Dakota lives in New Orleans. He knows that scientists have predicted some changes on Earth due to global warming, and he is concerned it will affect his city.
What effects are scientists concerned about in relation to global warming? Choose the two that apply.
A. decreases in temperatures
B. melting of sea ice
C. decreasing sea levels
D. decreases of greenhouse gas concentrations
E. increase in carbon dioxide from melting permafrost
Melting of sea ice and increase in carbon dioxide from melting frozen grounds are effects scientists concern about in relation to global warming. Therefore, option (B) and (E) are correct.
What is global warming?Long-term changes in temperature and weather patterns are referred to as climate change. Although these changes may be natural, human actions have been the primary cause of climate change since the 1800s, mostly as a result of the burning of fossil fuels (such as coal, oil, and gas), which results in the production of heat-trapping gases.
Sea ice loss will expose the cold, dark Arctic water, which will absorb heat instead of reflecting it, accelerating the rate of global warming. Additionally, it will disrupt the ecology of the area, hurting everything from algae to sizable creatures like polar bears and seals that depend on the sea ice for hunting.

Nonvascular plants have never evolved to the size of vascular plants, most likely because they lack Select one: a. a photosynthetic mechanism. b. an efficient mode of respiration. c. an efficient system for conducting water and minerals. d. nutrient and water absorption mechanisms. e. They lack all of these choices.
Answer:
The correct answer is c. an efficient system for conducting water and minerals.
Explanation:
Non-vascular plants lack the internal tubes or vessels that carry water and minerals or nutrients through the entire plant. Most of them are found in humid or submerged places, since this type of environment allows them to absorb water through the surface of their tissues. Non-vascular plants do not grow very tall due to the lack of structures normally associated with vascular plants. Non-vascular plants lack specialized vascular tissue (xylem and phloem) for conduction and internal support of water and food. Metabolites and other nutrients are transferred between and within cells by osmosis, diffusion, and cytoplasmic flow.

2. Plants follow a reproduction pattern called alternate generations. Explain the two processes in alternate generations.
Answer:
Alternation of generations is a type of life cycle by which species alternate haploid (n) and diploid (2n) individuals.
Explanation:
Alternation of generations refers to the life cycle observed in terrestrial plants by which species alternate between haploid (i.e., organisms having a single set of chromosomes) and diploid (2n, i.e., organisms having a single set of chromosomes) generations. Plants alternate between a sporophytic stage and a haploid gametophytic stage. This alternation of generations is accompanied by the alternation between sexual reproduction, where the fusion of male and female gametes from the gametophyte generation produces a diploid zygote that develops into the sporophyte, and asexual reproduction, where spores (generated in the sporangium of the diploid sporophyte) are released and germinate into new individuals.

Jackson, a 4-year-old boy, is unable to get the measles (MMR) vaccine due to a severe allergy to the antibiotic neomycin. Jackson will be starting kindergarten next year and his parents are trying to decide whether to send him to Oak Crest Elementary School, which has an 80% vaccination rate for MMR, or Lincoln Elementary School, which has a 95% vaccination rate for MMR.
Required:
a. What would you advise them and why?
b. Is Jackson at risk of contracting measles? Explain your reasoning.
Answer:
In Lincoln Elementary School.
Explanation:
I advise them to send Jackson to Lincoln Elementary School which has 95% vaccination rate for MMR because there is less chances of having measles to Jackson as compared to Oak Crest Elementary School having 80% vaccination rate for MMR. Yes, Jackson is at risk of contracting measles because of no immunity acquire against measles disease by its body. The vaccine can provides immunity to Jackson from the disease but he can't take it due to allergy.

How many cells do you end up with in Meiosis?
A) 2
B) 1
C) 3
D) 4
Answer:
During meiosis , four daugther cells are produced
Answer:
4 cells. You end up with four cells.
Explanation:
Each daughter cell undergoes meiosis-II, producing two cells. In meiosis-II the separation of two chromatids occur so that equal number of chromatids (in fact chromosome due to duplication of genetic material) goes to each of the daughter cell.
Thus, at the end of meiosis-II, four daughter cells are formed. Each cell has half the number of chromosomes present in the diploid cell.

Tibetans' physiological adaptations make them less likely to suffer from pulmonary hypertension (or high blood pressure). So, the correct option is C.
What do you mean by Adaptations?
Adaptations may be defined as the evolutionary process where an organism becomes better suited to its habitat, in order to survive and reproduce in it.
Tibetans are adapted to high altitudes by producing fewer red blood cells. They have greater hypoxic and hypercapnic ventilatory responsiveness. They have large lungs, and greater lung diffusing capacity. This leads them less likely to suffer from pulmonary hypertension.
Therefore, Tibetans' physiological adaptations make them less likely to suffer from pulmonary hypertension (or high blood pressure).

Briefly explain why DNA replication is semiconservative and discontinuous. Make sure to name the proteins involved in the synthesis of DNA, synthesis of RNA, the removal of RNA and the sealing of the nicks.
Answer:
DNA replication is semiconservative: each new strand has a strand of the parent DNA and another strand of new synthesis. DNA synthesis is discontinuous, since one of the strands, the lagging strand, replicates intermittently within the replication bubble, while the leading strand replicates continuously. For replication, apart from DNA polymerases, requires the action of enzymes that synthesize the primer, DNA ligases, enzymes that are responsible for joining pieces formed of chains, etc. RNA is synthesized through a process called transcription in making a complementary copy of a piece of DNA.
Explanation:
Replication is discontinuous since one of the strands, the lagging strand, replicates intermittently within the replication bubble, while the leading strand replicates continuously. It is bi-directional, because the strand is copied in both directions, and depending on the point of origin and the way it is viewed, a strand can be either discontinuous or continuous. Finally, replication is said to be semi-conservative since the original strands are part of each of the double strands resulting from replication.The unwinding of the DNA and the maintenance of the two separate strands in the replication fork so that the two new strands can be synthesized requires the action of proteins: Gyrase allows the release of the torque tension of the DNA double strand while the helicase separates the strands, allowing the action of DNA polymerases, which are responsible for the inclusion of new nucleotides as the DNA model strand is copied. Finally, the primases allow the incorporation of leader sequences at the beginning of the replication forks, allowing the action of DNA polymerases. DNA ligases seal cuts or nicks (broken phosphodiester bonds). DNA ligase also splices the ends of DNA into duplex regions. Transcription consists of the synthesis of RNA taking DNA as a template and means the passage of the information contained in DNA to RNA. The transfer of information from DNA to RNA is carried out following the complementary rules of the nitrogenous bases. When the entire strand has been copied, at the end of the process, the RNA chain is free and the DNA is closed again, by pairing of its complementary chains.

An echinoderm that is covered with movable spines and that eats seaweed
sea urchin
sea star
brittle star
sea cucumber
echinoderm
Answer:
sea urchin
Explanation:
An echinoderm is an invertebrate animal (without backbones) that belongs to the Echinodermata group. Members of the echinoderm group are characterized by their possession of a star-shaped and spiny-skinned morphology. They are found strictly in marine habitats. They include sea urchins, sea cucumbers etc.
According to this question involving an echinoderm that is covered with movable spines and that eats seaweed, this describes a SEA URCHIN. This is due to the possession of the MOVABLE SPINES by sea urchins. Sea urchins, like other echinoderms, are predatory and feed on seaweed (algae) as well.
