Answers

Answer:

kills all microbes that cause disease or spoilage.

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.

what are the problems and the challenges in classifying living things​

Answers

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.

Describe how fossils provide evidence of evolution

Answers

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.

(1 point)
A. 1/4 and 1/2
B. 1/2 and 1/4
C. 1/2 and 1/3
D. 1/4 and 1/4

I've been stuck on this question for a while, may someone please assist?

Answers

Answer:

B. 1/2 and 1/4

Explanation:

Hemophilia is a rare disease that has to do with the inability for blood to clot. It is inherited on the X chromosome, hence, it is said to be X-linked. It is usually passed from mother to son. According to this question;

X - unaffected X chromosome

x = X chromosome affected by hemophilia

Y = Y chromosome

Therefore, 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 will be possibly produced.

XX (1) - unaffected female

Xx (1) - unaffected but carrier female

XY (1) - unaffected male

xY (1) - affected male (have hemophilia)

Based on the questions;

- 2 out of the possible 4 children will have the affected chromosomes i.e. both xY son and Xx daughter have the affected (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.

The correct order of organization in animals is Cell, tissue, organ, organ system, organism—that is what is written in the option D. The cell is the first to form, followed by tissue, and finally organs and organ systems.

What is the organization of an animal?

At the early stage, unicellular individuals were seen, and later, due to development, multicellular individuals were developed. The unicellular organism has only cells, then those cells unite to make a tissue, and in a tissue all the cells have the same function. An example is epithelial tissue, which is made up of many epithelial cells.

Tissues combine to form an organ, and organs combine to form an organ system. An example is an organ such as the liver that is made up of many tissues, but all tissues perform certain functions that are required for the liver, and in the same way, the organ system and the organism are developed.

Hence, the correct order of organization in animals is cell, tissue, organ, organ system, organism—that is what is written in the option D.

briefly outline how cell theory has developed over the past 400 years​

Answers

Explanation:

The cell theory, or cell doctrine, states that all organisms are composed of similar units of organization, called cells. The concept was formally articulated in 1839 by Schleiden & Schwann and has remained as the foundation of modern biology. The idea predates other great paradigms of biology including Darwin’s theory of evolution (1859), Mendel’s laws of inheritance (1865), and the establishment of comparative biochemistry (1940).

First Cells Seen in Cork

While the invention of the telescope made the Cosmos accessible to human observation, the microsope opened up smaller worlds, showing what living forms were composed of. The cell was first discovered and named by Robert Hooke in 1665. He remarked that it looked strangely similar to cellula or small rooms which monks inhabited, thus deriving the name. However what Hooke actually saw was the dead cell walls of plant cells (cork) as it appeared under the microscope. Hooke’s description of these cells was published in Micrographia. The cell walls observed by Hooke gave no indication of the nucleus and other organelles found in most living cells. The first man to witness a live cell under a microscope was Anton van Leeuwenhoek, who in 1674 described the algae Spirogyra. Van Leeuwenhoek probably also saw bacteria

The cell theory, states that all organisms are composed of similar units of organization, called cells.

What is cell theory?

The concept of cell theory was in 1839 by Schleiden & Schwann which leads the foundation of modern biology. Cell theory states that every cell is generated from another preexisting cell.

This idea makes the great revolution in biology including Darwin’s theory of evolution (1859), Mendel’s laws of inheritance (1865), and the establishment of comparative biochemistry (1940).

Schleiden & Schwann propose every organism is composed of the cell, which is the basic unit of life and each cell comes from the preexisting cell, and each cell produces a progeny which is similar to its parent cell.

Therefore, cell theory states the existence of the cell in the organism.
