______ is a nonliving part of an ecosystem that gives plants the energy they need to make food. A) sunlight B) a germ C) wind D) oxygen gas

Answer:

C) If the liver is placed in an acidic solution, then the reaction rate will decrease.

Explanation:

Placing the pH in an acidic solution will cause denaturing of the enzyme catalase. Catalase is an enzyme which is in our liver and it breaks hydrogen peroxide into water and oxygen so as to protect our body from harmful effects of hydrogen peroxide. Catalase works best at 7 pH value. If we will place the liver in acidic solution it will cause denaturation of catalase. Denaturation alters the shape of the active site of enzymes. Active sites are the sites in enzymes which are meant for substrate binding. They have a shape which fits a specific substrate. So, if the shape of the active site will change due to denaturation, the substrate will no longer be able to fit into the enzyme and therefore reaction will not take place.

Answer:

C)frame-shift

Explanation:

Since the protein-encoding DNA is divided into codons of three bases each, insertions and deletions can alter a gene to the point that its message loses its meaning. These changes are called the reading frame offset.

For example, consider the phrase: "The fat cat sat". Each letter represents a codon. If we delete the first letter and try to analyze the sentence in the same way, it doesn't make sense. In frame-shift, a similar error occurs at the molecular level, causing the codons to be analyzed incorrectly. This usually produces useless proteins.

Answer: The correct answer is- Oxygen is released as a gas after water is split.

Photosynthesis is a process by which green plants and animals synthesize their own food using CO₂ ( carbon dioxide) and H₂O ( water) in the presence of sunlight. It is divided into two phases that is light dependent ( occurs in thylakoid membrane of chloroplast) and light independent phase ( occurs in stroma of chloroplast)

In the first phase, energy from sunlight gets converted to chemical energy that is ATP and NADPH and water is splitted into electrons, protons and molecular oxygen. This occurs at PS II ( photosystem II), which is a structure present in the thylakoid membrane of chloroplast. The electrons released then participate in the electron transport chain.

Molecular oxygen is released in the atmosphere.

My answer will be that the valence of the Carbon atom is (+4) and that of each Oxygen atom is (-2). The CO2 molecule is formed by covalent bonds, in other words: C (+4) + O2 (-4) = 0.

The answer to your question are the Somatic cells. They are all of the cells that are not related to reproduction. Hope this helped!

Answer: Somatic cell

Explanation:

A somatic cell is any cell forming the body of an organism that is not a gamete, germ cells or undifferentiated stem cell. For example, skin cell, muscle cell, blood cell and others. Thereby, they are all cells that make up an organism and are not used to form a new organism during reproduction. New somatic cells are created through mitosis, when a cell divides to form two identical diploid cells. The major purpose of this type of cell division is for growth and to replace cells.

Germ cell give rise to the gametes, which are reproductive cells (egg or sperm). They are haploid cells because they carry only one copy of each chromosome. They create new gamete cells through meiosis. And undifferentiated stem cells can divide to produce other cells that continue as stem cells or cells that are destined to differentiate.

Answer - Sub-Saharan Africa

P.S. Next time when you post a question please make sure to include all the given information in the question.

Hope This Helps :)

Final answer:

The largest number of child deaths in low-income countries is caused by pneumonia, diarrhea, and malaria. These are often linked with environmental factors like indoor air pollution, poor water quality, and malnutrition, and are preventable with better healthcare and sanitation practices.

Explanation:

According to the World Health Organization, the most frequent causes of death for children under five in low-income countries include pneumonia, diarrhea, congenital anomalies, preterm birth complications, birth asphyxia/trauma, and malaria. A significant number of these deaths can be prevented with interventions like immunizations, proper nutrition, access to safe water and food, and quality healthcare. The largest number of child deaths occurs due to environmental factors such as indoor air pollution from unprocessed solid fuels used for cooking and heating, poor water quality, sanitation, and hygiene that lead to diarrheal diseases, and infectious diseases like malaria, which is particularly prevalent in the African region. Malnutrition considerably contributes to child mortality and is often linked with environmental conditions. Due to the scarce healthcare resources in low-income countries, there is an urgent need for improved medical access to reduce these preventable deaths.

Answer:

Point source pollution and nonpoint source pollution are both potentially harmful to the environment. The main difference between point source pollution and nonpoint source pollution is that point source pollution is easier to track to its source. The source of pollution is easily identifiable in point source pollution, but not in nonpoint source pollution. For this reason, point source pollution is easier to regulate and therefore easier to control. This makes nonpoint source pollution potentially more harmful to the environment.

Genotype for a recessive trait found on the female chromosome is b.

A female with two copies of a recessive allele on her X chromosomes is homozygous for an X-linked recessive trait. She will pass on this trait to her male offspring. Female carriers with one recessive and one dominant allele can pass on the carrier status or the disease to their children.

The genotype for a recessive trait carried on the female X chromosome is represented by two alleles, one on each X chromosome. When it comes to X-linked recessive traits, females need to inherit two copies of the recessive allele to express the trait. If they inherit only one recessive allele and one dominant allele, they are considered carriers and do not usually show the trait.

In humans, ailments such as certain forms of color blindness, hemophilia, and muscular dystrophy are examples of X-linked recessive conditions. A female who is homozygous for a recessive X-linked trait (meaning she has two copies of the recessive allele, one on each X chromosome) will pass this trait on to all of her male offspring. This is because males have one X and one Y chromosome, and they will inherit the Y chromosome from their father and the X chromosome from their mother. If a woman is heterozygous for the trait (having one recessive and one dominant allele), she may not express the disease but can still pass on the carrier status to her daughters or the disease to her sons.

Critique the phrase airspeed velocity of a swallow as Its redundant. The velocity of a flying object already includes its airspeed.

It's obvious, you'll be thinking of African or European swallow; we might consider the West African swallow, or the South African Cave swallow, however, choosing one between these two would be completely arbitrary- and neither is it sufficiently studied to provide the absolute data we need.

Not withstanding, there is an accepted way to estimate the airspeed of a bird using Strouhal ratio's equation. This states that "the frequency of wingbeats multiplied by their amplitude and divided by the airspeed of the bird provides a semi-constant value." This is known as the Strouhal number and averages between 0.2 and 0.4 for most birds, with a higher number denoting a less efficient flight pattern.

Flight is (for those poor people who we're not opportune to watch it) clearly very efficient, seeming almost effortless. So we’ll go for the lower end of Strouhal numbers in our working, giving us (drumroll please), an airspeed velocity of 11–16 metres per second. That’s 40–60 kilometers per hour.

Therefore, Critique the phrase airspeed velocity of a swallow as Its redundant. The velocity of a flying object already includes its airspeed.

A) They release radioactive waste.

Explanation:

Fossil fuels are non renewable resources  do not release radioactive wastes / materials, but they do release greenhouse gases, causing air pollution.

Final answer:

The statement not associated with the drawback of using fossil fuels is that they release radioactive waste. Fossil fuels cause air pollution and release greenhouse gases and are non-renewable, but do not create radioactive waste. Thus, option A is correct.

Explanation:

The question asks to identify which statement is not a drawback of using fossil fuels. The correct answer is A. They release radioactive waste. This is a drawback associated with nuclear power, not fossil fuels. However, fossil fuels are known to cause significant air pollution, emit greenhouse gases, and are non-renewable resources.

Fossil fuels, such as coal, oil, and natural gas, take millions of years to form and hence are classified as non-renewable. The combustion of these fuels releases large quantities of carbon dioxide (CO2), which is a greenhouse gas that contributes to global warming. Additionally, the burning of fossil fuels results in the release of pollutants into the air, contributing to air pollution.
