The term population dynamics would not be used to describe which of the following examples?
Α.
birth rates
B.
changes in population size
death rates
success of offspring reaching reproductive age
Answer:
Population size is influenced by the per capita population growth rate, which is the rate at which the population size changes per individual in the population. This growth rate is determined by the birth, death, emigration, and migration. Pretty much Birth rate or Death rate.

Which of the following IS
an example of reproductive isolation?
O two populations
of finches that cannot produce viable offspring
O two populations of finches that have different feather colors
• two populations of salamanders that live in different lakes
O two populations of salamanders that
have different tail lengths
An example of reproductive isolation is two populations of salamanders that live in different lakes. Thus, the correct option is C.
What is Reproductive isolation?Reproductive isolation may be defined as the inability of a species to interbreed successfully with related species members due to isolating mechanisms.
Reproductive isolation may leads to speciation. A single specie scan generates multiple species via reproductive isolation. The members of the same species undergo reproductive isolation due to several isolating mechanisms.
The isolating mechanisms include geographical, behavioral, physiological, or genetic barriers.
Therefore, the correct option for this question is C.

What characteristic do sea stars and brittle stars have in common?
Both have flexible joints.
Both have teeth-like feeding structures.
Both use tube feet to catch prey.
Both have tentacles.
Answer:
They typically have a tough, spiny surface, which inspired their name (in Greek, echinos means “spiny” and derma means “skin”). They also have the unusual ability to regrow lost body parts, and sea stars and brittle stars can regrow arms if broken off or eaten
Explanation:
Sea stars and brittle stars both use tube feet to catch prey. Therefore, option C is correct.
What are sea stars and brittle stars?Echinoderms with a star form that belongs to the class Asteroidea are known as starfish or sea stars. These terms are frequently used incorrectly to refer to ophiuroids, which are properly called brittle stars or basket stars in common usage. Due to their membership in the class Asteroidea, starfish are also referred to as asteroids.
The benthic (bottom-feeding) fauna of the maritime environment includes brittle stars. They belong to the Phylum Echinodermata, which includes marine organisms with radial symmetry, five components, and frequent spines. They are commonly referred to as echinoderms.
Sea stars and brittle stars both use tube feet to catch prey. Therefore, option C is correct.

An example of a nucleotide is?
A. cytosine, ribose, and deoxyribose
B. guanine, deoxyribose, and phosphate
C. uracil, deoxyribose, and phosphate
D. thymine, ribose, and phosphate
Answer:
B
Explanation:
A nucleotide always consists of 3 things:
1. A sugar group (either ribose or deoxyribose, ribose if the nucleotide is from RNA, deoxyribose if it is from DNA.
2. A phosphate group
3. A nitrogenous base (A/T/U/C/G) This base depends on whether you have RNA or DNA, U is only for RNA. DNA has either A/T or C/G but never U.

Explain how sexual and asexual reproduction both lead to better evolutionary fitness.
Answer:
Hope you get done. friend me back. and can I have brainliest
Explanation:
To get diversity in individuals, genetic differences are required, and different phenotypes must be expressed. Since sexual reproduction is more conducive to driving evolution than asexual reproduction, much more genetic diversity is available for natural selection to work on. Evolution can happen over time.

Suppose that the same island experiences environmental
conditions that prevent the growth of large seeds. What do you think would happen to
the average size of finch beaks? Explain your reasoning.
Answer:
The size of finch's beak depends on the size of seeds.
Explanation:
The average size of finch beaks also changes because the size of finch beak changes according to the size of seed available. If the environment contains large sized seeds so the population of finch having small beak size increases due to food availability while on the other hand, if the region contains large sized seeds so the population of finch having big beak size increases so according to the size of seeds, the size of finch's beak also changes.
4. What is an example of positive feedback?
a. Regulating blood glucose levels
b. Maintaining internal body temperature
c. Producing milk in nursing mothers
Answer:
C
Explanation:
It is known as lactation. The suckling action of an infant produces prolactin, which leads to milk production; more suckling leads to more prolactin, which in turn leads to more lactation. This is a positive feedback system as the product (milk) produces more suckling and more hormone. When the child is no longer breast feeding, the prolactin drops off and milk production goes down.

*EXTRA PTS* How much weight is needed for a 10 m high ball to achieve 400 J of potential energy?
Answer:
,Mass of the Body = 10 kg.
Height = 10 m.
Acceleration due to gravity = 9.8 m/s².
Using the Formula,Potential Energy = mgh
= 10 × 9.8 × 10 = 980 J.
(b). Now, By the law of the conservation of the Energy, Total amount of the energy of the system remains constant.
∴ Kinetic Energy before the body reaches the ground is equal to the Potential Energy at the height of 10 m.
∴ Kinetic Energy = 980 J.
(c). Kinetic Energy = 980 J.
Mass of the ball = 10 kg.
∵ K.E. = 1/2 × mv²
∴ 980 = 1/2 × 10 × v²
∴ v² = 980/5
⇒ v² = 196
∴ v = 14 m/s.
3. Yes - At maximum stretch the ball stops. The ball is now 2 meters plus x below the starting point where x is the stretch distance down. The total energy is all potential in the springs and gravitational and is m g (2 + x)
