Answer:
80%
Explanation:
Pollination is the act of transferring pollen grains from the male anther of a flower to the female stigma. The goal of every living organism, including plants, is to create offspring for the next generation. Seeds can only be produced when pollen is transferred between flowers of the same species.
Honeybees pollinate 80 percent of U.S grown crops—products valued at more than $14 billion. Crops that benefit from honeybee pollination include fruits, nuts, vegetables, cotton and other small grains. They also include cover crops, which farmers plant between commercial crops to prevent nutrient runoff and soil erosion and boost soil nutrients.
It’s estimated that there are about 2.4 million honeybee colonies in the U.S. today.
In a single day, one honeybee makes 12 or more trips from its hive, visiting several thousand flowers at a time. On each trip, it confines its visit to one plant species, collecting one kind of pollen. This enables the colony to find and collect food with maximum efficiency, which makes honeybees the most valuable pollinators.
Answer:
what is microscope is a laboratory instrument used to examine objects that are too small to be seen by the naked eye.
FUNCTIONS : The microscope is one of the most important tools used in chemistry and biology. This instrument allows a scientist or doctor to magnify an object to look at it in detail. Many types of microscopes exist, allowing different levels of magnification and producing different types of images
Answer:
B. the similarity in size between the cytosolic ribosomes of prokaryotes and the ribosomes within mitochondria and chloroplasts
Explanation:
Endosymbiosis explains the origin of mitochondria and chloroplast from the prokaryotes that were capable of carrying out aerobic respiration and oxygenic photosynthesis.
These prokaryotes entered the larger cells and eventually lost the ability to survive as individual organisms.
Prokaryotes have 70S ribosomes while eukaryotes have 80S ribosomes. Being semi-autonomous organelles, both mitochondria and chloroplast also have DNA and ribosomes. The ribosomes present in these organelles are of 70S type. This theory is also supported by the presence of circular DNA in bacterial cells and in the mitochondria and chloroplast.
