circulatory system
muscular system
skeletal system
Which system should also be included in the list?
(1) immune system (3) digestive system
(2) reproductive system (4) nervous system
Answer:
4.) Nervous System
Explanation:
Nervous system helps in nervous coordination and it is the system that provide communication to all the parts of the body through electrical and chemical impulses.The two nervous system are;
1.)Central nervous system(CNS)
2.)peripheral nervous system(PNS).
The central nervous system control all behaviors and its is the largest part of the nervous system, with inclusion of the brain and the spinal cord.
Nervous system have communication with several other body systems
For instance, when we run the nervous system send message directly to other part of our body system such as; The circulatory system,muscular system and the skeletal system about the activities that is about to take place and that the Skeletal muscles need neural inputs to begins it's contraction.
Answer:The correct option is C) Cell walls are rigid. Small molecules like water or oxygen can pass through them.
Explanation:
Cell walls are found in plant cells and some other organisms. They provide structural support and protection to the cell. The cell wall is made up of a rigid material called cellulose, which gives it its strength.
Cell walls are permeable, meaning that they allow certain substances to pass through them. Small molecules like water and oxygen can pass through the cell wall via small pores or channels. However, larger molecules, such as proteins and carbohydrates, cannot pass through the cell wall.
This selective permeability of the cell wall allows the cell to control the movement of substances in and out of the cell, maintaining its internal environment. It also helps prevent the cell from bursting under osmotic pressure.
In summary, cell walls are rigid structures composed of cellulose. They are permeable, allowing small molecules like water and oxygen to pass through, while blocking larger molecules.
b. hormone mimics
c. plastics precursors
d. industrial byproducts
Answer:
Endocrine disruptors are the synthetic or natural chemicals that may interfere with the functioning of the endocrine system in the human body. These chemicals mimic the naturally occurring hormones produced in the body like estrogen (a female sex hormone) and androgen (a male sex hormone) also these interfere with the production of the thyroid hormone. They bind to the receptors present in a cell and prevents the endogenous hormone from binding. The normal signaling process fails to respond properly.
Chemicals that functions as endocrine disruptors include dioxine, polychlorinated biphenyls (PCBs), pesticides and DDT.
Answer:
Its B- Hormone Mimics
b.internal fertilization
c.pollination
just wanted to let you all know that the answer isnt b..... chose that and got it wrong. have a good day yall!
Common names for species can be ambiguous and vary depending on cultural, regional, and language differences. This can lead to confusion when referring to or studying a species. To prevent this, scientists use a unified naming system called binomial nomenclature, ensuring each species has a universally recognized name.
Common names are not a good reference to a species because they can be ambiguous and vary depending on location, culture, and language. They are also known as folk taxonomy or ethnotaxonomy. These names can lead to confusion because different species might have the same common name in different regions, making it challenging for scientists to discuss and study these species universally.
For instance, consider a species bright red butterfly commonly referred to as the 'red admiral' in one region. In another part of the world, a different species of butterfly exhibiting a similar hue of red might also be called a 'red admiral'. This causes confusion as two different species are referred to by the same common name in different regions.
To avoid this confusion, scientists use a universal naming system known as the binomial nomenclature. Established by Carl Linnaeus, this system provides each species a unique name composed of two parts: the genus name and the species name. For example, the binomial name for humans is Homo sapiens. This naming system ensures that regardless of location, culture, and language, the scientific community can accurately refer to and study species.

Common names are not a good reference to a species because they can vary greatly in different ways. Scientific names based on the binomial nomenclature provide a universally recognized and standardized way to refer to species.
Common names are not a good reference to a species because they can be in different languages, vary with location, vary with culture, and vary with species color. Unlike common names, scientific names based on the binomial nomenclature provide a universally recognized and standardized way to refer to species. For example, the scientific name for the North American blue jay is Cyanocitta cristata. This system avoids confusion caused by regional and colloquial names.
