Explanation

Natural resistance refers to an organism's inherent ability to resist diseases or pests due to genetic factors.

Explanation

The lineage of reptiles that includes dinosaurs is now extinct.

Dinosaurs were a diverse group of reptiles that dominated terrestrial ecosystems during the Mesozoic Era.

They went extinct around 66 million years ago at the end of the Cretaceous Period

Explanation

 A healthy heart beats around 72 times per minute, which translates to roughly 100,000 beats per day. 

Explanation

The final step of the scientific method is developing a conclusion.

It involves summarizing the findings, interpreting the data, and determining whether the hypothesis was supported or rejected.

The scientific method steps in order:

• Observation
• Hypothesis
• Prediction
• Research
• Experimentation
• Data Analysis
• Conclusion

Explanation

Crocodilians are thecodont. Thecodont is a type of dentition where teeth are set in sockets in the jawbone. 

Explanation

A dermatologist is a medical doctor who specializes in conditions that affect the skin, hair, and nails.

Explanation

Divergent evolution occurs when two species that share a common ancestor evolve different traits or characteristics over time due to adapting to different environments or ecological niches.

This process leads to increased differences between the species.

Explanation

Capacitation is the physiological process that sperm must undergo to gain the ability to penetrate and fertilize an egg.

This process occurs after the sperm enters the female reproductive tract

They involve a series of biochemical changes that enhance the sperm's motility, and its ability to bind to the egg.

It is distinct from spermiogenesis (the final stage of sperm development), the acrosome reaction (which occurs later during fertilization), and fertilization itself

Explanation

Crocodiles have homodont teeth, meaning all their teeth are similar in shape and function.

Homodont teeth are uniform and do not differ in type like incisors, canines, or molars.

Explanation

When a homozygous dominant individual mates with a homozygous recessive individual,

their offspring will all be heterozygous for that particular trait.

This results in a genotype of heterozygous (Aa) for all offspring.

Since the dominant allele masks the effect of the recessive allele, the phenotype of the F1 generation will exhibit the dominant trait.
