Answer:
Difference: Survival for the fittest is the survival of species/organisms with genes better suited to the environment and are selected for survival and passed to the next generation while natural selection works by giving species who are better adapted to a given set of environmental conditions an advantage over those that are not as well adapted.
Explanation:
Evolution is the slow/gradual development of human beings from simple life forms into higher forms of life over millions of years ago as stated by Charles Darwin in his book 'The Origin of Species' in 1959. He argues that human beings evolved from simple life forms into higher forms of life through:
1.Mutation - abrupt change in the form of a living organism as dictated by the climate or genetic components of the living thing involved.
2.Natural selection - a process in which the stronger species out compete the weaker ones for resources (Survival for the fittest).
3.Environmental adaptation - follows after the first two, where the surviving species isolate themselves from others as they adapt to the new environment.

What 4 things can affect the way enzymes work? Explain how each thing affects an enzyme
Answer
temperature, ph, concentration and enzyme substrate
Explanation
Enzymes work best within specific temperature and pH ranges, and sub-optimal conditions can cause an enzyme to lose its ability to bind to a substrate. Changing the pH outside of this range will slow enzyme activity.
Enzymes will work best if there is plenty of substrate
Write any two adaptational characteristics of aquatic plants.
Answer:
Three Adaptive features of aquatic plants (hydrophytes) are as follows: a) Underdeveloped conducting tissues (xylem and phloem) are present. b) The plants body covered with waxy substance. c) The stems are long, soft and spongy.
Explanation:
Answer:
Aquatic plants require special adaptations for living submerged in water, or at the water's surface. The most common adaptation is the presence of lightweight internal packing cells, aerenchyma, but floating leaves and finely dissected leaves are also common.

Explain why a spark from a firework will not hurt you as much as a cup of hot tea?
Answer:
It will not unless it contains as much energy as the cup of tea. So a tiny spark may be at 1,000 Celsius but a whole cup of tea at 90 Celsius will deliver far more heat (energy) to the skin as the spark.

Mia and Raphael are discussing the ketogenic diet, also known as Keto, as a way of losing weight. Using the Keto method depends on changing the proportions of nutrient macromolecules that are eaten
daily to adjust energy metabolism. Which group of macromolecules can be affected by Keto eating choices, and is used for long term storage plus happens to be insoluble in water?
O carbohydrates
Ads
O nucleic acids
O proteins
The group of macromolecules that can be affected by Keto's eating choices, and is used for long-term storage, in addition to being insoluble in water, is lipid.
The ketogenic diet consists of significantly reducing the amount of carbohydrates ingested daily and adding more fat to the diet.
After about three weeks of reducing carbohydrates from the diet, the body enters a metabolic state called ketosis, turning stored fat as the body's energy source.
Therefore, the ketogenic diet can bring benefits to the individual, such as accelerated weight loss and prolonged satiety, but it can also be a difficult diet to follow for long periods, as it is more restrictive.
The ideal, then, is always to seek specialized help when you want to achieve some aesthetic or health goal related to weight loss, so that the professional can develop a diet focused on the needs and individualities of each one.

How can carbon can be stored for a short time in the natural cycle?
Answer:
The carbon cycle is nature's way of reusing carbon atoms, which travel from the atmosphere into organisms in the Earth and then back into the atmosphere over and over again. Most carbon is stored in rocks and sediments, while the rest is stored in the ocean, atmosphere, and living organisms.

Answer:
The greenhouse effect increases temperature, putting the natural instinct to hibernate on hold. Mating seasons rely on warming and cooling trends, as well. Even a slight increase in temperature causes animals to mate earlier.

Why is it necessary for there to be variation in population in order for evolution by natural selection to occur?
Answer:
There needs to be variations in population in order for natural selection to occur because the entire point of evolution by natural selection is only the best variations will survive. So if there were no variations then there would be no natural selection because the animal's survival rate would be the same no matter how many times they reproduce because there are no different variations being introduced into the species. However, if there are variations then the animal's survival rate could be impacted because of the variations, for example, white mice would be easier to find for predators on a dark surface, while a darker mice would be harder to find for predators on a dark surface, thus, allowing the darker mice to prevail as they have a higher survival rate and the species will slowly evolve into the darker mice. But, if there were no evolution, in this case, then no matter what happens, the white mice would not be able to evolve into a darker mice because there are no such thing as variation. That is why it is necessary for there to be variation in order for evolution by natural selection to occur.

Hebrews 11:7
Answer:
Faith, according to the Bible, is not blind. More than half of the verses in the book of Hebrews are dedicated to explaining reasons and evidence to accept the new covenant in Jesus Christ. Nor is faith gullible, or senseless. Instead, godly faith is exemplified by trust. That trust is based on what we know of God, relying on Him for the things we do not know. In particular, godly faith looks forward, from an eternal perspective, and produces obedience, even in the face of hardship. God takes what we cannot see, or cannot understand, and uses it to make good on His word. Since faith relies on what we've seen of God, and trusts Him for the future, it becomes the "assurance of things hoped for, the conviction of things not seen" (Hebrews 11:1–3).

1. What is the major source of energy for the brain
Explanation:
glucose
The mammalian brain depends on glucose as its main source of energy. In the adult brain, neurons have the highest energy demand [1], requiring continuous delivery of glucose from blood.
hope its helpful to you #
The major source of energy for the brain is glucose. Metabolism of glucose provides energy to the brain.
What is the brain?The brain is a body part that operates the various functions of the body. It is present in the head of the body. It is divided into two parts, the left brain, and the right brain.
Energy is something that is produced by the metabolism of food. Energy7 is required to carry out all the processes of the body. To walk, run, work, eat, everything requires energy.
The main source of the energy in animals and plants is glucose. The food we eat converts into energy by the process of respiration. The energy is transported into all parts of the body by blood circulation.
Thus, glucose is the major source of energy for the brain.
