Answer:
The absorption of water by the roots of plants is through the osmotic gradients between the soil and the plants xylem vessels.
The high the osmotic gradients the faster the water uptake though the sieve tubes in the plants. The movement of water from the soil into the roots is by osmosis and root pressure.
In a normal soil Osmosis is the movement of water molecules from the region of higher water potential(soil) to the region of lower water potential(plant roots) though a semipermeable membrane.
Therefore a soil with high salt concentration the higher salt would affect the osmotic potential and few water molecules would be able to move from the roots into the roots. This is because the more salt molecules reduced the water potential for water molecules to move through the root by the root pressure initiated by osmosis to form transpiration pull and stream in stems.
Since the loss of water in transpiration comes from water absorbed by the roots through osmosis, root pressure ,transpiration stem and pull, ,the reduced absorbed water leads to reduced transpiration.
2.
The loss of water from the leaves is through stomata. These are usually open for water loss by transpiration .During evening they are close. Therefore transpiration stream amd pull do not take place, so little water absorbed from the soil and water s conserved in plants.
Thus transplant done during the evening gives the seedlings chances of survival because the closed stomata ensues waters conservation, and less stress on the roots which prevent transpiration through the stomata..

Which air mass would produce warm, humid weather in the summer?
Answer: maritime tropical air mass
Explanation: The oceanic tropical air mass regularly creates a warm, muggy climate in the mid-year. The air mass begins from over the warm water of the jungles and Gulf of Mexico, where warmth and dampness ordinarily move to the air above from the water beneath.

What happens to the cells of a person who has cancer?
Explanation:
Cancer happens when cells that are not normal grow and spread very fast. Normal body cells grow and divide and know to stop growing. Over time, they also die. Unlike these normal cells, cancer cells just continue to grow and divide out of control and don't die when they're supposed to.

C.It is a frameshift mutation that changes many amino acids.
Explanation:
Due to the triplet nature of gene expression by codons, the insertion of the single Adenine nucleotide will disrupt the reading frame of the gene (frameshift mutation), such that it is no longer evenly divisible by three.
Thus, resulting in a completely different translated protein from the original.

Why don't negative mutations usually increase in frequency in populations?
Answer:
Within a population, each individual mutation is extremely rare when it first occurs; often there is just one copy of it in the gene pool of an entire species. But huge numbers of mutations may occur every generation in the species as a whole.

Explanation:
What is the main relationship among archosauria, diapsida, and reptilia clases?
Answer:
Archosauria (the "ruling reptiles") is a major group of diapsids, differentiated from the other diapsids by the presence of single openings in each side of the skull, in front of the eyes (antorbital fenestrae), among other characteristics. This continues the tetrapod trend of the reduction of skull bones by the fusion of multiple bones and the opening of fenestrae in the skull. This helps to lighten the skull, provides more room for muscles and other tissues, and allows more skull flexibility (kinesis) when eating. Other typical archosaurian characteristics include another opening in the lower jaw (the mandibular fenestra), a high narrow skull with a pointed snout, teeth set in sockets (called thecodont tooth implantation), and a modified ankle joint.
Diapsids ("two arches") are a group of amniote tetrapods that developed two holes (temporal fenestra) in each side of their skulls about 300 million years ago during the late Carboniferous period.[1] The diapsids are extremely diverse, and include all crocodilians, lizards, snakes, tuatara, turtles, and birds.[2] Although some diapsids have lost either one hole (lizards), or both holes (snakes and turtles), or have a heavily restructured skull (modern birds), they are still classified as diapsids based on their ancestry. At least 7,925 species of diapsid reptiles[3] exist in environments around the world today (nearly 18,000 when birds are included).
Reptilia, presented as a Class in our classification, includes turtles (Testudines), snakes and lizards (Lepidosauria), crocodiles and their relatives (Crocodilia), and birds (Aves), as well as a number of extinct groups.

3. Synthesize in your own words, explain why scientists believe that threats to amphibians present a warning about a number of environmental threats to Earth's biodiversity Refer to the Case Study.
Explanation:
Scientists give three reasons. First, amphibians are sensitive biological indicators of changes in environmental conditions such as habitat loss, air and water pollution, ultraviolet (UV) radiation, and climate change.Amphibians are sensitive biological indicators of environmental circumstances such as habitat loss, pollution of the air and water, ultraviolet (UV) radiation, and temperature change.
What is biodiversity?The variety and variability of life on Earth is referred to as biodiversity or biological diversity. A measure of variation at the genetic, species, and ecosystem levels is called biodiversity.
Biodiversity refers to the variety of all the diverse species of organisms that dwell on our planet, including the plants, animals, insects, and microorganisms.
Each of these things exists in a delicate balance and coexists with the others in ecosystems that nourish and sustain life on earth.
Amphibians are sensitive biological markers of changes in environmental conditions like temperature, UV radiation, habitat loss, and air and water pollution.
Thus, scientists believe that threats to amphibians present a warning about a number of environmental threats to Earth's biodiversity.
