Answer 1

Answer:

birds have feathers, reptiles have scales

birds are endothermic, while reptiles are generally ectothermic

Explanation:

The main difference between birds and reptiles  is that birds have feathers on their body while on the other hand, reptiles ahve dry skin and have scales. Reptiles are ectotherms, while birds are endotherms. An ectotherm relies on its external environment to regulate the temperature of its body whereas Endotherms are able to regulate their body temperatures by producing heat within the body.

what is cyclin dependent kinase?​

Answers

Answer:

please mark as brainliest answer as it will also give you 3 points

Explanation:

Cyclin-dependent kinases (CDKs) are the families of protein kinases first discovered for their role in regulating the cell cycle. They are also involved in regulating transcription, mRNA processing, and the differentiation of nerve cells.[1] They are present in all known eukaryotes, and their regulatory function in the cell cycle has been evolutionarily conserved. In fact, yeast cells can proliferate normally when their CDK gene has been replaced with the homologous human gene.[1][2] CDKs are relatively small proteins, with molecular weights ranging from 34 to 40 kDa, and contain little more than the kinase domain.[1] By definition, a CDK binds a regulatory protein called a cyclin. Without cyclin, CDK has little kinase activity; only the cyclin-CDK complex is an active kinase but its activity can be typically further modulated by phosphorylation and other binding proteins, like p27. CDKs phosphorylate their substrates on serines and threonines, so they are serine-threonine kinases.[1] The consensus sequence for the phosphorylation site in the amino acid sequence of a CDK substrate is [S/T*]PX[K/R], where S/T* is the phosphorylated serine or threonine, P is proline, X is any amino acid, K is lysine, and R is arginine.[1]

c. The likelihood Of colonization by skin pathogens is ____________ when normal microbiota are present.
d. The occurrence of opportunistic infections ___________ in immunocompromised patients.

1. Higher
2. Lower

Answers

Answer:

a. lower

b.higher

c.lower

1.Higher

Explanation

Moisture is a great environment for bacteria to grow, the moister the environment is the more the bacteria will thrive, thinking about this lower moisture levels will result in lower microbial diversity.

The small intestine has higher ph than the stomach, this means that the bacteria there thrive in higher ph than the stomach bacteria.

Normal microbia in the skin usually acts as the first barrier against pathogens, while we have normal microbia it will protect us and will be less likely to get skin pathogens.

Immunocompromised patients are people that have received treatment to reduce their immunological system capacity, this means that even though this is done to battle a disease, another opportunistic infection can appear and take advantage of the fact that the defenses are low.

A. Fluorescence-activated cell sorting of unstained cells.B. Serial dilution followed by an optical density measurement.C. Counting cells directly using a hemocytometer.D. Serial dilution followed by a colony forming units calculation.

Answers

Answer:

D. Serial dilution followed by a colony forming units calculation.

Explanation:

The best way to count bacterial cells such as Salmonella accurately is through serial dilution and calculation of colony forming units.

Serial dilution is made using a petri dish containing appropriate culture medium for Salmonella growth. In this petri dish, with the help of an inoculation loop, the suspension containing the Salmonella will be scratched in the middle of the petri dish. Then, the inoculation loop will be passed over the salmonella streaks and will be dragged to the other side of the plate, where the loop will be scratched halfway through this space. The inoculation loop should again pass over the new salmonella streaks and be dragged through the rest of the petri dish. Then one must wait for the bacterial colonies to grow inside the plate.

Once these colonies are grown, those that appear in isolation will be counted through a specific calculation for the count of salmonella colonies.

In a Nitrogen metabolism study, the following data were obtained over the test period:

Nitrogen consumed 175 grams
Total Fecal N 35 grams
Metabolic Fecal N 10 grams
Total Urinary N 80 grams
Endogenous Urinary N 10 grams

Calculate:
a. Apparent Nitrogen digestibility (%)
b. True Nitrogen digestibility (%)
c. Nitrogen Balance (g)
d. Apparent Nitrogen Retention (%)

Answers

Answer:

a. 80%

b. 86%

c. 60 g

d. 34.29%

Explanation:

From the given information:

The apparent nitrogen digestibility (AD) is the ratio of the difference between the consumed nitrogen and fecal nitrogen to the consumed nitrogen.

Mathematically:

[tex]AD = \dfrac{consumed \ nitrogen - fecal \ nitrogen }{consumed \ nitrogen }[/tex]

[tex]AD = \dfrac{175 -35 }{175}[/tex]

AD = 0.8

To percentage, the apparent Nitrogen digestibility = 80%

b. True Nitrogen digestibility is calculated by the formula:

[tex]=\dfrac{consumed \ nitrogen - (fecal \ nitrogen -metabolic \ fecal)}{consumed \ nitrogen}[/tex]

[tex]= \dfrac{175 -(35-10)}{175}[/tex]

[tex]= \dfrac{175 -25}{175}[/tex]

= 0.86

= 86%

c. Nitrogen Balance = consumed Nitrogen - Fecal nitrogen - total uninary

Nitrogen Balance = (175 - 35 - 80) grams

Nitrogen Balance = 60 g

d. Apparent Nitrogen Retention (ANR) is computed as follows:

[tex]ANR = \dfrac{(consumed \ nitrogen-fecal\ nitrogen - total \ uninary )}{nitrogen \consumed }\times 100\%[/tex]

[tex]ANR = \dfrac{(175-35- 80 )}{175 }\times 100\%[/tex]

[tex]ANR = \dfrac{(60 )}{175 }\times 100\%[/tex]

ANR = 34.29%
