Bubonic plague is caused by a bacillus form of bacterium called Yersina pestis. The bacterium found mainly in rodents and their fleas. This bacteria transmitted through the bite of infected fleas and rodents.

In various parts of the world this plague bacterium still exists as reported in 2003 in Africa killing 180 people. The last reported serious outbreak of this plague was in 2006 in Congo, when at least 50 people died. In recent years, the United States, China, India, Vietnam, and Mongolia have confirmed human plague cases.

Good sanitation, rodents and pest control can help in preventing plague outbreaks. Administering of correct antibiotics to the patients can control deaths.

My best explanation is

Some cancer is in blood and tissue and doesn’t form a tumor, such as leukemia. Therefore a usage of “chemotherapy” is needed.

Sorry if this isn’t a good explanation

What sense organs are located on the head and in the mouth of a fetal pig?
Ratling [72]
The sense organs that are located on the head and in the mouth of a fetal pig are the Ears, mouth, eyes, nose, and tongue. The pig, just like humans, experiences sound, sight, taste, smell, heat, cold, pain and also balance. The way it responds to these assists humans in the recognition of health and diseases. For instance pain and the posture will often indicate a specific disease such as a fracture of the vertebrae in the spine.

Can you describe how a researcher might use naturalistic observation, case studies, and survey research to investigate gender di
Sati [7]

Answer:

The specification of the circumstance is characterized underneath in the interpretation category.

Explanation:

  • To continue investigating differences between men and women throughout the aggressive behavior of employees, a research scientist can use observation methods, research papers, or observational studies.
  • The naturalistic observation was being used without people's awareness to classify the actions of persons throughout the natural world. In this, the researcher examines individuals for some violent actions and often examines gender disparities throughout this workplace climate with aggressive behavior.
  • Throughout the case research, the researcher does a throughout-depth study on gender disparities mostly in current workplace violent behavior. Here also, not only would the researcher observe the behavior, and address questions about the gender gaps between the departments.
  • The investigator focuses on collecting information about the number, spread, and interrelationships of gender disparities throughout the large population through survey studies.

Hypothesis:

  • <u>Research hypothesis (H1): </u>There seems to be a correlation among both gender differences but instead aggressive performance in the workplace.
  • <u>Null hypothesis (H0):</u> There seems to be no correlation regarding disparities in gender as well as violent work performance.

Research approach:

Qualitative descriptive research design could be employed throughout the descriptive research. In all of this, more attention is put on gathering knowledge about prevalence as well as the interconnection of gender disparities with occupational violent behavior. In this, this same data will be gathered by face-to-face interviews, questionnaires on genetic factors, and occupational hostile behavior.

Explain how fertilization occurs
alex41 [277]
<span>I'm assuming this in plants.

Brief-ish answer:

"Fertilization in plants occurs when pollen grains are transported from anthers to stigma. When ripe pollen from an anther catches on the stigma of the same kind of flower, each pollen grain sends out a small thread-like tube."

Here's a fuller answer:

"</span>Fertilization occurs after pollination, when pollen grains land on the stigma of a flower of the same species. During this time, a series of events take place leading to the formation of seeds. A pollen grain on the stigma develops a tiny tube that runs down the style of the ovary. The pollen tube contains a male gamete which meets the female gamete in the ovule. Fertilization occurs when the two gametes combine and their chromosomes join. The resulting product is a normal complement of chromosomes, with some from either parent flower. The fertilized ovule forms a seed, which consists of a food reservoir and an embryo that later develops into a new plant. In gymnosperms (conifers) male gametes are enclosed in pollen grains and are transmitted by wind or insects to the female reproductive organs. Fertilization in angiosperms (flowering plants) occurs when insects or other animals transport the pollen to the female reproductive organ (pistil).<span>
</span><span>Fertilization is the fusion of gametes to launch the development of a new individual organism. In animals, the process entails the combination of ovum with a sperm, leading to the development of an embryo. Fertilization in plants occurs when haploid gametes meet to create a diploid zygote, which eventually forms an embryo.</span><span>"
