At which classification level could two organisms belonging to the same group have the LEAST
in common?
class
family
order
species
Explanation:
Species but dot take my word on it is was an educated guess
Answer:
Explanation:
Species
kingdom is further split into phylum or division, class, order, family, genus, and species, which is the smallest group.
The science of classifying organisms is called taxonomy and the groups making up the classification hierarchy are called taxa.
The law of conservation of energy states that energy cannon be created or destroyed.
O True
O False
Answer:
false
Explanation:
The first law of thermodynamics, also known as Law of Conservation of Energy, states that energy can neither be created nor destroyed; energy can only be transferred or changed from one form to another. For example, turning on a light would seem to produce energy; however, it is electrical energy that is converted.

Which components bond with andenine in a section if double stranded DNA
Answer: 3 and 5 only
Explanation:
Adenine is a purine nitrogenous base and it pairs with thymine which is a pyrimidine nitrogenous base with a triple hydrogen bond in a DNA structure. The adenine binds with thymine directly and indirectly with a deoxyribose sugar which is attached with it in the back it forms the part of sugar phosphate backbone and in the front hydrogen bonding helps in the stabilizing the DNA structure by binding two separate strands of DNA in a stable double helical structure.

Describe an adaptation to a plant's life cycle and explain how this adaptation helps the plant survive. Source StylesNormal
Answer:
The adaptation of a plant in an environment ( for example,desert) depends on the structural parts of the plant which enables it to complete it's life cycle.
Explanation:
Plants are found in different types of environment. They need to possess and show some features that will enable them to live successfully and reproduce in that particular environment. Such features may be structural, functional or behavioural which are known as ADAPTATIONS.
Furthermore, in environment where there is scarcity of water supply, plants known as xerophytes can survive or thrive. They show the following adaptations:
--> well developed roots: the roots grow down to great depths if necessary and branch extensively in order to absorb water from as large an area as possible.
--> presence of swollen stems: These stems contains water storage cells which are called succulents. They help the plant withstand long period of drought.
--> Reduced leaves: This helps in reducing water loss from leaves through transpiration. For example in plants like the cacti, the leaves are reduced to spines.
Therefore, these structures helps the plant survive in its present environment.
The primers you used in lab amplified 145 base pairs that were adjacent, but not included in the repeat. If you used a different primer that only amplified 130 base pairs adjacent to a 14 base pair repeat, and you had 4 repeats in your product, what was the size of your final PCR product?
186
214
158
200
172
Answer:
186
Explanation:
The Polymerase Chain Reaction (PCR) is a technique used in molecular biology to amplify small segments of DNA. This technique uses a pair of oligonucleotide sequences called 'primers' which bind to opposite strands of the heat-denatured DNA template in order to amplify this target DNA sequence. In this case, the DNA template is composed of a single unit of 130 base pairs (bp) and four repetitive units of 14 bp, so the final PCR product will have 186 bp >>> 130 bp + (14 bp x 4) = 130 + 56 = 186.

Answer:
For Desssert: C
For Taiga: A
For Tropical Rainforest: B
Explanation: Because desserts are very hot, we know that there aren't much plants due to the lack of rain/water, they're dry. Rainforests have lots of plants, so it's not B, and since the dessert is high temperature, A is obviously off the list.
Taiga is cold so it won't be good for soil and the plants won't grow as good as the wet rainforest so we can pick A. Then B for #2
Innate immunity and acquired immunity are both _____. See Concept 43.1 (Page 953) View Available Hint(s) Innate immunity and acquired immunity are both _____. See Concept 43.1 (Page 953) dependent on surface secretions from sebaceous and sweat glands, which give the skin an acidic pH that is unfavorable for bacterial colonization based on the trapping of microbes by mucus dependent exclusively on cell-mediated responses characteristics of all vertebrate animals dependent on tears, saliva, and mucous secretions that contain lysozyme, an enzyme that digests bacterial cell walls
Answer:
The correct answer is - characteristics of all vertebrate animals.
Explanation:
Innate immunity is the first line of the immune system that comes with birth whereas adaptive or acquired immunity is the immunity that comes throughout life by experiencing or developing the immune system. Adaptive or acquired immunity is the immune response that comes through cell-mediated responses whereas innate immunity is the immune response that includes sweat glands and secretion from the skin. innate immune responses also include digesting and killing bacteria by the saliva, enzymes, lysozymes.
The only characteristic among these that present in both is that they both immune systems found in all vertebrates.

Mutualism is a symbiotic relationship in which both organisms benefit.
Parasitism is a symbiotic relationship in which one organism benefits and the other organism is harmed.
Predation is a relationship in which one organism preys on (and eats) another organism.
Competition is relationship in which two organisms must fight (directly or indirectly) for resource
Objective:
Given a description of the relationship between two organisms, determine if their relationship is competition, commensalism, predation, mutualism, or parasitism.

11. Mycorrhizal Fungi and Plants: The mycorrhizal fungus grows into the roots of some plants and gets nutrients from the plant. The fungus helps the plant absorb inorganic nitrogen and phosphorus from the soil. Some fungi also secrete antibiotics, which can help protect the plant from parasitic fungi and bacteria. _______________________________

3. Compare and contrast the movement produced by each of the three types
Answer:
strike-slip is when the blocks have mostly moved horizontally, normal is when a dip-slip fault in which the block above the fault has moved downward relative to the block below, and thrust is when the hanging wall moves up relative to the footwall.
There are three faults. Normal faults originate from the divergent boundary. Reverse faults originate from the convergent boundary. Strike-slip fault originate from transforming boundary.
What are the three types of fault?We can differenciate three types of faults,
Normal fault ⇒ originate from divergent movementReverse fault ⇒ originate from convergent movementStricke-slip fault ⇒ originate from transforming movementWhat are the boundary types?I. Divergent:
This boundary occurs when two plates separate and molten material rises from the mantle creating a new crust.
The hot material creates a new seabed between the separating plates, expanding the sea bottom.
II. Convergent.
Collision area between two plates. Two oceanic plates might collide, or one oceanic plate with a continental one.
In this last case, the oceanic crust sinks under the continental plate, and magma rises to the surface by crevices.
The thicker and older plate subduces under the other plate.
III. Transforming.
The plates slide laterally with each other, and they are usually called faults.
It is associated, in general, with the oceanic ridge, although it might also occur in the continental plate.
No rocky material is either destroyed or formed.
When the plates move and produce a displacement of one transforming limits from side to side, earthquakes occur.
The movement breaks the crust and originates pronounced fractures.

Once anything passes through the event horizon, from the perspective of that
object, nothing would change.
True or false
Answer:
True
Explanation:
The event horizon of a black hole is where gravity is such that not even light can escape. This is also the point I understand that according to Einstein time dilation will be infinite for a far-away-observer.
The statement "once anything passes through the event horizon, from the perspective of that object, nothing would change" is true.
What is horizon?The horizon would be the line that appears to divide a celestial body's ground from its own sky when observed by an observer standing on or close to the body's surface.
What is event?An event would be the collection of results from an experiment.
Therefore, the statement "once anything passes through the event horizon, from the perspective of that object, nothing would change" is true.
