(1)The cerebral cortex, also known as the cerebral mantle, is the outer layer of neural tissue of the cerebrum of the brain in humans and other mammals. The cerebral cortex mostly consists of the six-layered neocortex, with just 10% consisting of allocortex.

(2)The hypothalamus is a small region of the brain. It's located at the base of the brain, near the pituitary gland. While it's very small, the hypothalamus plays a crucial role in many important functions, including: releasing hormones. regulating body temperature.

(3) The brainstem (or brain stem) is the posterior stalk-like part of the brain that connects the cerebrum with the spinal cord. In the human brain the brainstem is composed of the midbrain, the pons, and the medulla oblongata Ten pairs of cranial nerves come from the brainstem.

(4)The spinal cord is a long, fragile tubelike structure that begins at the end of the brain stem and continues down almost to the bottom of the spine. The spinal cord consists of bundles of nerve axons forming pathways that carry incoming and outgoing messages between the brain and the rest of the body.

Answer:

Carbohydrate (monosaccharide)

Explanation:

Carbohydrates are one of the four biological molecules in nature. Carbohydrates are structurally composed of carbon, hydrogen and oxygen elements. However, these elements (C,H,O) are present in each carbohydrate in the ratio 1:2:1 respectively.

As stated in this question, glucose is an organic molecule made up of carbon, hydrogen and oxygen in the 1:2:1 proportion, hence, it is a CARBOHYDRATE. Since glucose possess one sugar component, it is classified as a MONOSACCHARIDE with a chemical formula C6H12O6.

Answer:

Having 20% cholesterol in a membrane would reduce the fluidity.

Explanation:

At high temperatures, cholesterol stabilizes the membrane and increases the melting point.

The plasma membrane is the layer that surrounds the cell and is composed of cholesterol and phospholipid. The presence of cholesterol reduces the fluidity and transition.

The plasma membrane separates the exterior and the interior of the cell and through a semi-permeable nature allows the transport of the molecules. It is composed of phospholipids and cholesterol molecules.

The phase transition of the membrane is known by the change in the rigidity as it starts free-flowing at a high temperature called transition temperature.

In the presence of cholesterol, the movement and the fluidity reduce as it interferes with the fatty acid chain and now requires more temperature to convert the rigid structure to become fluid.

Therefore, membrane-containing cholesterol requires more temperature to modify the fluidity as compared to phospholipids alone.

Answer:

c. a duplication of the C4 gene

Explanation:

Schizophrenia is a disease that affects the brain, which is characterized by an imbalance of neurotransmitters and the presence of damaged brain tissues. In humans, the Complement component 4 (C4) protein is found at the neurons (i.e., cell bodies, dendrites and axons), which are the most common brain cells, and neuronal synapses. Moreover, gene duplication can increase gene expression when repressive mechanisms (e.g., DNA methylation at promoter sites) capable of silencing the expression of the duplicated gene are lacking. Recently, it has been discovered that a chromosome rearrangement associated with a tandem duplication of a genomic region that contains a C4 gene may contribute to schizophrenia risk by increasing the expression of this gene​. In this example, a, b and d options are associated with a decrease in expression of the C4 gene, either by decreasing its transcription (options a and d) or by posttranscriptional mechanisms (option c).

Answer:

After S phase sister chromatids appear to share a common centromere.

Explanation:

The cells of the different organisms go through different periods during their life, each one characteristic and well differentiated. Before the mitosis process, during the S phase of the cell cycle, the chromosomes replicate, so that at the time of initiating cell division in humans, each of the 46 replicated chromosomes will have two chromatids joined by the centromere, each one of them represents a functional chromosome. Each sister chromatid of a chromosome secretes a daughter cell, as do the other 45, and together they will make up the diploid "cluster" of 46 chromosomes from the new cell. In other words, each chromosome is made up of two chromatids that come together at a point called the centromere. One chromatid contains a condensed chromatin molecule and the other has another identical chromatin molecule, the result of DNA replication, which is why we talk about a sister chromatid chromosome. Each chromatid has two arms of equal or different length.

Answer:

variable expressivity; incomplete penetrance

Explanation:

In genetics, variable expressivity refers to the fact that individuals having the same alleles/genes/genotype associated with a particular genetic condition may exhibit different clinical features of this condition. In general, variable expressivity is due to the combination of both genetic and environmental factors. An example of variable expressivity is the Marfan syndrome, where all individuals with this disorder have a dominant mutation in the FBN1 (fibrillin 1) gene and show different degrees of the same phenotype. Moreover, incomplete penetrance (also known as reduced penetrance) refers to the complete absence of a genetic trait or disease in individuals having alleles/genes/genotype associated with the condition. In consequence, individuals with incomplete penetrance do not develop features of the disease. An example of incomplete penetrance is given by those individuals with mutations in BRCA1/BRCA2 genes (associated with an increased risk of developing breast cancer) that do not develop cancer.

Answer:

0.0177

Explanation:

Cystic fibrosis is an autosomal recessive disease, thereby an individual must have both copies of the CFTR mutant alleles to have this disease. The Hardy-Weinberg equilibrium states that p² + 2pq + q² = 1, where p² represents the frequency of the homo-zygous dominant genotype (normal phenotype), q² represents the frequency of the homo-zygous recessive genotype (cystic fibrosis phenotype), and 2pq represents the frequency of the heterozygous genotype (individuals that carry one copy of the CFTR mutant allele). Moreover, under Hardy-Weinberg equilibrium, the sum of the dominant 'p' allele frequency and the recessive 'q' allele frequency is equal to 1. In this case, we can observe that the frequency of the homo-zygous recessive condition for cystic fibrosis (q²) is 1/3200. In consequence, the frequency of the recessive allele for cystic fibrosis can be calculated as follows:

1/3200 = q² (have two CFTR mutant alleles) >>  

q = √ (1/3200) = 1/56.57 >>

- Frequency of the CFTR allele q = 1/56.57 = 0.0177  

- Frequency of the dominant 'normal' allele p = 1 - q = 1 - 0.0177 = 0.9823

Answer:

The first bar increases in length as compared to the second bar.

Explanation:

The length of the bar of control cages in graph increases because the number of bees per colony increases while on the other hand, the length of the bar of the cage that is exposed to fungicides decreases because the bees are negatively affected from the application of fungicides. They act abnormal in behaviour and adversely affected the reproduction of bees that greatly affected its population.

Answer:

True.

Explanation:

Extinction vortex is a model used by scientists to understand extinction dynamics within a community. This model allows scientists to assess and understand how a population can become highly vulnerable to elements of its habitat, becoming increasingly apt for extinction. According to this model, any organism is capable of extinction, as all are susceptible to having a gene pool that will not allow its survival, regardless of the environment.

Answer:

Oxygen is carried by blood to all the cells of the body in the form of haemoglobin.​

Explanation:

Oxygen is carried in the blood in two forms:

(1) dissolved in plasma and red blood cells water (about 2% of the total)

(2) reversibly bound to haemoglobin (about 98% of the total).

Haemoglobin is a protein in the red blood cells and carries oxygen around our bodies. At the same time, carbon dioxide that is dissolved in the blood comes out of the capillaries back into the air sacs, ready to be breathed out.

Answer:

623 monomers

Explanation:

In a dehydration synthesis reaction, one water molecule is removed for every bond that is created between 2 monomers.

Linking 3 monomers together would remove 2 water molecules.

Following this pattern, the number of water molecules removed will always be one less than the number of monomers that were joined together.

So, if 622 water molecules were removed, then 623 monomers were joined together.

The answer is 623 monomers.

Answer and Explanation:

The microorganisms such as bacteria and fungi are basically composed of biological macromolecules (lipids, proteins, polysaccharides). As the temperature increases, the structure of proteins is disrupted and they lose their function. For example, enzymes that catalyze biological reactions are inactivated.

Therefore, wet heat sterilization is a process in which the material is heated during a certain time at a certain high temperature to destroy the microorganisms by producing the denaturation of structural proteins and enzymes.

Pinto beans are added to tacos, burritos, and soups that are high in fiber.

The body is unable to digest fiber, which is a form of carbohydrate. While fiber cannot be converted into glucose, the sugar that results from the breakdown of most carbs, fiber travels through the body undigested.

The solubility, viscosity, and fermentability of dietary fibers, which have an impact on how they are metabolized by the body, can be used to classify them in general. Dietary fibers have a wide range of chemical compositions.

Fibre comes in two varieties: soluble and insoluble. Both are crucial for good health, digestion, and illness prevention. Thus, Pinto beans are added to tacos, burritos, and soups that are high in fiber.
