Answer:
Sandstone experiences intense heat and pressure.
Explanation:
For the sandstone to transform into metamorphic rock, it needs to experience intense heat and pressure.
Metaphorical rocks are the type of rock that arises from the transformation of other rocks and elements. For them to be formed, it is necessary that several physical-chemical processes occur that involve high values of temperature, humidity and pressure. For this reason, we can say that when the sandstone turns into these rocks, it is because it is being subjected to these factors in an intense and extreme way.
Answer:
High heat and pressure cause the rocks to become metamorphic. presses and presses down onto the rock, making it stay and compress down
Answer:
Death of macrophages
Explanation:
b. False
b. Crude oil
c. Natural gas
d. Nuclear energy
Nuclear energy is not considered as a fossil fuel. Thus, option D is current.
Nuclear energy is not considered a fossil fuel. Fossil fuels are formed from the remains of ancient plants and animals that were buried and subjected to high pressure and temperature over millions of years. Coal, crude oil, and natural gas are examples of fossil fuels.
On the other hand, nuclear energy is generated through the process of nuclear fission, where the nucleus of an atom is split, releasing a large amount of energy. It is not derived from organic matter and does not involve the burning of fossil fuels. Instead, it relies on the utilization of radioactive materials, such as uranium or plutonium, to produce heat and generate electricity.

Answer:
13L:11D
Explanation:
Based on the photoperiod there are two types of plants -
a) Short day plant
b) Long day plant
Here the term short and long day do not mean that the provided length of day are the critical length of day required for reproduction. But opposite to that it means that the length of the day required for reproduction must be
a) Shorter than the defined length of day for short day plant
b) And longer than the defined length of day for long day plant
Chrysanthemums is a short day plant and thus option 1 with 13L:11D will produce fully developed flower buds
Option A is correct 13L:11D
The researcher's findings illustrate that photoperiod greatly affects the development of chrysanthemum buds, with longer periods of light exposure reducing bud formation. The mechanism behind this is likely due to photoperiodism, a biological response that allows plants to regulate their growth based on day length.
The researcher's findings suggest that the photoperiod, or duration of light exposure, significantly impacts the development of flower buds in chrysanthemums. In the experiment, chrysanthemums with a 13L:11D photoperiod produced fully developed flower buds. In contrast, the plants with a 14L:10D photoperiod produced only partly developed buds and those with a 15L:9D photoperiod did not develop any buds. It is evident from these results that there is a decrease in bud formation with an increase in light hours. Chrysanthemums, therefore, seem to need a specific balance of light and darkness for optimal flower bud development.
The mechanism behind this is likely related to photoperiodism, a biological response to the timing and duration of day and night that controls flowering and other growth in plants. Plants use the phytochrome system to sense changes in day length, which is an essential indicator of season. This system allows them to regulate their physiological activities, such as flowering, accordingly. So, the results of this study underline the importance of photoperiodism in flowering plants.

B) muscles should shiver with less force as the body becomes colder
C) the greater the size of a muscle, the more heat it produces
D) the smaller the size of a muscle, the more heat it produces
Answer:
B
Explanation:
Muscles are predicted to shiver with greater force as the body becomes colder, as a response initiated by the brain's heat-gain center to generate heat and maintain body temperature.
Based on the data provided regarding shivering as a mechanism of thermoregulation, the best prediction is that muscles will shiver with greater force as the body becomes colder. This is because as the temperature drops, the brain's heat-gain center is activated, leading to an increase in random signals to skeletal muscles causing them to contract. Shivering involves these muscle contractions that generate heat to raise the body temperature and prevent the body from losing too much heat.
