Attractions between particles hold the particles of liquids and solids close together.
Why is the attraction that particles have for each other not enough to keep gas
particles close together?
Answer:
Kinetic energy is needed to overcome the force of attraction between particles of the same substance. In solids, particles don't have enough kinetic energy to overcome the force of attraction between them. The particles are packed closely together and cannot move around

When the viral DNA becomes active in the lysogenic cycle, which life cycle does it enter?
A.lytic
B.lysogenic
C.cell cycle
D.DNA replication
Answer:
A.lytic
Explanation:
Lysogenic and lytic cycles are two cycles of viral reproduction. In the lysogenic cycle, the viral DNA is incorporated into the host cell genome. Then, it can be passed on to the cell's daughter cells after it divides.
The other cycle of viral reproduction is called the lytic cycle. In the lytic cycle, the DNA is activated (transcribed). Viral particles can then assemble and replicate, and lyzing the host cell.

If a limiting nutrient is supplied to the producer in the diagram above, what effect could it have on the birds?
Answer: The producers are the bluegrass. Adding a limiting nutrient to the grass would increase the amount of primary productivity. The result would be an increased amount of biomass at the producer level, and increasing biomass and available energy at each successive level. The number of birds could increase, because there would be more for them to eat.

Identifying Parts of a Chemical Equation
A green box contains a blue box and a pink box. The blue box contains C H subscript 4 + 2 O subscript 2. An arrow then leads in the green box to the pink box, which says C O subscript 2 + 2 H subscript 2 O. Lines lead from labels to parts of the boxes. Label A leads to the beginning of the green box. Label B leads to the + in the blue box. Label C leads to the arrow. Label D leads to the 2 in 2 H subscript 2 O. Label E leads to the end of the pink box.

What is the chemical reaction of the burning of methane and oxygen?Exothermic combustion, which releases energy, occurs when methane or octane is burned. CH4 + 2 O2 → CO2 + 2 H2O + energy. The products' energies are lower than the reactants' energies.
A fuel (the reductant) and an oxidant, typically atmospheric oxygen, undergo a high-temperature exothermic redox chemical reaction that results in oxidized, frequently gaseous products and a mixture known as smoke.
Therefore, the given question E (the purple box) suggests the products of the equation of burning methane and oxygen.

The following are sources of Earth's internal heat energy EXCEPT
a. Decay of radioactive isotopes
b. Primordial heat
c. pressure from overlying layers
d. Sun’s energy
The sun's energy is not a source of Earth's internal heat. So the correct option is D.
What is the earth's internal heat?
Nobody has even gotten close to directly examining the interior of the Earth. So there is disagreement among geophysicists as to how heated the Earth's core is. However, the speed at which earthquake waves, sometimes known as "seismic waves," move may reveal a lot to scientists about the composition of the Earth.
The solidity, liquidity, or partial solidity of these materials can also be determined using seismic data. Laboratory results, meanwhile, show what pressures and temperatures the materials inside the Earth should melt at.
The temperature of the Earth's core is thought to be between 5,000 and 7,000 degrees Celsius based on this information. That is far colder than the sun's inside, yet roughly as heated as the sun's surface.
Although the amount of heat created inside the Earth is immense, the amount of heat energy received from the sun is around 5,000 times stronger. The weather is influenced by the sun's heat, which ultimately leads to erosion. It is so paradoxical that although the heat of the Earth creates mountains, the energy of the sun gradually breaks them down again.
Therefore the correct option is D.

What specialized structures in flowering plants increase the probability of
successful reproduction?
Answer:
There a few structures that can increase the chances of successful reproduction; 1) Brightly colored flowers that attract butterflies, bees, and hummingbirds which are pollinators, 2) Fragrant odors emitted from said flowers, and 3) Nectar that is consumed by pollinators.
The flowers are a source of food and nectar on which the bees feed on these bees tend to pollinate and help in the germination of new flowers as they are agents of pollination
Except that winds are also responsible for the successful reproduction. The factors that determines the successful reproduction is based on the color of the flowers. Such as more bight and vibrant flowers favors more reproduction. These flowers attract insects, butterflies, and birds.Hence the bright flowers are the answer.

A person has a high fever of 105°F. State one effect that this high fever would likely have
on enzyme activity.
Answer:
The enzyme will change shape/denature, and stop activity
Explanation:
A person has a high fever of 105F. an effect that such a high fever would likely have on enzymatic activity is denaturing enzymes in the nervous system, possibly causing epileptic seizures.
What is the reason of high fever ?High fever (above 100F) is very dangerous for humans and can be fatal. One of the causes of this problem is the fact that high temperature modifies enzymes in the central nervous system which inducing the modification of the amino acid sequence of the enzymes.
With this given information, it is concluded that a person has a high fever of 105F. an effect that such a high fever would likely have on enzymatic activity is denaturing enzymes in the nervous system, possibly causing epileptic seizures.
