If scientists wanted to engineer a bacterium that could triple the digestion of lactose in the operon, which parts might the scientist add/subtract?

Answer:

NH4+ and aspartate are the two molecules of the urea cycle contribute these two nitrogen.

Explanation:

Two nitrogen-containing groups are used to make urea in liver cells. The nitrogen atoms enter the urea cycle as NH4+ and aspartate. The first step of the urea cycle take place in liver mitochondria. In liver mitochondria, NH4+ combines with HCO3- to form carbamoyl phosphate.

So,

NH4+ and aspartate are the two molecules of the urea cycle contribute these two nitrogen.

Ammonia and aspartate are the two molecules of the urea cycle contribute

these two nitrogen used in the formation of urea.

These compounds are produced in the liver through the breakdown of

amino acids in the liver. The amino acids undergo transamination and

deamination reactions which results in the formation of these compounds.

The ammonia which is highly toxic is converted into urea which is then

excreted from the body.

Answer:

The pH will be very High.

Explanation:

The electron chain is responsible for generating the Proton Motive Force, which pumps H+ (protons) into the inter membrane space, to lower the pH.Therefore if Cyanide inhibits the ETC, the PMF will be stopped.

Hydrogen ions will not be pumped into the inter-membrane space,to lower the pH  of the medium for increase acidity. Hence, electrochemical gradient from the diffusion of H+ back into the matrix will not  be generated,

Energy for ATP synthesis by ATPase Enzyme will not be produced. Therefore ATP synthesis will stop.

The phylum with the greatest number of different species: Generally, the Phylum Arthropoda (which includes insects, spiders, and crustaceans) has the highest number of species globally.

The most difficult phylum to find: This would depend on the specific region and habitat. Some phyla like Porifera (sponges) or Echinodermata (starfish, sea urchins) might be hard to find in a terrestrial environment because they're primarily marine.

Phyla you could not find at all: This again would depend on your location. If you're not near a body of water, you're unlikely to find any members of the Phylum Cnidaria (jellyfish, corals, sea anemones) or Phylum Mollusca (squid, octopus, snails) for example.

Animal diversity: Diversity varies greatly depending on the region. Biodiversity hotspots, such as rainforests or coral reefs, have a high level of species diversity. Conversely, more extreme environments like deserts or polar regions have less diversity.

What is natural selection?

Darwin employed natural selection for the first time. He discussed the parallels and differences between the various creatures. These differences are sometimes referred to as variety. The process by which nature chooses the most adaptable and compatible organisms for evolution is known as natural selection. The organisms in nature face some difficulties. Climate change, food insecurity, and natural disasters including earthquakes, floods, and lightning are a few examples of these difficulties.

Answer:

Scientific Theory

Explanation:

The statement "the characteristics of living things change over time" refers to the concept of biological evolution, which is widely accepted as a scientific theory in the field of biology. In scientific terms, a theory is a well-substantiated explanation of a natural phenomenon that is supported by extensive evidence, experimentation, and scientific consensus. The theory of evolution, proposed by Charles Darwin and further developed over time, provides a comprehensive explanation for the diversity and change in the characteristics of living organisms. It is supported by a vast body of evidence from various scientific disciplines, including genetics, paleontology, comparative anatomy, and molecular biology.

In contrast, scientific laws describe observable patterns or regularities in nature that are often expressed as mathematical equations or principles. Laws, such as Newton's laws of motion or the laws of thermodynamics, describe specific relationships or behaviors in the physical world.

Therefore, the statement about the characteristics of living things changing over time aligns with the theory of evolution, rather than being described by a scientific law.

Respect for cultural diversity is advantageous to customers, stakeholders, and communities and promotes good health outcomes. Cultural respect is also essential for obtaining accuracy in medical research since many factors, including behaviours, language, norms, beliefs, and viewpoints, can affect health communication.

Cultural health beliefs have an impact on how individuals perceive their health and health issues, when and from whom they seek medical attention, and how they react to advice for a change in lifestyle, medical treatments, and treatment compliance.

Answer:

The electron transport chain is a series of electron transporters embedded in the inner mitochondrial membrane that shuttles electrons from NADH and FADH2 to molecular oxygen. In the process, protons are pumped from the mitochondrial matrix to the intermembrane space, and oxygen is reduced to form water.

Explanation:

The electron transport chain is a series of four protein complexes that couple redox reactions, creating an electrochemical gradient that leads to the creation of ATP in a complete system named oxidative phosphorylation. It occurs in mitochondria in both cellular respiration and photosynthesis.8

Answer:

Stomata allow a plant to take in carbon dioxide, which is needed for photosynthesis. They also help to reduce water loss by closing when conditions are hot or dry. Stomata look like tiny mouths which open and close as they assist in transpiration.

Q:

If 98 out of 200 individuals in a population express the recessive phenotype, what percent of the population would be heterozygotes?

A:

0.42 or 42%

The recessive phenotype is the phenotype that is expressed only when the recessive condition is found in both alleles.

The percent of the population that would be heterozygous is 42%

If 98 out of 200 individual express the recessive allele = 98/200 = 0.49. This is the phenotypic frequency of the recessive allele (q²)... q = 0.7 (√0.49)

Since p + q = 1

1 - 0.7 = 0.3 = p

To find the percent of heterozygous...p² + 2pq + q² = 1

Where 2 x 0.3x0.7= 0.42

Therefore, the percent of the population that are heterozygous is 42%
