Answer:
During the process of meiosis(The process of cell division through which the germ cells such as the reproductive cells are formed), the sex cells produced are haploids (have only 23 chromosomes). This is significant as during the process of fertilization, the nucleus of the sperm (containing 23 chromosomes) and the nucleus of an egg (containing 23 chromosomes too) fuse, hence, retaining the original number of chromosomes in the zygote formed. i.e 46 chromosomes.

Saponification Select one: a. is a hydrolysis reaction. b. results in the production of triglycerides. c. is used to store energy for later use. d. is a reaction found in plant metabolism.
Answer:
A) hydrolysis reaction
Explanation:
hydrolysis can be explained as a chemical process whereby molecules of water is been added to a substance, and in most reaction the substance and the water molecules split to two part as a result of the addition, and there would be gaining bof hydrogen ion by fragment of the parent molecule. An example of this is saponification.
Saponification can be defined as process of converting oil fat as well as lipid to soap and alcohol through heating using aqueous alkali. Common aqueous alkali that can be used is NaOH. Soap are regarded as salt of fatty acid. Reaction between Ethanoic acid and alcohols is an example of a saponification
Here is soap chemical formula
CH3(CH2)14COO− Na+
Answer: The correct option is A ( is a hydrolysis reaction).
Explanation:
Saponification is the alkaline hydrolysis ( using sodium hydroxide or potassium hydroxide) of fats and oil. It is commonly used for making of soaps which are used for washing and cleaning.
The process is a hydrolysis reaction because there is splitting of ester linkage bonds of triglycerides and addition of hydroxyl group from a hydroxide. This process leads to the production of alkaline salts of long chain fatty acids(soaps). This can be summarised below
Triglycerides (fats&oil) + base( NaOH)
-------> Soap + Alcohol

Meditation is a practice of sitting still and quiet for minutes or even hours. It has been practiced for thousands of years and is even a part of religious practices for some people. Carefully controlled, repeated measurements of brain activity have shown that meditation does increase certain chemicals in the brain and even grows the part of the brain that helps people connect with their current surroundings and activities.
Are claims about the effects of meditation most likely scientific or pseudoscientific?
scientific, because people have been claiming for thousands of years that meditation helps them
scientific, because observations of brain growth and chemicals are made carefully and repeatedly
pseudoscientific, because practices that are related to religion are based on beliefs and are subjective
pseudoscientific, because people have made claims about it but scientific observations have not been made

how is the inheritance pattern shown by this flower different from other inheritance patterns you have seen or studied
.Answer: if the image that is supposed to be attached to this question is a picture of a flower showing both red and white spots as it colors, then the inheritance pattern shown is different from the other inheritance pattern because the normal inheritance pattern would only show one color. Normally, a flower would have a uniform color. In this case, only white or only red. The flower shows what we call, co-dominance. Red and white colors are both traits of the flower and the colors both manifest. In other traits, only the dominant trait is exhibited.

Polyculture is well suited to intensive aquaculture because you have two or more non-competing species in the same system
Answer:
True.
Explanation:
It is TRUE that Polyculture is well suited to intensive aquaculture because you have two or more non-competing species in the same system.
This is evident in the fact that Polyculture is a type of agriculture whereby more than one species of plant is cultivated or animals reared simultaneously.
For example, Polyculture in animals may involved paddlefish, tilapia, and bighead carp reared in the same pond. In this case, the paddlefish will feed on crustaceans, while tilapia feed on zooplankton and phytoplankton. Also, bighead carp will feed on zooplankton and big phytoplankton.

The first trophic stage of a food chain, which contains the most energy, is made up of the green plants with in ecosystem known as producers.
What is Trophic level of Food chain?The term "trophic level" refers to an organism's place in the food chain and has a range of one for primary producers to 5 for humans and marine mammals. The mean trophic level of the consumer's prey is multiplied by one to determine the consumer's trophic level.
The trophic levels are divisions into which species in food webs get categorised. These levels can be roughly categorised as producers (first trophic level), consumers, and decomposers (last trophic level). The first trophic level is producers. The first trophic level receives 100% of the energy from the sun, which has the greatest amount of energy, while subsequent trophic levels only receive 10% of the energy of the level before them.
Thus, the first trophic stage of a food chain, which contains the most energy, is made up of the green plants with in ecosystem known as producers.

Why is some amount of air is left inside in your lungs after inhalation
Answer: Residual volume (RV) is the volume of air remaining in the lungs after maximum forceful expiration. In other words, it is the volume of air that cannot be expelled, thus causing the alveoli to remain open at all times. The residual volume remains unchanged regardless of the lung volume at which expiration was started. The residual volume (RV) is the amount of air that is left after expiratory reserve volume is exhaled. The lungs are never completely empty: There is always some air left in the lungs after a maximal exhalation.
So your answer will be Residual volume...
Hope this helps........ Stay safe and have a Merry Christmas!!!!!!!!! :D
It is left because exhaling will never remove all air from your lungs, if it did your body would shut down due to lack of oxygen to all organs. It distributed the atoms throughout the body.
how does the immune lymphatic system help fight against diseases?

A growling stomach and the stimulation of hunger represent the
A
integumentary system and the endocrine system working together.
B
excretory system and the respiratory system working together.
с
digestive system and the nervous system working together.
D
muscular system and the skeletal system working together.
A growling stomach and the stimulation of hunger represent the digestive system and the nervous system working together. The correct option is c.
What is hunger?Hunger is primarily a biologically induced desire for food, which is required for survival.
Hunger can thus be regarded as a quantifiable biological trait of humans that predicts the willingness to eat as well as the amount of food consumed.
During fasting, the stomach secretes the "hunger hormone" ghrelin to promote food intake.
Ghrelin stimulates appetite by activating its receptor GHSR1a in the brain's hunger sensing neurons, and thus represents a promising avenue for the development of anti-obesity treatments.
A growling stomach and the stimulation of hunger represent the digestive and nervous systems collaborating.
Thus, the correct option is C.

6. Name the two ways electric current can be induced using magnetism.
Answer:
Explanation:
We can induce an electric current inside a coil in 2 ways. This is done due to the relative motion of the coil and the magnetic field.
The first and the easier way to do that would be to induce a current on the coil by moving the coil inside a magnetic field.
The second way would be to induce a current on a coil by altering the magnetic field across it.

Suggest what might happen if cells grow and reproduce in an environment where no cholesterol is available.
Cell walls provide support and protection for plant cells and the plasma membrane maintain homeostasis
Explanation:
If cells grow and reproduce in an environment where no cholesterol is available than cell walls provide support and protection for plant cells and the plasma membrane maintain homeostasis.
What is plasma membrane?Cell membrane has been defined as a wall that differentiate and protect the inner structure of the cell from the outer environment. The main function of the cell membrane has to keep away the toxic material out of the cell. The cell membrane contain the channels as well as receptors that gives permission to only selective permeable membrane to enter into the cell.
Cells must maintain homeostasis to survive. To do this cells use various processes. One process keeps the right amount of water inside the cell. A cell takes in the same amount of water as it looses describe that it is maintaining homeostasis by keeping it's water concentration level.
Therefore, If cells grow and reproduce in an environment where no cholesterol is available than cell walls provide support and protection for plant cells and the plasma membrane maintain homeostasis.
