Explanation:
Analicen el cariotipo humano y den dos ejemplos de pares de cromosomas metacéntricos, dos ejemplos de pares telocéntricos y dos ejemplos de pares acrocéntricos.
Analyze the human karyotype and give two examples of pairs of metacentric chromosomes, two examples of telocentric pairs, and two examples of acrocentric pairs.
Answer: The test that is conducted to evaluate and identity the shape,size and number of chromosomes in cells of organism is called the Karyotype.
Metacentic chromosomes are X - shaped chromosomes. They have centromere at the middle, which makes the arms of the chromosomes equal in length. Therefore any type of chromosomes with equal length of arms is said to be Metacentic. Thus chromosomes on position 1,13, 16 , 19 and 20 are examples.
When a pair of chromosomes showed a regular segregation at anaphase of meiosis, they are said to be telocentric. They are type of chromosomes in which the centromere are located at the terminal ends of the chromosomes, with the telemeres extending from theses ends.Hence during segregation, the ends of telocentric chromosomes are orientated towards the poles of the cells. example is the alphabets ''i'' shaped chromosomes in mice and 29 pairs autosomes in Angora goats.
When the centromere is located in such a way that one arm lenght of a chromosomes is longer than the other, then this is called acrocentric. Example is chromosome 21 of down syndrome.others are 13, 14, 15, 22, and Y-chromosomes.

Businesses can perform and fund research studies, which potentially creates bias.
Scientific journals have a long history of publishing questionable research.
Government funding of research studies has the potential to create bias.
Poor research could potentially impact the health and welfare of the public.
Answer:
Poor research could potentially impact the health and welfare of the public.
Explanation:
Scientific studies are generally believed to be based on thorough research. This implies that members of the public always trust scientific publications and rely on same as a source of accurate and trustworthy information.
Science, being empirical in nature is believed to eliminate bias in its research and reportage of studies. Scientific research publications is often a source of information for field practitioners in diverse disciplines as well as the general public.
Poor research will mislead a large section of the public, both professionals in that field as well as laymen. This poor research could potentially impact the health and well being of members of the public negatively because they may be led to believe false information which can be disastrous. This is the reason why ethical guidelines are needed for the way scientific information is communicated.

What did you include in your response? Medications can be tested on cell cultures instead of being injected into patients unnecessarily. Cancer cells continue to grow in the cultures uncontrollably allowing scientists to test multiple medications on the cancer cells. Specific treatments that are shown to fight the growth of cancer cells in the culture can be used on patients. Cultures are safer to use than injections of unneeded medications into patients.
Answer:
The statements are correct.
Explanation:
Cell culture is a technique widely used in molecular biology where cell lines are grown in controlled conditions, thus allowing to make experiments and to test compounds that may result useful to treat diverse diseases, including cancer.
Immortalized cell lines are characterized for their ability to proliferate indefinitely which are derived from oncogenic tissues. In cancer research, these lines are used as models to test different drugs and to study cellular mechanisms associated with cancer progression including, among others, proliferation, invasiveness, vascularization, etc. In addition, the mechanisms associated with the death of cancer cells such as, for instance, apoptosis, may also be studied by using immortalized lines.

Which scenario causes gene flow
Answer: Migration is one way that genes are transferred from one population to another.
Explanation: Gene flow is caused by a significant change in the population of individuals due to the addition of other individuals whose alleles are slightly different from those of the existing individuals
Answer:
Introgression refers to gene flow from another taxon. While low levels of gene flow between species are not uncommon, it is a serious issue when an introduced invasive species hybridizes with a native species and overwhelms its genetic constitution (genetic swamping). This is a major threat in canids, ducks, fish and plants. For example, exotic rainbow trout introduced into the habitats of native cutthroat trout in the Western United States led to hybrid swarms that eventually overwhelmed the local species. Introgression is readily detected by molecular genetic and genomic methods.

write about the circulation of lymph for class 10
Answer:
The lymphatic system is a complex system of fluid drainage and transport, and immune response and disease resistance. Fluid that is forced out of the bloodstream during normal circulation is filtered through lymph nodes to remove bacteria, abnormal cells and other matter.
lymph circulation. The flow of lymph from the tissues into the lymphatic collecting system. ... It is collected into lymph capillaries, which carry the lymph to the larger lymph vessels. These converge to form one of two main trunks, the right lymphatic duct and the thoracic duct.
Understanding the lymphatic system's role in immune cell trafficking and immune responses, contribution to fat transport, distribution, metabolism and implication in the pathogenesis of chronic intestinal inflammation may provide the basis for new therapeutic strategies and improved quality-of life.

Explanation:
Read the information for transcription and then answer the question. Protein Synthesis Explain the process of transcription.
Answer:
Please find the explanation below
Explanation:
Transcription is the first process that occurs in protein synthesis. It involves the use of the stored information in the DNA molecule to synthesize a mRNA molecule.
Transcription, which occurs in the nucleus of eukaryotes and cytoplasm of prokaryotes, is catalyzed by an enzyme called RNA polymerase. RNA polymerase binds to the double-stranded DNA and begins to unwind it (Initiation). This unwinding causes the nucleotide bases to be exposed in order for the RNA polymerase enzyme to read.
The enzyme reads the bases of the DNA and begins to synthesize RNA nucleotides using the complementary base pairing rule (Elongation) i.e. Adenine base paired with Uracil base (RNA), and Guanine paired with Cytosine etc.
The single-stranded mRNA is released at the end of the transcription process (termination). This is basically what occurs in transcription.
The gene coding for the protein untwists and unzips.
RNA nucleotides form complimentary base pairs with the DNA bases.
Hydrogen bonds and sugar-phosphate bonds form and the mRNA strand is synthesized.
mRNA peels off the DNA and moves to the cytoplasm.

What is the main function of the structure labeled A?
It attracts insects and other animals.
It moves the pollen to the ovaries.
It catches pollen.
It produces pollen.
Answer:
D
Explanation:
I did the assignment
The main function of the structure labeled A is it produces pollen. Therefore, the correct option is D.
What is a pollen?Pollen is a microscopic, powdery substance produced by the male reproductive organs of seed plants. It is made up of cells that contain the male gametes (reproductive cells) and is responsible for fertilizing the female reproductive cells (ovules) to produce seeds.
Pollen is often carried from one plant to another by wind, insects, or other animals, where it can then come into contact with the female reproductive organs of a different plant.
If the pollen comes into contact with a receptive ovule, it can fertilize the ovule and produce a seed. Therefore, the correct option is D.

2. Assume that crossing over does not occur in the region of each chromosome that is associated with the centromere. You have 46 centromeric regions in each cell, 23 that are copies of the DNA in your mother’s egg and 23 that are copies of the DNA father’s sperm. Show your work for A,B,C a. For any given gamete, what is the probability that all the centromeric regions (chromosomes) will be copies of the same ones that you received from your mother? b. It has been estimated that the average person is heterozygous for at least 2,000 protein forming genes. How many different kinds of gametes is it theoretically possible for each person to produce? c. Considering the maternal and paternal origin of the centromeric regions alone, how many different kinds of gametes can you produce?
Answer:
See below
Explanation:
A. centromeric regions from mother in one cell: 23
total number of centromeric regions in one cell: 46
for every centromeric region that is inherited by the gamete, there is a 0.5 probability that it is from the mother. Hence, if all are from the mother:
0.5 ^ 23 = 1.19 x 10^(-7)
B. Heterozygous for 2000 genes means 4000 possible alleles.
2 ^ 4000 = 1.3 x 10^(1204)
C. 2 ^ 46 = 7.03 x 10^(13)
Explain how is it possible to have twins that are not identical
Fraternal (dizygotic) twins come from 2 different fertilized eggs that both grow in the mother's womb. They have different DNA (2 eggs from the mother, 2 sperm from the father) and are not identical, although they often look alike.
Identical (monozygotic) twins come from one fertilized egg that has split in two. These twins share the same DNA and are completely identical.
Identical twins develop from the same egg and sperm,the embryos split and form identical twins ,they are the same sex. But some are fraternal twins, they develop with two diferent sets of sperm and eggs by the same parents. They can be from diferent, this is like having diferent babies at the same time.
