Endosperm regulates seed development and facilitates the transmission of maternal nutrients to the embryo. Therefore, option (D) is correct.
What is endosperm?The endosperm is a type of tissue that develops during fertilization and is found inside the seeds of most angiosperm plants. It gives the embryo the nutrients it needs to grow.
Endosperm is produced when the two sperm nuclei that are contained within a pollen grain make their way into the interior of a female gametophyte.
The endosperm contains carbs, protein, and minor amounts of B vitamins and minerals. These components affect our bodies differently: Bran and fiber inhibit starch digestion, preventing blood sugar increases.

Oxygen enters the bloodstream through diffusion.
False
True
Answer:
True
Explanation:
By the process of diffusion, oxygen is driven by a gradient and crosses into the blood, taken up by the hemoglobin (in the red blood cells), and then transported by circulation to the the rest of the cells in the body.
Answer: True
Explanation:
Which of the following statements is true?
A.
Chemical reactions can only absorb thermal energy.
B.
Chemical reactions can neither absorb thermal energy nor release thermal energy.
C.
Chemical reactions can either absorb thermal energy or release thermal energy.
D.
Chemical reactions can only release thermal energy.
Answer: C. Chemical reaction absorb or release thermal (and sometimes other) energy
Explanation:
Chemical reactions can result in products with more or less chemical energy than the precursors. When products have less chemical energy, the excess is converted to heat (exothermic reaction)
When the products have more chemical energy, heat must be added to make up the difference (Endothermic reaction)
Fireworks are examples of exothermic reactions where the excess is released as thermal, mechanical, and radiant energy. A lit match releases thermal and radiant energy.
Respiration is also an exothermic reaction
C6H12O6 + 6O2 —> 6CO2 + 6H2O + energy
Respiration is the reverse of photosynthesis, an endothermic process. The overall photosynthetic reaction is 6CO2 + 6H2O + energy —> 6C6H12O6 + 6O2
In this case radiant energy drives the reaction.
The reaction 2H2O —> 2H2 + O2 is an endothermic reaction driven by electrical energy.
Many reactions are reversible and if one is endothermic, the reverse is exothermic e.g. 2H2 + O2 —> 2H2O +energy is the reverse of electrolysis of water, or respiration vs photosynthesis.

13) When mRNA is "processed", what are the pieces of mRNA that are cut out and stay in the nucleus?
Introns
Exons
Answer:
Introns
Explanation:
The coding region of the gene is the part of the gene that is transcribed. However, not all of the gene makes the final mRNA. There are sequences called exons and introns in the coding region of the gene.
The pre-mRNA contains transcribed sequences of both the introns and exons. However, the introns are removed from the final mRNA by splicing. The final mRNA that is translated to the protein only contains exons. An illustration is attached to illustrate this.

Solid waste is stored in the colon until it is expelled from the body. This demonstrates that the excretory system working with which of the following systems? A circulatory B digestive C respiratory D muscular
Answer:
b
Explanation:
The solid waste that is stored in the colon until it is expelled from the body is a product of the digestive system, which is responsible for the breakdown and absorption of nutrients from food. Therefore, option (B) is correct.
What is digestive system?The digestive system is a group of organs and structures in the body responsible for the breakdown of food into nutrients that can be absorbed and used by the body. The system includes the mouth, esophagus, stomach, small and large intestines, liver, pancreas, and anus.
The excretory system is responsible for removing waste products, including solid waste, from the body. The colon, which is part of the large intestine, is where water is absorbed from undigested food and the remaining waste is stored until it is eliminated from the body.
The circulatory system is responsible for transporting oxygen and nutrients to cells and removing waste products, but it is not directly involved in the storage or elimination of solid waste.
The respiratory system is responsible for gas exchange and the elimination of carbon dioxide, but it is also not directly involved in the elimination of solid waste. The muscular system is involved in the movement of the body, but it is not directly involved in the storage or elimination of solid waste either.

The motion of objects can be quite complex. The motion of this frog is an example, Suppose that the frog moves from one lily pad to the other in 1 second 1 m Describe the motion of the frog as it makes one round trip between the two lily pads Use the terms speed, velocity, displacement, and distance in your answer
Answer:
The speed of the frog is 1m per second the velocity is he can turn and jump in a different direction in 1 second the distance is 1m and there is no displacement.
( this was not my answer but it’s right. I saw it in the comments)
Explanation:
The speed of the frog is understood to be 1m/sec.and the velocity is that through which a frog can turn and jump in a different direction in 1 sec the distance is 1 m. This returning back to the original position represents no displacement.
What is Displacement?Displacement may be defined as the rate of change in the position of an object. It is a vector quantity and has a direction and magnitude. It is represented as an arrow that points from the starting position to the final position.
Velocity is a vector expression of the displacement that an object or particle undergoes with respect to time. The standard unit of velocity magnitude (also known as speed ) is the meter per second (m/s).
Speed may be defined as the rate of change of position of an object in any direction. It is measured as the ratio of distance to the time in which the distance was covered. It is a scalar quantity as it has only direction and no magnitude.
