Which two activities provide the reactants for cellular respiration

Answer:

See the answer below

Explanation:

It may seem that the options have been omitted in this question. However, in order to evaluate the claim that a mean from a particular group is statistically higher or lower to a mean from another group, there would be a need to compare the two means.  

Mean comparison or testing for a significant difference between means can be carried out using the Student's t-test or one-way Analysis of Variance (ANOVA).

When the means being compared are just for 2 groups as indicated in the illustration, Student's t-test and one-way ANOVA can be used. However, once there are more than 2 group means being compared, one-way ANOVA will only be applicable.

The addition of fresh water from a stream reduces the salinity of the ocean water at the point of discharge.

When a freshwater stream flows into the ocean, it brings a lower concentration of salt compared to the seawater. This dilutes the ocean water, reducing its salinity at the point where the freshwater is discharged.

However, the effect on the ocean's overall salinity is usually insignificant as the ocean is a vast body of water with a huge volume and the addition of freshwater is relatively small.

Additionally, the movement of ocean currents disperses the freshwater, reducing the localized effect even further. Nevertheless, significant inputs of freshwater from melting glaciers or heavy rainfall can have a larger impact on the ocean's salinity in the affected regions.

Homologous chromosomes are paired because they carry the same genes in the same order, although the alleles for each trait may differ.

During meiosis, the homologous chromosomes align during prophase I and exchange genetic material through a process called crossing over, which contributes to genetic diversity.In human beings, a pair of homologous chromosomes is present in every cell, one from each parent.

In females, the two X chromosomes are homologous pairs, while in males, the X and Y chromosomes are not homologous pairs since they carry different genes. During fertilization, the homologous chromosomes from the two parents pair up, and each gamete contains only one of each homologous chromosome.

Since GFR decreases with age , then the average value of GFR will be 90 to 120mL/min/1.73 m2

GFR (Glomerular Filtration Rate) can be said to be  the amount of plasma entering Bowman’s capsule per minute. It is the renal plasma flow × the fraction that enters the renal capsule (19 percent).578*0.19 = 110 mL filtrate/min. Glomerular filtration rate (GFR) is referred to as a blood test that checks to control how well your kidneys are working.

We can deduce from the National Kidney Foundation, normal results range from 90 to 120 mL/min/1.73 m2. Older people will have lower than normal GFR levels, since GFR decreases with age

In other to improve and have a healthy GFR it is important to avoid regular in-take of  processed foods  and choose fresh fruits and vegetables instead. Following a low-salt diet is essential because of it effect on blood pressure.

Explanation:

This is the equation that comes with the question;

C6H12O6 + O2 ⇒ CO2 + H2O

If we observe it, we will see that equation is not balanced, the number of atoms of hydrogen, carbon and oxygen that are present on the Left side are less than the numbers of atom on the right side. The number of atoms of Carbon, Hydrogen and Oxygen on the left side are; 6, 12 and 8 respectively, while on the right side of the arrow we have 1, 2 and 3 atoms respectively.

If we balance the cellular respiration equation.

THEN CORRECT CELLULAR RESPIRATION EQUATION IS

C6H12O6 + 6O2 ⇒ 6CO2 + 6H2O

where there are 6 atom of carbon, 12 atoms of hydrogen and 18 atoms of Oxygen on both side of the arrow.

Therefore, To balance the inputs and outputs of cellular respiration, there should be the same number of carbon, oxygen, and hydrogen atoms on each side of the arrow

Explanation:

segregation of alleles

codominance of traits

polygenic expression of traits

independent assortment of alleles

A pea plant that is heterozygous for the tall phenotype can produce short offspring when self-pollinating, and this happens due to the independent assortment of the alleles.

The mendel explains how the traits are expressed and explained by different laws, and out of those laws, one is the law of independent assortment, where he explains that alleles can independently assorted and segregate and form the gametes. The pea plant is an example. In the pea plant, the heterozygous plant for height is Tt, and these two alleles can segregate and can form both tall and short plants. When the two Tt self-pollinate, then three of them are tall and one is short.

Melanin absorbs dangerous UV rays that can do severe skin damage. But melanin can't absorb all the UV rays, and some people don't have much melanin in their skin.

Explanation:

The sun is by far the strongest source of ultraviolet radiation in our environment. Solar emissions include visible light, heat and ultraviolet (UV) radiation. Just as visible light consists of different colours that become apparent in a rainbow, the UV radiation spectrum is divided into three regions called UVA, UVB and UVC. As sunlight passes through the atmosphere, all UVC and most UVB is absorbed by ozone, water vapour, oxygen and carbon dioxide. UVA is not filtered as significantly by the atmosphere.Ozone is a particularly effective absorber of UV radiation. As the ozone layer gets thinner, the protective filter activity of the atmosphere is progressively reduced. Consequently, the people and the environment are exposed to higher levels of UV radiation, especially UVB.

Ozone depletion is caused by human-made chemicals released into the atmosphere and will continue until the use of chlorine and bromine compounds is drastically reduced. International agreements, in particular the Montreal Protocol, are gradually succeeding in phasing out the production of ozone-depleting substances. However, the long life span of the chemicals already released will cause ozone depletion problems to persist for many years to come. A full recovery of the ozone level is not expected until 2050.Most UV-A does reach the surface, but UV-A does little genetic damage to tissues. UV-B is largely responsible for sunburn and skin cancer, though it is mostly absorbed by ozone before reaching the surface. Levels of UV-B radiation at the surface are especially sensitive to the amount of ozone in the stratosphere.

If the number of nitrifying bacteria decreased, it would have a negative effect on the nitrogen cycle.

Nitrifying bacteria are responsible for converting ammonia (NH3) into nitrite (NO2-) and nitrate (NO3-), which are important forms of nitrogen that can be used by plants for growth. Without nitrifying bacteria, the process of nitrification would be slowed down or stopped, leading to a decrease in the amount of available nitrite and nitrate for plants. This can have a cascading effect on the entire ecosystem, as other organisms that rely on plants for food would also be impacted.

Additionally, a decrease in nitrifying bacteria would also affect the process of denitrification, which converts nitrate back into nitrogen gas and releases it into the atmosphere. This would lead to a build-up of nitrate in the soil, potentially leading to soil eutrophication, and affecting the water quality.

Explanation:

To systematically investigate the yellowing of the plant's leaves, you can follow these steps:

1- Observation: Observe and note that after five days in the room, most of the plant's leaves have turned yellow.

2- Question: Ask yourself, "Why did the leaves of the potted plant turn yellow after being kept in the room for five days?"

3- Hypothesis: Make an educated guess about the possible cause of the yellowing. For example, you could hypothesize that the lack of sunlight in the room caused the leaves to turn yellow.

4- Experiment: Design an experiment to test your hypothesis. Place another potted plant in a different room with similar conditions but with sufficient sunlight.

5- Data collection and analysis: Record and compare the condition and color of the leaves in both plants after five days. If the plant with sunlight has green leaves while the one in the room still has yellow leaves, it supports your hypothesis.

6- Conclusion: Based on your observations and the results of the experiment, conclude that the lack of sunlight may be the cause of the yellowing of the plant's leaves.

By following these steps, you can systematically ask the right questions, form a hypothesis, conduct an experiment, and reach a conclusion using the scientific learning process.

Hope it helps!!! :)

A systematic method to ask the right questions, make educated guesses, conduct scientific experiments, and arrive at a conclusion is to follow the scientific method as follows:

A hypothesis could be; The yellowing of the plant's leaves is a result of reduced exposure to sunlight.

The yellowing of leaves in a potted plant kept away from sunlight is primarily due to a process called chlorosis which is the loss or reduction of chlorophyll in plant tissues.

When a potted plant is kept away from sunlight or receives insufficient light, the plant is unable to carry out photosynthesis. Consequently, the chlorophyll content in the leaves decreases, and they start to lose their green color.

The lactose operon is like a group of genes that help break down lactose, which is a sugar found in milk. And if a bacterium wants to use lactose for energy, it needs to break it down first.

So, if scientists wanted to engineer a bacterium that could triple the digestion of lactose in the operon, they might add or subtract certain parts of the operon to make it more efficient at breaking down lactose. For example, they might add extra copies of genes that are responsible for breaking down lactose, or they might remove parts of the operon that are slowing down the digestion process.

But, like, to be honest, I'm not really sure exactly which parts they would add or subtract. I think it would depend on the specific bacterium they're working with and the specific genes in the lactose operon. And the scientists would need to do a lot of experiments and testing to figure out what works best.

Mitosis and Binary Fission are very similar except when comparing the size of the new daughter cells relative to the original parent cell is a false statement.

A cell prepares for cell division by replicating its chromosomes, segregating them, and creating two identical nuclei during the mitotic phase. The cell's contents are often evenly divided into two daughter cells with identical genomes after mitosis.

A cell copies each chromosome during mitosis and distributes one copy to each of its two daughter cells. With regard to our example of an instruction manual, it is crucial that each person receive a duplicate of each page.

Mitosis follows the same pattern. Each chromosome must be delivered to each of our cells exactly once, without any errors, or the cells may have problems carrying out the genetic instructions.

Therefore, Mitosis and Binary Fission are very similar except when comparing the size of the new daughter cells relative to the original parent cell is a false statement.
