one of the most common chromosomal disorders is ________ in which a baby has ________________.
Answer:
One of the most common chromosomal disorders is Down syndrome. Down syndrome happens when abnormal cell division results in extra genetic material from chromosome 21, too few chromosomes, or part of a chromosome may be missing. The difficulties of Down syndrome include hearing and vision weakness, weak auditory memory, fine motor skill impairment, short attention span with distractibility. Having Down syndrome can increase the risk of developing Alzheimer's disease. Having down syndrome can be associated with other health conditions such as ear infections, dental problems, endocrine problems, and seizures.

TRANSCRIPTION AND TRANSLATION
Genes provide information for building proteins. They don’t however directly create proteins. The production of proteins is completed through two processes: transcription and translation.
Transcription and translation take the information in DNA and use it to produce proteins. Transcription uses a strand of DNA as a template to build a molecule called RNA.
The RNA molecule is the link between DNA and the production of proteins. During translation, the RNA molecule created in the transcription process delivers information from the DNA to the protein-building machines.
DNA → RNA → Protein
DNA and RNA are similar molecules and are both built from smaller molecules called nucleotides. Proteins are made from a sequence of amino acids rather than nucleotides. Transcription and translation are the two processes that convert a sequence of nucleotides from DNA into a sequence of amino acids to build the desired protein.
These two processes are essential for life. They are found in all organisms – eukaryotic and prokaryotic. Converting genetic information into proteins has kept life in existence for billions of years.
DNA and RNA
RNA and DNA are very similar molecules. They are both nucleic acids (one of the four molecules of life), they are both built on a foundation of nucleotides and they both contain four nitrogenous bases that pair up.
A strand of DNA contains a chain of connecting nucleotides. Each nucleotide contains a sugar, and a nitrogenous base and a phosphate group. There is a total of four different nitrogenous bases in DNA: adenine (A), thymine (T), guanine (G), and cytosine (C).
A strand of DNA is almost always found bonded to another strand of DNA in a double helix. Two strands of DNA are bonded together by their nitrogenous bases. The bases form what are called ‘base pairs’ where adenine and thymine bond together and guanine and cytosine bond together.
Adenine and thymine are complementary bases and do not bond with the guanine and cytosine. Guanine and cytosine only bond with each other and not adenine or thymine.
There are a couple of key differences between the structure of DNA and RNA molecules. They contain different sugars. DNA has a deoxyribose sugar while RNA has a ribose sugar.

Explanation:
electromagnetic waves: Electromagnetic waves or EM waves are waves that are created as a result of vibrations between an electric field and a magnetic field. In other words, EM waves are composed of oscillating magnetic and electric fields.
radio waves: Radio waves are a type of electromagnetic radiation best-known for their use in communication technologies, such as television, mobile phones and radios. These devices receive radio waves and convert them to mechanical vibrations in the speaker to create sound waves.
microwaves: Microwave is a form of electromagnetic radiation with wavelengths ranging from about one meter to one millimeter corresponding to frequencies between 300 MHz and 300 GHz respectively.
infrared: Infrared (IR) light is used by electrical heaters, cookers for cooking food, short-range communications like remote controls, optical fibres, security systems and thermal imaging cameras which detect people in the dark.
visible ray: The visible spectrum is the portion of the electromagnetic spectrum that is visible to the human eye. Electromagnetic radiation in this range of wavelengths is called visible light or simply light. A typical human eye will respond to wavelengths from about 380 to about 750 nanometers
ultraviolet:UV radiation is widely used in industrial processes and in medical and dental practices for a variety of purposes, such as killing bacteria, creating fluorescent effects, curing inks and resins, phototherapy and suntanning. Different UV wavelengths and intensities are used for different purposes
xray:An X-ray, or, much less commonly, X-radiation, is a penetrating form of high-energy electromagnetic radiation. Most X-rays have a wavelength ranging from 10 picometers to 10 nanometers, corresponding to frequencies in the range 30 petahertz to 30 exahertz (30×1015 Hz to 30×1018 Hz)
gama ray :A gamma ray, also known as gamma radiation, is a penetrating form of electromagnetic radiation arising from the radioactive decay of atomic nuclei.

Explain how fitness can change the allele frequency of a population. PLZ no link
Answer:
Natural selection can cause microevolution (change in allele frequencies).
Explanation:
With fitness-increasing alleles becoming more common in the population.
Fitness can affect the survival and reproduction rates of individuals with different alleles, leading to differential contribution to the next generation and changes in the frequency of these alleles in the population.
What is fitness?Fitness is a measure of the reproductive success of an individual within a population. The fittest individuals are those that are most successful at passing their genes on to the next generation. When the environment changes, the selective pressures on a population also change. This can lead to changes in the relative fitness of different individuals, and thus changes in the allele frequencies of a population over time.
For example, if a population of birds lives on an island with small seeds, those birds with small beaks may be more fit than those with larger beaks. This is because they are better adapted to the environment and can more easily obtain food. Over time, the frequency of the small-beaked allele will increase in the population, while the frequency of the large-beaked allele will decrease.
Thus, fitness can drive changes in the allele frequency of a population over time by favoring those individuals with alleles that are better adapted to the environment.

How would a protein transit through a cell?
Answer:
How would a protein transit through a cell?Explanation:
Protein cargo moves from the ER to the Golgi, is modified within the Golgi, and is then sent to various destinations in the cell, including the lysosomes and the cell surface. The Golgi processes proteins made by the endoplasmic reticulum (ER) before sending them out to the cell.
6. Identify the type of climate data that has the longest data range. 1. microscopic organism 2. data sediment core 3. data tree ring 4. data ice core data
Complementing data, taken from different sources such as tree rings, sediments, and ice, provides significant information about global climatic changes. However, ice core data has the longest data range. (4) is correct.
-------------------------------
Ice core data refers to the information obtained from a sample of ice taken from a glacier or a mountain.
Information kept in the ice is mostly about gases concentration at different moments though time.
Analysis of retained gases in Antarctic ice, through perforations of over 2000 meters deep, has allowed knowing the CO₂ atmospheric concentrations and other gases involved in the greenhouse effect for at least 150,000 years.
These concentrations have varied in the temporal scale of glaciation, showing low concentrations during glacial periods with low temperature and relatively high concentrations during interglacial periods with high temperature.
Between these two periods, abrupt variations in temperature and gas concentration are detected, meaning that changes in CO₂ cause changes in temperature.
The increase in CO₂ is a highly significant component in global climatic change and possibly the best documented.
This information is the best paleoclimatic documents.
Complementing it with marine sediments core and data tree rings makes it possible to know about the principal traits of terrestrial weather in the lasts 420,000 years, practically four glacial-interglacial cycles.
