Explanation:
Polar bears feed on seals. So, polar bears and seals share a . Climate change has caused ice caps to melt in colder regions where polar bears live. This change has caused them to hunt less. This situation will lead to .
Polar bears and seals are animals that share a prey-predator relationship, whereas climate change causes less biomass at the quaternary level.
What is the prey-predator relationship?The prey-predator relationship is s type of ecological association where one species is hunted (the prey) by another species.
Moreover, climate change is well known to produce global warming and melting ice on the Earth's poles.
In conclusion, polar bears and seals are animals that share a prey-predator relationship, whereas climate change causes less biomass at the quaternary level.

What might happen to the organisms in the food web below if the number of phytoplankton and vegetation drastically decreased?
Answer:
i don't now exactly how to answer this when theres' no food chart however as the vegetation and phytoplankton drastically decrease everything decreases. This is because the producer the bottom of the food chain also known as vegetation is the prime source of energy in every food chain. when there's scarce amounts of producers a domino affect will occur. There will be no food for the first consumers to eat leading their population to decrease and the animals that feed off them will decrease then the animals that feed of them will decrease and so on until the organisms of the food web die out.

Describe step by step, with your own words, the process of replication of a double strand of DNA.
Answer:
replication. DNA replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. Replication is an essential process because, whenever a cell divides, the two new daughter cells must contain the same genetic information, or DNA, as the parent cell.

Explanation:
Explain the effect of temperature and pH on enzyme action.
Needs to be done ASAP.
Answer:
enzymes loose their form in both unsuitable ph and temprature.
Explanation:
at very high tempratures enzyme molecules denatures due to high speed movements, at low tempratures enzymes works too slow to be useful enough.
low ph solotions contain lot of H+ and high ph solutions have few H+ , and the number of these H+ ions have polar effects on enzymes. some Enzymes like pepsin works perfect in acidic environment ( ph=2) while others might work at high ph or average ph( like Trypsin works well at ph=7).

A mining company is interested in monazite, a mineral substance that forms in igneous rock in Earth’s interior. They think they found a lot of monazite in a sedimentary rock formation at Earth’s surface. Could this really be monazite? If so, how could the monazite have become part of sedimentary rock?
Answer:
Yes, it could have been monazite.
Monazite could have become part of sedimentary rock because it is formed during the metamorphosim of clastic sedimentary rocks. It is a resistant minerals that is found in weathered rocks debris which become concentrated and they are part of the soils and sediments found near weathered rocks.
Explanation:
Monazites are phosphate minerals that are found im small grains as accessory in igneous rocks and sedimentary rocks. It is formed during the crystallization of igneous rock and metamorphosim of clastic sedimentary rocks.
It is a resistant minerals that found in weathered rocks debris and become concentrated in sediments near weathered rocks.

What is the end product of the process of respiration? *
A. glucose and oxygen
B. water and carbon dioxide
Answer:
B. carbon dioxide and water
Explanation:
Respiration is a process that animals and plants undergo to create energy to grow, move and sustain life.
The equation for cellular respiration is:
glucose + oxygen —> ATP + carbon dioxide + water
The organisms use glucose from food and oxygen to create ATP (useable energy), carbon dioxide and water.
Therefore, the answer is B. Carbon dioxide and water. Glucose and oxygen are not the end results, they are used to make the end results.
Answer:
B. water and carbon dioxide

mtDNA (mitochondrial DNA) analysis
Explanation: DNA fingerprinting technique is a laboratory technique used by geneticists.it entails placing of DNA samples into wells,these wells are then placed in a slab of gels and thereafter passing a current through the gel.This is done to ascertain the uniqueness of a DNA pattern and thus be able to differentiate people of same species.
There are several methods of DNA fingerprinting as outlined in the options given with the question.
In mtDNA (mitochondrial DNA) analysis,The Genetic samples are extracted from the biological materials, these samples extracted are total genomic DNA like hair,tooth or samples of blood, Several copies of these genomic DNA are then produced using a polymerase chain reaction and flanking primers inorder to examines the length variation of DNA repeat sequences in human DNA.

which statement best describes how genes are able to produce a organism's traits? A. Genes have versions called alleles, which produce different traits. B. Genes exit the nucleus and go to ribosomes, where proteins form. C. Genes contain codes that specify proteins, which produce traits. D. Genes unwind and become templates, where amino acids can line up.
Answer:
C
Explanation:
The genes contain codes that specify proteins, which produce traits.
Genes contain codes that specify proteins, which produce traits best describes how genes are able to produce a organism's traits.
What is a gene?Genes are segments of DNA that contain the instructions for making proteins, which are complex molecules that perform a wide variety of functions in the body. Proteins are made up of chains of amino acids, and the specific sequence of these amino acids is determined by the code contained in a gene. Different versions of a gene, called alleles, can produce different sequences of amino acids and therefore different proteins, which can lead to different traits in an organism.
Genes are found in the nucleus of cells, and the process of making proteins begins when a gene is transcribed into a molecule called RNA. This RNA molecule exits the nucleus and goes to ribosomes, which are the site of protein synthesis. At the ribosomes, the RNA molecule serves as a template for the synthesis of a protein, with the specific sequence of amino acids being determined by the code contained in the RNA molecule. The protein is then folded into its characteristic shape, which allows it to perform its specific function in the body.
