In what conditions can asexual reproduction occur?

Answers

Well, it mainly occurs in microorganisms (bacteria, protists, etc), but also it mainly occurs in the 'real world' when the reproduction need is basically quantity over quality. For example, dandelions spread their seeds via the wind when they get white and fluffy, as it allows the dandelion to spread many many 'offspring' with relative ease. So in short, asexual reproduction can occur in most environments, but asexual reproduction is only found in conditions where quantity over quality is key for survival of a species.

Asexual reproduction takes a variety of forms. The simplest one-celled organisms may reproduce by binary fission, in which the cells simply divide in half. This form of reproduction creates a clone of the parent, and has the benefit of usually being very quick and energy efficient. For example, bacteria that reproduce by binary fission can give rise to progeny every few hours.

Secretes hormones that are stored in the posterior pituitary gland

Answers

Answer:

Hypothalamus

Explanation:

The cell bodies of the neurosecretory cells of the paraventricular and the supraoptic nuclei of the hypothalamus synthesize the hormones oxytocin and antidiuretic hormone (ADH), also called vasopressin. These hormones are stored and released in blood by the posterior pituitary gland. The posterior pituitary does not synthesize hormones.

The hormones from the hypothalamus are packed into vesicles and are transported to the axon terminals of the posterior pituitary via the hypothalamic–hypophyseal tract. The hormones are stored in axon terminals and released in the blood when required.

In the study of cancer, researchers have used different types of cells, different environmental conditions, and different experimental designs. But, all researchers have arrived at the same conclusion. Which conclusion is that?

Answers

Answer:

Cancer is the genetic order than can be caused by different reasons but one of the main is "MUTATION IN GENES"

Cancer is a group of diseases involving abnormal cell growth with the potential to invade or spread to other parts of the body. These contrast with benign tumors, which do not spread to other parts of the body.
cancer cells lack contact inhibition meaning meaning that in normal cells when they come in to contact with other cells they stop reproducing only cancer cells do not. They just keep reproducing and growing destroying everything in their path. An example of this is a tumor.

The principle stating stating that the oldest rocks occur on the bottom of an undisturbed rock sequence is known as

Answers

The principle of Superposition states that, in an undisturbed sequence, the oldest rocks are at the bottom of the sequence and successive layers are younger than those below them. This is different from relative dating because, relative dating examines rock position in aq sequence to determine the order of events the rock's relative age.
