Match the following enzymes involved in DNA replication with their functions.
a. DNA ligase
b. DNA polymerase
c. DNA gyrase
d. helicase
Answer:
DNA ligase is an enzyme which can connect two strands of DNA together by forming a bond between the phosphate group of one strand and the deoxyribose group on another.
DNA polymerase is an enzyme that synthesizes DNA molecules from deoxyribonucleotides, which are the building blocks of DNA. The enzymes play an essential role in DNA replication, usually working in pairs to produce two matching DNA stranges from a single DNA molecule.
DNA gyrase is an essential bacterial enzyme that catalyzes the ATP-dependent negative super-coiling of double-stranded closed-circular DNA
Helicases are enzymes that bind and may even remodel nucleic acid or nucleic acid protein complexes. There are DNA and RNA helicases. DNA helicases are essential during DNA replication because they separate double-stranded DNA into single strands allowing each strand to be copied.
Explanation:
DNA ligase seals the fragment, DNA polymerase adds a new nucleotide, DNA gyrase unwinds the DNA, and helicase makes a dent in double helix.
What is DNA replication?DNA replication is the physiological method that generates two identical replicas of DNA from a single original DNA molecule in molecular biology.
DNA replication takes place in all living organisms and is the most important component of biological inheritance.
Helicase, primase, DNA polymerase, and ligase are the four main enzymes that aid in DNA replication.
Many proteins and enzymes play a role in DNA replication, including: Topoisomerase: This enzyme relaxes the super-coiled nature of DNA. Helicase: Helicase is a protein that separates the two strands of DNA at the replication fork.
The fragment is sealed by DNA ligase, a new nucleotide is added by DNA polymerase, the DNA is unwound by DNA gyrase, and a dent in the double helix is made by helicase.
Thus, this can be the match for the given scenario.

Explanation:
The way people use land can affect the levels of nutrients and pollution in soil. Any activity that exposes soil to wind and rain can lead to soil loss. Farming, construction and development, and mining are among the main activities that impact soil resources.Over time, many farming practices lead to the loss of soil.
And as for land ita the same we construct bulidings and dig mines it damages the land. And as land is imporatant for survival of all the of the biosphere we are definntelt responsible for it as well.
Our water resources face a host of serious threats, all of which are caused primarily by human activity. They include sedimentation, pollution, climate change, deforestation, landscape changes, and urban growth. And again it it affects the biodiversity of water preety badly. The marine animals suffer because of our causes.
Biomagnification occurs when the concentration of a pollutant increases from one link in the food chain to another (i.e. polluted fish will contaminate the next consumer and continues up a tropic food web as each level consumes another) and will result in the top predator containing the highest concentration levels. It starts a chain reaction originating from our doings.
pollutants accumlate in bodies of fishes beacuse, they eat unhygienic and non fishFriendly stuffs,it passes on to onother fish.
Humans have come to rely on fossil fuels to power cars and planes, heat homes, and run factories. Doing these things pollutes the air with carbon dioxide. Other greenhouse gases emitted by natural and artificial sources also include methane, nitrous oxide, and fluorinated gases. It leads to destroying of ozone layer in antartica and durther affecting the biodiversity of animals as well as of ourselves.
Biodiversity is the amount of variety of life on Earth. Healthy ecosystems and rich biodiversity: ... Increase ecosystem productivity; each species in an ecosystem has a specific niche—a role to play. Support a larger number of plant species and, therefore, a greater variety of crops. Even if a single animal is cut from the biodiversity( ie. Extinct) the whole of the food chain will collapse
Threats to Biodiversity. The greatest threat leading to the loss of biodiversity is the human race. As our population grows together with our need for food, water, industry, transportation, and home comforts, it takes over natural ecosystems and replaces them with unnatural.
Identify locations of critical wildlife habitat for species at risk and the threats to these areas. Where possible, eliminate threats and maintain natural areas. Leave critical wildlife habitat undisturbed, especially nesting and denning sites. Promote wildlife use by setting up bird and bat houses. And reduce the no of cars and automobiles there are. Avoid usimg of plastic and toxic substances as it causes further harm to biodiversity.
In the its our fault thw animals are close to extinction or alredy extinct. The least we can so is help to conserve and preserve our beautiful and diverse biodiversity.

Examples of ovoviviparous animal
Answer:
sharks, rays, snakes, fishes, and insects
Explanation:
These ovoviviparous animals produce eggs, but instead of laying eggs, eggs develop inside the mother's body. The eggs are laid in the mother. After rocking, they stay in the mother for a while and feed there. Then the young are born live.
Ovoviparity is, therefore, a mixture of oviparous (animals that lay eggs) and viviparous (animals that develop in the mother’s body).

Answer:
I think it’s active transport
The laboratory setup would most likely be used to demonstrate the process of diffusion.
What do you mean by Laboratory?A Laboratory may be defined as a place where a variety of experiments may be performed depending on the work or projects it handles.
In this experiment, an artificial cell containing glucose and starch solution is dipped into the water containing a starch indicator.
The concentration of glucose or starch is found to be high in the artificial cell, hence, it removes the water or particles from the inside to the outside of the cell.
Diffusion may be defined as the movement of particles or matter from a region of high concentration to a region of low concentration.
Therefore, the laboratory setup would most likely be used to demonstrate the process of diffusion.

which set of characteristics below describes a carbohydrate?
Answer:
supplies energy and fiber
Explanation:
Carbohydrates are what provides the body with fast, immediate energy, vs fats which are long term energy.
Carbohydrates are the source of energy thus the molecules that are used here are the energy molecules in the process of food metabolism as well.
What is the best source of carbohydrayte ?It is the whole grains, fruits and vegetables.
Along with the proteins and fats there are carbohydrates that are one of these three main nutrients that are in the foods and drinks. Our body is breaking down into the carbohydrates into the glucose. Glucose or blood sugar is main source of the energy for our body's cells, tissues and organs.
The primary role of the carbohydrates is to supply out the energy to the all of the cells in body. Many cells are preferred as the glucose that are a source of the energy where the other compounds as the fatty acids. Certain cells such as red blood cells are only there to produce out cellular energy out from glucose.

Answer: The question is not complete, options are not given but here are the options from another websites.
a. sexual reproduction.
b. binary fission.
c. parthenogenesis.
d. budding.
The correct option is C.
Parthenogenesis.
Explanation:
lizards undergo a process in which their unfertilized eggs can develop into new individuals and the process is called parthenogenesis because parthenogenesis is a reproductive strategy that involves the reproduction of new organisms without undergoing fertilization or the production of new organisms from unfertilized eggs and these can be as a result of the lizard not able to undergo sexual reproduction which can be as a result of environmental factors. This process does not involve sexual reproduction.
