Answer: Asexual reproduction
For example, sexual reproduction allows for variation, but gestation usually takes a long time and it requires heavy parental input. Asexual reproduction occurs quickly, but because all of the offspring have the same genetic information, individuals are more susceptible to disease.

Answer:
Gastrovascular Cavity
Explanation:
Hydra is commonly found in freshwater ponds and ditches as solitary organisms, in underside of aquatic leaves and lily pads in cool,clean freshwater pools and streams. It has a *Cylindrical body shape*.
Hydra possesses an internal body cavity, the *Gastrovascular cavity *,lined by gastrodermis and has a single opening,the mouth,which serves as an anus.
The Gastrovascular cavity of Hydra is a site for *digestion and nutrient distribution*,and also serves as anus.
Answer:
The correct order is: 6) Sarcoplasmic reticulum releases calcium ions, 2) Calcium ions bind to troponin, 5) Tropomyosin moves to expose active sites of actin, 4) ATP is split into ADP and P, 1) Myosin head binds to actin, 7) ADP and P released from myosin, 3) Myosin cross-bridges bend, pulling actin toward center of sarcomere.
Explanation:
The ability to contract is an important property of the muscle cells and is fundamental to animals because muscles not only make locomotion possible but are also responsible for the correct functioning of organs (including the heart).
The mechanism behind muscle contraction is the sliding of filaments in a structure called sarcomere, which mostly involves the presence of actin and myosin filaments.
For muscle contraction to happen, there needs to be a <u>stimulus coming from the nerve that innervates said muscle</u>. This stimulus generates the release of <u>calcium ions</u> that will bind to a protein called troponin and will lead to the exposure of the active site of actin so it can bind to the myosin head. <u>This process requires ATP</u>.
Answer:
Due to their being no options (possibly just an incomplete question), I will just give an answer. So for panda bears, if their food sources became unavailable, they would most likely be in danger of becoming extinct.
But one thing is, pandas do have the ability to survive with bamboo.
But since bamboo comprises 99 percent of their food, although they also consume other plants and even meat, I highly doubt they could (whose make the remaining 1 percent ).
Because the gene T1R1 mutated some 4 million years ago, causing them to lose the ability to taste umami, giant pandas have come to rely significantly on bamboo (which is what makes meat tasty for omnivores and carnivores). The availability of bamboo trunks at the time coincided with their purported food source becoming increasingly limited, thus pandas became used to them and began to rely significantly on them, as they do now.

The sarcomere<span> </span><span>is the basic unit of a </span><span>striated muscle and the force of a muscle is directly related to the extension that the sarcomere is under. When a sarcomere is extended from 1.5 micrometres to about 3 micrometres, the muscles' force is great and max at about 2/2.5 micrometres. When the muscle is fully extended and, therefore, the sarcomere is extended over than 3 micrometres, the muscle force decreases exponentially.</span>
