5. A cross is made between a pea plant that has constricted pods (a recessive trait; smooth is dominant) and is heterozygous for seed color (yellow is dominant to green) and a plant that is heterozygous for both pod texture and seed color. Construct a Punnett square that depicts this cross. What are the predicted outcomes of genotypes and phenotypes of the offspring
Answer:
Genotypes:

During nitrogen fixation, nitrogen gas in the atmosphere is converted into a form that ____ can use. a plants b animals c humans d all of the above
Answer:
A. Plants
Explanation:
Nitrogen fixation is one of the processes involved in the NITROGEN CYCLE. It is the process whereby atmospheric nitrogen (N2) is converted into nitrogenous compounds such as ammonia, nitrates by certain nitrogen-fixing bacteria such as AZOTOBACTER.
The nitrogenous compounds which nitrogen fixation converts N2 into are in a form that PLANTS can use. Plants cannot utilize nitrogen gas, hence, the importance of this conversion into a form that plant can make use of.

An individual that is heterozygous for flower color and for height (PpTt) is test crossed. What is the phenotypic ratio of the offspring
Answer:
9:3:3:1
Explanation:
This type of crossing that involves two characters is referred to as dihybrid crossing. Generally, when there is a dihybrid crossing for heterozygous genes for both parents, the phenotypic ratio is usually 9:3:3:1 as shown in the figure in the attached document below.
Assuming the colour is White (P) and Black (p) and the
Height is Tall (T) and short (t)
The possible phenotypes will be in the ration
9 - White and Tall
3 - White and short
3 - Black and Tall
1 - Black and short
It should be noted that phenotypic ratio (phenotype) describes the outward appearance (what can be see physically) and not the genetic make-up. Thus, where there is a dominant character like P or T, the recessive characters are not considered to have been expressed.

HELP! If a person has sickle cell anemia, about 50% of their red blood cells will be sickle shaped. But, this is due to a mutation in the hemoglobin gene which affects the shape of some of the cells. What percentage (%) of the cells in their body will have the abnormal and nonfunctional hemoglobin gene? Why did you choose that number?
Answer:
it may be the answer
With less oxygen, the abnormal hemoglobin S gene can cause rigid, nonliquid protein strands to form within the red blood cell. These rigid strands can change the shape of the cell, causing the sickled red blood cell that gives the disease its name.
How can scientists use anatomical structures and embryology as evidence of how organisms evolved?
Directions: In rabbits, gray hair (G) is dominant to white hair (g), and black eyes (B) are dominant to red eyes (b). These two traits are independent of each other. In other words, a female rabbit with the genotype GgBb may produce eggs with the alleles GB, Gb, gB, or gb. To predict the probability of these sorts of crosses, we will make a dihybrid Punnett Square.
What are the phenotypes (descriptions) of rabbits that have the following genotypes:

How many G3P would be produced if there are 36 Carbon Dioxide that enters the Calvin Cycle?
a. 8
b. 10
c. 12
d. 14
Answer:
c
Explanation:
Im pretty sure, so sorry if I'm wrong though.
c. 12
Calvin cycle:
In Calvin cycle number of carbon atoms are constant in CO₂ and used to construct three-carbon sugars. This manner is fueled by, and established on, ATP and NADPH from the mild reactions.The Calvin cycle reactions occurs in three main stages: carbon fixation, reduction, and regeneration of the starting molecule.So, in the question it is asked how many G3P would be produced if there are 36 carbon dioxide that enters the Calvin cycle. Thus the answer is 12
In order for one G3P to go out the cycle (and move in the direction of glucose synthesis), 3 CO₂ molecules need to input the cycle, imparting 3 new atoms of constant carbon.

Arthritis and other similar diseases can cause a narrowing of the spinal foramen. The images below show a healthy spine and a spine with a narrow foramen.
Which symptom would an individual with a narrow foramen most likely experience?
A.
increased flexibility from the constriction of muscle
B.
poor posture from loss of tendon attachment sites
C.
back pain from the compressed nerves
D.
lower blood pressure from increased blood flow
Answer:
The symptom most likely to be experienced by an individual with a narrow spinal foramen is back pain from the compressed nerves, according to the image.
Explanation:
One of the consequences of inflammatory processes affecting the vertebrae is the loss of the normal configuration of these bone structures.
The narrowing of the vertebral foramen as a result of arthritis, among other causes, can compromise the emergence of peripheral nerve roots, producing pain as a symptom. Long-term root compression can also cause compromised peripheral nerve function, such as paresthesias, numbness and paralysis.
An individual with a narrow spinal foramen will have back pain, due the compressed nerves, as a result of this condition.
The other options are not correct because they are not direct consequences of the narrowing of the spinal foramen.
Answer: Back pain from the compressed nerves.

For which object would a geologist use carbon-14 dating to determine age?
O Animal bones
O Fossilized plants
O Sedimentary rocks
O Volcanic rock
Answer:
O Animal bones
Explanation:
In the upper atmosphere, Radioactive Carbon-14 is usually produced. In plants, it is incorporated by photosynthesis into organic molecules, later ingested by hetrotrophs.
It is used for the radiocarbon dating process of fossils and formations. Because of the unstable nature of the isotope used and the consistent rate of decay, radioactive isotope dating is an important way of detection in organic material. Here, this is a the measure of the time taken for half of the radioactive material to break down- this is called the half life for Carbon this is 5,730 years.
In animals, the Carbon-14 ingested is eventually incoporated into their bones. After they die, bones become dessicated, and the Carbon 14 is slowly broken down to become Nitrogen.

The naming system mentioned in the given question is binomial nomenclature.
What is binomial nomenclature?It is the biological system of naming the organisms in which the name comprises two terms. In this, the first term demonstrates the genus, and the second term demonstrates the species of the organism.
Therefore, in the given question, Canis refers to the genus, while lupus, latrans, and familiaris signifies the species.

Explanation:
The DNA or deoxyribonucleic acid also referred to as Double-Helix is found in the nucleus of the cell. It holds the genetic code passed from parents to offsprings during reproduction. DNA strands and proteins form a complex in the nucleus. The DNA polymerase as well as ligase and helicase help in the replication and repair of DNA strands.
The RNA is complementary to its DNA counterpart. It is synthesized from the DNA by the RNA polymerase during the process of transcription. A sequence of three DNA or RNA is called a condon, and each condon is an Amino acid or stop bit. The RNA has a single-helix shape
Central Dogma is crucial for the transfer of genetic information as well as for the proper functioning of the organisms. Central Dogma mainly comprises Replication, Transcription and Translation.
Replication is a process in which the DNA makes a copy of itself with the help of enzymes DNA polymerase, ligase, helicase and many more.The replicated DNA undergoes transcription in which DNA gets transcribed into mRNA with the help of RNA polymerases and many other factors. The transcribed mRNA then forms amino acids and the amino acids produce codons and protein which is essential for cell structure and functioning.
