Which option describes cations?
Answer:
D
Explanation:
A cation is a positively charge ion, such as a sodium ion, as when it becomes an ion, it gives away electrons, becoming positively charged.
The opposite is an anion, which is a negatively charged ion, such as oxygen as it receives elections from the cation when forming an ionic bond.
Cations are the positively charged ions.
What are cations?A cation has more protons than electrons, consequently giving it a net positive charge. For a cation to form, one or more electrons must be lost, typically pulled away by atoms with a stronger affinity for them.
The number of electrons lost, and so the charge of the ion, is indicated after the chemical symbol, e.g. silver (Ag) loses one electron to become Ag+, whilst zinc (Zn) loses two electrons to become Zn2+.
In contrast, most nonmetallic atoms have a stronger attraction to electrons than do metallic atoms, and as a result, they gain electrons to form anions.
Therefore, Cations are the positively charged ions.

In ancient times, plant and animal remains got buried, compressed, and transformed into fossil fuels like coal. Burning these fossil fuels today will affect which biogeochemical cycle?
Which of these is a form of nonrenewable energy?
O A. Fossil fuel energy
O B. Solar energy
C. Wind energy
O D. Hydroelectric energy
Answer:
Fossil fuel energy
Explanation:
This is because oil from fossils take a millions of years to form and people won't be able to wait millions of years
Fossil fuel energy is a form of non-renewable form of energy. Thus, the correct option will be A.
What is Non-renewable energy?A non-renewable energy resource is a natural resource which cannot be readily replaced by the natural means at a particular pace which is quick enough to keep up with the consumption of the energy resource. An example of the non-renewable energy resource is a carbon-based fossil fuel. The original organic matter with the aid of heat energy and pressure generally becomes a fuel such as the oil or natural gas.
There are four major types of the nonrenewable resources which include oil, natural gas, coal, and the nuclear energy. Oil, natural gas, and coal are collectively known as the fossil fuels. Fossil fuels were formed within the Earth from the dead plants and animals over a period of millions of years and hence are named as the fossil fuels.
Therefore, the correct option will be A.

Hope this Helps!
When the two parental genotypes BB and bb are crossed, the genotype of all [tex]F_1[/tex] plants is Bb.
What is Genotype?An organism's genotype is defined as the complete set of genetic material that can also be used to refer to alleles or variants that occur in a particular gene or genetic locus.
The term "genotype" describes the genetic makeup of an organism as it describes the complete set of genes of an organism. This term can be used to refer to alleles, or variants of genes, carried by an organism.
When two organisms like BB parent crossed with bb parent, the offsprings that will produce is Bb.

What are the pros and cons of having the digestion be slower and over distance, as opposed to being quicker and over shorter distance with slightly less absorption?(40 points)
Answer:
Explanation: When you have a slow digestive system, a condition known as gastroparesis or delayed stomach emptying, these muscles don't work properly. They either contact too slowly or don't work at all and, as a result, your stomach doesn't empty properly.
Eating slowly also helps our digestion. Think of digestion as a chain reaction. As soon as we see, smell, or think about food (step 1), we start salivating to prepare for putting that food in our mouth (step 2). Saliva contains enzymes that break the food down, and moistens the mouth for easier swallowing.

P: coughing; C. saliva; B: complement system
OP: coughing: C sneezing: B complement system
OP: complement system: C saliva, B: sneezing
Answer:
P:coughing; C. saliva: B: complement system
Explanation:
The physical, chemical, and biological immune responses are complement system, saliva, and coughing. Therefore, the correct statement is option A.
What is complement system?The complement system is a physical immune response consisting of a group of proteins working together to kill pathogens that enter the body. Saliva is a chemical immune response, which involves secretions, such as sweat, tears, mucus, etc. containing enzymes that can inhibit the growth of pathogens.
Coughing is biological immune response that activates the immune cells such as macrophages and T cells that can recognize and attack pathogens entering the body.
The complement system involves the production of proteins to destroy foreign bodies. Saliva and coughing are chemical and physical responses to expel pathogens from the body, thereby, providing immunity to the body.
Therefore, complement system is identified as physical immune response, saliva as chemical immune response, and coughing as biological immune response.

A type of cellular transport is shown. Which description best identifies this type of cellular transport? Your answer: A.Osmosis, because energy is being used to move molecules with the concentration gradient. B.Active transport, because energy is being used to move molecules against the concentration gradient. C.Facilitated diffusion, because energy is being used to move molecules with the concentration gradient.
Answer:
B. Active Transport
Explanation:
The concentration gradient is from high to low. The molecules are moving from low to high which is against the concentration gradient. Also, the ATP symbol is shown pointing, and ATP is energy.
The description that best identifies the type of cellular transport being depicted in the image would be that of active transport because energy is being used to move molecules against a concentration gradient.
There are basically 2 types of cellular transports:
PassiveActivePassive cellular transports are those that do not require energy in any form. They include osmosis, the movement of water molecules from the region of high to low water potential via a semi-permeable membrane, and simple/facilitated diffusion, the movement of molecules from regions of high concentration to regions of low concentration.
Active transports are those movements of materials in and out of the cell that requires the expedition of energy in the form of ATP. It is usually the movement of materials against their concentration gradients. Examples include vesicle transport, ion pumps, etc.
In the illustration, the direction of movement of the molecules (by the arrow) indicates that it is against the concentration gradient. Also, the burning of ATP gives further credence that is an active system of cellular transportation.

C. an animal that gets energy by eating both plants and other animals
D. an animal that eats only herbs
An herbivore is an animal or organism that gets energy from eating only plants, which is present in option B. Examples are the goat, cow, etc., and they eat the producers, such as the plants.
What is the role of the herbivore?The herbivore is the animal that directly eats the plants of the ecosystem, which are later eaten up by the carnivore, and the herbivore gets more energy than the carnivore as they get energy directly from the plant source. The herbivore only eats plants, and the different ecosystems have different herbivores, such as the land ecosystem, which has the goat, elephant, cow, etc.
