Answers
Cells in the visual cortex of the brain that fire selectively in response to specific visual features, such as lines oriented in a particular direction, are called: Orientation selective neuron.
These cells are responsible for coding specific visual features, such as lines or edges with a particular orientation to the vertical plane. They are able to do this by encoding spatial information into a firing pattern as the object of interest moves across the visual field.
These cells have direction-dependent responses, meaning they have a higher firing rate when they are presented with certain orientations. When the orientation of a stimulus is different from the preferred direction, there is a decrease in firing rate.
Experiments have shown that these cells have different preferred orientations, meaning some will preferentially fire in one orientation, and others in another.

A neuron generates and propagates an axon potential along its axon. Then transmits the signal across a synapse by releasing neurotransmitters, which trigger a reaction in another neuron or an effector cell. The signal _____________ the receiving cell.
Answers
The signal "affects" the receiving cell.
When a neuron transmits a signal across a synapse, it releases neurotransmitters into the synaptic cleft. These neurotransmitters then bind to receptors on the surface of the receiving cell, which can be another neuron or an effector cell such as a muscle or gland cell. The binding of neurotransmitters to receptors triggers a series of biochemical reactions in the receiving cell, leading to changes in its membrane potential or cellular activity.
This process ultimately affects the behavior or function of the receiving cell, allowing for the transmission of signals and communication between neurons or between neurons and effector cells in the body.

Evaluate Clara's practices for the prevention of parasite infestation in the following scenario.
Last year, Clara lost thousands of dollars when her sheep herd was infested with tapeworms. She has
always been diligent about keeping the pens clean and ensuring a proper diet. She has also always given
her sheep plenty of freedom by allowing them to wander day and night, and she even protects them from
the hot weather by putting them out to graze in the cooler evening hours. She hopes that this year the
herd will be more fortunate.
Answers
I believe Clara's actions will lessen the parasite infestation. I also believe she might arrange for routine veterinary examinations of the sheep to make sure they are free of any parasites that might infect the entire flock.
Because producers can see the visibly ejected worms whereas they cannot see stomach worms, only their symptoms or eggs, tapeworms frequently cause greater anxiety among sheep and goat farmers than stomach worms (nematodes) (in the feces).
People and animals with spines that have intestines are home to tapeworms, which are flat, ribbon-shaped worms. One of three classes of parasitic worms, they are long, segmented worms from the class Cestoda.
The move-and-dose strategy won't frequently work because many sheep pastures can't produce hay. To control parasites in this situation, prophylactic deworming treatments must be given throughout the season.
Clara's activities will therefore reduce the parasite invasion, I can infer. To ensure that the sheep are free of any parasites that could infect the entire flock, she might arrange for routine veterinarian checks of the animals.

Screens out harmful radiation
Answers
Answer:
Explanation:
With the arrival of warm summer weather, states have started to relax their COVID-19 stay-at-home orders. Excited to spend time with family and friends, people are now planning vacations, with one destination remaining a popular choice for many: the beach. However, extra time spent soaking up the sun increases our exposure to harmful ultraviolet (UV) radiation and raises our risk for developing skin cancer.
July is UV Safety Month. We know that one of the best ways to practice UV safety is to wear sunscreen every day. To help you choose and correctly use the best product for your needs, review the nine facts about sunscreen listed below.
Fact #1: Broad Spectrum Sunscreens are Best
UV radiation from the sun includes two types of harmful rays:
Ultraviolet A (UVA) Rays: Most common; cause premature aging of the skin (e.g., wrinkles)
Ultraviolet B (UVB) Rays: Most dangerous; cause sunburns
Overexposure to both types of rays can cause skin cancer. Sunscreens labeled as “broad spectrum” help protect against the effects of both UVA and UVB rays.
Fact #2: Aim for a Sunscreen with at Least 30 SPF
A sunscreen’s sun protection factor (SPF) indicates how much protection the product offers against UV radiation. Sunscreens with an SPF of at least 30 block 97 percent of the sun’s rays.
Fact #3: No Sunscreen is Waterproof or Sweat Proof
Manufacturers can no longer advertise sunscreens as waterproof or sweat proof. Instead, products are now labeled:
Water Resistant: Effective for up to 40 minutes in water
Very Water Resistant: Effective for up to 80 minutes in water
The AAD recommends reapplying sunscreen every two hours, after getting out of the water, or after sweating.
Fact #4: Children Under Six (6) Months Typically Should Not Wear Sunscreen
Infant skin is more sensitive than adult skin. To protect infants younger than six months, the AAD recommends keeping them in the shade as much as possible; dressing them in protective clothing, such as long-sleeved shirts, pants, and a wide-brimmed hat; and making sure they stay hydrated. If you are still concerned about sun exposure, ask your pediatrician if he/she recommends sunscreen.
Fact #5: Sunscreen is Only One Tool in Your UV Safety Toolbox
There are many ways to reduce your exposure to UV radiation. Experts recommend combining sunscreen use with wearing protective clothing, staying in the shade when possible, and avoiding outdoor activities when the sun is most intense.
Fact #6: Use “Teaspoon and Shot Glass Rule” to Determine How Much Sunscreen to Apply
Many people do not apply enough screen. The “Teaspoon and Shot Glass Rule” recommends using one teaspoon of sunscreen to cover the face and neck, and enough sunscreen to fill a shot glass — approximately one ounce — to cover all other exposed areas on the body.
Fact #7: Sunscreen Expires
According to the AAD, the FDA requires all sunscreens to retain their original strength for at least three years. Many sunscreens include an expiration date printed on the label. Visible changes in color or consistency can also indicate that it is time to dispose of the product.
Fact #8: Spray-On Sunscreens Are Convenient, But Not Always Effective
The AAD explains that current FDA regulations on testing and standardization do not apply to spray-on sunscreens. Individuals who want to use spray-on sunscreen should make sure to use an adequate amount, rubbing it in to thoroughly cover all areas of exposed skin.
Fact #9: Sunscreen is Safe to Use
Some recent news stories have called into question the safety of the ingredients used in sunscreens, but sunscreen remains completely safe to use and is recommended by all health care professionals. Read more about this in our blog post titled “Is Sunscreen Safe?”

Around 20 000 toness of municipal solid waste (MSW) is produced at the Vunato Disposal Site in Lautoka per annum.
a) If the organic fraction of MSW is 42.5%, estimate the total volume of biogas (in litres) that may be produced from this feedstock.
b) If the same feedstock is used to generate electricity through a gas turbine - powered power plant where the efficiencies of the gas turbine and the generator are 25% and 80% respectively, what is the total electrical energy that can be generated annually. Compare this energy output with the original energy content of the MSW and comment.
Answers
Total volume of biogas produced from the feedstock would be 68,00,000 litres. Here, it is given that 20,000 tonnes of municipal solid waste (MSW).
And, the organic fraction of MSW is 42.5%.So, the total organic fraction of MSW produced would be:
20,000 × 42.5/100 = 8,500 tonnes
Consequently, the biogas produced from this feedstock would be:
Biogas yield = 0.5 m3/kg of volatile solids degraded
Total volatile solids produced = 8,500 × 0.425 = 3612.5 tonnes
Biogas volume = 0.5 × 3612.5 × 1000 = 18,06,250 m3 ≈ 68,00,000 litres.
Total electrical energy that can be generated annually would be 4.10 × 109 Wh. We have to calculate the total electrical energy that can be generated through a gas turbine-powered power plant where the efficiencies of the gas turbine and the generator are 25% and 80% respectively. The energy content of the organic fraction of the MSW generated is:
E = 22.4 × 106 × 8,500 × 0.425 = 81.5 × 109 Wh
Efficiency of the gas turbine = 25% = 0.25
Efficiency of the generator = 80% = 0.8
Total efficiency = 0.25 × 0.8 = 0.2
Total electrical energy = E × Total efficiency
Total electrical energy = 81.5 × 109 × 0.2 = 16.3 × 109 Wh
= 4.10 × 109 kWh
From this, we can conclude that the total electrical energy that can be generated annually is approximately 20% of the original energy content of MSW. This indicates that there is a significant amount of energy content of MSW that remains untapped, which could be utilized by proper waste management techniques.

How does the body convert a macronutrient into fat? Choose
one.
Answers
Macronutrients are essential to our body and are vital in maintaining a healthy body. Fat is one of the macronutrients that are crucial to our body. It is used by the body to produce energy, regulate body temperature, absorb vitamins, cushion and protect organs, and help in cell growth and hormone synthesis.
Fatty acids in the bloodstream, and ingested fats are carried to fat cells for storage. Fat cells can store fats in the form of triglycerides. A triglyceride is a molecule consisting of three fatty acid chains connected to a glycerol backbone. The conversion of macronutrients into fat happens due to an increase in the production of insulin. When an individual consumes carbohydrates, the body breaks down the carbohydrates into glucose.
The glucose in the bloodstream triggers the production of insulin. When there is a high level of insulin in the bloodstream, it signals the body to store the excess glucose in the cells as glycogen, which can be used as energy at a later time. However, when the body’s glycogen storage capacity is full, the excess glucose gets converted to fat by a process called lipogenesis. Lipogenesis happens in the liver and adipose tissues. The liver converts the glucose into fatty acids, while the adipose tissue stores the excess fatty acids as triglycerides. The stored fat cells can be used as energy when the body is in need of energy.
To conclude, the conversion of macronutrients into fat happens due to the body’s inability to use the excess energy in the form of glucose. The excess glucose gets converted into fats and is stored in the adipose tissues as triglycerides.
