Answer:
The correct answer is - Option A. The strongest ant in the colony always gets the most mates.
Explanation:
The survival of fittest is the idea that is developed from the theory of evolution proposed by Darwin in his book Origin of Species. This phrase is used to explain the mechanism of natural selection. According to natural selection which is a process the species that adapt the ecological changes in order to survive and reproduce themselves, carry the traits to the next generation.
The ant colony has different classes on the basis of their role and strength. The queen is most strong ant that can produce offspring by mating with most of the mates.

Explanation:
A biologist explored a remote island and discovered a new living organism. After several observations were made of the
organism, the biologist claimed that it was a vascular plant. His notes are listed below.
"I have found a new organism during my explorations. The organism was found low to the ground and is green. Based on
experiments, the organism seems to require sunlight to survive. Small, oval seeds were
found on the organism; they grew
into identical organisms when put in the soil. The organism had sharp spikes around the main body, most likely for
protection. The organism was able to absorb water from the surrounding soil. It was also observed that the organism used
specialized veins to carry water throughout its body. Based on these observations and experiments, I have determined that
this organism is a vascular plant."
Which of the following observations LEAST supports his claim?
A)
The organism is low to the ground.
B)
The organism reproduces with seeds.
The organism requires sunlight.
D)
The organism was able to transport water through specialized veins.
Answer:
The organism requires sunlight.

Explanation:
Fireflies are a group of insects that possess a lantern organ composed of numerous light-producing cells (photocytes) in their abdomens. The light is produced by a chemical reaction involving the light-emitting organic compound luciferin. In each photocyte, luciferin is activated in an ATP-dependent reaction that is catalyzed by the enzyme luciferase. In the presence of oxygen, the activated luciferin emits light as it is converted to oxyluciferin. The flashes of light are controlled by neurons that innervate the lantern organ. Activated neurons stimulate the release of nitric oxide (NO), an inhibitor of the electron transport chain.
Required:
Identify the main source of the ATP used for activating luciferin
Answer:
The main source of the ATP used for activating luciferin are the mitochondria of the Photosite cells.
Explanation:
Fireflies are organisms that emit cold light by the process of bioluminescence. It is a chemical reaction of male individuals to attract the females that also respond by emitting light.
Luciferin is the molecule responsible for light emission. The chemical reaction involves the luciferin molecule, ATP molecule, enzyme luciferase, and oxygen molecule. Luciferin, the responsible molecule for light emission, is transformed into oxyluciferin by the enzyme luciferase. The enzyme consumes oxygen and ATP, which is the principal source of energy in living beings. Finally, a light of about 560 nm is released.
luciferin + ATP + luciferase + O₂ → oxyluciferin + AMP + CO₂+ luciferase + light
Almost the entire amount of energy involved in the reaction turns into luminous energy. ATP used for this light production process comes from the photosite´s mitochondrial electronic chain, responsible for the organism´s energy production.
Photosites are the cells responsible for light production, and many of their mitochondria are placed near the plasmatic membrane to catch oxygen.
Oxygen gets in the organisms through the lantern trachea. During the respiration process, photosites consume oxygen. Mitochondria placed in the cell periphery near the cell membrane catch the oxygen molecules and produce ATP. ATP produced by oxidative phosphorylation is involved in the production of oxyluciferin, turning into AMP.
Posteriorly, the oxyluciferin molecule is recycled back to luciferin. This process shows how chemical energy turns into luminous energy.
ATP comes from the breakdown of glucose in mitochondria of the cell in the process of aerobic respiration.
The main source of ATP that is used for the activation of luciferin comes from the breakdown of glucose molecules in the mitochondria which is also known as powerhouse of the cell. The fireflies or other insects do aerobic respiration which is responsible for the production of ATP molecules in the presence of oxygen.
A chemical reaction that occur inside fireflies enables them to light up through a process called bioluminescence. A glow is emitted when oxygen, calcium, adenosine triphosphate (ATP), and luciferin pigments combines in the presence of the enzyme luciferase so we can conclude that ATP comes from the breakdown of glucose in mitochondria of the cell in the process of aerobic respiration.

What are the parts and functions of the human brain
Answer:
⭐⭐<==================>⭐⭐
☢ the brain which control and co-ordinate the body of the human being.
↪ the brain is broadly divided into three parts.
➊. cerebrum (fore brain)
➋. midbrain.
➌. hindbrain.
------------------------------------
➊. cerebrum; it is the main part of the brain so it is the faculties of learning reasoning memory, personality, intelligency, thoughts, sensation, action and all voluntary movement.
this part of the brain works according to the receptors. they have both areas such a sensory area and motor areas.
➋. midbrain; this brain controls the cerebral reflex moment. such as the visual auditory stimuli.
➌. hindbrain; it consists into 3 parts such as pons, cerebellum and medulla.
★ pons; Pons located lower part of the brain near the pituitary gland, which regulates the respiration.
★ cerebellum; it maintain the balance of the body. it accurate the movement,also control the smooth movement such as walking, dancing, riding a bicycle etc.
★ modulla: it also located the lower part of the brain which controls the involuntary action such as Heartbeat, breathing,blood circulation, blood pressure, coughing,sneezing etc.

((I need to make the punnet square))
how do you make yourself a better friend .
Answer:
Well we all know the way too overused/ cliched phrases like ”Be your self” or “Always be there for you friend when you need it“ Or even “your friend will be there for you no matter what”. Well I don’t think those are key things. Here’s my list that I have ought to keep since middle school.
1) DONT LIE, this is the most common thing in my opinion. Friends tell lies, and you tell lies. Thats not how friendship works. I wouldn’t even white lie on most occasions due to the fact that if a friend comes in with the worst hair cut you have ever seen in your life, they know it themselves its bad, you don’t gotta make it worse by saying it looks great. Follow the laws of rhetoric to make things play out better then a white lie or even the truth (Art of convincing). Adress the situation, then explains the outcomes and side with hem saying whatver but not main points, just common ones and visible ones, then come up with a resolution, (in these cases just tell em don’t worry about it, it’ll all blow away when _______ (thing that happened).
2) Don’t use money to buy friends, seriously don ‘t. They’ll see you as a free bank and things will only go downhill form there.
3) Never steal or hurt your friend in any way.
4) Sure do what both of you guys or more like but sometimes explore other things, discover new ways and stronger ways to bond. Maybe sucking up to go on a roller coaster or even taking a hit for your friend while playing paint ball.

What is the correct series of steps for the movement of energy in an ecosystem?
Answer:
A food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another; the levels in the food chain are producers, primary consumers, higher-level consumers, and finally decomposers.
Explanation:
Answer:
The flow of energy is always unidirectional. The energy passes from primary producers to primary consumers. From the primary consumers, the energy is passed to secondary consumers and then to tertiary consumers. Thus the energy pyramid is always upright.

What happens to energy as it moves up the pyramid?
Energy availability increases.
O Energy availability decreases.
O Energy production outweighs energy consumption.
Energy production and consumption become equal.
Answer:
The amount of energy at each trophic level decreases as it moves through an ecosystem. As little as 10 percent of the energy at any trophic level is transferred to the next level; the rest is lost largely through metabolic processes as heat./ The pyramid of energy shows that the variety and number of species decreases as you move to higher trophic levels. ... This is also assuming that the organisms of the higher trophic level only eat the one organism. To maintain energy levels, higher organisms must eat more food than those at the lower levels.
