Animal Behavior

Crocodiles are apex predators and are typically at the top of the food chain, meaning they have few natural predators. However, larger crocodiles may occasionally be targeted by other crocodiles, big cats (like lions and tigers), and large snakes. Additionally, humans are threats to crocodiles due to hunting and habitat destruction.

1. DNA in an individual mutates. This happens all the time in everyone, otherwise we´d all be exactly the same! Mutation account for differences between people.

2. If a mutation is beneficial to an animal, for instance helps it survive by making it better at catching prey, more attractive to the other sex, or capable of having more young, it will be passed on to the next generation because the animal lived longer and had more young. This is simple inheritance. Natural selection selects the animals best at surviving and lets them pass on the succesful genes.

3. If this goes on for long enough the mutation will become fixed and the population will have changed. It can be as small a change as slightly longer teeth, slightly better camouflage or more potent venom.

4. After a long time, say millions of years, small changes will accumulate and together they will have changed the species very much, probably into a new species or lots of new species. A lot of microevolution piled up makes macroevolution.

Animals with a segmented body plan belong to the phyla Arthropoda, Annelida, and Chordata. Segmentation involves the repetition of body units along the length of the organism, which can be seen in arthropods with their jointed limbs, annelids with their repeated segments, and chordates during embryonic development.

Evolution through natural selection occurs slowly over millions of years. It has been hypothesized that evolution is the result of positive mutations that occur in a community of organisms that help them survive better. Evolution is essentially descent with modification.

Cows are animals that make a "moo" sound.

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.

Tadpoles typically hatch in the spring or early summer when water temperatures are warmer and more conducive to their development. This timing allows them to take advantage of abundant food sources and ensures that they have enough time to grow and metamorphose into frogs before winter.

Decomposition is a gradual process where microorganisms break down animal tissue, releasing nutrients back into the environment. This important ecological process plays a role in nutrient cycling and soil formation.

Mountain lions are known to prey on pronghorns, but they are less likely to target armadillos due to their smaller size and defensive capabilities. Mountain lions typically hunt larger prey like deer, bighorn sheep, and elk, but they have a varied diet and may opportunistically consume smaller animals if the opportunity arises.

According to Bishop Berkeley, matter is real because it is perceived by minds. He argued that the existence of matter depends on its being perceived or sensed by a mind, either human or divine. In the absence of any mind to perceive it, matter has no existence.

Seamonsters do not actually exist in reality, but in mythology and folklore. In those stories, seamonsters are often depicted as having gills or the ability to hold their breath for long periods of time underwater.

Morphological plasticity is the tendency of a species to physically change appearance due selective breeding. Some species, like dogs, have a high degree of morphological plasticity - a few generations can turn a wolf into a chihuahua - whereas others, such as humans, have such a low degree that thousands of years of separation yields only minor changes to facial structure and hair type.

The mechanisms which govern this effect are complex and numerous, but there seems to be a correlation between high plasticity and the species' natural rate of environmental adaptability.

Crocodilians have a transparent nictating membrane which serves as a secondary eyelid. This inner eyelid moves from the sides while the outer eyelid moves up and down. When this transparent eye-lid is engaged, it does limit visual ability somewhat, especially in muddy, darker water. However, it protects the main eye from damage that may be caused by debris in the water (or even during scuffles with fellow crocodilians). When visual ability is limited, crocodilians have a keen sense of smell to help back them up.

Welll lets see. Jalli is a constinatly having sex or threesoms with broomsticks kind of pair. they enjoy sucking on each other and having "funn" in pretty much EVERY wayy possible. josh the female of the two thinks hes so frickin cool by making funn of the retared ~his loved mate. and that he and his best frannd "morning wood" are super fly.......... but really..... Darby~Winner!

Sometimes hunting dogs, such as Beagles, are raised in a pack setting. Hunters come from all over in groups for fox hunts and such. When they let their dogs loose during the hunt, when getting them back together, it can be a bit troublesome. The numbers in the ear tell the hunters/ owners if they have the right dog or not.

reporduction by meiosis produces offspring that are genetically varied allowing them to adapt adversly to their environments and have more chance of survival as with mitosis there are no genetic variations and therefore the animals would only be adapted to survive in a stable environment similar to their parent/s

Yes, I believe it is true that spiders crawl into your mouth at night. My friend told me that an average of 9 spiders crawl into your mouth at night. But im not sure if that is true so do some reseach or something to find out if it is. :o)

It is usually because the female is pregnant, or could be the following:

-Hormonal issues (NOTE: Do not worry, this is natural, just separate them)

-The male has failed an attempt at mating with the female

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.

Starling effect refers to the relationship between cardiac muscle fiber length and contractile force. In medical terms, Starling effect can manifest in conditions like heart failure where the heart muscle is unable to pump efficiently, leading to symptoms such as fatigue, shortness of breath, and fluid retention in the body.

Nocturnal animals are active during the night and have adapted to low-light conditions. They have special adaptations like enhanced night vision, acute hearing, and a keen sense of smell to help them navigate and hunt in the dark. Additionally, many nocturnal animals have a unique circadian rhythm that allows them to be most active when their prey is also active.

That depends on what you mean by "mean." Chimps are wild animals, so their behavior is obviously going to conflict with what is considered normal decorum by human standards. Males are very territorial, meaning they are willing to harm any individual that they deem a threat. They have even been known to kill and eat the babies of their own species. However, they are gentle to those within their family units. Chimps have built in social mechanisms for reconciliation. That is, if they get into fights, they will eventually mend the rift through hugging, kissing, food sharing, and grooming. Bonobos, a close cousin of the Chimp, even have non-reproductive sex in order to calm nerves.
