All of the above statements describes scientific theory
Answer: Option D
Explanation:
A scientific theory is a clarification of a part of the characteristic world that can be more than once tried and confirmed as per the logical strategy, utilizing acknowledged conventions of perception, estimation, and assessment of results. Where potential, hypotheses are tried under controlled conditions in an examination.
In conditions not amiable to trial testing, speculations are assessed through standards of deductive thinking. Set up logical speculations have withstood thorough examination and epitomize logical information. The importance of the term scientific theory as utilized in the control science that is altogether unique in relation to the basic vernacular utilization of theory.
In ordinary discourse, the hypothesis can suggest a clarification that speaks to an unconfirmed and theoretical guess, while in science it depicts a clarification that has been tried and broadly acknowledged as substantial. These various utilization are practically identical to the contradicting uses of forecast in science versus basic discourse, where it signifies a simple expectation.
What term describes the ability of an animal to know the meaning of the signals it sends and receives?
behavior
instinct
communication
cognition
Answer:
I am thinking it is cognition..
cognition-the mental action or process of acquiring knowledge and understanding through thought, experience, and the senses.
If not it will be instinct
Explanation:
Answer:
The correct answer is cognition.
Explanation:
Cognition in animals is a process by which animals get information and learning by using their experience, senses, intelligence, perception, memory.
It gives the ability of an animal to know the meaning of the signal it sends and receives by using its senses and experience. The ability of cognition is very much important for animals because it helps them to differentiate between dangerous and non-dangerous chemical signals.
It also helps them to know their territory by marking through chemical signals in their territory and getting their mates. Therefore the correct answer is cognition.
What is the first step of the Calvin-Benson cycle?
ATP and NADPH combine to make G3P.
G3P is used to make glucose and other
compounds.
ATP and G3P combine to make RuBP.
Carbon dioxide and RuBP combine to make PGA.
The first step of the Calvin cycle is the combination of carbon dioxide with RuBP to produce PGA. This step is catalyzed by the enzyme RuBisCO and is the initial act of carbon fixation in the photosynthetic process of converting atmospheric carbon dioxide into glucose.
Explanation:The first step of the Calvin-Benson cycle, also known simply as the Calvin cycle, involves the enzyme RuBisCO fixing carbon dioxide to a five-carbon molecule called ribulose biphosphate (RuBP). This reaction produces two molecules of 3-phosphoglycerate (PGA). Therefore, the correct first step of the Calvin-Benson cycle is: Carbon dioxide and RuBP combine to make PGA.
The Calvin cycle is a process of photosynthesis where ATP and NADPH, produced in the light-dependent reactions, provide the energy to convert carbon dioxide from the atmosphere into organic compounds like glucose. Throughout the cycle, the energy is used to regenerate RuBP, allowing the cycle to prepare for more carbon fixation and continue the process of photosynthesis.
Describe how the branches on a cladogram show the relationships among organisms.
Answer:
relationships among organisms and evolutionary relationships for organisms with a shared common ancestor.
Final answer:
Cladograms use branches to show evolutionary relationships by illustrating how species diverged from common ancestors, with nodes representing the emergence of new traits.
Explanation:
The branches on a cladogram illustrate the evolutionary relationships among organisms by showing how groups of organisms diverged from common ancestors over time. Each branch or node represents a point where a new trait emerged, distinguishing one group from others, thereby forming a new clade. The length of the branches can indicate the amount of molecular changes that have occurred over time. As organisms evolve, they might acquire unique traits that set them apart from their ancestors, and these traits can also be represented on the cladogram.
For instance, in a cladogram that includes mammals, reptiles, and birds, the reptile clade includes birds, indicating that birds evolved from reptiles, contradicting the separate classification by Linnaeus. By observing the branching patterns and the traits at each node, we can interpret phylogenetic relationships and hypothesize how different species are related by descent.
What scientific word is used to describe a person who is deficient in one or more particular food groups?

what does the chloroplast produce during the light independent reactions of photosynthesis?
a. NADPH molecules
b. ATP molecules
c. carbohydrate molecules
d. chlorophyll molecules
Answer: c.- Carbohydrate molecules
Explanation:
-The light-independent reactions, or dark reactions, of photosynthesis are chemical reactions that convert carbon dioxide and other compounds into glucose. These reactions occur in the stroma, the fluid-filled area of a chloroplast outside the thylakoid membranes.
-These reactions use the ATP and NADPH synthesized during the exergonic light-dependent reactions to provide the energy for the synthesis of glucose and other organic molecules from inorganic carbon dioxide and water.

c. The moths are living in an environment with light trees.
d. The moths are living in an environment with dark trees.
Answer:
D) The moths are living in an environment with dark trees.
Explanation:
Answer:
Option D
Explanation:
The dark colored moths are increasing with time. This clearly indicates that the dark colored moths are able to save themselves from the predators. The predators of moth identify them only by the contrasting color of the moth and its habitat. Moths live on trees. Thus, if dark colored moths are able to survive, they might be living in habitat which could make them untraceable. Hence, it is obvious to say that dark colored moths are living on dark trees. Also the light colored moths are living on dark trees and this is the reason why they are easily identified and killed by the predators.
Thus, option D is correct

If you were to place the bear into the energy pyramid, the bear would go on level _____ and have ________ amount of energy available to it.
Answer:
The greatest in the first blank
the least in the second blank
Explanation:
In the energy pyramid, bears would be placed as tertiary consumers (or higher) and would have about 10 percent of the energy available from the trophic level below them, which is considerably less than what is available at the base of the pyramid.
If you were to place the bear into the energy pyramid, the bear would go on level tertiary consumer (or higher, depending on the specific diet of the bear) and have approximately 10 percent of the energy available to it from the level below.
Bears are typically classified as omnivores or occasionally as carnivores, depending on their diet. Assuming that producers in this pyramid have 1,000,000 kilocalories of energy, primary consumers would have 10 percent of that, which is 100,000 kilocalories. Since energy transfer between trophic levels is about 10 percent, the energy available to secondary consumers would be 10,000 kilocalories (10 percent of primary consumers), and the tertiary consumers would have approximately 1,000 kilocalories available to them (10 percent of secondary consumers). Bears, being tertiary consumers or sometimes quaternary when consuming other carnivores, would fall into the category with significantly less energy availability compared to the bottom of the pyramid.

Explain what would happen to the population of frogs if:.
a) Grasshoppers were to be killed by an insecticide? (2 marks)
The killing of grasshoppers by an insecticide would likely lead to a decline in the frog population due to decreased food availability, with potential ecosystem-wide effects. Frogs might suffer from nutritional shortages and be forced to seek out less suitable food sources, affecting their reproductive success and survival.
If grasshoppers were to be killed by an insecticide, we could predict several effects on the population of frogs that feed on these insects. First, the immediate availability of food for frogs would decrease, potentially leading to a decline in their numbers due to starvation or poor nutrition. This could put pressure on the frogs to find alternative food sources, which might not be as nutritious or abundant as grasshoppers. Additionally, the loss of grasshoppers could disrupt the local ecosystem since grasshoppers often play a role in plant pollination and the cycling of nutrients. The ecosystem dynamics could shift, causing further indirect effects on the frog population and other species within the food web. If grasshoppers are a significant food source, the decrease could directly affect frogs' reproductive success and survival rates, potentially leading to their population decline.

What role do you play in the food web?
A. Producer
B. Consumer
C. Decomposer
D. Human
Justify by explaining why the answer you chose is CORRECT AND why the other 3 are INCORRECT.
Answer:
D human because decomposer are mainly fungi and bacteria,producer are plants, consumers are every organism that eats something else it include herbivores, carnivores(animals that eat other animals), parasites (animals that live off of other organisms by harming it), and scavengers (animals that eat dead animal carcasses)
Humans play the role of a consumer in a food web as they eat other organisms to gain energy and nutrients. They do not play the role of producers or decomposers. The term 'human' alone does not specify a role in a food web.
Explanation:In the context of a food web, we humans play the role of a consumer. Consumers are organisms that eat other organisms to gain energy and nutrients. We certainly fit into this category as we eat both plant (producers) and animal species (other consumers).
Producers are incorrect because they are typically plants that make their own food through photosynthesis which humans do not do. Decomposers are also incorrect as they break down dead or decaying organisms, a role humans don't play in the food web. Lastly, while 'Human' is within the options, it is too broad a term for this question as it doesn’t specify the role that humans play.

Answer: Genes tell the body how to behave in certain ways, so there are genes that represent particular characteristics, and lack of genes or changes in them can lead to diseases and problems in the body.
Explanation:
Write the structures and functions of the following epithelial tissues,connective tissues,muscular tissues,nervous tissues
Ciliated epithelial cells. Cilia are tiny hair like structures on the surface of the cell. The hairs sweep hair, mucus, trapped dust and bacteria up to the back of the throat where it can be swallowed.
Cartilage is a soft, spongy connective tissue. The bones in a synovial joint are connected by ligaments. Ligaments are a type of connective tissue and are tough, fibrous and slightly elastic. They connect bone to bone and help keep the joint together.
Each type of muscle tissue in the human body has a unique structure and a specific role. Skeletal muscle moves bones and other structures. Cardiac muscle contracts the heart to pump blood. The smooth muscle tissue that forms organs like the stomach and bladder changes shape to facilitate bodily functions
Nervous tissue is composed of three main parts: nerves, the spinal cord and the brain. The primary function of nervous tissue is to receive stimuli and send the impulse to the spinal cord and brain. The brain sends back a response to the muscles via the nerves.
Epithelial tissue covers and lines surfaces, connective tissue binds cells and organs, muscular tissue moves the body, and nervous tissue transmits signals.
Explanation:Epithelial tissue is composed of sheets of cells that cover the exterior surfaces of the body, line internal cavities and passageways, and form certain glands. Its functions include protection, absorption, secretion, and selective permeability.
Connective tissue binds cells and organs together. It provides support, protection, and integration of body parts. Examples of connective tissue include bones, cartilage, blood, and adipose tissue.
Muscular tissue is involved in movement. There are three types of muscle tissue: skeletal muscle that is voluntary, smooth muscle that is involuntary, and cardiac muscle that is found in the heart.
Nervous tissue is responsible for transmitting electrical signals throughout the body. It enables communication between different regions of the body through nerve impulses.
