Q: Living in a large colony requires good communication. ants communicate with chemicals called what? Read this paragraph and choose the correct option from the provided answers: Living in a large colony requires good communication. Ants communicate with chemicals called pheromones . For example, an ant deposits pheromones on the ground as it returns to the nest from a food source. It is marking the path so other ants can find the food. Honeybees communicate by doing a "waggle dance. ". Choices: - alkalides - hormones - peptides - pheromones A:
pheromones

Ques: Q: The mass percentage of a solution component is defined as the ratio of the component's mass to ________? Read this paragraph and choose the correct option from the provided answers: Mass Percentage Earlier in this chapter, we introduced percent composition as a measure of the relative amount of a given element in a compound. Percentages are also commonly used to express the composition of mixtures, including solutions. The mass percentage of a solution component is defined as the ratio of the component's mass to the solution's mass, expressed as a percentage: mass percentage =. Choices: - enough ' s mass - solvent's mass - liquid's mass - solution ' s mass A:
Ans: solution ' s mass

Q: In addition to spiral cleavage, protostomes also undergo which other form of cleavage? Read this paragraph and choose the correct option from the provided answers: There is a second distinction between the types of cleavage in protostomes and deuterostomes. In addition to spiral cleavage, protostomes also undergo determinate cleavage. This means that even at this early stage, the developmental fate of each embryonic cell is already determined. A cell does not have the ability to develop into any cell type. In contrast, deuterostomes undergo indeterminate cleavage, in which cells are not yet pre-determined at this early stage to develop into specific cell types. These cells are referred to as undifferentiated cells. This characteristic of deuterostomes is reflected in the existence of familiar embryonic stem cells, which have the ability to develop into any cell type until their fate is programmed at a later developmental stage. Choices: - straight - diagonal - dispersive - determinate A:
(A).
determinate

Ques:Q: What is a cluster of neuron cell bodies in the pns called? Read this paragraph and choose the correct option from the provided answers: Regardless of the appearance of stained or unstained tissue, the cell bodies of neurons or axons can be located in discrete anatomical structures that need to be named. Those names are specific to whether the structure is central or peripheral. A localized collection of neuron cell bodies in the CNS is referred to as a nucleus. In the PNS, a cluster of neuron cell bodies is referred to as a ganglion. Figure 12.4 indicates how the term nucleus has a few different meanings within anatomy and physiology. It is the center of an atom, where protons and neutrons are found; it is the center of a cell, where the DNA is found; and it is a center of some function in the CNS. There is also a potentially confusing use of the word ganglion (plural = ganglia) that has a historical explanation. In the central nervous system, there is a group of nuclei that are connected together and were once called the basal ganglia before "ganglion" became accepted as a description for a peripheral structure. Some sources refer to this group of nuclei as the "basal nuclei" to avoid confusion. Choices: - groupilion - gangnem - crystals - ganglion A:

Ans:ganglion

Ques:Q: Vertebrates with four limbs are also called what? Read this paragraph and choose the correct option from the provided answers: Amphibians are vertebrates that exist in two worlds. They divide their time between freshwater and terrestrial habitats. They share a number of features with air-breathing lungfish, but they also differ from lungfish in many ways. One way they differ is their appendages. Amphibians are the first true tetrapods, or vertebrates with four limbs. Modern amphibians include frogs, salamanders, and caecilians, as shown Figure below . Choices: - Amphibians - Birds - Mammals - tetrapods A:

Ans:
tetrapods
