How are invertebrates better? PLZ help ASAP

Answers

Answer 1
Answer: Invertebrateany animal that lacks a vertebral column, or backbone, in contrast to the cartilaginous or bony vertebrates. More than 90 percent of all living animal species are invertebrates. Worldwide in distribution, they include animals as diverse as sea stars, sea urchins, earthworms, sponges, jellyfish, lobsters, crabs, insects, spiders, snails, clams, and squid. Invertebrates are especially important as agricultural pests, parasites, or agents for the transmission of parasitic infections to humans and other vertebrates. Invertebrates serve as food for humans and are key elements in food chains that support birds, fish, and many other vertebrate species.Apart from the absence of a vertebral column, invertebrates have little in common. Indeed, they are distributed between more than 35 phyla. In contrast, all vertebrates are contained within a single phylum, the Chordata. (Phylum Chordata also includes the sea squirts and some other invertebrate groups.) Invertebrates are generally soft-bodied animals that lack a rigid internal skeleton for the attachment of muscles but often possess a hard outer skeleton (as in most mollusks, crustaceans, and insects) that serves, as well, for body protection.

What is a organelle

Answers

An organelle is a functional subunit enclosed by a membrane within a eukaryotic cell. The name "organelle" means little organ and the name comes from the analogy with organs: what an organ is to a body, an organelle is to a cell. So, the organelle is the organ of the cell. There are different types of organelles in cells, such as nucleus, mitochondria, Golgi apparatus, endoplasmic reticulum, chloroplasts, vacuoles, and they all have a different function. For example, the nucleus is the organelle which main function is control of cell activities. Mitochondria are organelles which main function is energy production.

Question 1
Match the description of the different kinds of symbiosis with its type.
Choices are commenalism , mutualism, parasitism

In this type of symbiosis, one organism is helped while the other is harmed.

In this type of symbiosis, both organisms benefit.

In this type of symbiosis, one organism benefits while the other is neither helped nor harmed.



Question 2
Fleas and ticks get their food by sucking the blood of a dog or cat that they are attached to. This can transmit diseases and harm the dog or cat. This is an example of
which type which type of symbiotic relationship?

Question 3
The yucca moth takes pollen from one yucca plant to another plant, which helps pollination and fertilization. While the moth is there, it lays it eggs in the plant. When the eggs turn to larvae, they eat some of the plants seeds, which doesn't harm the plant. This is an example of which type of symbiotic relationship?

Question 4

Question 6
You're on vacation at the shore and get bit by a mosquito at night while walking the boardwalk. The mosquito feeds off of you when it bites you and you are left with a painful, itchy, swollen red mark on your skin. This is an example of which type of symbiotic relationship?

Question 7

This is an example of which type of symbiotic relationship?

Question 8

mutualism

commensalism

Question 9

parasitism

mutualism

commensalism

Question 10
"Good for me, good for you,"is a saying that would describe which type of symbiotic relationship?

parasitism

mutualism

commenalism

Answers

1. 
A) parasitism
B) mutualism
C) commensalism

2. Parasitism 

3. Mutualism

4. Parasitism

5. Commensalism

6. Parasitism

7. Mutualism

8. Parasitism

9. Commensalism

10. Mutualism

Final answer:

The symbiotic relationships are classified as parasitism (one organism benefits while the other is harmed), mutualism (both organisms benefit), and commensalism (one organism benefits while the other is neither helped nor harmed). The examples given illustrate these types of symbiotic relationships in various life forms.

Explanation:

Answer for questions 1-3: The type of symbiosis where one organism is helped while the other is harmed is parasitism. When both organisms benefit it is termed mutualism. When one organism benefits and the other is neither helped nor harmed it is commensalism.

Answer for question 4: Fleas and ticks sucking blood and potentially harming dogs or cats is an example of parasitism.

Answer for question 5: The yucca moth and yucca plant relationship exemplifies mutualism, as the larvae get food and the yucca plant gets pollinated.

Answer for question 6: Athlete's foot fungus thriving on a human causes harm to the host and signifies parasitism.

Answer for question 7: Barnacles living on whales without causing them harm is a case of commensalism.

Answer for question 8: Mosquitoes feeding off humans by biting is another example of parasitism.

Answer for question 9: Birds cleaning alligators' teeth without harm and gaining food is a type of mutualism.

Answer for question 10: When one organism benefits at the expense of another, as in 'Good for you, bad for me,' it reflects parasitism. 'Good for me, doesn't bother you,' aligns with commensalism since one species benefits and the other remains unaffected. 'Good for me, good for you,' typifies mutualism, where both species benefit.
