Answers

Answer:

The nature of the indicated covalent bond is polar.

Explanation:

The given diagram is the Lewis structure of Methylamine which has the formula, CH₃NH₂.

In order to know that it is polar, we will discover that in the Lewis structure there are unpaired electrons in the central atom. Also, the bond that exists between the hydrogen and nitrogen shows that it is polar.

CH₃NH₂ is seen to have two charged ends that are opposite and the bonds that exists between hydrogen and nitrogen, which makes it a polar molecule.

The electronegativities of carbon, hydrogen and nitrogen can also be used to determine its polarity.

Which event in meiosis increases genetic variation within a population?
A. DNA condenses to form chromosomes.

B. Segments of chromosomes cross over.
C. Chromosomes duplicate themselves.
D. Chromosomes form pairs.

Answers

Answer:

Because of recombination and independent assortment in meiosis, each gamete contains a different set of DNA. This produces a unique combination of genes in the resulting zygote. Recombination or crossing over occur during prophase 1

What is the resource in the plant that aphids eat?

Answers

Answer: Aphids are herbivores. They suck plant juices out of the leaves, stems, or roots of plants. The juices they drink often have much more sugar than protein. Aphids have to drink so much sugary juice to get enough protein that they excrete a lot of the sugar.

Explanation:

I can confirm that it is correct.^
Aphids feed on soft stems, branches, buds and fruits. They pierce the stems and suck the nutrient rich sap from the plant leaving damaged flowers and fruits :)

The two activities that can help to increase the biodiversity of the Amazon rainforest are as follows:

Creating more urban settlements.Increasing agricultural run-off.

Thus, the correct options for this question are A and C.

What is Biodiversity?

Biodiversity may be defined as the sum total of all the variety of living organisms that are present on the earth's surface. In a more simple sense, it is also characterized by the number of species of all living organisms exist on the earth.

Mining and resource extraction disrupts the quality and quantity of resources that living organisms utilize in order to enhance biodiversity. The introduction of non-native species utilizes all resources present in the area of native species and furnishes the process of competition. Creating protected land areas restricts the resources at specific parts/locations.

Therefore, the correct options for this question are A and C.

someone may ask you to distill a complicated idea into a brief summary that gets right to the point. how does this relate to distillation in chemistry

The more volatile liquid (the liquid with the lower boiling point) will typically evaporate first and the vapor will pass into a ... the refluxing liquid can condense, re-evaporate, and condense again, essentially distilling the ...

Explanation:

Distilling a complicated idea into brief summary that gets right to the point relates with distillation in chemistry in that both requires breaking a complex idea/substance into smaller component pieces.

In chemistry, distillation is a technique used for separating a liquid mixture into its components by allowing each component to boil, evaporate off the mixture, and then allowed to condense.

Because the each component of a mixture has different boiling point, this attribute is applied in distillation. The mixture is placed in a distiller and heated. At their respective boiling temperature, each component evaporates off the mixture and condenses at a collection point by a cooling water.

This is what it means when a complicated idea is being asked to be distilled. Such idea is to be broken down into smaller, concise ideas that can easily be executed as part of the whole idea.

To grow, plant cells must produce new components of the cell membrane, including phospholipids and membrane proteins. Components of the cell membrane are most likely synthesized in which of the following cellular structures in a plant cell?

The cell membrane (plasma membrane) is describe as a highly selective
barrier composed of alipid bi-layer. This structure plays an important role
in moving molecules across the cell membrane in order for the cell to
maintain homeostasis. If the cell is unable to take in the materials it needs
or remove vwhat it does not need, the cell may die. This inability of cells to
maintain homeostasis may cause sickness or even death of an organism.
Why is it important that the cell membrane is highly selective?
O So that the cell wall is stabilized and maintains its rigidity.
O To prevent certain ions and molecules from entering or exiting the celI.
O So that proteins and lipids can attach to the membrane where needed.

Mitosis produces which cell type?
haploid
diploid
chromosome
gamete

Answers

Answer:

b, diploid.

Explanation:

Mitosis produces two diploid somatic cells, genetically identical to each other and the parent cell.

Mitosis produces diploid cells (option B)

What is Mitosis?

Mitosis is a process of cell division observed in cells. Its primary purpose is to ensure that the genetic information, in the parent cell is equally distributed among the resulting daughter cells.

During mitosis the process generates cells that are diploid, meaning that the number of chromosomes in the parent cell is the same as the number in the resulting daughter cells.

In contrast haploid cells have half the number of chromosomes found in cells. Examples of haploid cells include sperm and eggs which are known as gametes.

Notably, we can conclude that mitosis produces diploid cells (option B)

Answer:

The main reason for the decrease in trillium is the large number of deer in the forest that are eating the trillium. The author cites a research study performed by scientists as evidence to support her claim. In this study, researchers planted two fields, each containing garlic mustard and trillium. One was left open to deer, and the other was fenced off. Scientists kept track of the fields for several years. They found that trillium was able to regain much of its original space in the protected field. In the unprotected field, there was still more garlic mustard because the deer ate the trillium. The author also states that similar research studies have been conducted in many forests across the United States, and they all reveal similar results.
