The oceanic crust is formed from the volcanic vents that erupt under water. The rocks that are formed from these eruptions are mafic, because they are compose magnesium and iron. Examples of mafic rocks are basalt and gabbro.

The Earth is made up of several layers. The deeper you go, the more heat and pressure. It gets really hot at the core because of different factors. One of them is the outer core and the inner core. The outer core flows around the solid core, which creates friction, thus creates heat. The outer core is also responsible for the electromagnetic property of the Earth.

Because seismic waves behave differently when they encounter different materials, geologists are able to use this to determine the different states of the layers beneath the Earth's surface. It helps them to determine whether the layer is molten, semi-molten or even solid.

The core is not the Earth's outer skin. The layer described is actually the CRUST. The core is the deepest layer of the Earth. It is solid and mostly made up of iron. The crust on the other hand is the outermost layer, and it is the layer that we live on.

A particular protein largely lacks both secondary and tertiary structure. which factor, if any, is mainly responsible for the re

NemiM [27]

Entropy, is mainly responsible for the resting state of this protein.

Hydrogen bonds, disulfide bonds, and dipole-dipole interactions produce the complicated folding styles seen in secondary and tertiary structure. however, if a protein does not have these elements of structure, it'll undertake a kingdom in which its entropy is maximized.

Secondary shape is determined through hydrogen bonding within the amino acid chain backbone. Tertiary structure is the entire protein's form, decided Entropy Interplay and hydrophobic forces. The tertiary shape of a protein is the 3 dimensional shape of the protein. Disulfide bonds, hydrogen bonds, ionic bonds, and hydrophobic interactions all affect the form a protein takes.

The nonpolar amino acids have formed the nonpolar center of the protein, weak van der Waals forces stabilize the protein. furthermore, hydrogen bonds and ionic interactions between the polar, charged amino acids make a contribution to the tertiary structure.

A. Entropy

B. Hydrogen bonds between amino acid residues

C. Dipole-dipole interactions

D. None of the above

Give two reasonsthat may account for the continuous firing of a<br> PostsynapticNeuron.

lyudmila [28]

Answer:

1.Continuous diffusion of negatively charged ions into the postsynaptic neurons , <u>which leads to continuous reversal of charges (hyperpolarization) and therefore continuous firing of action potential</u>

2. Inhibition of hydrolytic enzymes e.g (acetycholinesterase) that metabolize activities of cholinergic neurotransmitters e,g acetycholine at post synaptic cleft. leading to firing of action potential.

Explanation:

Neuron whose dendrites transmits action potential to the neuromuscular junction is called presynaptic neuron. While neuron that transmit action potential away from the neuronal synaptic junction, or from the neuromuscular junction to the cell body of adjacent neuron or to effectors (gland and muscles) are called post synaptic neuron.

The more negatively charged ions that diffused into the post synsptic neuron, the more depolarization, and the greater the frequency of action potential produced

The inhibition of activities of hydrolytic enzyme which metabolize cholinergic neurotransmitter leads to continuous excitatory activities of cholinergic neurotransmitters on the receptors at the postsynaptic neuron, and the more action potential

Name the plant tissue

sp2606 [1]

The different types of plant tissues are:

1. Meristematic tissues - It is of three types: Apical, Lateral and lntercalary.

2. Permanent Tissue - It of two types: Simple and Complex tissues. Simple tissues are of three types Parenchyma, Collenchyma and Sclerenchyma.

Complex tissues are of two types - Xylem and Phloem.
