Answer:
The answer is C- Lysosomes are present in both bacterial and animal cells.
Explanation:
Lysosomes contain digestive enzymes inside them, which when released break down damaged cell parts. These enzymes are <em>acidic</em> in nature and are separated from other organelles with the help of a membrane.
Lysosomes help in<em> killing bacteria and virus</em> invading the cell body. Lysosomes also take part in the process of cell death known as '<em>apoptosis</em>'. This happens only when a certain cell is beyond repair.
Lysosomes are present in plant cells, animal cells, bacterial and yeast cells.
Hypothesis: The soil in the flat part of the field has less fertility than the soil on the small hill.
Experiment:
The experiment will be carried out in a greenhouse, to promote a controlled environment and equal to all plants used in the treatment.
In this experiment, the influence of the difference in fertility of the soil samples, in the flat part of the land and in the most inclined part, in the germination and growth of corn plants will be tested.
Corn seeds of the same species will be selected. All seeds will be sanitized and will go through the same dormancy breaking process, so that all of them have their germination stimulated.
Vessels with a capacity of 30 kilos will be caught. These pots will be cleaned, sterilized and filled with the same amount of soil collected in the field and with two corn seeds. It will be used 10 pots with soil that was collected in the flat part of the land, 10 pots with soil from the sloping part of the land and 10 pots with fertilized substrate containing high levels of fertility.
The pots will be placed in a greenhouse and will be irrigated with distilled water, to avoid contamination by possible substances in the water.
The pots will remain in the greenhouse for 100 days, where the behavior of seeds and plants in each of them will be observed and noted. After this period, a comparison will be made between the vessels of each treatment, assessing the differences between them and reaching the conclusion whether the hypothesis is true or false.
<span>Hydrogen chemolithotrophs are almost all facultative chemolithotrophs; the sulfur
chemolithotrophs and nitrifying bacteria are nearly all obligate chemolithotrophs.</span>
This occurs through the process of cell specialization, where in some cells genes are active whereas in others they are not.
Answer: Some mutations have a positive effect on the organism in which they occur. They are called beneficial mutations. They lead to new versions of proteins that help organisms adapt to changes in their environment. ... The mutations lead to antibiotic-resistant strains of bacteria. brainliest?
