Answers

Answer:

Another Brainly Answer

Explanation:

The Amphibian life cycle isn't as simple as it seems. The main Amphibian that has a longer process are called Frogs. Everyone knows frogs, but they are different from most animals such as turtles. The first stage of frogs are when their in eggs of course. These eggs are called "Tadpoles" and look different than most eggs. These eggs are kept in water until they grow. Which brings me to the next stage. When the tadpoles hatch you would start to see something like a baby fish swimming around. That's still the same tadpoles you saw before just hatched. When it comes to this topic most are confused because frogs don't have tails. Well during these stages a tail is used to help them survive in the water and move around. The third stage of these interesting creatures are when they grow legs. That's when they are able to walk on land. They still have their tail of course. It still helps them swim in water. I don't understand much about why they still have a tail if they've grown legs,  but that's for me to find out soon. Eventually they grow more and more and get better with their legs and lose the tail. Well the tail doesn't just magically disappear. It's actually absorbed  by using something called apoptosis. Then it's pretty much and adult frog.

Describe the difference between endotherms and exotherms. Give examples of each. How does each stay warm?

Answers

Answer:

Explanation:

Answer:

Endotherms use internally generated heat to maintain body temperature. Their body temperature tends to stay steady regardless of environment. Ectotherms depend mainly on external heat sources, and their body temperature changes with the temperature of the environment.

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.

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.

As you move to a higher elevation (e.g. in the mountains), the air pressure drops significantly. In turn...



the temperature of water increases and the density goes up as well.


the temperature of water drops and the density of it goes down as well.


the evaporation rate of water increases at all temperatures causing an increase in volume.


the evaporation rate of water decreases at all temperatures causing a decrease in volume.

Answers

Answer:

the temperature of water drops and the density of it goes down as well.

Explanation:

The higher the altitudes, the lower the temperature.

At high altitudes, molecules tend to be more spread out, so the density of the molecules decrease.

Answers

Answer:

D. a mature pollen

Explanation:

Answer:A plant seed is formed from a fertilized egg.  

What is a seed?A seed is an embryonic plant enclosed in a protective outer covering. The formation of seed begins with fertilization, which occurs when the pollen from the male reproductive organ (stamen) fuses with the female reproductive organ (pistil). The fertilized ovule develops into a seed that contains the embryonic plant and a supply of nutrients to support its initial growth until it can begin photosynthesis. The seed coat is the outer covering that protects the embryo from desiccation, disease, and physical damage.

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

Answers

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:

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.
