Tay-sachs disease is caused by a mutation in the hexa gene located on chromosome 15. tay-sachs follows an autosomal recessive pattern of inheritance. with the help of the diagram, identify which of the offspring will be an unaffected carrier. a diagram showing the genes of parents who are carriers of tay-sachs disease a. a, b, and c b. b and c c. a and d d. a e. d
Tay-Sachs disease follows an autosomal recessive pattern of inheritance, so the unaffected carrier will be the child a.
The correct option is d, a.
What is Tay-Sachs disease?Tay-Sachs is a neurodegenerative disorder, which causes the deficiency of an enzyme called hexosaminidase A.
The enzyme hexosaminidase A present in the lysosome helps in the digestion of fats.
This disorder causes the excess accumulation of lipid or fat in the ganglion cells.
This causes dysfunction of the central nervous system.
The correct option is d, e.

Will the entire starch molecule be able to enter the cells of the digestive tract?
Particularly important dietary carbohydrates include starch and disaccharides such as lactose and sucrose. None of these molecules can be absorbed for the simple reason that they cannot cross cell membranes unaided and, unlike the situation for monosaccharides, there are no transporters to carry them across.

Answer:
Mark me brainliest please I really need itExplanation:
In biology, evolution is the change in the characteristics of a species over several generations and relies on the process of natural selection. The theory of evolution is based on the idea that all species are related and gradually chamge over time.Darwin's theory consisted of two main points; 1) diverse groups of animals evolve from one or a few common ancestors; 2) the mechanism by which this evolution takes place is natural selection.Evidence that supports the theory of evolution are fossils, embryological studies, anatomical and morphological characteristics (homologous organs, analogous organs, vestigial organs), molecular biology (comparing DNA sequences).Can someone please help me? :(
Answer:
B i think or C
Explanation:
Because in the way I am thinking it's B, "School cooks should be educated on allergies to peanuts." It makes the most sense
Answer: b
Explanation:
it can't be a since source 2 says "few people recognize..." which contradicts "students know what to do..."
it can't be c because there is no source comparing peanut allergies now vs. past.
it can't be d because you cannot infer this from the given data.
leaving us with b because since a majority of peanut allergies happen at school and not many know how to deal with an event with a peanut allergy, then teaching cooks about peanut allergies will help students in the case of an allergic reaction in school.
hope this helped! ♡

D) According to the graph, obesity and diabetes are intertwined, which could be why obesity and diabetes are linked.
E) Diabetes had the greatest rise in prevalence in 1997 until 2000, with prevalence percentages between about 76% to 78%.
Explanation: Explanation for these answers are below:
D) Looking at the graph, obesity and diabetes had similar prevalences in 1997 and 1998, and started to part ways a little in 1999. In fact, even without the graph, scientists have known for a long time that people who have obesity also have diabetes. This graph supports that claim because of how closely linked diabetes and obesity are and how similar the prevalence percentages are.
E) Diabetes had the greatest rise in 1997 to 2000, which had a 78% prevalence by 2000. Obesity had very similar prevalence percentages from 75.5% to 77% in 1997 to 2000.

What prior species of hominids did homo sapiens encounter in europe approximately 40,000 years ago?.
Answer:
Neanderthals
Explanation:
Homo sapiens encountered neanderthals in europe and had offspring.
The prior species of hominids that Homo sapiens encounter in Europe approximately 40,000 years ago is Neanderthal.
What is species?
Species is the term that is used to classify different organisms. Species is the second last classification, which means most similar organisms are present in this classification. The traits are mostly similar in these organisms.
While the form of the head and face was not significantly different from that of current humans, there were still quite a few distinctions. Most notably that of the modern human head, which is shorter and has a less prominent facial front. Neanderthal was a former human.
Therefore, the Neanderthals are the ancestors of Homo sapiens, who first encountered them in Europe some 40,000 years ago.

Why is cellulose important for explaining how carbon atoms get "locked up" (stored) in a tree as long as it is alive?
O Cellulose is what is produced in photosynthesis.
O Cellulose is used to make new cell walls, when tree cells divide, which become part of the tree.
O Cellulose is made up of CO2 molecules from the atmosphere that stay in the tree.
O Cellulose is what the trees use to make starch, which stores energy for the tree to use later.
Cellulose is a very common organic chemical compound in the plant kingdom and is made up of CO2 molecules from the atmosphere that stay in the tree.
What is cellulose?It is a biopolymer, that is, a long chain of carbohydrates, composed exclusively of glucose molecules (β-glucose) linked together by hydrogen bonds.
It is synthesized by the photosynthesis of plants and whose main function in plant tissues is support, that is, it is part of the cell wall of plant cells.
Therefore, we can conclude that cellulose is a very common organic chemical compound in the plant kingdom and is made up of CO2 molecules from the atmosphere that stay in the tree.

A student is investigating the strength of electromagnets she created using batteries, wire, and nails.
She uses two different-sized nails and varies the number of coils of wire around the nail to determine how many paper clips each configuration can lift. She makes a data table of the results.
The student hypothesizes that the number of coils has a cause-and-effect relationship on the strength of the magnetic devices she made. Which would be the best way for the student to test the devices to be sure that her hypothesis is accurate?
Explanation:
You will change two variables to make different electromagnets: the number of wire coils around the nail (10 or 20) and the number of D cell batteries.
What kind of compounds are formed by carbon
Answer:
Carbides: Carbides are binary compounds formed by carbon and another element with a lower electronegativity. Examples include Al 4 C 3, CaC 2, SiC, TiC, WC.
Carbon Halides: Carbon halides consist of carbon bonded to a halogen. Examples include carbon tetrachloride (CCl 4) and carbon tetraiodide (CI 4 ).
Carboranes: Carboranes are molecular clusters that contain both carbon and boron atoms. An example is H 2 C 2 B 10 H 10.
