Explanation:

Active transport moves substances against the concentration gradient, from an area of low concentration to an area of high concentration. It requires the use of energy, usually in the form of ATP.

Hope that helps.

The correct answer is C. Glycolysis is indeed the first stage of cellular respiration, where glucose is broken down into smaller compounds, such as pyruvate and ATP, that can be utilized by the cell for energy. However, glycolysis does not require oxygen to operate, as it can occur in both aerobic (with oxygen) and anaerobic (without oxygen) conditions.

In fact, glycolysis is utilized by muscles for immediate energy during anaerobic conditions, such as during intense exercise, when there is not enough oxygen available for aerobic respiration to occur.During glycolysis, glucose is first phosphorylated, or modified with a phosphate group, in order to trap it within the cell and make it more reactive.

It is then cleaved into two three-carbon molecules, which are further modified and produce two ATP molecules and two NADH molecules as byproducts. These high-energy compounds can then be utilized by the cell for various processes, including muscle contraction.Therefore, while glycolysis is an important stage in cellular respiration and can provide immediate energy to muscles, it does not require oxygen to operate. The correct answer to the multiple-choice question is C.

Water table, also called groundwater table, upper level of an underground surface in which the soil or rocks are permanently saturated with water. The water table separates the groundwater zone that lies below it from the capillary fringe, or zone of aeration, that lies above it. The water table fluctuates both with the seasons and from year to year because it is affected by climatic variations and by the amount of precipitation used by vegetation. It also is affected by withdrawing excessive amounts of water from wells or by recharging them artificially

Dominance is not inherent to an allele or its traits (phenotype). It is a strictly relative effect between two alleles of a given gene of any function; one allele can be dominant over a second allele of the same gene, recessive to a third and co-dominant with a fourth.

All - growth, exchange of gases, excretion, reproduction, and death (option d).

All living organisms undergo various life processes to maintain their existence. Let's analyze each option to determine which life processes are carried out by an organism's cells:

A. Only growth and exchange of gases: While cells are involved in growth and exchange of gases, they also participate in other life processes. This option is incomplete.

B. Only growth, exchange of gases, and reproduction: Cells play a crucial role in reproduction as they are responsible for the production of gametes and the process of cell division. However, there are additional life processes that cells also undertake.

C. Only growth, exchange of gases, excretion, and reproduction: This option includes excretion in addition to growth, exchange of gases, and reproduction. Cells participate in excretion by eliminating waste materials. However, there is one more life process that cells experience.

D. All - growth, exchange of gases, excretion, reproduction, and death: This option encompasses all the mentioned life processes. Cells are involved in growth as they undergo cell division and increase in number. They exchange gases through processes like respiration. Cells excrete waste products. They participate in reproduction through the formation of gametes and cell division. Lastly, cells also experience death as they have a limited lifespan.

The correct statement describing a DNA molecule is B. It has a double helix shape.

DNA (deoxyribonucleic acid) is a molecule that carries genetic information in all living organisms. It is made up of nucleotides, which consist of a sugar (deoxyribose), a phosphate group, and one of four nitrogenous bases (adenine, thymine, cytosine, and guanine).

The structure of DNA is characterized by its double helix shape. The two strands of the DNA molecule are twisted around each other to form a spiral staircase-like structure. The double helix shape is stabilized by hydrogen bonds between the nitrogenous bases: adenine (A) pairs with thymine (T), and cytosine (C) pairs with guanine (G).

The other statements are incorrect:

A. DNA contains the base uracil (U): This statement is incorrect. Uracil is a nitrogenous base found in RNA (ribonucleic acid), not DNA. In DNA, thymine (T) is the corresponding base instead of uracil.

C. DNA contains five phosphate groups per nucleotide: This statement is incorrect. DNA contains one phosphate group per nucleotide. The phosphate group is responsible for linking nucleotides together in the DNA backbone.

D. DNA has a backbone of twenty different nucleotides: This statement is incorrect. DNA has a backbone made up of repeating units of the same nucleotide components (deoxyribose sugar and phosphate group) connected by phosphodiester bonds. There are only four different nucleotides in DNA, which differ based on their nitrogenous bases.

The correct statement describing a DNA molecule is that it has a double helix shape. The double helix structure of DNA is a fundamental feature of its organization and plays a crucial role in storing and transmitting genetic information.

aceptable value is directly accessed where as experimental value is not coinfermed.

DNA alterations that impact nucleosome spacing and consequently transcription lead to epigenetic changes. They don't actually change the DNA sequence.

All of the cells in an organism have fundamentally the same DNA, but different cell types and functions result from qualitative and quantitative variations in the expression of their genes. Therefore, differentiation and development depend on the regulation of gene expression. Although it is believed that epigenetic mechanisms such as DNA methylation, histone modification, and different RNA-mediated processes primarily affect gene expression at the level of transcription, other stages of the process (such as translation) may also be regulated by epigenetic factors.

False. Bob and Judy collected different types of organisms, which means they would have calculated different values for the pollution tolerance index.

The pollution tolerance index is a measure of an organism's ability to tolerate different levels of pollution in its environment. The value is calculated based on the number of pollutants the organism can tolerate and the level at which it starts to experience negative effects. Therefore, it is not possible to say that Bob and Judy ended up calculating the exact same value for the pollution tolerance index.  

Since Bob and Judy collected different types of organisms, they would have calculated different values for the pollution tolerance index. For example, the pollution tolerance index for the crane fly larvae collected by Bob might be different from the pollution tolerance index for the crane fly larvae collected by Judy, even if they collected the same number of individuals.

Answer:

one "A" or one "a"

Explanation:

In diploid species (2n), each individual inherits two gene variants (alleles) for each gene, one from the father and one from the mother. This means that each haploid gamete (n) receives one copy of each homologous chromosome that contains only one form of that gene (i.e., one allele). In consequence, and according to Mendel's First Law, alleles segregate into separate gametes (in this case either "A" allele or "a" allele since the parental genotype is heterozygous for this gene).

Answer:

Changes in abiotic factors can result in extreme problems for some organisms.

For example, if a plant is adapted to low temperatures and the specific are where it lives, has a change in its temperature(thanks to global warming!), this plant will die and this area will no longer support life, which is due to the change in abiotic factor (temperature).

It can also have positive effect on organisms.
