Answer:
The properties of this connective tissue are mutable for a short period of time, under neural control, which provides certain mechanical advantages, which include the ability to maintain various postures without muscular effort; that is, it allows Echinoderms to change the consistency of the body, this is useful to escape predators or crawl along the seabed.
Explanation:
Echinoderms comprise the marine organisms known as starfish, sea urchins, sea cucumbers and sea lilies. These present, for the most part, benthic habits and are distributed from intertidal environments to deep bottoms and at different latitudes. They have a mutable collagenous tissue that allows them to change the consistency of the body, that is, they can rapidly change their stiffness and is involved in processes such as fission and autotomy. Some echinoderms quickly switch back and forth between being soft and stiff, which helps crawl along the seabed. Others twist only once from stiff to soft, letting a starfish cut off one of their arms to escape a predator, that is, they can drop an arm when attacked by a predator. When this happens it is called autotomy or autoamputation and the nervous system tells the mutable collagen tissue near the base of the arm to disintegrate. The wound heals and then the arm grows back, a process that can take weeks to months, depending on the species.
Answer:
saves energy
Explanation:
Mutable collagenous tissue is used to lock an Echinoderm into position.

as it moves through the heart from the vena
cava to the aortic valve?
Right side of the Heart
Explanation:
Blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium of the heart. As the atrium contracts, blood flows from your right atrium into your right ventricle through the open tricuspid valve.
Which molecules contain only carbon, hydrogen, and oxygen?
Select all that apply.
carbohydrates
glucose
proteins
O nucleic acids
[tex] \huge \purple{\tt{Answer:}} [/tex]
glucose
The molecule here that contains only carbon, hydrogen, and oxygen is Glucose. So the correct option is B.
What is glucose?Glucose is a monosaccharide or simple sugar. It is a kind of sugar found in honey and fruits. Glucose is the major sugar present in our body.
It is the main source of cellular energy utilized in the process of cellular respiration. Thus, it helps in proper cell functioning and metabolism.
Starch molecules are composed of various monomers of glucose. They are the polysaccharides of glucose. The structural formula for glucose is C₆H₁₂O₆. This means that glucose is only composed of carbon hydrogen and oxygen atoms.
Glucose is a type of Carbohydrate but there are other kinds of carbohydrates that contain elements like nitrogen and sulfur. Proteins and nucleic acids also contain other elements like phosphate, nitrogen, and sulfur.
Thus only glucose is composed of oxygen, carbon, and hydrogen.
Therefore the correct option is B.

Why is biomass a better alternative to oil?
A. Biomass does not release carbon dioxide.
B. Biomass creates radioactive waste.
C. Biomass does not need to be burned.
D. Biomass is a renewable resource.
Answer:
D
Explanation:
Biomass does release CO2 (when burned) because it is organic - contains carbon compounds.
Biomass does not create radioactive waste.
Biomass is renewable because it comes from plants, whereas oil takes millions of years to make, so it is non-renewable.
The correct option is (d) Biomass is a renewable resource.
Because it can be created from sources that are renewable and can be continuously replenished, such as garbage and plants, bioenergy, also known as energy obtained from biomass, is a sustainable substitute for fossil fuels. And cut down on our gasoline supply, compromising our national security.Some of the advantages of biomass energy are:-A constant and accessible renewable energy source is biomass.It has no carbon emissions.It lessens our dependency on fossil fuels.Is more affordable than fossil fuels.The generation of biomass gives manufacturers a new source of income.Fewer trash items in landfills.Learn more about advantages of biomass energy brainly.com/question/11381203

To stop a wound from bleeding, platelets in the blood clump together to form a blood clot. The clot dries into a hard scab to protect the wounded area. Underneath the scab, the blood supplies nutrients and oxygen that help new skin cells form. As the skin regenerates, the wound closes.
Which body systems interact with the integumentary system to close the wound?
A. Circulatory and reproductive
B. Immune and circulatory
C. Reproductive and immune
D. Digestive and endocrine
B. Immune and circulatory systems interact with the integumentary system to close the wound.
What is integumentary system?The integumentary system is the body system that protects the body from damage and disease, and helps regulate body temperature. It includes the skin, hair, nails, and sweat and oil glands.
The skin is the largest organ of the body and serves as a barrier against physical, chemical, and biological agents. Hair and nails provide protection and support, while sweat and oil glands help regulate body temperature and moisturize the skin. Additionally, the integumentary system plays a role in regulating the body's water balance, storing vitamins, and sensing touch and temperature.

expression?
Answer:
Answer: The Environment.
Environmental factors, such as diet, medicines, or exposure to toxins, can change how genes are expressed.
What are factors affecting gene expression?Gene expression is the process through which a gene's information is used to create a functioning gene product, allowing it to produce end products like proteins or non-coding RNA and ultimately have an impact on phenotypes.
Expressivity can be impacted by a number of elements, such as genetic make-up, exposure to dangerous substances, other environmental effects, and age. Penetrance and expressivity both have a range: People who carry the gene may or may not exhibit the trait, and when they do, the trait's expression can take many different forms.

What best explains why there's fewer secondary consumers than producers?
Answer:
because of inefficiency
Explanation:
The organisms that eat the primary consumers are meat eaters (carnivores) and are called the secondary consumers. ... Because of this inefficiency, there is only enough food for a few top level consumers, but there is lots of food for herbivores lower down on the food chain. There are fewer consumers than producers.

Beavers are able to adapt to the changing conditions of all four seasons. Which of the following would threaten the survival of beavers?
A. hot temperature in July
B. freezing rain in
December
C. forest fire in October
D. snow in January
Answer:
C
Explanation:
The question says that beavers are able to adapt to changin questions in each season, so we know that snow in winter, or heat in summer won't bother them. These types of variations in weather are what the beaver is used to. This would eliminate A (July is in summer, so the beavers would expect heat), B (December is in winter, so the beavers would expect freezing conditions), and D (January is in winter, so the beavers expect the snow). That leaves us with C. Fires are not a typical condition for a season- fires aren't expected every fall. Therefore, when there is a fire, beavers will not know what to do. Hope this helps, and feel free to ask me for more clarification!

1. At the freezing point, the particles in an object have no kinetic
energy.
2. On the Celsius temperature scale, there are no negative
numbers.
3. The more particles an object has at a given temperature, the
more thermal energy it has.
4. Object A is much larger than Object B, but both are made of
the same material. If both objects are at the same temperature, the thermal energy
of Object A is the same as the thermal energy of Object B.
5. When heat is absorbed by an object, the speed of the particles
in the object is unchanged.
Answer:
true
Explanation:
False. At the freezing point, the particles in an object have some kinetic energy.
False. On the Celsius temperature scale, there are negative numbers.
True. The more particles an object has at a given temperature, the more thermal energy it has.
False. Object A is much larger than Object B, but both are made of the same material. If both objects are at the same temperature, the thermal energy of Object A is not the same as the thermal energy of Object B.
False. When heat is absorbed by an object, the speed of the particles in the object is changed.
Explanation:
The temperature is defined as the measure of hotness and coldness.It is measured in terms of degrees Celsius, Kelvins, degrees Fahrenheit.There are negative numbers on the Celsius temperature scale and Fahrenheits temperature scale but not on the Kelvin temperature scale.It is a measure of the average kinetic energy of the particles of the object.The hotter the object, the higher will be the kinetic energy of the particles of the object, higher will be the value of temperature. The colder the object, the lower will be the kinetic energy of the particles of the object, lower will be the value of temperature.The object with more mass will have more particles and more will be the kinetic energy associated with the particles.When heat is added to an object to raise its temperature the kinetic energy of the particles increases. As kinetic energy is directly linked with speed or velocity.So from this, we can conclude that :
At the freezing point, the particles in an object have some kinetic energy.
On the Celsius temperature scale, there are negative numbers.
The more particles an object has at a given temperature, the more thermal energy it has.
Object A is much larger than Object B, but both are made of the same material. If both objects are at the same temperature, the thermal energy of Object A is not the same as the thermal energy of Object B.
When heat is absorbed by an object, the speed of the particles in the object is changed.
