Discuss the adaptations that have enabled flowering plants to overcome the following problems associated with life on land. Be very specific in your description of the adaptations which help angiosperm survive in a land based environment as opposed to an aquatic environment. There are multiple adaptations. Study this before trying to write so that you can include a variety of features. a) The absence of an aquatic environment for reproduction. b) The absence of an aquatic environment to support the plant body c) Dehydration of the plant
Answer:
a) specialized structures and organs for reproduction (flowers)
b) lignin in the xylem
c) waxy cuticle, stomata
Explanation:
a) Angiosperms have flowers, which are specialized reproductive organs. Flowers contain specialized reproductive cells (i.e., pollen cells) which can be dispersed by wind or animals.
b) Plant tissues can be covered by a waxy cuticle that helps to conserve water and tiny pores called 'stomata' in the epidermis that close in order to prevent water loss.
c) Finally, the xylem in land plants provides mechanical support. The cell walls of the xylem are composed of lignin, an organic substance that provides structural rigidity to the plant fibers.
Answer:
A) The absence of an aquatic environment for reproduction.
Pollination. Flowers are developed in order to reproduce, flowers help by attracting animals to pollinate (pollination aids). Pollen for males, seed for females. The seeds are coated with a hard outer layer to protect it. Fruits are made so animals can it them and the seeds will spread by the means of their feces. Seeds can be dormant for a long time.
B) The absence of an aquatic environment to support the plant body.
Roots to help hold to the ground, stems for support, vascular tissue to help hold shape, cell walls more rigid, turgor pressure.
C) Dehydration of the plant.
The cuticle was developed, a waxy outer layer found in the leaves to prevent water from leaving the plant. Stomates control water movement, in trees scales and cork help keep water in. Xylem transports water.

The Sun has a diameter of approximately 1,391,400 kilometers. How big would the Sun be in your scaled-down model of the solar system? Explain how you scaled the Sun’s diameter to fit into your model, and describe how its size compares to the planets.
Answer:
About 100 times more than other planets.
Explanation:
The Sun would be about 100 times bigger than the earth planet in the scaled-down model of the solar system because in the reality the size of sun is 109 times more than the earth so making a model more perfect and nearer to reality we have to maintain the diameter of the sun more than 100 times than the earth and other planets.
Your assignment is to write a first-person story entitled “Life as a Blade of Grass." In your story, you will write an account of your journey through the digestive tract of a farm animal, from the mouth through the colon and out of the body. Your story should start with something like, "I was just standing there minding my own business when a hungry cow approached..."
Answer:One day a cow named Spots woke up. She noticed she was in a desert. She looked around. She saw there was no grass for her to eat, so she went back to sleep. The next day she was hungry, very hungry. All she saw was a cactus and dirt on the ground. The cactus had little spikes. There was only lizards and flies around. She had no food, no water and no friends. Spots was very sad. She got up and started to walk. She walked all day and the next day too. Finally she came to a farm. She wondered where the animals were. All she saw was a husband and wife. They only had cereal with no milk. It was dry. They wished they had milk. Spots asked if she could help by giving them some milk. They said yes and never went hungry again, neither did Spots the cow.

PLEASE HELP///3. Heather had a color blindness test, and she was surprised to discover she suffered from red-green colorblindness. She told her biology teacher, who said, “Your father is color-blind too, right?” How did her teacher know this? Why did her teacher not say the same thing to the color-blind males in the class?
Answer:
In order for a woman to have the colorblind trait, they need to be X^cX^c, meaning that they have to get the trait from both their parents. Males can either have X^cY or X^CY and since Heather has it, it is definitive that her father had X^cY, which means that he is colorblind. Males in her class, on the other hand, can get it from either their mother or father.

To assist in completing this question, you may reference the Animated Technique Video - Gel-Filtration Chromatography. Consider a mixture of four proteins with various molecular weights. A histone molecule weighs 15 kDa, a p53 molecule weighs 53 kDa, an actin molecule weighs 42 kDa, and an IgG molecule weighs 150 kDa. Arrange the molecules in order of their elution from a gel filtration column
Answer:
IgG molecule, p53 molecule, actin molecule, histone molecule
Explanation:
In a Gel-Filtration chromatography, the larger molecules elude faster from the gel than the small ones.
In a Gel-Filtration chromatography, there is a stationary phase and a mobile phase. The stationary phase has beads with pores. Small molecules enter the beads and descend through these beads' pores. On the other hand, large molecules do not enter the beads' pores, so they go down through the mobile phase faster than the small molecules. Since they do not have the obstacle of the pores, they descend between the beads more fluidly. As a result, the larger molecules elute first from the gel than the small molecules.

Explanation:
Study Island
The points at which max potential and max kinetic energy is the last second point away from the boy is max potential and the last point is the max kinetic.
What are max potential and max kinetic energy?The product of an object's mass (m), gravitational acceleration (g), and height is its potential energy (PE) (h). Maximum kinetic energy is the amount of energy present when both the speed and the potential energy are at their highest levels.
The boy is batting the ball and the ball went to the highest point is the max potential energy, then when the ball goes into the distance is called the max kinetic energy.
Therefore, maximum kinetic and potential energy are present at the final point and the mid or in the diagram, the 4th point respectively.

Q1. ____________ is the medium for cellular chemical reactions. *
Nucleus
Cytoplasm
Nucleolus
Golgi complex
Answer:
Functions of cytoplasm
Explanation:
It is the medium for all cellular chemical reactions. It is a medium in which the organelles remain suspended. It helps in the movement of the different cellular elements.
The gel-like fluid found inside cells is called cytoplasm. For chemical reactions, it serves as the medium, hence option B is correct.
What is cytoplasm?It gives the cell's other organelles a base from which to function. The cytoplasm of cell houses all of the processes for cell division, growth, and reproduction.
All cellular chemical processes take place in it as the medium. It's a medium where the organelles are kept in suspension. The various cellular components may move more easily as a result.
The cytoplasm of a cell is where the majority of chemical reactions occur. It is a jelly-like material that the cell membrane encloses.
Therefore, all of the specific function-carrying organelles are contained inside it, and the cytoplasm is where all chemical processes take place.

Cheetahs have become an endangered species due to hunting and loss of their habitat. As a result, there is now very little variation in the traits within their small populations. Which of the following is a result of the limited variation in traits in today’s cheetah population compared to earlier cheetah populations that had greater variation in traits?
A. Cheetahs in current populations are more resistant to new diseases.
B. Cheetahs in current populations have better chances of survival today than they did in the past.
C. Cheetahs in current populations are less likely to become extinct.
D. Cheetahs in current populations are less likely to be able to adapt to environmental changes.
Answer:
Cheetahs in current populations are less likely to be able to adapt to environmental changes
Explanation:
i got the question wrong cuz some1 but im willing to help others this is the correct answer D is the correct answer:)
Cheetahs in current populations are less likely to be able to adapt to environmental changes. Therefore, option (D) is correct.
What is limited variation?Less possible combinations of characteristics indicates a lower level of genetic diversity within the population. Because of this, there may be fewer genetic variations available to supply potentially beneficial characteristics that can aid in the survival of the population. This can have a detrimental impact on the population's ability to adapt to changes in its environment, which can have negative effects.
Because there is less genetic variation in the current population of cheetahs, it is possible that they will have a reduced ability to adjust to changes in their environment, such as the appearance of new diseases, shifts in climate, or the loss of habitat. This might make the possibility of the population going extinct significantly more likely. Hence, the solution that you should select is option D.
