What are the different parts of a bacteriophage? Where is the DNA stored in this virus?
Answer:
What are the differents parts of a bacteriophage?
The tailed phages have three major components: a capsid where the genome is packed, a tail that serves as a pipe during infection to secure transfer of genome into host cell and a special adhesive system (adsorption apparatus) at the very end of the tail that will recognise the host cell and penetrate its wall.
Where is the DNA stored in this virus?
Where is DNA stored in viruses?
The genome of most DNA-containing viruses that infect eukaryotic cells is transported (with some associated proteins) into the cell nucleus, where the cellular DNA is, of course, also found.

2. Natural selection is an example of a mechanism of
evolution. Does this mechanism produce a change in
individuals or populations? Explain!
Answer:
Populations
Explanation:
It cannot change individuals. This is because it happens over many generations. E.g. Peppered moths camouflage with bark. Black moths do not, so they are easily seen by predators. The black moths are eaten because they do not have a desirable trait for survival. The black moths cannot then pass on the trait for black wings to their offspring. However, the peppered moths can pass on their trait for peppered wings to their offspring. Overtime, the population of black moths will decrease and most of the population will have peppered wings. The trait for peppered moths will be present even after many generations and black moths will be rare.
Which step happens first in DNA replication?
Answer:
Initiation
Explanation:
The initiation of DNA replication occurs in two steps. First, a so-called initiator protein unwinds a short stretch of the DNA double helix. Then, a protein known as helicase attaches to and breaks apart the hydrogen bonds between the bases on the DNA strands, thereby pulling apart the two strands. As the helicase moves along the DNA molecule, it continues breaking these hydrogen bonds and separating the two polynucleotide chains (Figure 1).

Questions about natural selection
Answer:
c is just wrong because that is not how evolution works evolution is a small change in the DNA that takes a long time through many many generations not just as you or an organism get older and smarter you are not evolving

Explanation:
Fungi form lichens by living in a close
relationship with an algae. The fungus provides a
protective home for the algae, and gathers mineral
nutrients from rainwater and from dissolving the
rock underneath. The algae gathers energy from
the sun using photosynthesis. Both organisms
share their nutrients with each other.
A. Commensalism
B. Parasitism
C. Mutualism
D. Competition
Answer: Commensalism
Explanation: Well you can already eliminate parasitism because that is when an organism leeches off another. Mutualism is when one organism needs to depend on another compared to A where both are benefited. Then you can eliminate d because competition is when two organism compete with each other for survival not benefiting them both.

E. include genes that determine an individual's sex.

The weather today will be like the weather tomorrow.
B
Knowing the climate makes it easy to predict the weather.
C
If it is cold today, you almost certainly live in a cold climate.
D
Weather can change quickly, but climate changes slowly.
E
The climate in the desert is highly variable.
Weather is all around us. It is what happens from minute to minute. Rain and snow are examples of weather. Climate, on the other hand, is quite different. Climate is the pattern of weather experienced over a long period of time in a certain area. A region that has high temperatures over many years has hot climate. Knowing the weather can help you choose what to wear today. Knowing the climate can help a farmer choose what crops to plant.
Answer:
B . Knowing the climate makes it easy to predict the weather.
C . If it is cold today, you almost certainly live in a cold climate.
D . Weather can change quickly, but climate changes slowly.
Explanation:
If we know the climate of a particular region we can predict the weather of the next day or week of that region because climate is remain the same of a specific region. If the weather is cold it means that you live in a cold climate, similarly, if the weather is warm it means the climate of that region is warm and hot. Weather can change and has high variations whereas climate is the average atmospheric conditions of a region for a long period of time.
How do the internal structures of the tree function together to help a tree take in and lock up carbon atoms from carbon dioxide in the wood of the tree as it grows?
Answer:
CO2 is a basic element for plants because it is a key part of their nutrition. They take carbon dioxide from the atmosphere and, after the process of photosynthesis, break down the gaseous molecule to supply themselves with energy, release oxygen and incorporate carbon atoms into their tissues. The trees of the planet act as a sink, sequestering CO2 from the air and fixing carbon for hundreds of years in the form of wood. Carbon will be released after the tree dies, when it begins to decompose.The inner layer called phloem or bast , is made up of living cells and its function is to conduct the sugar-filled sap from the leaves to the rest of the tree.
Explanation:
Trees, through photosynthesis, retain CO2 that they keep in their "organism" throughout their life cycle until they decompose. In this way they convert carbon atoms in the atmosphere into glucose (what they use to grow), and exhale oxygen that they release into the environment. By photosynthesis, plants retain CO2, becoming its dry mass of 50% carbon. The CO2 that is produced inside the mitochondria during respiration ends up being released into the atmosphere after crossing multiple barriers. The CO2 emitted by a stem xylem parenchyma cell must first cross the membranes and cell wall; and once in the intercellular spaces of the trunk, it does not diffuse rapidly outwards, but is slowed down by the conductive elements of the xylem and by the cambium, the phloem and, finally, the outer cortex. In the xylem, the arrangement and structure of the conductive elements, as well as the structure of the membranes of the pits that connect the conductive elements and these radially with the parenchyma influence the permeability to the passage of CO2.

How do the properties of water help it to shape the Earth ?
Answer:
Water moving across the earth in streams and rivers pushes along soil and breaks down pieces of rock in a process called erosion. The moving water carries away rock and soil from some areas and deposits them in other areas, creating new landforms or changing the course of a stream or river.

What do urchins eat?
Answer:
"Most representatives of this species are omnivorous. Sea urchins eat a variety of algae, mollusks, sponges, carrion, as well as starfish and sea urchins of smaller size. Some representatives of this species are known for the power to catch and eat a mantis cancer."
Explanation:
I looked it up
Answer:
Sea urchins mainly eat algae, but some also eat seaweed. When their average food is unavailable, like lots of animals at the moment, they will resort to trying new foods, like animal remains, sea cucumbers, mussels, sponges, brittle stars, crinoids, etc.

TACATCCATCAGTTACGC A guanine replaced the 1st Thymine in the original DNA strand above, how many amino acids would be changed as a result?
Answer:
One amino acid
Explanation:
This question is describing the occurrence of the process of mutation, which is the alteration in the genetic sequence of a gene. In this question, a DNA sequence was given as follows: TAC-ATC-CAT-CAG-TTA-CGC. However, a SUBSTITUTION MUTATION took place in such a way that the thymine base was replaced by a guanine base to have mutated sequence: GAC-ATC-CAT-CAG-TTA-CGC.
Since the mutation is a kind of substitution mutation, only the codon affected by that mutation will change. This DNA sequence will be transcribed into a mRNA sequence. The mRNA will be read codon by codon (a group of hree nucleotides) to produce amino acid. Since one codon will be involved, one amino acid will be affected.
