The discussion of mutants of arabidopsis with alterations in seed lipid fatty acid composition theoretical and applied genetics is written in below paragraph-
By analyzing the fatty acid composition of samples of seed from 3,000 mutagenized lines, a rich variety of mutant Arabidopsis with different seed lipid compositions was discovered. Defects in the elongation of 18-1 to 20-1, desaturation of 18-1 to 18-2, and desaturation of 18-2 to 18-3 were caused by a series of mutations that were found. The wild type showed partial dominance over the mutant allele in each of these instances. These findings, in addition to findings from other studies, indicate a significant role for gene dosage in influencing the fatty acid content of seed lipids. A mutation that increased the accumulation of 183 was also discovered.
A broad variety of mutant Arabidopsis with various seed lipid compositions was found by examining the fatty acid composition of seed samples from 3,000 mutagenized lines. A number of mutations were discovered that were responsible for defects in the desaturation of 18-1 to 18-2, 18-1 to 18-2, and 18-2 to 18-3. In each of these cases, the mutant allele was somewhat dominant over the natural type. These results, together with those from previous studies, point to a significant role for gene dosage in affecting the fatty acid composition of seed lipids. Additionally, a mutation that increased the accumulation of 183 was found.
What are mutants?A mutant in biology, and particularly genetics, is an organism or new genetic characteristic that arises from or is brought about by a mutation, which is typically an alteration of the DNA sequence of an organism's genome or chromosome.

Glycolysis results in the net production of which of the following sets of molecules per glucose molecule?
Answer:
Glycolosis has a net gain of 2 atp
Explanation:
It produces 4 but you invest 2 to start so its only net gain of 2
You also ge 2 pyruvate and 2 NADH
Two pyruvate molecules, two ATP molecules, and two NADH molecules are the substances produced in the process of glycolysis.
These substances are gained from glucose in order to generate energy which is needed in different activities of the cell. ATP is the molecule which is used by the cell for doing activities which needs energy.
Both pyruvate and NADH molecules are also converted into ATP molecules in the end and used by the cell so we can conclude that in the process of glycolysis, two pyruvate, two ATP, and two NADH molecules are formed.

a population of deer was threatened with overpopulation until cheetahs were imported. after a couple of years, there were fewer deer, but the average running speed of the deer had increased. this is an example of Predator-prey coevolution.
Overpopulation is a condition when a species have so much population that the carrying capacities of the nature starts getting exhausted.
Overpopulation is also not good for a population because it will causes depletion of the resources which will ultimately lead to the extinction of the species.
When the cheetahs are introduced in an area overpopulated with deer species, they will keep the population in check. Also, as deer have to save itself they have to increase their running speed to survive and hence evolve with same adaptation.

What happens during the first two stages of cellular respiration?
Answer:
Cellular respiration uses energy in glucose to make ATP. Aerobic (“oxygen-using”) respiration occurs in three stages: glycolysis, the Krebs cycle, and electron transport. In glycolysis, glucose is split into two molecules of pyruvate. ... Life first evolved in the absence of oxygen, and glycolysis does not require oxygen.

Predict: Of the molecules shown on the molecules pane, which do you think are inputs (ingredients) in photosynthesis? Which do you think are outputs
Answer:
Input ingredients = water, carbon dioxide, energy from the sun
Output ingredients = glucose, oxygen
Explanation:
Photosynthesis involves the production of carbohydrates from inorganic products. The chemical equation for the process is represented below:
[tex]6CO_2 + 6H_2O + sunlight--> C_6H_1_2O_6 + 6O_2[/tex]
Water and carbon dioxide molecules combine in the presence of sunlight radiation to give glucose and oxygen molecules.
Input ingredients = water, carbon dioxide, sunlight
Output ingredients = glucose, oxygen
The molecules are shown on the molecules pane inputs (ingredients) in photosynthesis -
Inputs - H2O + CO2output - C6H1206 + O2Photosynthesis is a cellular metabolic process, regulated by enzymes to convert radiant energy to chemical energy, its inputs and outputs are the following:
Inputs: carbon dioxide and water from which organic compounds are synthesized, using the light absorbed by pigments as an energy source.Outputs: sugar and oxygen are produced in photosynthesis as a food source that is energy for the plant.Thus,

How does the size of the fetal face relate to the cranium? how does this compare to the adult skull?.
The face is foreshortened and it is overshadowed by the large cranium. While the mandible and maxillae are very tiny.
Cranium is the outer layer that protects the skull. It consists of three parts: the frontal bone, occipital bone, and two parietal bones.
The frontal bone is a single bone that transforms into a forehead and it is positioned atop the eyes' orbit.
The frontal bone also forms both sides of the upper jawbone or maxilla. While the two parietal bones form the top and side of the human skull.
They also take part in forming the largest part of the upper jawbone like the frontal bone.

What are the possible blood types of a baby with a mom who is heterozygous for blood type A and a dad with type O?
Answer:
A & O group
Explanation:
Dad will be having io io allele and mom will be having ia io
The possible blood types for the baby are either A or O, with equal likelihood of 50% for each.
What is blood type?A classification system called blood type explains whether or not specific antigens are present on the surface of red blood cells. Each of the four major blood types—A, B, AB, and O—has distinct antigen markers.
A and O are the two possible blood types for a child whose mother is heterozygous for blood type A (genotype AO) and whose father has type O (genotype OO).
A baby has a 50% chance of acquiring the A allele from the mother and a 50% chance of inheriting the O allele from the father because each parent gives one of their two blood type genes to their offspring.
Baby with blood type A inherits the A allele from the mother and the O allele from the father (genotype AO).
The child will have blood type O if both parents carry the O allele (genotype OO).
Therefore, the possible blood types for the baby are either A or O, with equal likelihood of 50% for each.

humans have hundreds of different g-protein-coupled receptors. while these receptors all have distinct amino acid sequences, they all have in common: guanine nucleotide exchange activity
What is guanine nucleotide?
Guanine nucleotide exchange factors (GEFs) are proteins or protein domains that stimulate the release of guanosine diphosphate (GDP) to enable the binding of guanosine triphosphate, hence activating monomeric GTPases (GTP). It has been demonstrated that guanine nucleotide exchange activity occurs in a number of unrelated structural domains. While some GEFs are exclusive to a particular GTPase, others can activate numerous GTPases.
Small GTPases are activated by proteins or protein domains known as guanine nucleotide exchange factors (GEFs). In intracellular signaling pathways, small GTPases function as molecular switches and have a wide range of downstream destinations. The Ras superfamily of GTPases, which is made up of the most well-known GTPases, is crucial for key cellular functions such cell division and proliferation, cytoskeletal structure, vesicle trafficking, and nuclear transport. GTPases can have their activity controlled by GEFs and the opposing GTPase activating proteins because they are active when bound to GTP and inactive when attached to GDP (GAPs)

Who eats whom in an ecological community is described by food webs. Food webs, which are composed of interconnected food chains, help us comprehend how changes to ecosystems—such as eliminating a top predator or introducing nutrients—affect numerous species both directly and indirectly.
The foundation of aquatic food webs is made up of phytoplankton and algae. Primary consumers like zooplankton, small fish, and crustaceans consume them. In turn, fish, small sharks, corals, and baleen whales consume the primary consumers. Large sharks, billfish, dolphins, toothed whales, and large seals are some of the top ocean predators. All aquatic life in this food chain is consumed by humans.
