The features common for plasmodesmata and gap junctions are, In that they serve as conduits for the passage of ions, nutrients, and other materials that allow cells to communicate, gap junctions in animal cells are similar to plasmodesmata in plant cells.
What are the difference between plasmodesmata and gap junction ?Plasmodesmata (PD) are gated plant cell wall channels that facilitate the movement of chemicals between cells. They are crucial for plant development as well as the coordination of cellular and systemic signaling responses during interactions between plants and their biotic and abiotic surroundings.
The body contains various locations where gap junctions can be detected. This contains the nerves, cardiac (heart) muscle, and smooth muscle that coat the surfaces of the body.
Between every pair of plant cells, there is a channel called plasmodesma that cuts through the cell wall. In contrast to gap junctions, where one cell's plasma membrane is separated from another by a gap, a plasmodesma's plasma membranes are joined together, creating a small space between them.

If a cell is placed in a hypertonic sodium chloride (salt) solution, which TWO actions will be the MOST LIKELY result from the cell attempting to maintain homeostasis?
Salt will move by osmosis out of the cell.
Water will move by osmosis out of the cell.
Salt will move by active transport out of the cell.
Water will move by active transport into the cell.
The cell will shrink (crenation) as water moves between the environments to reach equilibrium.
The two actions that will most likely result from the cell attempting to maintain homeostasis are as follows:
Salt will move by active transport out of the cellWater will move by active transport into the cellWhat is a hypertonic solution?A hypertonic solution is a solution having a greater osmotic pressure than another solution. In this case, a cell is said to be placed in a hypertonic sodium chloride solution.
This means that there is more salt (solute) in the extracellular solution than in the intracellular solution.
Naturally, this will induce the movement of water molecules from the cell into the extracellular solution causing the cell to eventually shrink.
However, to maintain homeostasis, the cell can make use of active transport, which is the movement of ions or molecules across a cell membrane into a region of higher concentration, assisted by enzymes and requiring energy.
The active transport will be used to move water into the cell and move salt out of the cell.

The coyote can be categorized as a tertiary consumers, the photo does not indicate that this animal is an omnivore.
What are consumers in an ecosystem?The consumers in the trophic chain are animals that cannot produce their own food and therefore they need to eat other organisms to survive. Coyotes are tertiary consumers because they eat other animals located at the third level, instead of plants as occurs with herbivores (the first level of consumers in the trophic chain).
Moreover, omnivores are animals that eat both plants and animals, but coyotes do not eat plants.
Therefore, we can conclude that coyotes are classified as tertiary consumers in the trophic chain and they are not omnivores because do not consume plants but only other animals that are present in the trophic chain.

do unbalanced forces have zero net force
Answer: No, unbalanced forces do not have zero net force.
Explanation: For there to be a zero net force, the forces have to cancel each other out, but if they’re uneven (with one being greater than the other), then the greater force will “dominate”. Imagine two people are pushing each other at the same time. If they’re pushing each other with the same force, neither will move, and that’s zero net force. But if one of them has a stronger push, then it would cause them to move in the direction the stronger person is pushing.

what are the types ?
Fats are a subgroup of compounds known as lipids that are found in the body and have the general property of being hydrophobic (meaning they are insoluble in water). Fats are also known as triglycerides, molecules made from the combination of one molecule of glycerol with three fatty acidsThe main purpose of fats in the body is to serve as a storage system and reserve supply of energy. During periods of low food consumption, fat reserves in the body can be mobilized and broken down to release energy. Fats serve as an insulation material to allow body heat to be conserved and fats line and protect delicate internal organs from physical damage. Fats in the diet can be converted to other lipids that serve as the main structural material in the membranes surrounding our cells. Fats are also used in the manufacture of some steroids and hormones that help regulate proper growth and maintenance of tissue in the body.Fats can be classified as either saturated or unsaturated depending on the structure of the long carbon-carbon chains in the fatty acids.Saturated Fats: Fats that contain no double bonds in their fatty acid chains are referred to as saturated fats. These fats tend to be solid at room temperature, such as butter or animal fat. The consumption of saturated fats carries some health risks in that they have been linked to arteriosclerosis (hardening of the arteries) and heart disease.Unsaturated Fats: Unsaturated fats contain some number of double bonds in their structure. These fats are generally liquid at room temperature (fats that are liquid at room temperature are referred to as oils). Unsaturated fats can be either polyunsaturated (many double bonds) or monounsaturated fats (one or few double bonds). Recent research suggests that the healthiest of the fats in the human diet are the monounsaturated fats, such as olive oil and canola oil, because they appear to be beneficial in the fight against heart disease.To learn more about fats refer:

Answer:
correlational; unable
Explanation:
hope it helps
The investigator will be unable to assert that having a certain blood type causes one to be more prone to disease X.
The scientific method is a process of gathering evidence to test a hypothesis. In this case, the hypothesis would be that there is a relationship between blood type and disease X. The investigator would gather data by collecting information on the blood types of people with disease X and people without disease X. She would then analyze the data to see if there is a statistically significant difference in the blood types of the two groups.
If the investigator finds a statistically significant difference, she can conclude that there is a relationship between blood type and disease X. However, she cannot conclude that having a certain blood type causes one to be more prone to disease X. There could be other factors that explain the relationship, such as environmental factors or lifestyle choices.
The only way to definitively prove that having a certain blood type causes one to be more prone to disease X would be to conduct an experiment in which the investigator manipulates blood type. However, this is not possible, as blood type is a genetic trait that cannot be changed.

Five fundamental processes by which nitrogen is fixed through the biosphere, air, and geosphere are nitrogen fixation, nitrogen take-up through organismal development, nitrogen mineralization through rot, nitrification, and denitrification.
Nitrogen fixation is the method wherein N2 is changed over to ammonium, or NH4+. Usually, the as it were way that living beings can achieve nitrogen straightforwardly from the environment; the few that can do this are called nitrogen-fixing life forms.
Certain microscopic organisms, counting those among the class Rhizobium, can settle nitrogen.
The ammonium (NH4+) delivered by nitrogen-fixing microbes is as a rule rapidly taken up by a plant, the microbes itself, or another soil living being and consolidated into proteins and other natural nitrogen compounds, like DNA.
After nitrogen is consolidated into the natural matter, it is regularly changed over back into inorganic nitrogen by a preparation called nitrogen mineralization, something else known as decay.
A few of the ammonium created by decay is changed over to nitrate (NO3-) using a preparation called nitrification.
Denitrification is an anaerobic preparation that's carried out by denitrifying microbes, which change from nitrate to dinitrogen.
