Answer:

100%

Explanation:

We are given a red flower plant. This means its homozygous dominant (RR). We are given a white flower plant. This means it is homozygous recessive (rr). Each plant will give its allele. The red one will always give R and the white one will always give r. Heterozygous (Rr) plants have pink flowers. So they will all be pink.

The energy in fossil fuels is derived from the energy stored in plant and animal matter
timofeeve [1]
<span>The energy which we are using in today's world for our needs is fossil fuel, we used to power our home by burning coal and run our vehicle through the oil or fossil fuel, but we should know that it is limited in quantity and cannot use it once it releases energy or burned, it is created by the dead organic materials like trees and animals etc. which slowly buried in the ground as the time goes and after 1000's of years it get pressurised and rise in temperature make that organic material into fossil fuel, so that's how the fossil fuel comes in existence, which we extract from the ground by drilling deep into the ground.</span>

Which pair of terms most accurately describes life history traits for a stable population of wolves? A. semelparous; r -selected
Lera25 [3.4K]

The correct option is (D) iteroparous; K -selected

Iteroparous organisms are the organisms that reproduce multiple times.

<h3>What is Semelparity and Iteroparity?</h3>
  • Semelparity and iteroparity are the two different reproductive strategies available to living beings.
  • Iteroparous species have multiple reproductive cycles throughout their lifetimes, while semelparous species have just one reproductive cycle before they die.
  • Death that occurs after reproduction is part of a bigger strategy in really semelparous animals that also entails maximizing reproduction at the expense of future survival.
  • There will always be some iteroparous individuals who die between their first and second reproductive episodes, but unless they exhibit symptoms of a state of programmed death after reproduction, they are not termed semelparous.

What problems would you expect to observe in an ecosystem without producers? Be sure to answer this question in paragraph form u
Cloud [144]

The producers are the main source of the food production in the ecosystem. The producers are the organism, which convert the energy from the sunlight into the chemical energy. The consumers use this chemical energy for carrying out the metabolic processes in their body.

Without producers, the consumers cannot obtain their energy. Hence, the ecosystem without any producer would not survive.
