Answer:

1 adaptation of carnivorous plant is this

Trapping Their Prey

Common trapping techniques are pitfall traps, flypaper traps, snapping traps, and suction traps. The first two use adaptations that involve shape and sticky surfaces. The last two are particularly fascinating, because the presence of prey triggers the plant to take action — to move, quickly!

kobusy [5.1K]

<u>Answer:</u>

<em>The biologists clarify these similarities as a homologous pair. This is based on the principle of convergent evolution.</em>

<u>Explanation:</u>

<em>Convergent evolution</em> is understood by the phenomenon of development of similar organs in different species in different period. Those<em> homologous pair </em>have same structure but can have different function in the different <em>species of organism. </em>

The bone of human arms, wings of the bat and dolphin flippers contain many of same bones which have developed from the same embryo tissue but the function for each is <em>different in different species.</em>

Proto‑oncogenes are genes that have the potential to become oncogenes through either mutation or an increase in expression. Clas
algol [13]

Answer:

<u>Proto-oncogenes</u>

  • These genes code for protein that normally promote cell division
  • Mutations that increase activity of these genes may lead to cancer

<u>Tumor suppressor genes</u>

  • These genes code for protein that normally prevent uncontrolled cell division
  • Some products of these genes normally function in repairing damaged DNA
  • Mutation that decrease activity of these genes may lead to cancer.

Explanation:

<em>Proto-oncogenes</em> are group of genes that ordinarily help cells develop. At the point when a proto-oncogene mutates or there are such a large number of duplicates of it, it turns into a "terrible" quality that can turn out to be forever turned on or activated when it shouldn't be. At the point when this occurs, the cell becomes wild, which can prompt malignant growth. This terrible quality is called an oncogene.

Tumor suppressor genes are normal gene that hinder cell division, fix DNA missteps, or tell cell when to undergo apoptosis (die). At the point when tumor suppressor gene don't work appropriately or inactivated, cells can develop uncontrollable growth, that ultimately lead to cancer.

Which information is needed to construct a geomagnetic time scale?
AleksAgata [21]

Answer:

the magnetic direction of rocks along the surface of Earth and the age of rocks along the surface of Earth

Explanation:

The earth's magnetic field or geomagnetic field is believed to originate from the movement of molten iron and nickel in the outer core.

During a period in which the earth magnetic field is normal, crystallising magnetic minerals in magma records the orientation of the prevailing geomagnetic field. At other times when the field reverses and the magnetic field orientation changes, magnetic minerals in cooling magma stores this record.

To create a geomagnetic time scale, geologists can assign absolute ages to the records of these paleomagnetic anomalies which are the reversals. The rock is dated using radiometric techniques and each period of reversal is ascribed an absolute geologic age. Therefore, the magnetic direction of rocks along the surface of Earth and the age of rocks along the surface of Earth helps to build the geomagnetic time scale of the earth.

Consider the following hypothetical population and compute the statistical measures below: #births = 50,000; #deaths = 10,000; #
777dan777 [17]

Answer:

The birth rate refers to an average number of births in one year per thousand individuals in the population at mid-year.  

BR = (total birth in an annum / total population in mid year) * 1000

BR = (50000 / 1000000) * 1000 = 50

Death rate refers to an average number of death in an annum per thousand individuals in a population at mid year. Thus,  

DR = (total death / total population in mid year) * 1000

DR = (10000 / 1000000) * 1000 = 10

Annual population growth rate or APGR is calculated as:  

APGR = (Birth rate - Death rate) / Death rate

APGR = (50 - 10) / 10 = 4.0 %

Doubling time is the whole sum time needed for a population to get double in size. It is calculated as DT = ln (2) / growth rate

70 / 4.0 = 17.5 years

Thus, population will get double in 17.5 years.  

Adjusted (true) growth rate is equal to APGR + (NMR / Death rate)

And NMR = [(immigrants -emigrants) / total population] * 1000

NMR = [(5000 - 20000) / 1000000] * 1000 = -15

Thus, Adjusted (True) growth rate = 4.0 + (-15 /10) = -6%

The adjusted (true) doubling time = ln (2) / Adjusted growth rate  

= 70 / -6 = -11.66

This negative sign shows that it will never get double in such situation.

__________ is/are defined as a group of potentially breeding organisms within a species in a given space and time.
elena-s [515]

Answer:

Population.

Explanation:

Population may be defined as the smallest unit of ecology and the evolution might occur at the population level.

Population is the group of the organisms that belong to the particular species and lives in a specific particular habitat. The individual of the population breeds among themselves. Sometimes the individual of two different population can also breed among themselves in extreme cases.

Thus, the answer is population.
