Answer:

Photosynthesis adds carbon dioxide to the air

Explanation:

Carbon dioxide is an atmospheric gas that is an important part of the biogeochemical cycles. The process of respiration adds carbon dioxide to the air. Thus, option c is correct.

Respiration is a process that can be aerobic or anaerobic and occurs in organisms where the oxygen gas is inhaled while the carbon dioxide is exhaled out from the lungs.

The carbon dioxide is released by the exchange of the gases when the oxygen is used by the cells to break sugar. It uses oxygen for the cellular process and releases carbon dioxide as waste.

The process of photosynthesis is the opposite and uses carbon dioxide to produce sugar and oxygen molecules. The water cycle releases water and the nitrogen cycle releases nitrogen and its compounds.

Therefore, option C. carbon dioxide is produced in respiration.

The process of creating new organisms through sexual reproduction involves fusing the genetic material of two individuals of different sexes.

The gametes, which are specialized sex cells, have chromosomes in their nuclei that contain the genetic information. These gametes are known as sperm in males and eggs in females, respectively.

The two gametes combine during sexual reproduction in a process known as fertilization to form a zygote, the predecessor to an embryo offspring, which receives half of its DNA from each of its parents.

A zygote in a person has 46 chromosomes total, 23 from the mother and 23 from the father. These chromosomes come together to create an offspring that resembles both its parents.

Therefore, The process of creating new organisms through sexual reproduction involves fusing the genetic material of two individuals of different sexes.

The sentence that best describes the temperatures of a city located along a windward coast is C.Cooler summer temperatures than an inland location at the same latitude.

A city on a windward coast experiences cooler summer temperatures than an area inland at the same latitude.

In comparison to an inland site at the same latitude, a city positioned along a windward coast will experience (b) lower summer temperatures. This area's predominant breeze originates from the lake, which will always have a moderating effect (both warmer in the winter and cooler in the summer). Climate, salt intake, hormone levels, carbohydrate intake, degree of physical activity, and some substances like alcohol and caffeine can all have an affect on total body water content.

Temperature is crucial because it affects the chemistry of water. At greater temperatures, chemical reactions typically proceed more quickly. Higher temperature water, especially groundwater, can dissolve more minerals from the underlying rock and will consequently have a higher mineral content.

Answer: Daughter cell that does not receive mitochondria, will not be able to produce the energy needed to carry out cell functions. The cell that receives all the mitochondria, will be able to carry out cellular respiration and thus produce energy.

Explanation:

The mitochondrion is a cellular organelle found in eukaryotic cells, and provides the energy needed to carry out cellular activity. They are characterized by their large size, compared to other cell organelles, and their globular shape. Mitochondria generate most of the chemical energy needed to activate the biochemical reactions in the cell, through a process called cellular respiration. It irefers to a set of biochemical reactions by which certain organic compounds are degraded by oxidation into inorganic substances. The chemical energy produced by mitochondria is stored in an energized molecule called adenosine triphosphate (ATP).

Then, if during cell division, one of the daughter cells does not receive mitochondria, it will not have the necessary organelles to carry out cell respiration and will not be able to produce the energy needed to carry out cell functions. The cell that receives all the mitochondria will have no major problems, it will be able to carry out cellular respiration and thus produce energy.

In this case, the mutation that increased body fat in some of the exotic birds living in a hot environment would likely be considered harmful rather than helpful or neutral.

This is because the increase in body fat caused by the mutation would lead to an increase in body temperature during the hottest parts of the day, which could be dangerous or even fatal for the birds. Birds rely on panting and evaporative cooling to regulate their body temperature, and if their body temperature becomes too high, it can lead to heat stroke and other health problems.

Therefore, while the mutation may have provided some short-term benefit by increasing body fat, it ultimately has negative consequences for the birds' survival in their environment. As a result, the mutation would be considered harmful rather than helpful or neutral.

The ratio between 92 mL and 3.0 fl oz is 46 : 44, or it can be further simplified to 23 : 22.

To find the ratio between 92 mL and 3.0 fl oz, we need to convert the units to a common measurement. Let's convert 3.0 fl oz to milliliters (mL).

1 fluid ounce (fl oz) is equal to approximately 29.5735 milliliters (mL).

Therefore, 3.0 fl oz is equal to 3.0 * 29.5735 = 88.72 mL (rounded to two decimal places).

Now we can express the ratio between 92 mL and 88.72 mL:

92 mL : 88.72 mL

Simplifying the ratio by dividing both sides by the greatest common divisor, we get:

Explanation:

Freeze-thaw occurs when water continually seeps, freezes and expands, it eventually breaks the rock particles apart. Exfoliation is the process which occurs as this  develop parallel to the land surface as a consequence of the reduction in the pressure during uplift and erosion.

Freeze thaw weathering occurs when the water seeps which are present in the rocks or the pores between soil particles and freezes. The expansion of the water molecule creates high pressures, which can widen the force which is present apart the soil particles.

Abrasions generally heals on their own. However, the abrasions which extend into the dermis layer may result into scarring of the tissues upon healing. The most common mechanism of formation of abrasion is due to the friction which is against the epidermis.

All the ova in a woman's ovaries have the exact genetic sequence because they are all derived from the same original cell in her body, which underwent the process of meiosis.

When talking about all the ova (egg cells) in an individual female, which is true about them?Ova, or eggs, are the female gametes (reproductive cells) of most animals and some plants.

An ovum contains one copy of the chromosomes of the mother, including mitochondrial DNA, and is fertilized by a sperm cell, which contains a corresponding complement from the father to form a zygote.

The following statement is true about all the ova (egg cells) in an individual female:They have half the number of chromosomes as her body cells, and the exact same genetic sequence as each other.

Introducing a new organism into an ecosystem can have significant impacts on the stability of that system. This is because every species in an ecosystem is interconnected and plays a vital role in maintaining the balance of the ecosystem. Introducing a new species can disrupt this balance and lead to both direct and indirect effects.

One direct effect of introducing a new organism can be competition for resources. For example, the introduction of the cane toad to Australia led to a decrease in the population of native insect-eating animals, as the toads outcompeted them for food.

Another direct effect of introducing a new organism can be predation. The introduction of the brown tree snake to Guam led to the extinction of several bird species, as the snake had no natural predators and was able to prey on the birds.

Indirect effects of introducing a new organism can include changes in the availability of resources. For example, the introduction of the zebra mussel to the Great Lakes in North America led to a decrease in the abundance of plankton, as the mussels filtered them out of the water.

The introduction of a new organism can also lead to the spread of diseases. For example, the introduction of the Asian tiger mosquito to the United States led to the spread of dengue fever and chikungunya virus.

Finally, the introduction of a new organism can also affect the relationships between existing species. For example, the introduction of the invasive plant Kudzu to the southeastern United States led to changes in the abundance and distribution of native plant species, which in turn affected the populations of native animals that relied on these plants for food and shelter.

In conclusion, introducing a new organism into an ecosystem can have far-reaching effects on the stability of that system. It is important to carefully consider the potential impacts before introducing a new species to an ecosystem.

The resting phase of the cell cycle is called interphase.

Interphase is a critical stage in the cell cycle during which the cell prepares for division by going through different activities such as growth, DNA replication, and protein and organelle production. It is the longest phase of the cell cycle and is separated into three subphases: G1 (Gap 1), S (Synthesis), and G2 (Gap 2).

The cell develops in size, synthesises RNA and proteins, and performs its regular duties during the G1 phase. The cell enters the S phase after passing through the G1 checkpoint. The DNA of the cell is reproduced during the S phase, resulting in the production of two identical copies of each chromosome.

This ensures that during cell division, each daughter cell receives a complete set of genetic material. The cell enters the G2 phase after DNA replication, where it continues to expand and prepares for mitosis.

Interphase is not a real resting phase because the cell is actively engaged in multiple cellular functions. However, because the cell is not visibly dividing at this period, it is commonly referred to as the resting phase.
