Traditionally, zoologists have placed birds in their own class, Aves. More recently, molecular evidence has shown that birds are

more closely related to reptiles than their anatomy reveals. Genetically, birds are more closely related to crocodiles than crocodiles are to turtles. Thus, bird anatomy has become highly modified as they have adapted to flight, without their genes having undergone nearly as much change. Taxonomically, what should be done with the birds?
A: The rest of the reptiles should be reclassified as a subclass within the class Aves.
B: Birds should be reclassified, and their new taxon should be the subclass Aves. Genetic similarity trumps morphological dissimilarity in cases where morphological traits are uninformative.
C:The classification scheme should remain the same because of historical precedence.
D: The traditional stance is correct. Such dramatic morphological change as undergone by birds indicates that birds should be placed in their own order, separate from the reptiles.

What does Donor means in coordinate​
Roman55 [17]

Answer:

Donor coordination is meant to counteract this and has become an important item on the international development agenda.The underlying reason for this is the growing pressure to improve the efficiency and effectiveness of development cooperation exerted, on the one hand, by the ambitious Millennium Development Goals (MDGs) and the comprehensive poverty reduction strategies being pursued by many low-income countries and, on the other hand, by scarce development cooperation resources.

a. The logistic equation reflects the effect of density-dependent factors, which can ultimately stabilize populations around the
castortr0y [4]

Question:

Which of the following is an incorrect statement about the regulation of populations?

Answer:

b. Density-independent factors have an increasingly greater effect as a population's density increases.

Explanation:

A population can be defined as the total number of living organisms living together in a particular place and sharing certain characteristics in common.

Generally, these populations may be divided into a fraction of the population (subpopulation) based on certain factors and reasons.

Population change equation states that the change in the size of a population over a specific period of time is equal to the sum of the number of births and the number of immigrants that joined.

Mathematically, the population change equation is given by the formula;

Population Change = (Natality - Mortality) + (Immigration - Emigration)

Population regulation can be defined as a biological process that balances limiting factors affecting the growth of a population based on density. The factors that regulate the growth of a population are divided into two (2) main categories and these includes;

I. Density-independent factors.

II. Density-dependent factors.

Density-dependent are regulating factors such as predation, diseases, and competition that affect the size of the population of living organisms through decreasing or increasing mortality and birth rate.

Furthermore, density-independent factors do not have an increasingly greater effect as a population's density increases. Thus, its effect are reduced as a population's density increases in size.

In the 1950s, when Watson and Crick were working on their model of DNA, which concepts were well accepted by the scientific comm
julia-pushkina [17]

Answer:

Option (1), (2) and (3).

Explanation:

DNA is the genetic material of all the living organisms present on earth. The DNA contains the nitrogenous bases, pentose sugar and the phosphate group. DNA strands runs in the opposite direction and shows polarity.  

Watson and Crick explain the structure of DNA based on the X ray diffraction produced by Rosalind. According to the structure, chromosomes are present in the nucleus and contains the DNA and wrapped around the proteins. The genes is considered as the functional segment of DNA.

Thus, the correct answer is option (1), (2) and (3).

using the gas pedal analogy explain the impact on the cell cycle of a proto-oncogene versus an oncogene
rusak2 [61]

Using the gas pedal analogy, the proto-oncogene would be an accelerator since they promote cell division and deregulate apoptosis, while tumor suppressor would be the brakes since they constrain the progress of the cell cycle and induce cell apoptosis. An oncogene is, therefore, when the accelerator is stuck in down position and the brakes are not working.

Create an explicit equation for each recursively-defined sequence below.
lbvjy [14]

Answer:

  t(n) = 3·5^(n-1)

Explanation:

The recursive formula describes a sequence in which each term is 5 times the one before it. This is a geometric sequence with common ratio 5 and a first term that is said to be 3.

As you know, the generic formula for a geometric sequence is ...

  an = a1·r^(n-1)

For a1 = 3, r = 5, and a sequence named "t", this is ...

  t(n) = 3·5^(n-1)
