Given what you know about genetics and molecular biology, describe another way you might be able to identify specific bacteria
Answer:
Morphology
Explanation:
Bacteria are usually identified by using standard molecular biology procedures, being the Polymerase Chain Reaction (PCR) the most widely used technique for this purpose. The identification by PCR consists of the amplification and visualization of specific DNA sequences that can be obtained from different individuals, strains, species, etc. However, it is also possible to identify bacteria with a microscope, i.e., by observing taxonomical characteristics that allow to differentiate specific bacteria.

Select the living organisms that will decrease as a result of the loss of coral in the food web.
Answer:
Butterfly fish, Triggerfish, parrotfish, and sharks
Explanation: Because the first three fish listed feed on coral, their populations will decrease if coral is eliminated because that means there will be less food to go around for the populations to consume. Many will die out. If those fish die, there will be less of them for the sharks to eat, causing the shark population to decrease as well.

What events occur during high tide
Answer:
The tidal force causes Earth—and its water—to bulge out on the side closest to the Moon and the side farthest from the Moon. These bulges of water are high tides. As the Earth rotates, your region of Earth passes through both of these bulges each day. When you're in one of the bulges, you experience a high tide.

Do the hawaiian honeycreepers provide evidence to support Darwin’s theory of evolution by natural selection ?
Answer:
Yes.
Explanation:
This kind of bird, that is found at the islands of Hawaii have different kinds of beak. The adaptive radiation of those birds resulted on specialized forms of beaks and also, according to the Darwin natural selection theory, an ancestor of those birds probably had one kind of beak, but the different niches in the archipelago of Hawaii has selected different forms of beak leading to the actual species.
Yes, Hawaiian honeycreepers provide strong evidence that supports the Darwin's theory of natural selection.
Darwin's theory of evolution by natural selection:Hawaiian honeycreepers support the Darwin's theory of natural selection as different species of honeycreepers are adapted to fit into distinct surroundings. They are the endemic species, which inhabit the Hawaiian archipelago similar to the Darwin's finches that inhabited the Galapagos Islands.
The honeycreeper species of Hawaii has evolved the shape of their beaks in an efficient way in order to consume the nectar of distinct kinds of flowers on each of the Island. The beak shape of the honeycreepers fit to the flowers so that distinct species of bird can draw nectar more effectively based on the flowers found on each of the Island.
The species of Hawaiian honeycreepers demonstrate a good example of evolution by natural selection, that is, distinct species of the bird inhabit distinct islands in order to adapt with the specific environmental conditions.
Thus, it can be conclude that Hawaiian honeycreepers offer strong evidence to support the Darwin's theory of evolution by natural selection.

HOPE IT HELPS : D
Explanation:
d) A student suggested that purple flowers are more likely to be visited by bees than white flowers.
Use your knowledge of natural selection to suggest how this might affect the number of purple and white flowers in the wild.
Answer: the purple flower is very attractive than the white flower
Explanation:
As more bees visits the purple flower there is less competition between the white.flowers. And as more purple flower is used by the bees the population of purple flower decreases and of the white flowers increases..

Notice in the image of the plant that both oxygen and carbon dioxide enter and exit the plant. Using what you know about photosynthesis and cellular respiration, explain what is happening with regard to these two gases.
A) Unlike animals, plants use carbon dioxide in cellular respiration and produce oxygen.
B) Plants, as autotrophs, only undergo photosynthesis and both use and produce oxygen and carbon dioxide in this process.
C) Plants require oxygen for photosynthesis and produce carbon dioxide. Plants then use the carbon dioxide produced in cellular respiration, releasing oxygen as a byproduct.
D) Plants require carbon dioxide for photosynthesis and produce oxygen as a byproduct. Plants then use the oxygen released in cellular respiration, producing carbon dioxide as a byproduct.
Answer:
D
Explanation:
Plants first go through photosynthesis, using sunlight and carbon dioxide. This creates glucose. It then releases oxygen into the atmosphere as a byproduct. To convert the glucose into usable energy, the plant goes through cellular respiration, which converts oxygen and glucose into ATP.
The intructions for building proteins necessary for all like functions are coded within an organism's genetic code. The genetic code of an organism consists of codons, or sequence of three nucleotides, that each code for a specific amino acids. Amino acids are the building blocks of protein.
Answer:
This statement is true
Explanation:
The genetic code is required for the production of proteins with exception of some few mitochondrial proteins. The transfer RNA (tRNA) acts as an adaptor that enables to associate a messenger RNA trinucleotide sequence (known as anticodon) with its corresponding amino acid in the polypeptididic chain. The genetic code is considered to be a biochemical system capable of revealing the information contained in the DNA in order to synthetize a protein, which has been encrypted in the form of three nucleotides (i.e., codons).

Why do land plants need to conserve water
Answer: Some arid-climate plants are able to conserve water because of their reduced leaf size. Less leaf surface area results in reduced water loss through the epidermis. Small leaves have fewer stomata than larger leaves, and that adaptation also reduces water loss.
Because the fish are now able to swim in deep water, their ___________ in shallower water will have less food. Likewise, competition for food among deep-water fish that eat the same types of food will _____________.
Answer: Predators, increase
Explanation:
Because the fish are now able to swim in deep water, their Predators in shallower water will have less food. Likewise, competition for food among deep-water fish that eat the same types of food will increase.
Predation is the biological term used to describe the interaction between organisms whereby one organism which is a Predator kills and devour another organism which is its prey.
In shallow waters, Fishes are more susceptible to predators like man, eagle etc who catch and kill them and because of that many of these fishes have acquired anti--predator adaptations to prevent being caught and killed and so are now able to swim in deep waters leading to the predators having less food. The fishes who can now swim deep into waters will increase the already populated deepwater and will cause an increase in competition for the fishes that eat same type of food with the new fishes
