Answer:

Porotic hyperostosis and an iron deficiency anemia

Explanation:

Iron deficiency anemia is a popular type of anemia caused by the deficiency of the mineral iron in the blood. The body needs iron to produce hemoglobin which helps to distribute oxygen in the body. When there is no iron in the blood, the entire body would be deprived of oxygen.

Porotic hyperostosis is a condition whereby the bones in the skull or cranial vault becomes spongy and swells. The cause of the condition could be the hemolytic or megaloblastic anemia that occurs as a result of excessive production of hemoglobin.

1) Describe the process of osmosis

2)What is ostmotic pressure?

3)Describe the importance of a semipermeable membrane in osmosis?

4)Explain the connection between isotonic solutions and osmosis

5)Why is osmosis referred to as an example of facilitate diffusion?


ANSWER THESE CORRECTLY AND YOU WILL GET 55 points!

Answers

1. Osmosis is a process which occurs when there is a difference in solute concentration between two solutions separated by a semipermeable membrane.

2. Osmotic pressure is the minimum pressure which needs to be applied to a solution to prevent the inward flow of its pure solvent across a semipermeable membrane. It is also defined as the measure of the tendency of a solution to take in pure solvent by osmosis.

3. The semipermeable membrane limits the diffusion of solutes in the water.

4. In an isotonic solution, the flow of water in and out of the cell is happening at the same rate. ... Water moves into and out of cells by osmosis.

5. Osmosis is basically diffusion with water. ... The most common example of facilitated diffusion is the movement of water across a cell membrane through transmembrane proteins, which requires no energy. They are simply powered by the concentration differences of the molecules between the two sides of the cell membrane.

A space ship's momentum will continue to carry it forward indefinitely at a constant speed after the engines are turned off.

What do you mean by momentum?

Momentum in a simple way is a quantity of motion. Here quantity is measurable because if an object is moving and has mass, then it has momentum. If an object does not move then it has no momentum.

Momentum, finance, refers to the capacity for a price trend to sustain itself going forward. Strong momentum can continue in an upward or downward trend, which can be confirmed by changes in trading volume and other technical indicators.

Momentum is how we measure mass that is in motion. Any moving object will have momentum. Under the law of physics, the object's momentum equals mass times velocity. Momentum is affected by the parameters' mass as well as velocity.

The allele for purple flowers (capital P) is dominant.

The allele for white flowers (lowercase p) is recessive.

If one allele is capital P, it doesn’t matter if the other allele is another capital P or a lower case p, the capital P will dominate and purple flowers will show up.

The Punnett Square shows:

PP, Pp, Pp, and pp

• 3 of the offspring have at least one dominant and capital P, so purple flowers show up.

• 1 of the offspring has two lowercase and recessive alleles (p), so white flowers show up.

3/4 or 75% of the offspring will have purple flowers.

Hey There! _____________________________________ Answer:

_____________________________________ PEA PLANT:

Pea plant has purple color flowers dominant over white color flowers.

Purple flower dominant allele is P

White Flower recessive allele is p

We would get White flower pea plant only when the recessive allele is in HOMO.ZYGOUS condition

_________________________________________________________

CONDITIONS:

Hom.ozygous Dominant Alleles: PP (Purple Flower)

Heter.ozygous Dominant Alleles: Pp Purple Flower)

Hom.ozygous Recessive Alleles: pp (White Flower)

____________________________________ CROSS:

Whenever we cross Heterozygous Dominant(Pp) purple flower with another Heterozygous dominant (Pp purple flower), we get 75% of the flowers PHENOTIPICALLY(physical appearance) white flowered, and 25 white flowered Because as you can see in the picture,

The P1 is Pp

The P2 is Pp

When we cross them,

It has 4 offsprings,

PP Hom.ozygous Purple flower  

Pp Heterozygous Purple flower

Pp Heterozygous Purple flower

pp Hom.ozygous white flower

Thus the answer is 75% as there are phynotypically 3 purple flowers present

They actually form ATP, which is essentially energy. Byproducts are water and carbon dioxide. I would say all of these answers are true! Remember though, ATP (energy) is the main product while water and carbon dioxide are byproducts.

The evolution of new organs usually builds on preexisting structures that are modified in form and sometimes function. The embryos of fish, amphibians, reptiles, birds, and mammals all have pharyngeal pouches or gill slits. These pouches develop into gills in adult fish and they are used to absorb oxygen from their watery environment. These same pouches become parts of the in_________ humans.
a) eyes and lungs
b) ear and throat
c) eyes and nose
d) lungs and heart

Answers

Answer:

lungs and heart

Explanation:

lungs and heart is the answer because human lungs is use for gas exchange during respiration or while you breathe. When humans breathe, the lungs absorb oxygen from the inhaled sir into the blood and carbondioxide leaves the blood when we breathe out. The heart pumps the blood, and oxygenated blood are carried in the blood when air is inhaled and carbondioxide leaves the blood when you exhale. The blood carries nutrients and oxygenated blood. Therefore, lungs and heart work hand in hand in absorbtion of oxygen from it's environment.

C.

Answers

The correct answer is D. Fluctuations of limiting factors in the ecosystem affected by the new source of energy.

Explanation

As is mentioned in the statement, the energy from a hydroelectric plant is obtained through the movement of water that makes move some blades which produce energy with it. lLater, this is transformed and transported to the cities. However, to obtain these clean natural renewable resources, it is necessary to take into account what environmental factors may be affected with the implementation of a hydroelectric plant, because the operation of hydroelectric can affect natural processes such as fish migration, patterns of reproduction, feeding, among others that take place in a river, having negative consequences for these species which would cause an imbalance in nature. According to the above, the correct answer is D. Fluctuations of limiting factors in the ecosystem affected by the new energy source.

What form does the radiation that is used to treat cancer take?
SOS
alpha particles
photons
beta particles
neutrons

Answers

Answer:

Photon radiation

A high-energy photon beam is by far the most common form of radiation used for cancer treatment. It is the same type of radiation that is used in x-ray machines, and comes from a radioactive source such as cobalt, cesium, or a machine called a linear accelerator (linac, for short).

The speed of radioactive particles is also an important factor in medical use. Beta particles travel very fast. This, combined with their small size, gives them significant penetrating power. In cancer treatment, for example, beams of beta particles can be created outside the patient's body and directed at tumors.

True breeding plant round seeds (DD) were bred with true breeding smooth
seeds(dd) to produce F1 offspring. F1 offspring were then bred with other F1
offspring. What is the genotypic ratio of the resulting F2 offspring? What is the
phenotypic ratio of the resulting F2 offspring?

Answers

Answer:

Genotypic ratio F2 = 1:2:1

Phenotypic ratio F2 = 3:1

Explanation:

In this case, parental genotypes can produce only one type of gamete, i.e., one parent can produce only D gametes, while the other parent can produce only d gametes. Therefore, all F1 generation will be heterozygous (Aa). An F1 hybrid is the first filial generation of offspring obtained from crossing between different parent types. The F1 will produce two gametes (A; a) in a ratio 1:1, thereby the F2 obtained by crossing F1 offspring will have a phenotypic ratio of 3:1 (3 D_; 1 dd) and a genotypic ratio of 1:2:1 (1 AA; 2 Aa; 1 aa).
