Products enter a reaction and reactants come out of a reaction true or false?

Answers

Answer:

[tex]\boxed {\boxed {\sf False }}[/tex]

Explanation:

In a chemical reaction, the products are produced. The reactants are the substances that react.

In a chemical reaction equation (with the arrow pointing right) the reactants are on the left and the products on the right.

[tex]reactants \rightarrow products[/tex]

The reactants enter and the products come out.

So, the statement given - products enter a reaction and reactants come out - is false and it is actually the other way around.

Answer:

C. An object at rest remains at rest and an object in motion remains in motion at a constant speed and in a straight line, unless acted upon by an unbalanced force.

Explanation:

In essence, Newton's first law of motion states that an object at rest won't move unless an outside force causes it to move. Similarly, an object moving at a constant speed will continue moving at that same speed indefinitely, unless an outside force causes it to change speed.

HELLPP! ITS BIOLOGY

Answers

Answer:

So that in a guinea pig cross in the offspring the recessive trait —long hair— can be observed in 25%, the most probable genotype of the parents is heterozygous Ss.

Explanation:

In guinea pigs, for the characteristic hair length, short hair is the dominant allele and long hair is the recessive one.

In order for 25% of the offspring to express the recessive characteristic, the parents must have a recessive genotype, which can be seen in Punnett's Square:

P: Ss X Ss

Alleles     S     s

S             SS   Ss

s             Ss    ss

Where the offspring is:

50% Ss with short hair phenotype 25% SS with short hair phenotype 25% ss whose phenotype would be long hair.

According to this, heterozygous parents for the characteristic long hair in guinea pigs have a 25% chance of having offspring with long hair.

Which of the following is true regarding glycolysis ?
Choose 1 answer.
A.) It requires glucose as a reactant.
B.) It produces 36 ATP.
C.) It occurs in the mitochondria.
D.) It is an aerobic process. ​

Answers

Answer:

I would have to say A

Explanation:

Glycolysis is the first step in the breakdown of glucose to extract energy for cellular metabolism. So we already know that it uses glucose because thats what its breaking down. Glycosis produces 2 ATP so B is wrong. Glycolysis happens in the cytoplasm so C is wrong. Finnaly aerobic is using free oxygen in the process of the reaction. However glycolysis uses no oxygen and is  anaerobic.

Glycolysis requires glucose as a reactant.  

Glycolysis refers to a cytoplasmic pathway that dissociates glucose into the three-carbon compound and produces energy in the form of ATP.  

• The process of glycolysis takes place in the cytoplasm.  

• In the process, the net production of 2 ATPs takes place.  

• It can be both anaerobic and aerobic process.  

• The process of glycolysis completes in 10 steps, five of which are in the preparatory phase and the rest 5 are in the pay-off phase.  

• The process of glycolysis is used by all the cells of the body to produce energy, and the final product of glycolysis is pyruvate.  

Thus, correct answer is option A, that is, it requires glucose as a reactant.

Genetic Problems

Explanation:

When people genetically modify animals, they can mess up a lot of their natural abilities. For example in some cases scientist have made cows who produce more milk, but couldn't reproduce anymore because of it. Sometimes it even hurts the animal. People have bred dogs in certain ways that makes it hard for them to breathe, like Bull dogs who has respiratory issues. This makes decreases their life span and continuing to bred them will only make it worse. When scientist have a certain trait they want they also make animals breed with their own families. Incest creates a lot of genetic problems.

What are angiosperms?

Angiosperms, that are also known as flowering plants, have “seeds” that are sealed off within an “ovary”, while gymnosperms do not have fruits or flowers and have uncovered seeds on the surface of leaves. Seeds of gymnosperms are often arranged as “cones”.

The features and characteristics that distinguish angiosperms from gymnosperms are fruits, flowers, and “endosperm” in the seeds. Examples of “Angiosperms” are “monocots” like orchids, lilies, agaves, grasses and dicots like, peas, roses, sunflowers, maples and oaks. “Gymnosperm” examples include “non-flowering evergreen” trees like pine, fir and spruce.

We are used to fighting in the summer. Thats when the lands to our north thaw enough for the Vikings to venture south to our lands hoping to steal our livestock and crops. Our walls, however, protect our farms. As the Norsemen try to come ashore, we fight them back with ease. Our arrows, bolts, and rock are more than enough to fend them off as they attempt to land on our beaches. They may not have what is ours, and soon they turn toward other coasts and other forts as ours are too strong for them.Then come the Britons from the south. The Britons claim to this land is admittedly greater than ours. They were here before the Romans and will probably outlast our Saxon rule, but that does not matter today. Today this land belongs to Ida the Saxon king, and we will hold it for him and his heirs. Their numbers cannot stand against our fortifications. Our steel is superior to theirs, as our swords and spears cut through their armor with ease. We have the higher ground, for Bamburg stands on a dolerite outcrop. Not only do we use the rock as our foundation, we have cut into the earth and used it to build our walls, and we launch our rocks toward our enemy as they attempt to storm the hill. With these rocks and our arrows and bolts, we cut half their army down before they even reach our battlements. Their spirit weakens as their forces are cut down, as we easily strike down those foolish enough not to break ranks and run. No man can defeat us once we lock ourselves behind these walls. We have plenty of land and cattle here. We can outlast any siege. Thanks to Lord Ida of Bernecia, we are protected.Lord Ida had us build this stronghold high above the shore, and we are invincible from attacks by land and sea, but now we must deal with airborne enemies as well.The dragons have come out of the East somewhere and bring with them fire. They attack when the sun is high. They know our bows and crossbows are worthless against them, as our arrows and bolts bounce off their thick hide. They swoop down and take our sheep in their claws and maws, returning to whereever they came from before dusk with a fifth of our provisions. The fire drives our bravest men inside as we cower with the women and children, hoping to avoid the death that the dragons bring.Aston, the ironsmith, and his fisherman brother, Aethel, claim to have a solution. They have combined their tools and designed a contraption that might bring the winged monsters out of the sky. Fishing nets with iron barbs launched from paired ballistae. The ballista is a giant crossbow left from the Roman invasions. The contraptions take three men to crank, and aiming the ballistae pairs has proven difficult, but we hope to fight when they return tomorrow.Nets are weighted down with iron spikes. As we launch the projectiles at the dragons, we hope to drop them into the sea, or at least pin them to the ground where our swords and spears can do harm. Aethel believes that dragons falling into the water will surely drown, and Aston believes that we should attack the wings of the grounded dragons so that they cannot escape our mighty warriors. But that lesson is for tomorrow when the dragons return at high noon. Tonight we plan our attack and hope our weapons prove their design.Based on the information found in the passage, which invaders attack the Saxons by land?A the VikingsB the dragonsC the BritonsD the Romans
