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.

Photosynthesis is done only by plants by using sunlight water and CO2
All living organisms can do cellular repirations
She is wrong because she said plants only do photosynthesis but that's not true because trees do cellular repiration too because when there is no sunlight they need energy. So what they do is they break down the sugar doing glycolysis by using mitochondria. Sidenote:Both plants and animals have mitochondria in their cells.They need energy right when there is no sun.So they use glycolysis.Glyco means sugar and lysis means break down.Then there come 2 steps.
Aerobic Respiration
Anaerobic Repiration
If the sugar that we just break down contains oxygen the that sugar falls to the aerobic respiration
If it does not contain sugar it goes to Anaerobic Respiration
Aerobic Respiration : It would use Kreb Cycle to Make 2 ATP.ATP is for Adension Tri Phosphate. Which is basically enregy.Then there comes Electron Transport Chain.Where they use protons to gain 32 ATP.Overall
2 ATp from glycolysis 2 from Kreb Cycle and 36 from ETC so 36
Anerobic: They fall part to 2 major respirations of this section which are
1. Alcoholic Repiration - It contains no oxygen, gain 2 atp and used to make breads and alcohol
2.Lactic Acid - gain 2 ATp and no oxygen and used in yogurt you eat and it creates sore in your muscles
She is wrong because that is completely wrong statement that trees only do photosynthesis but no they use cellular Respiration to gain energy from ATP when there is no sun available to them

_____ 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.

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.

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

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.
