Answer:
1.A Golgi body, also known as a Golgi apparatus, is a cell organelle that helps process and package proteins and lipid molecules, especially proteins destined to be exported from the cell.
2.The plasma membrane, or the cell membrane, provides protection for a cell. It also provides a fixed environment inside the cell, and that membrane has several different functions. One is to transport nutrients into the cell and also to transport toxic substances out of the cell.
3.The cytocenter or centrosome is a cellular organelle that is not surrounded by a membrane; ... " centrosome- related bodies " (CRBs for centrosome- related bodies) are often seen at ectopic sites.
4.The nucleus is a membrane-bound organelle that contains genetic material (DNA) of eukaryotic organisms. As such, it serves to maintain the integrity of the cell by facilitating transcription and replication processes. It's the largest organelle inside the cell taking up about a tenth of the entire cell volume.
5.A vacuole is a membrane-bound cell organelle. In animal cells, vacuoles are generally small and help sequester waste products.

D) Circulatory system is not an organ. It refers to a system composed of organs (such as the heart, blood vessels, and blood) that work together to transport substances throughout the body. So, option D is the right choice.
The circulatory system is a complex network of blood vessels, the heart, and blood. It is responsible for transporting oxygen, nutrients, hormones, and waste products throughout the body.
The heart (option A) is an organ that pumps blood and helps circulate it throughout the body.The brain (option B) is an organ that controls various bodily functions, processes information, and regulates the nervous system.The stomach (option C) is an organ involved in the digestion of food.The circulatory system (option D) is not an organ itself but rather a system composed of organs, including the heart and blood vessels, that work together to transport substances.The kidneys (option E) are organs responsible for filtering waste products from the blood and producing urine.Therefore, among the given options, D) Circulatory system is the correct answer as it does not represent an individual organ but a system comprising multiple organs.

Where does the external respiration take place in pets?
Answer:
In mammals (like cat and dog pets), external respiration takes place by the exchange of gases in the alveoli of the lungs
Explanation:
External respiration refers to the process of exchange of gases, i.e., oxygen (O2) and carbon dioxide (CO2), with the environment. In mammals like humans, dogs and cats, external respiration occurs in the millions of alveoli in the lungs and the capillaries that are located in the walls of the alveoli. This process (gas exchange) happens due to simple diffusion. The O2 is taken from the environment (by inhalation) and travels from the alveoli to the blood in the capillaries that surround the alveoli, while and CO2 diffuses from the blood capillaries to the alveoli (where this gas is exhaled).

Scientists can learn all of the following by studying fossils EXCEPT:
Question 2 options:
How life forms have changed over time
How the environment has changed over time
How the surrounding rock layers have changed over time
How the Erath's surface has changed over time
Answer: How the surrounding rock layers have changed over time
Explanation:
I’m taking a minion quiz in science class and I submitted it and we’ll that’s the correct answer
The changes in surrounding rock layers over time cannot be studied by fossils. So the correct option is C.
What are the uses of fossils?We can learn a lot about the Earth's history of life thanks to fossils. They can help us understand the origins of life and humanity, the evolution of the planet and its environment across time, and the once-connected nature of the continents that are now widely separated.
Important evidence for evolutionary and the environmental adaptability of plants and animals may be found in fossils. Fossil evidence shows how organisms developed and how a "tree of life" may be used to illustrate this process, demonstrating the interconnectedness of all species.
Rocks can also be dated using fossils. Geologists may use fossils to study geological history because different types of fossils appear in rocks of various ages as a result of evolution. Fossils are one of the most crucial instruments for age correlation in geology.
Ammonites, for instance, are great reference fossils for stratigraphy because they may be used to compare the relative ages of two or more strata, or layers of rock, that are located in various locations across the same nation or elsewhere in the world.
Therefore, the correct option is C.

What is another term for the responding variable?
O primary variable
dependent variable
independent variable
uncontrolled variable
The answer is DEPENDENT VARIABLE
-edgy 2021
Answer:
B. Dependent variable.
Explanation:
An experiment can be defined as an investigation which typically involves the process of manipulating an independent variable (the cause) in order to be able to determine or measure the dependent variable (the effect).
Hence, an experiment is used by scientists or psychologists to illustrate how a change in variable affects behavior.
This ultimately implies that, an experiment can be used by scientists to show or demonstrate how a condition causes or gives rise to another i.e cause and effect, influence, behavior, etc in a sample.
In an experiment, there are two (2) main types of variables and these are;
I. Independent variable: this is the variable that is being manipulated or alters and as such it is the cause of a behavior. This variable stands alone.
II. Dependent variable: this variable is the direct effect of the actions of the researcher in an experiment.
Basically, the dependent variable is the variable that is being measured and tested by an experimentalist.
Hence, dependent variable is another term for the responding variable because it responds to an action.
2. Which organisms should be the least common?
Answer: The illustration is missing the type of organisms known as decomposers. They break down dead animals and plants and have the vital role in returning the nutrients back into the system, where they can be used once more by the primary producers.

The immune system has two modalities, specific and nonspecific responses. Which of the following is an example of a nonspecific response?
A. an antigen binding to an antibody
B. inflammation at the site of an infection
C. a cytotoxic T cell attacking a pathogenic agent
D. lymphocytes activating plasma cells in the blood
B. Inflammation at the site of an infection is an example of a nonspecific response of the immune system.
What is non-specific immune response?Non-specific immune responses, also known as innate immunity, are the first line of defense against invading pathogens and are activated immediately upon exposure to a foreign invader. These responses are not specific to a particular pathogen and do not require previous exposure or recognition. Instead, they provide a general response that helps to prevent the spread of the pathogen and contains it until the specific adaptive immune response can be activated.
Examples of non-specific immune responses include physical barriers such as skin and mucous membranes, as well as physiological responses such as inflammation, fever, and the activity of phagocytic cells like macrophages, which engulf and destroy pathogens. Non-specific immune responses also include natural killer cells, which are able to recognize and kill infected cells, and the complement system, a group of proteins that help to enhance the ability of other components of the immune system to destroy pathogens.
