A food which has been grown without the use of some but not all synthetic pesticides, synthetic fertilizers, or bio engineering could be labeled--- True
What are organic foods ?
-Organic food is produced without using most conventional pesticides, fertilizers made with synthetic ingredients, antibiotics, or growth hormones
When a food is labeled as organic this means that no pesticides have been used in its production?
Produce can be called organic if it's certified to have grown on soil that had no prohibited substances applied for three years prior to harvest. Prohibited substances include most synthetic fertilizers and pesticides.
Are organic food safer?
According to USDA data, organic foods have fewer pesticide residues than conventionally grown produce. But the amounts for both types of produce are within the level for safe consumption.
What is the meaning of organic farming?

The greenhouse effect occurs when rays enter our atmosphere and are reflected from the ground up. They get changed during their voyage through our atmosphere and they change in such a way that they can't leave the atmosphere anymore. Then they stay inside and heat up the planet which causes thing like global warming. That's what the greenhouse effect is.
→ Darwin believed that the need to adapt, in similar words, the changes occruing in the environment caused evolution.
The main cause of evolution, according to Darwin, was natural selection. Natural selection is a process in which a group of organisms with certain characteristics survive and thrive, in comparison to other organisms with different characteristics. This idea basically means that having some characteristics makes you suited for an environment.
And how would that ↑ explain Evolution?
Well, evolution is the change in species that occurs during time. But for you to change, there must be a cause for that change, which is none other than the need to survive, reproduce, etc.
→ As mentioned before, not all characteristics are enough to surive, and hopefully the image pasted below will help you.

Answer:
the answer is all of the above
Answer:
Mollusca Phylum
Gastropoda class
Explanation:
The Mollusca Phylum is one of the most noticeable phyla that includes a wide variety of forms.
The ancestral Mollusca used to habit the pre-cambric oceans. It was bilaterally symmetrical, with a well-defined head that had tentacles and ocellus. Its ventral surface was plane and muscular, shaping a reptant foot. The dorsal surface was protected with a convex and oval shell.
The Gastropoda class is the richest class among all mollusks. This class experienced a characteristic torsion in their shell. This twist also involved the visceral mass, the mantle, and the mantle cavity. But by the time that this torsion occurred, the shell had already experienced a turn into a coil shape, which was then followed by its torsion.
The typical gasteropod´s shell is a conical structure composed of several tubular spirals containing the individual´s visceral mass. The biggest spiral ends as an opening from which the head and the food protrude.
