Answer:
Because eggs contain amost all organelles, and materials for growth. A sperm only contains haploid chromosome and certian mitochondria for movement.
Explanation:
:)
The egg, like a sperm cell, has a nucleus with half the number of chromosomes as other body cells. Apart from a sperm cell, the egg contains a large amount of cytoplasm, or cell contents, which is why it is so large.
What are gametes?A gamete is an animal or plant reproductive cell. Female gametes are known as ova or egg cells in animals, while male gametes are known as sperm.
Ova and sperm are haploid cells, with only one copy of each chromosome in each cell. A sperm and an ovum combine during fertilization to form a new diploid organism.
Because the formation of the egg begins before birth inside the developing body of a female embryo and is not completed until the egg is fertilized by a sperm many years later, the egg cell is much larger than the sperm cell.
The sperm cell is small in size because its primary function is to swim to the egg cell.
Thus, the egg cells are large and sperm cells are small.

Describe how the process of natural selection can result in an increase in frequencies of certain traits found in a population.
Answer:
Natural Selection (Answer Below)
Explanation:
Natural Selection is the selection of a more beneficial trait. For example, if trees get covered in soot all the white beetles and butterflys are going to stand out like a sore thumb, but the beetles and butterflies that adapted and evolved now have better traits that help them hide predators. The predators have a harder time finding the now black colored butterflies and beetles due to the black soot meaning the beetles and butterflies will have a higher survivability

Both Sugars and amino acids always contain carbon molecules and both macromolecules can provide energy so are the source of the energy. Sugar molecule more specifically glucose molecule enters glycolysis during the cellular respiration process.
Amino acids always contain the nitrogen molecule in the structure along with carbon, oxygen, and hydrogen, there is a side chain present. Amino acids are the building blocks of the protein, peptide bonds are formed by amino acids together to make a poly peptide chain of a protein molecule.
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.

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.
