Answer:
Blue Crabs can last up to 24 hours out of the water as long as they are kept cool and moist.
Explanation:
Answer:
Long as their gills are kept moist
Explanation:
However, unlike fish, blue crabs can survive out of water for long periods of time-even over 24 hours-as long as their gills are kept moist. When out of water, crabs will seek out dark, cool, moist places to help prevent their gills from drying out and to hide from predators.
There are three sources of genetic variation in sexual reproduction. Determine which of the following statements accurately describes which of these are considered random and which are not
Genetic recombination and independent assortment are considered random sources of genetic variation, while mutations can occur randomly or due to specific factors.
In sexual reproduction, the three sources of genetic variation are genetic recombination, independent assortment, and random mutations. Among these sources, genetic recombination and independent assortment are considered random processes, while mutations are not entirely random.Genetic recombination occurs during meiosis when homologous chromosomes exchange genetic material through crossing over. This process is considered random as the precise locations where recombination events occur are unpredictable.Independent assortment refers to the random alignment and separation of homologous chromosomes during meiosis I. The random positioning of maternal and paternal chromosomes contributes to genetic diversity in offspring.On the other hand, mutations are not entirely random as they can be influenced by various factors such as exposure to mutagens or errors in DNA replication. However, the specific mutations that occur at particular loci are generally considered random events.Therefore, the accurate statement would be that genetic recombination and independent assortment are considered random sources of genetic variation, while mutations are influenced by both random and non-random factors.For more such questions on Genetic variation:

the membrane depolarizes.
When X fires 10 times and Y fires 10 times, the result will be a subthreshold summation.
Subthreshold summation happens when two or more presynaptic inputs that are sub-threshold (i.e., they cannot create an action potential) combine their effects on the postsynaptic neuron.
Here, the postsynaptic neuron has an RMP of -70mV and a typical threshold of -55mV. When neuron X is stimulated, it depolarizes by 0.5 mV.
When X and Y are stimulated simultaneously, the postsynaptic neuron depolarizes by 1 mV, which is sub-threshold (below -55mV).
Therefore, when X fires 10 times and Y fires 10 times, the postsynaptic neuron will experience subthreshold summation and no action potential will be fired.

Analyze the graphs below. Which growth model would apply to a population of squirrels arriving on a new island? Assume the squirrels have no way to leave.
A logistic growth model is most appropriate for expanding squirrel populations to new islands.
Give a brief account on logistic growth model.A logistic growth model is one that incorporates carrying capacity to show how growth slows when a population reaches a point where the amount of resources is limited. As the population grows, the organism's population reaches the carrying capacity and stays there. This is the maximum population the environment can support.
Population grows more slowly as it approaches carrying capacity (K), or the maximum population that the surrounding area can support according to the population logistic model. According to this declaration, all members of the population have equal access to resources and chances of survival.

what are some basic things about genetics and how they function (need for a one pager)
People receive their parents' chromosomes, which house their genes. The 23 pairs of the 46 chromosomes that make up the human genome total 46. Chromosomes are paired. One set of each pair of chromosomes—one from the mother and one from the father—is randomly inherited by a child from each parent.
Genes serve a variety of purposes.
As parts of genetic material, genes are also units of inheritance.
They regulate the phenotypes or morphologies of individuals.
Cell division requires the replication of genes.
Hereditary information is passed down from one generation to the next through genes.
Here are five genetics-related facts.Genetics: Interesting Facts
About 90% of the genetic material in mice and 98% in chimpanzees is shared by humans. A nearly complete copy of the human genome is found in every cell of the body. Both our mother and father contribute 23 chromosomes to us. Genes can be passed down to cause some diseases.

Evolutionary trees (phylogenies) represent a succession of related species, with the most recent at the tips of the branches. Each branch point represents a common ancestor of all species that radiate from it.True or False
This assertion is accurate.
The majority of contemporary classification schemes, or phylogenies, are based on the evolutionary connections between organisms. Phylogenetic classification methods arrange species or other groups in ways that correspond to how we understand how they descended from a common ancestor. The species or groups of interest are located at the ends of lines known as the tree's branches in a phylogenetic tree. We depict our best theory about how a group of species (or other groups) emerged from a common ancestor when we create a phylogenetic tree. This theory is based on data we've gathered about our set of species, including things like their physical characteristics and the amount of time they spend growing. Every branch point contains the most recent common ancestor of all the groups that have descended from that branch point.

What are evolutionary relationships?
Systematics, taxonomy, phylogenetics, and evolution are the four approaches used to investigate evolutionary connections. The branch of science known as systematics is concerned with classifying species and figuring out their relationships. It has two primary branches that may be separated:
Organisms are classified, given names, and grouped in taxonomy. A population, species, genus, or higher-level grouping like a family, order, class, phylum, kingdom, or domain can all be considered as a group or taxon. The word taxon is pluralized as taxa. The determination of evolutionary links or patterns of descent of species is via the study of phylogenetics.
The species of living things that exist now are all descendants of earlier ones. This is the result of evolution or merely time-related change. Branching evolutionary trees can be used to illustrate the evolutionary links between ancestors and their offspring. An evolutionary tree shows which ancestors gave rise to which descendants, much like your family tree does.
Therefore the correct option is B.

Answer:
Here's an explanation instead:
Explanation:
ALL STARS BEGIN IN A STELLAR NEBULA / NEBULA
Depending on how much mass the star has, it changes what path of life cycle it will take. Low mass or average mass stars become an average star, also called a main sequence star. It swells after millions of years into a Red Giant which is GIANT. Many many many years later, it becomes a planetary nebula, and finally becomes into a white dwarf.
If the star has a large mass, it is classified as a massive star, and also goes through a form of main sequence. It swells into a MASSIVE GIANT TREMENDIOUSLY LARGE AND UNNECCESSARILY BIGGO star called Red Supergiants. After millions and billions of years, it becomes a Supernova, which finally becomes a black hole if the outer layers literally get blown off into space and the core collapses and gets compacted into incredibly dense Nano-Googleplex sized molecules. If it doesn't, it becomes a cool Neutron Star.
