Answer;
D.Most of the energy from photosynthesis flows out as heat.
Explanation;
-Energy flow is the amount of energy that moves through a food chain. The energy input, or energy that enters the ecosystem, is measured in Joules or calories.
-The largest source of energy for an ecosystem is the sun. Energy that is not used in an ecosystem is eventually lost as heat. Energy and nutrients are passed around through the food chain, when one organism eats another organism.
b. False
Answer: b. False
Many mammals rests for a large proportion of the 24 hour. The rest period usually extent during hibernation. The marine mammals tend to rest or sleep with only one hemisphere is kept at rest. It allows them to keep one eye open this allows them to stay alert against the predators. But the terrestrial or land mammals when take rest both the hemispheres of the brain sleep.
On the basis of the above description, most land mammals have the ability to rest one hemisphere of their brains at a time is false.
In addition to air and water, our body constantly needs regular inflow of food, which provides the energy reserves necessary for movement, breathing, thermoregulation, heart, blood circulation and brain activity. In the process of digestion of food decays to individual glucose molecules which then fall through the intestinal wall into the bloodstream. With blood flow glucose transported to the liver, where it is filtered and delayed in reserve. The pituitary gland supplies the pancreas and thyroid glands signal to the release of hormones that cause the liver to throw out the accumulated glucose in the bloodstream, and then delivers it to the blood to the organs and muscles that are in need of it. Having achieved the desired body glucose molecules penetrate into the cells, where it is converted into a source of energy that is available for use by cells. Thus, the process of continuous energy supply agencies depends on the level of glucose in the blood.
Some viruses uses Lysogenic cycle to insert the viraldna into the host cell dna before it enters a lytic cycle.
The lysogenic cycle also referred to as nonvirulent infection, includes the virus integrating its genome with the genome of the host cell in order to replicate without destroying the host. An example is the structure of a bacteriophage. To reproduce, the phage should first penetrate the host cell.
The lysogenic cycle is characterized by The phage infecting a bacterium and inserting its DNA into its chromosome, enabling the phage DNA (now known as a prophage) to be replicated and transferred on alongside the cell's own DNA.
The lytic cycle includes virus reproduction by utilizing a host cell to produce more viruses, which then ruptured out of the cell. The viral genome is incorporated into the host cell genome during the lysogenic cycle, infecting it from within.

hunt insects in flight
b.
locate flowering plants
c.
find warm places for hibernation
d.
all of the above
The correct answer is option D
Echolocation can be defined as the technique by which the bats use sound to locate the places or objects. It is the active use of sonar to locate the insects for hunting in flight during the night time.
Bats also use this technique to locate the places needed for hibernation during the time they are not active and also for locating the flowering plants.
