The diagram below shows a helium atom. The particles labeled - 1

Answers

Answer 1
Answer:

Particular A shown in the image is called protons, as option B shows.

What are Atoms?

  • It is the basic unit of matter.
  • It is a particle composed of electrons, protons, neutrons, nucleus and electrosphere.

An atom of any element is made up of a nucleus and an electron shell. In the electrosphere, there are small particles with a negative charge. These particles are called electrons.

In contrast, the nucleus has two types of particles, protons that have a positive charge and neutrons that have no charge.

Therefore, when we observe the image shown in the image above, we can see that there are particles with a positive sign, inside the nucleus of the atom. These particles are protons.

In pea plants the trait for tall stems is dominant over the trait for short stems. if two heterozygous tall plants are crossed , what percentage of the offspring would be expected to have thensame phentotype as the parents

Answers

The study of genes and inheritance is called genetics. There are two types of alleles and these are recessive and dominant.

The correct answer is 75%.

What are genes?

  • A gene is a basic unit of heredity and a sequence of nucleotides in DNA that encodes the synthesis of a gene product, either RNA or protein. During gene expression, the DNA is first copied into RNA.
  • The RNA can be directly functional or be the intermediate template for a protein that performs a function

Tall stems are dominant over short stems. Let T represent tall and t represent short. The parents are Heterozygous tall plants, which means that their genotype would be Tt and their phenotype would be tall. In a Punnett square it would look like this:

     T    t

T   TT   Tt

t   Tt    tt

Notice that we have 3 possible genotype combinations. When the dominant allele T is present that means that the phenotype that will be expressed is the dominant trait. In this case, we have the following genotype and phenotype:

TT     Tall        1/4

Tt       Tall         2/4

tt        Short      1/4

The question is asking the chance the offspring phenotype is the same as the parent specifically so we can see that 3/4 are tall.

Hence, the correct is 3/4 = 75%.

Scientists who rely on creativity also tend to be persistent when they pursue a research goal. How might persistence be an advantage for a creative scientist?

Answers

Persistence is important to all individuals in any walks of life. Scientists are not the exception for having this trait. Creativity can be taught but persistence is an attitude. Doing something continuously, efficiently and timely and not be mindful to critics is a great trait for scientists because in the world of discovering things, people always racing for the first discovery or invention. No one was ever credited for being the second, however, people were credited for correcting things thought to be generalized facts in the ancient times so persistence amidst failures has been key for the success of scientists.

X-rays are fast and and simple method of imaging recommended by most of the doctors nowadays, it is painless and doesn't require much preparation and also doesn't require recovery time after having x-rays. The only time that x-rays become dangerous to a persons health is when they are exposed too much of radiation however, this risk is very low.
