Explanation:
Biological organization or levels of organization is defined as the hierarchy of complex biological structures present in the systems that starts with simplest structures and the complexity increase with hierarchy levels.
It organize biological structures from lowest level to the highest level, such as from atom to biosphere.
A functional group of tissues in an organism helps them to perform several activities is called an organ. for example - heart, constitute of several tissues.
A group of cells that functions similarly and have similar structure is called tissue. for example: Epithelial tissue
A living thing that carries out the processes of life is classified as organism. an organism under of the process of reproduction and give birth to other life.
The basic unit of life for all organisms is called a cell. All the organism are made up of different types of cell. for example: Clara cells found in airways of the lungs.
A group of organs that work together to perform specific activities for an organism is classified as an organ system. For example - respiratory system, it constitute of several organs such as lungs (organs), nose, , trachea, pharynx, larynx and bronchi which together performs respiratory function.
Hence, the correct matches of levels of organization that satisfy these definitions are:
1. organ
2. tissue
3. organism
4. cell
5. organ system

_________10. Which of the following groups of plants carry out light dependent and light independent reactions of photosynthesis in separate cells?
A. Plants with chlorophyll C. C3 – plants
B. CAM Plants D. C4 – plants
15 point
Answer:
D. C4 plants
Explanation:
Photosynthesis is the process by which plants and other photoautotrophs synthesize carbohydrates and oxygen from carbon dioxide, water, and light energy in chloroplasts.
Photosynthesis occurs in two stages:
The light-dependent reactions and
The light-independent reactions, or Calvin Cycle.
Light-dependent reactions occur in the presence of sunlight. In these reactions, energy from sunlight is absorbed by chlorophyll and converted into stored chemical energy, in the form of NADPH and ATP. The light-dependent reactions take place in the thylakoid membranes in the grana within the chloroplast.
Light-independent reactions or Calvin cycle: In these reactions, the energized electrons from the light-dependent reactions provide the energy to form carbohydrates from carbon dioxide molecules. There are three phases to the light-independent reactions: carbon fixation, reduction reactions, and ribulose 1,5-bisphosphate (RuBP) regeneration.
C3 plants carry out both the light-dependent and the Calvin cycle within the choroplast organelles. They carry out the Calvin cycle by producing a three-carboncompound called 3-phosphoglyceric acid, hence the name C3.
C4 plants carry out photosynthesis in a two-stage process that first produced a four-carbon intermediate compound in the chloroplast of a thin-walled mesophyll cell. Once synthesized, the plant pumps the intermediate compound into a thick-walled bundle sheath cell, where it splits the compound into carbon dioxide and a three-carbon compound. The carbon dioxide then undergoes the Calvin cycle.
CAM (crassulacean acid metabolism) plants carry out photosynthesis by absorbing sunlight energy during the day, and then using the energy to fix carbon dioxide molecules during the night.

The role of DNA is to move information from the nucleus to the ribosomes for protein synthesis.
NUCLEIC ACIDS:
Nucleic acids are one of the four biomolecules in nature. The two nucleic acids are DNA and RNA. Nucleic acids are generally involved with the storage and coding of genetic information in living cells. DNA specifically stores genetic information in the nucleus of a cell. During transcription, DNA is transcribed into mRNA (messenger RNA) in the nucleus. This means that the information in the DNA is encoded in an RNA molecule. The mRNA functions to transport the genetic information out of nucleus into the ribosome (site of protein synthesis) where translation takes place. Therefore, the role of DNA is to move information from the nucleus to the ribosomes for protein synthesis.Learn more: https://brainly.com/question/241631?referrer=searchResults

At the molecular level, gene duplication often produces novelty in a lineage. This process provides another evolutionary pathway by which a protein can switch functions, without loss of the original function. What analytical approach helped the most to answer the question of evolution in the aldosterone-M receptor pair in the study of Jamie Bridgham and her colleagues
Answer:
Bridgham et al. (2006) showed that the interaction between a steroid hormone (aldosterone-M) and its receptor (mineralocorticoid) evolved by Darwinian gradualism. In this work, the authors demonstrated a primitive affinity between the hormone and its receptor that was initially present in chemically similar but more ancient ligands. This result has implications in understanding the association between gene duplication and the evolution of hormone signaling pathways. For example, in invertebrates, this work reinforces the importance of gene duplication in the existing interaction between paralogous glucocorticoid receptors and their receptor mineralocorticoid genes that were derived from duplication (Thornton 2001).

Review the equations used to describe photosynthesis and respiration (as provided in the introduction and background section of this experiment). Why was it important to use germinated seeds without leaves for this experiment?
Answer:
1. Photosynthesis equation: 6CO2 + 6H2O + (energy) → C6H12O6 + 6O2 Carbon dioxide + water + energy from light produces glucose and oxygen.
Respiration equation : C6H12O6 + 6O2 --> 6CO2 + H2O + ATP
2. Provided that the seeds had leaves the response between the NaOH and the CO2 would be destroyed by the leaves which would change the oxygen levels in the test tube or cylinder.
Explanation:
Photosynthesis and respiration both are the essential parts of the carbon cycle in atmosphere. Photosynthesis use carbon dioxide from the atmosphere while respiration releases carbon dioxide back in to atmosphere. CO2 is the major component that helps in carbon recycle in carbon cycle.
In this experiment it is required to use the germinated seeds without leaves because seeds with the leaves will disrupt the reaction of NaOH and carbon dioxide that will lead to inaccurate oxygen level in the experiment tube.
Thus, the correct answer is :
1. Photosynthesis equation: 6CO2 + 6H2O + (energy) → C6H12O6 + 6O2 Carbon dioxide + water + energy from light produces glucose and oxygen.
Respiration equation : C6H12O6 + 6O2 --> 6CO2 + H2O + ATP
2. Provided that the seeds had leaves the response between the NaOH and the CO2 would be destroyed by the leaves which would change the oxygen levels in the test tube or cylinder.
Which of the following are the four categories of pharmacokinetics? Diffusion, active transport, interspersing, and storage Ingestion, metabolism, interspersing, and excretion Ingestion, settling, movement, and storage Absorption, distribution, metabolism, and excretion
Answer:
Absorption, distribution, metabolism and excretion, it is for that reason that they are collectively known as ADME.
Explanation:
Pharmacokinetics can be referred to as the study of the absorption dynamics of a particular drug, the mechanisms involved in its distribution in the body, its metabolism and finally excretion. Pharmacokinetics is used to quantify the time and rate of drug absorption, thereby it also enables to calculate the temporal changes in concentration of one drug within an organism.

2. Fossil fuel reserves will never be depleted.
3. Fossil fuels are easily renewed.
4. Fossil fuel use does not affect the environment.
Answer:
Option 1. Fossil fuels are cheaper than alternative forms of energy.
Explanation:
Fossil fuels are made by the natural procedure in a more extended time frame, for example, anaerobic decay of the dead living resembling plants, and creatures. These plants and creature's decayed naturally to pilled up to frame coal, or common gases or raw petroleum.
By the utilization of these fuels, the stores are constantly exhausting and as it can not be recharged it will not present in the future. Non-renewable energy sources expand the greenhouse gases in condition and influence it by increasing carbon in climate. Be that as it may, these energizes are less expensive in comparison to different fuels.
Therefore, the right answer is - Fossil fuels are cheaper than alternative forms of energy.
Suppose you are involved in a project studying a population of Dalea purpurea (purple prairie clover), a diploid, bee pollinated plant growing at Cayler Prairie in NW Iowa. You collect a sample from 100 individuals and assay DNA sequence variation at the apetala locus, which controls floral morphology. You find two distinct sequences: L and S. Individuals that are LL have very large petals, LS plants have medium sized petals, and SS plants have small petals. Your sample of plants yields the following observed and Hardy-Weinberg expected (HWE) genotypic counts:.Genotype: Observed Counts: HWE Counts:LL 14 9LS 32 42SS 54 49a. The population is in Hardy-Weinberg equilibrium, giving no indication of the preferences of the bees.b. LS heterozygotes are favored due to hybrid vigor.c. Bees are preferentially visiting smaller flowers resulting in a reproductive advantage for plants with smaller petals.d. LL genotype plants have a reproductive advantage due to their larger flowers.e. Bees preferentially cross-pollinate flowers of the same size (like size mating with like) resulting in inbreeding with respect to genotypes at the apetala locus.
Answer:
Option E
Explanation:
Bees preferentially cross-pollinate flowers of the same size (like size mating with like) resulting in inbreeding with respect to genotypes at the apetala locus.
Inbreeding increases the frequency of homozygousity and deviates from the assumptions of the hardy Weinberg's principle
State the difference between sex limited trains and sex influenced traits. According to your perception which one is more Penetrance? (no more that 3 lines)
Answer: Penetrance can be defined as an extent to which a particular gene or set of gene is expressed in the phenotype.
Explanation:
Sex-limited traits are those traits that can observed in organisms belonging to a particular sex or gender. For example, barred coloring in chicken are observable only in roosters.
Sex-linked traits are traits or genes that are carried by either sex chromosomes are sex linked traits. The traits is sickle cell anemia.
Sex-linked traits is of more penetrance, because the trait will be expressed by either sex chromosome X or Y.

Behavioral and social cognitive theories emphasize the influence of learning and cognition on human behavior.
Behavioral and social cognitive theoriesBehavioral theories, such as classical and operant conditioning, focus on how external stimuli and reinforcement shape behavior. They emphasize the role of environmental factors in shaping and modifying behaviors.
Social cognitive theories, such as social learning theory, highlight the importance of observational learning, modeling, and cognitive processes in understanding behavior. They emphasize that individuals learn not only through direct experience but also by observing others and the consequences of their actions.
Social cognitive theories also emphasize the role of self-efficacy beliefs and how individuals' perceptions of their abilities influence their behavior.
