The thin, protective mucous membrane composed of nonkeratinized stratified squamous epithelium with numerous goblet cells that is supported by areolar connective tissue is known
The conjunctiva is a thin transparent mucous epithelial membrane that lines the inner surface of the eyelids made up of goblet cells whose function is to protect the eyeball.
The conjunctiva is an almost transparent membrane that covers the white part of the eye, the sclera, and also the eyelids on the inside.
Its function is to protect the eyeball from external agents, although it also intervenes in the formation of tear components and in the immune defense of the eye.The conjunctival epithelium is a non-keratinized squamous stratified epithelium like the corneal epithelium but contains mucin-secreting goblet cells that maintain the tear layer.Therefore, we can conclude that the conjunctiva is a mucous membrane that is formed by non-keratinized squamous epithelium whose function is protective and lubricant.

A small earthquake, called a foreshock, can occur seconds to weeks before a large
earthquake.
Answer:
false
Explanation:
aftershock, a smaller earthquake that occurs after a previous large earthquake, in the same area of the main shock.
Answer:
The answer is Actually True!
Explanation:
Sometimes, clusters of small earthquakes called foreshock sequences come in the days or weeks before a large earthquake. Less often, seismologists have observed a process called nucleation, where the rate of slip along a fault ramps up gradually before an earthquake. Hope this helps!!!

in a neuron, sodium and potassium concentrations are maintained by the sodium-potassium exchange pump such that __________.
Answer:
the sodium concentration is higher outside the cell than inside the cell and the potassium concentration is higher inside the cell than outside the cell.
Explanation:
In a neuron, sodium and potassium concentrations are maintained by the sodium-potassium exchange pump such that the sodium concentration is higher outside the cell than inside the cell and the potassium concentration is higher inside the cell than outside the cell.
What is sodium potassium pump?The sodium potassium pump contributes to the maintenance of osmotic equilibrium and membrane potential in cells. Sodium and potassium move in the contrast way of the concentration gradients.
The Na+ K+-ATPase pump establish and maintain a gradient of higher sodium concentrations extracellularly and higher potassium levels intracellularly.
The sodium-potassium pump is critical to the proper functioning of neurons. It aids in the maintenance of ionic concentrations both inside and outside the cell, allowing neurons to fire action potentials, which is the basis for electrical signaling within neurons.
The sodium-potassium exchange pump maintains sodium and potassium concentrations in neurons so that the sodium concentration is higher outside the cell than inside the cell and the potassium concentration is higher inside the cell than outside the cell.
Thus, this way, sodium and potassium concentrations are maintained by the sodium-potassium exchange pump in a neuron.

What are valence electrons?
Answer: : a single electron or one of two or more electrons in the outer shell of an atom that is responsible for the chemical properties of the atom.
Explanation:
Which are examples of active transport?
Select all that apply.
exocytosis
phagocytosis
diffusion
pinocytosis
Answer:
Exocytosis, phagocytosis, and pinocytosis
Explanation:
Active transport is when energy is used to move substances across the cellular membrane.
Exocytosis requires energy to remove materials from the cell; it is active.
Phagocytosis also requires energy; it is active.
Diffusion isn't active because it moves materials down their concentration gradient and therefore it doesn't require energy.
Pinocytosis is a form of endocytosis and requires energy; it is active.

What forms in the areas where oceanic plates diverge and new seafloor is created? (3 points)
Abyssal plains
Continental shelf
Continental slope
Mid-ocean ridge
Answer:
A mid ocean ridge is your answer
Explanation:Divergent boundaries in the middle of the ocean contribute to seafloor spreading. As plates made of oceanic crust pull apart, a crack in the ocean floor appears. Magma then oozes up from the mantle to fill in the space between the plates, forming a raised ridge called a mid-ocean ridge.
the answer is mid ocean ridge

In a forest community, a shelf fungus and a slug live on the side of a decaying tree trunk. The fungus digests and absorbs materials from the tree, while the slug eats algae growing on the outside of the trunk. These organisms do not compete with one another because they occupy
A. the same habitat, but different niches
B. the same niche, but different habitats
C. the same niche and the same habitat
D. different habitats and different niches
The shelf fungus and slug in the forest community do not compete with each other as they have the same habitat, but different niches. Thus, option A is correct.
What are habitat and niche?Habitat is defined as the place where the species resides while the niche is the role of the specific organisms or the species in that particular habitat or environment. The niche includes the impact of the species on the habitat.
The shelf fungus and the slug both live on the side of the tree and hence have the same habitat but the fungus takes minerals from the tree and the slug from the algae making them differ in the niche.
Therefore, the fungus and slug have the same habitat but different niches.

in the study of genetics the offspring of the p generation is referred to as the
Answer:
F1 Generation
Explanation:
In the study of genetics the offspring of the P generation is referred to as the F1 generation.
In the study of genetics, the offspring of the P generation are referred to as the F1 offspring, or first fillial offspring. Their genetic makeup depends on their parents.
What is inheritance?Inheritance explains how the genes from the parents pass down to the offspring. An example is when both parents are tall because they are purebred, then all the F1 offspring are tall.
The T is represented by tall, and the t is represented by short. TT is purebred tall, and tt is purebred short. When two parents (P generation) are heterozygous for tallness, such as Tt, each will produce gametes such as T and t. From these gametes, three types of individuals are formed, such as purebred tall (TT), heterozygous tall (Tt), and purebred short (tt). These are called F1 offspring.
Hence, in the study of genetics, the offspring of the P generation are referred to as the F1 offspring, or first fillial offspring.

where is dna found in eukaryotic cells? why is this important?
Answer:
nucleus and we need dna so we can figure out people in our past
Explanation:
In eukaryotic cells, DNA is present inside the nucleus of the cell. DNA is important because it codes for life processes, and it transfers to the next generations.
What is DNA?Three subunits, nitrogenous bases, hydrogen bonding, and a phosphorus backbone make up the double helix structure of DNA. It is a component of genetic material found in all living things.
Every organism has a unique strand of DNA. Although DNA is composed of the same components as those listed above, the bases are joined in a different order. Every organism's genetic makeup was altered as a result.
DNA is found inside the nucleus of the cell, and in prokaryotes, it is found in a coiled form in the center of the cell.
Therefore, the DNA is found in the cell's nucleus of eukaryotic cells. DNA is significant because it transmits to subsequent generations and codes for biological functions.
