Which sequence shows a decreasing level of complexity?
Hello. This question is incomplete. The full question is:
" Which sequence shows a decreasing level of complexity? 1) organs organism cells tissues , 2) organism cells organs tissues , 3) cells tissues organs organism , 4) organism organs tissues cells"
Answer:
4) organism organs tissues cells
Explanation:
The order "organism, organs, tissues, cells" shows the levels of organization in a decreasing level of complexity.
There are several hierarchical levels of organization among living beings, starting with atoms and ending with biomes. Each of these levels is a matter of study for biologists. These levels are:
Atoms: a very small part of matter. Atoms are divided into protons, neutrons and electrons. The joining of these atoms forms matter in its solid, liquid and gaseous states. Molecule: the molecule is a junction of atoms. The molecules are diverse substances and are formed by different atoms (H2O) or by the same atoms (O2); Organelle: small organ-like structures that are present in animal and plant cells. They help to carry out the vital functions of cells; Cell: cells are the functional units that make up animal and plant organs. They perform breathing and reproduction in addition to saving the genetic information of beings; Tissue: is the visible part of the organs, formed by a group of plant or animal cells. Our skin, for example, is a type of tissue. Tissues are responsible for storing cells, blood vessels, making excretions such as sweat.Organs: set of tissues. The organs perform various types of functions: the heart pumps blood, the stomach helps with food, the small intestine absorbs substances. System: set of interconnected organs. Our digestive system, for example, has a mouth, tongue, esophagus, stomach and intestine. Organism: set of systems that form a living being, for example, the human being, a lion, a plant.How many protons and electrons does magnesium have

Why are lipids able to function as protective barriers in cells?
Final answer:
Lipids function as protective barriers in cells due to their hydrophobic nature, forming phospholipid bilayers in cell membranes that prevent unregulated passage of substances while allowing selectivity through embedded proteins.
Explanation:
Lipids are able to function as protective barriers in cells because of their hydrophobic nature. Being largely nonpolar compounds, they consist predominantly of nonpolar carbon-carbon or carbon-hydrogen bonds, making them insoluble in water. This hydrophobic quality is crucial for their role in cell membranes where they form phospholipid bilayers that act as barriers, preventing the passage of many substances into and out of the cell. Furthermore, these lipids, including cholesterol, phospholipids, and other types of lipids like fats and waxes, serve various functions such as energy storage, insulation, and the composition of hormones. Specifically, the phospholipid bilayer in cell membranes is integral to maintaining a hydrophilic exterior and interior suitable for the aqueous cell environment, while also housing various proteins for selective substance transport.
An herbivore might eat all of the following except
A. Ants
B. Algae
C.ferns
D.leaves
Answer:
A. Ants
Explanation:
Herbivorous animals are those that consume live plants or part of them. In this way, ecologically speaking, they can play a role as predators, by removing individuals from the population; or parasites, for consuming certain plant structures, but without killing them. Accordingly, we can say that herbivores can eat algae, ferns and leaves, but do not feed on ants.
Considering these facts, herbivores are able to control some plant populations by reducing their growth and reproduction rates. For this reason, some insects with this feeding habit are used to control the growth of plantation pests.
The region of the optic nerve lacking photoreceptor cells is known as the ________.
The blind spot, also known as the optic disc, is the region in the retina where the optic nerve exits the eye, and it lacks photoreceptors, creating a part in our vision where we cannot perceive light.
The region of the optic nerve lacking photoreceptor cells is known as the blind spot. Specifically, this region is called the optic disc, where the ganglion cell axons exit the retina to form the optic nerve. No photoreceptors are present at this location, resulting in an absence of vision for light that falls onto this part of the retina.
The fovea, by contrast, is the area of the retina with the greatest visual acuity and consists mainly of cone photoreceptors. Unlike the blind spot, the fovea allows for sharp images to be perceived due to its high density of photoreceptors.

Explanation: Position D in the image represents the summer solstice. It is the condition when the sun is directly overhead the tropic of cancer (the gulf of California). It takes place on round 22nd of June every year, in which the norther hemisphere experiences summer solstice and the southern hemisphere experiences winter solstice.

The nurse is caring for a client who has a tracheostomy tube with a high-volume, low-pressure cuff. what does the cuff prevent?
According to the scenario, the cuff that prevents the process is known as Mucosal necrosis.
When should you deflate the cuff on a tracheostomy?The cuff will definitely deflate the mechanisms of tracheostomy when neither mechanical ventilation nor a risk of gross aspiration is present. Another consideration is to change the patient to a cuffless tracheostomy tube. The definition of aspiration is when any food, liquid, or other matter passes below the vocal folds.
According to the context of this question, if an individual is used to inflate the cuff, he/she needs to inject air into the adaptor at the end of the pilot balloon. Inject the least amount of air needed in order to adequately create a seal around the tube. The amount of air necessary will vary depending on the diameter of the tracheostomy tube and the patient's trachea.

The right answer is mitosis, diploid cells and identical dna.
Asexual reproduction is a form of reproduction of an already developed living being in which, from a cell or a group of cells, is developed, by mitotic processes, a complete individual, genetically identical to the first. It is performed with a single progenitor and without intervention of the nuclei of the sexual cells or gametes.

In a eukaryotic cell, transcription takes place _____. in the nucleus in the rough endoplasmic reticulum on free ribosomes on the cell membrane in the cytoplasm
In a eukaryotic cell, transcription takes place in the nucleus .Transcription is the process by which genetic information encoded in DNA is used to synthesize RNA molecules.
The nucleus is a membrane-bound organelle found in eukaryotic cells that contains the cell's DNA. Within the nucleus, DNA is organized into structures called chromosomes. Transcription involves the enzyme RNA polymerase binding to a specific region of DNA called the promoter. The DNA double helix unwinds, and RNA polymerase uses one strand of the DNA as a template to synthesize a complementary RNA molecule known as pre-mRNA.
The pre-mRNA molecule is then processed through a series of modifications, including the addition of a cap structure at one end and a poly-A tail at the other. Additionally, non-coding regions called introns are removed, and the remaining coding regions called exons are spliced together. These modifications produce a mature mRNA molecule that can be transported out of the nucleus and into the cytoplasm for further processing and translation.
