The diffusion of a substance into or out of a cell requires

Answers

Answer 1

Answer:

Diffusion is one principle method of movement of substances within cells, as well as the method for essential small molecules to cross the cell membrane. Gas exchange in gills and lungs operates by this process. Carbon dioxide is produced by all cells as a result of cellular metabolic processes.

Explanation:

Answer 2

The diffusion of a substance into or out of a cell requires a process called diffusion, by which the molecules pass out through the plasma membrane.

What is diffusion?

Diffusion is a key mechanism for material transfer within cells and for the passage of critical tiny molecules across the cell membrane. This process controls the exchange of gases in the gills and lungs. All cells release carbon dioxide as a byproduct of biological metabolism.

There are two processes by which the molecules pass through a semi-permeable membrane. The processes are osmosis and diffusion. When the material transfer from low concentration to higher concentration.

Thus, diffusion is the process by which molecules travel through the plasma membrane to allow material to enter or exit a cell.

Answer:

I think it’s B

Explanation:

Veteran trees are home to a variety of invertebrate species because a woodland's diversity is essential (insects, spiders, millipedes, centipedes, etc.), Thus, option B is correct.

What is the rise in biodiversity in woodland ecosystem?

In addition to lichens and fungi. Mature forests also favor bats among other species. Biodiversity in the woodland is a result of structural diversity.

Stability increases with biodiversity in ecosystems, species, and people. For instance, species with numerous populations that are adapted to a wide range of conditions and high genetic diversity are more likely to be able to withstand disturbances, disease, and climate change.

Generally speaking, expanding the variety of habitats or vegetation structures present at a site can be done to increase biodiversity.

II. en el primer contacto adquirió anticuerpos.

III. interviene la inmunidad Adaptativa, la cual presenta "memoria".

IV. su sistema defensivo está preparado frente a una segunda exposición

a. I y II son correctas

b. III y IV son correctas

c. II, III y IV son correctas

d. I, II y III son correctas.

Answers

Respuesta:

La respuesta correcta es la C, ya que II, III y IV son correctas.

Explicación:

Nuestro sistema inmunológico nos defiende de agentes patógenos que pueden enfermarnos, y está compuesto por dos tipos distintos de inmunidades: la inmunidad innata y la inmunidad adaptativa.

La inmunidad innata es aquella que reacciona primero cuando se presenta una amenaza, atacando a los patógenos de manera inespecífica gracias a mecanismos que ya existían antes de que se desarrolle la infección. Cuando se trata de inmunidad innata, nuestras principales barreras de defensa son la piel y las mucosas, y las células de la respuesta inmune de mayor relevancia son los neutrófilos, entre otras.

Por el contrario, la inmunidad adaptativa, es de respuesta tardía y puede actuar de maneras diferentes dependiendo de cuál sea el patógeno invasor. Hay dos tipos de inmunidad adaptativa, la humoral y la celular. De la inmunidad humoral participan principalmente los linfocitos B, que fabrican anticuerpos específicos; mientras que la inmunidad celular es llevada a cabo por linfocitos T. La ventaja que tiene la inmunidad adaptativa en comparación con la innata es que es específica, diversa, más eficaz, y POSEE MEMORIA.

Las células de la inmunidad adaptativa presentan la capacidad de "recordar" cómo el cuerpo actuó ante una amenaza en el pasado para poder llevar a cabo un plan mucho más eficaz. Esta es la razón por la que las vacunas funcionan: porque se le inyecta a los individuos una versión débil del patógeno (por ejemplo, del virus que causa la varicela) para que el cuerpo "aprenda" a vencerlo para cuando se encuentre con ese microorganismo en un futuro.

Answers

I did 80 divided but 5. Which gave me 16 so the speed of the rabbit is 16 mph

Answer:

[tex]\boxed {\tt 16 \ m/s}[/tex]

Explanation:

Speed can be found by dividing distance by time.

[tex]s=\frac{d}{t}[/tex]

The rabbit travels 80 meters in 5 seconds.

The distance is 80 meters and the time is 5 seconds.

[tex]d= 80 \ m \\t- 5 \ s[/tex]

Substitute the values into the formula.

[tex]s=\frac{80 \ m }{5 \ s}[/tex]

Divide.

[tex]s= 16 \ m/s[/tex]

The rabbit's speed is 16 meters per second.

Two differences between hormones and the nervous system

Answers

Answer:

Hormones can be proteins, lipids or cholesterol-based molecules. Neurotransmitters are protein. The main difference between hormones and neurotransmitters is that Hormones are produced in the endocrine glands and released into the bloodstream where they find their movement targets at a distance from their origin. In contrast, Neurotransmitters are released into the synaptic space by a terminal of an excited presynaptic nerve cell and transmit a nerve signal to the neighboring postsynaptic nerve cell.

Explanation:

Answer:

the nervous system and endocrine system (hormones) is that the nervous system uses electrical impulses to send messages through neurons while endocrine glands use hormones to send messages to the target cells through the bloodstream.

Given that almost all organisms obtain energy from food by the process of cellular respiration, which is the most likely explanation for what prevents Earth from running out of oxygen?

Answers

Answer:

Oxygen cycles keeps the flow of oxygen at a constant rate.

Explanation:

The oxygen constitutes about 20% of the gaseous components in the atmosphere and it's being renewed continuously by the various microorganism and primary producers as green plants that use photosynthesis and converts the sunlight and carbon dioxide to water and releases oxygen. Oxygen cycle makes life possible as most of the elements are combined with oxygen in some way or another and are found on the lithosphere, hydrosphere, and atmosphere even biosphere hence its is present insufficient amounts.

Answer:

A.)     The net effects of the reactions of photosynthesis and cellular respiration are the opposite of one another, therefore the products of one are the reactants of the other, creating a cycle.

When carbohydrate consumption exceeds the body's immediate needs for energy, glycogenesis ____________ .

Glycogen storage space in the liver and muscles is limited. When glycogen stores are full, use of glucose for energy ____________ and oxidation of fat for energy ____________ .

Overall, when carbohydrate intake is excessive, lipogenesis ____________


Increase or decrease

Answers

Answer:

When carbohydrate consumption exceeds the body's immediate needs for energy, glycogenesis  decreases.

The process of conversation of stored glycogen in the liver and muscles  to glucose is Glycogenesis. It takes place when the blood glucose drops,below certain levels and the body cells need glucose for biochemical activities.Therefore, when there are excess CHO consumption,more glucose would be in the blood,and thus no need for glycogenesis.(breakdown of glycogen)

Glycogen storage space in the liver and muscles is limited. When glycogen stores are full, use of glucose for energy __Increases__________ and oxidation of fat for energy ___decreases_________ .

Definitely, this is a simple logic.As the storage for glycogen is limited,excess glucose  move into the blood, since they can not be converted to glycogen.The glucose is expended through cellular reduce the amount in the blood. Therefore, Gluconeogenesis, the production of glucose from non-CHO substances drops. Hence beta- oxidation drops.

Overall, when carbohydrate intake is excessive, lipogenesis increases.The process of converting excess CHO to fatty acids.Biochemically it is the process of converting the Carbon precursor of acetyl co -A to fatty acids.Therefore this increases to synthesized more fatty acids from CHO
