There are the same amount of carbon atoms on Earth now as there were in the past, but there are more in the atmosphere ever before. What explanation do you have for this?
The global average atmospheric carbon dioxide in 2019 was 409.8 parts per million (ppm for short), with a range of uncertainty of plus or minus 0.1 ppm. Carbon dioxide levels today are higher than at any point in at least the past 800,000 years.The carbon cycle describes the process in which carbon atoms continually travel from the atmosphere to the Earth and then back into the atmosphere. Since our planet and its atmosphere form a closed environment, the amount of carbon in this system does not change.

Which of these limiting factors is likely to be more plentiful in area A than in
area B?
A. Flooding
B. Disease
C. Shelter
D. Predators
Based on the given information, it is likely that the limiting factor more plentiful in Area A than in Area B is "C. Shelter.
What are limiting factors?Limiting factors are factors that restrict the growth, distribution, or abundance of a population or organism within an ecosystem. These factors can be biotic (such as competition, predation, or disease) or abiotic (such as temperature, water availability, or nutrients).
The presence or absence of limiting factors can affect the carrying capacity of an ecosystem, which is the maximum population size that the ecosystem can support over time. Understanding limiting factors is important in ecology and conservation biology, as they can affect the health and sustainability of ecosystems and species.
The limiting factor more plentiful in Area A than in Area B is "C. Shelter." This is because the population in Area A consistently shows a higher number of individuals over time, which suggests that there is more suitable shelter or habitat available to support the growth of the population

Which of the following suggests what happens when a mutation occurs in an organism? Select one:
Genes begin to appear in different individuals of the population all at once.
The organism develops new traits as a result of using a particular body part.
New traits appear from changes in the instructions given to the cell by the DNA. Useless traits are removed from the organism due to the loss of nucleotides
Answer:
New traits appear from changes to the DNA..
Explanation:
A mutation is when DNA is changed or altered in some way, causing it to tell the cells to do something different from what they usually do such as growing a body part a certain way, or making skin regenerate a certain way. some mutations are specific to one individual person or thing, other mutations are passed down through generations and become a new normal for the species. new diseases such as viruses are often caused by the virus mutating...this is how we have so many different strains of the flu...

The chart below demonstrates the number of genetic differences between 9 species. Which two species are least closely related to each other according to the information provided?
Hi. You did not submit the chart to which this question refers, which makes it impossible for it to be answered. However, I will try to help you as best I can.
Generally speaking, we can state that the two species that are less genetically related are those that present more genetic differences between them. This is because the number of genetic differences is greater in species that have no genetic relationship, or that have a very weak genetic relationship.
In this case, to answer this question, you need to assess which two species, shown on the chart, have the greatest number of genetic differences between them.

if humans began hunting and driving the great barracuda to extinction how would this affect the ecosystem (answer should discuss biodiversity, food webs, and food chains)
Answer:
Generally considered to be the tertiary consumers (top level of the food pyrmaid), barracuda feed on an array of preys including grunts, groupers, snappers, small tunas, mullets, killifishes, herrings, and anchovies. By feeding on these marine organisms, barracuda prevent them from increasing in number.
Now let's barracuda's number starts decreasing due to hunting and other reasons. This will result in other primary and secondary consumers to increase in population. An increase in the number of primary and secondary consumers in the food chain will result in a decreasing number of plants, i.e. the number of producers decreases. Hence, this will negatively affect other connected food chains in the marine food web.

In guinea pigs, the allele for short hair is dominant to long hair. A guinea pig with short hair is crossed to one that has long hair. Over a period of years, a scientist keeps records of the offspring and finds that 44 of them have short hair and 46 of them have long hair. Based on this data, what are the genotypes of the parents:
1. HH x hh
2. Hh x hh
3. HH x Hh
4. hh x hh
I would choose Option 2
about 50% chance that the dominance is in, but when it is, its dominant, of course.

When looking at the cell membrane, where are the lipid heads located?
Answer:
The cell membrane consists of two adjacent layers of phospholipids, which form a bilayer. The fatty acid tails of phospholipids face inside, away from water, whereas the phosphate heads face the outward aqueous side.
The cell membrane consists of two adjacent layers of phospholipids, which form a bilayer. The fatty acid tails of phospholipids face inside, away from water, whereas the phosphate heads face the outward aqueous side.
What is cell membrane?
The cell membrane is a biological membrane that separates and protects the interior of all cells from the outside environment.
Moreover, the cell membrane, also called the plasma membrane, is found in all cells and separates the interior of the cell from the outside environment. The cell membrane consists of a lipid bilayer that is semipermeable. The cell membrane regulates the transport of materials entering and exiting the cell.
Hence, cellular membranes — including plasma membranes and internal membranes — are made of glycerophospholipids, molecules composed of glycerol, a phosphate group, and two fatty acid chains.
