In silkworms,yellow cocoon (B) is dominat over white cocoon(b). If the mom is BB and the dad is bb, what are the chances they have offspring with yellow cocoons?
Answer:
100 %
Explanation:
Dominance is a genetic phenomenon where a gene variant or allele masks the effects of another allele (of the same gene) in heterozygous individuals. This last gene variant is referred to as the recessive allele. In this case, the silkworm mother can produce only one type of gamete carrying the dominant gene (B) form, while the silkworm father can produce only one type of gamete carrying the recessive gene (b) form. In consequence, from this cross, all offspring (100 %) will be heterozygous (Bb) and therefore they will express the dominant trait (i.e., yellow cocoon).

PLEASE HELP IM TIMED Which of the following statements best summarizes the processes of transcription and translation resulting in the expression of a particular gene?
The genetic information carried by DNA is transcribed into a code that is carried by RNA, which is translated into a specific protein that determines a phenotype.
The genetic information carried by DNA is translated into a code that is copied by RNA and transcribed into a protein chain that results in a specific phenotype.
The genetic information carried by RNA is transcribed into a code that is carried by DNA and translated into a protein chain that results in a specific phenotype.
The genetic information carried by RNA is translated into a code that is copied by DNA and transcribed into a protein chain that results in a specific phenotype.
The genetic information carried by DNA is transcribed into a code that is carried by RNA, which is translated into a specific protein that determines a phenotype. Thus option A is correct.
What are the difference between eukaryotic transcription and translation?The central dogma of life consist of replication, transcription, translation and reverse transcription.
The process in which RNA are formed from DNA is called as Transcription where as the process in which Protein synthesis occur from RNA is called as translation.
Transcription occurs in the nucleus where as Translation occurs in the cytoplasm.
In Initiation phase of transcription RNA dependent polymerase bind to DNA promoters.
The initiation phase of translation involves association of ribosome subunits, tRNA, and initiation factor to mRNA.
Termination step of of transcription includes the release of RNA transcript or mRNA
In translation the ribosome meets stop codons which leads to the dissociation of the ribosome from polypeptide chain. Thus option A is correct.

Cognition is studied indirectly. Please select the best answer from the choices provided T F
The statement "Cognition is studied indirectly" is true.
What is cognition?The mental action or process of obtaining psychological features and apprehension through self-satisfaction, experience, and the senses is the definition of cognition.
Cognitive psychologists are interested in the investigation of mental functions. This relates to the study of cognition, memory, learning, and problem-solving processes in people. Cognitive psychologists are interested in how people think or react psychologically to various situations.
On the other side, behavioral psychologists are interested in researching and observing behavior. It is additional research on the interactions between stimulants and outcomes.
Therefore, the statement is true about cognition.

Polygenic traits are when one phenotype (trait) is controlled by several different genes. The provided example shows human skin color being controlled by 3 different genes. Describe one other trait (don't use skin color!) in any animal that you think could be a Polygenic trait, and explain why you think that it is (HINT: I did mention an example in class yesterday... lets SEE if you remember!).
X-rays carry a small risk of damaging DNA which can lead to cancer. Why are they still used by doctors?
Answer:
Despite the risk of DNA damage and cancer production, X-rays are still used by doctors because the benefit of this diagnostic study outweighs the risk, which in most cases is very low.
Explanation:
Diagnostic radiology studies, such as X-rays and CT scans, are procedures that use ionizing radiation to obtain images of the inside of the body. Prolonged or constant exposure to this type of radiation is harmful because there is a risk of producing damage to DNA and can lead to the development of cancer.
However, the use of X-rays and CT scans are non-invasive diagnostic methods whose information provides an accurate diagnosis of a disease and, when well used, has a very low risk of organ damage.
Ionizing radiation is measured in milisieverts (mSv) and exposure from radiologic studies is in the range of 0.1 to 10 mSv per study. The amount of ionizing radiation a person is expected to receive per year from exposure to their environment is in the order of 3 to 5 mSv per year, so diagnostic imaging studies involve a low risk of organ damage.
Doctors continue to use X-rays as a diagnostic study, despite the risk of cancer and DNA damage, because the benefit —accessible, noninvasive, and cost-effective— far outweighs the risk.

"Image result for why cells can form tumors
Cancer is unchecked cell growth. Mutations in genes can cause cancer by accelerating cell division rates or inhibiting normal controls on the system, such as cell cycle arrest or programmed cell death. As a mass of cancerous cells grows, it can develop into a tumor."
A student is presented with a model of a digestive system and is asked to remove one structure (small or large organ) that will have the largest impact on decreasing chemical digestion. Which structure should the student remove
Answer:
Small intestine
Explanation:
Digestion is the process of breaking down food molecules into simpler and usable forms by the body cells. The process of digestion involved the mechanical aspect and chemical aspect. The mechanical one deals with using physical means like chewing to break down the food particles.
However, the chemical one deals with the usage of chemically-secreted enzymes to work on the food molecules. Lots of digestive organs are involved in this chemical digestion, but, the most of chemical digestion takes place in the SMALL INTESTINE. The small intestine is where most of the chemical digestion occurs including absorption.
Hence, according to this question, the student should remove the SMALL INTESTINE because it will have the largest impact on decreasing chemical digestion.

The Lubber grasshopper is a very large grasshopper, and is black in color with stripes. The color of the stripes exhibit incomplete dominance. Red stripes or yellow stripes may be expressed; however, when alleles are mixed, orange stripes are expressed. What will be the genotypic and phenotypic ratios be for the offspring of two parents that both have orange stripes.
Genotype: ______________________________
Phenotype: _____________________________
Explanation:
Let R be the allele for red stripes.
Let r be the allele for yellow stripes.
Parental phenotypes:
Orange stripes * Orange stripes
Parental genotypes:
Rr * Rr
Gametes:
(R)(r) * (R)(r)
Using a Punnett's Square, we get
F1 generation genotypes:
RR : Rr : rr = 1 : 2 : 1
F1 generation phenotypes:
Red : Orange : Yellow = 1 : 2 : 1.

1. What are the differences and similarities between an asteroids and comets?
or
2.What are the differences and similarities between the moon and a planet?
Answer:
Asteroids or planetoids are small solids in planetary systems. They usually orbit the parent star in their own orbit or as natural satellites (moons) of larger planets.
A comet is a celestial body that is in an elliptical orbit around the Sun. They come from the farthest and coldest areas of the solar system.
Explanation:
The moon is the only natural satellite of the Earth and at the same time the closest celestial body.
It is the brightest celestial body in the night sky, not because it consists of incandescent gases like the sun, but because it reflects sunlight.
A planet is a celestial body that moves directly in an elliptical orbit around a star, not like a natural satellite, which orbits a star while circling around another body.
