Vertebrates are complex animals, but they still share some characteristics with invertebrates. Mia volunteers at her city's aquarium for the summer. She likes observing the invertebrates. Which statement explains the pattern in the body structures of invertebrates, starting with the sponges and ending with echinoderms?
Answer: Their body structure becomes increasingly more complex.
Explanation:
In the classification of living things, all animals belongs to Kingdom Animalia. This is contains two main groups namely:
--> invertebrates and
--> Vertebrates.
The vertebrates are complex animals which are characterized with the presence of a backbone.
The invertebrates are less complex animals with no backbone. The phyla that exists in this group includes: porifera, coelenterata, platyhelminthes, nematodes,annelida, mollusca, arthropoda,echinodermata and many among others.
Their body structure becomes increasingly more complex from the phylum porifera to the phylum echinodermata. The Sponges are simple aquatic invertebrates that have ASYMMETRICAL BODIES (this makes them to lack specialised tissues that could prevent them from moving about). While the echinodermata have RADIALLY SYMMETRICAL body with body parts arranged around a central mouth and anus. They have a unique system of water canals for transport inside the body and numerous tube feet moving about.

Which kind of organism is an autotroph? consumer producer decomposer herbivore
Answer:
Producer
Explanation:
An autotroph is a type of organism that is capable of producing its own food from inorganic substances. The correct answer is "producer."
Describe autotroph.Autotrophs utilize various processes to convert energy into usable forms. The most common and well-known method is photosynthesis, which involves capturing sunlight and using it to convert carbon dioxide and water into glucose (a type of sugar) and oxygen. Plants, algae, and some bacteria are examples of autotrophs that perform photosynthesis.
They are often referred to as producers because they can convert energy from sunlight (or other forms of energy) into organic compounds through processes like photosynthesis or chemosynthesis.
Autotrophs, such as plants, algae, and some bacteria, are able to synthesize their own nutrients and energy sources, typically using sunlight, water, and carbon dioxide. They form the foundation of food chains and provide energy for other organisms in ecosystems.
Therefore, the correct answer is "producer."

How is the egg transferred from the ovary to the uterus?
through muscle contractions
by using special hairs
by producing estrogen
through secretions of glands
Answer:
by using special hairs
Explanation:
When an egg pops out of an ovary, it enters the fallopian tube. Once the egg is in the fallopian tube, tiny hairs in the tube's lining help push it down the narrow passageway toward the uterus.
Answer:
B: By using special hairs.

Explanation:
Amylase becomes denatured at a temperature of 80c. During an experiment to study the effect of varying temperatures on enzyme activity, amylase's reactivity with starch was measured at a body temperature of 37c and then again at an increased temperature of 42c. How would this increase in temperature affect the experiment?
Answer:
The rate of reaction will increase
Explanation:
Temperature is known to affect the rate of the reaction. Generally, chemical reactions depend on thermal activation. It means that an increase in temperature also increases the kinetic energy of the reactants. Increasing the temperature increases the reaction rate due to the increase in the number of molecular collisions between reactant molecules. The speed of a particle is directly related to its kinetic energy and thereby an increase in temperature also results in an increase in the amount of collisions between molecules per unit of time.

Which of the following is an optional part of a technological system?
output
input
feedback
process
Answer:
Feedback
Explanation:
A technological system is a system that consists of components constructed to work together in order to process an input to an output/result. These components or parts that make up a technological system are as follows: input, processing, output and feedback.
- The input is what is taken in by the system.
- The process is the series of occurrences conducted by the internal parts of the system to bring about an output.
- The output is the final result of the system.
- The feedback is how the system should work in comparison to how it is working.
Among all these parts of a technological system, the part that is OPTIONAL i.e the system can function without, is the FEEDBACK.

explain how and why an earthquake occurs in thorough detail. You should also be identifying the four labels below within your explanation. A good answer would be longer than a paragraph (but < 3)
Answer:
An earthquake is what happens when two blocks of the earth suddenly slip past one another. The surface where they slip is called the fault or fault plane. The location below the earth’s surface where the earthquake starts is called the hypocenter, and the location directly above it on the surface of the earth is called the epicenter.
Sometimes an earthquake has foreshocks. These are smaller earthquakes that happen in the same place as the larger earthquake that follows. Scientists can’t tell that an earthquake is a foreshock until the larger earthquake happens. The largest, main earthquake is called the mainshock. Mainshocks always have aftershocks that follow. These are smaller earthquakes that occur afterwards in the same place as the mainshock. Depending on the size of the mainshock, aftershocks can continue for weeks, months, and even years after the mainshock!

It is also called as the fermentation. It is the kind of respiration which helps the cells to breakdown energy in the absence of oxygen.
What is the other type of respiration called as ?It is called as the aerobic respiration which takes place in the presence of oxygen.
Anaerobic that stands for without oxygen.This is the method of the cellular respiration where it does not basically require the oxygen in order to generate the energy. For the smaller animals for breathing , here is no enough oxygen present so that they will need energy for surviving in absence of oxygen.
Anaerobic respiration is the process in which the cells just break down into sugars just to produce out energy in the absence of oxygen. The respiration is called as fermentation. it mainly takes place in yeast cells, bacteria, and muscle cells of animals.

compare the reproductive strategies of a short lived species such as a starfish and a long lived species such as a hippopotamus
Answer:
Starfish reproduce every winter by ejecting there eggs into the water, since they only live on average 35 years they reproduce about 35 times in their lifetime. Only a couple of the eggs will fertilize and turn into a Starfish.
Hippos are the only mammals in Africa that reproduce in water, Hippos reproduce in May and through June. Hippos usually live to around 40 to 50 years, and most hippos through May and June reproduce more than one time.
Explanation:
Hippos strategies of reproducing are better than Starfish.
