why can b blood donate to AB blood?? ​

Answers

Answer 1

People with type AB+ blood are universal recipients because they have no antibodies to A, B or Rh in their blood and can receive red blood cells from a donor of any blood type. Plasma transfusions are matched to avoid A and B antibodies in the transfused plasma that will attack the recipient's red blood cells.
Answer 2

Answer:

Type B contains the B antigen.

This type is relatively rare (second only to AB). It contains the B antigen on its red blood cells, and the A antibody (to attack A antigens) in its plasma

(ANSWER NEEDED NOW PLS!!) your sister claims that
the digestive system works by itself to give your body energy. She states that small branches from the stomach get food to the cells throughout your body. Do you agree with this statement? Why?

Answers

I think Yes. Because the stomach is divided into four sections, each of which has different cells and functions. For example the food that you eat contains nutrients that give your body energy. The nutrients from the food consumed should travel from the small branches in your stomach in order to allow the cells to supply the nutrients to the rest of the body.

My sister is right. The stomach has structures in its branches that see to the breakdown of food materials.

The digestive system is the system in the body that takes care of the breakdown of food materials and absorption of nutrients from food. The stomach houses most of the structures in the digestive system.

When food is broken down in the stomach, It is sent to other parts of the body via the circulatory system in the body. Therefore, my sister is right.

How big of an advantage does a variant of a gene have to give to start becoming more common in a population?

1. Greater than 0%

2. Greater than 5%

3. Double

Answers

Answer:

The correct answer is 1. Greater than 0%. An allele to become common must have a frequency of at least 0.005%

Explanation:

A polymorphic gene has more than two alleles. The more alleles there are in a population, the more polymorphic the gene is.

In a polymorphic gene, the allelic frequency of the most common allele must be minor of 99%, while the less common allele must have an allelic frequency superior to 0.005%. If any allele does not reach this frequency in the population, it is not considered to be common. In fact, it is considered to be a rare allele.

Answer:

Proteins store energy long term, provide lubrication, and insulate the body

Explanation:

Proteins store energy long term, provide lubrication, and insulate the body  - this is false, this describes the role of fats. Proteins in the form of enzymes catalyze chemical reactions  - this is true, enzymes are an important class of proteins in the bodyProteins provide structures in the body, such as hair and muscles  - this is true, for example our hair is made of a protein called keratin Proteins in the cell membrane help transport substances into and out of cells  - this is true, proteins form important pumps and channels in the cell membrane

The fungus Melampsora lini causes a disease known as flax rust. Different strains of M. lini cause varying degrees of the rust disease. Conversely, different strains of flax are resistant or sensitive to the various varieties of rust. The Bombay variety of flax is resistant to M. lini-strain 22 but sensitive to M. lini-strain 24. A strain of flax called 770B is just the opposite; it is resistant to strain 24 but sensitive to strain 22. When 770B was crossed to Bombay, all F1 individuals were resistant to both strain 22 and strain 24. When F1 individuals were self-fertilized, the following data were obtained:

43 resistant to strain 22 but sensitive to strain 24
9 sensitive to strain 22 and strain 24
32 sensitive to strain 22 but resistant to strain 24
110 resistant to strain 22 and strain 24

Required:
Explain the inheritance pattern for flax resistance and sensitivity to M. lini strains.

Answers

Answer:

Explanation:

Using the Mendelian approach to solve this question, we will understand that the mendelian approach has a pattern for inherited traits.

From the data set given, the total number of the population is:

43+9+32+110 = 194

However, their ratio are being calculated as follows:

43/194 = 0.22

9/194 = 0.05

32/194 = 0.16

110/194 = 0.57

After comparison with the Mendelian's approach, we realize that these results seem to be similar to the 9:3:3:1 ratio.

i.e.  

3/16 = 0.18

1/16 = 0.06

3/16 = 0.18

9/16 = 0.56

The inheritance pattern obviously dictates that the flax experiment proceeds in the pattern found in the Mendelian's Approach and the resistance of the two different strains were arbitrated by two traits.

Sometimes after an intense exercise routine, an individual will have sore muscles 1 to 2 days following the exercise; this is called delayed onset muscle soreness. Although not completely understood, it is believed that one cause of this is damage that occurs to the Z disks and contractile filaments in the muscles. When the body attempts to repair this damage, an inflammatory response occurs that causes soreness a couple of days after the exercise has taken place. Which of these situations would likely lead to less delayed onset muscle soreness in an individual?

a. a mutation in the Z-disk protein that caused the attachment of the Z disk to the titin protein to be stronger
b. a mutation that would reduce the amount of lactic acid buildup in muscle tissue
c. a mutation in the Z-disk protein that caused the attachment of the Z disk to the titin protein to be weaker
d. a mutation that weakens the calcium binding ability of troponin

Answers

Answer:

The correct answer is option A. a mutation in the Z-disk protein that caused the attachment of the Z disk to the titin protein to be stronger

Explanation:

As delayed onset muscle soreness is thought to be led by the inflammatory response of the body in order to repair damage to the Z disks and contractile filaments in muscles, due to the intense exercise.

Mutation in the Z-disk protein would strengthen the connection between Z disks and contractile filaments as it is logical that this mutation could withstand more pressure or intense exercise before damage occurs to these tissues.

A biologist is trying to understand the relationship between water and plant growth. She hypothesizes that if she were to give a plant too much water, it would not grow as much. She designs an experiment to test her hypothesis. She plants 2 same-sized plants in the same amount of soil and places them in the same room. She gives Plant A a normal 200 mL of water daily, and gives Plant B a larger 500 mL of water daily. After 1 week, she notices that Plant A grew more than Plant B.

Answers

Answer:

The plant A grew better because a water needs normal water but if we put more water to the plants then it will die

Look at your model and think about the relationship between oxygen and carbon dioxide in the sealed jar. Which of these statements is true?

Plants release only carbon dioxide during photosynthesis.

Plants use oxygen during photosynthesis.

Plants and animals use oxygen during respiration.

Plants and animals release oxygen during respiration.

Answers

Answer:

Plants use oxygen during photosynthsis.

Explanation:

Oxygen and carbon dioxide in the sealed jar relationship between oxygen and carbon dioxide is that  Plants and animals use oxygen in respiration, hence option c is correct.

What is respiration?

Water and carbon dioxide are converted into oxygen and glucose in photosynthesis and plant uses glucose and releases oxygen as a byproduct.

Oxygen and glucose are converted to water and carbon dioxide in cellular respiration. By-products of the process include carbon dioxide, water, and ATP, which are turned into energy.

Carbon is taken out of the atmosphere by photosynthesis and put back in by cellular respiration.

Therefore oxygen and carbon dioxide have a relationship in respiration, hence option c is correct.

What is an ecosystem?

An ecosystem is defined as a system which comprises of all living organisms and  physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.

Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other for requirement of energy.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.
