Answer:
energy is lost in the food chains so many secondary consumers cannot be supported
In 2012, excitement rippled through the scientific community with the discovery of an enzyme that appeared to be, just maybe, a powerful new tool for combating Alzheimer’s. At the Mayo Clinic in Florida researchers identified a gene, BACE2, which appeared to destroy beta-amyloid — a protein, then understood to be toxic, which is found in clusters in the brains of people living with Alzheimer’s. Alzheimer's is often diagnosed by measuring the amount of buildup of this protein. A large amount of it is an indicator of the disease. People with this buildup often do not have enough of the BACE2 enzyme created naturally in their body. If a way to synthesize this enzyme artificially or to prompt the body to create more were discovered, it could be hailed as a cure for Alzheimer's. How does the BACE2 enzyme work?
Answer:
BACE2 cuts both beta-amyloid and beta-amyloid precursor protein.
Explanation:
What makes BACE2 so effective in fighting Alzheimer's is its efficiency in cutting both beta-amyloid and the protein that develops it. There are other enzymes, which have the ability to break down beta-amyloid, but BACE2 is the only one that breaks it down into such small pieces that it completely destroys it. Furthermore, BACE2 is able to break down the beta-amyloid precursor protein, which prevents the formation of beta-amyloid from taking place.

Which process comes first in the process of protein synthesis?
A. Transcription
B. Translation
Answer:
A. Transcription
Explanation:
Transcription comes first in the process of protein synthesis.
Answer:
A.Transcription
Explanation:
Transcription is the process of making an RNA copy of a gene sequence. This copy, called a messenger RNA (mRNA) molecule, leaves the cell nucleus and enters the cytoplasm, where it directs the synthesis of the protein, which it encodes.

How has the human population grown in the last 200 years? Why has human population growth accelerated in the last 200 years?
Answer:
1. The size and growth rate of the human population has changed in the past 200 years because reproduction rates have increased due to the large number of people in the world. 2. Human population has grown exponentially over the past century. It has done so largely by producing large amounts of food, and learning how to control disease. Ten thousand years ago, when humans first invented agriculture, there were maybe one million humans on the planet.

B. Bacterial populations in hospitals develop resistance to drugs used to combat infection by them.
C. Scientists breed cows that give greater amounts of milk than their ancestors.
D. Fruit fly larvae with an enzyme to break down alcohol are better able to feed on fermenting fruit than those that lack the enzyme.
E. Female fish that produce more eggs leave more offspring than those that produce fewer eggs.
Answer:
The Answer is C
Explanation:
When scientists breed cows to produce more milk, this has not occured naturally and thus is not natural selection.
Answer:
C. Scientists breed cows that give greater amounts of milk than their ancestors.
Explanation:
The scientists breed cows that give greater amounts of milk than their ancestors is not an example of natural selection. So, option (C) is correct.

Which organism, roadrunner or the owl, competes more for its food?
Support your answer with evidence from the food web.
The roadrunner and the owl are both predators and compete for similar prey, such as small mammals, birds, reptiles, and insects. However, the extent to which they compete for food depends on various factors such as their habitat, size, behavior, and hunting techniques.
What do you mean by predators ?
Predators are animals that hunt, kill, and consume other animals (known as prey) for their sustenance. Predation is a common form of interaction between different species in many ecosystems. Predators come in many different forms, such as mammals, birds, fish, insects, and reptiles.
Predators are typically characterized by certain physical and behavioral adaptations that help them hunt and capture prey. For example, many predators have sharp teeth, claws, or beaks that are used to kill and consume their prey. Others may have specialized hunting techniques or strategies that make them highly effective predators.
The roadrunner and the owl are both predators and compete for similar prey, such as small mammals, birds, reptiles, and insects. However, the extent to which they compete for food depends on various factors such as their habitat, size, behavior, and hunting techniques.
Roadrunners are known to be opportunistic hunters and can feed on a wide range of prey items. They are ground-dwelling birds and use their speed and agility to catch their prey. Roadrunners are also known to eat eggs and young of other birds, including owls.
Owls, on the other hand, are nocturnal predators that are known for their exceptional hearing and vision, which enables them to hunt in low light conditions. They are also skilled hunters and can catch a variety of prey, including rodents, small mammals, and birds.
Therefore, both roadrunners and owls are capable of competing for food, but the level of competition depends on the availability of prey, habitat, and other factors. In general, the competition between these two species is likely to be limited, as roadrunners are diurnal (active during the day) and owls are nocturnal (active at night).

Discuss how a soil, a natural body, differs from soil, a
material that is used in building a roadbed.
Answer:
Soil is a material made up of gases, organic substances, water, and microorganisms. This material may be used in building a roadbed and is often referred to as dirt. In comparison, a soil is a natural body that is three-dimensional much like a lake or mountain.
Explanation:
Hope this helps
Gases, organic materials, water, and microbes are all components of soil. This substance, which is frequently referred to as dirt, can be utilized to construct a roadbed. In contrast, the soil is a three-dimensional natural structure similar to a lake or a mountain.
What is soil?Soil is the loosely packed organic or mineral material that makes up the Earth's immediate surface and acts as a habitat for land plants. The unconsolidated organic or mineral matter that has been exposed to relief-conditioned macro- and microbes operating on parent material throughout time, as well as genetic and environmental factors such as climate (including water and temperature effects). A product-soil is distinct from the source material in many ways, including in terms of its physical, chemical, biological, and morphological qualities.This is how natural soil is different from the material used in constructing roadbeds.

[answer2] what is the RNA sequence of the 3' UTR [answer3]
Answer:
- Protein sequence: Met-Pro-Gly-Lys-Ile-Arg-Arg-Pro-Pro-Gly-Thr-Pro-Leu-Phe-Gly-Lys-*
- DNA 5' UTR: ATTTTAGCC
- RNA 3' UTR: UAAAAAUAAAAU
Explanation:
Transcription is the process in which a DNA sequence (e.g., a gene) is used as template (transcribed) in order to synthesize an RNA molecule, usually a messenger RNA molecule, which is then used as template to produce a polypeptide sequence (protein) in the ribosomes. In RNA, Thymine (T) bases are always replaced by Uracil (U) bases. An mRNA strand is formed in the 5′ to 3′ direction. Each triplet of nucleotides is referred to as a codon and the resulting mRNA strand is translated starting from codon AUG (Methionine), while there are three different stop codons or 'or termination codons' in the genetic code that terminate translation: UAG, UAA, and UGA.
Which organism in the food web below is likely to store the most energy?

coati
poison dart frog
sloth
strangler fig
fungus
fruit bat
A. Strangler fig
B. Boa constrictor
C. Beetle
D. Poison dart frog
Answer:
Beatle
Explanation:
Beetle in the food web below is likely to store the most energy. So, the correct option is (C).
What is Food Web?A food web is defined as the natural interconnection of food chains and is a graphical representation of what-eats in an ecological community. Food web is also known as consumer-resource system.
A food web consists of many food chains while a food chain follows only one path as animals find food. For example, Falcon eats snake, which has eaten frog, which has eaten grasshopper, which has eaten grass. Thi shows the many different pathways that plants and animals are connected.
In this, the lower trophic level organisms have more energy than the upper trophic level because only 10% of the energy flows from one trophic level to the next. In the above case, beetles have the highest energy compared to other organisms.
Thus, Beetle in the food web below is likely to store the most energy. So, the correct option is (C).
