B) All invertebrates are chordates; vertebrates are a group that is separate from both invertebrates and chordates.
C) All invertebrates are chordates; vertebrates are a group that is separate from both invertebrates and chordates.
D) Chordates are the largest group, and it is subdivided into two groups: vertebrates and invertebrates.
Answer:
The most appropriate answer would be option A.
The chordates refer to the organisms which belong to the phylum Chordata. They possess anatomical features like notochord, pharyngeal slits, dorsal nerve cord, post-anel tail, and endostyle during some period of their life cycle. They include classes amphibians, fish, reptiles, birds, and mammals. These organisms are believed to share a common ancestor.
In contrast, invertebrates refer to the organisms which lack a vertebral column. They include all the organisms other than vertebrates. For example, they include arthropods, mollusks, annelids, and cnidarians.
Answer:
Supine with the backboard tilted to the left.
Explanation:
Pregnancy period is also known as gestation period, the development of the offspring inside the womb. The pregnancy is divided into the different trimester periods.
A pregnant female has fallen down a flight of steps. The lady should be supine with the back board must be tilted to the left as this position reduces her dizziness. This position helps the female to relax and provide protection to both the mother and the offspring. More oxygen will be available to the female.
Thus, the correct answer is option (c).
The correct answer is option A
Auxin promotes cell elongation and cell division in stems. They promote stem elongation and inhibits the growth of lateral buds.
This plant hormone is produced in the stem tip and then it travels to the darker side of the plant so that the cells in the darker side grows more than the cells in the lighter side of the plant.

The gray tree frogs are adapted to the trees of the woodlands, while the green tree frogs can survive in woodlands or grasslands. The gray frog was abundant in the woodlands. Because of climatic changes, most of the trees in the region died, and the woodlands changed to grasslands. In such a case, the
.
The gray tree frog is closely related to the green tree frog genetically, but they have different mating calls. This suggests that speciation occurred because of
.
Answer:
the speciation of the gray tree frog and the green tree frog in the given scenario is likely a result of natural selection caused by the change in habitat from woodlands to grasslands, leading to differences in their mating calls.
Explanation:
the change in the environment from woodlands to grasslands due to climatic changes led to speciation, resulting in the gray tree frog and the green tree frog having different mating calls. This suggests that speciation occurred because of natural selection.
Here's an explanation of how this process might have occurred:
1. Initially, both the gray tree frog and the green tree frog shared a common ancestor and had similar mating calls.
2. When the climatic changes caused most of the trees in the region to die, the woodlands transformed into grasslands.
3. This change in habitat created a new selective pressure on the tree frogs. The gray tree frogs, which were adapted to the trees in the woodlands, faced difficulties surviving in the new grassland environment.
4. However, the green tree frogs, which had a broader habitat range and could survive in both woodlands and grasslands, were better suited to the new environment.
5. Over time, the gray tree frog population in the grasslands declined, while the green tree frog population thrived.
6. As the populations became isolated from each other, natural selection acted on the genetic variations present within each population.
7. The different mating calls between the gray tree frog and the green tree frog might have developed as a result of sexual selection. Frogs with mating calls that were most attractive or effective in their respective environments were more likely to reproduce and pass on their genetic traits.
8. Eventually, the genetic differences between the gray tree frog and the green tree frog became significant enough that they were considered separate species
