1c) If the amino acid sequences in the proteins of 2 organisms are similar, why will their DNA also be similar?
Trava [24]

Answer and Explanation:

Because the DNA sequence determines a protein's amino acid sequence, a gene shared by two closely related organisms should have similar, or even identical, amino acid sequences. That's because closely related species most likely diverged from one another fairly recently in the evolutionary span. Thus, they haven't had as much time to accumulate random mutations in their genetic codes.

What is the fitness advantage for the angiosperm approach to the formation of nutritive tissue?
kiruha [24]
<span>An advantage for the angiosperm approach to the formation of nutritive tissue is in energy conservation.</span> <span>The nutritive tissue is formed via double fertilization in Angiosperms. The advantage of double fertilization is that the plant does not invest energy in seed nutritive tissue until after an egg has been fertilized. This means that endosperm (nutritive tissue) starts to develop and store nutrients after it has been fertilized by a sperm cell.</span> Another advantage is that the endosperm nucleus is very active and <span>divides rapidly, so it forms the nutritive tissue very quickly.</span>

Determine how to make positive and negative ions. Based on your exploration which subatomic particle is positive? Which subatomi
Katena32 [7]

Answer:

Atoms are electrically neutral as a result of having an equal amount of positive (due to the protons) and negative (due to the electrons) charges on it.

An ion generally is an electrically unbalanced atom (i.e an atom with a net charge on it)

A negative ion called an anion is produced when an atom gains an extra electron from a neighboring atom, giving it an extra negative charge. This can be produced by ionization with a radioactive radiation or simply by dissolution.

A positive ion is called a cation and it is produced when an atom loses electron to a neighboring atom. The loss of this electron causes the positive charges to outweigh the negative charges in the atom. Cations can be produced by radioactive radiation ionization of an atom or by simple dissolution.

The subatomic particle that is negative is the 'electron'.

Describe the transformation of energy that occurs during photosynthesis.
Doss [256]

Answer:

Photosynthesis is the process of converting light energy into chemical energy in the form of glucose, in small structures called chloroplasts. The glucose made in photosynthesis is then used during cellular respiration.

geniusboy [140]

Answer:

Obstructive shock.

Explanation:

Obstructive shock may be defined as the shock that are associated with the physical obstruction of the vessels of the heart. The  cardiac tamponade and  Pulmonary embolism are included under obstructive shock.

Thrombosis is the blood clot formation in the blood vessels. This has caused the pulmonary embolsim. This is referred as obstructive shock as the heart vessel has been damaged in this case and also shows the cardiogenic shock in the patient.

Thus, the correct answer is obstructive shock.
