Answer 1

Answer:

Compared to the use of many gasoline vehicles with only one person per vehicle, this method of transportation conserves more fossil fuels.

Explanation:

A form of transportation —such as the subway or streetcar— has capacity for many passengers and uses electricity as an energy source. This means fewer people using gasoline-vehicles, which leads to savings in fossil fuels, such as gasoline or diesel.

The decrease in the use of fossil fuels in vehicles has been proposed as an alternative to reduce environmental pollution and its consequences. One alternative is to consider mass transport vehicles that use alternative energy, a sustainable form of transport.

    None of the other options are correct, as they involve more or the same use of fossil fuels per person.

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.

Answers

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.

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?

Answers

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.

What is the effect of temperature on ATP,NADPH, and sugars? Will the increase, decrease, or stay the same?

Answers

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 decrease

ATP (  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.

Summarize the process of sexual reproduction and explain how variations of inherited traits can increase or decrease an organism’s chance of survival

Answers

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.

Answers

Answer:

Igneous — they form from the cooling of magma deep inside the earth. They often have large crystals (you can see them with the naked eye).

Metamorphic — they are formed through the change (metamorphosis) of igneous and sedimentary rocks. They can form both underground and at the surface.

Sedimentary rocks are formed when sediment is deposited out of air, ice, wind, gravity, or water flows carrying the particles in suspension. This sediment is often formed when weathering and erosion break down a rock into loose material in a source area.

When she looked at the cells under a microscope, she noticed that the cells in the leaf shrunk. Which statement best explains what caused the cells to shrink?

The hypertonic solution caused the water in the cell to move from the cytoplasm into the nucleus.
The salt moved from the hypertonic solution into the cell and chemically bonded with the water.
The salt within the cell moved through the cell membrane into the solution with the higher salt concentration.
The water within the cell moved through the cell membrane into the solution with the lower water concentration.

Answers

Answer:

The water within the cell moved through the cell membrane into the solution with the lower water concentration.

Explanation:

According to this question, a scientist removed the leaf of a plant originally grown in a freshwater aquarium and placed it in a hypertonic solution containing 8% salt. Firstly, A HYPERTONIC SOLUTION is that solution which contains a higher solute concentration than that of the intracellular environment.

Due to this concentration gradient i.e. difference in concentration, OSMOSIS process will be triggered. Osmosis is the movement of water from the region of low solute concentration (the leaf cells) to a high solute concentration (the salt solution) via a semi-permeable membrane (cell membrane).

Therefore, osmotic process causes water to move from the leaf cells into the salt solution via the cell membrane. hence, causing the cells of the leaf to shrink.

the difference between prokaryotic and eukaryotic gene regulation

Answers

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.
