Answer:
Theres no nucleus and what makes it a nucleus is the nuclear membrane. So the answer is the presence of a nuclear membrane.
Explanation:
DNA is divided into functional units called genes. A gene is a segment of DNA that codes for a functional product (mRNA, tRNA, or rRNA). Since the vast majority of genes are transcribed into mRNA and mRNA is subsequently translated into polypeptides or proteins, most genes code for protein synthesis.
They looked and saw Rosalind Franklin's X-ray crystallography which sparked them to think about the double-helix structure, and from there, they played around with cafeteria items (forks and spoons and whatnot) to create a model that finally worked.
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 options for this question are:
- Requires genetic variation
- Results in descent with modification
- Involves differential reproductive success
- All of the above
Answer:
<u><em>The correct option is d) All of the above</em></u>
Explanation:
The theory of natural selection explains that genetic variations occur in organisms of a species. Those organisms which are better adapted to live in an environment are able to survive and pass on their characteristics to their offsprings, hence descent with modification. Through this phenomenon, evolution takes place with the passage of time. Natural selection favours survival of the fittest. Hence, all of the above statements are true.
