Answer:

- La genética microbiana ha sido fundamental para la comprensión de diferentes mecanismo genéticos y evolutivos  

- Los microrganismos son ampliamente utilizados en medicina y procesos biotecnológicos  

- La microbiología ha permitido descartar la teoría de la generación espontanea (anteriormente aceptada en biologia) como así también formular nuevas teorías (hoy en día ampliamente aceptadas por la comunidad científica)

Explanation:

La genética microbiana juega un papel fundamental en biología, ya que los organismos microscópicos (por ejemplo, bacterias) poseen características únicas para el estudio de mecanismos genético/moleculares tales como, por ejemplo, 1-un corto tiempo generacional y 2-la capacidad de manipulación de un número de organismos muy alto (N muestral) en un laboratorio. En consecuencia, los microrganismos permiten estudiar mecanismos genéticos y evolutivos con mayor grado de precisión y versatilidad al ser comparados con organismos pluricelulares. La microbiología ha permitido el desarrollo de técnicas esenciales en el campo de la biología molecular: la técnica de edición genómica CRISPR-Cas9 se basa en el sistema adaptativo que poseen ciertas bacterias para hacer frente a infecciones virales. La biotecnología microbiana ha permitido también desarrollar diferentes tipos de alimentos y procesos biotecnológicos (por ejemplo, la cerveza y ciertos productos lácteos requiere la utilización de microrganismos para llevar a cabo el proceso de fermentación). Por otra parte, mediante técnicas de recombinación genética podemos explotar las características de los microrganismos para producir a gran escala ciertos productos biotecnológicos y medicinales (por ejemplo, producir insulina para uso humano). La microbiología emergió en la segunda mitad del siglo XIX y desde entonces ha posibilitado el desarrollo de importantes avances para el tratamiento y cura de enfermedades infecciosas, como así también descartar teorías tales como la generación espontánea y generar nuevos conocimientos en el campo de la biología y la genética (por ejemplo, el descubrimiento que el ADN se replica de manera semiconservativa fue realizado utilizando cepas de E. coli).

Answer:

Immune responses to antigens may be categorised as primary or secondary responses. The primary immune response of the body to antigen occurs on the first occasion it is encountered. Depending on the nature of the antigen and the site of entry this response can take up to 14 days to resolve and leads to the generation of memory cells with a high specificity for the inducing antigen. The humoral response, mediated by B cells with the help of T cells, produces high-affinity and antigen-specific antibodies. This is in contrast with the CD8 T-cell response which leads to the generation of large numbers of antigen-specific cells that are capable of directly killing infected cells. Antigen-specific CD4 T cells, which provide help to B cells in the form of cytokines and other stimulatory factors, can also be expanded upon antigenic stimulation.

The secondary response of both B- and T cells is observed following subsequent encounter with the same antigen and is more rapid leading to the activation of previously generated memory cells. This has some quantitative and qualitative differences from the primary response.

Answer:

Các vi khuẩn Psychrotolerant rất quan trọng đối với các ứng dụng công nghệ sinh học và chu trình cacbon. Tuy nhiên, các cơ chế cho phép chúng tồn tại và hoạt động trong môi trường đông lạnh vẫn chưa rõ ràng. Để làm sáng tỏ sự thích nghi của màng tế bào vi sinh vật với sự đóng băng, chúng tôi ủ đất với glucose được đánh dấu 13C theo vị trí cụ thể ở + 5 (đối chứng), - 5 và - 20 ° C và định lượng 13C trong CO2 và axit béo phospholipid. Quá trình oxy hóa cao của glucose C-1 ở + 5 ° C cho thấy sự biến đổi thông qua con đường pentose phosphate. Tuy nhiên, ở nhiệt độ subzero, sự oxy hóa ưu tiên của vị trí C-4 gợi ý chuyển sang quá trình đường phân. Sự gia tăng gấp ba lần axit béo photpholipid Gram âm trong đất ủ ở - 5 ° C đi kèm với sự gia tăng gấp hai lần sự kết hợp ở 13C. Sự gia tăng không đều này của các axit béo phospholipid và kết hợp 13C có thể được giải thích là do sự khử bão hòa đồng thời của các chuỗi axit béo hiện có và sự tổng hợp de novo của các axit béo không bão hòa đơn, cho thấy sự phát triển của vi sinh vật. Ngược lại, vi khuẩn Gram dương kết hợp các axit béo phospholipid ở nhiệt độ - 20 ° C cao hơn 2 lần so với ở - 5 và + 5 ° C mà không làm tăng đáng kể hàm lượng axit béo của chúng. Điều này phản ánh việc sửa chữa chuyên sâu các màng bị hư hỏng ở - 20 ° C mà không có sự phát triển của vi sinh vật. Tỷ lệ nấm / vi khuẩn thấp hơn 1,5 lần ở nhiệt độ subzero so với + 5 ° C, phản ánh sự thay đổi cấu trúc cộng đồng vi sinh vật theo hướng vi khuẩn. Theo đó, vi sinh vật đất thích nghi với sự đóng băng bằng cách (1) chuyển con đường trao đổi chất của chúng từ con đường pentose phosphate sang đường phân, (2) điều chỉnh axit béo phospholipid bằng cách khử bão hòa và, (3) chuyển cấu trúc cộng đồng vi sinh vật sang vi khuẩn Gram âm bằng cách khử nấm dân số.

Answer:

Yeast

Explanation:

The correct answer would be yeast.

Yeast belongs to the fungi kingdom. Organisms in the fungi kingdom are generally eukaryotic in that their cells contain a nucleus and membrane-bound organelles such as mitochondrion. Fungal cells lack chlorophyll and are therefore nonphotosynthetic. They are also nonmotile

While fungi exhibit different body forms in terms of body complexity, the only unicellular form is yeast. The organism possesses all the attributes of fungi highlighted above, has a cell wall made largely of chitin, and reproduces through budding.

Answer: Yeast.

Explanation:

Yeasts are eukaryotic organisms, more precisely microscopic fungi that do not form filamentous networks (hyphae), classified as ascomycetes or basidiomycetes and are predominantly unicellular in their life cycle. The cell wall of yeasts is composed of complex "B"-glucan polysaccharides, mannoproteins and chitin. Also, yeast are non-motile organisms when they grownon a solid media.

They usually reproduce asexually by budding or bipartition and by having sexual stages that are not attached to a sporocarp (fruiting body). During asexual reproduction, a new bud emerges from the mother yeast when suitable conditions are met, after which the bud separates from the mother upon reaching adult size. In the case that they reproduce sexually, this occurs by means of ascospores or basidiospores. In conditions of nutrient scarcity, yeasts that are able to reproduce sexually will form ascospores.

Yeasts are important because of their ability to carry out the decomposition by fermentation (predominantly alcoholic) of various organic compounds, mainly sugars or carbohydrates, producing different substances. Therefore, they do not photosynthesize to obtain energy, since they do not possess chlorophyll (pigment responsible for capturing solar energy for photosynthesis).

Answer:

Organs are grouped into organ systems, in which they work together to carry out a particular function for the organism. For example, the heart and the blood vessels make up the cardiovascular system.

Explanation:

Answer:

Due to exchange of gases i.e. normal and abnormal.

Explanation:

The main difference between incomplete and complete ventilation is the occurrence of normal and abnormal exchange of gases. The mechanism in which the exchange of gas happens completely without any difficulty is called complete ventilation. It is the process in which the required amount of oxygen is inhaled or inspired and appropriate amount of carbon dioxide is exhaled out of the body while on the other hand, incomplete ventilation is a mechanism in which exchange of gases is not normal.

por que tienes genes que provienen de ellos y de tus antepasados

Explanation:que es un gen?

Answer:

a) k_m = 4.08 uM

  V_{max} = 20.07 uM/min

b) k_m = 8.16 uM

Explanation:

Given that:

For Enzyme A:

the substrate concentration [S] = 40 uM

the initial velocity rate v = 10 uM/min

when it was 4mM, v = 20 uM/min

i.e.

at 4mM = 4000 uM;

Using Michealis -menten equation;

when v = 10

[tex]V = \dfrac{V_{max}[S]}{k_m+[S]}[/tex]

∴

[tex]10 = \dfrac{V_{max}\times 40}{k_m + 40}[/tex]

[tex]10 (k_m + 40) = V_{max}40[/tex]

[tex]40V_{max} -10k_m = 400 --- (1)[/tex]

when v= 20

[tex]20= \dfrac{V_{max}\times 4000}{k_m + 4000}[/tex]

[tex]20 (k_m + 4000) = V_{max}4000[/tex]

[tex]4000V_{max} -20k_m = 8000 --- (2)[/tex]

equating equation (1) and (2):

[tex]40V_{max} -10k_m = 400 --- (1)[/tex]

[tex]4000V_{max} -20k_m = 8000 --- (2)[/tex]

let multiply equation (1) by 100 and equation (2) by 1

4000V_{max} - 1000K_m = 4000

4000V_{max} - 20 k_m = 8000    

  0        -980k_m = 4000

k_m = 4000/-980

k_m = 4.08 uM

replacing the value of k_m into equation (1)

40{V_max } - 10(4.08) = 400

40{V_max } - 40.8 = 400

40{V_max } = 400 +  40.8

40{V_max } = 440.8

V_{max} = 440.8/40

V_{max} = 11.02 uM/min

b)

Since V_{max} of A ie equivalent to that of B; then:

V_{max} of B = 11.02 uM/min

Here;

[S] = 80  uM

V = 10 uM/min

∴

[tex]10 = \dfrac{11.02 \times 80}{k_m + 80 }[/tex]

10(k_m +80) = 881.6

10k_m = 881.6  - 800

10k_m = 81.6

k_m = 81.6/10

k_m = 8.16 uM

By presenting the source, it would make the post more trustworthy and relevant.

Answer:

Explanation:

The evolutionary tree is composed of,

Two or more lineages are more related to each other if they share a recent common ancestor -In this example, X and Y are more related to each other-. This means that they all diverge from the same node.

Two or more lineages are less related to each other if they lack a recent common ancestor. This is, the node from which these lineages diverge is placed far away in the tree.
