Article name: New Research Shows Plants Are Photosynthesizing More in Response to More CO2 in the Atmosphere
BY LAWRENCE BERKELEY NATIONAL LABORATORY DECEMBER 17, 2021
Answers
The article states that research has shown a 20% increase in photosynthetic rate by plants in response to more carbon dioxide in the atmosphere.
What is photosynthetic ?Photosynthesis is the process by which plants, algae, and certain bacteria convert light energy from the sun into chemical energy that can be used to fuel the organisms' activities. This process occurs in the chloroplasts of the cells and involves the conversion of carbon dioxide, water, and light into oxygen and glucose.
The law of the conservation of matter states that matter is neither created nor destroyed, and this process of plants taking carbon dioxide from the atmosphere and converting it into food is an example of this law in action.
The article states that research has shown a 20% increase in photosynthetic rate by plants in response to more carbon dioxide in the atmosphere.
Researchers propose that this increase is a result of plants being able to use more of the carbon dioxide in the atmosphere, as there is more available to them.
To quantify photosynthetic efficiency in the laboratory, researchers use a process called Pulse-Amplitude Modulated (PAM) fluorometry. This method uses a light source to measure the rate of photosynthesis in an individual leaf, and is a way to measure the amount of carbon dioxide taken up by the plant.
To quantify photosynthetic efficiency in the field, researchers use a process called gas exchange measurements. This method uses a chamber that is placed over the plant, and measures the rate of photosynthesis by the amount of carbon dioxide entering and exiting the chamber.

Attached earlobes are a recessive trait in humans in the treee below people with attached earlobes are shaded in which best describes the person labeled x in the tree
Answers
The earlobe-attached individuals in the tree are shaded. Additionally, it is known that humans have a recessive gene for connected earlobes.
A carrier of the attached earlobe gene would be the person with the label x in the tree. A person is said to be homozygous if they have two copies of the same allele of a gene, one from each parent. Heterozygous people are those who have two distinct alleles of a gene (one from each parent).
The person is known as a carrier if a recessive gene is inherited in a heterozygous state. Despite having the recessive gene, the dominant gene prevents them from manifesting the corresponding phenotype.
As a result, a person with attached earlobes may be a homozygous recessive or heterozygous carrier of the gene.
People with attached earlobes are represented by the individuals with shaded boxes in the given tree. Person X's parents would be heterozygous bearers of the trait as none of them have attached earlobes.
Consequently, the connected earlobe gene would also be a heterozygous carrier in person X in the family tree.

Identify 4 factors in the environment (2 abiotic and 2 biotic) that would negatively impact the ability of your organism to survive. Specifically, tell how the organism would respond to these factors.My organism is great white shark
Answers
Great white sharks can be found in both nearshore coastal waters and offshore pelagic waters. Abiotic factors that affect the survival of these organisms are water temperature and salinity. These organisms is well adapted in cold water. The salinity of water is greatly affecting sharks because they should retain sait inside their body. Their cells will rupture that will lead to bloating and death without salt. Biotic factors affecting their survival are the abundance of their prey. If there is overfishing, their prey will decrease in numbers thereby affecting their food supply. Habitat destruction and climate change will also pose severe threats to their survival.

The initial step in vision occurs in the retina, which is a layer of tissue at the back of the eye that contains light-sensitive cells called photoreceptors. When light enters the eye, it is absorbed by the photoreceptors, which convert it into electrical signals. These signals are then transmitted to other cells in the retina, such as ganglion cells, which transmit the signals to the brain via the optic nerve. The visual cortex, which is located in the brain, processes these signals to create the visual images that we see.

b. Describe the journey of a snowflake from when it falls to Earth until the water it contains
becomes groundwater. Include both the movements of the water and the processes involved.
There are many possibilities; limit your answer to one path. (2 points)
Answers
Answer:
When a snowflake falls to Earth, it can land on the ground or on other surfaces, like trees or buildings. If it lands on the ground, it could either melt right away if the temperature is above freezing, join other snowflakes to form a snowpack, or percolate through the snowpack to form groundwater.
If the snowflake becomes part of a snowpack, it will experience periodic melting and refreezing as temperatures fluctuate. Over time, some of the snow will undergo metamorphism and become denser, forming a layer of firn. The weight of the snowpack compacts the layers below and forms glacial ice, which can move down slope due to gravity. This process is called a glacier's ablation zone, where the glacier loses mass.
Eventually, the ice and snow may seep into the ground and become groundwater. Groundwater travels through porous rocks and sediment and can sometimes be drawn up by wells. This journey from snowflake to groundwater involves multiple physical and chemical processes like melting, precipitation, infiltration, evaporation, condensation, metamorphism, and several geological phenomena.

THINK IT THROUGH You may recall that soil is classified by several properties such as color, texture, structure, and pH. Many of the processes that produce soil are related to the activities of living things. Do you think that the types of rocks and minerals found in a particular area could also influence the characteristics of the soil? Explain.
Answers
Answer:
Yes, the types of rocks and minerals found in a particular area can influence the characteristics of the soil. This is because soil formation is a complex process that involves the weathering and breakdown of rocks and minerals over time.
For example, if an area has a high concentration of granite rocks, which are composed of minerals such as quartz, feldspar, and mica, the resulting soil may be sandy or gritty in texture and have a higher pH due to the presence of minerals that do not easily break down. On the other hand, if an area has a high concentration of limestone rocks, which are composed of calcium carbonate, the resulting soil may be alkaline and have a higher fertility due to the presence of easily broken down minerals.
In addition, the type of rocks and minerals in an area can also influence the structure of the soil. For instance, if an area has a high concentration of clay minerals, which are formed from the weathering of silicate rocks such as feldspar and mica, the resulting soil may have a higher water-holding capacity and be more susceptible to compaction.
Therefore, the type of rocks and minerals in an area can have a significant impact on the characteristics of the soil, including its texture, structure, and pH, as well as its fertility and water-holding capacity.

We transformed E coli cells with a plasmid modified to contain a ‘virulence factor’ which would allow growth on media containing the antibiotic kanamycin (Kan). The plasmid confers constitutive resistance to ampicillin (Amp).
Assume you were given competent cells of known transformation efficiency (TE). Assume TE= 1x10[6] (note 10[6] means 10 to the power of 6). You want to have about 1000 colonies on the P-200 plate. How many nanograms of plasmid should you use in the transformation reaction? Select only one answer.
Answers
We need 1 nanogram of plasmid in the transformation reaction when the transformation efficiency is given for 1000 colonies on plate P - 200.
Given the value of transformation efficiency (TE) = \(1 * 10^6\)
Number of colonies on the plate P-200 = 1000
To calculate the amount of plasmid (in nanograms) required for transformation, we need to first calculate the number of cells required for transformation.
To get desired number of cells we multiply the transformation efficiency and number of colonies given such that:
number of cells = \(TE (1*10^6) * 1000 colonies = 1 * 10^9 cells\)
Since 1 nanogram of plasmid is equivalent to \(1 * 10^9\) cells, we can conclude that we need to use 1 nanogram of plasmid in the transformation reaction.

Predict what will happen when a piece of algae (simple plant) from the ocean is placed in a beaker of fresh water. Be sure to include the appropriate vocabulary while you are explaining your answer including the salt and freshwater environments compared to the algae. (Hypertonic, hypotonic, isotonic).
Answers
When an algae from the ocean is placed in fresh water, the water environment around the algae will become hypotonic in comparison to the algae's cytoplasm.
What makes the ocean water hypotonic?The high concentration of salt and other solutes in the ocean water creates a hypertonic environment for the algae, while the low concentration of solutes in the freshwater creates a hypotonic environment.
This change in osmotic pressure will cause water to move into the algae cells, causing the cells to swell. If the water uptake becomes excessive, the cells may burst and the algae may die.
However, if the algae is able to adjust its internal salt concentration, it can survive in freshwater. This process is called osmoregulation.

what is the tonicity of honey
Answers
Answer:
Is honey hypertonic?
Image result for what is tonicity of honey
Honey is 70 to 80% sugar and this high percentage causes hypertonic conditions that may lead to lysis of microbial cell walls.
Explanation:
hope this helps
Honey is hypertonic, meaning it absorbs water quickly. As a result, it can keep a tear dry and draw off the fluid that bacteria require to survive.
What is tonicity?Tonicity is a solution's ability to change the volume of cells by changing their water content. When water enters a cell, it can cause hypotonicity or hypertonicity when it exits the cell.
Hypotonic fluid contains less fluid, sugars, and salt than blood. Hypertonic fluid contains more fluid, sugars, as well as salt than blood.
Isotonic fluid, sugars, and salt concentrations are the same as those found in blood.
Honey is hypertonic, which means it quickly soaks up water. As a result, it can keep a tear dry as well as draw off the fluid required by bacteria to survive.
Honey has such potent antibacterial properties that it can treat severe conditions such as MRSA, which is recognized to be resistant to conventional antibiotics.
Thus, it can be concluded that honey is hypertonic.

The most common reason that introduced species cause trouble is because they are larger than native species. True or False
Answers
The fact that introduced species can result in biological exponential multiplication does not mean that they are a threat to biodiversity.
Biodiversity is defined as the variety of all living things, including various plants, animals, and microorganisms. It is often investigated at three levels: genetic diversity, species diversity, and ecological diversity. We cannot have healthy ecosystems, which we rely on to provide the air we breathe and the food we consume, without a variety of animals, plants, and bacteria. One reason why introduced species are a hazard to biodiversity is that they have the potential to become invasive species that supplant native species and prey on native species, causing unnatural reductions in native species populations. Even if imported species have the potential to multiply biologically exponentially, this does not necessarily entail that they endanger biodiversity.
