<h2>Question:</h2>

Sofia, a scientist, wants to change the DNA of a sexually reproducing organism and have the

new DNA present in every cell of the organism. In order to do this after fertilization, she would

change the DNA in which of the following?

A. Zygote

B. Placenta

C. Testes of the father

D. Overuse of the mother

<h2>Answer :</h2>

C. <em>Testes of the father</em>

<em>ありがとうございました</em><em>!</em>

<h2>Explanation:</h2>

<em>Men</em> determine the sex of a baby depending on whether their sperm is carrying an X or Y chromosome. An X chromosome combines with the mother's X chromosome to make a baby girl (XX) and a Y chromosome will combine with the mother's to make a boy (XY)

Answer:

1. Both

2. Lamarck
3. Darwin
4. Darwin
5. Lamarck
6. Both
7. Both
8. Darwin
9. Lamarck
10. Both

Explanation:

in 1, we need time therefore both. In 2, Lamarck because in Darwinian evolution, species change not organisms. In 3, Darwin because of natural selection, mutation, and probably a little bit of heredity. 4 is Darwin because in Lamarckian evolution. 5 is Lamarck because based on natural selection, organisms should go extinct. 6 is both because they both rely on the environment. 7 is both because of heredity. 8 is Darwin because in Lamarckian evolution, traits acquired throughout ones lifetime can be passed down to offspring. 9 is Lamarck because in Darwinian evolution, organisms do not decide their traits. 10 is both because both idea ssupport the idea that organisms, be it in Lamarckian or Darwinian evolution, are still and will carry out on changing.

stealth61 [152]

In a DNA molecule, the complementary strand is the one composed of bases that pair -complement- the bases of the original strand. The complementary strand is TACCCGATCAGAA.

<h3>What is a complementary strand?</h3>

During DNA replication, the molecule unwinds and the two strands are separated. These are the original strands.

Once the strands are separated, the elongation process begins, in which new nucleotides are added to complement each of the original strands.

A DNA molecule grows composed of an old existing strand, which is used to synthesize the new complementary strand.

After DNI replication each new molecule carries an original DNI strand and a new one.

So, the complementary strand is the new one composed of bases that pair the bases from the original strand.

In DNA molecules, Adenine pairs Thymine, and Cytosine pairs Guanine.

In the exposed example,

Original strand ⇒ ATGGGCTAGTCTT

Complementary strand ⇒ TACCCGATCAGAA

How are cyclotrons used to create synthetic elements?

Kipish [7]

Cyclotrons is used to speed up or accelerate creation of synthetic elements. Cyclotrons are also called Particle accelerator which causes the elements to speed up and collide, and fuse with another element called atomic nuclei to produce synthesized or synthetic elements.

What is one main similarly between the digestive system and the respiratory system?

sweet [91]

They are both involuntary systems. Meaning the initial part of the process may be controlled like eating and chewing or holding your breath, but the rest of it is something that just happens and you don't have to think about it. For the most part you don't even think about the breathing. They both obviously keep you alive, but it's because your body takes aspects of each to do so. Removing oxygen from the air and putting it into the blood stream and removing nutrients from food to power cells. Thirdly, they both take something in, use it, and remove the waste.
