this is not my answer I found it from someone else but I hope it helps!

1)The simplest structure is cubic system like simple cubic ,body- centered cubic and face centered cubic in the crystal system.

2)Yes, all minerals have crystal structures because minerals have definite crystal structure. Minerals are solids that are formed naturally through the inorganic processes. some mineral properties are density, shape, color, and hardness.

3) minerals are the naturally occurring inorganic substances which have ordered atomic arrangement, they are not made by humans that's why we can't predict the specific structure of majority of minerals.

Random changes in allele frequency in a population are called:

kogti [31]

Random changes in allele frequency in a population are usually called genetic drift. The reason why this is the answer is because it is a very specific word which is used to describe exactly that - random changes in allele frequency.

All the other cases; answers, here aren't correct and don't apply.

How many atp equivalents are consumed in the conversion of each of the following to a glucosyl residue in glycogen?

Nina [5.8K]

<h3><u>Answer;</u></h3>

Dihydroxyacetone phosphate - 1

Fructose-1,6-bisphosphate - 1

Pyruvate - 13

G-6-P - 1

<h3><u>Explanation;</u></h3>

1) Dihydroxyacetone phosphate = 1

G1P + GTP --> UDPG + PPi two P is equivalent to 2 ATP --->2 ADP + Pi) Therefore, two ATP equivalents - but UDP is the product and only one P needed

2 DHAP --> F1,6-BP -->F6P --> G6P -->G1P -->UDPG --> glucosyl residue

2) Fructose 1,6-bisphosphate = 1

3) Pyruvate = 13

2 pyr + 2 ATP --> 2 OAA

2 OAA + 2 GTP --> 2 PEP

2 PEP --> 2 2PG --> 2 3PG

2 3PG + 2 ATP --> 2 1,3 BPG

2 1,3 BPG + 2 NADH --> 2 G3P

2 NADH = 6 ATP

2 G3P --> DHP + G3P --> FDP -- > F6P + P

F6P --> G6P --> G1P

G1P + UTP --> UDPG + PP

4) Glucose-6-phosphate = 1

G6P -->G1P G1P + UTP --> UDP-GLC + 2 Pi

UDP-Glc + glycogen --> glycogen+ 1 Glc

Give at least three facts autotrophs and heterotrophs on earth are true?

White raven [17]

Answer:

Autotrophs are usually defined as those that can prepare their own food by carrying out the process of photosynthesis, but heterotrophs cannot prepare their own food and are directly dependent on the autotrophs for food. Examples of autotrophs are plants and trees, and examples of heterotrophs are animals and human beings.

Autotrophs are the lowest organisms in the trophic level, where they produce the food for the consumers (heterotrophs). On the other hand, the heterotrophs lie above the autotrophs and when they consume their food, they obtain only 10% of the energy, and the remaining energy is released into the environment.

Autotrophs can make organic substances by the use of inorganic molecules, but heterotrophs cannot make these substances. They are only dependent on the molecules prepared by these autotrophs.

Thus, these are three of the facts regarding autotrophs and heterotrophs existing on earth that are true.
