What is one reason scientists are trying to culture meat in laboratories instead of simply hunting or raising animals?
Answers
Answer:
Many reasons - but a really good question.
Explanation:
Cruelty - eating meat poses ethical issues to some people. They dont eat meat because they dont believe animals should be harmed. Growing laboratory meat takes away the need for slaughter.
Land used - a big issue with producing meat is the amount of land we need to raise cattle and to grow the food to feed cattle. Rainforest, woodlands, moorland have to be destructed to make way for pasture land for cattle. The food that cattle or animal eats also needs to be grown, which requires more land. Laboratory grown meat doesnt require all the pasture space for raising or feeding animals.
Water use - the amount of water that goes into producing meat is very high when compared to amount of meat that you get back. Water availability is another global issue that may be able to be addressed by lab produced meat.
When animals are reared from meat, they may be killed in unethical ways thereby making it ethically irresponsible to raise animals for meat.
Animals are widely used as food. This food from animals or having animal origin is known as meat. The ethical issues are of key importance in raising meat for food.

true or false: the three protective membranes that line the cranial cavity and vertebral canal are the mesenteries.
Answers
The three protective membranes that line the cranial cavity and vertebral canal are the mesenteries. This statement is false because mesenteries are the fold of membrane which attaches the intestine to the abdominal wall and helps to hold it in place.
Although Meninges are the three layers of protective membranes that protect cranial cavity and vertebral canal or the brain and spinal cord.
Therefore, three protective membranes that line the cranial cavity and vertebral canal are the Meninges which main function is to to protect the central nervous system (CNS) and give protection to the brain and spinal cord. Also it ensure the tight anchoring of the CNS to surrounding bones, and provide stability.

Answers
Micro-scale changes refer to morphological or physycal changes in individuals or objects, and are ussually related to micro-scale changes, sucha as mutations that are molecular changes. I agree with the statement. Example: mutations.
What is a change at macro-scale?Changes at the macro-scale refer to morphological traits or physical characteristics that can be seen and recognized in individuals or objects by looking directly at them.
These changes are related to other changes or random events that occurred at a micro-scale level (molecular level) that might produce or cause a cascade effect leading to the expression of a different trait.
These are for instance mutations.
Mutations are alterations in the original nucleotidic sequences of the DNA molecule. These changes code for different amino acids. They might cause a change in the protein synthesized and hence a change in the phenotype.
The answer to the question is Yes. I agree with the statement “A change that can be observed at the macro-scale can be explained by a change at the molecular scale.”

“Some viruses are programmed to reproduce by identifying bacteria, killing them, and assembling new viruses.viruses do not eat the bacteria and do not grow after they are made. Viruses are not alive. Explain two reasons why.”
Answers
1. Viruses cannot reproduce on their own: Unlike living organisms, viruses cannot reproduce on their own. They need to infect a host cell and hijack the host cell's machinery in order to replicate themselves. Once they have infected a host cell, they use the cell's energy and resources to create new copies of themselves. However, they do not have the ability to reproduce outside of a host cell.
2. Viruses do not have the ability to carry out metabolic processes: Living organisms carry out metabolic processes, such as respiration and digestion, in order to obtain energy and nutrients. Viruses do not have the ability to carry out these processes on their own. They rely entirely on the host cell to provide them with energy and nutrients. In fact, viruses do not even have the necessary machinery to carry out these processes. They lack the organelles, such as mitochondria, that are responsible for energy production in living cells.

Which complex carbohydrate has 3 to 10 simple sugar units and cannot be broken down by the body's digestive enzymes
Answers
Oligosaccharides are complex carbohydrates that have 3 to 10 simple sugar units and cannot be broken down by the body's digestive enzymes. They are complex carbohydrates.
Oligosaccharides, complex carbohydrates and enzymesOligosaccharides are complex carbohydrates composed of three or more monosaccharides (e.g., glucose and fructose) or the union of two or more disaccharides (e.g., lactose).
Humans cannot digest these oligosaccharides because we don't have digestive enzymes such as ⍺-galactosidase, thereby they cannot be hydrolyzed.
Complex carbohydrates are in turn long chains (either branched or unbranched) of monosaccharides linked by glycosidic bonds.
A well-known example of complex carbohydrates (polysaccharides) is starch, which is composed of many subunits of glucose.
Enzymes that break down complex carbohydrates must have the ability to break glycosidic bonds.

Which of these molecules is polar?
Which of these molecules is used for short-term energy storage?
Answers
The polar molecule is water (H2O) and the molecule used for short-term energy storage is glucose (C6H12O6).
Water is a polar molecule because it has a slight positive charge on the hydrogen atoms and a slight negative charge on the oxygen atom due to the unequal sharing of electrons. This creates a dipole moment, making the molecule polar.
Glucose is a simple sugar that is stored in the liver and muscles as glycogen and is broken down into energy through the process of glycolysis. It is used for short-term energy storage because it can be quickly converted into energy when needed.

Answers
Answer:
B. refraction
Explanation: hope this helps!
The shadow zone exists due to the effect of seismic waves is the refraction. Thus, the correct option will be B.
What is Refraction?Refraction can be defined as the redirection of a wave as it passes from one medium to another medium. The redirection of the waves in a medium can be caused by the wave's change in speed or by a change in the medium of wave.
Seismic waves are the waves which follow the same law of refraction at the compositional boundaries. If the seismic wave velocity in the rock below a boundary is increasing then, the waves will be refracted in the upward direction and this speed up relative to their original path of movement.
Therefore, the correct option will be B.

the rate at which materials enter and leave the cell depends on the cells
Answers
Answer: the answer is the surface area
Explanation: The increase in the radius of the cell will cause an increase in the area of the cell.
The larger the area of the cells, the faster will be the rate of diffusion. The rate at which materials are exchanged will be increased.
The increase in the cell size, however, causes a decrease in the area-to-volume ratio, which will result in efficient diffusion.
Thus, the surface area of the cell and its volume play a crucial role in the exchange of material with the surrounding.

what was the problem with reusing contaminated water from other parts of the mill to extinguish the coke fires? From the book ‘When smoke ran like water’
Answers
Answer:
1. The problem with that was that the already poisonous water was made worse after using it to quench the flames from coke production.
2. It contaminated the soil, making it difficult for plants to grow.
Explanation:
As the author described the last stages of coke production, she explained that water was needed to quench the very hot flames from coke production. A 'bright fellow' suggested using dirty water from other parts of the mill to quench the flames from the coke production. The problems with this were;
1. The already contaminated water was made worse after it was used to quench the flames from coke.
2. Mrs. LaMendola noted that she was unable to grow her tomatoes in the path where the plumes from the oven ran. So the contaminated water negatively affected the soil.
The problem that should be already poisonous water is also made worse when it quenches the flames at the time when the production of the coke should be done.
Also, it contaminated the soil also it is difficult for growing the plants.
The problem of reusing contaminated water:Since the author explained the last coke production stage so here the water required to quench that it should be very hot flames arise from the coke production. Also, the contaminated water should be worse whenever it is used for quenching the flames. Also, the contaminated water does not positively impact the soil.

An example of epistasis can be observed in the group of answer choices where in rabbits and many other mammals, one genotype (ee) prevents any fur color from developing.
**Epistasis** is a type of gene interaction where one gene masks or modifies the expression of another gene. In the case of rabbits and many other mammals, the genotype "ee" prevents any fur color from developing, even if the genes responsible for fur coloration are present. This is an example of recessive epistasis, where a homozygous recessive gene (ee) masks the expression of other genes. In contrast, the albino corn snake is an example of recessive gene interaction, and the white eyes in drosophila can be due to a combination of other genes or an X-linked gene.
