Bamboo is a type of grass. In the wild, pandas eat bamboo almost excdusively. For this reason, the availability of bamboo is a significant limiting factor on the panda population. Which statement describes how pandas could become extinct in the wild?O A The bamboo population decreases so low that other limiting factors begin to affect the panda population.
OB. The bamboo population decreases so low that the carrying capacity for pandas becomes zero.
O C. The populations of bamboo and pandas follow a cyclical pattern of increasing and decreasing, until one of them becomes extinct
O D. The populations of bamboo and pandas both follw a pattern of exponential growth, and then both become extinct​

(Q007) I am an adult female primate. I live in a territory with my offspring. My territory is separate from those of other females, so I don't see them often. An adult male has a territory that overlaps with mine, but we hardly ever spend time together. What type of social organization do I participate in?

Answers

Answer:

Solitary social organization.

Explanation:

The most common animal that participates in this type of social organization is the orangutan, also some species of lemurs and tarsiers too.

In this organization, the females are in separate territories, and a male goes to these territories. This one has its territory, which also includes its females' space. It is a polygamous system with one male and various females.

They communicate through sounds and by smelling their partners, and they usually are awake during the night but asleep in trees during the day.

Explanation:

A genetic engineer needs to use gene therapy to help a person with cystic fibrosis. Arrange the following steps in the order the engineer would use them.a. Use only the steps you need. Inject the modified CFRT gene into a fertilized egg and implant into a woman who will be the surrogate mother.
b. Combine the cloned CFRT gene with a disarmed respiratory virus.
c. Clone the CFRT gene from someone with cystic fibrosis.
d. Clone the CFRT gene from someone without cystic fibrosis.
e.Modify the CFRT gene by putting on a different promoter
f. Test the patient’s blood cell DNA with PCR to see if they have the CFRT transgene.
g. Have the patient use an inhaler that contains the modified respiratory virus.

Answers

Answer:

d-b-g-f

Explanation:

1. Clone the CFRT gene from someone without cystic fibrosis.

This will make millions of copies of the gene (wild type, not being mutated and thus unable of producing the disease).

2. Combine the cloned CFRT gene with a disarmed respiratory virus.

This step will allow the virus to transport the gene of interest.

4. Have the patient use an inhaler that contains the modified respiratory virus.

This step helps the virus to enter and infect the patient's cells and thus allowing the copies of the transgene to be integrated into the patient's genome.

3. Test the patient's blood cell DNA with PCR to see if they have the CFRT transgene.

This will confirm if the transgene has actually been integrated into patient's genome.

Where does carbon come from in a winogradsky column? 2. why is carbon important? 3. what purpose does calcium sulfate serve in the winogradsky column? 4. why is a hydrogen sulfide gradient generated from bottom to top in a winogradsky column? 5. how is photosynthesis different between cyanobacteria (growing at the top of the column) and green and purple sulfur bacteria (growing near the bottom 1/3 of the column)?

Answers

Answer:

1.The Winogradsky section is a straightforward gadget for refined an enormous decent variety of microorganisms.The gadget is a segment of lake mud and water blended in with a carbon source, for example, paper which contains cellulose, darkened marshmallows or egg-shells which contains calcium carbonate.

2. carbon is important for providing cellulose for winogradsky column.

3.calcium sulphate in the form of gypsum or plaster of paris, craft or garden stores is used. green suphur bacterias and purple sulphur bacterias are formed after 2 to 6 weeks.

4.A hydrogen sulfide slope is created from the base to top in a Winogradsky section since sulfur-decreasing microorganisms like Desulfovibrio (microbes that utilizes maturation side-effects like Ethanol and Organic acids from Clostridium as a carbon source by means of anaerobic breath) produce a lot of H2S as a result of anaerobic breath. The H2S gradually diffuses upwards and is utilized by different life forms. The explanation the angle is higher at the base is on the grounds that anaerobic microscopic organisms like  Desulfovibrio can't endure where O2 is available. The further down in a Winogradsky section the more anaerobic the earth. Along these lines, bigger measures of H2S are created at base of segment in light of the fact that there is a higher grouping of anaerobic microorganisms that produce H2S at the base as side-effect of their anaerobic breath process

5.Rather than utilizing water to photosynthesize, similar to plants and cyanobacteria, purple sulfur microscopic organisms use hydrogen sulfide as their decreasing operator, which is the reason they radiate sulfur as opposed to oxygen.

Explanation:
Carbon comes from blackened marshmallow or egg-shells, newspapers which contain cellulose, and sulphur source, for example, calcium sulphate in winogradsky column.
Carbon is important because it promotes the growth of different microorganisms. For example chlorobium, chromatium, rhodomicrobium, and Beggiatoa. 
Hydrogen sulphide gradient is generated from bottom to the top in a winogradsky column because they dominate the zone with sulphur which reduces bacteria.
Photosynthesis is different between cyanobacteria and green and purple sulphur which is sulphur anaerobic bacteria being the top layer of aerobic bacteria which produces carbon dioxide which feeds back into the column by creating another reaction.

pepsin is found in the stomach. Salivary amylase is found in the mouth. And arginase is found in the liver. What does the graph indicate about the relative acidity of these three locations?

Answers

Pepsin is found in the stomach. Salivary amylase is found in the mouth. Arginase is also found in the liver. The pH of the pepsin in the stomach is acidic. The pH of the pepsin in the stomach is acidic (around 2), the mouth pH is nearly neutral, and the liver pH is basic.

What is the pH of different organs?

Different organs of the body function well at different pH levels because enzymes exhibit their best activity in a specific pH range The enzyme that acts in the stomach can't act in the mouth due to a change in pH. The mouth has a nearly neutral pH, ranging from 6.5 to 7, and in this place, the salivary amylase works best and carries out the initial digestion of the carbohydrates. Pepsin works in stomach having a pH nearly 2.

Hence, the pepsin enzyme in the stomach works best at an acidic pH of about 2. The amylase works best at neutral pH. The liver enzyme arginase works best at a basic pH.

Explain the difference between epistasis end dominance How many loci are involved in each case?

Answers

Answer:

Dominance:

Dominance may be defined as the phenomena in which intra allelic genes are involved in the process. The dominant trait hides the expression of the recessive trait. The same alleles of the gene are involved in this expression. Two loci of the same gene are involved in the dominance.

Epistasis:

Epistasis may be defined as the phenomena in which inter allelic genes are involved in the process. The one gene modifies the expression of the other gene. Different gene are involved in this process. Four loci of two different genes are involved in the process of epistasis.
