Scenario: You want to determine whether plants communicate with their neighbors in response to stress, so you design an experiment. You have two groups of plants, one that will be exposed to a stressor and another that will not. You apply the stress 3 times a day for 10 days. At day 1 you measure the amount of stress hormone in the plants and then again you measure the amount of stress hormone on day 10.
Answers
Here, the hypothesis is "plants communicate with their neighbors in response to stress", dependent variable is the amount of the stress hormone in the plants, and the independent variable is the exposure to stress (applied 3 times a day for 10 days), standardized variables are plants used, duration of the stressor, amount of stress hormone. The control group is the plant that is not exposed to stressor.
What is the significance of the control group?Here, the control group is the group of plants that are not exposed to stress, and the control groups plants are experimented or tested with the other plants to get the result of the stress hormone on the plants.
Hence, here, the hypothesis is "plants communicate with their neighbors in response to stress", dependent variable is the amount of the stress hormone in the plants, and the independent variable is the exposure to stress (applied 3 times a day for 10 days), standardized variables are plants used, duration of the stressor, amount of stress hormone.

Answers
Answer:
Homeostasis.
Explanation:
A characteristic of living organisms is their ability to maintain internal balance. Therefore, maintaining internal balance inside the body is known as homeostasis.
Homeostasis can be defined as a process through which a living organism maintains a steady or stable physical, internal and chemical environment ideal to enhance life and proper functionality.
For example, if a person becomes infected with a pathogen such as a virus. The internal stimulus that most likely takes place in order for their body to maintain homeostasis is that their core temperature increases. This is because pathogens such as a virus do not thrive or survive in a hot environment; they're naturally allergic to high temperature (heat).

The tree grew 74 kg, although the soil did not change considerably over the course of five years, indicating that the tree's bulk was not solely derived from the soil. The soil would have lost a comparable amount of mass if the tree had gained all of its weight from the soil, but this did not happen. This information thus implies that a tree's bulk is not exclusively derived from the earth.

A mouse eats 100 times his own weight in grain in a lifetime. You can see that plants must produce a great amount of food for just one mouse. What do you think would happen if grain was no longer available for the mouse to eat? How would it affect other organisms in your ecosystem?
Answers
Answer:
Producers:
Acorns (produced by oak trees)Apples (produced by apple trees)Cabbage (a leafy green vegetable cultivated as an annual plant)Potatoes (tubers produced by the potato plant)Carrots (root vegetables, usually orange in color)Grains (wheat (produced by wheat plants), barley (produced by barley plant), etc.)Grass (produces seeds and is a primary food source for many herbivores)Corn (a cereal plant that yields large grains, or kernels, set in rows on a cob)Lettuce (a leafy green plant grown for its often-crunchy leaves)Trees (producing oxygen as a byproduct of photosynthesis and also yielding food items like fruit and nuts)Plant-eating Consumers (Herbivores):
Deer (eat various plants and fruits, they are herbivores)Rabbits (eat grass, roots, and leafy greens; they are herbivores)Horses (eat grass and grains; they are herbivores)Cows (eat grass and grains; they are herbivores)Squirrels (primarily eat acorns, grains, seeds, and fruits)Mice (eats mainly plants, seeds, grains, fruits, and vegetables)Chickens (often fed grains, vegetables, and fruits)Predators (Carnivores):
Eagles (predatory birds that feed on smaller animals; they are carnivores)Owls (nocturnal birds that prey on small mammals, birds, and insects; they are carnivores)Wolves (carnivorous mammals that prey on deer, rabbits, and other smaller animals; they are carnivores)Frogs (amphibians with a carnivorous diet, eating insects, small mammals, small fish, spiders, and worms)Detritivores (although not mentioned in the question, they are crucial in every ecosystem):
Worms (in general, worms are classified as detritivores).To answer your questions:
In this bulleted list, there are more producers than consumers and more consumers than predators. This is typical of most ecological pyramids because each level depends on the one below it for food. There are always fewer organisms at the top of the pyramid because energy is lost at each level due to the laws of thermodynamics.For example, squirrels can be considered both plant-eating consumers (as they eat acorns, tree bark, and fruits) and potential predators (as they can be omnivorous, eating small insects and bird eggs). Similarly, mice can be categorized as plant-eating consumers, but they can also be omnivorous, consuming insects and occasionally the remains of deceased animals.If grain was no longer available, the mouse population would be significantly affected. Mice rely heavily on grains for their energy and nutrition. If this food source were suddenly unavailable, the mice would either need to find another food source, like fruits or vegetables, or their population would likely decrease due to starvation. This change would also impact other levels of the ecosystem. Predators who rely on mice as a food source, like owls and snakes, would find fewer prey available, which could lead to a decrease in their populations as well. Conversely, without mice consuming as much grain, the grain population might increase. However, other herbivores who also eat grains might proliferate, taking advantage of the increased food source and maintaining a balance. This hypothetical situation demonstrates the delicate balance of ecosystems and the potential cascading effects that can occur from changes at any level of the food web.What kinds of ways do we make when we eat and what happens to the waist 
Answers
Answer:
Within the last half of the intestine, wastes are stored. These wastes are made up of undigested food, and dead bacteria. The wastes then become feces and are released through the anus.
Explanation:
Once all the nutrients have been absorbed, the waste is moved into the large intestine, or bowel. Water is removed and the waste (faeces) is stored in the rectum. It can then be passed out of the body through the anus.
When we eat, our body goes through a series of physiological processes to break down the food and extract the nutrients.
What happens when we eat?The act of chewing and swallowing the food begins the process of digestion. Once in the stomach, the food is mixed with digestive enzymes and acids to break it down further. The broken-down food then moves to the small intestine where the nutrients are absorbed into the bloodstream and transported to the cells of the body to be used for energy and other functions.
The unused portions of the food, such as fiber, move on to the large intestine, where water is absorbed and waste products are formed. These waste products, along with bacteria and other substances, form feces, which are eventually eliminated from the body through the rectum and anus.

Show the reciprocal cross: A red-eyed female (homozygous) and a white-eyed male. How many offspring will have white eyes and what is their sex?
Answers
When we see the reciprocal cross between a red-eyed female (homozygous) and a white-eyed male,we observe that none of the offspring will have white eyes. Additionally, the sex of the offspring will be half male and half female since the ratio of males to females is 1:1.
The reciprocal cross for a red-eyed female (homozygous) and a white-eyed male can be shown as follows:Female (XrXr) x Male (XwY). Females have two X chromosomes and males have an X and a Y chromosome. Red eyes are dominant to white eyes; therefore, we use Xr to represent red eyes and Xw to represent white eyes.
The offspring are as follows:All F1 females are heterozygous (XrXw).All F1 males are hemizygous (XrY).The F1 generation will have red eyes since the dominant allele is present.
None of the F1 individuals will have white eyes as the recessive allele is not present in the F1 generation.

What is the connective tissue?The connective tissue, also known as support tissue, supports and connects all the other tissues and organs in the body. Every substance exchange between epitheliums, muscles, nerves, and the vascular system must be done with the connective tissue as an intermediate.
According to its specialization, there are different kinds of connective tissue, such as cartilage, blood, bony tissue, or lymphatic tissue, among others. Each type of connective tissue has its own cell type according to its functions. Cellular types, fibers, and aqueous medium appear in different amounts in different parts of the organism.
The connective tissue is composed of cells that are very separated from each other because of the abundant extracellular matrix, which is produced by fibroblasts, a predominant cell population. The extracellular matrix has fibrillar proteins of different natures such as collagen, fibrillin, and elastin that determine tension properties. There are also adessive proteins such as fibronectin and laminin. All of these proteins are included in a medium that contains water, salts, GAGs, proteoglycans, glycoproteins, and other macromolecules that confer turgidity and facilitate diffusion. The properties of this matrix in different connective tissues mark the difference between each other.
The connective tissue originates in the mesoderm, which in the early stages of development, differentiates from an embryonary connective tissue called mesenchyme.
