Answer:
observation gives you answers. Patterns, motion, matter, time etc
Answer:
<u>The four stages of labor:</u>
The first stage of labor
In the first stage of labor the Thinning (effacement) and opening (dilation) of the cervix. This is called effacement and dilation(of the cervix).
The process is explained systematically and its very very simple to say that When the cervix dilation happens and mucus strings from vulva placenta is delivered then the child birth is near.
Explanation:
- <u>The first stage of labor has three parts:</u>
- Early labor:The cervix opens to 4 centimeters. <em>The female will probably spend most of early labor at home.</em> The female should keep herself busy in doing her usual activities. Relax, rest, drink clear fluids, eat light meals if she wants to, and keep track of her contractions.
- Active labor: The cervix opens from 4 to 7 centimeters. This is when the female should head to the hospital. When she has contractions every 3 to 4 minutes and they each last about 60 seconds, it often means that the cervix is opening faster (about 1 centimeter per hour).
- Transition to second stage: The cervix opens from 7 to 10 centimeters. For most women, this is the hardest or most painful part of labor. This is when the cervix opens to its fullest.
- <u>Second stage of labor</u>
- The baby moves through the birth canal
The second stage of labor begins when the cervix is completely dilated (open), and ends with the birth of the baby.<em> Contractions push the baby down the birth canal, and the female may feel intense pressure, similar to an urge to have a bowel movement.</em>
- <u>Third stage of labor</u>
- Afterbirth: The uterus continues to contract to push out the placenta (afterbirth).
- <u>Fourth stage of labor</u>
- Recovery:Nursing right after the birth of the baby will help the uterus to contract and will decrease the amount of bleeding.

Answer:
b) x: fin
y: lateral line
z: swim bladder
Explanation:
The <u>dorsal fin</u> is found in the dorsal region of the fish body. Depending on the species, there can be one or two dorsal fins. Membranous structures and bony or cartilaginous ratios compose the fins. One of the main functions is to stabilize the body in water, providing equilibrium. When the dorsal fin is erect, it acts as a keel, helping the fish not to turn aside. Fishes also use these fins as protection because the cartilaginous or bony ratios act as spines. The animal uses these spines to defend itself from predators. The morphological variety of dorsal fins in the different species is used in taxonomy.
The <u>Lateral Line</u> is a system or sensory organ composed of special receptors called neuromasts, which can be found all along the lateral region of the animal. The lateral line perceives information from the environment, such as light, sound, or water movement, among others. These signs are translated into nervous messages. The lateral line is useful to detect prey, predators, other animals moving, objects, etcetera. It is significant for intraspecific interaction, especially during swimming motions in schools. The lateral line receives perturbations of short distance, generated by other living beings or by objects. Some studies confirm that the lateral line is also sensitive to chemical stimuli.
The<u> swim bladder</u> is a neumatic sac-like structure filled with gases coming from the blood. Its main function is to allow neutral floating and let the animal in suspension at any depth, with no need for muscular effort. The animal can regulate the size of the bladder. This organ can be found in most pelagic fishes, while the benthonic ones or the ones that actively swim lack it.
