Fraternal twins are not genetically identical because one chromosome from each pair randomly passes during meiosis and leads to differences between the siblings. Meiosis involves independent segregation of sex chromosomes.
Meiosis is a type of reductional cell division by which a parent cell produces four daughter (gametes) cells having half the genetic material.
Fraternal twins occur when two egg cells are released by the mother, which are fertilized by a different sperm.
During meiosis, sex chromosomes are separated and segregate in a random manner in daughter (sex) cells.

What is natural selection? Is it similar to survival of the fittest? How are the 2 alike? How are they different?
Answer:
Difference: Survival for the fittest is the survival of species/organisms with genes better suited to the environment and are selected for survival and passed to the next generation while natural selection works by giving species who are better adapted to a given set of environmental conditions an advantage over those that are not as well adapted.
Explanation:
Evolution is the slow/gradual development of human beings from simple life forms into higher forms of life over millions of years ago as stated by Charles Darwin in his book 'The Origin of Species' in 1959. He argues that human beings evolved from simple life forms into higher forms of life through:
1.Mutation - abrupt change in the form of a living organism as dictated by the climate or genetic components of the living thing involved.
2.Natural selection - a process in which the stronger species out compete the weaker ones for resources (Survival for the fittest).
3.Environmental adaptation - follows after the first two, where the surviving species isolate themselves from others as they adapt to the new environment.
What designs the shape and size of all animals that are multi-cellar and have a back-bone
Answer
Environmental pressures

Wind blowing rocks together forming smaller rocks
Answer:
weathering
Explanation:
weathering is the breaking down of the rock,
erosion is the movement of sediment from broken rocks
deposition is the dropping of a sediment in a new place
in your case, I would say weathering because the wind is breaking down the rock and it is the first form of the cycle

Write any two adaptational characteristics of aquatic plants.
Answer:
Three Adaptive features of aquatic plants (hydrophytes) are as follows: a) Underdeveloped conducting tissues (xylem and phloem) are present. b) The plants body covered with waxy substance. c) The stems are long, soft and spongy.
Explanation:
Answer:
Aquatic plants require special adaptations for living submerged in water, or at the water's surface. The most common adaptation is the presence of lightweight internal packing cells, aerenchyma, but floating leaves and finely dissected leaves are also common.

If white wool (W) is dominant over black wool (w), can two sheep with black wool produce an offspring with white wool? Explain your answer.
Answer:
No, the offspring of two black sheep cannot have white wool. Since the black wool allele is recessive, both parents have to be recessive (ww) and so do not carry the dominant white wool allele. The only allele the parents can pass to their offspring is the black allele.

On average, Hepatitis A has an incubation period (the length of time before a person shows illness symptoms) of:
Hepatitis A affects the liver. The incubation period of hepatitis A is around 28 days.
What is an incubation period?An incubation time is a period between the infection and the actual appearance of the symptom. It can be said that the time taken for the hepatitis A virus to show its symptoms like nausea, fever, and abdominal pain after infection is incubation time.
Hepatitis A virus spreads through contaminated food and water and is preventable by vaccines. It takes approximately 28 days for the virus to cause the symptoms of the disease from the time of its infection period.
Therefore, the incubation time of the virus is 28 days.

Explanation:
The three standard sex symbols are the male symbol ♂ and the female symbol ♀, and the hybrid symbol ×. They were first used to denote the effective sex of plants (i.e. sex of individual in a given crossbreed, since most plants are hermaphroditic) by Carl Linnaeus in 1751.
