Why is evolution classified as a theory?
In the same way that Einstein's theory of gravity is referred to as a theory, scientists also discuss evolution as a theory.
A theory is an explanation for how a natural phenomenon functions that has undergone extensive testing through observations and experiments intended to establish the validity of the explanation. In this context, evolution might be considered both reality and a theory. The fact that creatures have altered or evolved over the course of Earth's history is undeniable. Additionally, scientists have looked into the mechanisms that could account for the main patterns of change in biology. Since it provides a comprehensive account of events that have taken place in the natural world, evolution is referred to as a theory.

Which of the following glands can be observed on the ventral surface of the sheep brain? View Available Hint(s) O Pineal gland O Olfactory bulb O Pituitary gland O Mammillary body
The ventral surface of the sheep brain contains several important glands, such as the pineal gland, the olfactory bulb, the pituitary gland, and the mammillary body.
The pineal gland, also known as the epiphysis cerebri, is a small endocrine gland that is located in the diencephalon, the middle part of the brain. The pineal gland produces the hormone melatonin, which helps to regulate the body's circadian rhythm, or internal clock. Melatonin helps to regulate the sleep-wake cycle, and its production is influenced by the amount of light that the body is exposed to.
The olfactory bulb, also known as the bulbus olfactorius, is a small structure located in the forebrain, the front part of the brain. The olfactory bulb is responsible for the sense of smell, and it receives input from the olfactory receptors located in the nose. The olfactory bulb is a key part of the olfactory system, which is responsible for detecting and identifying odors.
The pituitary gland, also known as the hypophysis, is a small endocrine gland that is located at the base of the brain, near the hypothalamus. The pituitary gland is considered the "master gland" of the body because it produces several hormones that regulate the activity of other endocrine glands, such as the thyroid and the adrenal glands.

5. Describe the metabolic pathways in the monarch butterfly that take advantage of milkweed nectar to convert it into an energy currency.
A) Include details about the three phases of cellular respiration as they relate to sugar metabolism.
B) Where (or how) would sucrose enter the pathways?
Milkweed nectar is rich in a sugar, which is called sucrose. This sugar is a disaccharide, made of glucose and fructose. Sugar is broken down into glucose and fructose in the body, using an enzyme called invertase.
The three phases of cellular respiration are as:
Glycolysis is the process by which glucose is converted into energy. In glycolysis, two ATP molecules are made per glucose molecule. Two NADH molecules are also made. Aerobic organisms, such as monarch butterflies, can further process sugars. In the mitochondria, one CO₂ molecule is removed from the sugar, and one NADH is produced.The Kreb cycle is a series of eight enzymatic reactions that produce energy in the form of ATP. In the Kreb cycle, acetyl-CoA is completely oxidized to produce carbon dioxide. This process is aided by the production of NADH, FADH₂, and a molecule of GTP. Oxaloacetate is regenerated to continue the cycle.Oxidative phosphorylation is the process that generates a proton gradient across the inner mitochondrial membrane. This gradient is used by the V ETC complex to generate energy. The V ETC complex is located in the inner mitochondrial membrane, and as protons flow back and forth through the complex, it catalyzes the phosphorylation of ADP to produce ATP.Learn more about cellular respiration https://brainly.com/question/14158795

What would happen if the active site of an enzyme has a different shape ?
If the enzyme changes shape, the active site may no longer be able to bind to the right substrate, which would slow down the activity. In response to abrupt pH and temperature fluctuations, enzymes eventually denature.
Enzymes accelerate processes by reducing the activation energy of certain reactions, just like other catalysts do. The rate of substrate to product conversion can be multiplied by ten by some enzymes. Orotidine 5'-phosphate carboxylase is an extreme example, accelerating a reaction from millions of years to milliseconds. Enzymes are similar to any catalyst chemically speaking and neither consume substances in chemical reactions nor change the equilibrium of a reaction. Enzymes are much more specialized catalysts than the majority of other catalysts.

Which structure fuses to form a diploid zygote during sexual reproduction?
Answer:During sexual reproduction, two haploid cells, called gametes, fuse to form a diploid cell called a zygote. In animals, the gametes are sperm and eggs, and the process by which they fuse is called fertilization. In plants, the gametes are produced by the male and female reproductive cells, called the microgametes and the megagametes, respectively, and the process is called syngamy.
During fertilization in animals, the sperm penetrates the egg, and the nuclei of the sperm and egg fuse, combining their genetic material. This forms the diploid zygote, which then undergoes cell division to form a multicellular organism.
In plants, the fusion of the microgametes and megagametes occurs at the tip of the pollen tube and the egg cell. This process is called double fertilization, which leads to the formation of a diploid zygote and a triploid cell called the endosperm, which provides nourishment for the developing seed.
In both case, sperm and egg or micro and mega gametes are the structure fusing to form diploid zygote during sexual reproduction.
What are examples of environmental variations?
Examples of environmental variations:
Hair length: The length at which you want to wear your hair.Scars from your own accidents .Your muscle strength is based on how much exercise you get.Piercings: whether you decide to get them or not.Environmental variation refers to an organism's capacity to significantly vary its PHENOTYPE in response to environmental factors. Plants exhibit the phenomenon the most clearly, possibly because they are permanently rooted in the earth. For instance, if a dandelion is planted in a garden border with other plants, it will develop an upright posture with long blossom stalks. If cultivated on a garden lawn, a different dandelion with a similar genotype will result in a PROCUMBENT habit with short flower stalks.
Climate, diet, accidents, culture, and way of life are only a few examples of the variables that might have an impact on an animal's or plant's characteristics. For instance, you will put on weight if you eat too much, and you will lose weight if you eat too little.
