Explanation:

There are two principal tissue types that make up the veins of plants: The xylem moves water and minerals. This flows from the plant’s roots upwards. The phloem moves food energy around the plant. This flows in whichever direction the plant needs it to flow. These two tissue types make up the vascular bundle of the plant.

Cells of the amine system are able to respond to the presence of invading organisms because they recognize the

Answers

Answer:

Cells of the immune system are able to respond to the presence of invading organisms because they recognize the antibodies present in the invading pathogen

Explanation:

The mechanisms of human immunity can be grouped into two broad categories: the innate or nonspecific immune system, which provides a first and general defense against any element recognized as foreign, and the acquired or specific immune system that recognizes specific threatening agents and generates a response directed against those elements. When foreign substances enter our body (bacteria, viruses, parasites, proteins from other animal or plant species, cells from other organisms - including those of human origin - and a long etcetera, all of which are given the common name of antigens) and are brought into contact with cells that are members of the immune system, the foreign element or antigen is first captured by certain types of cells that are collectively known as antigen-presenting cells. These cells would correspond to the intelligence service and their mission is to take the antigens, introduce them inside, process them and present the antigens on their surface in a fragmentary way to other cells of the immune system. This results in the activation of lymphocytes that specifically recognize the antigen and ends in the development of mechanisms that mediate the physiological function of the response, that is, the elimination of the antigen. Thus, the immune response can be functionally divided into three phases: the antigen recognition phase, the activation phase of the response, and the effector phase.

Explain a wedge and give 3 examples.

Answers

Answer: A wedge is basically an incline plane. Often portable used for many purposes

Explanation: A wedge is a double inclined plane such that the two sloping surfaces taper to form either a sharp edge or a pointed edge. For example, a knife, an axe etc.

In a few cases, the number of inclined planes used can be more than two as well. In such cases, the sloping surfaces generally taper to form either a very sharp or a pointed edge to split or pierce materials. For example, pins, nails etc.

The front end of a boat is shaped like a wedge so that it can easily cut across the flowing water.

The wedge works on the principle of an inclined plane.

El contenedor que tiene fertilizantes crecerá más.

Explicación:

El contenedor que tiene fertilizantes en dosis óptimas crecerá a un ritmo más alto y producirá más vegetación en comparación con otros contenedores que tienen poco o ningún fertilizante porque los fertilizantes tienen los nutrientes que necesitan las plantas en mayor cantidad para su crecimiento y desarrollo. El fertilizante contiene nitrógeno, fósforo, potasa y algunos otros nutrientes que contribuyen al crecimiento y desarrollo del cuerpo de la planta, por lo que podemos concluir de este experimento que el contenedor con nutrientes crecerá más rápido que otros.

One day, at a certain time, a student measured the shadow of a fence and found that it was 2 m long. The next day, she measured the shadow of the same fence at a different time and found that it was 3 m. long. What can you infer about the time of day at which the student measured the shadows? Explain.​

Answers

Answer:

The time of day the second time the student measured the length of the fence shadow was either earlier or later than the first time she measured the shadow.

Explanation:

As the first time the student measured the shadow of the fence gave an answer of 2 meters, the second time gave an answer of 3 meters. For this reason, the shadow is longer in length. This means that the sun is closer to the horizon, yielding a light beam that is closer to the ground.

Moreover, if the sun was directly above the fence post, there would be no shadow. However, because the sun is closer to the horizon, showing that it is earlier or later then the first measurement, the second measurement has a longer shadow.

(_______) stars, however, will last for several billion years, because

Answers

Answer:

Smaller

Explanation:

Life Cycle of a Star

Stars are formed in clouds of gas and dust, known as nebulae. Nuclear reactions at the centre (or core) of stars provides enough energy to make them shine brightly for many years. The exact lifetime of a star depends very much on its size. Very large, massive stars burn their fuel much faster than smaller stars and may only last a few hundred thousand years. Smaller stars, however, will last for several billion years, because they burn their fuel much more slowly.

Answers

Answer:

The second trophic level consists of organisms that eat the producers. These are called primary consumers, or herbivores. Deer, turtles, and many types of birds are herbivores. Secondary consumers eat the herbivores. Tertiary consumers eat the secondary consumers.

Explanation

An animal that eats producers is called herbivore. Therefore, option (D) is correct.

Herbivores eat plant matter such leaves, stems, fruits, and seeds. These organisms get energy and nutrients from producers, the main source of organic matter in ecosystems.

Cows, rabbits, deer, and many insects are herbivores. Herbivores transform plant biomass energy into a form that higher trophic levels can consume, making them vital to ecosystem energy and nutrient cycles. Therefore, option (D) herbivore is the correct option.

Answers

Answer:

Global warming intensifies water cycle

Explanation:

Global warming can dramatically intensify the water cycle because this phenomenon is associated with an increase in temperature, thereby a higher amount of water is evaporated into the air and a higher amount of ice is melted at the poles. Warmer atmospheric air will have a higher amount of water vapor, increasing the frequency and intensity of rainstorms. In consequence, global warming can significantly increase the probability of flooding in coastal communities.
