Since Asha is a healthy woman in her forties, she does not have Niemann-Pick disease type A. For this question, assume that she is a healthy person who is a carrier. If Asha is a carrier of the allele for Niemann-Pick disease type A, what is her genotype? ​

Answers

Answer:

Aa is her genotype

Explanation:

This is because since she is just the carrier and she is healthy, her genotype will be heterozygous with the allele for Nieman pick up disease recessive because it's effect is been masked by the allele that is not Nieman pick up disease because it is dorminant. Therefore , the allele for healthiness is dorminant over allele for Nieman disease.

What will most likely happen if all the chloroplasts are removed from a plant cell?

Answers

In the process of photosynthesis sunlight is absorbed by the chloroplasts to make sugar. Therefore, if chloroplast is taken out of the cell, the green plant will not be able to carry out the process of photosynthesis which means the plant will die.

1. What effect does air pressure have on wind movement?

2. What happens to the density of air as it is heated?

3. It’s a hot, sunny morning in a coastal town in South Florida. Warm air is rising up from the land. Large, puffy clouds are forming overhead. Which way do you think the wind will be moving this afternoon, and what do you think will happen to the temperature?

Answers

Answer:

1. The lower the air pressure the faster the wind the higher the air pressure the slower the winds

2. When the heat of the air increases the density of the air decreases.

3. The air above the ocean will, therefore, be warmer and of low pressure than that over land which will be cooler and of relatively higher pressure. Winds will, therefore, blow seawards because winds blow from high to low-pressure systems.

what is the main way viruses cause diseases in the body?​

Answers

Viruses make us sick by killing cells or disrupting cell function. Our bodies often respond with fever (heat inactivates many viruses), the secretion of a chemical called interferon (which blocks viruses from reproducing), or by marshaling the immune system's antibodies and other cells to target the invader.

This question is asking for the polymer and monomer of nucleotide and protein respectively.

The answer is:

Protein - monomer is AMINO ACID

Nucleotide - polymer is NUCLEIC ACID

Explanation:

There are four major biological molecules found in nature namely: protein, carbohydrates, fats and oil, nucleic acid. These biological molecules are, however, complex and polymeric in nature and like every other polymer, they must contain monomers that make up their structure.

- PROTEINS are made up of monomers called AMINO ACIDS.

- CARBOHYDRATES are made up of monomers called MONOSACCHARIDES.

Which part of the model shows carbon moving from the biosphere to the
atmosphere?

Answers

Answer:

A. Decomposers breaking down the material

Explanation:

Decomposition is the process in which decomposers such as bacteria break down the organic material in the atmosphere.

In the given image, decomposers breaking down the material shows carbon moving from the biosphere to the  atmosphere because decomposers break down the dead organisms and in the process the carbon in the bodies of dead organism get back in to the atmosphere.

Hence, the correct answer is "A. Decomposers breaking down the material".

C. isthesameaspolII D. normally adds about 2000 A nucleotides to the mRNA. E. uses A TP as a substrate.

Answers

Answer:

The correct answer is - option e. uses ATP as a substrate.

Explanation:

Poly-A Polymerase is an enzyme of the family of the DNA polymerase beta (polβ) family which catalyzes the reaction of the addition of AMP from ATP to the DNA polymerase beta (polβ) family.

ATP+RNA-3'OH--------->Pyrophosphate + RNApA-3'OH.

In this reaction, after the mRNA is cleaved, the Poly-A Polymerase template-independently adds about 200 A nucleotides (from ATP) one by one.

Power plants (especially fossil-fuel based coal and gas-fired units) are frequently mentioned sources of environmental problems. List three specific types of outputs to the environment resulting from these fossil plants. Which other parts of the life cycle of producing electricity from fossil plants also contribute to these problems

Answers

Answer:

Effects of Conventional (fossil fuels & gas fired) power plants : Air pollution, Water Pollution, Land Degradation

Explanation:

Fossil power plants, that use fossil fuels for electricity generation, have various ill environmental effects

Air Pollution - Coal Power Plants emit many polluting gases into environment. Like Sulphur Dioxide, Carbon Monoxide etc, Nitrogen Oxides. The last gas is majorly emitted during process of nitrogen combustion.

Water Pollution - Coal washing process before placing it in boiler (for heat generated electricity) , circulates the same unclean water into water bodies & groundwater.

Land Degradation - The after process disposal mechanism implies untreated water & air pollutants released indiscriminately. This adversely effects the land quality & the wildlife.

In a normal respiratory cycle the volume of air that moves into and out of the lungs is about 504 mL. The reserve and residual volumes of air that remain in the lungs occupy about 2030 mL and a single respiratory cycle for an average human takes about 4 seconds. Find a model for the total volume of air V(t) in the lungs as a function of time.

Answers

Answer:

[tex]V(t)=252sin(\frac{\pi}{2}t )+2282[/tex]

Explanation:

The volume of air increases and decreases, hence the volume of air can be represented as a sine function.

A sine function is of the form:

y = Asin(B(x - C)) + D

Where A is the amplitude, B is the frequency, C is the horizontal shift and D is the vertical shift.

Therefore, the total volume of air V(t) in the lungs as a function of time is given by:

V(t) = Asin(B(t - C)) + D

Since the volume of air in and out of the longs is 504 ml, hence the amplitude (A) = 504/2 = 252

There is residual air of 2030 ml minimum in the lungs and a maximum of 2534 ml (2030 ml + 504 ml), hence the vertical shift (D) = (2534 + 2030) / 2 = 2282 ml

The frequency B = 2π / 4 s = π/2

Therefore:

[tex]V(t)=252sin(\frac{\pi}{2}t )+2282[/tex]
