A highly diversified gene pool could provide a species with a better chance of surviving a drastic environmental change. So, the correct option is B.
What is Diversified Gene pool?Greater genetic diversity within a population is made possible by a diverse gene pool, which raises the possibility that at least some members of the population will exhibit features that are more adapted to the new environment.
This variety can develop as a result of gene flow from other populations or mutations. The number of people having the recessive trait or a limited population size, however, would not always give an advantage in enduring environmental change. A species may have a better chance of surviving a severe environmental shift if its gene pool is extremely varied.
Therefore, the correct option is B.

a. sleep b. breathing c. memory d. pain transmission
Answer:
c. memory
Explanation:
Memory is not a function of the reticular formation. Sleeping, breathing, and pain transmission all are the functions of reticular formation. Thus, the correct option is C.
What is reticular formation?
Reticular formation is a part of the pons region of brain which controls the sleep-wake cycle and also filters stimuli to separate out relevant background stimuli from irrelevant ones.
Reticular formation is one of the phylogenetically earliest parts of the brain and it is crucial for controlling some fundamental processes such as sleeping, breathing, and pain transmission.
The reticular formation is an essential process for the numerous activities of the brainstem. It is located strategically amid the significant nuclei in the brain cells and the nerve fibers that traverse it. The reticular formation looks like an intricate web network.
Therefore, the correct option is C.

The correct options are;
Mammals and turtles are more closely related than are lungfishes and sharks.
Descendants of organism (d) have legs.
Rays and frogs have a vertebral column.
-Birds and ray-finned fishes have a notochord and jaws
Explanation:
This is because phylogenetic tree is a branching diagram that entails different evolutionary relationships that occur between organisms or biological species having common decent or ancestors and showing similar and differences in their genetic characteristics or traits. It shows how species evolved from their ancestors.

In your response include why slight changes in pH are significant to living things.
Answer:
pH: Each enzyme has an optimum pH range. Changing the pH outside of this range will slow enzyme activity. Extreme pH values can cause enzymes to denature. Enzyme concentration: Increasing enzyme concentration will speed up the reaction, as long as there is substrate available to bind to.

Explanation:
Many tree frog populations are threatened due to habitat loss. In an effort to promote conservation, tree frogs may be bred in captivity. A zoo acquired male and female tree frogs from two different populations. In the zoo, the tree frogs were able to successfully mate within their own population, but breeding attempts between the two populations were unsuccessful. Based on this information, which statement correctly describes the relationship between the two populations of tree frogs?
this is for biology test pleasee someone help
Answer: Same Genus but different species
Explanation: took the test and came back
The statement which correctly describes the relationship between the two populations of tree frogs is same genus but different species.
What are the characteristics of genus?A genus is a class or group of something. In biology, it's a taxonomic group covering more than one species. This is a term used by biologists to classify more than one species under a larger umbrella.
A species is defined as a group of organisms made up of similar individuals capable of interbreeding or exchanging genes. Genus: A genus is a taxonomic classification that includes closely related species.
Genus is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family.

Which of the following is not one of Mendel's Laws?
a) Law of Conservation of Mass
b) Law of Segregation
c) Law of Dominance
d) Law of Independent Assortment
Answer:
A
Explanation:
Law of conservation of mass was discovered by Lavoisier
Law of Conservation of Mass is not one of Mendel's Laws. Therefore, the correct option is A.
What are Mendel's Laws?Gregor Mendel's research with pea plants in the 19th century led him to reveal three fundamental laws of inheritance, known as Mendel's laws. There are three laws:
1. Law of Segregation: Each individual has two alleles for each trait, and this law indicates that these alleles separate (separate) during the development of gametes, or reproductive cells. This indicates that only one allele per trait is present in each gamete.
2. According to the law of independent assortment, the inheritance of one trait is independent of the inheritance of another. In other words, the segregation of alleles for one trait is independent of the segregation of alleles for the other trait.
3. The law of dominance states that when two different alleles are present in an individual, the dominant allele will dominate the recessive allele in terms of expression. Only when both alleles are recessive will the recessive allele be expressed.
Therefore, the correct option is A.
