Answer: one parent, identical
one parent, different
Explanation:
Asexual reproduction involves a single parent parent who undergoes cell division and produces multiple identical offsprings. The asexual reproduction occurs in single celled organisms like yeast, amoeba, bacteria, and others. Sexual reproduction is a process in which two parents are involved which undergoes gamete formation. In sexual reproduction cell division occurs in both parents individually in the germ cells to produce the gametes the egg in female and sperm in male. When the fusion of egg and sperm occurs the organism so produced after development of fusion product that is zygote is different from both parents genetically and morphologically. Sexual reproduction can occur in both single celled (bacteria) and multicellular organisms (angiosperms, humans).

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:

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.
a plant leaf is 0.04mm long. calculate the length of the image after the cell has been magnified 500 times
Length of leaf = 0.04

4-How is cholera transmitted? How does an earthquake promote transmission?
Answer:
1- Which bacteria seem to be most frequently used in the production of food? Lactobacillus.
2- Why might the influenza vaccine be less effective than other vaccines? Becuse of how fast flu viruses mutate.
3- Which diseases of the gastrointestinal tract can be acquired by swimming in a pool or lake? Why are these diseases not likely to be acquired while swimming in the ocean? The diseases og the GI can be acquired in a swimming pool or lake are: giardia, cryptosporidiosis , qtitis externa, legionella and pseudomonas dermatitis. These are not likely to be acquired in the ocean because of the salt.
4-How is cholera transmitted? How does an earthquake promote transmission? Cholera is transmitted by vibrio cholerae O:1 and O:139 , through fecal-oral route or by eating or drinking contaminated food or water. During an earthquake transmission is promoted because of the contaminated water and inadequate sanitation.
Explanation
1- Lactobacillus is the bacteria most frequently used in food industrydustry, where there are many products.
2- Flu viruses are in constant change and mutation. Vaccines are more effective for some types of viruses. The effectiveness vary through the differents types and subtypes.
3- The salt in the ocean dehydrates cells, and affect them by killing them or stopping their growth. There are less bacterias tolerant to salt.

Carbohydrates and proteins are two types of macromolecules that play critical roles in living organisms.
How carbohydrates are made?Carbohydrates are organic molecules made up of carbon, hydrogen, and oxygen atoms. They are primarily used as a source of energy for the body, but they also serve other functions such as structural support, cell signaling, and cell recognition. Some examples of carbohydrates include sugars, starches, and fibers.
Proteins, on the other hand, are organic molecules made up of amino acids. They have a wide range of functions, including structural support, enzyme catalysis, transport, storage, communication, and defense.
One way that carbohydrates and proteins are similar is that they are both macromolecules that are essential to life. They are both made up of smaller building blocks - monomers - that are linked together through chemical bonds to form more complex structures.
One way that carbohydrates and proteins are different is that their functions are distinct. While carbohydrates are primarily used as a source of energy, proteins have a wide range of functions that are critical to the structure and function of the body.
In summary, carbohydrates and proteins are both important macromolecules with distinct functions. Carbohydrates are primarily used as a source of energy, while proteins have a wide range of functions critical to the structure and function of the body. While they share similarities as macromolecules, their functions are distinct and serve different purposes in the body.

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.

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.
What kinds of anthropogenic activities produce acid rain?
1 the use of refrigerants and aerosols
2 burning of fossil and plant fuels that produce carbon dioxide
3 agricultural fertilizers and methane from animal wastes
4 coal and oil power plants and automobiles
Coal and oil power plants and automobiles produce acid rain. Therefore, option D is correct.
What are acid rain and its harmful effects?Acid rain results from a chemical reaction that begins when gases in the atmosphere, such as sulfur dioxide and nitrogen oxides, are released. These molecules can go very high into the atmosphere, where they interact with oxygen, water, and other chemicals to make acid rain, another type of acidic pollution.
Calcium and magnesium, two elements that trees need for optimal health, can be destroyed by acid rain that seeps into the earth. Acid rain also releases aluminum into the soil, which reduces trees' capacity to absorb water.
Thus, coal and oil power plants and automobiles cause acid rain. Therefore, option D is correct.
