Answer:
The correct answer is "A fish population in which the average skin brightness decreases over several generations in the presence of predators"
Explanation:
In biology, an adaptation is defined as an evolutionary response at which a group of organism develop new traits or behaviors as result of new environmental conditions. In this case, a fish population which skin brightness decreases over several generations in the presence of predators is an example of an adaptation. The fish decreasing its bright skin is the new trait developed as a result of the presence of predators, and as stated, adaptation occurs over several generations not within one generation.
Answer:
Because they are the most destruction waves
Explanation:
Surface waves travel just below the earth’s surface. Examples of surface waves are Rayleighs and Long waves. Rayleighs cause ripples on the ground while long waves move the ground horizontally perpendicular to the direction of travel of the wave. Therefore, these waves are capable of destroying the foundations of structures and hence causing their collapse. Studying these waves allow these professionals to design foundations strong enough to withstand these waves.
Ans.
In human body, three types of blood cells are present, which include red blood cells, platelets, and white blood cells. Although these cells are started out alike, they show different shapes, sizes, and functions due to instructions that differentiate them into different types. These instructions are given by particular chromosomes present in the cells as the chromosomes consist of DNA that provides information to the cells, which is responsible for characteristic behavior of that cell.
Hence, the correct answer for the blank is 'B) chromosomes.'
Answer:
The correct answer would be D) Kittens receive features from both parents but the plant offspring receives features from a single parent.
Cat only reproduces sexually in which male and female parent contribute equal genetic material to the offspring. It leads to the genetic variation in the offspring.
In addition, crossing over takes place during gametogenesis also adds to the genetic variation of the offspring produced by sexual reproduction.
This is the reason that kitten (offspring produced by sexual reproduction) has some genetic variations as compared to the parent and it does not resemble either of the parents.
In contrast, saplings can be done vegetatively through cutting due to saplings receive genetic material from a single parent.
Answer:
E. Mangroves have only one type of root system
Explanation:
Mangrove species are those species of plants found in a saline environment. The soil they are found is usually shallow and swampy (water-logged). They possess characteristics feature that helps them adapt and survie in their habitat.
One of those features is the possession of PNEUMATOPHORES OR BREATHING ROOTS, which is a kind of root system that extends out so that the pores on them can allow the intake of gases directly from the atmosphere.
