Înlănțuirile de reflexe condiționate într-o anumită ordine sunt instincte ca apărarea fată de foc. Substanța cenusie formeaza în creierul mare scoarta cerebeloasă.
Answer:
False.
True.
True.
Explanation:
Voluntary reflexes close in the spinal cord. (False).
Chains of reflexes conditioned in a certain order are instincts like defense against fire. (True)
The gray matter forms the cerebellar cortex in the large brain. (True)
Voluntary actions are done with consciousness and controlled by the brain, while reflex actions are done with unconsciousness and controlled by spinal cord. Reflex actions are the sudden actions taken by the spinal cord instead of brain because this action is performed quickly in order to avoid the damage.
The following four ears of corn were taken from separate plants. Each kernel represents an offspring. The kernels on the four ears were counted for the color trait (purple or white) and/or sweetness trait (starchy or sweet). The data gave these phenotypic ratios for the four ears:
Ear #1 – 3 purple : 1 white
Ear #2 – 3 starchy : 1 sweet
Ear #3 – 9 purple, starchy : 3 purple, sweet : 3 white, starchy : 1 white, sweet
Ear #4 – 1 purple : 1 white
Which traits are recessive?
Answer:
the answer is white and sweet, i just took the quiz
Explanation:
The phenotypic ratio provides information about how many genes are involved in the cross, which is the dominant trait and which is the recessive trait. In the exposed example, white and sweet are the recessive traits.
-------------------------------
By looking at the phenotypic ratio of the progeny, you can tell which trait is the dominant one and which is recessive.
Let us assume two diallelic genes, each coding for one trait.
Let us also say that these genes assort independently -they are not linked-, and they do not interact with each other.
When we are only considering one single gene,
the phenotypic ratio after crossing two heter0zyg0us individuals is 3:1. In these situations, we expect to see 3/4 of individuals expressing the dominant trait, and 1/4 expressing the recessive trait.the phenotypic ratio after crossing a heter0zyg0us individual with an h0m0zyg0us recessive one is 1:1. We expect to see 2/4 of the progeny expressing the dominant trait and 2/4 the recessive trait.When we are only considering two genes simultaneously, we expect to find the following phenotypic ratio 9:3:3:1
9/16 individuals expressing both dominant traits3/16 individuals expressing one dominant trait and one recessive trait1/16 individuals expressing both recessive traits.
Now let us analyze each Ear,
Ear #1 – 3 purple : 1 white
Only the color trait is considered. The phenotypic ratio is 3:1Two heter0zyg0us individuals must be involved in the cross3/4 are purple and 1/4 is whiteDominant trait: purpleRecessive trait: white
Ear #2 – 3 starchy : 1 sweet
Only the sweetness trait is considered. The phenotypic ratio is 3:1Two heter0zyg0us individuals must be involved in the cross3/4 are starchy and 1/4 is sweetDominant trait: starchyRecessive trait: sweetEar #3 – 9 purple, starchy : 3 purple, sweet : 3 white, starchy : 1 white, sweet
Both traits are considered. The phenotypic ratio is 9:3:3:1Two dihybrid individuals must be involved in the cross9/16 are purple and starchy, 3/16 are purple and sweet, 3/16 are white and starchy, and 1/16 is white and sweetDominant trait: purple and starchyRecessive trait: white and sweetEar #4 – 1 purple : 1 white
Only the color trait is considered. The phenotypic ratio is 1:1One heter0zyg0us individual and one h0m0zygous recessive individual must be involved in the cross2/4 are purple and 2/4 are whiteDominant trait: PurpleRecessive trait: WhiteThe recessive traits are white color and sweet taste.

How does static electricity work?
Answer:
"Static electricity is the result of an imbalance between negative and positive charges in an object. These charges can build up on the surface of an object until they find a way to be released or discharged. One way to discharge them is through a circuit. ... Remember, objects with the same charge repel each other." ~ www.loc.gov
Essentially saying that if you have a lot of friction, it will create a positive and negative electric charge, this electric charge also contains a small magnetic field which is static electricity.

Short tails in cats are recessive to long tails.
7. TT
8. Tt
9. It
Answer:
4. Brown
5. Brown
6. Blue
7. Long
8. Long
9. Short
Explanation:
Dominant alleles are always expressed when they are present. Recessive alleles are masked by dominant alleles.
Therefore, two copies of a recessive allele are required to show the recessive trait. Either one or two copies of a dominant allele produces the dominant trait.
Therefore, for dominant brown eyes, BB or Bb gives brown eyes, bb gives blue eyes.
For recessive long tails, tt gives short tails, TT and Tt gibe long tails
If free ear lobes ( L ) are dominant over attached ear lobes ( l ) what is the phenotype of an individual with a genotype of l l ?
a. attached ear lobes
b. Free ear lobes
c. L L
d. One ear lobe attached, one ear lobe free
Answer:
An individual with an ll genotype (recessive) for the ear lobe shape trait will have a phenotype of attached ear lobes (option a).
Explanation:
The phenotypic expression of a recessive trait only occurs when both members of the allelic pair are recessive, while the presence of at least one dominant allele inhibits the expression of the recessive trait.
In this case, for the "ear lobe shape" trait, an individual with a genotype ll has a phenotype of attached ear lobes, which is recessive. In contrast, LL and Ll genotypes would express a free ear lobes phenotype.

What would happen to the concentrations of ATP, NADPH and Sugars if PSII stopped working?
ATP - decrease, stay the same, increase
NADPH - decrease, stay the same, increase
sugars - decrease, stay the same, increase
Answer:
1. ATP - decrease
2.NADPH - decrease
3. sugars - decrease
Explanation:
Photosynthesis is a type of biosynthesis that produces glucose from the reactants: sunlight, carbon dioxide, and water. It occurs in the chloroplast in two phases, the light-dependent, and light-independent/dark reactions where sugars are made. Pigments like chlorophyll absorb light energy at specific wavelengths in the light reaction which activates photosystems
Here:
chlorophyll forms photosystems (PS I & PSII) with proteins called a complexPS II absorbs and transfers light energy to the reaction core. a water molecule is split apart to form an electron, H+ and oxygenElectrons are shifted to photosystem I from photosystem II. ATP and inorganic phosphate are synthesized from ADP. H+ is added to NADP to form NADPHThe NADPH is integral to the Calvin Cycle, as part of the light independent reactions- these synthesize sugar molecules.
If PS II no longer works, there will be less ATP, NADPH, and no sugars produced.
What would happen to the concentrations of ATP, NADPH and Sugars if Photosystem II (PSII) stopped working is a: decrease.
During photosynthesis, the primary acceptor of carbon are Photosystem I (PSI) and Photosystem II (PSII) because it occurs in a light-dependent reaction.
Photosystem II (P680) is a large membrane protein complex which serves as a primary acceptor of carbon during a light-dependent reaction.
However, the following would happen when the Photosystem II (P680) stops working:
A decrease in the concentrations of ATP.A decrease in the concentrations of NADPH.A decrease in the concentrations of Sugars.Read more: https://brainly.com/question/12827458
As the average kinetic energy of the particles in a gas increases, which of the following
occurs? (1 point)
The temperature of the gas increases.
The temperature of the gas decreases.
The number of particles increases.
The number of particles decreases.
Answer:
Amontons’s law. If the temperature is increased, the average speed and kinetic energy of the gas molecules increase. If the volume is held constant, the increased speed of the gas molecules results in more frequent and more forceful collisions with the walls of the container, therefore increasing the pressure
Discuss some of the advantages to having a cycle that partially replenishes itself. In the Calvin cycle, what would happen to the cycle if there was no carbon dioxide available?
Answer:
The carbon atoms used to build carbohydrate molecules come from carbon dioxide, the gas that we exhale with each breath.
Explanation:
Dark reactions are also referred as "light independent reactions" (since they can occur during day or night) or as "carbon-fixation" (since carbon dioxide is taken from the air and carbon is affixed to compounds in the plant) or as the Calvin Cycle (named for the person who discovered it).

I need to know everything about the 13th element
Facts:
Aluminum is the 13th element in the Periodic Table and one of Earth's most abundant metals, and so is aluminum. Each atom of aluminum contains 18 protons. Aluminum atoms with fewer than 18 electrons are cations, while those with more than 18 electrons are anions.In 1884, the cap of the Washington Monument was made using aluminum because the metal was so highly valued at that time.Only 5% of the energy needed to purify aluminum from alumina is required to recycle aluminum from scrap. In fact, you can even recycle the element at home, if you like.
When a substance is added to meat, amino acids are produced.
What is this substance?
A) a hormone
B) an enzyme
C) an oil
D) water
The answer is B an enzyme ！
Answer:
[tex]\boxed {\boxed {\sf Enzymes}}[/tex]
Explanation:
Meat is a good source of protein because it is the main component. Hormones, oil, and water won't really produce a substance when added to meat. Enzymes break down different substances. The right enzyme can break down proteins. The monomer, or building block, of protein is an amino acid. Therefore, when a protein is broken down, amino acids are produces.
So, from the information above, we can assume that the substance is an enzyme. Enzymes break down meat/protein into amino acids.

Viruses are able to invade cells after first attaching to their Cell membrane.
What are viruses?A virus is an infectious microorganism made up of a protein-coated segment of nucleic acid (either DNA or RNA). A virus can't multiply by itself; it has to infect cells in order to utilise the host cell's components to make copies of itself.
A virus frequently causes harm to the host organism by killing the host cell in the process. AIDS, COVID-19, measles, and smallpox are well-known examples of viruses that cause human disease.
Viruses can infect people. But in reality, viruses infect a wide variety of organisms. For example, there are viruses that infect fungi and viruses that infect bacteria.

Can carbon atoms bond with other atoms to form long chains?
Answer:
yes
Explanation:
Answer:
The Uniqueness of Carbon
Because each carbon is identical, they all have four valence electrons, so they can easily bond with other carbon atoms to form long chains or rings. In fact, a carbon atom can bond with another carbon atom two or three times to make double and triple covalent bonds between two carbon atoms.
