Answer:

By crossing plants with purple flowers, dominant, with plants with white flowers the offspring will be 100% purple because all the offspring will receive at least one dominant allele.

Explanation:

The crossing of two plants of pure line, one dominant and one recessive, for a trait —the color of the flowers— will produce a hybrid offspring which will express the dominant trait in its phenotype.

Parental generation:

Cross: PP X pp

Punnett Square :

Alleles       P       P

p              Pp     Pp

p             Pp     Pp

Offspring: 100% Plants whose phenotype is purple flowers and Pp genotype.

According to this, the descendants will be 100% plants with purple flowers, hybrids, since all the offspring received at least one dominant allele.

Answer and Explanation:

During the whole biota history, there occurred extinctions due to different reasons.  

During the Cretaceous, which took place between 145-65 million years ago, there occurred a massive extinction that eliminated most of the species on the Earth. Many of the characteristic groups of this period were affected. Dinosaurs, Plesiosaurs, Ammonites, Tricodonts, Cycas, Gynkgos, Conifers, the recent angiosperms, birds, and mammals.  

The extinction was caused by the volcanic eruptions, and the unusual fall of many different asteroids, which caused important changes on the Earth´s surface. The consequent climatic change was what ended affecting all the species directly. The extinction was gradual, although it occurred in a short geological lapse of time.  

Answer:

Carbon Cycle

Everything You'll Have Covered

What role do producers, consumers, and decomposers play in the carbon cycle?

~ Producers synthesize their food through photosynthesis using energy from sunlight and carbon dioxide from the air. Their respiration returns carbon dioxide to the atmosphere. Consumers use the food produced by producers for energy. Their respiration also returns carbon dioxide to the atmosphere. Decomposers break down plant and animal waste products. They also break down dead plants and animals. The decomposing process releases carbon dioxide gas into the atmosphere.

How do fossil fuels and volcanic activities contribute to the carbon cycle?

~ When fossil fuels are burned, carbon dioxide is released into the atmosphere in the form of gas. When volcanoes erupt, carbon dioxide that was in the magma passes into the atmosphere as carbon dioxide gas.

How is carbon returned to the Earth and sea in the carbon cycle?

~ Carbon is returned to the Earth and sea in the form of precipitation after carbon dioxide mixes with rain and snow. Erosion is another way that carbon is returned to the sea. When shellfish die, the carbon that was in their shells collects at the bottom of the ocean and eventually forms sedimentary rocks.

Give one example of a human activity�that could disrupt the�carbon�cycle�as well as the consequences of this disruption.

~ Burning fossil fuels can disrupt the carbon cycle, since they increase carbon dioxide in the air, which can lead to environmental problems such as acid rain.

Photosynthesis is the process by which plants produce their food in the presence of sunlight that is solar energy with the use of carbon dioxide and water. The breakdown is the mechanism  by which plants give their carbon dioxide back.

The end products of photosynthesis are glucose and oxygen that is given back to the atmosphere.

In plants, photosynthesis is the process by which plants prepare their food in the presence of sunlight and glucose is made thus this is the way by which plants are preparing their food and in the case of plants glucose is stored in the form of starch.

With the reactions going on when the cellular respiration reactions are going on at that time the reactions produce enough of carbon dioxide which is given back to the atmosphere thus this dependency helps to interpret the mutual relationship.

Overview of answer:

-First, your digestive system is involved in the hunger pains you feel because your stomach is empty and your body needs more energy.

(-Since you are alive and breathing, your respiratory system is also involved.)

-Getting up involved the muscular and skeletal systems, which allow movement and bodily structure, and the nervous system, which commands the muscles and bones to move.

-Eating and drinking involves the digestive system again as saliva and enzymes break down the food travelling from the mouth to the stomach.

Explanation:

I think that is all involved but there may be more depending on how you look at it. Hope this helps! :)

Digestive system is involved in the hunger pains you feel because your stomach is empty and your body needs more energy.

The human digestive system consists of the gastrointestinal tract plus the accessory organs of digestion. Digestion involves the breakdown of food into smaller and smaller components.

he digestive system breaks down food into nutrients such as carbohydrates, fats and proteins.

They can then be absorbed into the bloodstream so the body can use them for energy, growth and repair. Unused materials are discarded as faeces.

Nitrogenous base

Explanation:

Phosphate and deoxyribose create the "backbone" of a DNA molecule.

Think of the molecule as a ladder.

These(deoxyribose and phosphate) are the sides of the latter.

The nitrogenous bases(A,G,C,T) are the rungs of the ladder.

As the arrow points to the "rung" of the ladder, that means it is a nitrogenous base.

Explanation:

Answer:

The two problems that the transfer of information from DNA to protein must overcome are:

Explanation:

The genetic information is found in the DNA and depends on a specific sequence of nitrogenous bases. This information is transcribed into the messenger RNA, whose base sequence is organized into triplets and codons, each of which encodes an amino acid, as well as establishing the pattern for starting and stopping the synthesis of a protein.

The DNA must be transcribed into messenger RNA (mRNA), a process that occurs in the nucleus of the cell. mRNA leaves the nucleus and travels to the cytoplasm, where amino acid synthesis will take place.

Once in the cytoplasm mRNA binds to ribosomes, structures in charge of translating the sequence of nitrogenous bases RNA to synthesize amino acids. The set of ribosomes and rough endoplasmic reticulum are in charge of the assembly of amino acids to produce peptides and proteins.

Answer:

The functions of nucleic acids have to do with the storage and expression of genetic information. Deoxyribonucleic acid (DNA) encodes the information the cell needs to make proteins. A related type of nucleic acid, called ribonucleic acid (RNA), comes in different molecular forms that participate in protein synthesis.

Explanation:

The most important function of the nucleic acids is to store and express the genetic information of the cell in the form of DNA (deoxyribonucleic acid).

Nucleic acids are the naturally occurring biochemical compounds which serve as the primary information-carrying molecules in the cells.
