Explanation:
In eastern gray squirrels, Sciurus carolinensis, the allele for black fur (B) is dominant to the allele for gray fur (b) . In a particular population of gray squirrels, 64% have black fur and 36% have gray fur. A researcher calculated the allelic frequencies to be B = 0.6 and b = 0.4. Which of the following could best explain the increase in the frequency of the Ballele in the population after five years?
a. The frequency of the B allele increased because it is the dominant allele.
b. The frequency of the Ballele increased because squirrels with gray fur exhibited greater fitness.
c. The frequency of the B allele increased due to the selective pressures of the environment.
d. The frequency of the Ballele increased because black squirrels randomly mate with other eastern gray squirrels.
Answer:
The answer to the given question is C.
Explanation:
Natural selection:
The population contains both superior as well as inferior organisms where natural resources are limiting so it will cause competition between organisms. As a result of competition, it will select superiors, and inferiors are deleted and they are given reproductive advantages. Due to this reproductive advantage new population emerges. It is more suitable for the environment.
Natural selection divides into three parts that are directional, disruptive, and stabilizing selection.
This is an example of natural selection. Environmental conditions create pressure on the individuals and if they can survive and become fittest, their number increases in the population. This is according to Darwin's theory in the struggle for existence. These organisms survived as the fittest organisms to match climatic conditions.
Stabilizing selection: This operates when features coincide with the optimal environmental conditions and the organisms survive in a population. Stabilizing selection pressures do not promote evolutionary change but tend to maintain stability within the population from generation to generation.
In the beginning, directional selection - the organism develops characters to survive in response to gradual changes in the environmental conditions. It works on a range of phenotypes existing within a population and exerts selection pressure which moves the mean phenotype to one phenotypic extreme. When the mean phenotype overlaps with the new optimum environmental conditions, stabilizing selection will take over.
Why water alone is not sufficient to remove oil spots? Explain!
Problematic fat molecules called triglycerides (oil) do not dissolve in water because of their hydrophobic (water-fearing) nature. The water can push around the oil and make more of a mess. Cooking oil is different then motor oil and require different treatment.

An organism has the following characteristics: cell wall, heterotrophic, unicellular, and prokaryote. What kingdom does
it belong in?
• Animalia
• Protista
• Plantae
•Eubacteria
Answer:
The correct answer is - Eubacteria.
Explanation:
Eubacteria is a kingdom that comes under prokaryotic organisms. These organisms have many characteristic features that are as follows:
Body Structure: Eubacteria are single-celled organisms with a cell wall outside of the cell to protect them.
Food: Eubacteria are both auto- and heterotrophic which means they can be either autotrophic, they use both chemical synthesis and photosynthesis.
Animals lack the cell wall, planate are autotrophic and protists are eukaryotic organisms so the correct answer is eubacteria.

fungsionalisme adalah?
Answer:
Teori adalah suatu pendapat bagaimana dan kenapa sebuah fakta terjadi. (Macionis, 1997:15). Sedangkan Scupin dan De Corse (1995)mendefinisikan teori adalah kumpulan hipotesis yang tidak berhubungan yang menawarkan penjelasan secara umum untuk fenomena natural atau sosial. Salah satu teori Antropologi adalah fungsionalisme.
Teori fungsionalisme adalah teori dominan dalam antropologi. Teori ini memandang budaya sebagai satu kesatuan, dan mencoba untuk menjelaskan bagaimana hubungan antara bagian-bagian masyarakat yang tercipta dan bagaimana bagian ini fungsional (bermakan memiliki konsekuensi yang menguntungkan pada individu dan masyarakat) dan disfungsional (bermakna memiliki konsekuensi negatif). Teori ini memandang masyarakat sebagai sistem yang kompleks yang mana bagian tersebut bekerja bersama untuk mempromosikan solidaritas dan stabilitas; ini menandakan bahwa kehidupan sosia kita dituntun berdasar pada struktur sosial, yang pola perilaku sosialnya secara relatif stabil (Macionis, 1997)
Seluruh struktur sosial berkntribusi pada operasi masyarakat. Dua antropolog inggris terkemuka Radcliff Brown dan Bronslaw Malinowski, menggambarkan dua standar teori: Struktural fungsionalisme, yang menekankan pada keunggulan dari masyarakat dan menyusun para individu, dan bagaimana berbagai macam elemenfungsi struktur sosial untuk memelihara permintaan sosial dan keseimbangan. Dan Psikologi strukturalisme, yang mana menekankan pada kbutuhan individual untuk bertemu dengan masyarakat.
Kelemahan teori fungsional adalah gagalnya menjelaskan kenapa masyarakat itu berbeda atau justru memiliki kesamaan. Ontropolog fungsionalisme menganggap dunia tertib, memberi sedikit perhatian atau bahkan tidak memberi perhatian pada kompetisi dan konflik (Howard dan Dunaif-Hattis, 1992). Teori ini tidak berhubungan dengan sejarah, mengabaikan proses sejarah. (Scupin dan De Corse, 1995) teori ini juga tidak dapat menjelaskan perubahan sosial dan budaya, sebagaimana ia dulu memandang masyarakat sebagai sesuatu yang stabil dan tetap. meskipun memiliki kelemahan, teori fungsionalisme mempengaruhi perjanjian besar penelitian empirik dalam antropologi.

A. Coats guard hairs to improve their informance
B. Usually opens up into a hair follicle
C. Simple, coiled, tubular glands
D. Secretes earwax
E. Coats the scalp hair with oil
F. Blockage and infection can cause pimples
1. Sebaceous
2. Ceruminous
Answer:
A. Ceruminous
B. Sebaceous
C. Ceruminous
D. Ceruminous
E. Sebaceous
F. Sebaceous
Explanation:
Ceruminous glands are modified sweat glands located subcutaneously in the cartilaginous two-thirds of the external auditory canal. Ceruminous glands produce together with sebaceous glands the cerumen (i.e. earwax), which protects the ear canal against physical damage and/or microbial infections. On the other hand, sebaceous glands are glands in the skin that secrete sebum, an oily, waxy substance that lubricates the hair and skin of mammals. These glands (sebaceous) are affected by sex hormones like testosterone that enlarges the glands due to the increased cell proliferation rate and estradiol, which reduces the size of the glands due to the accelerated cell breakdown. Sebaceous glands are holocrine glands in which secretions are produced in the cytoplasm of the cells and then they are released by the rupture of the plasma membrane, while ceruminous glands are apocrine glands where the accumulated secretion is pinched off with a portion of the cell.

A traumatic injury to the inferior angle of the mandible severs the hypoglossal nerve. Which of the following muscles would be affected?
a. Geniohyoid
b. Mylohyoid
c. Genioglossus
d. Stylohyoid
The muscle that would be affected is the Genioglossus. That is option C.
The hypoglossal nerve is the also known as cranial nerve XII.
This nerve arises from the nuclei in the medulla oblongata.
They supply:
the muscles of the tonguemuscles surrounding the hyoid bone andcontribute to swallowing and speech.The muscles of the tongue includes
genioglossus, hyoglossusstyloglossus, and palatoglossusThe genioglossus is a flat triangular muscle that forms the base by which the tongue is attached.
Since the hypoglossal nerve supplies the the tongue muscle (genioglossus), it would be must affected when mandible severs the hypoglossal nerve.

What assumption regarding the population is necessary for making an interval estimate for the population mean?
Answer:
The assumption regarding the population which is necessary for making an interval estimate for the population mean is that:
a. We assume that the population has a normal distribution.
b. We assume that the central limit theorem applies.
Explanation:
The assumption regarding the population which is necessary for making an interval estimate for the population mean is that:
a. We assume that the population has a normal distribution.
b. We assume that the central limit theorem applies.
A normal distribution describes how the values of a variable are distributed. It is a probability distribution that is symmetrical about the central value or the mean, i.e. 50% of data are found to the left and right of the mean respectively. Most of the data are clustered around the mean, i.e. they occur or are found near the mean than far away from the mean. The graph form of a normal distribution will appear as a bell curve. In a normal distribution, mean = mode = median.
The Central Limit Theorem states that irrespective of the underlying distribution of a sample, when a variable does not follow a normal distribution, repeated random samples from the population will give sample means they are normally distributed. This means that the sampling distribution of the sample means approaches a normal distribution as the sample size gets larger.
