The graph shows the change in a fish population over time. During this same
time, the algae population increased.
Which statement best explains the data?
O A. The pond was too small for the original fish population.
O B. The fish got sick from eating the algae.
O C. The pond experienced an aiyal bloom.
O D. The algae poisoned the pond.
Answer:
C. The pond experienced an algae bloom.
Explanation:
From the graph we see that the fish population continue to decrease with time. As time passed on, the fish population keeps suffering a decline. In retrospect, the population of the algae continued to increase.
We can ascribe this to the pond experiencing an algae bloom. It could be due to condition called eutrophication. When nutrients become very much in water and more algae is produced. This leads to dissolve oxygen amount reducing in the water body. Therefore, fishes will die off.Answer: c pond experienced a algae bloom

During cellular respiration, cells convert the energy stored in glucose to make the energy molecule ATP, as shown in the equation. Less than 40% of the energy found in glucose is actually converted into ATP. What happens to the other 60% of this energy
Answer:
the other 60% of energy is stored away for further use in the cell
Explanation:
i hope im right
In the cell from glucose, 40% of energy is utilised to make ATP and the rest 60% is used in the process of making ATP. So 100% of glucose cannot be converted into ATP.
How does ATP form from glucose?Glucose is a major source of energy. It has carbon, oxygen, and hydrogen . Due to the presence of oxygen, it can easily break down to produce energy during times of need.
Glucose is broken down into pyruvate by the process of glycolysis. In this process, the net gain is 2 ATP. Pyruvate converts into acetyl CoA. ATP is required in this process. Acetyl CoA enters the Krebs cycle.
To enter the mitochondria, ATP is required. Acetyl CoA enters the krebs cycle and electron transport chain. The FADH₂ , NADH are broken. Proton gradient is formed due to the electron movement. Then ATP is formed due to the proton gradient across the inner mitochondrial membrane . To make ATP a lots of ATP have used in the process. So net gain of ATP of a glucose is 40% as rest 60% has used in the process .
Hence, 40% of energy of glucose make ATP, and the rest 60% is used in the process of making ATP.

Explanation:
The innate immune response is the first mechanism for host defense found in all multicellular organisms. The innate immune system is more ancient than the acquired or adaptive immune response, and it has developed and evolved to protect the host from the surrounding environment in which a variety of toxins and infectious agents including bacteria, fungi, viruses and parasites are found (1).
The immune system is complex and is divided in two categories: i) the innate or nonspecific immunity, which consists of the activation and participation of preexistent mechanisms including the natural barriers (skin and mucosa) and secretions; and ii) the adaptive or specific immunity, which is targeted against a previously recognized specific microorganism or antigen. Thus, when a given pathogen is new to the host, it is initially recognized by the innate immune system and then the adaptive immune response is activated (2). Innate immunity is the host’s first line of defense and is intended to prevent infection and attack the invading pathogens.This nonspecific mechanism is fast (minutes to hours) while the adaptive response takes longer (days to weeks).
Innate immunity is comprised of different components including physical barriers (tight junctions in the skin, epithelial and mucous membrane surfaces, mucus itself); anatomical barriers; epithelial and phagocytic cell enzymes (i.e., lysozyme), phagocytes (i.e., neutrophils, monocytes, macrophages), inflammation-related serum proteins (e.g., complement, C-reactive protein, lectins such as mannose-binding lectin, and ficolins); surface and phagocyte granule antimicrobial peptides (e.g., defensins, cathelicidin, etc.); cell receptors that sense microorganisms and signal a defensive response (e.g., Toll-like receptors); and cells that release cytokines and inflammatory mediators (i.e., macrophages, mast cells, natural-killer cells). Once the interaction host-invader pathogen enters, a signaling cascade is initiated which enhances the immune response and activates specific mechanisms (3-5). This natural immune response is designed to: a) prevent infection, b) eliminate invader pathogens, and c) stimulate the acquired immune response.
The correct examples of physical, chemical, and biological barriers are coughing, saliva, and complement system respectively.
What do you mean by Barriers?Barriers may be defined as something that blocks the free passage of any object, compound, or thing.
Coughing mediates the physical barrier that kills the pathogen and improves the body's immune system at the physical level. Saliva consists of an enzyme that kills the pathogens on body surfaces, so it is classified under a chemical barrier. Biological barriers involve the action of the complement system which performs the activity of lysis of pathogen particle and stimulate the body's immune response.
Therefore, the correct examples of physical, chemical, and biological barriers are coughing, saliva, and complement system respectively.

Challenge: In the process of photosynthesis, plants use carbon dioxide (CO2), water (H2O), and light energy to produce a sugar (C6H12O6) and oxygen (O2). In the process of aerobic respiration, animals and plants release energy from sugar and oxygen and produce carbon dioxide and water. The chemical equations that describe these reactions look like this:
6CO2 + 6H2O + light C6H12O6 + 6O2
C6H12O6 + 6O2 6CO2 + 6H2O + energy
How do these equations explain why the total amount of O2 and CO2 remains the same?
Answer:
Picture below
Explanation:
hope it helps
The total amount of O₂ and CO₂ remains the same because their 6 molecules of carbon formed glucose and the remaining 6 molecules of oxygen are released as by-products.
What is the difference between respiration and photosynthesis?Green plants make their own food through a process called photosynthesis, which transforms light energy into chemical energy.
Living things use the process of respiration to change oxygen and glucose into carbon dioxide and water, which releases a significant quantity of energy.
There are two stages to photosynthesis: light reaction and dark reaction. Inhalation and exhalation are the two phases of respiration. Because photosynthesis depends on light, it only occurs during the day. No organism can survive without breathing, which is a constant activity.

It is known that complex carbohydrates provide more sustained energy over time than simple sugars such as sucrose. Complex carbohydrates are polysaccharides, which are long chains of smaller sugar molecules bonded together. Simple sugars are monosaccharides that contain only one molecule.
Why do complex carbohydrates provide more energy over time versus simple carbohydrates?
Answer:
Complex carbohydrates contain longer chains of sugar molecules than simple carbohydrates. The body converts these sugar molecules into glucose, which it uses for energy. As complex carbohydrates have longer chains, they take longer to break down and provide more lasting energy in the body than simple carbohydrates
Explanation:
Answer:
A.) Complex carbohydrates have more chemical bonds to break than simple sugars, which takes longer for the body to digest and provides more units of energy for the body to use.

Answer:
c-The water is under pressure naturally and no pump is needed.
Explanation:
Water from Artesian well is the water is under pressure naturally and no pump is needed.
What is Artesian well?A well from which water flows under natural pressure without the need for pumping is known as an artesian well.
It is excavated or drilled whenever a gently sinking, permeable rock layer (such as sandstone) collects water at a level higher than the ground surface at the well site.
Water goes down into the aquifer (water-bearing layer) at the outcrop, but is blocked from escaping by impermeable rock layers above and below it (such as shale).
Water is forced to the surface of a well drilled down into the aquifer by the weight of the water (hydrostatic pressure) the pressure for the continuous up flow is maintained by the continued penetration of water into the aquifer at the intake region.
The ability to collect water is what distinguishes artesian wells.
The water is under pressure naturally and no pump is needed.
Pumping water isn't essential because there isn't any pressure in the water.
Hence, the correct option is C.

Why is it necessary to reduce the number of chromosomes in gametes, but not in other cells
Answer:
The reduction of chromosomes in the gametes is necessary to make sexual reproduction possible, in which each parent contributes half of their chromosomes and in fertilization a cell with the complete amount of chromosomes is produced, the zygote.
Explanation:
The reduction of chromosomes to form gametes is done by meiosis, a reductive cell division. Sex cells or gametes are haploid cells, i.e. with half the chromosome charge, as each parent must contribute a gamete in the reproductive process.
The union of the parents' gametes is called fertilization and its product is the zygote, whose chromosome charge is complete or diploid.
For a diploid zygote to be formed, it is necessary for the sex cells or gametes to be haploid, or with half of the chromosomes of the species..
The genetic content built of proteins and nucleic acid found in the nucleus of cells are called chromosomes.
The reduction of the chromosome is essential for sexual reproduction.
In this sort of reproduction gametes from each parent fuse to form offspring.Each parent provides half the number of chromosomes (n) to form a complete offspring with the total set of chromosomes (2n).In the process of gamete formation chromosomes, get halved due to meiosis.The reproductive gametes from both the parent combine via fertilization and form the diploid offspring.Therefore for a diploid offspring to be formed the gametes need to be haploid.

Explanation:
The process of cell division by which most of cells divide for growth is called mitosis.
In this process, each cell called mother cell divides to form two identical daughter cells. The daughter cells have the same number of chromosomes as mother cell. It helps in growth and repair of tissues in organisms.
Specific cells of reproductive organs or tissues in animals and plants divide to form gametes., which after fertilisation give rise to offspring.
They divide by a different process called MEIOSES.Which involves two consecutive divisions. When a cell divides by meiosis it produces four new cells instead of just two .
The new cells only have half the number of chromosomes than that of the mother cells.

Rachal Corporation produces and sells a single product whose selling price is $150.00 per unit and whose variable expense is $57.00 per unit. The company's monthly fixed expense is $381,300.
Required:
a. Assume the company's monthly target profit is $9,300. Determine the unit sales to attain that target profit. Show your work!
b. Assume the company's monthly target profit is $18,600. Determine the dollar sales to attain that target profit. Show your work!
Answer:a) if the company's monthly target profit is $9,300, 4,200 units sales is needed
b) if the company's monthly target profit is $18,600, 4,300 units sales is needed
Explanation:
Using The Contribution Margin Approach:
Contribution Margin = Sales expense - variable expense
=$150.00 - $57.00
=$93
Contribution Margin Ratio= Contribution Margin/ sales expense x 100
=93/150 x 100
= 62%
Assume the company's monthly target profit is $9,300.
A) Sales to attain the target profit = [(Fixed expenses + Target profit) ÷ Contribution Margin ratio]
= ($381,300. + $9,300) ÷ 0.62
$390,600 ÷ 0.62
= $630,000
No. of units to be sold =Sales to attain the target profit/ selling price
$630,000/$150.00
=4,200 units
Assume the company's monthly target profit is $18,600
B) Sales to attain the target profit = [(Fixed expenses + Target profit) ÷ Contribution Margin ratio]
= ($381,300. + $18,600 )÷ 0.62
$399,900 ÷ 0.62
= $645,000
No. of units to be sold =Sales to attain the target profit/ selling price
$645,000/$150.00
=4,300 units

If the mantle is made out of soft rock, then I think it would melt due to the heat, but if it was hard, it would just burn, so I firmly believe the rock is hard.
Explanation:
Mantle is a layer on planetary body which is made up of minerals. Mantle is solid as it is made up of heavy metals and solid rocks which makes it rigid.
What is Mantle?A mantle is a layer inside a planetary body bounded by a core and on the above by a crust. Mantle is made up of rock or ices, and is generally the largest and most massive layer of any planetary body. Mantles are on the planetary bodies that have undergone differentiation by density.
The mantle is composed primarily of heavy metals, such as iron, nickel, and others. The state of the mantle was described as plastic. Many divide the mantle into further such as the asthenosphere and lithosphere.
Mantle rocks are soft and able to move over the course of millions of years at great depth and pressure. The transfer of heat and material in the mantle helps to determine the landscape of the planet.
