Answer:
Soil Erosion
Explanation:
Basically, tillage breaks soil up, destroying its overall structure. It encourages surface runoff and therefore soil erodes more easily. In some cases soil erosion is beneficial, but in most cases, it is not. Tillage has also been found to cause the emissions of more toxic gases such as N20.
Answer:
large central vacuole
cell wall
Explanation:
Let me clear some things up for you. There are two types of cells - Prokaryotes and Eukaryotes. The principle difference between these types of cells are the structure of their genome. In case of prokaryotes, the genomic matter do not have a defined structure, it just kind of floats around in the protoplasm. But in the eukaryotes, the genome is more structured, have all kinds of proteins associated with them, and is surrounded by a two layered sack called the nuclear membrane. Both plant and animal cells have these feature of structured nucleus, therefore, they are both eukaryotes.
Now for the difference between plant and animal cells. the features you mentioned are unique about plant cells, but do not rule them out from being eukaryotes, as the 'true' structure of the nucleus is still there. Cell walls are necessary for the plant cells because plants do not posses an endoskeleton like most of the animals do. The cell wall makes the whole plant rigid so they don't fall apart or appear like a blob. Chloroplast is where photosynthesis happens, so it should most definitely be in a plant cell. Animals don't do photosynthesis so they don't have chloroplasts. Vacuoles are also present in animal cells, but they are much smaller, greater in number, and are known as lysosomes. Functionally they are virtually the same.
Answer:
The probability of obtaining a "goober" butterfly is 6.25%
Explanation
If there are three possible combinations of butterflies, with yellow and blue being dominant, green is supposed to contain a recessive pattern, so according to Mendel's law of character independence, the pattern RR and BB manifest the dominant phenotype yellow, blue or yellow and blue in spots, the green pattern must be recessive is represented by the letter a, the punnett graph is made, obtaining that 56% present a dominant pattern, 37.5% will be spotted and the pattern recessive must match to generate 6.25% of butterflies “goober”.
Answer:
D
Explanation:
because molecule A is only shown on the outside and is not exposed to the acidity on the inside of the cells
