Answer:
b.
Explanation:
Based on the information provided within the question it can be said that from this info the researcher can conclude that Dandelion seed number is a constitutive defensive response to rabbit herbivory. This is mainly due to the fact that Dandelions that have been eaten by the rabbits have produced more seeds, meaning that the Dandelions defense mechanism produces more seeds when attacked in order to prevent the flower's extinction.
Answer: C. Cancer
Explanation:
Current cancer immunotherapies mainly focus on CD8+ T cells. Given the heterogeneous nature of cancer, personalized cancer immunotherapy that integrates the power of both CD8+ T cells in adaptive immunity and NK cells in innate immunity might be the future direction, along with precision targeting and effective delivery of tumor-specific, memory CD8+ T cells and NK cells.
Step 1: Imbibition water fills the seed.
Step 2: The water activates enzymes that begin the plant's growth.
Step 3: The seed grows a root to access water underground.
Step 4: The seed grows shoots that grow towards the sun.
Step 5: The shoots grow leaves and begin photmorphogenesis.
<u>Answer</u>: D. calcium chloride
<em>Calcium chloride molecules can be ruled out as the mystery molecule</em>
<u>Explanation:</u>
<em>Artificial membranes are also called as the synthetic membranes.</em> It is created synthetically for the <em>special separation purpose in the laboratory. </em>
It is used to separate large molecules like <em>solid particles and big biological molecules like protein, DNA. </em>
They are produced from organic materials. <em>Calcium chloride contains the chloride ion and calcium ion,</em> as the chloride ion easily passes the artificial membrane so we can term <em>calcium chloride as the mystery membrane that passes the artificial membrane easily.</em>
Answer:
The correct answer is - eliminates all lymphocytes that have been built that would bind and kill healthy, unaffected body cells.
Explanation:
Self-testing in the immune system is a very important step as it helps in analyzing if the immune cells or lymphocytes. To fight against the intruders, the immune system should initially recognize them. That is, the immune system must have the option to recognize what is nonself (remote) based on what is self. The immune system can make this identification since all cells have distinguishing recognition molecules (antigens) on their surface.
Self-test helps in identifying and eliminate in all lymphocytes that have built and attack the healthy cells and killing them.
