When can a solar eclipse occur
Answer: when their is a new moon
Explanation:
Total solar eclipses happen when the Moon completely covers the Sun, and it can only take place when the Moon is near perigee, the point of the Moon's orbit closest to Earth. You can only see a total solar eclipse if you're in the path where the Moon casts its darkest shadow, the umbra.
Scientists have proposed more than two dozen ways to define species. One commonly used definition, called the biological species concept, holds that populations belong to the same species if they can contribute genes to a common gene pool. Reproductive barriers block gene flow between different species. Gene flow between populations tends to hold the gene pool of a species together.

Complete question:
Scientists have proposed more than two dozen ways to define species. One commonly used definition, called the biological species concept, holds that populations belong to the same species if they can contribute genes to a common gene pool. Reproductive barriers block gene flow between different species. Gene flow between populations tends to hold the gene pool of a species together.
Part A - Comparing species definitions
Three of the most prominent definitions of species are the biological species concept, the phylogenetic species concept, and the morphological species (morphospecies) concept.
Drag each characteristic to the appropriate bin based on the species concept(s) to which it applies → You will find this in the attached files
Answer:
Not applicable for extinct species → Biological Based on evolutionary history → Phylogenetic Relies on similarities in structure → Morphological Accommodates asexual reproduction / Species acceptance criteria can be subjective → Morphological and PhylogeneticUsed by scientists in classification → Morphological, Phylogenetic, and BiologicalExplanation:
The biological concept states that species are population groups that -in a real or potential way- can mate and reproduce, but are reproductively isolated from other groups.
Individuals belonging to a species cannot reproduce with members of other species.
This biological concept has limitations. Its application might present difficulties in concern with asexual reproduction species, such as bacteria, rotifer, cnidarians, plants, and etcetera.
Besides, this concept cannot be applied to the past because it is difficult to deduce reproductive capability between extinct species.
Finally, this concept is not adequate concerning hybridization zones, something to be expected considering evolutionary processes. This is the reason why it has been less accepted by botanists, as some plant species hybridize with other species.
The phylogenetic species concept defines species on a determined time and through time, and these are the horizontal and vertical species concepts, respectively. The species group is considered to be the less inclusive monophyletic group.
According to the phylogenetic concept, a species is a monophyletic group whose organisms share synapomorphies.
The establishment of species relies on molecular markers.
The morphological species concept defines species according to the shared morphological characteristics shared by all the members of the species. It is a descriptive method to separate species.
When a group differs considerably at a morphological level from another group, it is defined as a different species.
Some limitations might emerge from this species concept. It does not consider variability among individuals,
Individuals of the same species might be polymorphic, exhibiting morphological differences between organisms. These individuals would be considered to be different species following the morphological concept. Some different species might be morphologically similar, despite being different. These species might be considered as one following the morphological concept.What did Gregor Mendel use to discover the principles that rule heredity?

Answer:
This looks like an earthquake
Explanation:
There doesn’t seem to be very much water present in the image which would be the cause for the rest of them
Hope this helps
Answer:
Earthquake
Explanation:
First off I wouldn't say landslide because if it was a landslide in more than likely would have cracked the concrete on the floor that the people are standing on and there would be more of a mess than what is show in the picture. Next I wouldn't say tsunami depending on how frequent this disaster was, if it was a tsunami more than likely most of that rubbish would have been soaked with water in other things that were in the water as well and I wouldn't say flood either because once again nothing is soaked with water with in that picture not even the concrete that the people are standing on so I say that the most reasonable answer would be earthquake due to them being know for destroying buildings alot.

Explanation:
what organisms are being affected by pollution how or why/why not?
Answer:
Most marine animals
Explanation:
Most of your plastic trash ends up in the ocean. It is dumped by companies who don't know what to do with it. Seabirds are constantly eating the tiniest of plastics called microplastics, which fill the birds stomach. The bird does not feel hungry, so it doesnt eat and starves to death. Sea turtles are constantly choking on plastic, because when it floats in the water, it looks like their food: jellyfish. Sea otters pelts are unable to be waterproofed due to oils in the water, which neutralizes the waterproof oils in their fur. Not just in the ocean. CO2 emissions increase the amount of CO2 that stays in the atmosphere, which dissolves in the ocean and increases its acidity. This does a variety of things, to killing coral reefs, deforming shellfish, and outright poisoning fish. Increased CO2 builds up the greenhouse gasses around the planet, and increases the heat that bounce back to earth, thus warming the planet. This results in melting the ice of the north pole, where methane gas is trapped in the ice, thus releasing that methane to the atmosphere, and increasing ocean acidification.

How can bacteria survive vaccines?
Answer.
Toxoids are chemically inactivated toxins from bacteria like Clostridium tetani or Corynebacterium diphtheria. The infection with these bacteria itself does not cause the illness, but rather the exotoxins released from the bacteria. Accordingly, vaccination with toxoids leads to an antibody production against the toxins that neutralize the proper toxin protecting the body against a range of important diseases (Marvaud et al., 1998; Collier, 1975).

In your own words explain how you think that DNA, mutation, genotype, phenotype, and natural selection interconnect to cause evolution
Answer: According to sources, the most probable answer to this query is that evolution happens because when life came it sought for survival. Now, this is through mutation which causes random DNA sequences leading to genotypic and phenotypic changes. Natural selection as relation to adapting to the selection forces of the environment. And when these factors is added by the niche and other large case scenario to cause major anatomical changes, speciation comes through. And that, the process of evolution. And how it is a mechanism and an intermediate interaction with the environment.
Explanation:
The mechanism that establishes the medullary osmotic gradient depends most on the permeability properties of the ________. The mechanism that establishes the medullary osmotic gradient depends most on the permeability properties of the ________. distal convoluted tubule nephron loop glomerular filtration membrane collecting duct
Answer:
The correct answer is nephron loop. The mechanism that establishes the medullary osmotic gradient depends most on the permeability properties of the nephron loop.
Explanation:
The nephron loop is the portion of the nephron that follows the proximal convoluted tubule. It is located mainly in the renal medulla. Water moves by osmosis thanks to an osmotic gradient, in other words, it moves from a space with a lower concentration of solutes (hypotonic solution) to a space with a higher concentration of solutes (hypertonic solution) to try to dissolve it. Among the functions of the nephron loop is the creation of the medullary osmotic gradient by the countercurrent multiplier mechanism. Osmolarity is an intensive property that requires one or more "sources" of osmoles, capable of creating a gradient. In the nephron loop there are several sources of this type: a) the system that transports NaCl in the thick portion of the ascending limb b) the passive Na + outflow from the thin portion of the ascending limb c) the Na + outflow and of urea from the collector.

________ thousands of tiny projections that add even more surface area to villi
Answer:
Each villus, in turn, has thousands of even smaller projections called microvilli (singular: microvillus).
Explanation:
The villi contain capillaries, which are tiny blood vessels. Nutrients are absorbed into these capillaries across the surfaces of the villi and microvilli. Because there are millions of these tiny projections, they greatly increase the surface area for absorption.

For example, plasma membrane proteins carry out functions as diverse as ferrying nutrients across the plasma membrane, receiving chemical signals from outside the cell, translating chemical signals into intracellular action, and sometimes anchoring the cell in a particular location.
Answer:
All cells have plasma membranes. Can molecules enter and leave the cell? Yes. The plasma membrane (also called the cell membrane), is a lipid barrier where molecule organelles live. The golgi ( a cell organelle) helps move the proteins across the plasma membarane. Proteins cannot move through the plasma membrane barrier by themselves because they are not small enough like water.
