How do wetlands help keep our water supply pure?

Fofino [41]

Most people in the world get our water from rivers and lakes, including the vast majority of the world’s poorest people.

But half of the world’s 500 most important rivers – water sources for hundreds of millions of people – are being seriously depleted or polluted.* Approximately 40 percent of the rivers in the U.S. are too polluted for fishing and swimming.**

Water shortages will likely be a fact of life for most people on the planet within the next ten years.*** We can’t afford to pollute and destroy our drinking water sources. But that’s exactly what we’re doing – often without knowing it.

Forests, grasslands and wetlands are nature’s water filters. They help keep erosion and pollution from flowing into our waters and they slow rainwater down, sending more water into underground supplies. But every year we lose 32 million acres of forest – that's a lot of water filters, gone, every year.

We are facing dirtier, unsafe water and more risk of water shortages and scarcity. This crisis is real, it’s happening now and it’s getting worse fast.

The Nature Conservancy partners with people communities in all 50 states and 30 countries to protect water sources. We work on the ground to:

Prevent deforestation and destruction of grasslands – nature’s water filtersRestore forests and grasslands that have already been lost or damaged and sending erosion into our watersEquip farmers with practical ways to keep harmful run-off out of our watersRestore floodplains that act as sponges and send water down into groundwater supplies and filter pollution out of riversCreate new science that helps pinpoint the greatest threats to our waters and the most effective ways to combat them

But we understand that nature won’t solve everything, so we’re finding new ways to reduce water use. More than 70 percent of water withdrawn from nature goes to agriculture, so we’re helping farmers access new technologies and practices that use less water while continuing to produce the food we need.

After prostate surgery a client’s indwelling catheter and continuous bladder irrigation (CBI) are to be removed. The nurse discu

Verizon [17]

Answer:

The options

1

Have dilute urine."

2

Be unable to urinate."

3

Produce dark red urine."

4

Experience some burning on urination."

The CORRECT ANSWER IS 4

4

Experience some burning on urination."

Explanation:

Due to the trauma affecting the mucous membranes of the urinary tract, burning on urination is a more likely response, this sensation gets to reduce with time. This will stop the urine from further dilution once the frequent continuous bladder irrigation is stoped and removed. Although, the urine may show a slight pink tinge which results from the trauma after the surgery and the effect of the catheter that is noticed. A difficulty to urinate won't be felt except the indwelling catheter is removed earlier than it should expected and edema still occurs in the urethra. Production of dark red urine is an indicative factor for hemorrhage, which ought not to be seen.

Achondroplasia is an autosomal dominant genetic disorder in humans. If a man with Achondroplasia ( heterozygous) and a normal wo

tresset_1 [31]

Answer and Explanation:

Achondroplasia is a form of dwarfism that affects the formation of cartilage; early in development, most of the skeleton is comprised of cartilage. Cartilage is a type of flexible, tough tissue; in achondroplasia ossification (conversion of cartilage to bone) is affected. Symptoms include an enlarged head, shorter upper and lower limbs, and limited motion at the elbow.

Punnett squares are illustrations that display the product of hybrid trait crosses by genetic breeding.

For this cross...

Assuming Achondroplasia= dominant

Parent generation or P generation:

gametes: An → Achondroplasia dominant (A), No Achondroplasia recessive (n)

Heterozygousity describes the allelic makeup; these traits comprise two varying forms of a gene. However, homozygous traits comprise identical forms of the gene.

Male: An → with Achondroplasia

Female: nn → without Achondroplasia

genotypes and phenotypes for parent and offspring...

Assuming heterozygousity of the male , for the cross

P generation: An × nn

Achondroplasia × No Achondroplasia

F1 generation:

genotype: An × nn ...(from punnet square)

phenotype: 2 with Achondroplasia ; 2 without

∴ 50% are genotypically heterozygous while 50% is homozygous , 2 with Achondroplasia ; 2 without
