6.It results in daughter cells with the haploid number of chromosomes.
Please help we are doing a test aint i have no idea
Answer:
It results in daughter cells with the haploid number of chromosomes.
Explanation:
Before meiosis, DNA replication occurs in the diploid parent cells.
Then, the first round of meiosis (i.e. cell division) occurs. This creates two daughter cells, each with a diploid genome. Then, a second round of meiosis occurs in each cell, pulling apart the chromosomes and creating two haploid cells from each cell, resulting in a total of four haploid cells.
When these haploid cells participate in fertilization, they fuse with another haploid cell (e.g. an egg and sperm are both haploid and fuse) to make the zygote. This restores the diploid state so that every cell in the new organism is diploid.

Where is carbon located on our planet, and how are these carbon reservoirs different from each other?
Which reservoir of the carbon cycle changes the most and the quickest?
What are the main differences between the carbon flows 300 years ago and today?
Compare the Illustration View and the Chart View of carbon flows into and out of the atmosphere. Why is it helpful to see two different models to explain the same situation?
Over the past 300 years, how did the role of the ocean change with respect to the amount of carbon dioxide in the atmosphere?
What has happened to atmospheric carbon dioxide level and global temperature since the graph in the interactive, which was created in the year 2014?
Explanation:
carbon C,, comes from burning of hydrocarbons ,,which is a component of oxygen hydrogen and carbon ,,,the reservior in which carbon changes is coke,,,carbon flow into the atmosphere is less than the one released and these causes global warming,,due to blockage of the ozone layer leading to rain acid which leads to corrosion of iron,,,,over 300 years the role of ocean has changed,the convectional currents from the see meets carbon due to oxidation,,Co is formed C +O=C0,, ,in 2014,,the rate of global warming increased due to imcrease of release of carbon to the atmosphere,,,
What is another term for the manipulated variable?

What is the reactant of lactic acid fermentation and the product that builds up during exercise?
A) oxygen and lactic acid
B) carbon dioxide and water
C) Glucose and other compounds
D) glucose and lactic acid
Answer:
gotta be D or A but D is more reasonable
D) glucose and lactic acid
Homolactic fermentation also occurs in muscle cells and results in the formation of two molecules of lactic acid from the breakdown of the reactant.Glucose is the simple sugar reactant used in this type of homolactic fermentation, instead of lactose used in the case of bacteria. The reactants are pyruvate, NADH and a proton. This process of energy production is employed by muscle cells when oxygen levels are low, such as during periods of extreme exercise. The lactic acid end product is also one of the factors responsible for muscle soreness after exercise.Thus, reactant is glucose while product is lactic acid for lactic acid fermentation.Therefore, the correct option is D.

Which of the following statements correctly describes the process of GPCR signaling?
The GPCR activation is reversible after the signal of the ligand diminishes.
O The membrane-embedded enzyme uses GTP as a secondary messenger to initiate gene expression.
O The ligand attaches to both the GPCR and the membrane-embedded enzyme to activate the GPCR pathway.
O The ligand-bound GPCR sends a GTP molecule to an enzyme in the membrane and switches it into an active
state.
Answer:
B) The membrane-embedded enzyme uses GTP as a secondary messenger to initiate gene expression.
Explanation:
Due to the fact G Protein Coupled Receptors (GPCRs) perceive many extracellular signals and transduce them to heterotrimeric G proteins, which further transduce these signals intracellular to appropriate downstream effectors and thereby play an important role in various signaling pathways
If im wrong so be it >:)
Answer:
b
Explanation:
PCRs are a large family of cell surface receptors that respond to a variety of external signals. Binding of a signaling molecule to a GPCR results in G protein activation, which in turn triggers the production of any number of second messengers.
what are inputs and outputs of a cell cycle ?
Answer:
Glycolysis input and output .
Glycolysis input and output .Kerbs Cycle input and output
Explanation:
Glycolysis output : 2ADP+P , NAD+4
-ATP, 2 PYRUVIC ACIDS
Glycolysis input : 2 ATP, NAD+ 4
ATP, NAD+ 4 - ADL+P , GLUCOSE
Kerbs input : CoA, NAD+ acetyl acids
CoA, NAD+ acetyl acids - 2NAD+, ADP+P , FAD , NAD
Krebs output :CO2, NADH, CoA2
-NADH ,ATP ,FADH
-NADH , 4 C - molecules
Glycolysis is the input and Krebs Cycle is the output of the cell cycle.
What is glycolysis ?
Glycolysis has been known as first step of cellular respiration. During this process glucose molecules break down in order to form pyruvate molecules including 2 ATP molecules. During the process of glycolysis there has no requirement of the oxygen. Hence, the process has been known as anaerobic process.
During the process of glycolysis glucose has been converted into pyruvic acid and energy has been released for the formation of high energy molecule. Glycolysis has been known as the first step in cellular respiration and during this process aerobic 6 - carbon glucose forms three 2- carbon pyruvates, forms a net total 2 ATP.

Explain incomplete dominance, using snapdragon flowers as an exmaple
Answer:
when a dominant allele, or form of a gene, does not completely mask the effects of a recessive allele, and the organism's resulting physical appearance shows a blending of both allele
Explanation:
Cross-pollination between red snapdragons and white snapdragons result in pink when neither the white or the red alleles are dominant.
Answer:
Sample Answer:
Incomplete dominance is seen in offspring that have a third phenotype not seen in the parents. Snapdragons are an example. The third phenotype results when a snapdragon with the red pigment protein crosses with a snapdragon with a defective gene that produces no pigment, resulting in a white snapdragon. The offspring receive one allele from each parent, resulting in half the amount of pigmentation for red color being expressed. The offspring will be pink snapdragons instead of red or white.
