In the earliest stages of development the embryos of a fish, calf, human, and tortoise all look similar. In the next stage the fish looks the most different. What assumption can be made based on this different?

The correct assumption may be that the calf, human and the tortoise are more related to one another as compared to the fishes.

The embryology plays a very important role in determining the common ancestors in the organism. The organisms sharing similar embryological development are more closely related as compared to the others, which do not have the similarity in the embryogenesis. More closely related the organism, the more similar embryonic development would be. Hence, it can be said that the calf, human and the tortoise are closely related to one another as compared to the fishes.

An example of natural selection is the tail of a male peacock. The females of the species choose mates based on the colors of the males’ tail feathers. If females begin using different criteria than feather color when they choose mates, what would most likely happen to the tails of peacocks over time? increased variation in tail feather color because the selection pressure has been relieved increased variation in tail feather color because the peacocks try different ways to impress the females decreased variation in tail feather color because no form of the trait is advantageous decreased variation in tail feather color because the only reason for variation was selection pressure

Answer:

The correct answer is option D, decreased variation in tail feather color because the only reason for variation was selection pressure

Explanation:

According to Charles Darwin, traits that help an individual in selecting mates are favored by the sexual selection while all other normal traits are favored by natural selection.Thus , it is believed that this sexual mating pressure among the male peacocks produce large variation in the color and pattern.The male peacocks compete with each other to attract the female on the basis of their colorful tails and its varied patterns.

4. You and your family are driving through an apple orchard. You notice that the trees in the orchard have both red and yellow ripened apples on the same tree. How is this possible? Explain the process.

This is a possible scenario because plants have the ability to cross-pollinate. Cross pollination is the process in which a flower gets pollinated with pollen from another kind of flower of the same species. Insects, wind, and human intervention can be contributing factors to such phenomenon and it is very common in the farming industry to produce viable produces for consumption.

In a paragraph address these following questions: • How does an underwater earthquake cause a tsunami? • Why do some earthquakes cause more damage than others? the paragraph needs to also include the following things: • discuss how the different types of waves are formed and describe how the waves travel • explain how scientists use waves to track and analyze earthquakes • cover recent events involving earthquakes and/or tsunamis that illustrate the points made in your explanation

What is an Earthquake

Earthquakes are vibrations in the earth's crust They occur along all plate boundaries but are more destructive usually at destructive plate boundaries

How are they measured

The magnitude or size of an earthquake can be measured by an instrument called a seisometer and are shown on a seismograph. The earthquakes are measured on the Richter scale from a value of 1 to 10. Each level of magnitude is 10 times more powerful than the previous. Therefore a level 7 is 100 time more powerful than a level 5.

Why do some earthquakes cause more damage than others?

Some earthquakes take place in rural areas where few people live and little is damaged

If they occur near large urban areas with many people, transport services, large buildings and services such as gas and electricity - there can be a great amount of deaths and damage

In Poor countries - LEDC's they have poorly built buildings, few emergency facilities, and the equipment to help rescue people - a good term to use is that they have a poor infrastructure.

In rich countries - MEDC's such as the USA they prepare for an earthquake with drills and have a great deal of trained emergency personnel and equipment to go to help the injured. They also try to build to withstand earthquake damage - ie The Transamerica building

The time of day can be important - If the earthquake hits when it is the rush hour or when there is a large number of people located in a certain area - this can cause a great loss of life

Obviously if they occur near to coasts then Tsunamis can cause a great deal of damage and deaths such as the 2004 Boxing Day Tsunami

Ans.

Plant hormones are signalling molecules, produced b plants that regulate growth, development and other cellular processes of plants. There are five types of plant hormones, which include abscisic acid, auxins, cytokinins, ethylene, and gibberallins.

Given chart represents relationship between different plant hormones and their responses or functions. Auxin promotes plant growth, plays role in tropism, abscisic acid plays role in seed and bud dormancy, cytokinin promotes cell division, ethylene controls plant growth and stimulates flowering, and gibberallins cause stem elongation.

Basically, when we say alternation of generations, this refers to the life cycle of other Eukaryotes, particularly plants. What happens is that the alternation happens in between their haploid and diploid stages. Therefore, the statement that accurately describes what this means is the second option.

Which of the following best compares the male and female reproductive structures of a gymnosperm? A Gymnosperms produce flowers, and the male stamens produce pollen that fertilizes the egg inside the female ovule. B Gymnosperms produce male cones and female cones, and the pollen from a male cone fertilizes the egg inside a female cone. C Gymnosperms have male sporangia and female archegonia, and spores fertilize eggs contained inside the embryo sac to form zygotes. D Gymnosperms exist as male and female gametophytes, and the male plant produces spores that fertilize eggs inside the female archegonia.

Answer: B Gymnosperms produce male cones and female cones, and the pollen from a male cone fertilizes the egg inside a female cone.  

Gymnosperms are terrestrial plants, which lacks flowers. The ovule or seeds are remains naked in hard woody structures called as cones. In the gymnosperms the green sporophyte generates cones that contains male and female gametophytes. A male cone consists of microsporophylls where male gametophyte also called as pollen are produced and released into the wind. The wind act as a agent for pollinating the female gametophyte present in the female cone.  Inside the female cone the megaspore mother cell produces four haploid megaspores, one megaspore divide itself to form the female gametopyte. The fusion of the pollen with the female gametophyte produces diploid zygote, which later on divides to form the embryo.
