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.

Explanation:
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).
In fruit Flies a white eyed female is crossed with a red eyed male. What are the changes the offspring will be a white eyed male?
Answer:
the chances of the offspring having white eyes is 50%
Explanation:
i used a punnet square to calculate the output:)
Answer:
25%
Explanation:
There's a 50% chance of the offspring being male & 50% chance female. The genotypes must be co-dominant otherwise their question doesn't give enough information to get an anwser. Also a 50/50 chance of red/white, so added together a 25% chance.
Also, the funny thing is that remember this from 7th grade so you must be reviewing things that evreyone learned a long time ago but forgot.

How in the world r wolfs endangered?!!!! They hunt in packs so humans would at least need a semi-automatic riffle or something like that and before he/she kills all the wolfs more than likely they will be died so will give u all my points
Answer:
Humans are a big reason for this issue. Things such as pollution, hunting, construction, and animal testing all effect the wolves population. Their food is hunted by humans so its harder for them to hunt, humans tear down trees and take over ground so theres less places to live, they might eat things like plastic because people litter, and things like dangerous weather can harm these animals.

: propels food through the digestive tract. : lines internal and external body surfaces. : conducts electrical impulses. : transports oxygen to the body tissues. : functions in secretion and absorption. : pumps blood. : stores fats and minerals.
Answer:
1. Muscle tissue.
2. Epithelial tissue.
3. Nervous tissue.
4. Connective tissue.
5. Epithelial tissue.
6. Muscle tissue.
7. Connective tissue.
Explanation:
A tissue can be defined as a group of cells that are structurally similar and in close proximity. Tissues are generally responsible for performing specific functions in living organisms such as humans, animals and plants. Therefore, tissues in living organisms function together as a unit.
There are four main types of tissues and these includes;
I. Connective tissue.
II. Epithelial tissue.
III. Muscle tissue.
IV. Nervous tissue.
In this scenario, the various types of tissues are matched with their functions as follows;
1. Muscle tissue: propels food through the digestive tract. It is mainly performed by peristalsis.
2. Epithelial tissue: lines internal and external body surfaces. It also referred to as epithelium and it comprises of sheets of cells.
3. Nervous tissue: conducts electrical impulses. A neural circuit can be defined as a group of neurons in the body of a living organism which are interconnected by synapses to perform specific functions when they're activated.
4. Connective tissue: transports oxygen to the body tissues predominantly through the Erythrocytes (red blood cells).
5. Epithelial tissue: functions in secretion and absorption.
6. Muscle tissue: pumps blood.
7. Connective tissue: stores fats and minerals.
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.
6. What regulatory processes would your body use if you were trapped by a blizzard in an unheated, uninsulated cabin in the woods (or in a heat wave with no air conditioning)
Answer:
Shivering and sweating.
Explanation:
A prolonged exposure to extreme cold environment would activate the brain's heat-gain center. Your brain's heat-gain center causes shivering in order to increase our muscle contraction which leads to warming of our body. Increase sweating is the regulatory processes our body use if it experience very high temperature. In order to regulate internal temperature of body, our body remove water which takes up heat with itself to lower th internal temperature.

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.
