The average expiratory reserve volume or ERV is 810.

<h3>What is expiratory reserve volume?</h3>
  • Expiratory reserve volume or ERV is the amount of air that is exhaled forcibly.
  • This can be measured using a spirometer and is used to detect restrictive lung diseases.
  • It is the maximum amount of air that can be exhaled after normal tidal volume is exhaled.
  • Respiratory volume is the volume of air which is either inhaled, exhaled or stored in your lungs.
  • The doctors estimate the reserve volume with the help of spirometer to determine some lung diseases.
  • Once diagnosed with a lung disease, spirometry is used to monitor it.
  • Here, 3 readings of ERV are taken, calculate the sum of the these and divide by 3 to calculate the average ERV.
  • ERV= (800+ 850+ 780)/ 3= 810

Multicellular gametophytes are the product of spores from ____​
jolli1 [7]

Answer:

In bryophytes, the sporophyte is minute and dependent on the relatively prominent and nutritionally independent gametophyte for resources. The moss gametophyte looks like a miniature herb, with tiny leaf-like photosynthetic organs. The gametophyte generation begins as a dormant spore, which germinates under appropriate conditions to produce filamentous and branching protonemal tissues. These form multicellular bud-like structures, each of which develops into a leafy shoot. The mature gametophytes produce male and female sexual organs, the antheridia and archegonia, respectively. The gametophyte is often sexually distinct, and plants are either male or female.

Each antheridium has an outer layer that encloses and protects thousands of motile sperm, which swim through available external water layer to the egg. Fertilization at the base of the cylindrical archegonium produces a diploid zygote which develops into an unbranched sporophyte. The sporophyte consists of a thin stalk attached to the gametophyte, and a capsule that encloses the sporophytic meiotic cells.

In recent years, the mosses Physcomitrella patens and Funaria hygrometrica have emerged as attractive model systems for studying gene function in non-vascular plants because of the relative ease of molecular manipulation by homologous recombination. Mutants affecting gametophyte development have been isolated and their analysis should provide insights into the molecular basis of gametophyte development in mosses.

Explain how living things, such as people and trees, are different from nonliving things, such as rocks and the tent.
Natali5045456 [20]
For starters, humans have feelings and cells. If we get hurt we can feel things such as pain unlike a tent. If you hit a tent there is nothing it feels because it has no feelings. We have cells all through our body and rocks don't. They are made of other stuff but not cells.

What is the function of mRNA?
vredina [299]

Messenger RNA (mRNA) carries the genetic information copied from DNA in the form of a series of three-base code “words,” each of which specifies a particular amino acid. Transfer RNA (tRNA) is the key to deciphering the code words in mRNA
