How could you determine the identity of a bacterium?
Answer:
THE RELATIONSHIP OF IDENTIFICATION TO BACTERIAL CLASSIFICATION AND NOMENCLATURE. In order to identify an unknown bacterial isolate, the characteristics of the isolate must be compared to known taxa.

Explain why the passenger pigeon,which was once the most abundant bird in north America,disappeared completely.
Answer with Explanation:
The "passenger pigeon" used to be North America's most popular bird. Their population even reached 3 billion (or even more). They always traveled together. Their decline in number was noted in the 19th century. People became interested in hunting them for food because they were relatively cheap and tasty . They were also a great source of protein. It was easy to hunt them down although they could fly very fast because their flocks were huge in number. Some people killed them because they didn't want the birds ruining their crops. Their nesting grounds were also disturbed, which ultimately drove them away from the forests. People were overkilling them, and this sped up with the advancement of technology. The number of pigeons killed outnumbered the newborn pigeons, and after decades of hunting them down, their number dwindled with the last one passing away in 1914.
What is Natural Selection? Give an example for Natural Selection for Survival.
Answer:
is the process in nature by which organisms better adapted to their environment tend to survive and reproduce more than those less adapted to their environment. For example, treefrogs are sometimes eaten by snakes and birds
Explanation:
It's sorta like adapting with extra steps.
Answer: Natural Selection
Explanation: Individuals in a species have variation or mutations.
These differences may either be helpful, such as a giraffe with a long neck, or unhelpful, such as a colour variance in a moth that makes them stand out to predators.
The individuals that are more suited to their environment will survive and breed, passing on their genes.
Those that are not suited will die and their genes will not be in the ‘gene pool’.
This is the survival of the fittest!
define magnification and cisternae?
Answer:
Magnification In general terms, it can be said that how big or small the image appears with respect to the object is called magnification of the object.
Explanation:
It is represented as the ratio of the height of the image to the ratio of the height of the object. Magnification is denoted as the letter 'm'.
Magnification is the process of enlarging the apparent size, not physical size, of something. This enlargement is quantified by a calculated number also called "magnification".
A cisterna refers to a flattened membrane disk that makes up the Golgi apparatus. A typical Golgi has multiple stacks of anywhere from 3 to 7 cisternae stacked upon each other like dinner plates.The cisternae also carry structural proteins important for their maintenance as flattened membranes and their stacking upon each other.

1.allows for fewer cell organelles

What is the role of deoxyribonucleic acid (DNA) in organisms?
Answer:
Deoxyribonucleic acid (DNA) is a nucleic acid that contains the genetic instructions for the development and function of living things. All known cellular life and some viruses contain DNA. The main role of DNA in the cell is the long-term storage of information.

Here are some of the tRNA molecules in Lucy's white blood cells. Let's see if tRNA #1 is carrying the correct amino acid for its anticodon.
Using the RNA Pairing Rules, find the correct codon for this tRNA's anticodon.
Anticodon
CCA
Codon
Amino Acid
RNA Pairing Rules
A ↔ U
G ↔ C
Answer:
For the tRNA anticodon CCA the corresponding codon is GGU, which codes for the amino acid Glycine (Gly).
Explanation:
Transfer RNA or tRNA is responsible for driving the right amino acid into protein synthesis, once the mRNA codon has been translated by the ribosome. It is for that reason that each mRNA codon must have a complementary tRNA anticodon.
The RNA pairing rules is that each nitrogenous base has a complementary base, so:
- Adenine is complementary with uracil A=U
- Cytosine is complementary with Guanine C=G
In this case, it can be seen that:
For the anti-codon: CCACodon: GGUAminoacid: GlyAnswer:
For Anticodon it's: CCA
Codon it's: GGU
Amino Acid it's: Glycine (but when typing in the box for Amino Acid I typed in GGU and it was correct so that's the answer for Amino Acid.)

How does a bird develop?
Answer:
All birds start their lives inside an egg. When some birds hatch from the egg they are covered in downy feathers, and they are able to run around and find their own food. Many ground-living birds, such as pheasants and ducks, develop in this way.

A lichen is an organism that structurally appears to be a single organism. But a lichen is actually two different organisms—a fungus and green algae—living together as one organism. The fungal partner derives its nutrition from the photosynthesizing algae. How does a lichen differ in its photosynthetic activity from Elysia chlorotica, the sea slug that’s considered to be a photosynthesizing animal?
A.
In lichens, the fungi photosynthesize on their own, while Elysia chlorotica forms a relationship with a photosynthesizing plant.
B.
In lichens, the relationship with the algae lasts throughout the life cycle, but in Elysia chlorotica, the relationship occurs only during the immature juvenile stage of the slug’s life cycle.
C.
Lichens can photosynthesize only because of the living algal partner, while Elysia chlorotica incorporates chloroplasts from algae into its cells.
D.
In lichens, the association between the fungi and algae is permanent, while Elysia chlorotica associates with a photosynthesizing organism only when it requires food.
Answer:
B. Cycle
Explanation:
Lichen performs photosynthesis with the assistance of an algal partner, but Elysia chlorotica incorporates the chloroplast from an algal partner, which is how lichens vary from Elysia chlorotica in this regard, hence option C is correct.
How does lichen photosynthesize?A process known as photosynthesis is one in which green plants and some photosynthetic algae produce their own food, glucose, using carbon dioxide and water in the presence of light.
Lichen is a symbiotic association between an algal component that produces food and a dominant partner fungus that gives the lichen its thallus form and fruiting bodies. A particular species of mollusc called Elysia chlorotica uses the chloroplast of an algal partner to carry out the photosynthesis process.
Therefore, Lichens can photosynthesize only because of the living algal partner, while Elysia chlorotica incorporates chloroplasts from algae into its cells, hence option C is correct.

Shock absorbers that is present between the building and the ground motion, able the building to remain upright during an earthquake. The shock absorbers has the ability to absorb all the disturbance produced in the building and for that purpose the building is safe.
Explain how mitosis maintains the chromosome number
of the original cells when forming new cells.
Relation between mitosis and chromosomes:
During mitosis, a cell duplicates all of its contents, including its chromosomes, and splits to form two identical daughter cells. Because this process is so critical, the steps of mitosis are carefully controlled by certain genes. As they move, they pull the one copy of each chromosome with them to opposite poles of the cell. When mitosis is not regulated correctly, health problems such as cancer can result.When a cell divides by way of mitosis, it produces two clones of itself, each with the same number of chromosomes.

If I wanted to prepare to run a marathon, what type of macromolecule would I want
to consume?
Answer:
Complex Carbohydrates
Explanation:
There are different types of macromolecules and they all have different purposes, but for a marathon carbs, specifically, complex ones would be best. This is because carbs are the main source of energy for the body. Additionally, unlike proteins, they allow for long-term energy; so you could run an entire marathon without running out of energy.
