What is the life cycle for a goldfish?​

Biology
1 answer:
Rus_ich [418]3 years ago
5 0

Answer:

The life cycle of a goldfish starts out as an egg. The female fish will lay about 25 eggs, but unfortunately only some grow up. The eggs usually hatch within 5 days and if you have a fish tank then you should take the adult fish out or else it may eat the eggs. After the egg hatches, it turns into a fry,(this is what a baby goldfish is called) Once they hatch, they will stay attached to the plants for two days, after that, you should start to feed them. Once they are not fry anymore, they turn into adult goldfish. If you take care of them properly, they could last up to 15 years! Once the fish are complete adults, they can lay eggs. The females rub up against plants and lays eggs while the male Goldfish sprays the eggs to make them fertilize and turn into fry.

How are key features of exponential functions determined and interpreted from a graph and table
Anit [1.1K]

Answer:

The graphs of all exponential functions have these characteristics. They all contain the point (0, 1), because a0 = 1. The x-axis is always an asymptote. They are decreasing if 0 < a < 1, and increasing if 1 < a

Explanation:

Graphs of Exponential Functions

The graph passes through the point (0,1)

The domain is all real numbers.

The range is y>0.

The graph is increasing.

The graph is asymptotic to the x-axis as x approaches negative infinity.

The graph increases without bound as x approaches positive infinity.

The graph is continuous.

Briefly explain why only chromosomes of a homologous pair can have their alleles referred toas homozygous or heterozygous
tatuchka [14]

This is due to the fact that only homologous chromosomes would have identical genes located at identical sites on those chromosomes. Otherwise, there would be no connection between the alleles of various genes.

Although the genes and loci of the two members of the homologous pair are similar, the alleles may vary.For instance, both allele possess the genes responsible for the attribute of eye colour. While the one has alleles for the blue-eye trait, other has alleles for the brown-eye trait. The homologous chromosomes are said to be heterozygous in this instance since the alleles are different.

On the other hand, when both alleles for a gene that codes for the blue-eye phenotype are present, it is said to be homozygous.
