen atoms to which the central magnesium is bonded in square planar arrangement. Since chlorophyll is responsible for the green color of the leaves, more the green color more the chlorophyll content and more is the nitrogen content. Hence, chlorophyll meter measures this green light and finds out if the plant needs more or less nitrogen.

Maggie's Plant Experiment In this exercise you will read the following scenario and identify the parts of the scientific method

ANTONII [103]

Answer:

Please find the identified steps of the scientific method below

Explanation:

A scientific method is a series of steps that aims at solving a problem. The steps in a scientific method include:

1. Making observation: In this experiment, Maggie observed when she read that some plants grow better if the soil is acidic. This is her observation that led to the scientific question: Do plants grow better in an acidic soil?

2. Formulating hypothesis: Hypothesis is a testable explanation to a problem. In this experiment, Maggie's hypothesis is; IF acid is added to the soil, THEN plants will grow better

3. Test hypothesis: the hypothesis is tested by conducting an experiment. In this case, Maggie places two geranium plants of the same size in two pots. Then she added a tablespoon of vinegar to one of the pots and allows the other grow normally without acid. The independent variable in this experiment is the vinegar added while the dependent variable is the height of the plants. The plant group with the vinegar is the experimental group while the plant group without vinegar is the control group. The constants of this experiment are same sunlight, same amount of water, same location etc.

4. Analyse data: The growth of the control and experimental plants were measured every week for five weeks by measuring their heights. The height (cm) of the plants with vinegar for the five weeks as as follows: 10.0, 12.4, 14.8, 18.0, 21.4 while the height in cm for the plants without vinegar for the five weeks is as follows: 10.0, 11.5, 13.0, 15.7, 17.8.

5. Conclusion: Based on the result, the plants exposed to vinegar grew better each week except week 1, which is the week they started. Hence, the hypothesis of this experiment will be ACCEPTED because the experiment proves it.
