Worms are invertebrates. There are actually several phyla of worms. They can live in a range of diverse environments. Some worms live in water, others on land, and some are parasites that live in the digestive systems of other animals! All worms lack legs. Flatworms are the simplest type of worm and have few organs, a head and a tail. Roundworms are slightly more complex than flatworms. They have simple digestive and nervous systems. Segmented worms are the most complex and include earthworms and fireworms. They have circulatory, nervous and digestive systems.

Ragworms are a species of segmented worm. Ragworms (what?)

a. only live on land.
b. have a backbone.
c. lack digestive systems.
d. have circulatory systems.

Answers

Answer 1
The answer is D
This is because in the first sentence it says invertebrates which means no backbone. It says that they can live in water, and says they DO have minor digestive systems. To quote"They have circulatory, nervous and digestive systems." So the answer is D

Two other teachers in my daycare center and I have the children play outdoors at the same time. The playground is VERY crowded, and the children seem to be pushing, screaming and snatching one another's toys. What can we do to stop all of this?

Answers

The first thing I would do is try organize a game possibly. A game where each round kids who win said game, get to play with toys on one side of the area, while the other kids get to sing songs, tell jokes, etc. (if they are allowed to do this)

Maybe you could create a song.
This song would remind kids to not touch each other and to not take things out of others hands.

I am unsure of the age group so my answers may not be great depending on the age, but I’m assuming they are toddlers.

Another solution is buying more toys? Although that could get pricey depending on how many kids there are. Maybe you could also have “shifts” where one group of kids goes outside and another goes in. When the group that was outside comes in, you switch. (If that makes sense.)
The kids inside could read, or sing, etc.

A channel of communication is
a way to relay information using body language.
a verbal cue.
a way that messages are relayed,
a way to achieve effective communication,

Answers

Answer:

A channel of communication is a way that messages are relayed.

Explanation:

Communication channels are the means used to convey a message, facilitating the communication process.

In the communication process, an emitter uses the most appropriate communication channel to transmit a message to the receiver.  This channel is a support, and is the tool used to transmit this messages.

Examples:

If the communication is verbal, the channel is the air through which the sound waves are transmitted. If the communication is written, the channel would be the paper.

The telephone, internet, written press, television and radio are other examples of communication channels.

The other options are not correct because:

One way of transmitting information using body language is limited to visual communication. A verbal signal corresponds to verbal language only. One way to achieve effective communication refers to the quality of the message, which must be clear and understandable.

Answer:

a way that messages are relayed

What are the hidden sides of animal agriculture?

Answers

Explanation:

Meat consumption has grown sharply along with the rising prosperity of developing countries. As a result of this, large-scale livestock farming is now widespread throughout the region. However, an increasing number of people are becoming concerned with the conditions the animals are raised and how they are being treated.

The ideal form of animal farming is free-range, where the animals are allowed to live their lives to the fullest in the best conditions before slaughter. Nevertheless, with the ever increasing demand for meat, free–range farming is not an option for most farmers as this method requires open pastures and more land space. Therefore farmers opt for factory farming where animals are kept in cramped spaces with no room for movement — chickens cannot even stand or spread their wings, continue to lay in their own faeces and urine, are not exposed to outdoor air or sunlight, are cruelly handled, injected with hormones and antibiotics and short lifespan as they are slaughtered as soon as they are ready for the market. Furthermore, they have the potential of exposure to various viruses and bacteria via the manure and urine in their environment.

Such conditions severely affect the physiological and psychological state of the animals being farmed. Physically, animals are prevented from displaying their natural behaviour such as walking, stretching their limbs, dust-bathing and other natural behaviours. Psychologically, animals in factory farms are frustrated, bored and distresses as is shown by their repetitive and /or self-destructive actions. This clearly violates the Prevention of Cruelty to Animals Act 1953 (Revised 2006) which requires animals confined to cages be provided with reasonable space for movement.

Animals confined under such stressful conditions are prone to attack each other, therefore to prevent injuries, chickens are de-beaked, de-horned and tails docked. They are bound to suffer from shock because painkilling medicines are not used in these operations.

Another area of deep concern is the transportation of these farmed animals, which is one of the most stressful activities forced onto them. Animals are crowded into trucks and lorries, and chickens packed tightly into plastic crates, stacked high on top of each other and transported over many miles through extreme weather conditions, typically without food and water.

Animal welfare is an issue that is of increasing significance around the world. Even so, the sad reality is that Malaysia is still far behind when it comes to the issue of farm animals because the priority is on commercial profits rather than animal welfare. As expected, animal welfare will not receive the priority it deserves and can never live up to the expectations of NGOs and animal welfare groups.

In other countries changes have taken place. For instance as of January 1, 2012, the European Union (EU) countries has banned the battery hen cages on the basis of unacceptable cruelty. The law allows a 12 year "phase out" out period meant to allow egg farmers time to implement the transition away from battery cages. Most farmers in the participating countries have opted for the enriched cages, with roomier enclosures that allow hens to stretch their wings, roost on an elevated platform and nest in a designated nesting area. Others have barns or other free-range systems, but the law now clearly wants hens to sit on their nests.

In India, the Animal Welfare Board of India and most husbandry departments have advised all state governments and poultry farmers that battery cages should not be used and existing ones to be phased out by 2017.

Cruelty towards animals in farming is but a fraction of the gruesome reality. It is high time the Ministry of Agriculture and Agro-Based Industry look into a Farm Animal Welfare Act conforming to the Prevention of Cruelty to Animals Act with requirements for best practices and continuance for changes in regulations with animal welfare being a strong driver for increased regulation. Change is certainly needed not only for animals but for farmers who need to be able to plan with utmost priority on good animal welfare practices.

How does the nervous system and cardiovascular system interact?This is a question for my semester exam so someone PLEASE ANSWER THIS!!!

Answers

Answer:

The interaction between the nervous and cardiovascular systems is that the brain controls the functions of the heart and circulatory system through the autonomic nervous system and hormones, while the hearth and circulatory system provides blood with oxygen and nutrients to nervous system.

Explanation:

The nervous system (NS) is responsible for controlling and coordinating all organic activity in the body, including the function of the cardiovascular system (CVS). The interaction between the nervous and cardiovascular systems is due to their specific functions.

The brain is the main organ of the NS, receiving all the information from the internal environment and regulating the functions of the organs to maintain homeostasis.                                                                                             Although the activity of the heart is automatic, NS is in charge of regulating the activity of this organ and the circulatory system, through the sympathetic and parasympathetic innervation of the autonomic nervous system. Additionally, the brain can order the release of hormones, such as adrenaline, which influences cardiovascular activity. CVS is in charge of conducting the blood to all the organs of the body. The relationship of this system with NS is clear: providing blood with nutrients and oxygen to all its organs and tissues, removing carbon dioxide and waste products from metabolic activity.

The interaction between NS and CVS is fundamental for the maintenance of life, and they are interdependent systems, since the functions of one allow the normal functioning of the other.
