The currently recognized classification scheme is the five - kingdom system.

The five kingdom classification involves the grouping of living organisms into classes such that organisms in each class share similar characteristics such as : reproductive process, homeostasis, growth, mode of nutrition, cell structure and so on.

The five kingdom classes include :

Kingdom Monera

Kingdom protista

Kingdom plantae

Kingdom Fungi

Kingdom Animalia.

Answer:

For each ball, the crater diameter increased as the height of the ball drop increased. My conclusion is that crater diameter increases with increasing mass. Also as the height of the ball increases, so does the crater diameter. Thus crater diameter is proportional to the mass and velocity of the impactor.

Answer:

Alpines, Mosses, Lichens etc

Explanation:

These type of plants survive in very harsh conditions in which the mountain regions are associated with.

The conditions include a higher degree of temperature, little or no amount of soil particles, dryness and a very low degree of nutrients available to them which makes their growth usually stunted when compared to plants in other regions.

Explanation:

!!!! there are a few differences between plant and animal cells BUT!! one major difference is their structure, animals are enclosed by a cell membrane, but plant cells have a cell membrane and a cell wall to give them a more solid form another major difference is that plant cells have chloroplasts for photosynthesis whereas animal cells do not because they do not undergo photosynthesis !!!!

A waxy cuticle that covers the outer surface of the plant and prevents drying out through evaporation. The cuticle also partially protects against radiation damage from UV light.

Stomata (singular: stoma) are present in all land plant lineages except liverworts (similar to -but not the same as! – mosses). Stomata are pores or holes which allow for exchange of gasses (such as oxygen and carbon dioxide) between the plant cells and the environment. Stomata or similar structures are necessary in land plants because the waxy cuticle blocks free-flow of gasses.

Roots (or root-like structures) anchor plants to the soil and—in plants with true roots— serve as conduits for water absorption. All land plants except Bryophytes (mosses, liverworts, and hornworts) have true roots. Bryophytes have root-like structures called rhizoids that anchor them to their substrate but are not involved in water absorption (which is less important for Bryophytes because they can only survive in very moist environments).

Mutualistic association with mycorrhizal fungi, which are tightly associated with plant roots. Mychorrhizal fungi are associated with approximately 80% of all land plant species and provide additional surface area for absorption of both water and nutrients from the soil. The fungi share these resources with the plant roots, and—in exchange— the plant shares photosynthetic sugar products with the fungi.

The alternation of generations life cycle, which includes both a multicellular haploid stage and a multicellular diploid stage. Why is this an adaptation to life on land? It isn’t, in and of itself—in fact, it also occurs in *some* green algae, which are aquatic but share a common ancestor with all land plants. But specific adaptations to the alternation of generations life cycle have occurred in different lineages of plants, and those adaptations DO function as adaptations to life on land. We’ll consider these adaptations later in this reading.

These are from my text book, from last year.

Answer:

It has cuticle, a waxy, airtight seal that covers plants and allows them to retain water.

It has seeds, plant embryos without a protective cover on the scales of a cone which allows them to disperse into new locations.

It has pollen, but it is not produced in flowers, which allows it to reproduce without the need of water.

Answer:tissue

Explanation:

Tissues are groups of cells that have a similar structure and act together to perform a specific function. The word tissue comes from a form of an old French verb meaning “to weave”. ... Groups of tissues make up organs in the body such as the brain and heart.

Answer:

36 individuals xxyyzz

Explanation:

Available data:

We need to know how many individuals from the F2 are going to be xxyyzz

xxyyzz genotype is the result of a double recombinant event.

First, we need to analyze the given information:

→ Distances between genes

The genetic distance result from multiplying the recombination frequency of each region by 100 and expressing it in map units (MU). So, if we have the genetic distance we can divide it by 100 and get the recombination frequency:

Let us say that region I is the distance between X and Y. And region II is the distance between Y and Z.

GD = genetic distance

RF = Recombination frequency

20MU = RF x 100

20MU/100 = RF

0.2 = RF (Region I)

30MU = RF x 100

30MU/100 = RF

0.3 = RF (Region II)      

Now we have the recombination frequency of Region I and Region II.

→ Interference    

Knowing the interference value will let us know the value of the coefficient of coincidence, which will also lead us to the number of individuals xxyyzz.

I = 40%

I = 1 - CC   ⇒ CC = coefficient of coincidence

Clearing this equation gives us the value of CC

CC = 1 - I

CC = 1 - 40% = 1 - 0.4

CC = 0.6

To calculate the coefficient of coincidence, CC, we can also use the next formula:

CC = observed double recombinant frequency/expected double recombinant frequency

Now, we are interested in knowing the value of the observed double recombinant frequency.

Note:  

So, to get the value of the observed double recombinant frequency, first, we need to get the value of the expected double recombinant frequency. And we can do it because we already have the recombination frequencies in both regions.

expected double recombinant frequency = recombination frequency in region I x recombination frequency in region II

- Recombination Frequency - RI = 0.2

- Recombination Frequency  - RII = 0.3

expected double recombinant frequency = 0.2 x 0.3

expected double recombinant frequency = 0.06 = EDRF

Now that we know the value of the CC and the expected DRF, we can get the observed double recombinant frequency.

CC = observed double recombinant frequency/expected double recombinant frequency

- CC = 0.6

- EDRF = 0.06

CC x expected double recombinant frequency = observed double recombinant frequency

0.6 x 0.06 = observed double recombinant frequency

0.036 = observed double recombinant frequency = ODRF

Finally, as this is a frequency, we need to multiply it by the total number of individuals in the F2 to get the number of observed double recombinant individuals.

- ODRF = 0.036

- N = 1000

Double recombinant individuals = 0.036 x 1000 = 36 individuals xxyyzz.
