8. In snapdragons, red flower (R) color is incompletely dominant over white flower (1) color. The heterozygous (Rr)
plants have pink flowers.
A. If a red-flowered plant is crossed with a white-flowered plant, what are the genotypes and phenotypes
of the plants F1 generation?
B. What genotypes and phenotypes will be produced in the F2 generation?
C. What kinds of offspring can be produced if a red-flowered plant is crossed with a pink-flowered plant?
D. What kind of offspring is/are produced if a pink-flowered plant is crossed with a white-flowered plant?
Answers
Answer:
A. Genotypes: Rr
Phenotypes: All Pink
B. Genotypes in the F2 generation: RR, 2Rr, rr
Phenotypes: red, pink and white
C. 1RR (red): 1Rr (pink).
D. 1Rr (red) : 1rr (white).
Explanation:
This question involves one gene coding for flower color in snapdragon plants. The allele for red color (R) is incompletely dominant over the allele for white color (W), to form an intermediate pink color (RW).
A. If a red-flowered plant (RR) is crossed with a white-flowered plant (rr), the genotypes of the offsprings will be Rr with a pink color phenotype.
B. In the F2 generation i.e. Rr × Rr, the following will be produced: RR (red), 2Rr (pink), and rr (white).
C. if a red-flowered plant is crossed with a pink-flowered plant, the following will be produced: 1RR (red): 1Rr (pink).
D. if a pink-flowered plant is crossed with a white-flowered plant, the following will be produced: 1Rr (red) : 1rr (white).

if a gene is made up of 20% adenine, how much thymine, guanine, and cytosine will there be
Answers
Explanation:
You have 20% of adenine. If you have 20% of adenine than you have 20% of thymine, because the amount of adenine and thymine is equal. 20% plus 20% is 40% of adennine and thymine. From 100% DNA bases subtract 40% and you will get 60%. Then divide this by 2 and you will get 30%. 30% of guanine and 30% of cytosine, because their amounts are equal in the DNA stand.
The graph below shows the breakdown of a protein in the human stomach without a digestive enzyme.
Answers
Answer:
B
Explanation:
Take the test
The breakdown of protein in the presence of enzyme has lower activation energy.
The breakdown of protein in the stomach is achieved with the loss of peptide bonds, and the complex is broken down into amino acids.
What is breakdown of protein?The protein is broken down in the digestion at small intestine and stomach. The graph represents the energy of the reaction with the progress of protein degradation.
The energy of the reaction is highest when the protein breakdown activation is processed. The enzyme is the catalyst, that acts in fasting the reaction with the lowering of activation energy.
Thus, the breakdown of protein in the presence of enzyme has lower activation energy.

In individual is asked to smile broadly. It is observed that the left corner of the mouth cannot be elevated in a normal fashion. The individual is then asked to wrinkle the brow. The brow is observed to wrinkle in a normal fashion. Which cranial is involved in this facial control issue, and is the lesion in that nerve or within the central nervous system?
Answers
Answer:
Cranial nerve 7 and YES the lesion is within the Central Nervous System.
Explanation:
The Central Nervous System ( CNS) consists of the brain and the spinal cord. There are 12 pairs of cranial nerves originating from the nuclei in the inferior surface of the brain, some sensory, some motor and some mixed.
Cranial nerve 7 is also known as the Facial nerves. These nerves are composed of both motor and sensory nerve fibre, arising from nuclei in the lower part of the pons. The motor fibres supply the muscles of facial expression. When lesion occurs at the base of the pon which is part of the CNS, it can affect the facial expressions such as observed, that the left corner of the mouth cannot be elevated in a normal fashion.
Therefore, Cranial nerve 7 ( Facial nerve) is involved in this facial control issue and YES the lesion is within the Central Nervous System.

Well, here we have beta decay.
Beta-decay is when a beta particle (an electron or a positron) is emitted from an atomic nucleus (usually a neutron-rich nucleus). We know that beta decay is a consequence of the weak force or weak interaction (the force responsible for the radioactive decay of atoms)

a. The mRNA leaves the nucleus and goes to a ribosome open choices for ranking.
b. The building blocks of proteins, are carried to the ribosome by tRNAsAmino acids.
The process of deoxyribonucleic acod starts with replication to transcription and translation.
Replication involves the formation of a complementary base from a old or template DNA Strand this then serve as a template for transcription.
transcription involves the coping of information on the DNA to an intermediate mRNA ( messanger ribonucleic acid) in the nucleus which then move from the nucleus to ribosome in the cytoplasm where translation occurs.
Translation is the conversion of the information on the mRNA to an amino acid with the help of enzyme transferse ribonucleic acid(tRNA).

The type of weathering seen in the pictures is mechanical weathering.
Weathering is the process by which rocks, minerals, and other geological materials are broken down and altered over time by various physical, chemical, and biological processes. It is a fundamental part of the Earth's surface dynamics and plays a significant role in shaping landscapes.
Mechanical weathering involves the physical breakdown of rocks into smaller fragments without changing their chemical composition. It increases the surface area of rocks, making them more susceptible to further weathering.

Explain why the structure of a brain cell would differ from that a red blood cell.
Answers
Answer: Red blood cells carry a specific type of protein, called hemoglobin, which is able to bind oxygen and release it in other tissues. A nerve cell doesn't have this protein because it doesn't need to bind oxygen. Instead, the nerve cell uses other proteins that help it transmit signals to other cells.
Explanation:
Brain is composed of brain cells known as nerve cells where as RBC also known as red blood corpuscle is a component of blood.
What is the structure of a brain cell ?The brain's neurons are the cells that transmit and receive chemical and electrical messages. They serve as the brain's building blocks and act as information carriers for all of the body's neurons, muscles, and tissues. You can think, feel, move, and take in information with their help.
Erythrocytes, sometimes known as red blood cells, are one of the elements of blood. Our bone marrow continuously produces them. One billion red blood cells can be found in just two or three droplets of blood, which is what gives human blood its recognizable red color. From our lungs, red blood cells transport oxygen to the rest of our bodies. The carbon dioxide is then transported back to our lungs, where it is expelled.
Therefore, the structure of a brain cell differs greatly from red bood cell.

Describe the basic histological (tissue) structure of the mucosa layer in the alimentary canal. Identify the unique features of the mucosa in the stomach and the duodenum, and explain how this uniqueness determines the function of the stomach and the duodenum.
Answers
Answer: The basic tissue structure of the mucosa layer of the alimentary canal consists of:
--> mucous membrane
--> lamina propria
--> muscularis mucosa
Explanation:
The MUCOUS MEMBRANE forms the innermost layer of the alimentary canals which includes the stomach and the duodenum (small intestine) . It's major functions is protection, secretions and absorption. The type of mucous membrane found in the stomach and duodenum is the Columnar epithelial cells. Not numerous gastric glands are situated below the surface in the mucous membrane of the stomach. They consist of specialised cells that secrete gastric juice that aids in the digestion of food. While the duodenal mucosa consists of mucous producing goblet cells. These cells produce a viscous, alkaline mucus that protects against the acidic gastric juices and pepsin. The folding of these mucosal cells (microvilli) provides a large surface area to optimize nutrient absorption.
The LAMINA PROPRIA: This layer separates the mucous membrane and the muscularis mucosa. It is made up of connective tissues which supports the blood vessels that nourishes the inner epithelial layer. In both the stomach and duodenum, digested nutrients are absorbed into the capillaries.
MUSCULARIS MUCOSA: This is made up of thin layer of smooth involuntary muscles. The contraction and relaxation of these muscle layers occurs in waves, which push the contents of the tract onwards. This type of contraction is called peristalsis which occurs in the duodenum. While in the stomach, these muscles allows for the churning motion characteristic of gastric activities.
