Answer:
Chemotherapy targets the cell directly; biological therapy tries to help the immune system so it will attack the cancer cells.
Explanation:
Both chemotherapy and biological therapy are approaches used in cancer treatment.
Chemotherapy involves the use of aggressive anti-cancer drugs. It targets cancer cells directly with the goal to destroy them.
Biological therapy, also called immunotherapy, is a type of treatment used in battling diseases by activating or suppressing the immune system. It is also used in cancer treatment. Its goal is to boost the immune system and help it fight against cancer.
They both take place in the nucleus :)
Answer:
Structurally, plant and animal cells are very similar because they are both eukaryotic cells. They both contain membrane-bound organelles such as the nucleus, mitochondria, endoplasmic reticulum, golgi apparatus, lysosomes, and peroxisomes. Both also contain similar membranes, cytosol, and cytoskeletal elements.
Explanation:
Answer: Disinfectant is a chemical formulation which may include biological components used to reduce the population of a microbe from a living or dead surface.
Explanation:
The plant tissue is treated with a disinfectant before culturing it and growing new plants. This is done to remove dirt, dust, foreign particles like pollen, microbes from the plant tissue surface or from plant part. This help in growth of disease free and contamination free plants. The culture can be utilized for different cycles of plant growth as it remains free from any kind of contamination.
Answer and explanation:
To address this question, we could design an experiment where the effect of soil and gravel can be tested independently. One approach is to test this via <u>Completely Random Design (CRD)</u>. Here, the <u>treatments would be assigned to experimental units completely at random</u> and each treatment will be tested in <u>replication</u> (e.g. triplicates).
The treatment levels would be (1) <u>Grass growing in the soil (triplicates)</u> and (2) <u>grass growing in the gravel (triplicates)</u>. There will be total 6 experimental units and they will be placed randomly. The growth parameters of grass would be then tested after growing for a certain period of time, let's say 90 days.
After this period, the <u>grass will be harvested</u> and the <u>biomass, root length and shoot length</u> will be measured. Because each treatment has three replicate, we will have a clear estimation of soil and gravel on plant growth. The standard deviation would help estimate the effect of natural variations in different treatments. However, they would be consistent because of same environment given for the growth.
The <u>independent variables</u> would be "<u>soil and gravel</u>" and <u>dependent</u> variables would be "<u>growth parameters of the grass (plant root and shoot length and biomass)</u>".
