Using its long tail and long hind legs, the Ord's kangaroo rat can jump 2 m in the air as it hops away from predators, such as snakes and owls [A, 4 marks] a. How would Lamarck account for the origin of the long hind legs of the Ord's kangaroo rat? b. How would Darwin?

Answers

Answer 1

Answer and Explanation:

a. According to Lamarck, the origin of the long hind legs of the Ord's kangaroo rat is acquired due to extensive use of the muscle legs to jump. Such physical characteristics could be transmitted to future generations. This theory is called Neo-Lamarckism.

b. Darwin, on the other hand, theorized that in a population of Ord's kangaroo rat, there was an individual whose characteristics, long tail and hind legs, had more chances of escaping its predator and, consequently, could survive and reproduce. This theory is called Darwinism.

What is a niche, and how does it relate to evolution?

Answers

Answer:

The evolution of species’ niches is a process that is fundamental to investigations in numerous fields of biology, including speciation, community assembly, and long-term regional and global diversification processes. It forms the nexus between ecological and evolutionary questions. Topics as diverse as ecological speciation, niche conservatism, species coexistence, and historical biogeography all rely on interpreting patterns and drivers of species’ niches through time and across landscapes. Despite this importance, a distinct research agenda concerning niche evolution as a discrete topic of inquiry has yet to emerge. Niche evolution is often considered as a sidebar or of secondary importance when addressing questions such as “how did two species diverge?” Basic questions such as “what is a niche,” “what is the biological basis of niche evolution,” “at what scale should we evaluate niche evolution,” and “how can we observe niche evolution at different timescales” have rarely been addressed directly, or not at all in some systems. However, various intellectual threads connecting these ideas are evident in a number of recent and historical publications, giving some semblance of form to a framework for interpreting and evaluating niche evolution, and outlining major areas for future research from an evolutionary perspective. There is a reverse perspective from the macroecological scale as well, with questions involving coexistence, distributions and ranges, food webs, and other organismal attributes

Sulfur has 16 electrons in its atoms. Over how many energy levels are the electrons distributed, and how many are in each energy level? The electrons in a sulfur atom are distributed over the three energy levels; there are two electrons in the first energy level, eight in the 2nd, and six in the third.

Many new reproductive strategies developed during the evolution of terrestrial vertebrates. Which statement identifies one of these new strategies? A. Eggs develop without fertilization B. Eggs develop outside of a parent's body C. Eggs are laid by the female parent only D. Fertilized eggs develop away from the body of water

Answers

Answer:

D

Explanation:

One of the reproductive strategies of terrestrial vertebrates is the ability of fertilized eggs to develop away from the body of water.

Water is very important for fertilization in aquatic organisms and one of the biggest challenges posed by migrating to the terrestrial environment is desiccation of the eggs. Terrestrial vertebrates are able to overcome these challenges by making fertilization of eggs internal and the ability of the fertilized eggs to develop away from the body of water.

The correct option is D.

Answers

Answer:

On the left is negative charge while on the right is positive charge.

Explanation:

On the left, there should be negative charge that will move away due to repulsion force because both charges are same so they move away from one another while on the other hand, on the right side there should be positive charge which will move towards it because both charges are opposite to each other so they attract each other.

Answers

Answer:

Explanation:

The phenotype, similar to the genotype, can be observed in two senses: wider and narrower. In a broader sense, a phenotype is a set of all morphological and physiological properties by which an organism is recognized and by which it differs from other organisms.

When we look at only one trait, then it is the narrower meaning of the phenotype. What will be the influence of genotype on phenotype depends not only on the genetic basis but also on the action of environmental factors in which the organism develops.

strength

NEXT QUESTION

READ NEXT SECTION

ASK FOR HELP

TURN IT IN

Answers

Answer:

The property that makes steel a good choice for sword-making is strength

Explanation:

The strength of a material is its ability to withstand an applied load or force without failure or plastic deformation.  Types of strength of materials include; tensile strength, yield strength, torsional strength, compressional strength, shear strength.

Tensile strength of material is the ability of that material to withstand any force that tends to break or tear it apart. It is calculated by dividing the maximum amount of load or force the material can carry or withstand without breaking by the surface area of the material.

Mathematically, Tensile strength = Force/area

Its unit is Newton per meter squared, N/m².

Yield Strength In Steel

Yield strength is the maximum stress that can be applied before it begins to change shape permanently. Yield strength represents the upper limit of the load that can be safely applied to the meta beyond which it shape deforms.

Steel is an alloy of iron and carbon. It has many important and desirable properties such as durability, hardness and conductivity, and high tensile strength. However, the high strength of steel made a good choice for sword-making in the ancient past and even in the present.
