Where is kudzu native to?
Why was it brought to the US?
How did kudzu grow uncontrollably?
Answer:
Explanation:
Kudzu is a Woody, climbing night vine trees that is native to China, Japan and also Indian. They are invasive trees.
2. It is introduced to United States from Japan during the the Philadelphia Centennial Exposition in 1876. It was introduced to serve as as an ornamental and it is also planted as a forage crop plant. The southern farmers planted kudzudo as to reduce soil erosion.
3. Kudzu is an aggressive plants and grow uncontrollable because it has ability to grow very fast and it can survive in an area, area with low nitrogen thereby outcompeting the native plants.
Severe flooding in an area caused a population of minnows to become split into two separate ponds. Prior to the separation, the
male minnows all had a moderate number of spots
Following the separation, the first pond was filled with larger fish that fed on minnows, so male minnows with fewer spots were
better able to avoid detection by predators. The minnows in the second pond, however, had very few predators, and female
minnows in this pond preferred to mate with males that had the most spots,
After many generations, the two minnow populations evolved into different species and could no longer interbreed.
Fish Species Average # of Spots
Original Species four to six
New Species 1 zero to two
New Species 2 eight to ten
Which of the following best describes why the two minnow populations evolved into separate species?
Answer:
Different selective pressures were acting upon the two populations, leading to an increase in genetic variation and the formation of two new species.
A healthy six-month old Infant was visiting her grandparents in late 2010. Upon returning home, she developed a slight dry cough and runny nose. Her mother thought it was a common cold and chose not to seek medical attention for the baby. By the end of the week, however, she and her husband knew this was not just a cold. Their daughter began to cough with such force that her face turned red, and she began to expectorate thick phlegm. At times, she even vomited. With each day, she became increasingly fatigued as well. Her mother finally brought her to the emergency room when her face turned blue during a bout of violent coughing. The following are the answers the parents provided for the patient history questionnaire:
Question: What have been the patient's symptoms?
Answer: ______________
Question: When did the patient being to exhibit symptoms?
Answer: ______________
Question: Has the patient traveled recently?
Answer: _______________________
Question: Has anyone else in the family traveled recently?
Answer: ________________________
Question: Has the patient experienced any other recent illness?
Answer: ______________________
Question: Is the patient up to date with vaccinations for her age (6 months)?
Answer: ___________________________
Answer: See explanation
Explanation:
1. Question: What have been the patient's symptoms?
The patient's symptoms are slight dry cough and runny nose.
2. Question: When did the patient being to exhibit symptoms?
The patient begin to exhibit symptoms when she returned home after visiting her grandparents in late 2010.
3. Question: Has the patient traveled recently?
Yes. She has. She went to visit her grandparents.
4. Question: Has anyone else in the family traveled recently?
Yes. Her parents.
5. Question: Has the patient experienced any other recent illness?
No. She hasn't. This wasn't stated above.
6. Question: Is the patient up to date with vaccinations for her age (6 months)?
No. She isn't. It was stated that when the child began having a dry cough and running nose, her mother thought that it was a common cold and thereby choose not to seek medical attention for the baby. This is wrong and shows that she isn't up to date with vaccinations. Even if it's a cold, there should be proper medical attention given to her.
In a lake with three trophic levels (non-native fish, zooplankton, algae), an algal bloom occurs when the small population of zooplankton declines due to the predation of the invasive fish. Which of the following describes why zooplankton are the keystone species in this scenario?
Zooplankton are the smallest of all the herbivorous marine mammals in their communities.
The small population of zooplankton have an unequal effect on the marine community.
Marine mammals depend upon the work of zooplankton to convert sunlight into food.
Zooplankton help other populations survive by keeping out other herbivores.
Answer:
The small population of zooplankton have an unequal effect on the marine community.
Explanation:
According to this question, there are three trophic levels of organism in a lake as follows: non-native fish, zooplankton, and algae. However, due to the declination in the number of zooplanktons in the lake as they were fed on by the non-native fish, the algal population increased to form a BLOOM.
This bloom of algal species can be attributed to the lack of zooplanktons, which represented the only herbivorous (plant eaters) organism in that community. Hence, their relatively small population have an unequal effect on the marine community. This means that the small population of zooplanktons caused an imbalance in the community and this is why ZOOPLANKTON is the keystone species in this scenario.

explain why toxic chemicals are classified as Hazard
Answer:
The reason why toxic chemicals are classified as hazard because they can do as much damage as hazard things and can cause a serious of problems to one's health, for something to be hazard it can be flammable, and toxic chemicals are just that.
Anyone know the answer?!
Answer:
Autotrph is also called producer. Uses solar and chemical energy for the process of photosynthesis. They are ingested by Herbivores also called consumers. Plant-eating consumers are called herbivores, plant and meat eating consumers are called Omnivores and only meat eating are called Carnivores. Carcass eating ones are called decomposers and detritus eating are called Hetrotrophs.

Which of the following most correctly represents biomanipulation through the top-down model?
Addition of quaternary consumers, so that tertiary consumers can decrease
Removal of tertiary consumers, so that secondary consumers can increase
Addition of primary producers, so that secondary consumers can increase
Removal of secondary consumers, so that tertiary consumers can increase
Answer:
B. Removal of tertiary consumers, so that secondary consumers can increase.
Explanation:
Removal of tertiary consumers leads to the increase in the population of secondary consumers because tertiary consumers feeds on the secondary consumers. If the population of predators decreases, the population of prey ultimately increases in that ecosystem. Biomanipulation is the change of an ecosystem by adding or removing species, that feeds on other animals such as predators so we can say that removal of tertiary consumers leads to the increase in the population of secondary consumers.

After fertilisation of plants
occurs between the male gamete and the egg cell, the zygote produced undergoes mitosis forming two cells. explain.
Answer:
Zygote, fertilized egg cell that results from the union of a female gamete (egg, or ovum) with a male gamete (sperm). The zygote stage is followed by cleavage when a cell gets subdivided into further smaller cells.
Explanation:
Fertilization is defined as the fusion of the male gamete (sperm) and the female gamete (egg cell) in plants that develops into a zygote. After fertilization, a series of events occurs in the zygote to develop into a seed.

Cuál de los siguientes enunciados describe al tejido muscular liso? A. Es el tejido formado por fibras musculares que tiene movimiento voluntario, lento y forma al corazón. B. Es el tejido formado por adipocitos que tiene movimiento voluntario, rápido y forma órganos internos. C Es el tejido formado por fibras musculares que tiene movimiento involuntario y forma órganos internos. D Es el tejido formado por miosina y activa que tiene movimiento voluntario y forma al corazón, venas y arterias. aiudA
Answer:
C Es el tejido formado por fibras musculares que tiene movimiento involuntario y forma órganos internos
Explanation:
El tejido muscular es un tipo de tejido formado por células contráctiles especializadas llamadas miocitos. El tejido muscular se divide en tres clases diferentes: tejido muscular esquelético, tejido muscular cardíaco y tejido muscular liso. El tejido muscular esquelético es aquel que se mueve de acuerdo a la voluntad del individuo, cuyas células son multinucleadas y poseen una gran cantidad de mitocondrias. El tejido del músculo cardiaco es involuntario y está formado por células uninucleadas (miocardiocitos) las cuales componen las paredes del corazón. Finalmente, el tejido muscular liso también es involuntario y está formado por células uninucleadas con el núcleo en el centro. Las células musculares lisas contienen un citoplasma con haces de filamentos de actina y miosina los cuales están organizados más irregularmente que en fibras musculares estriadas. Este tipo de tejido (músculo liso) se localiza en las paredes de los órganos internos o víseras como, por ejemplo, el tracto gastrointestinal, conductos de glándulas, el sistema urinario, etc., y en los vasos sanguíneos.

If birth rate of a population is high, what would happen to the population overtime?
Answer:
the population would increase
Explanation:
lets say your population is x,
if you keep increasing it,
x+++++,
it gets larger.
(eventually it may run out of resources and decrease in size, and then increase in size, which we know from observing the population of species in the world around us [and by logically assessing what available resources indicate])
