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.

Cellular respiration is called an aerobic process because it requires _______________.

Answers

Answer:

Cellular respiration is called an aerobic process because it requires oxygen and carbon dioxide.

Explanation:

Hey There!_____________________________________Answer:[tex]\Huge\boxed{\text{Oxygen}}[/tex]_____________________________________[tex]\Huge\textbf{Cellular Respiration}[/tex]

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.

[tex]\Large\textbf{Cellular Respiration Equation}[/tex]

[tex]\text{C_6H_12O_6}/ + \text{6O_2} {\Longrightarrow}[/tex][tex]{C_6H_{12}O_6}\ + {6O_2}\ {\longrightarrow}\ 6CO_2\ +\ 6H_2O\ (ATP\ +\ Heat)[/tex]

_____________________________________[tex]\Huge\text{Aerobic and Anaerobic Respiration}[/tex]

[tex]\texttt{(i)}[/tex] Aerobic Reaction: Aero = air, bic = life and Respiration.

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,

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.

What is the difference between dominant and recessive traits? ​

Answers

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.

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.

Answers

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.independent assortment
B.crossing over
C.anaphase 1 of meiosis
D.incomplete dominance

Crossing over is the exchange of chromosome segments between non-sister chromatids during the production of gametes.
