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:
The suprachiasmatic nuclei enable the nervous system to respond to daily light/dark alterations through their stimulation of melatonin.
Explanation:
Melatonin is a hormone produced naturally by the body. Its function is to regulate the body's circadian cycle. This hormone is stimulated and begins to act by changing between a light environment and a dark environment. This stimulation interacts with the suprachiasmatic nuclei making the nervous system understand this change and luminosity of the environment and respond to the action of melatonin.
All of the following factors contribute to the differences in complex trait risk predictions between different laboratories, EXCEPT ____________. differing methods of combining risk from multiple genetic variants selection of different genetic variants for risk determination different assessments of environmental factors genotyping of different variants
Answer:
different assessments of environmental factors
Explanation:
In humans, for predicting the future phenotype of any individual, the PSR is used.
A trait may be defined as the state of a character that is a distinct variation of the phenotypic characteristic of any organism.
The following factors contributes to the differences in the complex trait risk predictions in the different laboratories :
-- differing methods of the combining risk from the multiple genetic variants.
-- genotyping of the different variants.
-- selection of the different genetic variants for such risk determination.
Thus the factor which does not contribute is :

Normally, this region is imprinted in the sperm, but not the egg. This means that the DNA on the ____________ copy of the chromosome will be methylated at the imprinting center, while the DNA on the ____________copy of the chromosome will not be methylated in this region.
Answer: The DNA on the paternal copy of the chromosome will be methylated at the imprinting center, while the DNA on the maternal copy of the chromosome will not be methylated in this region.
Explanation:
Chromosomes are DNA structures associated with proteins such as histones. They are found in the nucleus of cells and contain genetic information for the development and functioning of an organism. Human beings are diploid, meaning that they possess two copies of each of the 23 chromosomes (a total of 46).
Gametes, which are sex cells such as the sperm (produced by the male) and the egg (produced by the female) that are haploid. This means that they possess only one chromosome of each pair. During fertilization, a male gamete fuses with a female gamete to generate a zygote, which will give rise to a new human being. This new individual will possess half of the genetic material from its father and half from its mother. Thus having a total of 46 chromosomes, 23 from each parent.
Genetic imprinting modulates gene expression by chemical modification of DNA and/or modification of chromatin structure. Often, genetic imprinting causes a gene to be expressed only on the chromosome inherited from one of the parents. One example of imprinting is DNA methylation, which is a process by which methyl groups are added to DNA. Methylation modifies DNA function when found in the promoter gene, repressing gene transcription. This means that a methylated gene will not be expressed, that is, it will not produce a protein encoded by that gene. So, if a region of DNA is imprinted in the sperm cell, the paternal chromosome inherited from this sperm will be methylated in the genes of the offspring. And the offspring will only express the maternal copy inherited, which will not be methylated.
The following statement is incorrect as stated "Pesticides create pesticide resistance in mosquitoes." Rewrite this sentence so that it is a more accurate statement of what actually occurs when pesticides are used. Why is this concept important to know in trying to control outbreaks of mosquito transmitted diseases such as eastern equine encephalitis (also known as Triple E)?
Answer:
Mosquitoes usually become resistant to pyrethroids through the mutation of a sodium channel gene that controls the movement of ions across cell membranes. Mutations in a single gene are enough to make mosquitoes almost completely resistant to the level of pyrethroids used in insecticides.

Select one:
a. Industry and agriculture both overuse surface water resources.
b. Industry and agriculture both overuse groundwater resources.
c. Industry overuses surface water and agriculture overuses
groundwater.
O d. Industry overuses groundwater and agriculture overuses
surface water
Water is a source that is used for various purposes. The industry overuses the surface water, whereas agriculture overuses the groundwater leading to water scarcity. Thus, option C is correct.
What is water scarcity?Water scarcity is the unavailability of water or can be said as a shortage of water through the regular supplies due to the overuse and excess waste of these resources.
The lack of sufficient amount of water that has been said to be not equal to the demand is a major issue that affects every organism globally. It can lead to economic decline as there will be drought.
Water is used in various fields including the industries for machines and other works, and also in agriculture fields to grow plants and crops. The industry uses the water present on the surfaces like lakes, and rivers, while crops need the water from the wells.
Therefore, option C. the industry and agriculture overuse water.

How will you isolate DNA from a pure fungal culture
Answer:
Explanation:
There are several ways of isolating DNA from a pure fungal culture but you can use the CTAB method.
In this method, genomic DNA can be extracted.
First of all, the cell walls of fungal mycelia can first be broken down by grinding it using glass rods or you can use or liquid nitrogen. Place it in a plate. You can now CTAB extraction buffer , then incubate at 65°C, then let it undergo purification with phenol:chloroform:isoamyl alcohol 25: 24: 1 and carry out precipitation with isopropanol . Then the DNA can be extracted and then dissolved in 50 μl of pure water.
3. A bacterial isolate from a urine specimen was grown in culture, Gram stained, and then tested for its ability to ferment sugars and hydrolyze various subtrates. What approach to bacterial identification is this an example of
Answer:
Phenotypic approach for bacterial identification
Explanation:
Bacterial identification can be done by conventional methods, which are based on phenotypical characteristics. These methods are much affordable and reasonable.
Phenotypical identification is based on bacteria´s observable characteristics, such as their morphology, development, and biochemical/metabolic properties.
It is important to consider that these methods do not provide absolute certainty. They can only indicate the genera or species to which the bacteria under study may belong.
Some primary evidence is usually used for fast bacteria identification:
Gram staining, morphology, growth at different media or different incubation atmospheres, glucose fermentation, spores production, motion, aerobiosis/anaerobiosis, among others.Knowing that the bacteria in the exposed example was isolated and grown in culture, then Gram-stained and tested for biochemical reaction, we can assume that the approach for its identification is phenotypic.

Answer:
Somatic: Skeletal muscle activation VoluntaryPrincipally involved with movement "of" the body.Autonomic: Can be excitatory or inhibitory on the target organ. Principally involved with the movement of materials through the body. Intestinal smooth muscle activation. Sweat gland activation Lacrimal gland activation Piloerector muscle Involuntary activation.Explanation:
We can divide the nervous system into the central nervous system, which consists of the brain and spinal cord, and the peripheral nervous system, which consists of all the nerves that are throughout the body carrying information from and to the central nervous system.
We divide the peripheral nervous system into the somatic nervous system and the autonomic nervous system.
The somatic nervous system is the conscious one, that is to say, that we know and control what it does. It is voluntary. It has motor and sensory neurons that carry information to and from the central nervous system. The somatic nervous system is the one that makes us move our muscles to do an action.
The autonomic nervous system is involuntary. In other words, we can not control it consciously. It is the one that controls glands, organs, and smooth muscle, like the one that surrounds the digestive tract to move the food. As we can not consciously control it, this system can work exiting or inhibiting an organ depending on the situation.
The peripheral nervous system is simply divided into 2 types, which are the somatic nervous system and the autonomic nervous system.

Which of the following statements depend on the absolute dating of events?
Answer:
The statement that depends on the absolute dating of events is this: The oldest Earth rocks are 3.9 billion years old. Absolute dating is the method of determining the specific date of an archaeological or paleontological artifact.
Answer:
It says that the oldest Earth rocks are 3.9 trillion years old, and they depend on the absolute adaptations of events. Absolute dating is the mechanism through which an archaeological or paleontological artifact determines a particular date.
120 million years ago, birds diverged from the related dinosaurs.3.9 billion years old is the oldest Earth rock.Explanation:
Geologists must often know the material age they encounter. They use absolute data systems, sometimes referred to as numerical dates, to provide rocks with the actual date or date range for years to come. It differs from relative dates, which only time-consuming geologic events.
In contrast to the relative date, the absolute date represents a certain age or range which places occurrences among events without age being measured. The most absolute ages for rocks are reached by radiometric methods. Minerals are radioactive in rocks like geological watches.

why are electrons in an atom involved in bonding
Answer:
The valence electrons have a role in the bonding of two atoms. The nuclei of each atom are drawn together by their attraction to the valence electrons of the other atom. As the atoms are drawn together by their attractions, electrons from each atom are drawn to the nuclei of both atoms, where they are "shared."
