How are cell membranes involved in homeostasis?
Answer:
Cell membranes enable organisms to maintain homeostasis by regulating the materials that may enter or leave a cell. Some materials easily cross the cell membrane without the input of energy; other materials require energy input in order to cross through the cell membrane
If you designed your own experiment to prove the law of conservation of matter, what conditions would be required?

A student conducts an experiment where he places a light source below a plant. Over a three week time period he observes the plant's growth. Which of the following would he observe at the end of the three weeks.
Answer:
This question lacks options, the options are:
A). Roots would grow up out of the pot and then down towards the light.
B). The plant stem would grow up and roots would grow down.
C). The plant would start to bend over and grow downwards toward the light.
D). The plant would wilt and die.
The answer is C
Explanation:
This question is describing an experiment conducted to test the effect of LIGHT on plants movement, a phenomenon called PHOTOTROPISM. Phototropism is the response of a plant towards a light source.
According to this experiment, a light source is placed below a plant and observed over a three-week time period. At the end of three weeks, the experimenter will observe that "the plant would start to bend over and grow downwards toward the light" because the plants strictly require light to photosynthesize and grow, hence, it will respond by moving in the direction of the available light source.
The growth and the development of the plant parts towards the stimuli source are called tropism. The plant will bend downwards towards the light source.
What is phototropism?Phototropism is the phenomenon in which the parts of the organisms turns and starts growing in the direction of light sources like the sun or artificial light that acts as the external stimuli.
In the experiment, the light source acts as stimuli for the plant and the plant growth is the response. In the experiment the light source is kept down and acts as a stimulus for the plant, in return, the plant bends over and grows in the downwards direction.
Therefore, option C. plant will bend over and grow downwards.

Thinking about Mendel’s earlier studies, does the gene that determines the shape of a seed have anything to do with the seed color? (Explain your answer and name the law that supports it)
Answer:
Yes.
Explanation:
Yes, the gene that is responsible for the shape of a seed have also affect on the seed color because the dominant allele or gene appears in the shape and physical features of the offspring. Dominant allele is the gene that is responsible for the appearance of physical characteristics of an organism. Mendel's laws of inheritance are the laws which support the above phenomenon.
Yes, the gene determines the shape of a seed and seed color.
What is Phenotype?This is defined as the physical and observable trait of an organism. It is controlled by dominant and recessive allele.
When it is a dominant allele, the characteristics are visible in the organisms. Seed shape and color are physical traits which is why the answer was chosen.

What is the impact of the microbial carrying capacity in the soil with worms?
Answer:
Effect of earthworms on soil
Earthworms need the food and habitat provided by surface residue, and they eat the fungi that become more common in no-till soils. As earthworm populations increase, they pull more and more residue into their burrows, helping to mix organic matter into the soil, improving soil structure and water infiltration.

Describe the causes of Weathering and Erosion here: (image 1 with grass)
Hawaii Coastal Cliffs are amongst the tallest cliffs in the world. What causes their formation? (image 2 with a bunch of water)
Based on the pattern of Erosion seen in these images, describe the causes of their formation. (image 3)
Answer:
(image 1) Weathering breaks down the Earth's surface into smaller pieces. Those pieces are moved in a process called erosion, and deposited somewhere else. Weathering can be caused by wind, water, ice, plants, gravity, and changes in temperature. As waves attack the shore, headlands are eroded, producing steep sea cliffs. The waves vigorously attack the portion of the cliff near sea level where joints, fissures, and softer strata are especially vulnerable. The cliffs are undermined and caves are formed. The three main forces that cause erosion are water, wind, and ice. Water is the main cause of erosion on Earth. Although water may not seem powerful at first, it is one of the most powerful forces on the planet.

those produced from mitosis? *
(1 Point)
A. In mitosis, the daughter cells have a random half of the chromosomes from the parent cell
B. In mitosis, the daughter cells have twice as many chromosomes as the parent cell.
C. In meiosis, the daughter cells have twice as many chromosomes as the parent cell.
D. In meiosis, the daughter cells have a random half of the chromosomes from the parent cell
Answer:
D.) In meiosis, the daughter cells have a random half of the chromosones from the parent cell.
Explanation:
In mitosis, the daughter cells have the same number of chromosomes as the parent cell, while in meiosis, the daughter cells have half the number of chromosomes as the parent. The daughter cells produced by mitosis are identical, whereas the daughter cells produced by meiosis are different because crossing over has occurred.
