Answer;

-Damage may occur if the tachometer's needle enters the red zone

Explanation;

A tachometer is a sensor device used to measure the rotation speed of an object such as the engine shaft in a car, and is usually restricted to mechanical or electrical instruments.

Tachometer , indicates the engine revolutions per minute. Damage may occur if needle enters red zone. The “redline” on a tachometer indicates that engine speeds above that value are likely to cause damage to the engine, especially if operated continuously at that speed for more than a few seconds.

In pea plants, purple flowers are dominant to white flowers, and the purple and white alleles are represented with P and p, resp
amm1812

Answer: 75% of the plants are purple and 25% are white. The phenotypic ratio can be expressed as 3:1.

Explanation:

Heterozygous means that its genotype has two distinct alleles, i.e. a dominant and a recessive one. So the genotype of the plants is Pp, and each plant has two alleles since<u> they are diploid organisms, which have two copies of each gene. </u>

<u>Each plant produces gametes, which are haploids cells. That is, they only have one copy of each gene (one allele)</u>. So, the gametes produced by Pp have a P or p genotype.  During fertilization, the maternal and paternal gamete are fused to form a diploid zygote where their genotype will have one allele from the father and one from the mother.

By making this monohybrid cross, we cross the gametes of each parent in the punnett square (see picture)

In the offspring, we see one PP genotype (homozygous dominant), two Pp genotypes (heterozygous) and one pp genotype (homozygous recessive). <u>Since we know the P allele is dominant and it codes for purple color, a genotype only needs one P allele to express that phenotype</u>. So Pp and PP organisms are purple, and only pp is white. That means 75% of the plants are purple and 25% are white. The phenotypic ratio can be expressed as 3:1.

A food chain or food web can provide good information including _____. how much energy is transferred from one organism to anoth
Artemon [7]

Answer: A food chain or food web provide information on the eating patterns of organisms, how energy is transfered from one organisms to another and the flow if energy in the ecosystem.

Explanation:

Food chain is the link of network that that starts from producer to the consumer and finally ends at the predator species and decomposer species in the ecosystem. It describe the feeding relationships among organisms.

Food web contains interconnection of several food chains in the ecosystem. It shows several feeding relationships in food chains .

Both food chain and food web provide information of how organisms are interconnected, their eating patterns, how energy is transferred from one organisms to another and flow of energy in the ecosystem.

IgorC [24]

Hurricane Katrina.

It was the year 2005 when Hurricane Katrina marked its destruction in United States. The damaged caused by this was beyond repairable, there’s a reason why Katrina is marked as one of the most destructive hurricanes of all times in the history of U.S.

The impact hurricane Katrina had on aquatic ecosystem was terrifying. 150,000 acres of coastal wetlands was damaged. Approximately fifty sea turtles nests were lost. Oil, chemicals, and various other hazardous waste which released in the aquatic ecosystem resulted in the death of aquatic habitats. These are just a few examples of the impact the disastrous Katrina Hurricane had in our ecosystem.
