Hereditary fructose intolerance is a genetic condition caused by a variant in the ALDOB gene, which is critical for fructose metabolism. Infants with this condition do not initially display symptoms, but as they are transitioned from breast milk or formula to solid foods, in particular fruit-based foods, they begin to display symptoms, which include vomiting, diarrhea, and low blood sugar. Individuals who do not consume fructose do not display these symptoms. Which of the following describes this condition?
a. It is incompletely penetrant, due to environmental factors.
b. It has variable expressivity, due to environmental factors.incorrect
c. It is incompletely penetrant, due to genetic factors.
d. It has variable expressivity, due to genetic factors.
It has variable expressivity due to the environmental factors.
The variation in expressivity occurs due to the environmental factors of that individual. Expressivity describes the differences observed in the phenotype between two individuals that belongs to same genotype.
In the condition, when the patient is allowed to consume the fructose based food, so it expresses the change in its body due to no tolerance against fructose so we can conclude that the change occurs due to environment not due to genetics.

A. lipids
B. amino acids
C. DNA
D. monosaccharides
Fatty acids are building blocks of lipids. The correct option is A.
Fats and oil are known as lipids.
Lipids are part of the classes of food which are made up of high proportion of carbon and hydrogen with very little oxygen.
Fats are solids and oils are liquids at room temperature. They serve the following functions to the body:
They provide the body with energyThey are solvents for fat-soluble vitamins and hormones.Before lipids can be absorbed into the body, they must be broken down into fatty acids and glycerol.

Answer:
The answer is below
Explanation:
Definition:
Taxonomy - The science of addressing, describing and classifying organisms (plants, animals and microorganisms of the world).
Why, in your opinion, are there no final answers in science? Relate your answers to the study of the learning process.
Answer:
In science, answers do not have a final answer because not everything about the answer can be answered. Nothing can be told as 100% correct, and parts of the answer can change over time. For example, if you are doing a science project on how much water a plant needs to grow, each plant will grow differently, and you would have to wait and see how much water it needs to grow.

White Leaf Disease is a devastating disease that
affects sugar cane crops in Thailand and has become a
major issue for farmers. The disease starts with a white
line forming in the center of the sugar cane's leaves,
which can change in size and shape as it develops.The sugar cane's new leaves will become increasingly whiter, often having stunted growth, and resulting in the sugar cane being less productive than the non-
infected plants, Scientists are trying to determine
what organelle must be damaged to produce the
observed results,
White leaf disease is caused by phytoplasma. The disease infects the leaves and create white spots in them.
The farmers in Thailand are facing this issue with sugarcane crops. The organisms infect phloem tissues in sugar cane and cause the leaves to turn white.
The size and shape can change as sometimes there are fine white lines created while sometime there are white spots.
Scientists are trying to deal with such disease and an spray of liquid copper has been found beneficial to treat this disease. The white spot fungus stops to spread with the spray.

The CT reveals several issues with the cranial structure, one of which might be in the cribriform plate but the image isn't well defined. What non-invasive test can you do to test if the cribriform plate is severely damaged? Why?
The non-invasive test that can be used to test if the cribriform plate is severely damaged is called the pledget study.
CRIBRIFORM PLATE is the part of the ethmoid bone that forms the nasal cavity.
The olfactory nerve which is part of the cranial nerves passes through the small opening found in the cribriform plate.
A damage to the cribriform plate leads to cerebrospinal fluid (CSF) leak which usually comes out from the nose and ears.
Therefore to test if the cribriform plate is severely damaged, the pledget study is performed.
Pledget study is a non-invasive method of diagnosing a CSF leak.
To perform this test,
Cotton pads called Pledgets are placed in the nostrils.If the leaking fluid contains CSF it will be detected.The presence of CSF shows that there is damage to the cribriform plate.
This method is non invasive because it doesn't require the breaking or opening of any part of the body.

Given the gene sequence GGACCGTCGATCTTC, which of the following choices would represent an inversion mutation?
A. CCACCGTCGATCTTC
B. GGACTCGATCTTC
C. GGACCGTCGATCTTC
D. GGACCGTCGATCCTT
Reset Selection
ASAP
Answer:
D. GGACCGTCGATCCTT
Explanation:
Mutation refers to any change in the nucleotide sequence of a gene. Mutation can be of different types depending on how it occurs. According to the question, an INVERSION mutation is a type of mutation in which a segment of a gene gets broken off and reattached in another way on the same DNA. Hence, the only change in inversion mutation is the arrangement of the nucleotide bases on the gene.
Considering the nucleotide sequence: GGACCGTCGATCTTC, the sequence that describes an occurrence of inversion mutation is: GGACCGTCGATCCTT because the segment TTC in the original sequence has been rearranged as CTT in the mutated sequence.

Part iv. What adaptations are associated with a folivory diet? Give an example of a primate that has this diet.
Part v. What adaptations are associated with vertical clinging and leaping? Give an example of a primate that practices this form of locomotion.
The examples that you need are 1-Gummivory: marmoset, tamarins; 2-Frugivores: spider monkey, ray-bellied night monkey (owl monkey); 3-Folivory: howler monkey, leaf monkey, colobine; and 4-Vertical clinging and leaping: lemurs and tarsiers
A gummivore is an animal (in this case, a primate) with a feeding strategy that depends on the sap or gum from trees. It is a type of diet that consists primarily of exudates. Some adaptations observed in these species include: 1-specialized anterior teeth in order to stab bark; 2-well-developed claws for clinging to trees
Frugivores primates have a feeding strategy mainly based on raw fruits. Some adaptations observed in these species include 1-low rounded molar cusps and 2-broad incisors.
Folivore primates (also called leaf-eating monkeys) have a feeding strategy mainly based on leaves. Some adaptations observed in these species include 1-narrow incisors, 2-broad molars (high shearing crests), 3-thin enamel molars.
Vertical clinging and leaping is an arboreal locomotor pattern practiced by lemurs and tarsiers. These animals push off from one vertical support with their hindlimbs to land on another vertical support. Some adaptations observed in these species include 1-hips, knees, feet, arms, and tails that facilitate climbing and leaping, 2-large hip extensor muscles and 3-specialized minor muscles.
