If 575,250 calories of energy are available at the first trophic level, calculate the number of calories available to the 2, 3 and the 4 level
Answer: See explanation
Explanation:
The trophic level of an organism simply refers to the position that is occupied by an organism in a food web. It should be noted that in the next trophic level, only 10% of the energy will be available. Therefore,
1st trophic level = 575,250 calories of energy.
2nd trophic level = 575,250 × 10% = 57525 Calories of energy.
3rd trophic level = 57525 × 10% = 5752.50 Calories of energy
4th trophic level = 5752.50 × 10% = 575.25 Calories of energy

Which best explains what occurred at point X on the curve?
A. The birth rate was equal to the death rate.
B. The death rate was greater than the birth rate.
C.The rate of emigration was equal to the birth rate.
D. The rate of immigration was greater than the death rate.
Answer:
A. The birth rate was equal to the death rate.
Explanation:
The point X is the carrying capacity and this pajae could be ascribed as the plateau stage of population growth, whereby the maximum number of individuals of a particular species which the environment can support has been reached. Hence, giving a long, flat area of the logistic growth curve. At the stage marked x, growth would seize as the population hovers to attain equilibrium with the natality and fatality rate becoming equal, that is birth rate will be equal to the death rate in the population.

What element will a low mass star produce over its entire life?
Explanation:
Over its lifetime, a low mass star consumes its core hydrogen and converts it into helium. The core shrinks and heats up gradually and the star gradually becomes more luminous. Eventually nuclear fusion exhausts all the hydrogen in the star's core

Many snakes and lizards live in the desert, where temperatures are high during the day and cold at night. How does the temperature range affect the size of the snakes and lizards?
A. High daytime temperatures allow them to grow as large as the food supply will allow.
B. Cold nighttime temperatures limit their size, because large ectotherms need a long time to warm up in the sun.
C. High daytime temperatures limit their size, because large endotherms would overheat on very hot days.
D. Cold nighttime temperatures limit their size, because large endotherms would lose too much of their body heat.
Answer:
A. High daytime temperatures allow them to grow as large as the food supply will allow.
Explanation:
Snakes and lizards are cold-blooded animals. This type of animal cannot maintain a constant body temperature and depends on the temperature of the environment to keep warm and keep its organs and metabolism working.
Room temperature is so important to these animals that they even determine the size of their bodies. For these animals, high temperatures allow them to have their metabolism accelerated, so they can grow as much as the availability of food allows. On the other hand, if there is not enough food, or very cold temperatures, they will need to be smaller in size, as the metabolism will be slow.

What is secondary succession
An example of Secondary Succession by stages:
1. An area of growth.
2. A disturbance, such as a fire, starts.
3. The fire destroys the vegetation.
4. The fire leaves behind empty, but not destroyed soil.
5. Grasses and other herbaceous plants grow back first.
6. Small bushes and trees begin to colonize the public area.
7. Fast-growing evergreen trees and bamboo trees develop to their fullest, while shade-tolerant trees develop in the understory.
8. The short-lived and shade-intolerant evergreen trees die as the larger deciduous trees overtop them. The ecosystem is now back to a similar state to where it began. good day
Describe the lysogenic cycle. Write a paragraph. Please don't copy and paste answers. Thank you.
Answer:
The viral DNA is inserted into the DNA of the host during the lysogenic cycle; however, viral genes are not expressed. During each cell division, the prophet is transmitted to daughter cells. The prophet leaves bacterial DNA after some time and passes through the lytic cycle to create more viruses. hope this helps Explanation:

How would you calculate the distance of a paper airplane
Answer: uh Well, Your foot should be at the end of the starting line you prepared earlier. Once you're ready, you can throw your plane. Measure the distance the paper plane traveled (in centimeters or meters) from the starting point with the tape measure. Your lab notebook should include this data in a table. "Plane 1" will take off from this point.

Case Study The Selkirk Rex cat is a breed known for its curly hair. The allele responsible for this curly hair exhibits incomplete dominance. Two copies of the allele yields very curly hair, a slender body, and large ears. One copy of the allele yields a more sturdy body, wavy hair, and smaller ears. Cats with one copy are preferred for professional cat shows. A man from Argentina recently inherited two sister Selkirk Rex cats from a relative and is interested in breeding them to produce more curly-haired cats. One cat carries two copies of the Selkirk allele. The other Selkirk Rex cat carries one Selkirk allele. What genotypes should he seek in mating partners for his cats to produce the most heterozygous kittens possible in the next generation? Note: he doesn't want any kittens that do not have wavy or curly hair. What genotypes should the breeder choose for mates for his Selkirk cats? Choose the beſt answer from the choices below to maximize the number of heterozygous kittens AND maintain the mutation in the population for future breeding. For the SS cat, he should choose Ss. For the Ss cat, he should choose 55. For the SS cat, he should choose ss. For the Ss cat, he should choose Ss. For the SS cat, he should choose 55. For the Ss cat, he should choose Ss. For the SS cat, he should choose ss. For the Ss cat, he should choose SS.
