Answer:
True
Explanation:
Organic matter in the soil is called "humus". It is formed by the decomposition of plant material by microorganisms.
It is extremely important for retaining water and nutrients in the soil, both of which are crucial for plant growth and survival. Therefore, organic matter in the soil makes the soil much more "productive."
One side of the water molecule has a positive charge, while the other side has a negative charge. What do the charges indicate about the molecule?
Answer:
That its a nuetral
Explanation:
In the given case of water molecule, the charges shows that it is a polar molecule.
What is a polar molecule?It is a molecule in which one terminal of the molecule is slightly positive and the other terminal is slightly negative. In the case of water molecule, the unequal sharing of electrons provides the molecule with a slight negative charge close to its oxygen atom and a slight positive charge close to its hydrogen atoms.
When a neutral molecule, possesses a positive region at one terminal and a negative region at the other, it is considered as a polar molecule. The molecules of water attract each other on the basis of the positive end of one water molecule and the negative end of the other molecule of water.
Thus, the charges shows that it is a polar molecule.

How can you decrease your height in under a week?
A scientist crossed two fruit flies in a lab. She was studying the transmission of the alleles that affect wing shape. The dominant allele, C, is the allele for curly wings, and the recessive allele, c, is the allele for straight wings. She knew that one of the parent flies was heterozygous and had curly wings (Cc). Half of the offspring from the cross had curly wings, and the other half had straight wings. Identify the genotype and phenotype of the second parent fly. State the evidence that supports your response.
Answer:
The other fly would have to be a cc
Explanation:
To do this, you can use the square method, one Cc's on the top and one side a cc, when you cross these it gives you Cc, Cc, and cc, cc. Half and half.
Hope this helped!
The other parent was cc.
Genes often occur in pairs. Genes are units of inheritance located in the chromosomes. The pairs in which genes occur are called alleles. In a given pair of alleles, one gene is dominant and the other is recessive.
In this case, the dominant gene is for curly wings and the recessive gene is for straight wings. If one parent is Cc , the other parent must be cc causing half of the offspring from the cross to have curly wings, and the other half to have straight wings.

What is the effect of temperature on ATP,NADPH, and sugars? Will the increase, decrease, or stay the same?
Answer:
1. ATP will increase
2. NADPH will increase
3. Sugar will decrease
Explanation:
Had the same problem
The effect of temperature on these molecules are ;
ATP will increase NADPH will also increase while Sugars will decreaseATP ( Adenosine triphosphate ) is the molecule in cells which stores energy in cells while transferring the energy needed within cells as well. When the temperature of a cell is raised above the required temperature this molecule will also increase in response.
NADPH is an electron donor which is found in organisms, it also provides the reducing power for certain reactions in the organism ( anabolic ) and the gathering of NADPH oxidase. increases as the temperature of the organism increases.
Hence we can conclude that as temperature increases , ATP will increase , NADPH will increase while Sugars will decrease.

the difference between prokaryotic and eukaryotic gene regulation
Answer:
READ THIS
Explanation:
To understand how gene expression is regulated, we must first understand how a gene codes for a functional protein in a cell. The process occurs in both prokaryotic and eukaryotic cells, just in slightly different manners.
Prokaryotic organisms are single-celled organisms that lack a cell nucleus, and their DNA therefore floats freely in the cell cytoplasm. To synthesize a protein, the processes of transcription and translation occur almost simultaneously. When the resulting protein is no longer needed, transcription stops. As a result, the primary method to control what type of protein and how much of each protein is expressed in a prokaryotic cell is the regulation of DNA transcription. All of the subsequent steps occur automatically. When more protein is required, more transcription occurs. Therefore, in prokaryotic cells, the control of gene expression is mostly at the transcriptional level.
Eukaryotic cells, in contrast, have intracellular organelles that add to their complexity. In eukaryotic cells, the DNA is contained inside the cell’s nucleus and there it is transcribed into RNA. The newly synthesized RNA is then transported out of the nucleus into the cytoplasm, where ribosomes translate the RNA into protein. The processes of transcription and translation are physically separated by the nuclear membrane; transcription occurs only within the nucleus, and translation occurs only outside the nucleus in the cytoplasm. The regulation of gene expression can occur at all stages of the process (Figure 1). Regulation may occur when the DNA is uncoiled and loosened from nucleosomes to bind transcription factors (epigenetic level), when the RNA is transcribed (transcriptional level), when the RNA is processed and exported to the cytoplasm after it is transcribed (post-transcriptional level), when the RNA is translated into protein (translational level), or after the protein has been made (post-translational level).
Answer:
Prokaryotic gene expression is primarily controlled at the level of transcription. Eukaryotic gene expression is controlled at the levels of epigenetics, transcription, post-transcription, translation, and post-translation.

Cytoplasm contains the cytosol, microfilaments and other support structures in the cytoskeleton; it holds parts of the cell together.
What is cell wall?Cell wall is the rigid outer layer of the cell; this forms a protective wall made mostly of cellulose, a structural carbohydrate. It maintains the shape of the cell by preventing water loss. Vacuole a phospholipid membrane bound organelle plays a structural role in the cell; supports the cell membrane by exerting turgor pressure.
Arranged in a phospholipid bilayer, the cell membrane is semi-permeable; allowing entry into the extracellular fluid or the cytoplasm which are both hydrophilic and contain large concentrations of polar water molecules or other water-soluble compounds.
The hydrophilic heads of the bilayer are attracted to water while their water-repellent hydrophobic tails face towards each other- allowing molecules of water and hydrophilic molecules to move across the membrane along the concentration gradient.
Therefore, Some organelles are bound by membranes like those that make up the external structure of the cell, with varying compositions of phospholipids and proteins.

Explanation:
Plz help!! I need help
Answer:
a} Allosteric regulation is just any form of regulation where the regulatory molecule (an activator or inhibitor) binds to an enzyme someplace other than the active site.The shape of the active site is changed, allowing substrate to bind at a higher affinity.
b) The molecules that bind cellular respiration enzymes act as signals, giving the enzyme information about the cell's energy state. ATP, ADP, and NADH are examples of molecules that regulate cellular respiration enzymes. ATP, for instance, is a "stop" signal: high levels mean that the cell has enough ATP and does not need to make more through cellular respiration.
c) This is a case of feedback inhibition i in which a product feeds back to shut down its pathways.

Summarize the process of sexual reproduction and explain how variations of inherited traits can increase or decrease an organism’s chance of survival
Answer:
Explanation:
A Human cell has 46 chromosomes. (I’ll use humans to keep things simple). In sexual reproduction both humans have 23 chromosomes, in their sex cells. (Men have 23 in a sperm and women have 23 in an egg cell). These half cells merge to create 1 unique cell, that has characteristics of both male and female. The cells multiply and then a baby is born with a unique set of genes. These cause variations, and remember these variations can carry from generation to generation. As for how variations can increase a chance for survival, variations allow unique gene sets to be made, so that in case of a disease (in this case I’ll use a disease, but it could also include harsh environmental conditions), these unique gene sets may give an individual natural immunity to the disease. How can a variation decrease an organisms chance for survival? Well, s there are many ways that a unique gene set can make it difficult to survive. For example a genetic disease your family has had a history with. These diseases include, but are not limited to, cancer, diabetes, and schizophrenia.
