<em>"No man is an island.” This saying is also true for organisms in an ecosystem. No organism exists in isolation. Individual organisms live together in an ecosystem and depend on one another. In fact, they have many different types of interactions with each other, and many of these interactions are critical for their survival.
</em>
<em>So what do these interactions look like in an ecosystem? One category of interactions describes the different ways organisms obtain their food and energy. Some organisms can make their own food, and other organisms have to get their food by eating other organisms. An organism that must obtain their nutrients by eating (consuming) other organisms is called a consumer, or a heterotroph. While there are a lot of fancy words related to the sciences, one of the great things is that many of them are based on Latin or Greek roots. For example, heterotroph becomes easier to remember when you realize that in Greek, “hetero” means “other” and “troph” means food; in other words, heterotrophs eat other organisms to get their food. They then use the energy and materials in that food to grow, reproduce and carry out all of their life activities. All animals, all fungi, and some kinds of bacteria are heterotrophs and consumers. </em>

DNA replication allows the basic units of heredity found on segments of DNA called genes to be passed from parent to offspring.
Answer: the correct answer is C) The kinetochore-containing fragment would be pulled toward the pole. The two arm fragments would move away from the pole
Explanation:
A kinetochore is a disc-shaped protein structure linked with duplicated chromatids in eukaryotic cells where the spindle fibers link during cell division to pull sister chromatids apart. The kinetochore assembles on the centromere and links the chromosome to microtubule polymers from the mitotic spindle during mitosis and meiosis. Its proteins also help to hold the sister chromatids together and play a role in chromosome editing.
Answer AND Explanation:
Occasionally the zygote fails to move down the oviduct to the uterus but instead gets implanted into the walls of the oviduct where it develops. If the passage of the fertilized ovum is slowed and hatching occurs prior to the ovum reaching the endometrial cavity, the embryo may implant in the fallopian tube. This condition is called ectopic pregnancy. The most common location in the fallopian tube for ectopic pregnancies to occur is the ampulla (70.0%); other locations, such as the isthmus (12.0%), the fimbria (11.1%) and the cornua (2.4%), are less common.
Explanation:when we are hungry.we crave for food and eat.
the stimulus is when we are hungry
the response that come from brain is that order us to eat
the stimulie is internal.
hope this will help
