Answer:
The correct answer is -
a) 1/16
b) 1/64
c) 1/32
Explanation:
According to the law of independent assortment, each allele of a particular gene has equal chances of getting inherited into the gametes.
In a Mendelian cross of Aa x Aa would give;
AA = 1/4,
Aa = 2/4 and
aa = 1/4
The result of the cross between AaBb x AaBb would be 1/16 due to the fact that probability is still the same AA = 1/4, BB = 1/4 therefore, AABB = 1/16 = 1/4× 1/4.
Now based on this crossing the following:
AaBbCCDd x AabbCcDd.
Take each allele as individual
Aa x Aa would give; AA = 1/4, Aa = 2/4 and aa = 1/4
Bb x bb would give; BB = 1/2, bb = 1/2
CC x Cc would give; CC = 1/2, Cc = 1/2
Dd x Dd would give; DD = 1/4, Dd = 2/4 and dd = 1/4
Then the probability of progeny of the following would be:
a) the probability of AaBbCcDd = 2/4 x 1/2 x 1/2 x 2/4 = 1/16
b) the probability of aabbCCdd = 1/4 x 1/2 x 1/2 x 1/4 = 1/64
c) the probability of AabbCcDD = 2/4 x 1/2 x 1/2 x 1/4 = 1/32
The Big Five personality factors are five ranges of key personality traits. Describe each of the five factors. Then, describe how stable the traits are and how heritable they are.
Answer:
The big five traits are:
1- extraversion
2- neuroticism
3- agreeableness
4- openness
5- conscientiousness
Explanation:
The Big Five personality traits, also called the OCEAN model, is a widely accepted theory in psychology that states that personality can be reduced into 5 major factors: extraversion, agreeableness, openness, neuroticism and conscientiousness. Agreeableness refers to the manner in which one person treats other people. Conscientiousness refers to the ability to control impulses. Extraversion refers to the sociability level. Openness refers to the willingness for new experiences. Neuroticism refers to the person's emotional stability. These five traits are relatively stable during lifetime. Moreover, it has been shown that the Big Five traits are affected by both genetic factors (family) and cultural factors (education) in a proportion of 50:50. In consequence, approximately half of the differences observed between individuals result from genetic inheritance and half from environment.

Nondisjunction in Meiosis : Nondisjunction occurs when homologous chromosomes fail to separate during meiosis, resulting in an abnormal chromosome number
Why must transcription occur where DNA can be found?
because DNA can't leave
O because DNA polymerase is found there
O because ribosomes are in the nucleus
O because helicase unzips the DNA
Answer:
because DNA can't leave
Explanation:
Transcription must occur where deoxyribonucleic acid (DNA) can be found: A. because DNA can't leave.
What is transcription?Transcription can be defined as a biological process that typically involves re-writing the information contained within a deoxyribonucleic acid (DNA) into a ribonucleic acid (RNA) by enzyme RNA polymerase.
Generally, the Transcription of deoxyribonucleic acid (DNA) produces a single-stranded ribonucleic acid (RNA) molecule that is the same with the strand of DNA used as the template.
In conclusion, transcription must occur where deoxyribonucleic acid (DNA) can be found in living organisms because DNA can't leave.

You are given a sequence of DNA and told that it is human. You are asked to find out its identity and whether it has similarity to sequences in other organisms. Please describe the bioinformatics tool, the database, and the procedure you would use to find such information. Give two possible outcomes of your search.
Answer:
The summary of the question has been summarized throughout the explanation segment below.
Explanation:
BLAST seems to be the most commonly utilized sequencing correlation platform. BLAST seems to be a methodology as well as an operation for the comparison of primary physiological sequence data. Instead with BLAST, we're going enough to get some successfully predicted gene mutation new variant. Look for, racial identity percentage points and sometimes even E Value percentage points lookup pattern.This should start giving extensive information such as which life forms the component has been transcribed. And we'll get documentation about everything from the gene, exon, and so on., connection to the enzyme interpretation.
Crickets "chirp" by rubbing their wings or legs over each other. This phenomenon is known as stridulation. It is a means by which male crickets "call" to females to communicate their interest in mating. Frequency refers to the number of chirps that crickets produce during a period of time. Some have suggested that you can tell the temperature and the humidity based on how fast crickets chirp.
Required:
a. What is the effect of temperature on the frequency of cricket chirping? As the temperature rises, the cricket chirp occurs more rapidly therefore increasing.
b. What is the effect of humidity on the frequency of cricket chirping? As the humidity rises, the cricket chirp frequency occurs more rapidly therefore increasing.
Answer:
a. As the temperature rises, the cricket chirp occurs more rapidly therefore increasing. It is correct.
b. As the humidity rises, the cricket chirp frequency occurs more rapidly therefore increasing. It is incorrect. The increase in humidity does not affect the chirp frequency in crickets.
Explanation:
As temperature increases, the frequency of cricket chirp increases too. After listening to the audios, we can see that in the first audio, where the temperature is 14° Celcius, the frequency is 24 chirps in 15 seconds. In the second audio, with 19° Celcius, the frequency is 28 chirps in 15 seconds. In the last audio, where the temperature is 24° Celcius, the chirp's frequency is 34 chirps in 15 seconds. In conclusion, if the temperature increases, the chirps' frequency increases too.
As humidity increases, the frequency of the chirp does not. In the three audios, the number of chirps in 15 seconds was 20. We can conclude that humidity does not affect the frequency of chirps frequency.

The least numerous but the largest of the papillae are arranged as a V-shape on the posterior dorsal surface of the tongue. They contain the majority of taste buds and are called ________ papillae. papiform filiform fungiform vallate foliate
Answer:
The least numerous but the largest of the papillae are arranged as a V-shape on the posterior dorsal surface of the tongue. They contain the majority of taste buds and are called vallate papillae.
Explanation:
The shape, location and function of these taste buds make vallate papillae unique. First, they have a distinctive "v" shape, and most adults only have seven to twelve of these papillae, vallate papillae are the least numerous papillae, they are the recipients of the bitter taste. The vallate papillae are the largest and the most specialized, they are located on the back of the tongue, forming the lingual V, in a variable number from 7 to 12. The number of taste buds depends on age, presenting around 270 in the newborn and descending approximately one hundred in individuals older than 75 years. These buttons are located in the crypts or grooves that form the papillae, mainly on their internal face (the annular groove is observed between the papilla and the edge of the calyx), in whose edges the extremities of the taste corpuscles stand out in the form of filaments. Each taste corpuscle comprises two classes of cells: supportive and taste cells.
The largest but least numerous papillae in the dorsal surface of the tongue is Vallate papillae.
Vallate papillae:
These are specialized taste buds that present in the posterior dorsum of the tongue.
They are the largest taste buds. They form a 'V'- shape structure.There number can vary between 7- 12.Therefore, the largest but least numerous papillae in the dorsal surface of the tongue is Vallate papillae.

Consider the two samples of sedimentary rock seen here.Predict which rock would be more likely to undergo physical weathering. Explain how and why.
A) Sandstone. Sandstone has more obvious layers of sediments.
B) Shale. Shale is fine grained and is more likely to dissolve in water.
C)Sandstone. Sandstone is made of large sand-like grains and is easily eroded by wind
D)Shale. Shale contains iron which is an element that easily combines with the oxygen in the atmosphere to produce rust.
Answer: A) Sandstone. Sandstone has more obvious layers of sediments.
Step by step explanation: As you take a look at the given pictures, you notice that (Sandstone) Is more closed off than (Shale). So whenever rain comes, rain will seep into the little openings of the rock shale has, causing it to break down.Same for strong wind, since shale isn't as compacted as Sandstorm, then shale will not last very long. Therefore making Sandstone being able to undergo more harsh conditions.
