Thanks Hope it helps.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.
What are 2 pieces of evidence that help approximate the age of earth?
How do those piece of evidence help scientists?
Help please this is do Tonight!!!
I will make brainlist!!
Answer: 1. By dating the rocks in Earth's ever-changing crust, as well as the rocks in Earth's neighbors, such as the moon and visiting meteorites, scientists have calculated that Earth is 4.54 billion years old, with an error range of 50 million years. Related: How Big is Earth? 2. Scientific evidence relies on data, and it is crucial for researchers to ensure that the data they collect is representative of the “true” situation. This means using proved or appropriate ways of collecting and analysing the data and ensuring the research is conducted ethically and safely. Fossil evidence shows the changes in lineages over millions of years, such as in hominids and horses. Studying anatomy allows scientists to identify homologous structures across diverse groups of related organisms, such as leg bones. Vestigial structures also offer clues to common ancestors.
Explanation:
Answer: There are many different ways we can determine the earth's age. 2 pieces evidences that help apporximate the age of the earth is the dating of the rocks and fossils. Also dating the rocks in Earth's neighbors, like the moon and visiting meteorites.
Scientists have calculated that Earth is 4.54 billion years old, with an error range of 50 million years
Explanation: if you look and date the rocks in the earth's crust and the moon and meteorites that could give us a date of how old the earth is becuase the rocks and fossils have been here for a long time.

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.

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). ...
The middle layer is the choroid. ...
The inner layer is the retina, which lines the back two-thirds of the eyeball.

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.
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.

Which day had the highest relative humidity ?
Explain why bacteria are essential parts of the nitrogen cycle.
Answer:
The most important part of the cycle is bacteria. Bacteria help the nitrogen change between states so it can be used. When nitrogen is absorbed by the soil, different bacteria help it to change states so it can be absorbed by plants. Animals then get their nitrogen from the plants.
Explanation:
Hope this helps
Answer:
Bacteria are a very important part of the nitrogen cycle because it helps to change or fix nitrogen into a usable form. Interesting Nitrogen Cycle Facts: Plants absorb nitrogen directly from the soil.

Explanation:
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.
The mitochondria are organelles that convert food into ATP, energy your cells can use. The text describes the mitochondrion as an organelle with two membranes, an outer and inner. Using evidence from the text, describe the inner membrane and how it is able to increase its ATP production due to this membrane.
Answer:
Causes oxidative phosphorylation.
Explanation:
The mitochondrial inner membrane is the site of the electron transport chain which is an important step in aerobic respiration because the inner mitochondrial membrane converts energy through oxidative phosphorylation which is the main process that is responsible for the production of energy in the form of ATP. There is inter-membrane space between the inner membrane and outer membrane where ATP synthase, an enzyme embedded in the inner mitochondrial membrane that is responsible for high ATP production.
