Answer:
tetracycline
Explanation:
When the DNA insert is ligated in Pstl site, the ampicillin gene is disrupted while tetracycline gene is still intact.
- If the bacterial colony is growth in a medium with only ampicillin, only the cells that contains the plasmid with the insert will grow.
- If the bacterial colony is growth in a medium with only tetracycline, the cells which have incorporated the plasmid will survive. We cannot distinguish between cells with plasmid + insert and plasmid alone.
- If the bacterial colony is growth in a plate with ampicillin + tetracyclin, only the cells with the plasmid without the insert will grow.
Therefore, to ensure that the cells of a bacterial colony contains the plasmid, they have to be seeded in a plate with tetracycline.

why do plants need to continually take in carbon dioxide, oxygen, and water from the environment?
Answer:
Oxygen is needed to break the sugar into carbon dioxide, releasing energy the plants can use to stay alive. However, plants also take in energy from the sunlight, carbon dioxide from the atmosphere, and water from the soil.
Explanation:
They use all of them to make sugar and release oxygen.

Choose TWO human activities that can help to increase the biodiversity of the Amazon rainforest
A
creating more urban settlements
B
mining and resource extraction
C
increasing agricultural run-off
D
practicing sustainable agriculture
E
creating protected land areas
TI
introducing non-native species
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.

Gregor is planting pea plants in his backyard. Some of the plants are tall and the rest are short. Some of the plants are yellow and the rest are green. The numbers of different plant types are in the ratio[{Tall green}:{Tall yellow}:{Short green}:{Short yellow} = 8:5:2:1. If there are 1080 green plants, then how many total plants are in Gregor's yard?
Answer: 1732
Explanation:
infer short, yellow are recessive
8TG, 5Tg, 2tG, 1tg
proportion of green plants = 10/16
so total plants = 1080*16/10 = 1732

According to the author, what is the main reason for the decrease in trillium in the forest? What evidence does she give to support her claim?
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.

What are the harmful effects of pteridophytes?
These species can spread rapidly with negative consequences for native species. Invasive plant species have an impact on the diversity of local species, they affect water availability and damage the quality of soil nutrients. Once an alien plant has invaded a habitat, it changes the conditions of that environment.
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.
O To allow movement of materials in and out of the cel.
Answer:
O To prevent certain ions and molecules from entering or exiting the celI.
Explanation:
The cell needs to keep a constant chemical composition on the inside in order to mantain homeostasis

Mitosis produces which cell type?
haploid
diploid
chromosome
gamete
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)

polar
non-polar
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.
