In a population of 100 people, 30 have brown hair and 70 have black hair. What is the Relative Frequency for Black hair?
Answer:
0.7
Explanation:
Given that in statistics, the Relative Frequency is the Frequency of the class divided by Total.
Hence, in this case, the Relative Frequency of black hair is the Frequency of black hair divided by the Total.
Hence, we have 70 ÷ 100
=> 0.7
Therefore, the correct answer is 0.7 Relative frequency.

Compared to the inertia of a 1-kilogram mass, the
inertia of a 4-kilogram mass is
A. 16 times as great
B. 1/16 as great
C. 1/4 as great
D. 4 times as great
please help.
Answer:
D. 4 times as great
Explanation:
The inertia of an object is the resistance offered by the object to change in its motion or position.
Then concept of inertia is obtained from Newton's first law of motion which states that an object which is not subjected to any net external force will remain its position of rest or constant velocity of motion until some net external force acts on it. The object at rest will then start to move whereas the object moving at constant velocity will experience a change in its speed or direction of motion.
This reluctance to change position is greater, the more massive an object is as well as the higher the speed of motion of the object. Thus, inertia is directly proportional to the mass of the object as well to the velocity of an object in motion.
From Newton's first law, inertia can be calculated as the force to be overcome to mobile an object, i.e. Inertia = F = ma
Where m is mass of object, a = acceleration of the object.
Objects on the earth's surface experience a constant acceleration, g.
Thus for a 1 kg mass, Inertia = 1 × g
For a 4 kg mass, inertia = 4 × g
The inertia of a 4 kg mass is four times as great as a 1 kg mass.
The inertia of a 1-kilogram mass, the inertia of a 4-kilogram mass is - D. 4 times as great
Inertia is the property of matter that resists changes in motion. Mass is the quantitative matter of motion.
Mass is that quantity that is solely dependent upon the inertia of an object.The more inertia that an object has, the more mass that it has.A more massive object has a greater tendency to resist changes in its state of motion.Thus, the inertia of a 1-kilogram mass, the inertia of a 4-kilogram mass is - D. 4 times as great.

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

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.

What is NOT an adaptation that pioneer species need? *
A. ability to do photosynthesis
B. live without soil
C. the ability to grow tall
D. tiny roots to break down rock
Explanation:
Primary succession, type of ecological succession (the evolution of a biological community’s ecological structure) in which plants and animals first colonize a barren, lifeless habitat. Species that arrive first in the newly created environment are called pioneer species, and through their interactions they build a simple initial biological community. This community becomes more complex as new species arrive. Primary succession is distinguished from secondary succession, which is the recovery of an existing biological community after a disturbance sets back the community’s ecological structure to an earlier stage.

Assume you saw biofilm formation on the negative control slide. What could account for such an observation? A You left the slide to incubate for too long. B The crystal violet dye was contaminated. с You used non-sterile slides or filter paper.
If biofilm formation is observed on the negative control slide, it could be due to either leaving the slide to incubate for too long (Option A) or using non-sterile slides or filter paper (Option C).
In biofilm experiments, the negative control is expected to show no biofilm formation since it does not contain the target microorganisms or conditions necessary for biofilm growth. If biofilm is observed on the negative control slide, it suggests that something went wrong during the experimental procedure. Option A suggests that the slide was left to incubate for too long, allowing unintended microbial growth and biofilm formation. Option C suggests that non-sterile slides or filter paper were used, introducing microorganisms or contaminants that can form biofilms. Both scenarios result in the presence of biofilms on the negative control slide, indicating a procedural error or contamination issue.

A.phototropic and gravitropic
B.thigmotropic and gravitropic
C.phototropic and influenced by ethylene
D.gravitropic and influenced by ethylene
Answer:
The correct answer is - A. phototropic and gravitropic.
Explanation:
A plant seedling grows usually two-direction shoots or stems towards light and roots towards the soil or in the direction of gravity. The movement of the plant toward a specific stimulus or effect parts is called tropism and different parts move in a different direction.
The movement of the roots of the plant is usually towards the direction of soil or gravity and this is called gravitropic. The shoot or stem grows from the seedling towards the direction of light and it is called phototropic.

does this an suggest evolutionary relationship? explain how these embryos can be used as evidence of a common ancestor between each of these six organism
Answer:
Examination of vertebrate embryos reveals that during corresponding stages of early development,
the embryos appear to be very similar. For example, all vertebrate embryos pass through stages in
which they have gill pouches. The pouches eventually develop into the gill apparatus in fish; in laterevolving vertebrates that do not have gills, the gill pouches undergo further refinement and develop
into structures associated with the head and neck. Similarly, all early vertebrate embryos have tails,
which persist in some animals but regress during the later stages of development of humans. Thus,
the individual development of an animal occurs through a series of stages that paint a broad picture
of the evolutionary stages (phylogeny) of the species to which it belongs.
"Ontogeny recapitulates Phylogeny", Haeckel
Explanation:
sure po ito
Examination of vertebrate embryos well-known shows that in corresponding levels of early improvement, the embryos appear very similar.
For example, all vertebrate embryos by skip thru levels in which they have got gill pouches. The pouches subsequently turn into the gill equipment in fish; in later evolving vertebrates that don't have gills, the gill pouches go through similar refinement and develop into systems related to the pinnacle and neck. Similarly, all early vertebrate embryos have tails, which persist in a few animals however regress at some point in the later levels of improvement of humans.What is ontogeny recapitulates phylogeny?These scientists claimed that ontogeny recapitulates phylogeny (ORP). This word shows that an organism's improvement will take it thru every one of the personal levels of its evolutionary history, or its phylogeny.
Thus, the man or woman improvement of an animal happens thru a chain of levels that paint an extensive picture of the evolutionary levels (phylogeny) of the species to which it belongs.

Connell’s results led him to conclude that Chthamalus’ realized niche is smaller than its fundamental niche because of interspecific competition with Balanus. But what if competitive exclusion were not the explanation? What if Chthamalus’ and Balanus’ respective niches were a result of niche differentiation instead? Niche differentiation occurs when two species with overlapping niches change over time in a way that reduces their niche overlap, and thus reduces their competition for resources.
Answer:
Both realized niche and fundamental niche are similar in size.
Explanation:
If Chthamalus’ and Balanus’ respective niches were a result of niche differentiation so we can say that Chthamalus’ realized niche is not smaller than its fundamental niche. It will be of the same size because of no interspecific competition with Balanus. The whole fundamental niche is considered the niche of the Chthamalus' alone due to no competition with Balanus' for resources present in the ecosystem.

For the 2nd one with the bear: Thick coats on a bare will help provide warmth whenever they go to hybernate. Thin fur would leave room for freezing and wouldn't be able to help them maintain the proper body temperature.
The 3rd one with the clownfish: A round tail provides a bigger boost when swimming since it is able to push more water. A forked tail would create a gap when they swim so they would have to expend more energy than with a round tail.
