Question 1 Negative Forcings: increase the amount of sea ice at the north pole for instance. O increase the growing season. increases the amount of energy in the Earth's budget. decrease the amount of energy in Earth's energy budget.
Answer:
increases the amount of energy in the Earth's budget.
Explanation:
Increase occurs in the amount of sea ice at the north pole leads to increases the amount of energy in the Earth's budget because this sea ice reflects the solar radiation back to space. Sea ice has a bright surface which causes 80 percent of the solar radiation reflected back into space. As sea ice melts in the summer, it exposes the dark ocean surface which leads the ocean to absorbs 90 percent of the sunlight which heat up the oceans, and increase in the temperature occurs causes more melting of ice so increasing sea ice is good for the earth.

What did Gregor Mendel do to study different characteristics in his genetics experiments?
Gregor Mendel, through his work on pea plants, discovered the fundamental laws of inheritance. He deduced that genes come in pairs and are inherited as distinct units, one from each parent. Mendel tracked the segregation of parental genes and their appearance in the offspring as dominant or recessive traits.
Explain how DNA supports the theory of evolution?
Answer:
Because there are tens of thousands of genes in humans and other organisms, DNA contains a tremendous amount of information about the evolutionary history of each organism. ... It determines evolutionary relationships among organisms, and it indicates the time in the past when species started to diverge from one another.
In a good experimental design, the part of the experiment that is intentionally changed is the
A dependent variable.
B independent variable.
C constant
D control
Constants never change.
Controls typically don't change or they are done by standard means
(like in an experiment where you water plants with sodas, the plant you use water with is the control)
Dependent variables are the outcome of the experiment. This is the result of changing something.
Independent variables are what you are testing. A independent variable is something that is intentionally altered.
easy way to remember it is that dependent variables depend on what other variables are. so you cant change a dependent variable, but you can change the other variables.
Living things_______in response to changer in there environment. 1.evolve. 2.fossils. 3.extinct. 4.species. Can some tell me which one it is?

HELP ME PLZZZZZZZZZZZZ Clark decides to measure the volume of a rock he found outside. He fills a graduated cylinder with water to 30mL. Places the rock into the water and the water level rises to 37mL. What is the volume of the rock?
Answer:
The correct answer is - 7 cc or ml.
Explanation:
Given:
The volume of water in a graduated cylinder = 30 mL
The volume of rock = ?
Final volume = 37 ml
Formula:
If an object is placed in water, then the amount of water that is displaced or increased by submerging the object is equal to the volume of the object.
Vi + Vo = Vf
Vi = initial volume
Vo = volume of object
Vf = final volume
Solution:
Placing the values in formula -
30 + Vo = 37
Vo = 37 - 30
Vo = 7 ml or cc.

You transform a population of cells with a transgene and isolate a cell line that has integrated the gene into its genome, but in which the gene is not expressed. Speculate as to what may be preventing the gene from being expressed. Describe two ways to test this possibility.
Answer:
The transgene could be silenced by: 1- epigenetic mechanisms (e.g., DNA methylation, histone deacetylation, etc.), and 2-the RNA interference (RNAi) pathway
Explanation:
Epigenetics refers to the heritable changes caused by the activation and deactivation of genes without changing the DNA sequence. Epigenetic mechanisms include 1-DNA methylation on cytosine residues, and 2-modifications on amino acids in the tails of histone proteins (e.g., methylation, acetylation, ribosylation, phosphorylation, etc). These two epigenetic mechanisms can modify DNA structure and thus alter the accessibility of transcription factors, thereby suppressing gene/transgene expression. Moreover, the RNA interference pathway (RNAi) is a naturally occurring mechanism capable of suppressing gene/transgene expression both at transcriptional and post-transcriptional levels. The RNAi mechanism is triggered by regulatory non-coding RNAs (ncRNAs) such as, among others, long non-coding RNAs (lncRNAs) and small ncRNAs (e.g., miRNAs, piRNAs, siRNAs, etc). In this case, for example, DNA methylation on promoter sequences could suppress transgene expression, thereby methods to measure DNA methylation can be used to test this possibility (e.g., bisulfite genomic sequencing). Moreover, miRNAs that bind to the messenger RNA of the transgene could also inhibit its expression by triggering the RNAi pathway (e.g., mRNA degradation), thereby methods to measure mRNA levels can be used to test this possibility (e.g., RT-PCR).
A team of marine scientist are studying biotic and abiotic factors that affect the stability of a
deep-sea ecosystem. The scientist discover a new species of fish that eats other fish and
decaying matter. Which of these DOES NOT describe the newly discovered fish?
(4 Points)
Decomposer
O Predator
O Producer
O Consumer
Answer: it is not a Producer
Explanation: it is a Decomposer a Predator and a and it is a Consumer
The one that does not describe the newly discovered fish is "producer," which is the third option, as producers are organisms that can produce their own food through photosynthesis or chemosynthesis.
What is a producer?Producers are organisms that can synthesize their own organic molecules from inorganic substances using energy from the environment, such as sunlight or chemical energy. This process is known as photosynthesis or chemosynthesis, depending on the source of energy used. Examples of producers include plants, algae, and some types of bacteria, while on the other hand, consumers are organisms that obtain their energy and nutrients by consuming other organisms. Consumers can be classified into different types based on their feeding habits.
Hence, the one that does not describe the newly discovered fish is Producer, which is the third option.

Your job is to classify a newly discovered animal species. Your initial studies reveal that your specimen has tissues, organs, and a head; has no body cavity or segmentation; and has bilateral symmetry. To what phylum does this animal belong
Answer:
Platyhelminthes
Explanation:
Platyhelminthes (phylum Platyhelminthes), also known as flatworms, are bilaterian, unsegmented and soft-bodied invertebrates. Platyhelminthes are hermaphroditic organisms with internal fertilization. In addition, this group shows a series of characteristics including 1-a ladder-like nervous system, 2-presence of parenchyma in the body cavity, and 3-flame cells, i.e., specialized excretory cells that function like a kidney. Platyhelminthes can be divided into three groups: Turbellaria (generally found in freshwater), Trematoda (generally parasitic), and Cercomeromorpha (exclusively parasitic).
