All of the following are true about thymine dimers EXCEPT: the type of repair that is done to fix them is called nucleotide excision repair they are caused by UV radiation damage that fuses thymines that are next to each other on the same strand individuals with xeroderma pigmentosa (XP) are unable to repair this type of DNA damage, leading to cancer cell development they are caused by UV radiation damage to thymines that are opposite each other on different DNA strands

Answers

Answer 1

Answer:

Option 4, they are caused by UV radiation damage to thymines that are opposite each other on different DNA strands

Explanation:

Thymine dimer is formed on adjacent thymine and hence they lie next to each other on the same strand. They do not lie on strand that are opposite of  each other on different DNA strand.

Hence, option 4 is correct

Answers

Explanation:

i dont.know im in that qt


Carbon enters all food webs, both terrestrial and aquatic, through autotrophs, or self-feeders. Almost all of these autotrophs are photosynthesizers, such as plants or algae. Autotrophs capture carbon dioxide from the air or bicarbonate ions from the water and use them to make organic compounds such as glucose.

Population: a group of an individual species

Community: a group of multiple species

Organism: A living thing

Ecosystem: ecosystems include more than a community of living organisms (biotic) interacting with the environment (abiotic)

Biome: a set of ecosystems sharing similar characteristics with their abiotic factors adapted to their environments.

Biosphere: the sum of all the ecosystems established on planet Earth. It is the living (and decaying) component of the earth system.

Explanation:

The definition of the given terms are as follows:

Organism: They may be defined as a living thing that has an organized structure and the ability to react to stimuli, reproduce, grow, adapt, and regulate the mechanism of homeostasis.Population: It may be defined as the group of individuals belonging to the same species living in the same area at a given time.

What is Community?

A community may be characterized as a group of individuals belonging to different species living in the same area at a given time.

An ecosystem may be defined as the place or an area where members of different species live together and interact with one another for the purpose of food, shelter, space, and mating partner.

A biome may be characterized as a very large ecosystem that is significantly running in nature in an unmanaged area. While the biosphere may be defined as the region of the Earth where life can be found, including the soil, water, and air.

Therefore, the definition of each term is well described above.

Describe at least two costs and two benefits of using a desalinization plant to obtain more freshwater?

Answers

Answer:

Advantages:

1. provide drinking water in desertic regions

2. excellent water quality  

Disadvantages:

1. high cost to obtain freshwater

2. possible harmful effects on the aquatic ecosystem

Explanation:

Desalinization plants are centers that provide an independent source of water, critical for human needs. Desalination plants function to remove salt from seawater, thereby turning this water into potable drinking water, which is of vital importance for areas where freshwater is scarce (e.g., desertic regions). Moreover, desalinization plants meet (or even may exceed) standards for water quality because they are prepared to remove impurities (not only salts) from seawater. Nonetheless, desalinization plants may also exhibit disadvantages. In the first place, desalinization is an expensive process that requires an important amount of electricity to push water through a filter (desalinization occurs via reverse osmosis). Finally, desalinization plants may alter aquatic ecosystems in a negative way since the discharge of seawater modifies the salinity and decreases the oxygen levels in the water at the disposal site.

During which process does heat transfer occur because of density differences in water or air?
A. Conduction
B. Pollution
C. Radiation
D. Convection
2. Explain your answer.

Answers

Answer: D. Convection

Explanation: As water's temperature increases in the presence of a heat source, it will become less dense and rise. As it moves up and away from the heat source, it cools and becomes denser and sinks.

Answer:

The correct answer is D. Convection.

Explanation:

Convection occurs due to the differences in density, and only happens in gases or liquids. The heat is transferred by the movement of a heated fluid, which is air or water.

Forests

Explanation:

Forests have also sanitary influences upon environment due to the production of oxygen through photosynthesis.

The study of the environment is called ecology. There are two types of factors for an ecosystem and these are a biotic and abiotic factors.

The correct answer is light

What is photosynthesis?

The process of the formation of food by trapping the sunlight with the help of chloroplast is called photosynthesis.

According to the question, the most influential factor which affects the environment is light as all the plants directly depend on the light for the formation of food and all the other species are dependent on plants either directly or indirectly.

These coal-powered factories had caused huge damage to the environment. As a result, the government enacted anti-pollution laws to preserve and protect the environment. Predict what would happen to the white-colored moth population when the environment is restored?​

Answers

Answer:

it would drastically increase

Explanation:

Studies have shown that the increased amount of pollution has led to a drastic decline in the number of white-colored moths. Therefore, if pollution decreased and the environment was restored, then white-colored moths would once again thrive and their population would drastically increase. This is because, with less pollution, the white-colored moths are much harder for predators to see and are able to blend in easier with their surroundings. This therefore, allows them to survive long enough to reproduce.

how replication occurs.

Answers

Answer: Meselson & Stahl reasoned that these experiments showed that DNA replication was semi-conservative: the DNA strands separate and each makes a copy of itself, so that each daughter molecule comprises one "old" and one "new" strand. The semi-conservative model, in which each strand of DNA serves as a template to make a new, complementary strand, seemed most likely based on DNA's structure. ... From the patterns of DNA labeling they saw, Meselson and Stahl confirmed that DNA is replicated semi-conservatively.

At the organism level, homeotic genes control the differentiation and development of cells during embryonic development.

Transcription factor:

Transcription factors are proteins involved in the process of converting, or transcribing, DNA into RNA.  Transcription factors include a wide number of proteins, excluding RNA polymerase, that initiate and regulate the transcription of genes.  Regulation of transcription is the most common form of gene control.

The stages of mitosis were originally defined by cellular features observable through a light microscope.

b. False

Answers

Answer: TRUE

Explanation:

The cell division that takes place during the growth and development of an organism is in an as MITOSIS. Mitosis takes place in somatic cells that is, body cells that are not involved in the production of gametes. The difference stages of mitosis were originally defined by cellular features observable through a LIGHT MICROSCOPE. These stages includes:

--> PROPHASE: when viewed under a light microscope, each chromosome shortens and thickens and is seen to consist of two chromatids. The Centriole begin to separate.

--> METAPHASE: The nuclear membrane disappears, a spindle forms, the chromosomes line up across the middle of the cell and become attached to the spindle fibres at their centromeres.

--> ANAPHASE: The sister chromatids are pulled apart to opposite ends of cell as the spindle fibres contract.

--> TELOPHASE: A nuclear membrane forms around each set of chromatids, and the cell divides into two daughter cells.
