Describe the three types of mammals. Give examples of each. How is reproduction/offspring different in each?

Answers

Answer 1

Answer:

1) Monotremes are mammals that lay eggs. The only monotremes that are alive  today are the spiny anteater, or echidna, and the platypus. These mammals are really different from other  mammals. Their body temperature is lower than most warm-blooded animals, a  feature that has more in common with reptiles. Their name comes from the fact  that they have only one body opening for both wastes and eggs to pass through.

2)  Marsupial mammals give birth to babies that are not completely developed.  The babies are very tiny. The babies then crawl up the fur on the mother's belly  into a pouch on the outside of the mother's abdomen. The babies drink milk from  the mother and continue to develop inside the pouch. Koalas, kangaroos, wallabies,  and opossums are some of the better-known marsupials.

3)A placental mammal develops inside its mother's body until its body systems  can function on their own. The name of this group comes from the placenta, an  organ in pregnant female mammals that passes materials between the mother and  the developing baby. Food and oxygen, carried by blood, pass from the mother to  the baby through the placenta. Most mammals, including humans, are placental  mammals.

Explanation:

Answer 2
Extant mammals are divided into three subclasses based on reproductive techniques (monotremes, marsupials, and placentals) consisting of 27 orders. Within each order, families are organized by taxonomic relationship and distinguished by their genus and species.May 19, 2019
Example:- Koala. Although a lot of people call these animals koala bears, they are not actually born but instead are a type of marsupial. ...
Red Kangaroo. ...
Tasmanian Devil. ...
Wallabies. ...
Wombats.

Monotremes are mammals that lay eggs. ... These mammals have a pouch where their young grow and develop. Marsupials are hairy, warm blooded, and produce milk. One of the biggest differences between marsupials and placental mammals is that marsupials give birth quite early and rely less on the nourishment of the placenta.

1. What are the optimal conditions needed for this severe weather events?


2. How do you think people who live in the regions where tornados are most common can prepare themselves for such an event?

Answers

Answer:

Severe weather can occur under a variety of situations, but three characteristics are generally needed: a temperature or moisture boundary, moisture, and (in the event of severe, precipitation-based events) instability in the atmosphere.

Every year in the United States, tornadoes do about 400 million dollars in damage and kill about 70 people on average. Extremely high winds tear homes and businesses apart. Winds can also destroy bridges, flip trains, send cars and trucks flying, tear the bark off trees, and suck all the water from a riverbed.

Answers

Answer:

See Explanation

Explanation:

This study examined the atmospheric pollution created by some waste treatment and disposal facilities in the State of Kuwait. Air monitoring was conducted in a municipal wastewater treatment plant, an industrial wastewater treatment plant established in a petroleum refinery, and at a landfill site used for disposal of solid wastes. Such plants were selected as models for waste treatment and disposal facilities in the Arabian Gulf region and elsewhere. Air measurements were made over a period of 6 months and included levels of gaseous emissions as well as concentrations of volatile organic compounds (VOCs). Samples of gas and bioaerosols were collected from ambient air surrounding the treatment facilities. The results obtained from this study have indicated the presence of VOCs and other gaseous pollutants such as methane, ammonia, and hydrogen sulphide in air surrounding the waste treatment and disposal facilities. In some cases the levels exceeded the concentration limits specified by the air quality standards. Offensive odors were also detected. The study revealed that adverse environmental impact of air pollutants is a major concern in the industrial more than in the municipal waste treatment facilities but sitting of municipal waste treatment and disposal facilities nearby the urban areas poses a threat to the public health.

The chemical energy stored in the student was transformed into mechanical energy as he/she used her muscles to throw the ball. How does this action support the Law of Conservation of Energy?

A. Energy was not conserved in this example because the light energy is no longer available.
B. Energy was conserved because the light energy was transformed into various forms in the process.
C. Energy was conserved because different forms of energy were created at various stages in the process.
D. Energy was not conserved because the light energy from the sun was destroyed as the chemical energy was gained through eating.

Answers

Answer:

B. Energy was conserved because the light energy was transformed into various forms in the process.

Explanation:

Law of Conservation of Energy states that energy cannot be created nor destroyed. However, it can transform into other types of energy. B is the only answer that follows the Law of Conservation of Energy.
