Two types of plants were tested in a two-week long experiment. Both types of plants were exposed to different amounts of sunlight and measured for growth. Which plant grew the least from the end of Week 1 to the end of Week 2?
Answer:
the one which did not receive much sunlight
Plants will degrade and lose their color in the absence of light. Due to inadequate photosynthesis, the shoots exposed to “limited/no” sunlight were yellow/white in hue.
What is the impact of amounts of sunlight on plant growth?The energy plants require transforming carbon dioxide and water into carbohydrates, and oxygen is provided by sunlight.
Photosynthesis generates carbohydrates to increase crop biomass and sustain vegetative and reproductive growth. Photosynthesis can only take place in the daylight, since it requires sun energy.
As a result of photosynthesis being slowed down by the lack of sunshine, the sprouts were unable to synthesize enough chlorophyll to give them their characteristic green hue.
Therefore, the one which did not receive much sunlight

These are models of a plant cell and an animal cell. How can you use the models to help you describe the cell parts that are different between plant and animal cells? Include how the differences in the structures contribute to the function of the whole animal cell and plant cell..
Answer:
Chloroplasts are what give plants their green color. The second major difference between plant and animal cells is the cell wall. While both plant and animal cells have a cell membrane, on plants have a cell wall.
Plants are a green tint because of chloroplasts. The cell wall is the second key distinction between animal and plant cells. Animal and plant cells both have a cell membrane, but only plants have a cell wall.
What is chloroplasts?Chloroplasts are organelles found in plant cells that use the photosynthetic process to transform light energy into relatively stable chemical energy. They help keep life on Earth going by doing this.
Photosynthesis, the process of converting light energy into sugar and other organic compounds utilized as nourishment by plants or algae, is their responsibility.
They also produce the lipid and amino acid components required for the synthesis of chloroplast membranes.
Chloroplasts, which house the chlorophyll in plants, are where photosynthesis occurs.
Therefore, chloroplasts describe the cell parts that are different between plant and animal cells.

In humans, the hormone testosterone enters cells and binds to specific proteins, which in turn bind to specific sites on the cells' dna. What is the probable action of these proteins?.
Testosterone helps RNA polymerase transcribe certain genes. It is a steroid hormone.
Testosterone and gene expressionTestosterone is a steroid hormone produced in the gonads and secreted by the Leydig cells.
During gene expression, testosterone helps to RNA polymerase, which is a key enzyme that acts during transcription.
During transcription, RNA polymerase sequentially adds nucleotides in order to form a single strand RNA.

Three students are arguing over the correct interpretation of the tree below. Student A insists that pine is the most highly evolved living species because it evolved most recently and is more complex than the other species. Student B says the amoeba is the most highly evolved living species because it is older than the other species. Student C says that no living species is more highly evolved than another because all living species have been evolving for the same amount of time from their common ancestor. Which student is correct
Student C is correct because evolution does not necessarily lead to adaptation. Adaptation is an evolutionary process.
Evolution and adaptationThe term 'evolution' can be defined as the general view of 'descendence with modification', which generally occurs due to natural selection.
Organisms evolve to adapt (adjust) to different challenging environmental conditions.
However, a challenging environment may represent normal conditions for another species.

Where does diffusion take place in the respiratory system?.
Answer:
the alveoli
Explanation:
Gas exchange occurs at the alveoli in the lungs and takes place by diffusion. The alveoli are surrounded by capillaries so oxygen and carbon dioxide diffuse between the air in the alveoli and the blood in the capillaries.
—-------------—---—————————————————-
As the blood moves through the capillaries in the alveoli, oxygen diffuses into it and carbon dioxide diffuses out of it
At the muscles, the opposite occurs as carbon dioxide enters the blood from the muscle while oxygen enters the muscle from the blood.
Capillaries surround the alveoli in the lungs. Both the capillaries and alveoli walls are very thin - just one cell thick. They are made of semi-permeable membranes which allow oxygen and carbon dioxide to pass through them.

After surgical recovery, all rats were injected with TRH, TSH, and thyroxine. After each injection, the O2 consumption was measured and rats were given two weeks of rest before the next injection. How do you expect their O2 consumption to change from baseline (increase, decrease, or no change) when exposed to these different hormones
It is expected for Oxygen consumption to increase after the injections.
How is TRH related to oxygen consumption?TRH stands for Thyrotrprophing-releasing hormone. This hormone has been found to increase oxygen consumption as well as body temperature.
How is TSH related to oxygen consumption?TSH is another hormone known as the Thyroid-stimulating hormone. In general, this hormone has been found to increase oxygen consumption.
How is Thyroxine related to oxygen consumption?This hormone has been found to acutely increase oxygen consumption.

If an organism has an ‘n’ of 32, how many chromosomes are in its somatic cells? How many chromosomes are in its gametes?
[tex]n[/tex] represents the haploid number of an organism. We know that gametes are haploid, therefore there will 32 chromosomes in each gamete. A somatic cell on the other hand is what we know as a body cell, which is a product of mitosis. Mitosis produces diploid cells which is represented by [tex]2n[/tex]. In order to find this value, simply multiply the [tex]n[/tex] value by 2 and you should get 64 chromosomes in each somatic cell.

How did the evolution of photosynthetic organisms lead to changes in the hydrosphere?
Answer:
This cycle of water moving through the atmosphere and the energy changes that accompany it, is what drives weather patterns on earth. ... This water is needed in photosynthesis, the food production process in plants. Transpiration (evaporation of water from the leaf surface) then returns water back to the atmosphereExplanation:
All the water on the surface of the world, including seas and lakes, as well as water above the surface of the globe, including clouds, are collectively referred to as the hydrosphere.
What role of photosynthetic organisms in hydrosphere?During photosynthesis, plants use carbon dioxide from the environment to create the nutritional components of food. In lakes and the ocean, carbon is dissolved in the hydrosphere.
Weather patterns on Earth are governed by the cycle of water passing through the atmosphere and the corresponding changes in energy.
For plants to produce food through photosynthesis, they need this water. Water is then returned to the atmosphere by transpiration, the evaporation of water from the leaf surface.
