Yes, chordates typically have a coelom. The coelom is a body cavity lined with mesoderm that surrounds the internal organs, providing space for organ movement and protection. It is considered an important characteristic of chordates, although not all chordates have a well-developed coelom.

Nematodes have a simple respiratory system that involves gas exchange occurring through their body surface by diffusion. They lack specialized respiratory organs like lungs or gills, relying instead on passive diffusion of oxygen and carbon dioxide through their thin, permeable cuticle. This allows nematodes to exchange gases with their environment effectively despite their small size and simple body structure.

The cranium in a fetal pig, just like in humans, serves to protect the brain. It also provides structure and support for the head, and allows for the attachment of muscles and ligaments necessary for head movement.

in my experience it's about 4 to 5 hairs per week

It can take cotton anywhere from a few weeks to several months to break down, depending on various factors such as moisture, temperature, and microbial activity in the environment. Generally, cotton is biodegradable and will decompose relatively quickly compared to synthetic fabrics.

Yes, some species of mammals, such as monkeys, apes, and some bats, have menstrual cycles similar to humans. Other animals, like dogs and cats, have estrous cycles, which are similar but do not involve a shedding of the uterine lining like human periods.

Generally, this is due to a nail biting habit. If you don't mind the aesthetics, don't do anything. If you do, consider nail biting cessation techniques. Either way, your nails will be permanently on the short side.

I have a girlfriend who is a major nailbiter. Her nails are about 5 mm long on average. I felt bad for her and let her start biting my nails, something she asked to do when her nails "ran out" of anything left to bite. She does it when we watch TV, in the movie theater, even while entertaining close friends (!).

Needless to say, after some years, my nails are about half their original length with a very similar "puff" on the finger tips that you've noticed in yours, presumably. They now look like the nails of a long term nail biter...even though I don't bite them that much (actually started after she began working on them. I couldn't stand their uneven tips and now I do it unconsciously at times).

But it did help her to grow her own nails, meaning the white part since her pink part became permanently shortened.

It worked but, truly, I don't think I would have let her start if I had to do it over again. I used to be able to pick things off the floor easily but not now.

Yes, lions have a white section in the corners of their eyes called the sclera. This white part helps lions communicate with other members of their pride by showing emotions and intentions through eye movements.

A density dependent factor is a limiting factor that depends on population size. A Density-independent limiting factor affects all populations in similar ways, regardless of the population size. Its in my biology book.

The human alimentary canal, or digestive tract, is approximately 30 feet in length and consists of the mouth, esophagus, stomach, small intestine, and large intestine. Its main function is to digest food, absorb nutrients, and eliminate waste from the body.

In the canine: the gluteal muscles (superficial, middle, deep).

Yes, sepia eyes in Drosophila are a recessive trait. The sepia eye color phenotype is caused by a mutation in the gene that encodes the enzyme dopachrome isomerase, resulting in the brown eye color characteristic. Two copies of the mutated gene are required to exhibit the sepia eye color phenotype.

The concept of ecological pyramid was introduced by Charles Elton in 1927 in his book "Animal Ecology". It is a graphical representation of the trophic levels in an ecosystem, showing the flow of energy and biomass from one level to the next.

The umbo on a clam is the oldest part of the shell and can typically be found at the hinge of the two shell halves, closest to where they join together. It is usually more elevated and centrally located compared to the rest of the shell. Observing the position of the umbo can help determine the age and growth pattern of the clam.

Animals hear sound when sound waves enter their ear canal and vibrate the eardrum. This vibration is transmitted to the inner ear where it is converted into nerve signals that are sent to the brain for processing. Different animals have variations in their hearing structures that allow them to detect and interpret sounds in their environment.

Living things reproduce to ensure the continuation of their species and to pass on their genetic traits to future generations. Reproduction is essential for the survival of a species and helps to maintain genetic diversity which can increase chances of survival in changing environments.

Living things are grouped into different categories based on their shared characteristics and evolutionary relationships. This organization is known as taxonomy and helps scientists study and understand the diversity of life on Earth. The most common levels of classification are domain, kingdom, phylum, class, order, family, genus, and species.

Yes, consuming fiberglass can be extremely harmful to dogs and potentially fatal. Fiberglass can cause internal injuries and blockages in the digestive system, leading to serious health issues. It is important to seek immediate veterinary help if a dog has ingested fiberglass.

Pregnancy in a female dog lasts nine weeks.

We determine the birthing date from the date of the first mating.

Some bitches will whelp (deliver their puppies) anywhere from day 59 to day 63.

As the owner, you will make no changes to her diet for the first 5 weeks.

Often, in the 3rd week after mating, she will go off her food for about 10 days.

You will notice that her vulva - the area around her vagina, did not return to the normal small size it was before mating, but looks rather enlarged.

There is normally no discharge during a pregnancy.

If you do see a discharge, then take her to the Veterinarian.

She may have an infection, or be losing the litter, or have developed a case of Pyometra, which, if left untreated, can kill her.

She needs a good exercise program, which involves a daily run to make sure all her muscles, including her uterine muscles, are in top condition.

She also needs a very high quality diet.

This is not the time to scrimp on her feeding formula.

Mother Nature tries to insure the survival of the species, so if the diet is lacking in any ingredient ,calcium or zinc for example, the developing puppies ( whelps) will take from the mother's body what they need to grow healthy, and therefore her body will become depleted.

DO NOT ADD ANY VITAMIN SUPPLEMENTS IN THE FIRST MONTH OF PREGNANCY.

BIRTH DEFECTS WILL DEVELOP FROM TOO MUCH VITAMINS A & D.

DO NOT GIVE ANY MEDICINE NOW EITHER WITHOUT THE EXPRESS ORDER OF THE VETERINARIAN.

At week 5, her nipples will become deep pink in colour, and you may notice that she is thicker around the waist and broader around the rib cage.

Now you should increase her feeding by 25%.

Give her a daily Vitamin supplement from your Veterinarian

At week 6, increase her feeding again by 25% and divide her feedings into 2 meals a day.

You will notice that she is sleeping a little more now.

At week 7, increase her meal amount again by 25%.

Begin making preparations for the arrival of the puppies.

Build a whelping box for her and put it in a quiet room where she will be undisturbed by other pets and people and in an area that is easy to keep warm.

If you are putting the whelping box in a basement, then buy heavy weight plastic drop cloths, to hang 'walls' from the ceiling or beams to keep the heat inside the whelping box area.

Decide how you will heat the area where the new puppies will be.

It needs to be about 85 degrees until they are 3 weeks old.

A baseboard heater will do the job, as long as the dog cannot get near the electical cord or get burned by the heater.

You'll need to have it out of reach.

You will need reams of newspapers for the puppy box.

At week 8, increase the feed again by 25%. She is now eating double her normal amount.

Begin feeding her 3 times a day now and make the exercise time shorter, but more frequent.

Walking will be very tiring for her and she is very uncomfortable through the last week of the pregnancy.

Begin taking her temperature rectally twice a day.

The normal dog temperature is about 100.3F - 101.3F.

It will normally drop to about 98. degrees F 8 - 24 hours before the onset of labour and she will refuse to eat or drink anything.

NEVER EXPECT YOUR DOG TO DELIVER A LITTER BY HERSELF.

Although animal whelping is a 'natural event' this does not mean that the animal does not get into serious trouble if left unattended.

Mother and puppies frequently die because the owner thoughtlessly left her alone during this crucial time.

A digestive chamber with one opening is called a gastrovascular cavity. This structure is typically found in simple organisms such as cnidarians and flatworms, where it serves both digestive and circulatory functions.

The blue whale has the biggest stomach of all animals. It is capable of stretching to accommodate large amounts of krill, its primary food source.

The largest species of leeches can grow up to 16 inches (40 cm) in length, although most species are much smaller, averaging around 3-4 inches (7-10 cm). Size can vary depending on the species and their environment.

Yes, annelids have a true coelom that is lined with mesodermal peritoneum. This coelomic cavity houses their organs and provides space for movement and circulation of fluid.

Wind pollination is the best reproductive adaptation for an area without wildlife as it allows plants to transfer pollen without relying on animal vectors. This strategy doesn't require specific animals for reproduction, making it more efficient in isolated environments.

A woodlouse has 14 body parts: seven pairs of legs and a segmented body composed of a head, thorax, and abdomen.
