A field biologist who studies the behavior of birds in a rainforest most likely collects data through observation.
Rainforests are the areas with rich diversity of plants as well as animal species. The trees of rainforests are so long, broad and thick that they completely cover the canopy. They are also recognized by highest rainfalls. Rainforests are considered to be the oldest in the in the Earth's ecosystems.
Observation is the act of carefully watching any action or scenario in order to gain information. Observation can be turned into a formal activity when any data is collected through it for educational or experimental purposes.

During Asexual reproduction, in the interior side of Sporangium spores are made by mold and spreading of more mold occurs and Sporangium will be breaking during the time, when the spores are ready for leaving out.
<u>Explanation:</u>
The formation of spores is the asexual reproduction method that occurs in fungi which is a non flowering plant and bacteria. Many number of smaller and tiny spores that are tough, round shaped and microscopic, are produced by parent plants that has the ability to grow into many newer plants in asexual reproduction method only under certain conditions. Multiple number of spores in the sacs of Rhizopus that is called as sporangia. Te structure of these sporangia is like a knob and these are are present at the top of hyphae which is like a thread.
When these sporangia bursts, the spores are scattered by rain, wind or insects and under suitable conditions develop into a new Rhizopus plant, when they fall on a suitable substance like bread. When a break occurs in these sporangia, scattering of these spores occurs and these develop into a new plant under some suitable conditions, when these falls on a substance say for an instance bread.
"Species A and B are more closely related to each other than species Y and Z are to each other" is the one among the following that is <span>most likely true about these species. The correct option among all the options that are given in the question is the second option. I hope the answer has come to your help.</span>
Answer:
a.They evade the normal controls that trigger programmed cell death.
Explanation:
Cancer cells are cells in the body that grow abnormal and uncontrollably. Continuous growth cancer cells results in the development of tumor as well as the ability to invade neighboring tissues.
Unlike normal cells that are controlled (reproduce only when needed) and are more specialized with specific functions, cancer cells are less specialized compared to normal cells and grow abnormally and rapidly. Cancers cells grow out of control, as they evade the normal control and ignore signals that activate apoptosis or programmed cell death which is used by the body system to destroy unwanted cells.
There are guard cells surrounding each stoma that cause them to open or close throughout the life cycle of the plant. This occurs in response to water and ions concentration in the plant cell.
