Libido is the basic emotional and psychic energy of life, is believed to be constituted by life instincts. This is according to the psychoanalytic theory of sigmund freud,
In psychoanalytic theory, the energy produced by sexual and survival instincts is referred to as libido. Sigmund Freud claimed that the libido is the motivation behind all conduct and is a component of the id. Despite the obviously sexual connotations that the word "libido" now has, Freud used it to refer to all psychic energy, not simply sexual energy.
According to Freud, the only aspect of personality that exists from birth is the id. He proposed that the id was a source of unconscious, primal energy. The id seeks pleasure and expects that its desires be met right away. The id is the motivation behind our desires and impulsive actions.

Which of the following is not cause by human interaction with the earth system
Answer:
Answer: C. mountain building
Air pollution, water pollution and deforestation are caused by human interaction with the earth system. Air, water and forests are abiotic (non-living) factors of the environment on which human population is dependent upon. Release of pollutants in the air and water due to human activities causes pollution. Forests are removed in order to derive resources like wood, medicines and for urban development hence, causes deforestation. Mountain building is a nature induced process and is not caused by human interactions with the earth system. Mountain formation is a geological process, which is caused by large scale movement of the earth's crust. Mountains are formed by folding and faulting of the earth's crust and due to volcanic activity.

When the blood glucose level rises after a meal, the first organ to respond is the?
When the blood glucose level rises after a meal, the first organ to respond is the pancreas.
Insulin is a hormone produced by the body to regulate blood sugar levels. When the glucose level rises in the blood, the insulin secreted causes glucose to be transported to the cells from the blood. In the cells, the extra glucose is used accordingly and the cells of the liver and muscles can store it as glucagon.
Hence, when the blood glucose level rises after a meal, the pancreas makes insulin to balance the blood sugar levels.
Other options, such as the stomach, is not correct as the stomach is involved in the digestion of food and does not lower blood sugar levels.

Why are some bacteria, such as those of the genera mycobacterium and nocardia, not effectively stained with the gram stain?
Answer:
Some bacteria, such as those of the genera mycobacterium and nocardia, not effectively stained with the gram stain because they have too much peptidoglycan in their cell walls.
Explanation:
Across most types of bacteria, the cytoplasmic membranes is encased in a hard material called peptidoglycan. It helps maintain cell shape all across the life cycle and shields bacterial cells against environmental stress. The production of peptidoglycan has a significant role in controlling bacterial cell division. The bacterial cell wall's peptidoglycan plays a structural role by providing structural support and balancing the cytoplasm's osmolarity. Additionally, peptidoglycan participates in binary fission throughout bacterial cell division. Christian Gram, a microbiologist, developed a test in 1884 which might identify whether a bacterium possessed a strong, mesh-like membrane known as peptidoglycan. Numerous bacteriophages, eukaryotic, and bacteria all generate peptididoglycan hydrolases.

How does the bottleneck effect undermine the effort of conservation biologists who are trying to save species nearing extinction?.
The bottleneck effect undermines the effort of conservation biologists who are trying to protect species nearing extinction by events such as floods, earthquakes, human habitat devastation, and drought can cause a population to drastically decline.
The bottleneck effect can undermine the conservation of efforts of biologists who saves species near extinction when the population’s size is drastically reduced due to environmental factors including starvation, earthquakes, floods, fires, disease, and droughts as well as human behaviors like speculative killing, widespread violence or planned to cull, and human population control. As a result, a smaller population with less genetic diversity is left to transmit genes to future generations of offspring through sexual reproduction.
Such events can reduce the variation in a population’s gene pool. Genetic diversity continues to be reduced, only gradually rising over time when random mutations take place or only when gene flow from another group happens.

In expressing a mammalian gene in e. coli, the most formidable obstacle is the presence of:_________
1) introns
2) exons
3) repressors
4) enhancers
5) integrators
Option 1: In expressing the mammalian genes in e.coli, the most formidable obstacle is Introns.
Introns are the nucleotide sequences that do not directly code for proteins. They reside in the genes of an organisms and are generally removed during transcription of an RNA molecule.
Our DNA comprises exons and introns, where exons are coding parts while introns are non-coding parts. Introns get stuck in between which leads to stopping the coding of DNA because it does not form any kind of protein. These are like gap which is not coded for protein. So to avoid this obstacle we replace it with exons by the process of splicing. This is because exons form proteins and thus can participate in DNA coding (as DNA is responsible for the synthesis of proteins). These are found in all creatures and all types of genes.

Iodophors and chloramines are similar in that they are both halogen-containing compounds that __________.
Iodophors and chloramines are similar because they are both halogen-containing compounds that slowly release their active ingredients because they release their active ingredients more slowly than the elemental forms of these halogens.
As we know, Iodophor is an iodine-containing solution used in the dairy and brewing industries as a sanitizer. Chloramines are disinfectants and are used to kill germs in drinking water. As both the compound used to kill bacteria, both contain halogen compounds which equalize the numbers of the hydrogen atoms.
Therefore, Iodophors and chloramines, both compounds, release their active ingredients slower because of their chemical properties, as halogen takes time to equalize the number of hydrogen atoms. Thus, Iodophors and chloramines are very active and effective and widely used by industries but are slower.

What is the hybridization of the central atom in the xenon tetrafluoride molecule?
The central atom has 6 electron pairs out of which two are lone pair electrons. The hybridization in Xenon is sp3 d2 because there is a migration of two electrons of p to d orbital which results in the formation of a sigma bond with F.
What is meant by hybridization?Whenever two atomic orbitals in a molecule merge to generate a hybrid orbital, the energy of the orbitals of the single atoms is redistributed to give orbitals of equivalent energy. Hybridization is the name of this procedure. In the hybridization process, atomic orbitals with similar energies are mixed together; this often includes the fusion of two s orbitals, two p orbitals, or the mixing of an s orbital with a p orbital or a d orbital.
Hybrid orbitals are the novel orbitals that result from this process. However, hybrid orbitals are also very helpful in describing the geometry of molecules and the characteristics of atomic bonds. Let's immediately examine the example of an atom of carbon. This atom creates four single bonds in which three valence-shell p orbitals and one valence-shell s orbital combine.
The result of this combination is the creation of four comparable sp3 mixes. Around the carbon, which is bound to four distinct atoms, they will be arranged in a tetrahedral pattern.
Therefore, the molecule has sp3 d2 hybridization.

Debris (Hydrogen and helium) from the big bang gravitationally clumped together, and frequently these clumps got big enough to start fusion in their centers and form stars.
What is big bang theory?
The Big Bang theory explains how the cosmos expanded from a highly dense and hot starting condition. The evolution of the observable cosmos from the earliest known times up to its later large-scale shape is explained by this prevalent cosmological model. A wide range of observable phenomena, such as the quantity of light elements, the cosmic microwave background (CMB) radiation, and large-scale structure, are all thoroughly explained by the model.
Eventually, the large gaseous balls fuse hydrogen into heavier elements, which causes them to become stars. The periodic table's iron is created when stars combine light elements to create heavier ones.
The remaining elements of the periodic table are created as a result of the stars exploding, producing white dwarfs that explode, or forming neutron stars that collide and explode. The remaining hydrogen gas is now "contaminated" by this other material, and some of it forms an accretion disk in which planets form when it compresses under gravity.

What condition will increase the diffusion of molecules, such as neurotransmitters?
An increase in the number of neurotransmitters exocytosed by the presynaptic axon will increase the diffusion of molecules such as neurotransmitters.
what are neurotransmitters?
Any of a group of chemical agents released by neurons (nerve cells) to stimulate surrounding neurons, muscle cells, or gland cells allows impulses to be transmitted from one cell to the next throughout the nervous system. This is known as a neurotransmitter, also known as a chemical transmitter or chemical messenger.
These neurotransmitters are stored in synaptic vesicles of the axon terminals and are released during transmission of impulses from one neuron to another.
Neurotransmitter molecules are instantly destroyed by enzymes in the synaptic cleft after being released and binding to postsynaptic receptors; they are also absorbed by receptors in the presynaptic membrane and recycled.
Hence, if they are released in large amounts from the synaptic vesicles their diffusion will increase automatically.
