Multiple methods of reproduction support the longevity of sponges in the fossil record is described below.

Explanation:

Sponges are able to reproduce both sexually using gametes and asexually by budding. Even though sponges are hermaphroditic, individuals will only make one type of gamete at a time. There are two forms of asexual reproduction that sponges can go through: external budding and internal budding.

Sponges reproduce sexually, too. Sponges do not have separate sexes-a single sponge forms eggs at one time of the year and sperm at a different time. At any one time of the year, some sponges are producing eggs and others are producing sperm.

The volume of water passing through a sponge can be enormous, up to 20,000 times its volume in a single 24 hour period.

Sponges reproduce by both asexual and sexual means. Most poriferans that reproduce by sexual means are hermaphroditic and produce eggs and sperm at different times. Sperm are frequently "broadcast" into the water column. ... Some sponges release their larvae, where others retain them for some time.

Answer:

catalyze chemical reactions

Explanation:

An enzyme is a proteinous substance that acts as biological catalysts and increases the rate of biochemical reactions in the body. Enzymes are specific in nature which is as a result of the structure/shape of its building block (amino acid).

Enzymes speedens the rate of a chemical reaction in living systems, which would normally not occur or occur at a much slower rate, without the presence of an enzyme. Enzymes acts on the reactants called Substrates by binding to them to form products but they are not used up in the reaction. Hence, enzymes are not reactants.

Which of the following best summarizes how hormone levels are controlled?
anastassius [24]

Answer:

Option A, Hormones are controlled by a feedback loop; information about a system is sent back to the controller of the system to improve its function.

Explanation:

Negative feedback loop controls the hormone production and release. This is done by eliciting the release of substances till a certain level after which the stop signal is activated thereby preventing further release. By this method,  concentration of hormones in blood is maintained within the narrow range.  

For example – Thyroid hormones is released when the anterior pituitary signals the thyroid. This continues till the hormones in the blood reach the threshold level. Once the threshold level is reached, hypothalamus receives a feedback and then signals anterior pituitary to inhibit further signaling to the thyroid

Hence, option A is correct
