There are several "facts" about the human brain that neuroscientists have grown accustomed to: it has 100 billion neurons and 10- to 50-fold more glial cells than expected for its size; it makes up an astounding 20% of the entire body; it is the largest brain among primates and animals in general.
According to the researchers, any brain activity without L5p neurons must be unconscious as consciousness depends on these neurons. Nobody is certain how awareness, or the state of consciousness, and its contents, such as ideas and experiences, are related. Researchers have now put up a sophisticated solution: a direct structural connection. In the human brain, there are about 86 billion neurons.

Proteins are polymers produced by linking together amino acids, where the amino group of one will react with the acid group of another. What type of functional group is produced
The Functional group produced is Amide.
The most typical way to make amides is by reacting an acid chloride with ammonia, a 1o amine, or a 2o amine. In a similar procedure, an amide can be created by reacting an amine with a carboxylic acid using a coupling agent like DCC. An acid anhydride and an amine can be combined to create simple amides. Finally, a carboxylic acid and an amine can directly react to generate amides.
However, because to the severity of the circumstances, this response is not frequently used. Because the Y group of an amide's nitrogen-containing atom has a weak ability to act as a leaving group, amides are comparatively inert to nucleophilic acyl substitutions.

The model explains that two lipidic layers compose the cell membrane, with proteins and glucans embedded in between.
Lipids are arranged with their hydrophilic heads facing the exterior and the interior of the cells, while their hydrophobic tails are against each other, constituting the internal part of the membrane.
Two types of proteins compose the membrane,
• Integral proteins, permanently associated with the membrane.
• Periferic proteins, in the internal or external surface.
Proteins and lipids are distributed asymmetrically in the membrane. Proteins have a determined orientation, which is essential to accomplish their functions.
Membranes are fluid, meaning their molecules can move by
• Lateral diffusion in the same layer →This is passive diffusion.
• Transversally to the other layer → infrequent
• Rotational diffusion → rotation of the molecule.

b. does not affect cells.
c. always causes cells to shrink.
d. does not have anything to do with solute concentration.
Tonicity is the comparison of relative concentrations of two solutions, separated by a selectively permeable membrane.
Tonicity is the capacity of an extracellular solution to cause water to osmotically enter or exit a cell. Tonicity differs from osmolarity in that it considers both the relative solute concentrations and the permeability of the cell membrane to those solutes.When describing whether a solution would induce water to move into or out of a cell, three terms—hypertonic, hypotonic, and isotonic—are used:A cell will lose volume if it is immersed in a hypertonic solution because there will be a net flow of water out of the cell.
A cell will increase volume if it is immersed in a hypotonic solution because there will be a net flow of water entering the cell.
If a cell is immersed in an isotonic solution, there won't be any net water inflow or outflow, and the volume of the cell will stay constant.

Sex-linked genes are transmitted with the sex chromosomes. The combination of alleles that are involved in the inheritance of a sex-linked trait are alleles carried on X and Y chromosomes. Option C)
What is a sex-linked gene?
Genes are physically located and arranged in the chromosomes. Each chromosome contains several genes that vary in length and code for different traits. So, all chromosomes are different, except for the homologous ones.
In mammals, sex is determined by a pair of sex chromosomes, X and Y.
Females are represented by the combination of two X chromosomes, XXMales are represented by the combination of an X chromosome with a Y chromosome, XY.When talking about sex-linked genes, we refer to genes located in one of the sex chromosomes. In general, genes are linked to the X chromosome.
Being linked to one of the sex chromosomes means that these genes, and their corresponding alleles, will only be inherited together with the chromosome.
In the case of X-linked genes, a male that inherits the X chromosome from a heterozygous female can express either the dominant or the recessive trait, depending on which allele it got from the mother.
According to this framework, the correct answer is C) alleles that are carried on X and Y chromosomes.

Loss of dna sequences at the ends of chromosomes in the ________ region may cause cell senescence.
Loss of DNA sequences at the ends of chromosomes in the telomere region may cause cell senescence.
A chromosome's end contains a stretch of repeating DNA sequences known as a telomere. Chromosome ends are shielded from fraying or tangling by telomeres. The telomeres get a little bit shorter every time a cell divides. They eventually get so short that the cell can no longer successfully divide, and the cell then perishes.With age, telomere length decreases. The health and lifespan of an individual are impacted by the progressive shortening of telomeres, which causes senescence, apoptosis, or oncogenic transformation of somatic cells. Reduced survival and higher illness incidence have been linked to shorter telomeres.Telomeres shrink by 50–200 bp with each somatic cell division cycle as a result of inadequate synthesis of the lagging strand during DNA replication.learn more about telomeres here: https://brainly.com/question/13784303

The relationship between the caterpillars and milkweed is characterized by - for the milkweed and + for the caterpillar
The monarch butterfly can only survive if it feeds on milkweed during its whole life cycle. Because monarch butterfly larvae, also known as caterpillars, can only feed on milkweed, this species of butterfly is also known as the "milkweed butterfly."The female monarch butterfly lay her eggs on the bottom of the milkweed leaves, which will offer the developing larvae protection as they grow. The big leaves function similarly to umbrellas, protecting the eggs from the excessive heat of the summer sun and providing cover from the heavy downpours. In addition, the leaves provide a wonderful place to conceal oneself from any predators that might be interested in eating the eggs before the larva hatches. As soon as the eggs hatch, the larvae will begin to feed on the leaves of the milkweed plants. For the first few days of their lives, they will consume food continuously, day and night. The milkweed provides the young caterpillars with more than just food while they develop. Milkweed offers a one-of-a-kind defence against predators to both the monarch butterfly larvae and the adult butterflies. The larvae consume a significant proportion of the milkweed plant's dangerous compounds since the milkweed plant itself contains poisonous elements. As a result, the monarch butterfly themselves become poisonous.
