which of the following statements concerning the alternative complement system is true?
Answers
The correct statement concerning the alternative complement system is that it is activated by pathogen surfaces and it doesn't require antibodies.
The complement system is a portion of the immune system that aids in the recognition and destruction of pathogens, such as bacteria and viruses. The alternative complement system is one of the three pathways that activate the complement system. The alternative complement system is activated by pathogen surfaces and it doesn't require antibodies. Rather than that, it employs a series of spontaneous reactions to identify and target pathogens.The other two pathways of the complement system are the classical pathway and the lectin pathway. Unlike the alternative complement system, the classical and lectin pathways are activated by antibodies. The alternative complement pathway plays a critical role in the defense of the host against infection and inflammation, as well as in the clearance of apoptotic cells and immune complexes from the bloodstream.

When the neurotransmitter GABA binds to its receptor's which way does CI chloride move in what is the consequences of GABA binding
Answers
Answer: Cl moves in; GABA is inhibitory
Explanation:
For a neuron to fire, it has to reach what is called a 'threshold' that is more positive than the resting membrane potential. When GABA binds, Cl- flows inside the neuron and hyperpolarizes the membrane, AKA making it more negative. That means when the neuron wants to reach the threshold, it has to make an even bigger jump from its negative state to the more positive threshold. This inhibits the neuron.

which objects on earth absorb photons, what is it reflected as?
Answers
In the photoelectric effect process, photon loses its entire energy to an atomic electron which is in turn released from the atom.
When a photon is absorbed by an electron it itself get destroyed, but it's energy is transferred into the atoms of the object it hit. That energy may re-emitted as a another photon and it happens when light reflects off an object.
Materials like Coal, black paint, and carbon nanotube arrays absorbs light and materials, such as glass , have no absorbing properties and therefore they look transparent. Photon enters the eye get absorbed by one of the rod or cone cells that envelop the retina on the inner back surface of the eye.

A product is sold at a price of $120 per unit and its variable cost is $80 per unit. The fixed expenses of the business are $8,000 per year. Find (i) BEP in $ and units, (ii) profits made when sales are 240 units. Calculate the profit and do a CVP Analysis.
Answers
(i) BEP in $: $8,000
BEP in units: 100 units
(ii) Profits made when sales are 240 units: $4,800
(i) BEP in $ and units:
To find the Break-Even Point (BEP) in dollars, we need to divide the fixed expenses by the contribution margin per unit. The contribution margin per unit is the selling price minus the variable cost per unit.
BEP in $ = Fixed expenses / Contribution margin per unit
BEP in $ = $8,000 / ($120 - $80) = $8,000 / $40 = $8,000
The BEP in dollars is $8,000.
To find the BEP in units, we divide the fixed expenses by the contribution margin ratio.
BEP in units = Fixed expenses / Contribution margin ratio
Contribution margin ratio = Contribution margin per unit / Selling price per unit
Contribution margin ratio = ($120 - $80) / $120 = $40 / $120 = 1/3
BEP in units = $8,000 / (1/3) = $8,000 * 3 = 300 units
The BEP in units is 300 units.
(ii) Profits made when sales are 240 units:
To calculate the profit, we need to subtract the total costs (fixed costs + variable costs) from the total sales.
Variable costs = Variable cost per unit * Number of units sold
Variable costs = $80 * 240 = $19,200
Total costs = Fixed expenses + Variable costs
Total costs = $8,000 + $19,200 = $27,200
Profit = Total sales - Total costs
Profit = (Selling price per unit * Number of units sold) - Total costs
Profit = ($120 * 240) - $27,200
Profit = $28,800 - $27,200
Profit = $1,600
The profit made when sales are 240 units is $1,600.
CVP Analysis:
Cost-Volume-Profit (CVP) analysis is a tool used to analyze the relationship between costs, volume, and profits. It helps in understanding how changes in sales volume affect profitability.
In this case, the CVP analysis can be performed using the given data:
Sales revenue = Selling price per unit * Number of units sold
Sales revenue = $120 * 240 = $28,800
Variable costs = Variable cost per unit * Number of units sold
Variable costs = $80 * 240 = $19,200
Contribution margin = Sales revenue - Variable costs
Contribution margin = $28,800 - $19,200 = $9,600
Contribution margin ratio = Contribution margin / Sales revenue
Contribution margin ratio = $9,600 / $28,800 ≈ 0.3333
Break-Even Point (BEP) in units = Fixed expenses / Contribution margin per unit
BEP in units = $8,000 / $40 = 200 units
Profit = (Selling price per unit * Number of units sold) - Total costs
Profit = ($120 * 240) - ($8,000 + $19,200)
Profit = $28,800 - $27,200
Profit = $1,600
By conducting a CVP analysis, we can determine the Break-Even Point, contribution margin, and analyze the profitability based on the given data.

Lanugo is called downy hair similar to peach fuzz that grows on the body to counteract the heat loss associated with a lack of insulating subcutaneous fat develops by the end of 16 weeks of the fetus's development.
Some babies have lanugo, which is body hair. The earliest type of hair to emerge from hair follicles is this unpigmented, downy hair. Except for the palms, lips, and bottoms of the feet, it can be found everywhere over a baby's body. Around the fourth or fifth month of pregnancy, most fetuses start to develop lanugo.
On the bodies of human embryos as they develop in the womb, lanugo, a type of fine hair, grows. When vellus hairs take their place, either at birth or soon after, these hairs vanish. Although thicker than lanugo hairs, vellus hairs are also naturally thin and translucent.

Please write 2 to 3 complete sentences to explain why society has been developing different renewable resources in favor of nonrenewable resources in the past few decades.
Answers
Answer: Nonrenewable energy resources, like coal, nuclear, oil, and natural gas, are available in limited supplies. This is usually due to the long time it takes for them to be replenished. Renewable resources are replenished naturally and over relatively short periods of time. Renewable resources are resources that can be produced naturally and nonrenewable resources are resources that cannot be replaced. ... Things like fossil fuels, gas, oil and coal, we would use up those resources long before they could ever be replaced naturally.
Explanation: Yeah
Producing energy from fossil fuels with no greenhouse gas emissions while lowering some forms of air pollution. Increasing energy supply diversity and decreasing reliance on imported fuels.
What are renewable resources?A natural resource that can be replenished to replace the portion used up by usage and consumption is known as a renewable resource, also known as a flow resource.
This replenishment can occur naturally through reproduction or through other recurring processes in a limited amount of time on a human time scale.
One of the main issues with producing renewable energy historically has been that supplies are far more unpredictable than with conventional energy production methods.
The availability of supply is less stable than that produced by fossil fuel facilities due to variations in the amount of sunlight and wind.
It aids in generating energy from fossil fuels without the release of greenhouse gases and reducing some types of air pollution and increasing the variety of energy sources and reducing dependency on imported fuels.
Thus, society has been developing different renewable resources in favor of nonrenewable resources in the past few decades.
