Answer:

Fossils provide solid evidence that organisms from the past are not the same as those found today; fossils show a progression of evolution. Fossils, along with the comparative anatomy of present-day organisms, constitute the morphological, or anatomical, record. By comparing the anatomies of both modern and extinct species, paleontologists can infer the lineages of those species. This approach is most successful for organisms that had hard body parts, such as shells, bones or teeth. The resulting fossil record tells the story of the past and shows the evolution of form over millions of years.

The answer is below

Explanation:

The weight of trees is calculated using the equation:

[tex]W=b_o+b_1(D^2H)[/tex]

Where W is the weight in tons, [tex]b_o \ and\ b_1[/tex] are constants , D is the diameter of the tree in inches and H s]is the height of the tree in feet.

The circumference = 14 inches. But circumference = 2πr, where r is the radius and π = 22/7. Therefore:

14 = 2(22/7)× r

14 = (44/7)×r

r= 14 × 7 / 44 = 2.23 inches

Diameter = 2r = 4.45 inches

[tex]W=b_o+b_1(4.45^2*120)\\W = b_o+2381b_1\\Let\ us\ assume\ b_o = -34.671,b_1=1.859.\\Therefore\\W = -34.671+2381(1.859)\\W=4392 \ tons[/tex]

Vertical farming is the practice of growing local crops like fruits and vegetables with minimal resources by using high technological methods in a controlled environment.

It has been said to be the future of agriculture in the UAE since they huge amount of goods and have to find ways to be self sustaining by boosting local production. Apart from being self sustaining, they also aim to provide safe and nutritious food.

The vertical garden is an agriculture concept for growing plants inside buildings or multi-story skyscrapers, often called farmscrapers, a term derived from the English skyscraper. In these buildings, which would function as large greenhouses, agriculture involves the use of technologies such as hydroponics to aid in plant growth. Some projects include the practice of livestock (especially poultry) on the lower floors.

Therefore, Vertical farming is the practice of growing local crops like fruits and vegetables with minimal resources by using high technological methods in a controlled environment.

B. 1/2 and 1/4

Explanation:

Hemophilia is a disease inherited in humans. It is only carried on the X chromosome, hence, it is said to be X-linked. In this question;

X - unaffected X chromosome

x = X chromosome affected by hemophilia,

Y = Y chromosome

Hence, in a cross between a Xx female (carrier) and a XY male (unaffected), the following chromosomes will be present in the gametes produced by each parent:

Xx- X and x gametes

XY- X and Y gametes

Using these gametes in a punnet square (see attached image), offsprings with genotypes: XX, Xx, XY and xY are produced.

XX (1) - unaffected normal female

Xx (1) - unaffected carrier female

XY (1) - unaffected normal male

xY (1) - affected male

Based on the questions;

- 2 out of the possible 4 children have the affected chromosomes i.e. both xY son and Xx daughter have the x chromosome. Hence, the fraction is 1/2

- 1 out of the 4 possible children is affected by hemophilia, which is the xY son. Hence, the fraction is 1/4.

Answer:

below

Explanation:

there are so many different kinds of living things that its so difficult to classify them as there would be too many classifications that it would become absurd to have only a few organsims in a single group. the role of classification is to organize as well as simplify so it proves to be a challenge when the subgroups branching from eukoryotes vs prokaryotes become too small and therefore it becomes a giant mess.  even the current classification system (taxonomy) is flawed.

The problems/challenges associated with classifying living things is : The challenge of having a very small number of living thing classified into a subgroup and having an enormous amount of subgroups.

Although the main reason of classification of organism is to organize/categorize every living thing into a suitable group as well as simplify the subgroups( this leads to having a lot of subgroups ). there is also a challenge whereby the subgroups become so small when trying to categorize every organisms following all the rules of taxonomy. while

Taxonomy is the science of classifying living things into different groups and subgroups following certain similar characteristics exhibited by the organism.

An example is : The subgroups of eukaryotes vs prokaryotes becoming  too small. because the rules of Taxonomy been followed.

hence the challenges are: very small number of living thing classified into a subgroup and having an enormous amount of subgroups.

Explanation:

If the gametes will be diploid then on fusing the resulting embryo would have double the amount of DNA it should have. The correct option is B.

A gamete is an animal or plant procreative cell. Female gametes are known as ova or egg cells in animals, while male gametes are known as sperm.

Ova and sperm are haploid cells, with only one copy of each chromosome in each cell. A sperm and an ovum combine during fertilization to form a new diploid organism.

As in case of diploid gamete, the embryo will have double amount of DNA than normal and will create defect.

Answer:

Bacteria, Archaea, and Eukarya represent the three domains of life by which all living organisms are classified. This type of classification was coined by Carl Woese et al. (1990). Archaea and Bacteria represent different domains because Archaea is considered to have the evolutionary oldest phenotypic features, while Bacteria species have diacyl glycerol diester lipids in their membranes. On the other hand, the Eucarya domain is composed of organisms that possess a nuclear envelope (membrane).  

Cladistics is a biological method used to classify organisms into groups named 'clades'. In this type of classification, organisms are categorized according to the most recent common ancestor. In this regard, it is possible to find the most recent common ancestor by using nucleotide differences between taxa.

Viruses can be classified in a similar manner to the cellular organisms above described. Viruses are categorized according to morphological features, type of nucleic acid (DNA or RNA) by which they are composed, mode of replication, host organisms, etc. Viruses may also be classified according to the type of disease that they cause. There are viruses that cause chickenpox, rabies, influenza, old sores, Ebola, AIDS (HIV), Severe acute respiratory syndromes (SARS), etc.

Describe classification as a work in progress

Since it reflects the most current understanding of how living things are related, new discoveries can change the way living things are classified also something is always changing.

Discuss the characteristics of the three domains: Bacteria, Archaea, and Eukarya

Bacteria includes common bacteria, Eukarya includes the four kingdoms: plants, animals, fungi, and protists. Archaea includes some of the oldest organisms on the planet.

Describe classification by cladistics

Cladistics depict hypothesis about how organisms are related based n their ancestors and descendants.

surface waves decay more slowly with distance than body waves, which travel in three dimensions. The particle motion of surface waves is larger than that of body waves, so surface waves tend to cause more damage. Surface waves. Their side-to-side motion (like a snake wriggling) causes the ground to twist from side to side, that's why Love waves cause the most damage to structures. Rayleigh waves create a rolling, up, and down motion with an elliptical and retrograde particle motion confined to the vertical plane in the direction of propagation.

Explanation:

There are different methods of sterilization, such as ultraviolet radiation, autoclave mechanisms, etc.

The sterilization mechanisms eliminate the microorganisms completely, thus generating sterile surfaces.

These mechanisms are used with surgical instruments, the operating room environment.

The autoclave method is the most widely used today due to its economical price, its ease of use and its practicality.

Sterilization methods must be strictly controlled with pilot or test microbiological cultures to be able to corroborate that these mechanisms function correctly, since otherwise they could trigger strong pathologies due to cross contamination.

Explanation:

A cladogram is a diagram capable of showing the relationships among different species and/or group of organisms. In a cladogram, the root indicates the common ancestor, while internal nodes represent the common ancestors of each group. In consequence, this diagram can be used to establish evolutionary relationships in which the start branch points represent common ancestors shared by the organisms found in the 'branches'. Nonetheless, the length of the branches in the cladogram does not represent evolutionary distances among groups. In recent years, cladograms based on DNA sequencing data have been combined with morphological data to establish evolutionary relationships among species.
