Sergeu [11.5K]

The two bacteria are considered to be anaerobic endospore-formers that deliver neurotoxins. Disease comes about when the endospores are brought profound into the tissues. The two neurotoxins meddle with engine control. Botulism poison, delivered by C. botulinum, ties the cytoplasmic films of engine neurons at the neurotransmitter and keeps the arrival of acetylcholine neurotransmitter and, subsequently, forestalls motioning to muscle cells. At the point when muscle cells don't get signals from engine neurons, they stay loose, bringing about a flabby loss of motion. The absence of engine control delivers a not insignificant rundown of side effects, the most genuine of which is a respiratory disappointment, on the grounds that respiratory muscles can be influenced by botulism poison.

In the above diagram of a plant cell, what is the function of structure 3?

kramer

Explanation:

B. serves as the control center of the cell and contains the cell's genetic information

All the genetic information within the eukaryotic cell is stored within the nucleus as helical DNA. This DNA is tightly wounucleuscarbohynd around histones as chromosomes. Chromosomes within the nucleus is unwound, unzipped and read by enzymes in a complex series of steps known as transcription. The message on DNA, called genes is copied by RNA polymerase, to form mRNA complementary sequence to that of the DNA strand. These are then translated into proteins in ribosomes.

Further Explanation:

A cell's structural components (i.e. their makeup) determine their function (what they do) . For instance, photosynthesizing cells in algae and plants have structures called chloroplasts. These contain chlorophyll, a specialized compound which facilitates the conversion of light energy to energy stored in carbohydrates. In specific cell types, collected proteins may function as a unit called an organelle. Some organelles are bound by membranes like those that make up the external structure of the cell, with varying compositions of phospholipids and proteins. These are advantageous, as they:

may increase metabolic reaction efficiency; they allow cells to concentrates smaller fractions of enzymes and solutes
separate proteins and molecules that me harm the cell by parceling them into membrane-bound organelles for example, proteaseas bound within lysosomes can break down many structural proteins

A respiratory rate of less than ________ and greater than ________ in cases of trauma are criteria for immediate transportation

vovikov84 [41]

The question is incomplete as it does not have the options which are:

A. 8; 32

B. 10; 29

C. 12; 20

D. 5; 45

Answer:

The correct answer will be option-B

Explanation:

Trauma is the experience caused by the life-threatening events or events which help develop the psychological distress conditions.

The trauma can cause changes in the physiologic and psychological responses in humans. The CDC guidelines have stated criterion for immediate transportation of the person to the trauma centre in which one of the criteria is that if a person has the respiratory rate of less than 10 and greater than 29 will be transported to the trauma centre immediately.

Thus, Option-B is the correct answer.

A population of 100 tigers has 30 with horizontal stripes. Using pedigrees, you ascertain that horizontal striping is caused by

bixtya [17]

Assuming that this population is in Hardy-Weinberg equilibrium, we can sayt that the probability that, given enough time, all tigers in the population will have horizontal stripes is 30% = 0.3.

--------------------------

Available data:

Population size, N = 100 tigers
Number of Tigers with horizontal stripes = 30
Horizontal stripes is caused by an autosomal recessive mutation.

We need to know the probability that all tigers in the population will have horizontal stripes, which is the recessive phenotype.

We assume that the population is in Hardy-Weinberg equilibrium, so there should be no evolution.

Since the population is in H-W equilibrium, the allelic, genotypic and phenotypic frequencies will remain the same generation after generation.

Now, we will calculate the allelic and genotypic frequencies of horizontal striped individuals in the population.

There are 100 individuals, and only 30 have horizontal stripes.

So, the phenotypic frequency, F(HS) is 30/100 = 0.3 = 30%

Since this is a recessive phenotype, this value equals the genotypic frequency, F(hh) = 30%

Finally, we can get the allelic frequency by taking the square root of this value.

F(hh) = q² = 0.3

f(h) = q = √0.3 = 0.55 = 55%

According to these calcs, the probability for the fixation of the recessive allele is 55%, and the probability that all individuals express the recessive horizontal stripes phenotype is 30%.
