How do biologists model changes in a population?
Answer:
When the per capita rate of increase ( r) takes the same positive value regardless of the population size, then we get exponential growth. When the per capita rate of increase ( r) decreases as the population increases towards a maximum limit, then we get logistic growth.

Answer:
C) The waves amplitude
Explanation:
Answer:
The measurement labeled E is the wave's amplitude.
Explanation:
A vertical rise in a wave length is the amplitude of the wave.
The distance between each curve is the wavelength, if it is a long distance than it is slow if it is a short distance than it is fast.
The waves period is the bottom of the wave where no movement is constant.

What is the best way to breed mice?
At what age can female mice breed?
Only answer if you have experience in this subject!
Will give brainiest!
Generally, putting one male with two females in a single cage will increase the chances of breeding. To prevent fighting, it's important that there's only one male in each cage. If you're not sure which mice are male, gently lift them up by the tail and look between their legs. Most mice reach sexual maturity (males and females) at 4-7 weeks of age. Younger mice generally produce smaller litters and therefore are not typically mated until they reach 6-8 weeks, of age. Mice that have been housed alone or in same-sex pairs will usually not breed successfully if they are older than 6-8 months.

Match the characteristics with the phylum. Tongue-shaped structure called radula for grasping food spongin fibers or spicules for support fleshy lobe-like structure called parapodia Porifera arrowRight Molluska arrowRight Annelida
Answer:
A Tongue-shaped structure called radula for grasping food --> MolluscaFleshy lobe-like structure called parapodia --> AnnelidaSpongin fibers or spicules for support ---> PoriferaExplanation:
Radula: This is an organ used in feeding by mollusks. It constitutes a highly developed feeding organ. The radula has is conformed of small teeth-like structures located in rows. Lateral teeth vary in shape and size. The movements of the radula during feeding are complexes acting as a scratcher on the surface to get the food.
Parapodia: These are characteristic lateral appendixes that emerge and extend from each of the body segments of invertebrates such as polychaetes. The typical parapodium is a fleshy prolongation more or less laterally comprised and is composed of a superior branch (notopodium) and an inferior branch (parapodium).
Spicules: Sponges (Poriferous) skeleton is composed of calcium carbonate and siliceous micro-structures called spicules. Their morphology is so varied that it is used in taxonomy for identification and classification.
There are different kinds of spicules:
- Monoaxonic spicule: needle-shaped, straights or curves
- Tetraxonic spicules: they have four prolongations
- Triaxonic or Hexaxonic spicules
- Poliaxonic spicules
Two terms can be applied to any of these spicules kinds:
- Megaspicules: They are elongated and compose the main architecture of the sponge skeleton
- Microspicules: Variable in shape and size, with ancillary functions
Sponges have few predators because of the spicule structures and their high toxicity. Many of them are capable of perforating soft tissues and producing urticant substances.
