Answer 2

The lithium Atom contains three protons, three electrons, and four neutrons. Lithium Ion has three protons, two electrons, and four neutrons.

What is the difference between an atom and an ion?

The lithium atom is a group 1 atom. It belongs to s group. The name lithium was derived from lithos meaning a stone. Lithium cation is a monovalent cation.

Atom is the smallest unit of matter. It is indivisible and consists of neutrons, protons, and electrons. Atoms, where electrons and protons are not equal, are called ions. Ions can be positively charged or negatively charged. Atoms are unstable while Ions are stable.

Lithium is a group one element. The atomic number of lithium is three. It contains one electron in the outermost shell. When a lithium atom loses one electron from the outermost shell it becomes lithium cation.

The water vascular system of echinoderms _____. The water vascular system of echinoderms _____. is analogous to the gastrovascular cavity of flatworms moves water through the animal's body during suspension feeding functions in locomotion and feeding functions as a circulatory system that distributes nutrients to body cells is bilateral in organization, even though the adult animal is not bilaterally symmetrical

Answers

Answer:

The water vascular system of echinoderms functions in locomotion and feeding.

Explanation:

Echinoderms have a unique vascular aquatic system called the ambulacral system.

The ambulacral system refers to a net of fluid-filled channels derived from the coelom with functions related to gas exchange, feeding, stimuli reception, and locomotion. This system acts as a hydro motor apparatus.

The opening to the exterior of this vascular system is through an opening known as madreporite. This structure is united to the circular channel that surrounds the animal´s mouth and from where five radial channels emerge and extend along each arm. Water runs through these structures and makes it possible the gas exchange, feeding, locomotion, and other functions. By hydrostatic pressure, little tubular feet are protruded and retracted and help the animal to move.

Which of the following organisms breaks down dead material and returns the substances to the environment?

Answers

Answer:

C.Bacteria

Explanation:

The organism that breaks down dead materials are decomposers, ofc lion and vulture arent decomposers. Algae also a producer and not a decomposer. So the only answer is bacteria, bacteria is a small organism that eat and decompose dead things :)

The organism that breaks down dead material and returns the substances to the environment is BACTERIA, which is option C.

BACTERIA especially those that lives in soil are saprophytic in nature. This means that they feed on dead decaying organisms and their excreta (wastes such as urine and faeces) and bring about their decay or decomposition. This occurs through the following'

• they secrete enzymes onto their food source such as a decaying leaf,

• these enzymes break down complex compounds like carbohydrates and proteins into simple inorganic compounds.

• a lot of chemical energy is lost as unusable heat energy.

• the decomposers (bacteria) only absorb a small amount of nutrients and energy for their use

• the rest is then released into the soil, air and water.

Therefore, the organism that breaks down dead material and returns the substances to the environment is BACTERIA.

Explain Give two examples of how abiotic factors are influenced by biotic factors?

Answers

Answer: If this doesn't help just let me know

The abiotic factors will define which organisms are able or not to live in a specified place. The living organisms will constitute the biotic factors, which define if and how can an organism live in a specified environment. So, the abiotic factors are controlling the biotic factors of an environment.

The interaction between humans and water and plants and soil are examples of the influence of biotic factors on abiotic ones.

Biotic and abiotic factors are biological terms to refer to:

Abiotic factors: are the set of non-living physical and chemical components of an ecosystem.Biotic factors: are the set of living components of an ecosystem.

According to the above, living beings (biotic factors) can affect abiotic factors such as water because they contaminate it with chemicals or waste.

Also, plants (biotic factors) see the soil (abiotic factors) because they provide them with nutrients.

A sample of an unknown liquid has a volume of 24.0 mL and a mass of 6 g. What is its density?

Answers

Answer:

0.25 g/cm³ or 0.25 g/mL

Explanation:

Density = Mass / Volume, so you would then plug in your two variables.

D = 6 g/ 24 mL = 0.25 g/mL or 0.25 g/cm³

Answer:

15.607 lbs or 250 g/L

Explanation:

Density is calculated by dividing the mass (6 g.) by the volume (24 mL). With that knowledge you come to the answer which is 250 g/L which is the measurement I'm assuming you'd need considering you're dealing with a liquid.

If you need a different measurement of density, let me know.

(08) as concentrações de soluto dentro e fora da célula sejam diferentes
(16) haja energia na célula para que o transporte de água ocorra
(32) haja lipídios atravessando a barreira
(64) haja parede celular para o rompimento da célula

Answers

Answer:

(08) and (32)

Explanation:

To make osmosis happen there has to be a difference in the concentration of solutes, between the inside and the outside of the cell. To valance this difference in concentration, water has to flow towards a place that has a higher number of solutes.

The lipids in the cell's wall make this membrane semipermeable. This allows the passage of specific components only, such as water through aquaporins. Lipids and other elements are of importance in the barrier because they maintain the cell separated from the outside, allowing it to be balanced as regards the different substances that can interact with it.
