Answer:
Another factor besides distance from the sun would be "atmospheric composition".
Explanation:
Other than distance from the sun, atmospheric composition affects the temperature of a planet. Atmospheric composition is the amount of energy that gets to the exterior of a planet. The energy that gets to the exterior of a planet, affects the temperature.
Assume a population of deer has a crude birth rate of 36 per 1,000/yr, a crude death rate of 20 per 1,000/yr, an immigration rate of 15 per 1,000/yr, and an emigration rate of 8 per 1,000/yr. What is the population growth rate
Answer:
0.023%
Explanation:
The Population growth rate is a change in population with time taken into consideration. It can be expressed with the formula
[tex]N/t[/tex] where N is the total change in the population size, and t is time.
When immigration and emigration are factored in, we now have the formula;
[tex](CBR +I) - (CDR + I)/1000[/tex]
[tex]= (36 + 15) - (20 + 8) = 51 - 28= 23\\\\expressing as a percentage of the population gives us,\\\\23/1000=0.023%\\\\[/tex]

Which of these is most likely to cause increasing numbers of severe weather
events?
A. Slowing of the thermohaline circulation
ОО
B. Increasing salinity
c. Decreasing temperature
O D. Falling sea levels
SUBMIT
Answer: What is most likely the cause of the increasing numbers of severe weather events is A. the slowing of the thermohaline circulation.
Explanation: Thermohaline circulation is hard to explain, but it is important in giving heat to the polar regions. The six main components that determine the weather are temperature, atmospheric pressure, cloud formation, wind, humidity, and rain. A small change in any of these components can result in an entirely new weather pattern. As mentioned in the question, slowing the thermohaline circulation would very likely increase the number of severe weather events. What I just said, I took the test, and the answer is A.
Slowing of the thermohaline circulation is most likely to cause increasing numbers of severe weather events. Thus, the correct option will be A.
What is Thermohaline circulation?Thermohaline circulation is a part of the large-scale ocean circulation which is driven by the global density gradients that are created by the surface heat and freshwater fluxes.
Thermohaline circulation generally plays an important role in the process of supplying heat to the polar regions. Therefore, it influences the rate of sea ice formation near the poles region, which in turn affects other aspects of the climate system such as the albedo, and thus also include solar heating, at high latitudes.
Therefore, the correct option will be A.

In 1998, paleoanthropologist Rick Potts published an article in The Yearbook of Physical Anthropology, a peer-reviewed journal. The article was titled “Environmental Hypotheses of Hominin Evolution.” In his paper, Potts claimed that great variations in environmental conditions over time were responsible for the adaptability of humans and the success of our species. Which would most likely be found in his paper? a review of modern human anatomical structure evidence of changing environmental conditions, with references the reasons competing hypotheses are wrong his opinion of what will happen to the survival of the human race
Answer:
Dr. Potts used environmental data to support environmental hypotheses capable of explaining human evolution
Explanation:
In this paper, the author stated that environmental factors have been fundamental for the emergence of adaptive traits during human evolution. In consequence, Dr. Potts explained how particular environmental factors and habitats might have shaped human evolution. For example, it has been hypothesized that dry savanna vegetation might have been a key environmental factor associated to the emergence of human traits including, among others, bipedality, making of tools from stones, the development of human brains, etc. In order to prove this hypothesis, the author recorded environmental data from different regions in Africa (Olorgesailie, Olduvai, Turkana, Zhoukoudian, etc), where it is believed that first hominids evolved about 6-8 million years ago.

Which type of cell can duplicate indefinitely?
Answer:
Embryonic stem cells
Explanation:
Answer:b
Explanation:
Mutations in region B and region D give the same results - when either of these regions is mutated, the operon is expressed under all conditions (called constitutive expression). You hypothesize that region B is the operator region and that Region D is the repressor protein. To test your hypothesis, you create two partial diploid lines by introducing a F' plasmid with a wild-type lac operon: Strain 1: F' A B C D E / A B- C D E Strain 2: F' A B C D E / A B C D- E What experimental results would be predicted by your hypothesis
Answer:
As it is given in the question that region D is the repressor protein and operator region is region B then the The repressor region D form a protein that will bind to the operator region B and leads to inhibition of the transcription. So, the repressor protein will not repressed a mutant operator and the lac gene will express itself constitutively.
Strain 1: F' A B C D E / A B- C D E
In this strain the mutant opertor gene is present so, it will not repressed by F' as it will not be able to bind. Hence, the lac gene expression is constitutive.
Strain 2: F' A B C D E / A B C D- E
In this strain there is two protein produced by the F' plasmid mutated repressor protein, and a non-mutated repressor protein. As we know mutated repressor will not bind to operator gene and still expression will take place but here a extra not mutated non-mutated protein is present and the repressor protein from F' will bind to the operator region B and thus repress the expression of gene in it.
Desribe the structure of amino acids including what makes amino acids different from each other
Answer:
1) Amino acid contains a central carbon atom attached to: an anime group, carboxyl group, hydrogen atom and a side chain
2) The side chain of each amino acid differentiates from one another
Please find the description below
Explanation:
Amino acids are monomeric chemical compounds that forms the make up of a protein. Amino acids , like every other chemical compound, have a structure. Amino acids have two functional groups i.e. amine group (-NH2) and carboxylic acid group (-COOH).
All amino acids, which are naturally 20 in number have basic parts in common namely: 1) a central carbon atom, also called the alpha carbon 2) a hydrogen atom 3) an amine group i.e. (-NH2) 4) a carboxyll group i.e. (-COOH)
These are the basic parts of all amino acids, however, the difference between the amino acids is found in the series of different atoms called Side chains or R group that attach to the alpha carbon. These R group makes each amino acid specific and different. For example, a side chain containing sulphur (CH3-S-(CH2)2) is the R group of methionine. Each amino acid has a different side chain attached to the basic structure listed above.

Explanation:
Which of the following best describes the flow of energy in the Everglades food web shown below? (4 points) Diagram for an everglades food web. The food web contains the following organisms: American alligator, egret, raccoon, carp, Key deer, insects, Southern leopard frog, mangrove, and sawgrass. Mangrove is at the bottom of the food web, with arrows pointing to Key deer and insects. Sawgrass is also at the bottom of the web, with an arrow pointing to insects. Key deer, insects and Southern leopard frog are on the next level up. The Key deer has an arrow pointing to American alligator. The insects point to egret, carp, and Southern leopard frog. The Southern leopard frog points to the American alligator and the raccoon. The egret, carp and raccoon all points upward toward the American alligator. The carp also points to the egret. The American alligator is at the top of the food web. Mangrove → insects → carp → American alligator; about 90 percent of the energy in one trophic level is transferred to the next trophic level. Sawgrass → insects → Southern leopard frog → raccoon → American alligator; about 10 percent of the energy in one trophic level is transferred to the next trophic level. American alligator → carp → insects → mangrove; about 10 percent of the energy in one trophic level is transferred to the next trophic level. Egret → insects → mangrove → key deer → American alligator; about 90 percent of the energy in one trophic level is transferred to the next trophic level.
Answer:
Although there is no diagrammatic representation of the food web but the question can be answered based on the provided information. The answer is:
Sawgrass → insects → Southern leopard frog → raccoon → American alligator; about 10 percent of the energy in one trophic level is transferred to the next trophic level.
Explanation:
Food web is an interconnected food chain i.e. a series of food chains clustered together. A food web represents the various ways one organism can feed on another in a cycle. Since a food web consists of many food chains, energy is transferred when one organism feeds on another (flow of energy).
Just like a food chain, a food web begins with a PRODUCER, which is an organism capable of producing its own food via photosynthesis. This is the case of mangrove and sawgrass in this depicted food web as they are both producers and hence, must start the food web i.e. be at the bottom of the food web. Organisms called CONSUMERS feed on producers and one another to obtain energy. Consumers can be primary, secondary or tertiary depending on the organism they feed on. Primary consumers feed directly on producers, secondary consumer on primary and tertiary consumers on secondary, in that order.
This accounts for why the American Alligator is at the top of the food web because it is a tertiary consumer.
However, as organisms feed on one another, only about 10% of the available energy is transferred because most of the energy (about 90%) has been used for metabolic processes and hence, lost as heat.
Therefore, the best description for the flow of energy in the Everglades food web is:
Sawgrass → insects → Southern leopard frog → raccoon → American alligator; about 10 percent of the energy in one trophic level is transferred to the next trophic level.
Sawgrass is the producer and must begin the energy flow, followed by a primary consumer (insect). Feeding continues in that order until the tertiary consumer (American alligator) is reached.
Answer:
b) Mangrove → insects → Southern leopard frog → raccoon → American alligator; about 10 percent of the energy in one trophic level is transferred to the next trophic level.

Explain why mutations that replace S/T/N residues with A/L/W residues in the N-terminal region of transmembrane proteins that function as cell surface receptors could significantly disrupt that utility of these proteins as receptors.
Answer:
Serine (S), Threonine (T) and Asparagine (N) are primary binding sites of carbohydrates, and thereby they are required to form glycoproteins (i.e., glycosylation products)
Explanation:
A transmembrane protein (TP) is a particular type of protein that crosses the cell membrane in order to enable the movement of ions and molecules. Transmembrane proteins are divided into alpha-helical and beta-barrel proteins. The N-terminal region of transmembrane glycoproteins can be required for N-linked glycosylation, which is an enzymatic mechanism capable of attaching oligosaccharides to proteins in order to form glycoproteins (glycans). N-linked glycosylation is a posttranslational protein modification that has distinct functions depending on the cell type and the protein region involved in such modification. For example, in the surface of immune cells, the N-linked glycans are capable of dictating the migration pattern of these cells.

In a cell with defective chaperones, Question 14 options: proteins would not be able to exit the ribosome. the concentration of misfolded proteins would be higher than normal. proteins would not be delivered to their appropriate cellular locations. ribosomes would not associate with the endoplasmic reticulum.
Answer:
the concentration of misfolded proteins would be higher than normal.
Explanation:
Chaperones proteins are required for the correct protein folding of proteins. These proteins were first discovered in bacteria. The level of chaperones is increased under thermic stress conditions, it is for that reason that they are also known as heat shock proteins (Hsp). For example, Hsp70 is a chaperon protein constitutively expressed under stress conditions that is involved in the folding of protein precursors and the refolding of misfolded proteins. In humans, Hsp70 is encoded by the HSPA1A gene, and its increased expression level is related to different health problems including neurodegenerative diseases, cerebral ischemia and epilepsy.

B. Oceanic crust is denser than continental crust.
C. Oceanic crust is less dense than continental crust.
D. Oceanic crust is older than continental crust.
Answer:
B.) Oceanic crust is denser than continental crust.
Explanation:
Oceanic crust is denser, so it is subducted under the continental crust. The less dense magma then rises up through the continental crust, then it's further increasing the size of the continental crust and then maintaining it's lower density than the oceanic crust, which then causes subduction.
