What is the best way to ensure that results of a study are generalizable to a population?
By making sure to use as many participants as possible
By making sure the results are significant
By making sure to use an equal number of men and women
By using random assignment
By using a random selection of people in that population
The best way to ensure that results of a study are generalizable to a population is by using a random selection of people in that population
The goal of every research experiment is to obtain results that are generalizable to a whole population.
This is achieved by the method of random selection. In random selection, members of the of the population are selected in such a way that is representative of the entire population. If for instance, I want to study a school having six classes which comprises of boys and girls. There are 700 students in the school and I need only 180 students to participate in a study whose results will be extrapolated to all the 700 students. I can decide to randomly select 15 boys and 15 girls from each class to participate in the study. This is an example of random selection.
In this way, the results obtained from the study is reflective of the whole population even though only a sample of the population actually participated in the study.

The CT reveals several issues with the cranial structure, one of which might be in the cribriform plate but the image isn't well defined. What non-invasive test can you do to test if the cribriform plate is severely damaged? Why?
The non-invasive test that can be used to test if the cribriform plate is severely damaged is called the pledget study.
CRIBRIFORM PLATE is the part of the ethmoid bone that forms the nasal cavity.
The olfactory nerve which is part of the cranial nerves passes through the small opening found in the cribriform plate.
A damage to the cribriform plate leads to cerebrospinal fluid (CSF) leak which usually comes out from the nose and ears.
Therefore to test if the cribriform plate is severely damaged, the pledget study is performed.
Pledget study is a non-invasive method of diagnosing a CSF leak.
To perform this test,
Cotton pads called Pledgets are placed in the nostrils.If the leaking fluid contains CSF it will be detected.The presence of CSF shows that there is damage to the cribriform plate.
This method is non invasive because it doesn't require the breaking or opening of any part of the body.

Explanation:
The statement is false, it should read, "Learned behavior is not inherited. It is developed through observation and experience and allows animals to adapt to changes in the environment."
What is learned behavior?Learned behaviors are those behaviors or characteristics that we learn from observing other people, learning and reading, and our experiences. It is the best type of characteristic of humans because learning just by observation is very efficient.
This behavior can not be inherited by another person because it is not in our genes. The behavior can be acquired by nature and the learning ability of a human, not inheritance. The genetic qualities are only inherited.

Given the gene sequence GGACCGTCGATCTTC, which of the following choices would represent an inversion mutation?
A. CCACCGTCGATCTTC
B. GGACTCGATCTTC
C. GGACCGTCGATCTTC
D. GGACCGTCGATCCTT
Reset Selection
ASAP
Answer:
D. GGACCGTCGATCCTT
Explanation:
Mutation refers to any change in the nucleotide sequence of a gene. Mutation can be of different types depending on how it occurs. According to the question, an INVERSION mutation is a type of mutation in which a segment of a gene gets broken off and reattached in another way on the same DNA. Hence, the only change in inversion mutation is the arrangement of the nucleotide bases on the gene.
Considering the nucleotide sequence: GGACCGTCGATCTTC, the sequence that describes an occurrence of inversion mutation is: GGACCGTCGATCCTT because the segment TTC in the original sequence has been rearranged as CTT in the mutated sequence.

1. How are wavelength, frequency, and energy related to each other?
Answer:
wavelength: the distance between successive crests of a wave
frequency: the rate per second of a vibration constituting a wave, either in a material (as in sound waves), or in an electromagnetic field (as in radio waves and light)
electromagnetic energy is used for wifi, cell phones, microwave ovens etc.
the electromagnetic spectrum includes radio waves, microwaves, infrared radiation, visisble light, ultraviolet, xrays and gamma rays
the only part we can see is visible light
visible light can be characterised by the colours of the rainbow
the longest wavelength is red and the shortest is violet
when combined, the colour is perceived as white or beige
Answer:
Just as wavelength and frequency are related to light, they are also related to energy. The shorter the wavelengths and higher the frequency corresponds with greater energy. So the longer the wavelengths and lower the frequency results in lower energy.
Explanation:
WAVELENGTH=

Part iii. What adaptations are associated with a frugivory diet? Give an example of a primate that has this diet.
Part iv. What adaptations are associated with a folivory diet? Give an example of a primate that has this diet.
Part v. What adaptations are associated with vertical clinging and leaping? Give an example of a primate that practices this form of locomotion.
The examples that you need are 1-Gummivory: marmoset, tamarins; 2-Frugivores: spider monkey, ray-bellied night monkey (owl monkey); 3-Folivory: howler monkey, leaf monkey, colobine; and 4-Vertical clinging and leaping: lemurs and tarsiers
A gummivore is an animal (in this case, a primate) with a feeding strategy that depends on the sap or gum from trees. It is a type of diet that consists primarily of exudates. Some adaptations observed in these species include: 1-specialized anterior teeth in order to stab bark; 2-well-developed claws for clinging to trees
Frugivores primates have a feeding strategy mainly based on raw fruits. Some adaptations observed in these species include 1-low rounded molar cusps and 2-broad incisors.
Folivore primates (also called leaf-eating monkeys) have a feeding strategy mainly based on leaves. Some adaptations observed in these species include 1-narrow incisors, 2-broad molars (high shearing crests), 3-thin enamel molars.
Vertical clinging and leaping is an arboreal locomotor pattern practiced by lemurs and tarsiers. These animals push off from one vertical support with their hindlimbs to land on another vertical support. Some adaptations observed in these species include 1-hips, knees, feet, arms, and tails that facilitate climbing and leaping, 2-large hip extensor muscles and 3-specialized minor muscles.
