which of the following viewed the earth as younger than a million years old: a. darwin b. cloud c. hutton d. ussher
Answers
The one who viewed the Earth as younger than a million years old is Ussher
Who was Ussher?
James Ussher was an Irish prelate, archbishop, and theologian who was born in 1581 and died in 1656.
Ussher is best known for his chronology of the universe, which he used to calculate the exact moment of creation. According to his calculations, the Earth was created on October 23, 4004 BC at 9:00 AM. He made these calculations based on biblical genealogies. This aligned with the literal interpretation of the Bible prevalent during that time. Furthermore, he estimated that the earth was only a few thousand years old at the time.
It is to be noted however that after the scientific advancements, there have been numerous pieces of evidence that have been provided to prove that Earth is approximately 4.5 billion years old.

A study was conducted to determine if smoking cigars is associated with tongue cancer. Of the 500 individuals with tongue cancer, 450 were cigar smokers; of the 1,000 without tongue cancer, 450 were cigar smokers.
a) Create a 2x2 table
b) How many people smoked cigars and did not have tongue cancer?
c) How many people did not smoke cigars and did not have tongue cancer?
d) Calculate the odds ratio
E) Interpret the odds ratio
Answers
a) The 2x2 table for the study:
Tongue Cancer No Tongue Cancer
Cigar Smokers 450 450
Non-Smokers 50 550
b) Number of people who smoked cigars and did not have tongue cancer: 450.
c) Number of people who did not smoke cigars and did not have tongue cancer: 550.
d) The odds ratio is 11.
e) Interpretation: Cigar smokers are 11 times more likely to develop tongue cancer compared to non-smokers.
a) The 2x2 table for the study is as follows:
Tongue Cancer No Tongue Cancer
Cigar Smokers 450 450
Non-Smokers 50 550
b) The number of people who smoked cigars and did not have tongue cancer is 450.
c) The number of people who did not smoke cigars and did not have tongue cancer is 550.
d) To calculate the odds ratio, we use the formula: (ad)/(bc), where a is the number of cigar smokers with tongue cancer, b is the number of non-smokers with tongue cancer, c is the number of cigar smokers without tongue cancer, and d is the number of non-smokers without tongue cancer. In this case, the odds ratio is:
(450 * 550) / (50 * 450) = 550 / 50 = 11
e) The odds ratio of 11 indicates that individuals who smoke cigars are 11 times more likely to develop tongue cancer compared to those who do not smoke cigars. This suggests a strong association between cigar smoking and tongue cancer. It is important to note that the odds ratio only indicates the strength of association and does not establish causation. Other factors, such as lifestyle, genetics, and other smoking habits, may also contribute to the development of tongue cancer. Further research and analysis would be required to determine the causal relationship between cigar smoking and tongue cancer.

How does melanoma affect the functions of the skin?
How does jaundice affect the functions of the skin?
Answers
Answer:
Melanoma is a type of skin cancer that develops in certain skin cells called melanocytes. These are the cells that make the pigment (melanin) that colors your skin. When exposed to UV radiation, such as sunlight, the melanocytes make more pigment, causing the skin to darken or tan. Melanoma starts in cells in the skin called melanocytes. These cells are in the deep layer of the epidermis between the layer of basal cells.
Jaundice causes the skin and the whites of the eyes to turn yellow. The higher the bilirubin level, the yellower the skin. Severe jaundice usually also causes itching and bile. Bile is fluid secreted by the liver.

QUESTION 21. Transsexual males, who frequently take supplemental estrogen to look more feminine, score higher on measures of ______ than males with unaltered levels of estrogen.
a. visual-spatial ability
b. mathematical ability.
c. aggression.
d. verbal ability
Answers
Transsexual males, who frequently take supplemental estrogen to look more feminine, score higher on measures of A visual-spatial ability than males with unaltered levels of estrogen.
Transsexual males who take supplemental estrogen to look more feminine score higher on measures of visual-spatial ability than males with unaltered levels of estrogen. This is because estrogen is known to enhance certain cognitive abilities, such as visual-spatial processing and memory. However, it is important to note that this does not mean that all transsexual males will score higher on these measures, as individual differences in cognitive abilities exist within all populations.
In summary, transsexual males who take supplemental estrogen to look more feminine tend to score higher on measures of visual-spatial ability than males with unaltered levels of estrogen due to the cognitive enhancing effects of estrogen.

After Frida stops exercising, she continues to breathe heavily. What is most likely occurring in her body?
Answers
Answer:
Strenuous exercise has caused her body to be in oxygen debt, and she is breathing hard while lactate is transported to the liver. This is a result of anaerobic respiration
Explanation: Anaerobic cellular respiration occurs and due to the lack of oxygen she takes deeper breaths. That way, there's oxygen in the muscles while respiration occurs.
Answer:
Frida is lacking air, or oxygen, because of her exercising. She starts panting quickly to take in air faster and make up for the oxygen loss. The heart beats hard during exercise, and needs oxygen to return to a normal pace

estions A woman cannot become pregnant if she is already pregnant. Describe the hormonal Interactions that prevent a pregnant woman from becoming pregnant again [2 marks]
Answers
When a woman is already pregnant, hormonal interactions involve the suppression of ovulation and changes in the uterine lining to make it less receptive to implantation.
During pregnancy, the body produces high levels of hormones, particularly progesterone and estrogen. These hormones play crucial roles in maintaining the pregnancy and preventing further ovulation.
Progesterone suppresses the release of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) from the pituitary gland, which are responsible for initiating ovulation. Without the surge of FSH and LH, the ovaries do not release another egg, making it unlikely for a woman to become pregnant again during her pregnancy.
Additionally, the hormonal changes during pregnancy cause modifications in the uterine lining. The lining becomes thicker and develops a mucus plug that seals the cervix. These changes create an environment that is less favorable for the implantation of a fertilized egg. The thickened lining and mucus plug act as physical barriers, preventing the attachment of another embryo to the uterine wall.
Overall, the hormonal interactions during pregnancy work together to suppress ovulation and alter the uterine environment, making it highly unlikely for a woman to conceive again while already pregnant.
These natural mechanisms help to ensure the proper development and progression of the existing pregnancy without the complications of multiple pregnancies occurring simultaneously.

when wild plant and animal populations are logged, fished, or hunted, only the oldest or largest individuals tend to be taken. many of the commercially important species are long lived and are slow to begin reproducing. which of these results is least likely if harvesting is not regulated carefully and exploitation is intense?
Answers
There will be fewer elderly people in the population, and comparatively more young people.
Effect A population growth rate that is excessively high among elderly people may experience a sudden fall as reproduction slows or ends. Yet, if only a small portion of the elderly population is removed, younger people will have access to more resources, which may boost their chances of surviving and reproducing as well as the population's rate of growth.These density-independent causes include nutritional or food scarcity, environmental contaminants, and harsh weather, including seasonal patterns like the monsoon. In addition, catastrophes like fires and storms can have an effect on population increase.Immigration may have a greater impact on population growth than birth rates in areas that are still being colonized.For more information on population growth kindly visit to

The information which is provided is insufficient to determine the uncertainty in the measurements done by Sandy.
The correct option is option d.
Based on the information which is provided, it is not possible to accurately determine the uncertainty of Sandy's measurement without additional context or knowledge about the measuring instrument's precision or the method used.
Uncertainty in measurements basically depends on factors such as instrument precision, measurement technique, and environmental conditions. To determine the uncertainty, one needs to consider factors beyond the reported value itself. Without specific information about these factors, it is not feasible to determine the uncertainty with certainty.

Answers
Answer:
1. Verdadero
2. Falso
3. Falso
4. Falso
5. Verdadero
Explanation:
Los seres humanos, como así también la mayoría de los mamíferos, poseen dos cromosomas sexuales: un cromosoma X y un cromosoma Y. Las hembras poseen 2 cromosomas X (un cromosoma X es heredado de la madre y el otro cromosoma X es heredado del padre); mientras que los hombres tienen un cromosoma X y un cromosoma Y (el cromosoma X es heredado de la madre, mientras que el cromosoma Y es heredado del padre). La hemofilia es una enfermedad recesiva monogénica ligada al cromosoma X, la cual está caracterizada por cuadros hemorrágicos causados por el déficit parcial y/o total de factores de coagulación. Los hombres expresan el fenotipo recesivo con mayor frecuencia que las mujeres para aquellos genes que se encuentran en el cromosoma X y poseen un mecanismo de herencia recesivo, esto debido a que los hombres sólo poseen una copia del alelo ligado al X (lo que hace que el alelo recesivo se exprese con mayor frecuencia en el fenotipo). De este modo, los hombres manifiestan hemofilia con mayor frecuencia que las mujeres porque en mujeres el gen recesivo necesita la presencia de dos copias del alelo defectuoso recesivo para que se exprese en el fenotipo hemofílico (es decir, las mujeres heterocigotas son portadoras de un alelo defectuoso pero no expresan la condición en el fenotipo), mientras que en los hombres la presencia de un sólo alelo defectuoso localizado en su único cromosoma X es suficiente para la expresión del fenotipo recesivo. En hombres, los genes ligados al cromosoma X son siempre heredados de la madre (los hombres heredan del padre el cromosoma Y). Finalmente, la herencia de caracteres ligados al cromosoma Y es muy rara porque los genes localizados en la región diferencial del cromosoma Y son escasos y estos genes solamente pueden ser trasmitidos de padres a hijos varones (ya que se encuentran en el cromosoma Y).

Mendel's law of independent assortment states that the alleles of two or more different genes get sorted into gametes independently of one another. The allele a gamete receives for one gene does not influence the allele received for another gene.
Explanation:
Mendel’s law of independent assortment states that genes do not influence each other with regard to the sorting of alleles into gametes: every possible combination of alleles for every gene is equally likely to occur.
