The diagram shows the general structure of a lipid, which consists of two main parts. mc006-1.jpg Which part is circled? alcohol group fatty acid carboxyl group unsaturated lipid

Answers

Answer 1

Answer:

The circle part of the structure is the CARBOXYL PART.

Generally, lipids are naturally occurring molecules and they serve as sources of high energy value in humans. Basically, lipids are synthesized from glycerol and fatty acids. The number of fatty acids attached to the glycerol determine the type of lipid that the molecule is. The glycerol is a type of alcohol and is made up of hydroxyl ions. lipid bio molecules are soluble in non polar solvent and insoluble in water.

If two eukaryotes participate in lateral gene transfer what will this do to the overall genetic variation of thespecies?
A) Nothing, the genetic variation will stay the same.
B) The genetic variation will decrease.
C) The genetic variation will increase.
D) This type of gene transfer is impossible in eukaryotes.

Answers

Lateral gene transfer, also known as horizontal gene transfer, increases genetic diversity and plays a big role in evolution of single celled organisms.

Answer:

The correct answer would be C) The genetic variation will increase.

Horizontal or lateral gene transfer refers to the transmission of genetic material between two different genomes which is distinguished from a transfer of genetic material from parent to the offspring that is, vertical gene transfer.

For example, transformation, transduction, and conjugation result in horizontal gene transfer in bacteria.

It increases genetic variation of the population and plays important role in adaptation as well as evolution.

A group of scientists are studying the effects of different fertilizers on the growth of pea plants. They began their study with 10 pea plants. They gave each plant a different type of fertilizer and tracked their growth over a period of 2 months. What’s the independent variable in this experiment?

Answers

The answer is a type of fertilizer.

An independent variable is variable that is not affected in the experiment. It is what experimenter controls. On the other side, a dependent variable is called dependent because it depends on the independent variables. It is what is affected during the experiment.
In this case, the growth of pea plants depends on different types of fertilizer. So, the growth of pea plants is the dependent variable and different type of fertilizer is the independent variable.

The _____ theory is an evolutionary concept that suggests that behaviors that help an organism survive are passed on while weak behaviors are lost.genetic drift
gene flow
optimality

Answers

Answer:

Option B, Gene flow theory

Explanation:

Gene flow induces genetic pool in a particular species of organism. It also leads to speciation and therefore allows species belonging to a particular species to mate and produce fertile offspring with distinctive genetic trait as compared to their parents.

This new set of genes created by frequent mating leads to creation of genepool. Genepool allows the fittest genetic trait to grow further so that the fittest individuals are produced and in this way the weak behaviour traits are lost with time.

Hence, option B is correct.

Answer:

gene flow

Water harvesting, the collection of rainfall and run off for future use, has been practiced for thousands of years; but in some regions where it was previously used it has been forgotten. In countries facing huge problems with land erosion due to runoff, governments have been encouraging the implementation of this technique. The implementation is important for more than pervention of water erosion . What other benefit might water harvesting have in these areas

Answers

In some areas where water harvesting technique is applied, gains benefit in various ways such as water supply for agricultural purposes and another water usage for the day to day activities like for bath, washing, and cleaning.
More importantly, the use of this technique enables the area to have a clean drinking water. Water is safe to drink because it includes filtration.

Answer:

Haciendo almacenamiento y excavación en un área grande, mientras que los estanques son los sistemas utilizados para recolectar agua.

Explicación:

El sistema artificial que el hombre usa para recolectar agua es la construcción de un gran almacenamiento de concreto y la excavación de un gran terreno que recolecta agua de lluvia y puede ser utilizado por la gente para su uso diario, mientras que por otro lado, los estanques son el sistema natural donde el agua del la lluvia se acumula naturalmente. Esta agua es utilizada por la población que vive alrededor de ese estanque. Ambos sistemas proporcionan agua para el uso diario, como lavar, beber y cocinar, etc.
