Three functions of the eye help!!!!!
Explanation:
The eye receives oxygen through the aqueous. Its function is to nourish the cornea, iris, and lens by carrying nutrients, it removes waste products excreted from the lens, and maintain intraocular pressure and thus maintains the shape of the eye. This gives the eye its shape. It must be clear to function properly.
Answer:
These layers lie flat against each other and form the eyeball.
The outer layer of the eyeball is a tough, white, opaque membrane called the sclera (the white of the eye). ...

You are part of a small group of humans rocketed at “warp speed” to Planet X, without any books, weapons, or technology. Planet X has no ozone layer to protect its surface from cancer-causing ultraviolet radiation, but native plants and animals have evolved to live safely there. Below the surface, the planet has a network of underground tunnels, just a meter high, which are inhabited by carnivorous predators.
Write 3 paragraphs using the vocabulary words we discussed today in class about how descendants of the group of humans would look and act after evolving for 100,000 years on Planet X.
Use these vocabulary words:
• Evolution
• Mutation
• Non-random Mating
• Gene Flow
• Genetic Drift

13. Populations of organisms grow at an _______ rate, but ____ factors such as food, habitat, predators, weather, disease, climate, & temperature can affect the maximum population size an area can support.
14. Sea otters are an example of a _________ species where the effects of overhunting this population of organisms will severely affect the population #s of other species.
15. _______ is determined by the # of species in a specific area as well as the # of different kinds of species in a specific area.
1. What controls how the anatomical structures of an organism develop?
The following are all concepts of natural selection EXCEPT: *
1. Variations can be inherited.
2. A limited number of individuals born will survive to adulthood.
3. There is a struggle for existence among offspring of the same species.
4. All organisms of a species will survive.
Answer:
2 A limited number of individuals born will survive to adulthood.
Explanation:
Answer:
4. All organisms of a species will survive
Explanation:
4 is the complete opposite of natural selection.
Natural selection basically says that certain members of the species will die off and the more fit ones will survive and produce stronger, better-adapted offspring.
what cause's cell division
Cells divide for many reasons. For example, when you skin your knee, cells divide to replace old, dead, or damaged cells. ... When organisms grow, it isn't because cells are getting larger. Organisms grow because cells are dividing to produce more and more cells
The accidental introduction of invasive species of plants and animals often
causes severe problems in the ecosystem where they are introduced. One such
example is in Texas. The Rasberry crazy ant (Nylanderia pubens) which is thought
to have arrived in 2002 from South America. This ant species is known to attack
livestock, displace existing species, and damage electrical equipment. N pubens
consumes "honeydew," a sugary liquid substance secreted as a waste product by
aphids, which suck the sap out of plants.
Which of the following statements best explains the impact that N. pubens has
on its environment?
Answer: N. pubens has found a place within the existing food web in its new environment.
Explanation:
The statement that best explains the impact that N. pubens has on its environment is that "N. pubens has found a place within the existing food web in its new environment".
From the information given, it's stated that the Rasberry crazy ant (Nylanderia pubens) was accidentally introduced in Texas and it attacks livestock, displace existing species, and damage electrical equipment.
It's further stated that it consumes "honeydew," a sugary liquid substance secreted as a waste product by aphids, which suck the sap out of plants.
This shows that it has found a place within the existing food web in its new environment.
¿Qué impacto tendría que los microorganismos en el ciclo del carbono y nitrógeno no cumplieran en su función?
Answer:
Ver explicación
Explanation:
Los microorganismos son muy importantes en el ciclo del carbono porque descomponen la materia orgánica. Esta descomposición de la materia orgánica se llama descomposición. Este proceso devuelve carbono al suelo. Si estos organismos no desempeñan su papel, el ciclo del carbono estará incompleto porque el carbono no se devuelve al suelo como materia orgánica.
En el ciclo del nitrógeno, las bacterias nitrificantes atrapan y fijan el nitrógeno atmosférico en el suelo, mientras que las bacterias desnitrificantes convierten los nitratos del suelo en nitrógeno. Las actividades de estos microorganismos mantienen el equilibrio del hidrógeno en el ciclo del nitrógeno.
As you worked down the dichotomous classification key to identify sharks, did you go from general to specific characteristics or from specific to general characteristics? Explain your answer using four characteristics that were used in the shark key.
When constructing a dichotomous key, we should start with general characteristics and then move to more specific characteristics. A dichotomous key lists an organism's structure and behavior so it may be recognized through elimination.
What are four characteristics that are used in the shark key?When attempting to categorize an organism, scientists frequently make use of a dichotomous key. A dichotomous key is a listing of specific features, such as structure and behavior, in such a way that an organism may be identified through a process of elimination. Examples of dichotomous keys include the following:
The shape of the body, the number of gill slits, the position of the mouth, and the shape of the caudal fins are the dichotomous keys for identifying sharks. Other features include the length of the dorsal fins or the number of dorsal fins, the presence or absence of pelvic fins and the shape of the skull.

What conclusion can you make regarding how humans affect biodiversity? Is evidence from the graph to support your answer
Answer:
Decrease population of staghorn coral and spotlight parrot fish.
Explanation:
Humans greatly affects biodiversity by decreasing the population of most of the organisms due to its activities. Human activities causes pollution in the environment as well as disturbed the habitats of many organisms that leads to decrease in their population. Humans activities releases carbondioxide gas in large concentration that will leads to the increase of pH of the ocean water which adversely affected the population of many marine animals such as staghorn coral and spotlight parrot fish etc so that's why we can say that human activities adversely affected biodiversity.
In your own words, give a brief overview of the process of photosynthesis. Include where each phase place within a plant cell.
Answer:
Photosynthesis has two parts: the light-dependent reactions and the dark reactions (the Calvin cycle). Photosynthesis in a general sense, uses CO2 and water to create C6H12O6 (glucose) and oxygen. The light-dependent reactions use water to make oxygen, and a reduced energy carrier (NADPH) is also created. The Calvin cycle uses carbon dioxide and ATP to create G3P for glucose.
The light-dependent reactions occur on the membrane of the thylakoid and also involve shuttling electrons across different complexes (photosystem II and photosystem I), eventually causing ATP to be created with a proton gradient.
The light-independent reactions/Calvin cycle occur in the stroma of the chloroplast and also involve shuffling carbons around. Carbon dioxide is processed in three stages, and glucose is made from 6 CO2.

Why are nonnative species a threat to biodiversity?
They often use up resources that other organisms need.
They are not able to successfully breed in the wild
They release pollution into many environments. l
They easily contract and spread diseases to other organisms.
Answer:
The non-native species are the prime threat to the surroundings as they can modify habitats and change the ecosystem services and function, and may replace or crowd-out the local species. The non-native species are considered as the second-ranked major threat to biodiversity after habitat destruction like deforestation.
Answer:
If you're only allowed to have one answer: They often use up resources that other organisms need.
If you can have multiple, then :
They often use up resources that other organisms need.
