Kidneys are often compared to filters because they cleanse unwanted waste from both frogs and humans true or false ?
PtichkaEL [24]

"Kidneys are often compared to filters because they cleanse unwanted waste from both frogs and humans" is TRUE.

Answer: Option A

<u>Explanation: </u>

Frogs also have the excretory system with two kidneys and similar to mammals. Its function is to eliminate the nitrogen product from the blood. Frogs make large volumes of dilute urine to wipe out harmful products from the tubules of the kidneys.

Tadpoles and aquatic frogs excrete the nitrogen as ammonia, but most terrestrial adults excrete it mostly as urea which is less threatening substance. A few tree frog species with little water access excrete the still less harmful uric acid.

How do the process of DNA replication and the laws of inheritance help cells and individuals pass on their
Lapatulllka [165]

Answer/Explanation:

DNA replication doubles each chromosome, meaning the cell can pass on DNA to daughter cells - the duplicated DNA is divided equally between the two new cells formed from the parent.

The laws of inheritance are:

1) The Law of Dominance: An organism with alternate forms of a gene, called alleles, will always display the form that is dominant, masking the recessive trait.

2) The Law of Segregation: In a diploid genome, like most eukaryotes, each trait is defined by a pair of genes (alleles). Each allele is randomly passed on to the gametes so that each gamete only contains one allele.   The offspring inherits one allele from each parent during the process of fertilization.

2) The Law of Independent Assortment: Genes for different traits are sorted independently from one another That is, the inheritance of one trait does not depend on the inheritance of another trait. so that the inheritance of one trait is not dependent on the inheritance of another.

Why are math assignments like the water that is found on the ground in the early morning?
VikaD [51]
This is because the water is dew.  
Maybe we should probably check how that what gets to the ground in the morning. At the point when the surface of a question winds up plainly colder because of sending its idle warmth out, the current dampness in the air contracts among itself.
