Old rivers-Have many meandersYoung rivers-Carry large objectsMature rivers-Carry medium-sized objectsWhat are rivers?Rivers are bodies of flowing water that are typically found on the surface of the Earth. They are formed by the accumulation of precipitation, such as rain or snow, in a specific area and flow in a defined channel towards an ocean, a lake, or another river. Rivers can vary greatly in size and length, with some being just a few meters wide and a few kilometers long, while others can be several kilometers wide and thousands of kilometers long.
They are an important resource for humans and other living organisms, providing water for irrigation, drinking, and industrial uses, as well as serving as habitats for a wide variety of plant and animal life. Rivers also shape the land they flow through, eroding and depositing sediment, and creating features such as valleys, deltas and canyons.

In an enzymatic reaction: Select one: a. The enzyme leaves the reaction chemically unchanged b. The least important level of organization for an enzyme is its tertiary structure c. Increasing temperature above the optimal value slows the reaction rate
Answers
Answer:
c. Increasing temperature above the optimal value slows the reaction rate
Explanation:
Enzyme activity is affected by factors, such as temperature, pH, and concentration.
The rate of an enzyme-catalysed reaction increases as the temperature increases. However, increasing the temperature above the optimal value slows the reaction rate because the enzyme becomes denatured and can no longer function.
Thus, the correct option is "C"
c. Increasing temperature above the optimal value slows the reaction rate
How are fossils that contain vestigial organs consistent with common ancestry?

Explanation:
La evidencia de un antepasado común en los seres vivos, que han encontrado durante décadas científicos que trabajan en numerosos campos, demuestra la descendencia común de estos seres, que la vida en la Tierra se desarrolló a partir de un último antepasado universal, que la evolución existe y que puede demostrar los procesos naturales que han dado como resultado la biodiversidad de la vida en la Tierra. Esta evidencia apoya la síntesis evolutiva moderna, la actual teoría científica que explica cómo y por qué cambia la vida a lo largo del tiempo. Los biólogos evolucionistas han documentado evidencias de antepasados comunes realizando predicciones verificables, probando hipótesis y desarrollando teorías que ilustran y describen sus causas.
La comparación de secuencias genéticas de ADN ha revelado que los organismos filogenéticamente próximos tienen un mayor grado de similitud secuencial que los organismos filogenéticamente alejados. Se pueden encontrar más pruebas de la descendencia común en detritus genéticos como los pseudogenes, regiones del ADN ortólogas a un gen en un organismo relacionado, pero que ya no tienen actividad y parecen estar experimentando un proceso continuo de degeneración por acumulación de mutaciones.

If there is an increase in mass, what has happened?
Answers
Answer:
The greater the mass of an object, the less it will accelerate when a given force is applied. For example, doubling the mass of an object results in only half as much acceleration for the same amount of force. Q: Tony has greater mass than the other two boys he is racing (pictured in the opening image).
Explanation:
Answer:
The greater the mass of an object the more it will accelerate! when a given force is applied the mass of the object will change and thats what causes something called speed! Now you will also increase in energy and it will be hard to slow the object down.

Answers
Answer:
Three eukaryotic organelles that are involved in the transport, packaging, and export of a protein synthesized on a bound ribosome in this cell are -
Endoplasmic reticulum Golgi bodiesRibosomesExplanation:
ENDOPLASMIC RETICULUM - The endoplasmic reticulum ( ER) is a broad, dynamic structure that serves many cell functions, including the storage of calcium, protein synthesis and metabolism of lipids. Separate regions, consisting of tubules, sheets and the nuclear envelope, perform the diverse functions of the ER.GOLGI BODIES -: A membrane bound organelle found in most cells is the golgi apparatus. Before secretion, it is responsible for packaging proteins into vesicles and thus plays a key role in the secretory pathway.RIBOSOMES -: The organelles which aid in protein synthesis are ribosomes. For many cell activities, protein is necessary, such as damage repair and other chemical processes.A ribosome is composed of two subunits:
the small ribosomal subunits- these read the mRNA. The large ribosomal subunits - form amino acid polypeptide chains.Hence , the labelled diagram of eukaryotic cell is attached below.
5. What do porifera use their flagella for?
(1 Point)
O swimming
O eating
reproducing
Answers
Answer:
Porifera use their flagella to eating.
Explanation:
Porifera are immobile animals, typical of marine ecosystems, also called sea sponges and characterized by a lack of true tissue.
Coanocytes are one of the main cells of the porifers, and they are endowed with flagella that allow them to mobilize the water with food particles towards the microvilli, structures that trap them to be later absorbed.
The flagella play an important role in the feeding of the porifers, by conducting the food to the structures responsible for its absorption and processing.
The other options are not correct:
Porifera is immobile, so the flagella do not participate in swimming.Flagella do not participate in the reproductive process of marine sponges.How does the property of cohesion make farming possible?
Answers
Answer:
cohesion refers to the attraction of molecules for other molecules of the same kind, and water molecules have strong cohesive forces to make the crops grow faster
Explanation:
Answer:
Cohesion is the forces holding water molecules together. This concept was covered when talking about properties of water and capillary action. You may remember capillary action is like when you have a little bit of water in the bottom of your cup but the water in the straw is a little bit higher than the water in the cup. Because water is polar - meaning it has a somewhat negative end and a somewhat positive end - it is attracted to other water molecules and other substances, such as the straw.
Cohesion
Now, you may be asking yourself: what does a straw have to do with xylem? Well, just like the water moving up the straw, water moves up xylem. The movement of water in plants is from the roots up through the shoot and out the leaves. Part of the reason for this movement of water is cohesion. The water molecules within the xylem tend to stick together, which allows them to help pull other water molecules up through the xylem - even against the flow of gravity.
When water is moving through the xylem, it is moving between different vessels or tracheids. It is very important that these elements are tightly held together because if there are air bubbles, the effects of cohesion are diminished. That is, if air bubbles get into the xylem, the water will no longer move up through these tubes. We can relate this idea back to our straw. If you have ever had a straw that has even a tiny hole in it, you know that it is very hard - even with the aid of suction - to get the water through the straw and up to you. This is what happens if air bubbles get into the tubes of the xylem.
So , indirectly cohesion helps in farming through xylem....

Raul wants to study how pot size affects the growth of plants. To do this, he intends to purchase three different pots of varying diameter. Then, he will fill each pot with the same amount of soil and plant different kinds of flowers in each pot. Finally, he will place the pots side by side in a sunny location and water each pot daily with the same amount of water.
Answers
Answer:
No
Explanation:
Based on the exact methodology that Raul is using he will never produce valid results. This is mainly due to the fact that there are too many changing variables in his experiment. In order to produce valid results, the experiment can only have one changing variable (independent variable) at a time, while all of the other variables need to be controlled/constant. This would allow Raul to isolate which change is actually causing the desired effect in the plants. The way that Raul has his experiment set-up he will not be able to pinpoint exactly what variable or aspect is actually causing the growth of the plants.

4. a. viral genome is replicated using host cell's machinery
5. d. new viruses are assembled within host cell
6. e. the cell ruptures and releases new viruses to infect new cells
Explanation:
First, the virus attaches to the cell. Then it penetrates the cell membrane and inserts its genome inside the cell. The virus relies on the cell machinery to synthesize its proteins, and also to replicate its genome.
With these components being synthesized and replicated, new viral particles are assembled inside the host cell. Eventually, the cell ruptures, and the newly assembled viruses are released and able to attach to new cells to repeat the cycle
