An example of an energy-requiring reaction is_ photosynthesis; which uses energy from the sun to produce sugars; an example of an energy-releasing reaction is cellular respiration which releases the energy in sugars.

In a process known as photosynthesis, plants and trees combine carbon dioxide from the atmosphere with energy from the sun to create the food they require to survive and develop. The trees and plants in forests help to produce oxygen as a consequence of photosynthesis by storing carbon above and below the ground.

The process by which sugar is broken down in the presence of oxygen in the mitochondria of organisms (animals and plants) to release energy in the form of ATP is known as cellular respiration. Water and carbon dioxide are waste products of this process.

Answer:

Option C.

Explanation:

Just took that test, got it right. Hope this helps :)

The following is true regarding the process of transcription c. Transcription occurs for individual genes.

Transcription takes place for individual genes.

Not all genes are transcribed all of the time. Instead, transcription is managed in my opinion for every gene (or, in bacteria, for small businesses of genes that can be transcribed together). Cells cautiously modify transcription, transcribing simply the genes whose merchandise is wanted at a specific moment.

Not all of the genes on your frame are grown to become on on the equal time or withinside the equal cells or components of the frame. For many genes, transcription is the important thing on/off manipulate point: If a gene isn't always transcribed in a cell, it cannot be used to make a protein in that cell.

The goal of transcription is to make an RNA replica of a gene's DNA sequence. For a protein-coding gene, the RNA replica, or transcript, consists of the statistics had to construct a polypeptide (protein or protein subunit). Eukaryotic transcripts want to undergo a few processing steps earlier than translation into proteins.

Hence it is clear that Transcription occurs for individual genes and this is true.

Answer:

C. New generations are better suited to survive than previous generations.

Explanation:

According to the evolutionary theory proposed by Darwin, evolution can be defined as a gradual process by which organisms change over time. Natural selection is the mechanism by which evolution occurs: organisms exhibit variation that may be passed from one generation to the next, and part of this variation confers an adaptive advantage. The organisms that are better adapted to their environment will have more chances to survive and reproduce, and they will pass these phenotypic changes to the next generation. At the species level, these phenotypic changes between generations are gradual, it is for that reason that evolution is a slow gradual process. In consequence, it is expected that new generations are better adapted to survive in the same environmental conditions.

Explanation:

Transcription regulators are proteins that control gene expression by regulating the transcription of genes. If a chemical that can prevent transcription regulators from functioning is made and is used to stop root growth, then the transcription regulator that would be inhibited with this chemical is WOX5.

WOX5 (WUSCHEL-RELATED HOMEOBOX 5) is a transcription factor that plays a vital role in the growth of plant roots. WOX5 acts as a transcriptional regulator and binds to the DNA to activate or inhibit gene expression. WOX5 is expressed in the quiescent center (QC), which is a group of cells located at the tip of plant roots.

The QC is responsible for maintaining the stem cell population in the root and is essential for root growth. WOX5 plays a critical role in root growth by regulating the differentiation of stem cells into specific cell types. If the function of WOX5 is inhibited, then the differentiation of stem cells is affected, and root growth is stopped.

Therefore, to stop root growth, a chemical that can prevent the functioning of transcription regulators should be developed to inhibit WOX5.

Answer: To stop root growth, the transcription regulator that would be inhibited with a chemical is WOX5.

During mitosis in animal cells, the phase do centrioles begin to move apart is prophase stage.

Prophase marks the start of mitosis and is preceded by interphase. During the prophase stage, the centrosomes divide and move away from one another, and microtubules begin to develop from the centrosomes, forming the spindle apparatus. The prophase stage of mitosis is characterised by the disintegration of the nuclear envelope, which is a double membrane that surrounds the nucleus. In addition, the chromatin threads begin to condense into discrete chromosomes during the prophase stage.

In animal cells, the centrioles are the tiny, self-replicating organelles that aid in cell division by aiding in the formation of the mitotic spindle apparatus. The mitotic spindle is critical for the segregation of chromosomes in the dividing cells. It is therefore established that the centrioles begin to move apart during the prophase stage in animal cells during mitosis. So therefore centrioles begin to move apart during the prophase stage in animal cells during mitosis.

Multiple allelic inheritance in humans refers to a situation where a gene has more than two allelic forms. It implies that more than two alleles determine the trait expression, thus resulting in many possible phenotypic outcomes. There are different examples of multiple allelic inheritance in humans, such as ABO blood group inheritance.

The ABO blood group is one of the classic examples of multiple allelic inheritance in humans. The inheritance of blood groups involves three alleles: A, B, and O, where A and B are codominant and O is recessive. The gene responsible for blood group is located on the chromosome 9, and it determines the presence or absence of antigens on the surface of red blood cells.

A person can either be blood group A, B, AB, or O, depending on the combination of alleles inherited from their parents. For instance, a person who inherits the A allele from one parent and the B allele from the other will have the AB blood group.

Another person who inherits the O allele from both parents will have blood group O. Similarly, someone who inherits A allele from both parents will have blood group A, and the same applies to those who inherit the B allele from both parents.

Therefore, in conclusion, the ABO blood group is a classic example of multiple allelic inheritance in humans. It is a type of inheritance where a gene has more than two allelic forms, and it results in many possible phenotypic outcomes.

mitotic spindle is the answer

During anaphase mitotic spindle is attached at the centromere of each sister chromatid because it attaches the chromosome to the opposite spindle pole.

Protein complexes connect microtubules to the chromosomal midpoint (the centromere) (kinetochores). The connected microtubules depolymerize and shorten, causing movement that pushes chromosomes toward centrosomes situated at either pole of the cell.

The mitotic spindle is a structure that separates the chromosomes. The mitotic spindle is composed of multiple long proteins known as microtubules that are connected to a chromosome at one end and to the cell pole at the other.

The anaphase stage in the cell cycle prepares to spare sister chromatids reday for moves it toward the opposite spindle pole.

Acid deposition, also known as acid rain or acid precipitation, refers to the deposition of acidic substances from the atmosphere onto the Earth's surface. It is primarily caused by emissions of sulfur dioxide (SO2) and nitrogen oxides (NOx) from human activities, particularly the burning of fossil fuels such as coal and oil in power plants, industrial processes, and vehicle emissions.

The chemical equations involved in acid deposition formation are as follows:

SO2 (sulfur dioxide) + O2 (oxygen) + H2O (water) → H2SO4 (sulfuric acid)

NOx (nitrogen oxides) + OH (hydroxyl radical) → HNO3 (nitric acid)

Acid deposition can occur in two main forms: wet deposition and dry deposition.

The villi are a crucial part of the small intestine, and their primary function is to absorb small nutrient molecules from the digestive tract. They are small, finger-like projections that protrude from the lining of the small intestine, which increases the surface area of the small intestine available for absorption.

More than 100 words follow. When food is broken down in the stomach by digestive juices, it becomes a thick liquid known as chyme. The chyme moves slowly through the pyloric sphincter into the small intestine, where the majority of nutrient absorption takes place.

The villi are an essential component of the small intestine's lining, which absorbs nutrients from food as it passes through the digestive tract. They act as an interface between the food and the bloodstream. The cells lining the villi secrete enzymes and other digestive juices that break down nutrients into smaller molecules, which can then be absorbed into the bloodstream.
