What is true about the relationship of adenine and thymine?- Adenine and thymine are a base pair

- Adenine and thymine are antiparallel

- Adenine and thymine form a covalent bond

- Adenine and thymine are phosphates

Answers

Answer 1
Answer: DNA stands for deoxyribonucleicacid. The deoxy- in the DNA is a short term for deoxyribose. The nucleic acidmolecule has three parts; sugar, phosphate and a base. The phosphate in the DNAacts as a backbone of the molecule. It is also responsible for the DNA’s‘double-helix’ structure. The base has four codes namely adenine, thymine,cytosine and guanine. Adenine and thymine are bse pairs whereas cytosine andguanine are base pairs. They are not to be interchanged. Resulting in one causemutation in the gene. 
Answer 2
Answer:

The relationship between adenine and thymine is that they are base pairs.

Further Explanation:

The nucleic acid makes the DNA. The nucleic acid is made up of nucleotides. Each nucleotide is made up of a phosphate group, deoxyribose, and a nitrogenous base. DNA has mainly four different types of a nitrogenous base.

  • Adenine
  • Cytosine  
  • Thymine
  • Guanine  

RNA also contains guanine, adenine, and cytosine but they do not contain thymine They contain uracil instead of thymine. Chargaff’s rule said that the amount of thymine is the same as the amount of adenine. Also, the amount of guanine is equal to cytosine. The adenine base is paired with thymine in DNA but in RNA adenine pairs with the uracil. The guanine base is paired with the cytosine.

DNA undergoes a replication process wherein duplication of the double-helical structure takes place. It then moves further and forms an RNA molecule through a process called transcription. RNA undergoes RNA processing followed by post-transcriptional modifications which further release out mRNA, rRNA, and tRNA molecules. All the three kinds of RNA enter into the last phase of central dogma called translation. During this, proteins are formed.

Describe the conservation of mass in a food web

Answers

The conversation of mass means that no mass is destroyed nor created. In a food web, every mass (all the living things) die somehow and they all have a balanced diet. Also, they all fit into the web. If an animal is left out, or extincts, they law of conversation of mass is not being applied. 

Meeting present needs while still maintaining resources for future needs is known as

Answers

Answer: Sustainable development

Explanation :

The concept of sustainable development is based on the ideas of sustainable forest management and is derived from the Brundtland Report (1987).

It is basically an organizing principle which states that the human developmental goals should be met by maintaining the stability of the natural systems so that the natural sources can be sustained for future use as well.

So, sustainable development basically means that the present needs should be met without comprising the needs of future generations.



Biologists once assumed that the phenotype of a dominant allele would always be the most common phenotype in a population. Which finding led biologists to a different conclusion? the discovery that most organisms have pairs of like chromosomes and, therefore, a pair of alleles for many traits

the discovery that dominant traits are adaptive and recessive traits help stabilize the population

the discovery of populations in which the phenotype of the recessive allele help a population survive

the discovery that populations undergo evolution when they are exposed to the process of natural selection

Answers

Scientists concluded that the phenotype of a dominant allele would always be the most common phenotype in a population, and that the discovery of populations in which the recessive allele phenotype helps a population survive, and the discovery that populations evolve when they are exposed to the process of natural selection, to understand more we need to know that....

Phenotype distributions

Stabilizing selection. In stabilizing selection, intermediate phenotypes are more apt than extreme phenotypes. For example, medium-green beetles may be better at camouflaging themselves, thus better at surviving in a forest covered with medium-green plants. Stabilizing selection tends to narrow the curve.

Directional selection. An extreme phenotype is fitter than all other phenotypes. For example, if the beetle populationmigrates to a new environment with dark soil and vegetation, dark green beetles can hide better and survive longer than lighter beetles. Directional selectionshifts the curve towards the most favorable phenotype.

Disruptive selection. The phenotypes of the two extremes are fitter than those in the middle. For example, if the beetles migrate to a new environment with patches of light green moss and dark green bushes, both the light green and dark green beetles will be able to hide better (and survive) than the medium green colored beetles. Diversifying selection produces multiple peaks on the curve.

Based on this information, we can conclude that the following statements:

  • The discovery of populations in which the phenotype of the recessive allele help a population survive
  • The discovery that populations undergo evolution when they are exposed to the process of natural selection

All this information is of great importance to understand the phenotypes of populations of living beings.

While hiking in a rural area, you encounter a wetland and conclude that it's a swamp. Which feature helped you reach this conclusion? A. It contains a variety of trees and shrubs.
B. It contains a number of carnivorous plants.
C. It's located near a lake.
D. It's located near the coast.

Answers

Answer:

A. It contains a variety of trees and shrubs.

Explanation:

The area which is wet most of the time and the land is covered with woody plants such as shrubs and trees is called swamp. Swamp is generally found near rivers or streams because rivers bring nutrients to the swamp. It is very useful for mankind because it helps keep the land around them from flooding.

Answer:

that the doorknob isn't used that recently by students, since they don't really use that to study.
Brass doorknobs exhibit an effect known as The Oligodynamic Effect.

This property of a metal means that it will react with the amine groups of enzymes or protein found in bacteria, and kill them.
