Answer:

Whether an allele is dominant or not does not affect how common a trait is. Now of course traits can become more common over time. The changes just don’t have anything to do with whether the trait is dominant or not. If brown eyes gave an advantage, then it would start to become more common.

Explanation:

Traits that provide advantage to the organism become more common over time due to natural selection. Therefore, traits become common due to natural selection.

Due to natural selection, traits that are desirable to an organism and help in its survival in an environment and allow them to reproduce successfully become common over time which help them to acclimatize more successfully.

For example, in a population of birds that feed on insects, some birds have longer beaks while some have shorter beaks. successful at obtaining food and surviving than birds with shorter beaks. Birds having longer beaks will feed on insects more easily than the birds with shorter beaks.

Longer-beaked birds with period of time will become more common in the population as they outcompete other birds for resources. Natural selection is influenced by various factors, such as genetic drift, gene flow, etc.

Therefore, desirable traits that are necessary for population will become more common over time due to natural selection.

Answer:

Kinetic energy of dodgeball = 16 kg-m/s

Explanation:

Given:

Mass of dodgeball = 2 kg

Velocity of dodgeball = 4 m/s

Find:

Kinetic energy of dodgeball

Computation:

Kinetic energy = (1/2)(m)(v²)

Kinetic energy of dodgeball = (1/2)(Mass of dodgeball)(Velocity of dodgeball²)

Kinetic energy of dodgeball = (1/2)(2)(4²)

Kinetic energy of dodgeball = (1/2)(2)(16)

Kinetic energy of dodgeball = (32/2)

Kinetic energy of dodgeball = 16 kg-m/s

Answer:

glucose

Explanation:

The digestive system breaks food down into nutrients such as glucose. Now the circulatory system enters the picture. It transports glucose and other nutrients from the digestive system to the cells. The circulatory system also transports oxygen from the lungs to the cells.

Answer:

Every population experiences genetic drift, but small populations feel its effects more strongly. Genetic drift does not take into account an allele's adaptive value to a population, and it may result in loss of a beneficial allele or fixation (rise to 100% frequency) of a harmful allele in a population.

Sharks keep ocean ecosystems in balance

Sharks limit the abundance of their prey, which then affects the prey of those animals, and so on throughout the food web. Because sharks directly or indirectly affect all levels of the food web, they help to maintain structure in healthy ocean ecosystems. HOPE THIS HELPS!!!!!!!!

Explanation:

Answer:

b. It usually affects the urogenital system but may also affect the eyes.

e. It is gram-negative bacterium.

d. It must be grown on selective and enriched media.

g. It usually affects the nervous system.

f. It can cause asymptomatic infections.

Explanation:

Neisseria gonorrhoeae is a gram negative bacteria known to cause the sexually transmitted infection called Gonorrhea. Gonorrhea is easily treated with antibiotics, as long as the patient seeks early care and discovers the disease early on, as it can be asymptomatic, especially in women. When left untreated, Neisseria gonorrhoeae can infect the nervous system, causing many problems and even leading to death.

Despite being known to attack the urogenital system, this bacteria can attack the eyes generating gonococcal conjunctivitis, which is also sexually transmitted.

Neisseria gonorrhoeae is a fastidious bacteria, which means that it only grows in specific, selective and enriched culture media.

Answer:

It is c.

Explanation:

Most living organisms need to take in oxygen to survive. It is responsible for plants and seaweed.

Some seaweeds are microscopic, such as the phytoplankton that live suspended in the water column and provide the base for most marine food chains. Some are enormous, like the giant kelp that grow in abundant “forests” and tower like underwater redwoods from their roots at the bottom of the sea.

Most are medium-sized, come in colors of red, green, brown, and black, and randomly wash up on beaches and shorelines just about everywhere.

The vernacular “seaweed” is a bona-fide misnomer, because a weed is a plant that spreads so profusely it can harm the habitat where it takes hold.

Therefore, Most living organisms need to take in oxygen to survive. It is responsible for plants and seaweed.

Answer:

1. Base triplets code for a single amino acid

2. Amino acids are linked based on the genetic code.

3. Connecting amino acids form proteins

4. Proteins make up most enzymes which regulate cell processes,​

Explanation:

Genes, which are found in DNA, holds the information needed for every life process in an organism. However, the information in this gene needs to be utilized via a process called GENE EXPRESSION. Gene expression involves two processes namely; transcription and translation.

In transcription, information on DNA is copied into an mRNA strand, which is then used to synthesize an amino acid sequence in the translation process. The amino acids are joined together in a peptide linkage to form PROTEIN, which is responsible for regulating the cellular processes that occur in our cells. In a nutshell, the process is summarized as follows:

- Base triplets code for a single amino acid e.g. AUG codes for methionine

- Amino acids are linked based on the genetic code

- Connecting amino acids form proteins

- Proteins make up most enzymes which regulate cell processes.

Because natural resources cannot be human-made.

Answer:

Plants reform the carbon into climatic carbon dioxide into carbon-containing organic compounds, such as sugars, fats, and proteins. Plants take in carbon dioxide by minute openings into their leaves, called stomata. They connect atmospheric carbon with water and produce organic compounds, utilizing energy trapped from sunlight in a method called photosynthesis. The by-product of photosynthesis is oxygen, which plants discharge into the atmosphere by the stomata.
