The ventral nerve cord makes up nearly all of the nervous system in the earthworm. It goes from the anterior (front) end to the posterior (back) end. It's function is simple; it's the nerves in the worm! If dissected, the nerve cord looks like a thin white line on the ventral (belly) side on the inside of the skin.

No, squids do not have a segmented body. They have a soft, elongated body with a distinct head, mantle, and tentacles. Their body is not divided into segments like some other invertebrates such as worms.

While humans and other vertebrates have a spinal column that runs down their back, or dorsal side, earthworms possess a nerve cord consisting of two strands that runs down their belly, or ventral side. The nerve cord of an earthworm relays impulses from receptors in the worm's anterior to posterior parts of its body.

The surface of the alimentary canal can be eroded by a variety of factors including stomach acid in conditions like gastritis or ulcers, a viral infection such as gastroenteritis, or medications like non-steroidal anti-inflammatory drugs (NSAIDs) that can irritate the lining of the stomach and intestines. Erosion of the alimentary canal can lead to symptoms such as abdominal pain, nausea, and gastrointestinal bleeding. Treatments may include acid-reducing medications, antibiotics for infections, and avoiding irritants like NSAIDs.

Animal pregnancy is commonly referred to as gestation. During gestation, the female carries and nourishes the developing offspring in her womb until they are ready to be born.

The pelvic bones in modern whales are an example of a homologous structure that has become greatly reduced in size. These bones are a remnant of the pelvis found in the common ancestor of whales and other mammals, but their size and function have been greatly reduced due to evolution and the adaptation of whales to an aquatic lifestyle.

There is really only one race of people: the Human race. What people now define as races are in fact imperfect categorizations of different physical features that people who come from within a defined geographic area have in common. It is man's nature to box and to categorize, and the "races" are just another example of this tendency with no scientifically sustainable method of drawing hard lines between the "races".

Animals like dogs, cats, and bats can hear frequencies that are higher than what humans can detect, allowing them to perceive sounds that are beyond human hearing range. Elephants can hear infrasound, which is lower than what humans can hear. Some birds, like owls and parrots, have excellent hearing abilities that enable them to detect subtle sounds in their environment.

The difference among living things depends on different DNA arrangement in the genetic order of a living thing. Offspring do not have the same genetic order as either of their parents which results in such obvious things as having different personality, look, height,etc.....

There are 7 types of guinea pigs that are recognised world wide!

The main types of guinea pigs, (the ones your mot likely to find at your pet store) Are the breeds, American and the abyssinian.

The other 5 breeds are, the teddy, peruvian, silkie, texel and coronet.

There are also other breeds that arn't classified as pure bred breeds and a classic example of this is the hair-less guinea pig.

It is not recommended to breed from the same litter as it can increase the risk of genetic health issues in the offspring due to inbreeding. Breeding from different litters helps maintain genetic diversity and reduces the risk of potential health problems.

Humans have 46 chromosomes. To be more specific, they have 22 somatic (body) chromosomes from each parent, and one sex chromosome from each parent. Added together, humans have 46 chromosomes (or 23 pairs). However different animals have different numbers of chromosmes. But under normal circumstances, each has 1 copy from each parent, and 1 copy of a sex chromosome from each parent. For instance, mice have 40 chromosomes, a horse has 64, a cat and dog both have 38, and some species of elephants have 56. It depends on the animal because each animal has a different number of chromosomes.

If a dog ingests fiberglass, it can cause irritation and damage to the digestive tract. Ingesting large amounts of fiberglass can lead to serious health issues and potentially be fatal. It is important to seek veterinary care immediately if you suspect your dog has ingested fiberglass.

Hydrophobia, or fear of water, can be prevalent in individuals with specific phobias or anxiety disorders. It is not limited to any specific geographical location but can be found worldwide in individuals with such conditions.

The name for the skeleton outside of an animal's body is an "exoskeleton." This structure provides support and protection for the organism and is commonly found in invertebrates such as insects and crustaceans.

Only if they are girls! But yes they do have periods. Otherwise they could not have babies..... No matter what I'm pretty sure that girl dogs do have periods.

So yes animals do have periods!

Niko Bellic is a fictional character from the video game Grand Theft Auto IV. He is a former soldier from Eastern Europe who comes to Liberty City in search of the American Dream but becomes involved in criminal activities. Throughout the game, players control Niko as he navigates the criminal underworld and deals with his past.

A plant converts carbon dioxide into oxygen through the process of photosynthesis. This process involves capturing sunlight energy to convert carbon dioxide and water into glucose and oxygen.

There is no evidence to suggest that Charles Darwin ever ate an owl. Darwin was a naturalist and scientist known for his contributions to the theory of evolution through natural selection, not for consuming unusual foods like owls.

An adult typically has 32 teeth, including four wisdom teeth at the back of the mouth. This includes eight incisors, four canines, eight premolars, and 12 molars. However, some adults may have fewer teeth due to conditions like impaction or extraction.

It appears that the animal that walks the most is the dog. Most people who keep dogs as pets walk them on a daily basis.

Raccoons can reach lengths of 24-38 inches (61-96 cm) and weigh between 14-23 pounds (6-10 kg) on average. However, some individuals in captivity have been known to grow larger.

Scientists call animals that cannot make their own body heat ectotherms, which means they rely on external sources to regulate their body temperature. Examples include reptiles, amphibians, and most fish.
