Answer:

False

Explanation:

Most scientists were not yet concerned about global warming. This was because the major issue during the period between 1940 and 1970 was global cooling with little or no attention on global warming.

However things started to change due to more pollution as a result of technological advances. Global warming started becoming a concern between 1970s and 1990s because of the increase in steady surface temperature.

Afina-wow [57]
The answer is b. hypothalamus.

Hypothalamus is a ventral part of diencephalon. It has many functions including control of hunger, thirst, body temperature, sleep, parenting behaviors, and circadian rhythms.
When an <span>animal </span>is not hungry, and it needs for food are satisfied, is called satiety. There is satiety center responsible for hunger. The center is located in hypothalamus.

The response of plants to environmental stimuli such as light and gravity are called
Jlenok [28]
Tropism

It is a biological phenomenon, indicating growth or turning movement of a biological organism. This is usually a plant in response to the environmental stimulus. This response is dependent on the direction of the stimulus. The stimulus must be perceived first, followed by movement towards or away to the stimulus. There are various types of tropism which are chemotropism, exotropism, geotropism and electrotropism.

Phosphorus (P) is the element with the atomic number 15. Which of the
viva [34]

Explanation:

   Isotopes:

                          ₁₅³¹P   and     ₁₅³²P

     Given parameters:

       ₁₅³¹P                                                   ₁₅³²P          

   Mass number = 31                                    32

   Atomic number = 15                                 15

The two atoms are isotopes. Now let us derive numbers of their subatomic particles

                       ₁₅³¹P                                             ₁₅³²P  

Protons              15                                                 15

Electrons           15                                                  15

Neutrons         (31-15) = 16                               (32-15) = 17

Because they are isotopes, they differ in the number of neutrons alone.

Isotopy is the existence of two or more atoms of the same element having the same atomic number but different mass numbers due to the differences  in the number of their neutrons.

We clearly see that the mass number and number of neutrons pertaining to the atom differs. This makes them isotopes.

Plasmodial slime molds move by A. whipping their flagella. B. streaming along as a mass of cytoplasm. C. infecting a host organi
kow [346]

Answer: streaming along as a mass of cytoplasm.

Explanation:

Plasmodial slime molds are single cells that are fuse together by 1000 nuclei that are formed by the fusion of several flagellate cells. They form fruiting bodies when there is stimulus. The fruiting bodies help to disperse individual cells when there is favorable condition. They move by ooze to obtain good.
