D. Plants have adapted to deal with the sun in many different ways, and this is one. The stomata are regulated by guard cells, which are activated by different things depending on the species of plant, and guard cells are supposed to keep the stomata from staying open all the time and losing too much water to evaporation. So, the solution is to have the stomata on the bottom of the leaf to prevent direct sunlight contact (and therefore more evaporation), and guard cells to protect the stomata.

Which situation would most likely increase the carrying capacity for humans

vredina [299]

C. A new source of freshwater

Explanation:

The situation that would most likely increase the carrying capacity for humans in a certain region is the availability of new sources of freshwater.

In ecological terms, the carrying capacity of a place is the the number of people, animals, or crops which a region can support without environmental degradation.

A new source of freshwater provides new resources for the ecosystem.
In the freshwater, more fishes are available, more plants can grow around and a lot of biological activities can progress.
Water is essential for life.
Fresh water sources are incentives for choosing to live in a place or not.
A fresh water source increases the carrying capacity for humans in a certain region.

Seeds are a derived character of the spermatophytes. All of the plants in this clade reproduce using seeds. However, embryo form

Natasha2012 [34]

Embryophyta is a clade within the Phragmoplastophyta, a larger clade that also includes several green algae groups. Embryophytes are the plants growing on land which include hornworts, liverworts, gymnosperms, flowering plants etc while green algae mostly thrive in aquatic environment.

The conduction of water requires vascular tissue called xylem. In green algae, it is not necessary to have water conducting tissue as the entire body is in contact with water. However in embryophytes, having a vascular tissue is an adaptation that ensures to provide water to the higher parts of the plant which is not directly in contact with the soil.

In what ways are autorhythmic fibers similar to and different from contractile fibers?

Leto [7]

I think Autorhythmic fibers are fibers that are self excitable or on their own for example some cardiac muscle. They repeatedly generate action potentials that trigger heart contractions.They continue to stimulate a heart to beat even when it is removed from the body. In comparison to contractile fibers, autorhythmic fibers are self excitable and do not require nervous system stimulation to trigger contractions. Contractile fibers have stable resting membrane potentials of -90mV, when a contractile fibers reaches threshold by action potential, the voltage gated fast sodium ions channels will open.

Answer:

from wind power/light winds.

Explanation:

when wind speeds get higher, soil particles roll along the surface from to a strong wind that lifts a large volume of soil particles into the air.
