Which of the following is true about natural selection? Choose 1 answer:

Answer:

what is the potential difference across electrical load that have risistance of 4 and a current of 3 A following through it

Answer:

Yes

Explanation:

oxygen is taken out of the air photosynthesis, then photosynthesis produces organic molecules that contain oxygen... through respiration and decay of living organisms, oxygen enters the lithosphere

Answer:

One is increase whereas the other is decrease in concentration.

Explanation:

This table shows that concentration of carbondioxide gas in snake's blood is higher in the blood due to respiration process but after breathing, the concentration of carbondioxide gas decreases in the blood while on the other hand, when the carbondioxide gas is lower in the blood, the concentration of oxygen increases due to loading of blood cells with oxygen in the lungs so one is increase whereas the other is decrease in concentration.

Answer:

Charles Darwin's theory of evolution states that evolution happens by natural selection. Individuals in a species show variation in physical characteristics. ... As a consequence those individuals most suited to their environment survive and, given enough time, the species will gradually evolve

Answer:

The procedure is given below.

Explanation:

First we record the data of the pollutants that is releasing from the factory. Record the population of the coral reef which are not affected from these pollutants then take the data again and record the population of coral reef that is affected from the pollutants. If the population of coral reef that is affected from that pollutants increases it means that the pollutants damaged the coral reef population at higher rate. The purpose of this lab is to find out the negative effects of pollutants that is released from the factory on coral reef.

Answer:

There would be two populations of fish:

Light-colored fishes near the surface

Dark-colored fishes near the bottom.

Explanation:

After many generations, there would be two populations of fish: Light-colored fishes near the surface and Dark-colored fishes near the bottom as light-colored fish survive better near the surface and dark-colored fish survive better near the bottom due to the lighting conditions and predators in the new habitat.

Answer:

I = 2.1 A

Explanation:

This is physics, but I will answer here either way.

First, the battery produces a voltage of 12 V in a resistor with 6 ohm, and we want the current flow (I). We need to apply the following expression:

V = R * I   (1)

This is the Ohm's law. From here we can solve for I and:

I = V/R   (2)

Now, we just need to replace the data and solve for the current:

I = 12.6 / 6

Hope this helps

Answer:

Plants convert carbon dioxide and water into sugar and oxygen through the process of photosynthesis. Plants absorb carbon dioxide from the atmosphere during photosynthesis. A small amount of carbon dioxide is released during leaf respiration (intake of oxygen), but it is quickly re-absorbed during photosynthesis.

Answer:

Humoral immunity refers to the component of the adaptive immune response that is caused by B cells, antibodies, and type 2 helper T cells (Th2), as well as circulating mast cells and eosinophils to a lesser extent.

Antibodies is circulated throughout the blood in Humoral immunity.

B cells changed into plasma B cells that is responsible for the production of antibodies against a specific microbe such as bacteria and virus etc. The humoral immune system attacks and controls the antigens that are present outside the infected cells. Humoral immunity is also known as antibody-mediated immunity so it is concluded that antibodies provides immunity in humoral immunity system.

Answer:

Dermal tissue covers and protects the plant, and controls gas exchange and water absorption (in roots). Dermal tissue of the stems and leaves is covered by a waxy cuticle that prevents evaporative water loss.

Answer:

A species' population that is genetically diverse is more likely to adapt and recover from environmental changes. A genetically diverse population is more likely to possess variations of alleles that are suited for the environment and its changes. Those individuals are more likely to survive to produce offspring bearing that allele.

Answer:

The shape of a nerve cell in a nerve cell in an animal is different from the shape of a muscle cell. A nerve cell is long and branched whereas a muscle cell is pointed at both ends and has a spindle shape.

Muscle and nervous tissues rely on electrical activity to function. Muscle tissue generates force to provide movement, and nervous tissue is responsible for transmitting electrical and chemical signals throughout the body. Muscle and nervous tissues are considered excitable tissues.

Nota: Imagen de las rocas en archivo adjunto

Answer:

A- Roca sedimentaria

B- Roca Ignea

Explanation:

A- Características: A simple vista pareciera ser una roca con restos fósiles sedimentados, de colores opacos en los tonos de los marrones. Pareciera ser una roca sedimentaria. Las rocas sedimentarias se forman por acumulación de sedimentos en capas, uno sobre otro, incluyendo dentro de estas capas restos animales o vegetales que quedan incrustrados. Una vez tapados por mas capas, a medida que pasa en tiempo, los restos se van fosilizando y las capas se sedimiento se van solidificando hasta formar una roca.

B- Características: A simple vista se pueden observar distintos colores: rosa, blanco y negro. Entre estos tres, el rosa es el color que predomina. Cada color, correspondiente a un mineral, se observa en forma granular. La textura de este elemento parece ser suave, lo que indica un uso industrial y consecuente importancia económica. Puede tratarse de una roca de granito, de orígen igneo intrusivo. Conformadas principalmente por cuarzo y feldespato, de granos visibles a simple vista. Pueden observarse tambien otros minerales presentes. Por esta composición de minerales, la roca adquiere coloración general rosa, gris o blanca. El cuarzo da color blanco. El feldespato, predominante, puede dar colores claros a rosa salmon en distintas tonalidades. Otros compuestos pueden aportar colores oscuros como el que se oberva en la foto.
