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.

What is the material that allows plants to capture energy from the sun? How many different types of this material are there? (site 1)

Answers

Answer: The molecules of chlorophyll contained in the chloroplasts absorb energy in the form of light from the sun. This is the process called Photosynthesis, by which plants convert energy from the sun. It is the process that allows plants to create organic molecules that they use as fuel.

Explanation:

During the process of photosynthesis, plants capture light energy and use it to convert water, carbon dioxide, and minerals into oxygen (released into the air) and glucose (stored in the plant and used as food). The photosynthesis process occurs in all plants and algae, as well as in some bacteria species.

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

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.

Sex Linked Inheritance

Why are women often carriers of X-linked traits but rarely affected by them?

Answers

Answer:

See the answer below

Explanation:

Women are often carriers of X-linked traits but are rarely affected by the trait because they have two X chromosomes and the two have to carry the X-linked allele in order for them to be phenotypically affected, especially if the trait is a recessive one.

Unlike men that are XY and only require one X-linked allele in order to be affected for X-linked recessive traits, women need two alleles - one on each chromosome - in order to be affected. One of the X chromosomes of a woman usually comes from the woman's father and the other one from her mother. In order to be affected, a woman must inherit an affected chromosome from her father and her mother respectively, thereby reducing the probability of having the trait.

The X chromosome of a man usually comes from his mother. Hence, a man only needs to inherit an affected chromosome from his carrier mother to be affected for the trait, thereby increasing the probability of having the trait when compared to a woman.

This is not the case for X-linked dominant traits where both men and women have an equal chance of being affected.

Women carry two XX chromosomes in their cells. They carry the X chromosome but rarely gets affected by the trait because to be phenotypically affected they should carry X linked disease trait on both the X chromosomes.

Especially in the case when the trait is recessive then they should have two XX chromosomes which are linked to traits.

In the male, they have one X and one Y chromosome so they acquire an X chromosome and gets affected by it.

In male presence of one X chromosome from the carrier mother is enough to pass the trait. While in females to have X linked recessive trait they should have two alleles.

The woman does not get affected as one chromosome comes from the father and the other from the mother so to be affected the woman must acquire genes with traits from both parents.

Therefore, women are often carriers but are rarely affected by them.

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).

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.
