Nookie1986 [14]
<span>Let's consider a scenario in which the resting membrane potential changes from −70 mV to +70 mV, but the concentrations of all ions in the intracellular and extracellular fluids are unchanged. Predict how this change in membrane potential affects the movement of Na+. The electrical gradient for Na+ would tend to move Na+ Outside the cell (extracellular) while the chemical gradient for Na+ would tend to move Na+ Inside the cell (intracellular).

The electrical gradient is defined as the + goes to the - and the - goes to the +
Na + has a positive charge, but there's more positive charge inside the cell than outside (due to potassium), therefore, Na+ goes extracellular (out)
The concentration gradient considers that the ion will go from the most concentrated to at least concentrated by passive diffusion so no trans-membrane proteins in the game attention.Na + is very concentrated in extracellular and few intracellular, therefore, it tends to go intracellular (in).</span>

A "Cuckold bee" is a common term to describe several different kleptoparasitic lineages in Apoidea.
damaskus [11]

Answer:

True

Explanation:

In biology or animal behavior, the term cuckold refers to the act of invading a strange net. The term might be applied to different species that parasite other species. A very well known example is the cuckoos bird.

The Cuckold bees or cuckoo bees are many parasitic species belonging to the Apoidea taxon that characterize for invading nests of other bees.

Females lay their eggs in the cells of the host nest. Depending on the species, the intruding female might kill the owner larvae of the cell, or the emerging parasitic larvae is the one that can destroy the host using their highly developed mandibles as weapons.

As they develope, foreign larvae feed on the foodstuffs that the female owners of the nests bring for their own offspring.

How much of the earths surface do desserts cover and where do they occur? What are the four major types of dessert?​
dem82 [27]

The deserts are actually one of the most common and widespread landscapes on the planet Earth. The deserts, combined of all types, are covering around 33% of the landmass, thus one third of the whole landmass on the planet.

These multiple types of deserts, like the hot and dry desert type, cold desert, coastal desert, semiarid desert. All of them have their own unique characteristics that define them more specifically. The hot and dry deserts are the ones that are hot throughout all of the year, also being located deeper into the mainland. The cold deserts are found in the Northern Hemisphere, they have hot summers and very cold winters. The coastal deserts are located along the coasts, so despite being very dry, they do tend to have high humidity. The semiarid deserts are deserts that are not as dry as the other types, they receive more rainfall, though that happens just in few days of the year, so they are dry for the most of it again, with the biggest difference being that they have slightly more vegetation.
