This invention was a commercial failure. Edison resolved that in the future he would only invent things that he was certain the public would want. ... This gave Edison the money he needed to set up his first small laboratory and manufacturing facility in Newark, New Jersey in 1871.

please give 2-3 examples (for each one) of producers, primary consumers, secondary consumers, tertiary consumers, and quaternary
Elis [28]
Producers:

One example of producers found in food chains include plants. They use photosynthesis to make their own food. Examples of plants include trees, grass, moss, flowers, and weeds, to name a few.

Primary consumers are herbivores, feeding on plants. Caterpillars, insects, grasshoppers, termites and hummingbirds are all examples of primary consumers because they only eat autotrophs (plants).

Types of Secondary Consumers
Spiders, snakes, and seals are all examples of carnivorous secondary consumers. Omnivores are the other type of secondary consumer. They eat both plant and animal materials for energy. Bears and skunks are examples of omnivorous secondary consumers that both hunt prey and eat plants.


In the real world, a tertiary consumer can eat many different animals and even plants sometimes. This means that they can actually be carnivorous or omnivorous. Some examples of tertiary consumers include, birds of prey, big cats, and foxes.

FrozenT [24]

Answer:

False.

Explanation:

Linked genes are the genes that are present on the same chromosome and can undergo the process the recombination. The recombinant progeny are obtained by the crossing of the linked genes.

The recombinant frequency and map distance can be deduced by the mapping of the linked genes. The genotype of the heterozygote cannot be deduced by examining phenotype and sometimes the recombinant progeny is completely different from the parents as well as from the heterozygotes.

Thus, the correct answer is false.

Which gastrointestinal (gi) change may be found in the client with burn injuries?
Elena L [17]

In case of severe burn injuries, a person experiences a sudden increase in the number of dangerous bacteria in the gastrointestinal tract approximately 32%. The increase in the dangerous bacteria increase the chance of developing gastrointestinal conditions like irritable bowel disease, and other non-related conditions like rheumatoid arthritis and diabetes.  

But in case of less severe burn injuries, the dangerous bacteria accounted for just 0.5% of the bacteria. An imbalance in the bacteria cause long term health consequences, in fact some of the complications could possibly even result in death of a person with severe burn injuries.

a man is twice as old as his son.Five years ago the ratio of their ages was 9:4.Find the sum of their ages​
elena-s [515]

Answer:

75years

Explanation:

Let the Father's age be represented by 2x

Let the Son's age be represented by x

Five years ago;

Man's age will be = 2x - 5

Son's age will be = x - 5

If the ratio of their ages five years ago was 9:4, then;

2x - 5/x-5 = 9/4

4(2x - 5) = 9(x - 5)

8x - 20 = 9x - 45

- Collect like terms

-20 + 45 = 9x - 8x

25 = x

Hence, the son's age = 25 years

If x = 25, the father's age (2x) will be 2 × 25 = 50years

The sum of their ages will be = 25years + 50years = 75years
