Tay-Sachs disease is a genetic disorder that results in the destruction of neurons due to a buildup of sphingolipids in the cells. Which organelle is malfunctioning in Tay-Sachs
Answer:
Lysosomes
Explanation:
Tay-sachs disease is a rare Autosomal recessive disease that causes neurodegenerative disorder.
Deficiency of an enzyme Hexosaminidase A results in excessive accumulation of gangliosides (sialic acid containing glycosphingolipids) in the brain and nerve cells.
It is a lysosomal storage disease .Absence of the enzyme Hexosaminidase A ,that breakdowns substance like fats results in accumulation of such substance in the lysosomes.Too much accumulation of fats in the lysosomes destroy the cell.

Cellular respiration is called an aerobic process because it requires _______________.
Answer:
Cellular respiration is called an aerobic process because it requires oxygen and carbon dioxide.
Explanation:
Cellular respiration is the process through which cells convert sugars into energy. The energy comes from the fuel molecules such as Glucose(sugar) or Lipids(fats). In cellular respiration, Glucose molecule is dismantled in the presence of oxygen. The bonds between the glucose break forming a simpler molecule and energy is released in small amounts. Some of the energy is stored by cell in the form of ATP while rest is lost as heat. So, ATP is formed from glucose through endergonic and exergonic reactions. The aerobic breakdown of glucose molecule accompanying synthesis of ATP is called celluar respiration. Carbon dioxide and water are produced as by-products.

Most of the organisms are aerobes. They breakdown sugar involving participation of molecule of oxygen and release the energy in the form of ATP and release carbon dioxide and water as by-product.
[tex]\texttt{(ii)}[/tex]Anaerobic Reaction: An = Without, aero = Air, bic = Life and Respiration.
Some organisms obtain energy by braking down sugar in absence of oxygen. This type of respiration is called anaerobic respiration and organism are called anaerobes. Many micro-organism including yeast can repire anaerobically.
There are 2 types of anaerobes,
Obligate Anaerobes - Which never need oxygenFacultative Anaerobes - Which can respire with/without oxygen_____________________________________Best Regards,'Borz'

Which statement explains the difference in chromosomes in fruit fly (2n=4)?
O Diploid cells have 2 chromosomes and haploid cells have 4 chromosomes.
O Fruit fly gametes have 2 chromosomes while parent cells have 4 chromosomes.
O Male gametes have 2 chromosomes and female gametes have 4 chromosomes.
O Some fruit fly parent cells have 2 chromosomes and others have 4 chromosomes.
Answer:
O Fruit fly gametes have 2 chromosomes while parent cells have 4 chromosomes.
Explanation:
The fruit fly is a diploid (2n) species with a chromosome number equal to 4, which means that somatic cells have two sets of homologous chromosomes, each set composed of two chromosomes (2n = 4). Moreover, fly gametes are haploid (n) cells, containing each a complete set of two non-homologous chromosomes (i.e., half the amount of DNA compared to parent cells). During meiosis, a single cell divides twice following one complete round of DNA replication, producing thus four gametes with a haploid number of chromosomes.

A scientist would expect a newly found arganism to be made of cells because of _______
A.The cell theory
B.Osmosis
C.Adaptation
Answer:
A. The cell theory
Explanation:
A scientist expects every newly formed organism to be made up of cells because of the knowledge of cells.
From the cell theory, we know that the cell is the fundamental and basic unit of life.
Also, all cells are derived from pre-existing cells.
From these properties of cells, it is pertinent that in all life forms, we are able to find cells within them. Also, organisms are made up of cell combinations to give multicellular structures Although, some organisms exists at the cellular levels.Genetically modified (GM) crops are foods that have had their genomes modified, allowing humans to increase the production of certain crops. Farmer A purchases GM seeds that are immune to a specific herbicide. She plants these seeds in rows over seventeen acres. The following spring, Farmer A's neighbor, Farmer B, tells her that nearly a third of the plants in his crop fields have the same immunity.
Which of the following describes the most likely explanation for this occurrence?
a.Rabbits which frequent both fields carried the seeds across to Farmer B's land.
b.Farmer A's crops cross-pollinated with Farmer B's crops on the neighboring land.
c.The two farms share an irrigation system which transmitted the immunity from one field to another.
d.By increasing the genetic diversity in Farmer A's crops, they have out-competed the crops on Farmer B's land.
Answer:
B.Farmer A's crops cross-pollinated with Farmer B's crops on the neighboring land.
Explanation:
Herbicide resistant genes may transferred to from Farmer A's plants to farmer B's plants via pollination. Option B is correct.
Jumping Gene:
It is a concept in biology which says that the genes present in the one plant can transfer to another plant via pollination. They are also known as Transportable elements.
Here Herbicide resistant genes transferred to from Farmer A's plants to farmer B's plants.
Therefore, Herbicide resistant genes may transferred to from Farmer A's plants to farmer B's plants via pollination.

Which of the following is true about the principle of the conversation of mass
Answer:
I don't see a file attached.
In physics and chemistry, the law of conservation of mass or principle of mass conservation states that for any system closed to all transfers of matter and energy, the mass of the system must remain constant over time, as the system's mass cannot change, so quantity can neither be added nor be removed.

What is the difference between dominant and recessive traits?
Answer:
Dominant trait is the trait that the offspring are more likely to have, like if a dominant trait is to have green eyes and the recessive trate is blue eyes, then the offspring are more likely to have green eyes, but its likely to have blue eyes too.
Dominant traits show up more than the recessive trait, because its stronger than the recessive trait.
Explanation:
Answer:
Dominant traits are traits that are always expressed when the connected allele is dominant. This is for even if only one of the copy of the dominant traits exist. Dominant traits are always written in capital letters. An example of dominants traits would be BB or Bb.
Recessive traits are traits that are only expressed if both of the alleles are recessive. A recessive trait is always written in a lowercase letter. An example of recessive traits would be "bb".
Also, Dominant traits are traits that are more common to people. It is strong. For example, if you are right handed, that is a dominant trait. Being right handed is a common thing in this world. 90% of the world's population is right handed.
On the other hand, recessive traits are traits that are rare to people. It is weak. For example, if you are left handed, that is a recessive trait. Being left handed is a rare thing for people in this world. Only 10% of the world's population is left handed.

_____ is used to find the gene that codes for a protein by matching amino acid sequences to codons, mRNA to cDNA, and cDNA to natural DNA.
Answer:
mRNA
Explanation:
This is because mRNA is a single stranded RNA molecule which is produced from the process of transcription and it's compliment one of the strand of DNA gene. They are made in the nucleus and later moved to the cell cytoplasm where translation occur. The RNA molecule is decided by RIBOSOMES during protein synthesis and it match amino acids to codons.
How many molecules of atp are needed for each "turn" of the calvin cycle
Answer:
3 ATP
Explanation:
Each turn of the Calvin cycle also uses up 3 ATP and 2 NADPH in the processes of reducing (adding electrons to) 3-phosphoglyceric acid to produce glyceraldehyde-3 phosphate, and regenerating RuBP so that they can accept a new atom of carbon from CO2 from the air.
9 molecules
*EXPLANATION*
the calvin cycle: three molecules of CO² fixed give a net yield of one molecule of glyceraldehyde 3-phosphat at the net cost of nine molecules of ATP and six molecules of NADPH
