Hormones can act on the cell that produces them, neighboring cells and distant cells after passage in the blood. Discuss whether it si possible for a single molecile to work via all three effector routes.
Answer and Explanation:
Yes, a single molecule can work through all three effector route. Cells commonly lead independent lives, and they might influence and communicate with other cells for sexual mating. For example, yeast cells communicate with one another for mating. On the other hand, animal cells communicate by different kinds of signal molecules. These molecules include amino acids, nucleotides, proteins, small peptides, retinoid, and derivatives of fatty acids and also includes dissolved gases such as carbon monoxide and nitric oxide. In the extracellular spaces, most signal molecules are secreted by the signaling cells. Some signal molecules are exposed to the extracellular spaces, while others are released by diffusion. Target cells respond by a specific protein called receptors. Receptors bind the signal molecules and start response in the target cell. On the surface of target cells, receptors are transmembrane proteins. When receptors bind extracellular signal molecules, they stimulated and produced a flow of intracellular signals that initiate the cells' behavior.

Which statement about chromosomes and biological sex is correct?
Males are XX
Females are XY
Males are XY
Answer:
Males are XY
Explanation:
When looking at the male karyotype, we can see that the last set of chromosomes (the sex chromosomes) is composed of a full-sized chromosome and a smaller, half-sized chromosome. The full-sized chromosome is called an X chromosome and the half-sized chromosome is called a Y chromosome. Males are XY and females are XX. I hope this helps :)

Which definition best describes an acid?
Answer:
A substance in a solution that releases and captures hydrogen ions, keeping the pH the same
Explanation:
A substance that may release a proton or hydrogen ion (H +) is referred to as an acid.
What is acid?Hydrogen ions and chloride ions are created when hydrogen chloride, which is suspended in water, ionizes. A particle or ion that may produce a hydron (proton or hydrogen ion H+ is known as an acid.
Any hydrogen-containing material that has the ability to donate a proton (hydrogen ion) to another chemical is considered an acid. A base is a molecule or ion that can take up an acid's hydrogen ion.
Typically, sour tastes help to identify acidic chemicals. capable of forming a covalent connection with an electron pair on (a Lewis acid). Proton donors, also known as Brnsted acids, make up the first level of acids.
Therefore, that may release a proton or hydrogen ion (H +) is referred to as an acid.

What must be done to coal before it can be used as fuel?
It must be made to stick together.
It must be compressed into a very dense substance.
It must be ground into powder.
It must have flammable material added to it.
Answer:
It must be ground into powder.
Explanation:
"Coal" is one of the nonrenewable resources that humans use for fuel. In order to produce energy, it needs to be burned first. However, efficient combustion happens when the coal is pulverized into fine powder first. This allows the coal to mixed with hot air sufficiently in order to release heat. This then allows the "generation of electricity" that is often used for cooking, lighting, cooling, transportation, healthcare, etc.
NASA has discovered a lifeform on another planet! They have called you to help them identify what kind of organism it is. Which features suggest that the lifeform is eukaryotic rather than prokaryotic
Answer:
Nucleus, Linear Chromosomes, membrane-bounded organelles, golgi apparatus, mitochondria
Explanation:
All life forms consists of either prokaryotic cells or eukaryotic cells.
An Eukaryotic cell is a cell which has a nucleus. They are a group of organisms which have a nucleus that is enclosed inside a nuclear envelop. They contains member bound organelles which includes the mitochondria, endoplasmic reticulum and the nucleus. Some of the examples of eukaryotic cells are plants, animals, protists, fungi, etc.
Where as a prokaryotic cells does not contains a nucleus. They do not have a member bound organelles. Prokaryotic are unicellular. Some examples are bacteria, archaea, etc.
In the context, I would look for features such as membrane bounded organelles, mitochondria, nucleus, golgi apparatus, etc. in the new life form that has been discovered in the new planet to identify them as eukaryotic.

Design an experiment that would directly test the hypothesis of the following scenario. Identify the control group, independent variable, and dependent variable.
Hypothesis: The plant species Acidicus plantus grows best at pH 2-4.
Answer:
My experiment would consist of two different treatments: pH 2-4 and pH 5-7.
In this case:
- Control group: Acidicus plantus plants growing in different conditions (pH 5-7)
- Independent variable: pH
- Dependent variable: plant growth
Explanation:
A control group is a group in which the effects of a given treatment are unknown, so the control group can be used to compare with the experimental group. In this case, Acidicus plantus plants growing in different conditions can be used as the control group, since this group can be used to measure the effects of the treatment. The dependent variable is the variable that is being measured in the experiment (in this case, plant growth), while the independent variable is the variable that isn't modified by the other variables measured in the experiment (in this case, pH).

Answer:
It depends on the location on the periodic table and if it is easier to loose are gain electrons to fill the valence electron shell.
The electron affinity of the neutral atom of the element can show indicate whether or not the element is going the make positive or negative ions. The higher the electron affinity is, the more the neutral atom wants to gain electrons. The electron affinity for alkali metals and alkaline earth metals are low due to the fact that they are located on the left of the periodic table and only needs to loose 1 or 2 electrons to have a completed valence shell. That means that they want to form cations (loose electrons). Halogens have a high electron affinity since they are located on the right of the periodic table and only have to gain 1 electron to get a completed valence electron configuration. That means that it forms anions.

Negative pressure rooms are sometimes referred to as source isolation rooms, while positive pressure rooms are sometime called protective isolation rooms. Explain the thinking behind these names.
Answer:
Negative pressure rooms are sometimes referred to as source isolation rooms because they prevent potentially contaminated air to exit the room.
Positive pressure rooms are also known as protective isolation rooms because they prevent the entering of any pathogen in the air to the room where a patient with a compromised immune system is staying.
Explanation:
Negative pressure rooms or source isolation rooms have lower pressure than the outside. Due to this pressure difference, air can enter the place but can not leave it, trapping the pathogens. Patients with infectious conditions are in these rooms to prevent the spreading of the disease. That is why they are also called source isolation rooms. These rooms have a system that filtrates and circulates the air.
On the other hand, in positive pressure rooms, the air pressure is higher. As a result, the air, with any potential bacteria, virus, or particles, leaves the room to keep the patient safe. They are also known as protective isolation rooms because patients with a compromised immune system are there to protect them from any pathogens in the air.
