The Human blood type is determined by the presence or absence of specific antigens on the surface of red blood cells polygenic inheritance involves the contribution of multiple genes to a single trait, which is not the case for human blood type determination. D
The genetics of blood types involves both codominance and multiple alleles.
Codominance refers to a situation where both alleles of a gene are expressed simultaneously and equally in the phenotype.
In the case of blood type, there are three alleles involved: A, B, and O.
Alleles A and B are codominant, meaning that if an individual inherits both A and B alleles, both antigens will be present on their red blood cells. This results in blood type AB.
Multiple alleles refer to the existence of more than two alternative forms of a gene in a population.
In the case of blood type, individuals can have blood type A (AA or AO genotype), blood type B (BB or BO genotype), blood type AB (AB genotype), or blood type O (OO genotype).
The A and B alleles are dominant over the O allele, which is recessive.
Therefore, the combination of codominance and multiple alleles explains the inheritance patterns of human blood types.
This system allows for the expression of both A and B antigens (codominance) while accommodating the presence of multiple alleles (A, B, and O) in the population.
It is important to note that blood type inheritance is not an example of incomplete dominance or polygenic inheritance.
Incomplete dominance refers to a situation where neither allele is completely dominant, resulting in an intermediate phenotype.
Therefore, human blood type is an example of both codominance (expressing multiple alleles simultaneously) and multiple alleles (more than two alternative forms of a gene exist within a population).

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.

The Law of Independent Assortment states that alternate versions of genes cause variation in inherited characteristics. The correct option is D.
What is the Law of Independent Assortment?The law of Independent Assortment is given by Gregor Mendel. He was a scientist and botanist who gave very useful discoveries in the field of hereditary.
The law of Independent Assortment states that the gene from both parents for the same traits does not overlap, They were present independently, and they are the reason for the variation.
Variation is the different characters present in an organism. The recessive gene and the dominant gene are the two types of alleles. The dominant allele is shown in the organism.

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=

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.
