A frog cell normally has 26 chromosomes. How many chromosomes will each daughter cell have after mitosis?
13
26
46
52
Answer:
26 chromosomes.
Explanation:
Mitosis is basically cell division. Each of the resulting daughter cells would have the same number of chromosomes at the end as the original one.
Answer:
26
Explanation:
In mitosis the daughter cell will have the same number of chromosomes as the parent cell, which is usually the diploid number. mitosis occurs for all other body cells. in this case the parent has 26 so the 2 daughter cells also have 26 chromosomes each.
in meiosis the daughter cells will have the haploid number or half the number of chromosomes than the parent cell. that means since the parent has 26 chromosomes, the 4 daughter cells will have 13 chromosomes each. meiosis occurs only for sex cells/gametes

choose the correct order of the steps in recognizing a smell. - neurons are stimulated - olfactory receptors detect vaporized odor molecules - signal forwarded to cerebral cortex for interpretation - nerve impulse travels to the olfactory bulb in the brain
The correct order of the steps in recognizing a smell is:
1. Olfactory receptors detect vaporized odor molecules
2. Neurons are stimulated
3. Nerve impulse travels to the olfactory bulb in the brain
4. Signal forwarded to the cerebral cortex for interpretation
This neural code originates from sensory neurons in the nose. When an odorant molecule binds to a receptor it initiates an electrical signal that travels from sensory neurons to the olfactory bulb. The olfactory bulb is a structure at the base of the forebrain that relays signals to other brain regions for further processing.
Olfactory receptors are located in the olfactory epithelium. This is a specialized area of the nasal mucosa that covers part of the ethmoid bone in the upper nasal cavity. The reticular formation controls the level of consciousness, the cardiovascular system, and the respiratory system. The ascending sensory system passes through the brainstem on its way to the thalamus.

Developing 150 breeds of dogs from ancestral wolves is not an example of natural selection.
The process through which populations of living things adapt and change is known as natural selection. A population's members are naturally varied, which means that they are all distinctive in some ways. This variety indicates that some people have characteristics that are more environment-appropriate than others. People that possess advantageous qualities, or adapted traits, are more likely to live and procreate. The adaptable qualities are subsequently passed on to the next generation by these people. These beneficial characteristics spread across the population over time. Favorable features are passed down across generations as a result of natural selection. Natural selection may result in speciation, the process by which one species gives rise to another that is utterly separate.
Hence, survival of the fittest species take among population.

while admiring the fossils at the arizona museum of natural history you recall the various species concepts you learned about in this class. of the four species concepts listed below, which one could you not apply to the fossils to assess speciation? group of answer choices phenetic species concept phylogenetic species concept biological species concept evolutionary species concept next
To assess speciation, the biological species concept cannot be applied to fossils.
A species, based on the biological species concept, is a group of organisms that can effectively interbreed and produce fertile offspring. This theory holds that both interbreeding within a species and reproductive barriers between organisms of different species help to protect a species' integrity. Most evolutionary biologists agree with the concept.
This same biological species concept is not applicable to fossil species so because flow of genetic data as well as reproductive behaviour cannot be studied using fossil remains. It is limited to living things that exhibit the interbreeding pattern. The phylogenetic species idea can be used to investigate fossil species.
Asexual reproduction does not involve interbreeding, and any evolution observed in organisms is the result of mutations. As a result, the concept of biological species does not apply to asexual organisms.
Allopatric speciation describes biological populations which are geographically separated and thus unable to interbreed. The concept of biological species is irrelevant to allopatric speciation.

Territories are typically used for activities such as
A) feeding, mating, and rearing young.
B) migration and feeding.
C) identification of kin and rearing young.
D) feeding and identification of kin.
Territories are typically used for activities such as : feeding, mating, and rearing young.
A 'territory' is any defended area, and often these birds are territorial (mostly in the context that they safeguard some area, even if it is just a nest spot) for at least part of the year. The upside or advantage of protecting a territory is that the 'owner' has access to an asset or more of a resource (or access to an improved quality resource) than they otherwise would have.
Territories can be classified according to the resource (or resources) being defended:
Type A territory, or mating, nesting, and feeding territory is a zone in which all activities take place (such as courtship, mating, nesting, & foraging). It also known as a "all-purpose territory", the kind of territory that many songbirds defend
Type B, also known as mating and nesting territory. All breeding activities take place here, but most foraging takes place elsewhere. This type of territory is the one that male Red-winged Blackbirds defend

calculate the probability that Louise and
Robert will have two girls and two boys in any
order. (Hint: set up a table to help you
determine all the different combinations
possible.)
ans is even chance means 50/50
Explanation:
they have 50/50 chance
The required probability is 0.0625 or 6.25% that Louise and Robert will have two girls and two boys in any order.
What is probability?Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.
The probability of having a girl or a boy is 0.5 (assuming the chance of having either is equal).
To determine the probability of having two girls and two boys in any order, we can use the multiplication rule of probability.
In this case, we can break the problem down into 4 independent events:
The probability of the first child being a girl
The probability of the second child being a girl
The probability of the third child being a boy
The probability of the fourth child being a boy
Each event has a probability of 0.5, so we can multiply these probabilities together to find the overall probability:
(0.5) × (0.5) × (0.5) × (0.5) = 0.0625
So the probability that Louise and Robert will have two girls and two boys in any order is 0.0625 or 6.25%.
