The period of development is the time from conception to birth. (Watch your spelling!)
kenny6666 [7]

Answer:

Prenatal period.

Explanation:

Two main types of reproduction that exist in living organisms are sexual reproduction and asexual reproduction. The fusion of the male and female gamete leads to the formation of zygote in case of sexual reproduction.

The prenatal period may be defined as the time development required for the fetal to grow in the womb. The prenatal period starts from the conception and remains till the birth of the child. Three main stages of prenatal period are germinal stage, embryonic stage and fetal stage.

Thus, the answer is prenatal period.

When selecting among multiple possible phylogenetic trees that fit our data, we commonly use the principle of _____, which means
nordsb [41]

a. parsimony; simplest; fewest

When selecting among multiple possible phylogenetic trees that fit our data, we commonly use the principle of <u>parsimony</u>, which means we choose the <u>simplest</u> possible hypothesis. In phylogenetic analysis, that means selecting the tree that represents the <u>fewest</u> evolutionary changes or mutations.

Explanation:

Phylogeny describes the evolutionary history of on organism or group of organisms.  

A phylogenetic tree structure is used to describe the relationship between various organisms which have originated from common ancestors.  

The Principle of Parsimony is best applied while constructing phylogenetic tree.  

This principle emphasizes on simple observations on a phylogeny which requires only few changes or variations which explain for the difference between the phylogenic sequences.  

This tree structure will only have few specific genetic variations or mutations or evolutionary changes which took place through new appearance of a trait or disappearance of an existing trait.

To my esteemed Biology colleagues: 10/15/19 I am National Park Ranger, Imani. I am writing you as my park is in desperate need o
Zanzabum

Answer:

See explanation below.

Explanation:

1. Explain the difference in the roles of producers, consumers, and decomposers in the Everglades.

In the Everglades, producers would be all <u>species of organisms that are autotrophs such as different species of plants</u>. Consumers are categorized into three: primary, secondary and terciary consumers. <em><u>Primary consumers</u></em><u> feed on plants (e.g. insects), </u><em><u>secondary consumers</u></em><u> eat the primary consumers (e.g. mice or rats), while </u><em><u>tertiary consumers</u></em><u> are higher predators that eat the secondary consumers (e.g. racoons)</u>. Finally, decomposers are bacteria, archaeans, fungi, or worms that live in soil which decompose organic matter.

2. Based on your knowledge of how to classify living organisms, in what domain and kingdom do the producers, consumers, and decomposers belong?

In Biology, the three domains are Archaea, Bacteria, and Eukarya; while there are six kingdoms: Archaebacteria, Eubacteria (true bacteria), Protista, Fungi, Plantae, and Animalia.

  • Producers, that is plants, belong to the Domain Eukarya and the Kingdom Plantae.
  • Primary, secondary, and tertiary consumers also belong to the Domain Eukarya and to the Kingdom Animalia as they are all animals and eukaryotes.
  • Decomposers are classified into the three domains: Archaea, Bacteria, and Eukarya. Bacteria belong to the domain Bacteria, archaeans belong to the domain Archaea, and worms and fungi belong to the domain Eukarya. On the other hand, decomposers are classified into Archaebacteria, Eubacteria, Protista (oomycetes), Fungi, and Animalia (worms).

3. How did energy travel in the Everglades BEFORE the alligators were removed?

Aquatic plants (producers) <-- bass <-- bluegill <-- gar <-- alligator

Aquatic plants (producers) <-- zooplankton <-- bass/bluegill <-- wood stork <-- alligator

Plants (producers) <-- cattle <-- alligator

Plants (producers) <-- insects <-- rats <-- racoons <-- alligator

4. How did removing the alligators from the food web change how energy flowed in the Everglades?

Once the alligators were removed from the food web, the populations that were once in decline began to recover because of the lack of predators. Consequently, the lack of alligators led to the uncontrollable growth of racoons, wood stork, and gar, which could also cause an alteration as they consume ecologically and economically important fish species such as the bass and bluegill.

5. How did the problem begin, and what action(s) should Ranger Imani take to solve this issue?

The problem began when the populations of alligator, an apex predator that sits at the top of the food chain, grew at an accelerated pace. This led to the uncontrolled predation of other organisms that are also fundamental to maintain an ecological balance. Therefore, Ranger Imani decided to humanely euthanize the alligators, which were preying upon them. This led to a huge increase in wood stork, gar, and racoon populations.

Alligators should not be completely removed because they help to maintain an ecological balance. Instead, Ranger Imani should work on controlling populations by implementing Wildlife Population Management strategies, such as sustainable fishing, to prevent a certain species population from reaching a high number of individuals in order to keep a healthy ecosystem where all populations are stable because removing all apex predators is not the appropriate strategy as it significantly alters the ecosystem.

Do microorganisms cause asymptomatic infections or disease?
weeeeeb [17]
Microorganisms that are capable of causing disease are called pathogens. Although microorganisms that cause disease often receive the most attention, it is important to note that most microorganisms do not cause disease. In fact, many probably provide some protection against harmful microorganisms because they effectively compete with the harmful organisms for resources, preventing them from growing.
