True or False: The Calvin cycle is also known as the “light-dependent reaction” because it needs sunlight.

Answers

Answer:

false

Explanation: The Calvin Cycle, or light independent reaction, does not utilize sunlight as an input. During the light independent reaction, or the Calvin Cycle, carbon fixation first occurs. CO2 produced during the light dependent reaction reacts with RuBP, ultimately producing PGA.

Have a nice day!

False. The Calvin cycle is also known as the "light-independent reaction" because it does not require sunlight. The Calvin cycle is the process that plants use to convert carbon dioxide into glucose, and it takes place in the stroma of the chloroplasts. The light-dependent reactions, on the other hand, occur in the thylakoid membranes of the chloroplasts and require sunlight to produce energy in the form of ATP and NADPH, which are used to power the Calvin cycle.

What happens when a low air pressure system meets a high air pressure system?
A) The temperature of the air drops to below freezing.
B) The air moves to the low pressure system, creating wind.
C) The precipitation is removed from the air.
D) The air starts blowing in an easterly direction.

Answers

Answer:

High in the atmosphere, air pressure decreases. ... A low pressure system has lower pressure at its center than the areas around it. Winds blow towards the low pressure, and the air rises in the atmosphere where they meet. As the air rises, the water vapor within it condenses, forming clouds and often precipitation.

B) The air moves to the low pressure system, creating wind.

What is air pressure?

When a low air pressure system meets a high air pressure system, air from the high pressure system flows towards the low pressure system in an attempt to balance the pressure.

This movement of air creates wind. The stronger the difference in pressure, the stronger the wind. This is why wind speed is often stronger in areas with a large contrast in pressure, such as near fronts where a low pressure system meets a high pressure system.

How does the pacific ocean help explain the weather differences between San Francisco and Kansas city? If possible, discuss your answer.

Answers

The Pacific Ocean is near San Francisco, the high heat capacity of water absorbs large amounts of heat. The humidity in Kansas City is higher, water in the air absorbs heat which makes people feel more hot.

The presence of pacific ocean causes weather differences between San Francisco and Kansas city.

The pacific ocean helps in explaining the weather differences between San Francisco and Kansas city because San Francisco is located near the pacific ocean which has great effect on its climate while on the other hand, Kansas city is located far from the pacific ocean which have less or no effect on the climate of the Kansas city.

San Francisco has hot, dry summers and cool, rainy winters due to presence near the pacific ocean whereas the climate of Kansas City has cold winters and hot summers with frequent thunderstorms so we can conclude that the presence of pacific ocean causes weather differences between San Francisco and Kansas city.

What are three ways that genetic engineering is being used with animals? Give an example of each.

Answers

Genetic engineering in animals is used to enhance agricultural productivity. For example, scientists have genetically modified livestock such as cows and pigs to increase their growth rate or improve their meat quality. By inserting genes responsible for accelerated growth or enhanced muscle development, farmers can produce larger and more efficient animals for meat production.
Genetic engineering is also employed to create disease-resistant animals. Scientists have developed genetically modified mosquitoes with altered genes that make them resistant to certain diseases like malaria or dengue fever. These modified mosquitoes can help control the spread of these diseases by reducing the mosquito population that carries and transmits them.
Genetic engineering is utilized to produce pharmaceutical products using animals. This process, known as biopharming, involves genetically modifying animals, such as goats or rabbits, to produce specific proteins or antibodies in their milk or eggs. These proteins can then be harvested and used for the production of therapeutic drugs, vaccines, or other medical treatments.
It's important to note that the field of genetic engineering is vast and constantly evolving, and there are various other applications and examples of genetic engineering in animals beyond the ones mentioned above.

Answer: Genetic engineering is being used with animals in various ways.

Explanation:

Disease Research and Biomedical Applications: Genetic engineering enables the creation of animal models with specific genetic modifications to study diseases and develop potential treatments. For instance, scientists have created genetically modified mice that carry mutations associated with human diseases like cancer or Alzheimer's.

Agricultural and Livestock Improvement: Genetic engineering is employed in agriculture to enhance traits in livestock and improve agricultural productivity. For example, researchers have developed genetically modified pigs that are more resistant to specific diseases, such as Porcine Reproductive and Respiratory Syndrome (PRRS).

Conservation and Species Preservation: Genetic engineering has the potential to contribute to conservation efforts and species preservation. One example is the use of assisted reproductive technologies, such as in vitro fertilization (IVF) and embryo transfer, to help save endangered species.

How is genome editing being used in agriculture, genetics research, and medicine? What is an advantage of its use in each area?

Answers

Genome editing technologies, such as CRISPR-Cas9, are being used in a variety of fields, including agriculture, genetics research, and medicine. Here are some examples of how genome editing is being used in each area and an advantage of its use:

1. Agriculture: Genome editing is being used to develop crops that are more resistant to pests and diseases, have a longer shelf life, and are more nutritious. An advantage of using genome editing in agriculture is that it can be a more precise and efficient method of genetic modification compared to traditional breeding methods.

2. Genetics research: Genome editing is being used to study the function of genes and their role in various diseases. It can also be used to create animal models of human diseases, which can be used to test potential treatments. An advantage of using genome editing in genetics research is that it allows scientists to study the effects of specific genetic changes in a controlled environment.

3. Medicine: Genome editing is being used to develop new treatments for genetic diseases, such as sickle cell anemia and cystic fibrosis. It can also be used to modify immune cells to better target cancer cells. An advantage of using genome editing in medicine is that it has the potential to be a more targeted and precise method of treatment, which can lead to fewer side effects and better outcomes for patients.

Genome editing, is being applied across agriculture, genetics research, and medicine.

In agriculture, it allows modification of crop genomes to enhance yield, resistance to pests and diseases, and nutritional content, leading to increased food production and sustainability.

In genetics research, genome editing enables the study of gene function and disease mechanisms, accelerating the development of targeted therapies and advancements in medicines. In medicine, it offers the cure of genetic disorders by modifying disease-causing genes, previously untreatable conditions.

The advantage lies in improved crop productivity and sustainability in agriculture, accelerated genetic discoveries in research, and potential cures for genetic diseases, positively impacting global scientific understanding.

The interior of plantesimals originate as homogeneous (uniform) mixtures of molten material. Overtime, distinct layers form within plantesimals. Differentiation of Earth's layers did not need an outside force to begin this process. Rather, Earth's layers began separating soon after the planet formed. This process is similar to oil spills in oceans. When a spill first occurs, oil and ocean water are mixed. Over time, the less dense oil will float to the surface. Similarly, in early Earth, the more dense materials sank to Earth's core, and the less dense materials moved towards the surface. Eventually, layers became distinguishable because this process in effect sorted the materials of early Earth. Characteristics of these layers provide the evidence that a large object collided with Earth late in its development.
