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.
Which of the following is correct?
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.

Which of the following events contributes to the termination of a signal generated by the binding of a ligand to a receptor tyrosine kinase? Only one answer is correct
1. Phosphatases hydrolyze key phosphorylated residues.
2. Kinases hydrolyze key phosphorylated residues.
3. Kinases phosphorylate key residues.
4. The receptor tyrosine kinase dimerizes.
5. GTPase removes a phosphoryl group from GTP.
6. Phosphatases phosphorylate key residues.
Answer:
1. Phosphatases hydrolyze key phosphorylated residues.
Explanation:
Receptor Tyrosine Kinases (RTKs) are high-affinity transmembrane protein receptors that bind to a wide variety of ligands (e.g., growth factors, cytokines, hormones). These receptors (RTKs) have a transmembrane domain and therefore these proteins act as membrane receptors, as well as exhibit catalytic activity. The intracellular C terminal region of RTKs contains catalytic domains responsible for both autophosphorylation and tyrosine phosphorylation of their protein substrates. Moreover, Protein Tyrosine Phosphatase (PTPs) are critical enzymes that remove phosphate groups from tyrosine residues in different substrates (including RTKs), thereby regulating key signaling pathways such as cell proliferation, cell differentiation, and cell-cell adhesion.

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.

If the entire mRNA sequence for a polypeptide was AUGUACUCGCGACCGUAA, how many amino acids does the polypeptide have
Answer:
5 amino acids
Explanation:
The process of translation involves synthesizing a sequence of amino acids from a mRNA template. The mRNA molecule is read in a group of three nucleotides called CODONS. A codon specifies or codes for an amino acid.
In the question, a mRNA sequence was given as follows: AUGUACUCGCGACCGUAA. From this sequence comprising of 6 codons, 5 possible amino acids will be contained in the polypeptide encoded by this mRNA molecule as the last codon (UAA) is a STOP codon.

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.
SOMATIC
Voluntary principally involved with movement "of" body skeletal muscles activation
AUTONOMIC
Involuntary lacrimal gland activation intestinal smooth muscle activation principally involved with movement "through" body sweat gland activation arrector pili activation can be excitatory or inhibitory on target organThe peripheral nervous system (PNS) is the simply known as the division of the nervous system that has all the nerves that is found outside of the central nervous system (CNS).

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.

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."
