Cheetahs face extinction pressure from climate change, hunting by humans, and habitat destruction, which is reducing the size of
their populations, Predict how these pressures have affected the genetic diversity of cheetahs.
Answers
Answer:
Genetic diversity has decreased due to inbreeding due to dwindling population size.
Cheetahs are facing great pressures, such as climate change, destruction of their habitat, and also hunting by humans that have greatly impacted their genetic diversity.
What are the causes of inbreeding in Cheetahs?Cheetahs have experienced a very declining rate of their populations due to destruction of their habitat, and also hunting by humans that has resulted in inbreeding in their populations and loss of genetic diversity.
Due to inbreeding, cheetahs have become more exposed to genetic disorders and vulnerable to diseases, and other threats.
Climate change has also posed a great threat to the declining population of cheetahs as it has affected their habitats and food resources. Climate change causes alteration in the temperature and rainfall pattern resulting in low availability of prey and water resources. Therefore, climate change leads to the malnutrition of cheetahs and making them more susceptible to severe disease.
Therefore, cheetahs are facing extinction due to climate change, habitat destruction, and hunting by humans.

In meiosis, 2 cells have been created at the end of telophase 1, halfway through the process. These cells are said to exist in a haploid state with a diploid number. Explain the statement. Support your answer clearly
Answers
Answer:
In some species, cells enter a brief interphase, or interkinesis, before entering meiosis II. Interkinesis lacks an S phase, so chromosomes are not duplicated. The two cells produced in meiosis I go through the events of meiosis II in synchrony. During meiosis II, the sister chromatids within the two daughter cells separate, forming four new haploid gametes. The mechanics of meiosis II is similar to mitosis, except that each dividing cell has only one set of homologous chromosomes. Therefore, each cell has half the number of sister chromatids to separate out as a diploid cell undergoing mitosis.
Prophase II
If the chromosomes decondensed in telophase I, they condense again. If nuclear envelopes were formed, they fragment into vesicles. The centrosomes that were duplicated during interkinesis move away from each other toward opposite poles, and new spindles are formed.
Prometaphase II
The nuclear envelopes are completely broken down, and the spindle is fully formed. Each sister chromatid forms an individual kinetochore that attaches to microtubules from opposite poles.
Metaphase II
The sister chromatids are maximally condensed and aligned at the equator of the cell.
Anaphase II
The sister chromatids are pulled apart by the kinetochore microtubules and move toward opposite poles. Non-kinetochore microtubules elongate the cell.

Figure 1. The process of chromosome alignment differs between meiosis I and meiosis II. In prometaphase I, microtubules attach to the fused kinetochores of homologous chromosomes, and the homologous chromosomes are arranged at the midpoint of the cell in metaphase I. In anaphase I, the homologous chromosomes are separated. In prometaphase II, microtubules attach to the kinetochores of sister chromatids, and the sister chromatids are arranged at the midpoint of the cells in metaphase II. In anaphase II, the sister chromatids are separated.
Telophase II and Cytokinesis
The chromosomes arrive at opposite poles and begin to decondense. Nuclear envelopes form around the chromosomes. Cytokinesis separates the two cells into four unique haploid cells. At this point, the newly formed nuclei are both haploid. The cells produced are genetically unique because of the random assortment of paternal and maternal homologs and because of the recombining of maternal and paternal segments of chromosomes (with their sets of genes) that occurs during crossover. The entire process of meiosis is outlined in Figure 2.

Figure 2. An animal cell with a diploid number of four (2n = 4) proceeds through the stages of meiosis to form four haploid daughter cells.
The immune system has both specific and nonspecific defenses against viral infections. Which statement describes a nonspecific response of the immune system in fighting viral infections?
A. T cells are produced to search out and destroy the viruses.
B. Memory B cells are activated to rapidly respond to the viral infection.
C. Plasma cells quickly replicate and release antibodies that bind to the viruses.
D. Virus-infected cells produce interferons that lead to the inhibition of viral replication
Answers
Answer:
C
Explanation:
I just did this same question
Virus-infected cells produce interferons that lead to the inhibition of viral replication and act as a nonspecific response of the immune system in fighting viral infections. Therefore, the correct statement is option D.
What are interferons?The immune system has two types of responses to viral infections: specific and nonspecific. Interferons are signaling molecules produced by virus-infected cells to activate antiviral defenses, such as apoptosis in infected cells. This refers to the nonspecific response of the immune system in fighting viral infections
Interferons function by alerting the immune system about the presence of a viral infection. Interferons can also stimulate the production of other immune cells, such as natural killer cells and macrophages to eliminate the infected cells.
Interferons have been also used to treat viral infections, such as hepatitis B, and are the nonspecific defenses that act as a first line of defense against viral infections.
Therefore, interferons that lead to the inhibition of viral replication are the nonspecific response of the immune system in fighting viral infections.

to overgrazing by farm animals. What catastrophic event is
most likely the cause the most weathering and erosion in the
least amount of time in this ecoregion?
1.Wildfire
2.Earthquake
3.Flood
4.Tornado
Answers
Answer:
3.Flood
Explanation:
Flood is the catastrophic event which is the main cause of the most weathering and erosion in the least amount of time in this ecoregion because there is no vegetation present in this region and the soil is vulnerable for erosion. Flash-flooding and rapid runoff are agents of erosion in the Trans-Pecos ecoregion of Texas whenever the rainfall occurs. Vegetative is very important for preventing soil erosion so the people of this region has to stop overgrazing in this area in order to avoid more erosion of the soil.

All three are X-linked, but each gene was found to contain repeats of a unique trinucleotide sequence.
Answers
Answer:
The correct answer is ''All three are caused by disparate genes, but each gene was found to contain repeats of a unique trinucleotide sequence.''
Explanation:
Four groups of trinucleotide repeats related to DNA expansion have been characterized in the human genome. CGGI GCC, CAGIGTC, CTGIGAC and recently GW CTT sequences. The CGGl GCC sequences are usually located in the noncoding regions of different genes and when expanded they associate with fragile sites on the chromosomes. The CAGIGTC repeats are part of the coding region and are related to different neurodegenerative disorders. You can try to make a classification depending on the unit that is repeated, having on one side a group that are caused by repeats of the CAG trinucleotide (cytosine, adenine, guanine). Huntington's disease (HD) is a progressive disorder of motor, cognitive and psychic function. The disease is inherited in an autosomal dominant manner, and is caused by the expansion of CAG trinucleotide repeats in exon 1 of the gene called huntingtin (HTT or IT-15). Unstable mutations have also been found in which the repeat unit does not is composed of three nucleotides, if not four, such as type 2 myotonic dystrophy, where the tetranucleotide CCTG repeats. Fragile X Syndrome consists of an abnormal expansion of the cytosine-guanine-guanine trinucleotide (CGG) in the FMR1 gene, which prevents intellectual disability and also influences the formation of connective tissue

Which principle allows us to assign dates to events on the geologic time scale?
faunal succession
extinction
radioactive decay
relative dating
Answers
The principle that allows us to assign dates to events on the geologic time scale is radioactive decay. Therefore, option (C) is correct.
What is radioactive decay?This theory is based on the observation that certain isotopes of elements are inherently unstable and, as a result, decay over time, giving rise to the formation of new isotopes or elements. Scientists are able to determine the age of a sample by measuring the ratio of parent to daughter isotopes in the sample. This, in turn, enables them to assign dates to events on the geologic time scale.
The method of determining the age of rocks, minerals, and other geological materials is known as radiometric dating, and it is utilized extensively in the field of geology as well as in other earth sciences.
