The scientists have continued to study a new area in South Africa, and they want to predict how many wild dogs could occupy this area. Here are some facts about the new area. In the new area:The wild dogs will feed on Impala and Kudu. The growth rate of the impala and kudu is similar to the rate in Northeastern SA and Northern SAThe prey density is twice as high as in Northern SA (30 Impala / km2 and 8 Kudu per km2)The average rainfall is between 400 and 650The amount of available prey biomass is similar to Northeastern SAHow many wild dogs could this area support?2412366
Answers
We have the data of the known areas
The new area is similar to Northeastern SA and Northen SA in terms of the type of prey and the growth rate, as well as rainfall.
And even if the density is greater, the total biomass is similar to Northeastern SA, so the population that the new area can support must be similar to the one in there.
Northeastern SA has an area of 1000 km2, so, according to the next graph, it can sustain at least 29 individuals. This means the new area should be able to support around that same quantity.
Given the information and from the options, the answer would likely be 36.

Variable-ration schedules is reinforcement schedule where appropriate movements are reinforced after a varying number of responses.
Partial reinforcement schedules is defined as either fixed or variable, and as either interval or ratio. Combinations of these four rubric produces four kinds of partial reinforcement schedules these are fixed-ratio, fixed-interval, variable-ratio and variable-interval.

You compare two strands of mtDNA and discover that there are 3 differences in base pairs between them. Assuming that the mutation rate for the species that you are examining is 1 mutation every 20,000 years, how long ago did the two strands share a common ancestor? Write your answer in xxx,xxx format.
These two strands shared a common ancestor _____________ years ago.
pls need the help
Answers
The two strands of the DNA share a common ancestor before 60,000 years ago.
Given here that the mutation rate is 1 in every 20,000 years. So it takes 20000 years to take single mutation.
Thus , the third mutation can occur 3×20000 years = 60,000years.
A mutation is a change to an organism’s DNA sequence. Errors in DNA replication during cell division, exposure to mutagens, or viral infection can all cause mutations. Our cells are constantly undergoing mutations, yet very few of these have any negative effects on our health.
There are numerous explanations for why mutations typically don’t have significant effects. The majority of mutations occur in somatic cells, such as muscle or skin cells, and only have an impact on the cell in which they originate and cells that develop from that cell.

Answers
An organism responds to external stimuli because of sensitivity.
Why do organisms respond to external stimuli?External stimuli are the number of factors present outside of the body that absorb by receptors and will lead to a response. External stimuli are temperature changes, vision, hearing, tasting, smelling, and sunlight for plants. Organisms respond to external stimuli to maintain homeostasis. Each organism has its range of sufferance. When an environmental condition (such as temperature) goes above or below an organism's optimal range, the organism experiences stress and responds to the stimulus. For example, external stimuli Plants grow towards light(external stimuli) sources, and if the direction of light is changed, the plant will also change its direction of growth to accommodate for survival.

Ice cubs is faster heating in a stove than the microwave .Ice cubes melt almost immediately when heated directly.The ice cubes will instantly melt if you put them adjacent to lighted matches, use a hot stove, or use a lighter.
Why does ice cubes melt?
The velocity of the water molecules in the ice increases as energy is delivered to them.The ice melts as a result of the molecules' increased velocity, which is strong enough to resist the pull of the water molecules toward one another. Ice does melt in the microwave, but not as quickly as one might anticipate from a device that can quickly prepare meals.The majority of people do not believe that ice will melt in a microwave, The water molecules turn to line up with the microwaves' alternating electric field.The water heats up as they fast spin back and forth.The water molecules are fixed in place by the ice.They cannot rotate back and forth, therefore the microwaves cannot be converted into heat. according to magician and science enthusiast Jason Latimer.Before microwaving, place the ice cube and cover on top to generate steam that will allow the food to reheat completely.By adding the ice cube to the bowl, you give the microwave something to heat, and the steam is then distributed throughout the food, preventing leftovers from remaining cold.The water heats up as they fast spin back and forth.The water molecules are fixed in place by the ice.They cannot rotate back and forth, therefore the microwaves cannot be converted into heat. Ice is a solid form of water.The ice transforms into liquid water when heat (a type of energy) is introduced.0°C, the melting point, has been attained.Water will become water vapour, or water in its gaseous condition, if heat is applied indefinitely. You might assume intuitively that hot water always melts ice more quickly than cooler water, but this isn't always the case.See what happens if you drop a few ice cubes into warm water and then submerge a few more in frigid water.Warning: the cold tap will cause the ice to melt more quicklyThe water will begin to boil where it contacts the hot pan while it sits there.The best way to demonstrate it is to heat the skillet up till water touches it begins to boil.In reality, the steam will cause the ice to float just millimeters over the pan's bottom.

Answers
The statement DNA polymerases cannot initiate synthesis of a new DNA strand; they can only add bases to an existing strand is TRUE about DNA replication while the mismatch repair mechanism is initiated by strand-specific nicks.
What are DNA polymerases?DNA polymerases are specific enzymes that add nucleotides during the semiconservative replication of DNA, which involves the synthesis of a new DNA strand for each daughter DNA molecule.
Moreover, the mismatch repair mechanism refers to the pairing between nucleotide sequences other in DNA and double stranded RNA (dsRNA) is initiated by strand-specific nicks in order to repair a given nucleotide sequence.
Therefore, with this data, we can see that DNA polymerases are essential enzymes used by the cell in order to synthesize a DNA strand during the process of semi-conservative DNA replication, which occurs before the process of cell division and may involve mismatch repair mechanisms.

A. Succession
B. Natural Selection
C. Gene Flow
Answers
Answer:
Its The Gene Flow
Explanation:
Gene flow refers to the transfer of genetic material, specifically alleles, from one population to another through the movement of individuals. The correct option is C.
Gene flow occurs when individuals migrate or move between different populations, bringing their genetic variation with them.
When individuals migrate into a population, they introduce new alleles, potentially increasing the genetic diversity of the population.
When individuals emigrate from a population, they take their alleles with them, resulting in a loss of genetic diversity in the population they leave behind.
It can introduce new alleles that may provide adaptive advantages, enhance genetic variation, or counteract the effects of genetic drift.
It also has the potential to spread beneficial alleles throughout populations, improving their adaptive potential.

What is carbon backbone?Carbon skeleton is also known as carbon backbone. All organic compounds are made up of carbon-carbon bonds, which form a carbon skeleton or backbone. The carbon atom has special effects that allow it to form covalent bonds with up to four additional atoms, making it excellent for use as the basic structural component, or "backbone," of macromolecules. This carbon backbone is made up of chains and/or rings of carbon atoms with the addition of an element such as nitrogen or oxygen on occasion. Substituted hydrocarbons are molecules with other elements in their carbon backbone. The term carbon skeleton refers to the pattern in which carbon atoms are bonded together in a molecule, ignoring other atoms and differences between single and multiple bonds.
