Are Parakeets good starter pets? why or why not
pishuonlain [190]

Answer:

NO! They require a ton of attention, a large cage, and experience with birds. Parakeets are often marked as starter pets, but no, they are not.

First, they need a 3 feet long cage with 5+ toys that need to be changed each month. And they need natural perches, not the cheap wooden dowels, they will get feet problems. Most people don't do this, having a bored pet.

Second, parakeets will chew anything given/available to them, and a lot of things can be toxic to them, which can lead to the death of your pet.

Third, parakeets are messy and noisy. They poop a LOT and love to toss seeds around their cage. They also need millet and a calcium chew, which are also messy.

They also will want a friend, they are flock animals in the wild so 3-4 birds is a good number, but getting more birds means getting a large cage. The pet store will tell you it's fine, but it is not. ALWAYS SEEK HELP FROM A BIRD BREEDER.

Lastly, they need a bird proofed room to fly around in. No matter how large your cage is, they still need some out-of cage time.

Try a dove or pigeon instead, they are listen the #1 easiest and cheapest to care for pet bird.

Which hypothalamic hormone contributes to the regulation of the male reproductive system? a. luteinizing hormone b. gonadotropin
Lostsunrise [7]

Answer:

The correct answer is option b. gonadotropin-releasing hormone.

Explanation:

The GnRH or the gonadotropin-releasing hormone is a releasing hormone that releases from the neurons of the hypothalamus. This releasing hormone is responsible for the secretion of the luteinizing hormone and follicle-stimulating hormone.

GnRH regulates both gonadotropin hormones, in which, LH (luteinizing hormone) responsible for the regulation of the male reproductive system and FSH (follicle-stimulating hormone) responsible for the female reproductive system and sperm production in testes in males.

Thus, the correct answer is option B. gonadotropin-releasing hormone.

topjm [15]

Evolution's patterns manifest as nested similarities. nesting occurs between molecular sequences of evolutionary related organisms and between the different taxa arranged in a phylogenetic tree. True

Phylogenetic tree is a branching diagram that shows the evolutionary relationships between various species.

Nesting behavior is an urge in the pregnant animal to prepare a home for the upcoming generation which occurs due to increase in the amount of estradiol to protect them from predators and environment.

Nesting behavior is also taken consideration to understand the phylogenetic similarities between various species.
