Urine is collected in vessels and leaves the kidneys - Step 4
Beneficial molecules and water are reabsorbed into the blood - Step 3
Explanation:
Steps of urine formation are given below.
what is urine formation?Urine production is a crucial procedure for the entire body. It effects not only acid-base balance, but also blood osmolarity, plasma composition, and fluid volume, and therefore all cells in our body.Urine is formed in three stages: glomerular filtration, reabsorption, and secretion.Steps of urine formation are:-

In a "minute to win it" game, cards are placed between cups to stack them. (see the picture) The contestant then
pulls the card out in hopes that they will end with a set of stacked cups. Why does this work?
Yank Me!
Minute to Win it
Party Game
Answer:
It will work as long as the contestant is gentle but quick enough at pulling out the card from in between the stack of cups and it works because the balance is maintained as the card is yanked out from beneath the cups. Since the center of gravity does not shift for the cups, they do not fall off of one another.

What 10 good ideas would you give to improve a zoo. Explain each with a sentence.
How are oxygen and carbon connected through the atmosphere, geosphere, and hydrosphere. Give an explanation of how a plant might use all three spheres
Answer:
Explanation:
To preserve Zoological garden expertise are needed to manage the creatures that are there.
Good and conducive environment should be provided for the animals.
Routine cleaning to avoid outback of diseases
Adequate resources should be provided this include food to avoid eviction of important species.
Geosphere is made up of the crust they form the layer of soil that support growth of plant and also supply nutrients.
Atmosphere is made of gas some of which help sustain life. Example is oxygen, carbon dioxide
Hydrosphere form the liquid portion of the earth it included large water bodies that serves as habitat for aquatic organism.
Oxygen and carbon are been released into the atmosphere where they are been taking up by plant or animal dead and remains of this organism lead to the release of this gases in both organic and in organic form back into the soil where it is taken up by plants back into the atmosphere and some are washed in the water bodies.
Plants takes in carbon-dioxide from atmosphere, absorbs nutrients from the soil through their root and water from the water table needed fro their growth.
(a) If a particular gene is located on the Z chromosome of this lizard species, describe why a lizard with a ZW genotype has a greater probability of expressing the recessive phenotype for the trait than a lizard with the ZZ genotype does.
Answer:
If there is no dominant allele for a trait present on a homologous chromosome to mask the recessive allele, the recessive phenotype will be expressed. In this case, the gene is located on the Z chromosome. In an individual with a ZW genotype (female) there is no homologous Z partner, meaning whatever allele is present on the solitary Z chromosome will be expressed.

A model of a gene, DNA, and a chromosome is shown here. A researcher tags the gene with a heavy radioactive isotope (P-32). Which statement predicts the outcome of the radiolabeling on the gene, DNA, and chromosome while differentiating between the three components of the model?
Answer:
The gene will be radiolabeled, but only a portion of the chromosome will display P-32 because genes are smaller than chromosomes
Explanation:
Genes are made of DNA, but there are many (numerous) genes found along chromosomes. Only a small portion of the chromosome will be radiolabeled.
The gene will be radiolabeled, but only a portion of the chromosome will display P-32 because genes are smaller than chromosomes.
What is the relationship among DNA a gene and a chromosome?
Genes are segments of deoxyribonucleic acid (DNA) that contain the code for a specific protein that functions in one or more types of cells in the body.
Chromosomes are structures within cells that contain a person's genes. Genes are contained in chromosomes, which are in the cell nucleus.
Thus, The gene will be radiolabeled, but only a portion of the chromosome will display P-32 because genes are smaller than chromosomes.
