The main organs of the excretory system are the kidneys, ureters, urinary bladder, and urethra. The kidneys filter the blood, produce urine, and are integral in maintaining the body's water and electrolyte balance. This intricate process involves filtration, reabsorption, and secretion.
The main organs of the excretory system are the kidney, ureter, urinary bladder, and urethra. The kidneys are a pair of bean-shaped structures that filter blood and produce urine. This urine then travels through the ureters to the urinary bladder, where it is stored until it is eliminated through the urethra. The kidneys play a critical role in maintaining the balance of water and electrolytes in the body, and they achieve this through a series of three steps: filtration in the nephron, reabsorption of nutrients back into the blood, and secretion of additional waste. To achieve this, kidneys consume around 25 percent of the oxygen absorbed by the lungs, which is used to generate energy in the form of ATP through aerobic respiration.

Answer:Long term drought, change of season from winter to summer, forest fire are unfavorable environmental factors which can deplete the amount of resources already available with the ecosystem. The long term drought will be a condition in which the ecosystem will suffer from non-availability of water.
Explanation:
Light is a wave but does not have frequency as a property.
Light is exactly similar to water and sound.
Light is a converse wave.
Answer:
Light is a transverse wave.
Explanation:
Light is a transverse wave. Its particles vibrates or oscillates in the direction perpendicular to the direction of propagation of wave.
Light wave also have both electric and magnetic field component. So, light waves are also called as electromagnetic wave. Another type of wave is longitudinal wave. In this type, the particles of wave are in the direction of propagation of wave.
Hence, the correct option is " light is a transverse wave ".
The abyssal zone is the zone of the ocean where seaweed and fungi are present.
The abyssal zone is a layer of the ocean where seaweed and fungi are present. "Abyss" is a Greek word which means bottomless. This zone is located at the depths of 4,000 to 6,000 metres.
So we can conclude that the abyssal zone is the zone of the ocean where seaweed and fungi are present.

Answer:
this is called Forced Speciation Explanation:
The F1 progeny will all have the genotype Zz and will all have normal feathers. When the F1 progeny are interbred, the F2 progeny will have the following genotypes and phenotypes:25% ZZ (bald)25% Zz (normal)50% zz (normal)The expected proportions for the F1 and F2 progeny are as follows:F1: 100% Zz (normal)F2: 25% ZZ (bald), 25% Zz (normal), 50% zz (normal)
In chickens, congenital baldness is due to a z-linked recessive gene. T
his means that the gene for baldness is located on the Z chromosome and an individual must have two copies of the recessive allele to exhibit the bald phenotype.
The bald rooster has the genotype ZZ, meaning he has two copies of the recessive allele. The normal hen has the genotype Zz, meaning she has one copy of the recessive allele and one copy of the dominant allele.
When these two individuals are mated, all of the F1 progeny will have the genotype Zz and will have normal feathers. When the F1 progeny are interbred, the F2 progeny will have the following genotypes and phenotypes:25% ZZ (bald)25% Zz (normal)50% zz (normal)
The expected proportions for the F1 and F2 progeny are as follows:F1: 100% Zz (normal)F2: 25% ZZ (bald), 25% Zz (normal), 50% zz (normal)
