The double helix is a description of the molecular shape of a double-stranded DNA molecule. In 1953, Francis Crick and James Watson first described the molecular structure of DNA, which they called a "double helix," in the journal Nature.
Answer:
Liquids have an indefinite shape, while solids have a definite shape.
Answer:
A. These homologous structures indicate that these four organisms all share a common ancestor.
Explanation:
Homologous structures mean the organs will have similar structure, but not necessarily function (human arm vs whale's flipper). While analogous structures are similar in function but not structure (wings of an airplane vs wings of a bird). Since the question states that they are similar in skeletal structure, we know they must be homologous structures, thereby eliminating B and C. D is not a choice because the question does not provide anything about the order of evolution. Therefore the answer is A. These homologous structures indicate that these four organisms all share a common ancestor.
Habitat: Coyotes are able to easily adapt to different habitats. They can be found living anywhere from the Sonoran Desert to large, populated cities.
Food: Coyotes will eat nearly anything. They hunt rabbits, rodents, frogs, fish, and even deer. they also eat insects, snakes, fruit, and grass.
Reproductive Process: Reproduction<span> in the </span>coyote<span> is a very intricate </span>process<span>, as females are completely infertile for ten months out of the year, and males are sterile for eight. The </span>process<span> begins with several males vying for the attention of a single female.</span> In spring, females den and give birth to litters of three to twelve pups. Both parents feed and protect their young and their territory.
Human and Environmental Challenges: Coyotes face many challenges. They are often hunted by other larger animals. Humans also hunt them when they are interfering with their crops or livestock.
Migration pattern: <span>According to a study, coyotes migrated eastward via two main route: one that went through the northern United States, and one that went through the south. Oddly enough, the Northern and Southern coyotes seemed to meet midway</span>
The answer is c because if you treat the sewage water than you that means that the water will be clean so it prevents diseases
