Examples of how humans negatively affect local ecosystems are
A. Building dams, deforestation cutting down trees), adding point sources to nearby streams to allow for run-off, building roads and structures, and salting roads
B. Planting trees and other plants to attract native species
C. Creating laws to prohibit fishing from local streams
D. Removing non-native species from the environment.
Answer:
A. Building dams, deforestation cutting down trees), adding point sources to nearby streams to allow for run-off, building roads and structures, and salting roads.
Explanation:
Removing non-native species from the environment helps the native ants to thrive without having any changes in the ecosystem effect them (i.e. new invasive animal).
Creating laws to prohibit fishing from local streams helps keep the fish alive and allowing them to continue to use this stream.
Planting trees and other plants to attract native species helps secure and grow the ecosystem of that area.
This leaves A as the answer.
Hope that helps you!

The rate at which blood flows through the human body can change in response to multiple factors. Which statement describes one of these factors and the effect it has on blood flow?
A. The narrowing of blood vessels increases pressure and leads to faster blood flow
B. High blood viscosity increases the resistance in the blood vessels and leads to faster blood flow.
C. Low blood pH decreases the rate of diffusion through the blood vessels and leads to slower blood flow.
D. The changing of the shape of red blood cells to a crescent shape decreases resistance and leads to faster blood flow.
Explain why this is the correct answer and why the other ones are wrong:
Answer:
B
viscosity of blood causes an increased resistance in the blood vessels and
leads to slow blood flow
Explanation:
Viscosity refers to the thickness of blood. This thickness is caused by the number of red
blood cells. Thick blood travels through blood vessels at a slower rate than thin blood

Which of the following are parts of a bacterial cell?
Select all that apply.
mitochondria
flagella
cell wall
pili
Answer:
It is a gel-like matrix composed of water, enzymes, nutrients, wastes, and gases and contains cell structures such as ribosomes, a chromosome, and plasmids. The cell envelope encases the cytoplasm and all its components. Unlike the eukaryotic (true) cells, bacteria do not have a membrane enclosed nucleus.
Explanation:
Flagella, cell wall, and pili are parts of a bacterial cell.
What is a bacterial cell?Microscopically small, single-celled creatures known as bacteria are found in millions in every habitat, both within and outside of other living things.
Some bacteria are hazardous, but most serve a helpful role. They are employed in industrial and medical procedures and sustain a wide variety of living forms, including both plant and animal life.
Around 4 billion years ago, bacteria are assumed to be the initial lifeforms to emerge on the planet. The earliest fossilized creatures are bacteria-like ones. Most biological and some materials can be used as food by bacteria, and certain strains can withstand harsh environments.
New insights into the functions of the gut microbiome are being provided by this expanding interest in how microorganisms affect human health. Bacteria are prokaryotes that do not contain any membrane-bound organelles.
Therefore, flagella, cell wall, and pili are parts of the bacterial cell.

What structure is found in viruses but not in cells
Answer:
Acellular
Explanation:
Viruses are acellular, meaning they are biological entities that do not have a cellular structure. Therefore, they lack most of the components of cells, such as organelles, ribosomes, and the plasma membrane.
You cross nonpure tall plants (Tt) and produce 200
offspring. Which of the following statements about
the offspring is correct?
A. All of the offspring will definitely be tall.
B. 150 of the offspring will definitely be tall.
C. There is a 75% chance that each offspring
will be tall.
O D. There is a 25% chance that each offspring
will be tall.
Answer:
C is the best answer
Explanation:
the dominate trait is in 3 of the four boxes
There is a 75% chance that each offspring will be tall. Therefore option C is correct.
When you cross non-pure tall plants (Tt), you are dealing with a heterozygous genotype, meaning the plants have one dominant (T) and one recessive (t) allele for the height trait.
The dominant allele (T) is responsible for the tall phenotype, while the recessive allele (t) leads to short plants. In this case, 75% of the offspring will likely receive the dominant allele from at least one parent (Tt or TT) and therefore be tall.
The remaining 25% will inherit the recessive allele from both parents (tt) and be short. This is based on the principles of Mendelian genetics and the Punnett square.
Therefore option C There is a 75% chance that each offspring will be tall is correct.

WILL GIVE BRAINLIST!!!!! what are 3 ways that animals and plants can erode rocks in different locations?
Answer:
Hope this Helped :)
Explanation:
1.Biological weathering-Plants and animals release acid forming chemicals that cause weathering and also contribute to the breaking down of rocks and landforms.
2.Plants change Earth’s surface through weathering and erosion.They take minerals from the rock. This is a type of weathering, and it weakens the rock. Eventually the surface of the rock starts to break down and become soil.
3.As larger plants like trees start to grow in a rocky area, their roots
grow into the small cracks in the rock. Slowly, as the tree grows, its roots break the rock apart. This forms more soil and makes it easier for other plants to grow there as well.
4.When too many animals live in one place, they tend to eat and trample all the plants. Without the plants to protect the soil, it is more likely to be eroded by wind and water.

ANNOTATE Write the inputs and outputs of cellular respiration on this diagram.
Answer:
Inputs---- glucose and oxygen.
Outputs----- ATP, carbondioxide and water.
Explanation:
The inputs of cellular respiration are the glucose and oxygen whereas the outputs of cellular respiration are energy in the form of ATP, carbondioxide gas and water. cellular respiration is a process in which glucose is broken down in the presence of oxygen gas for the production of energy in the form of ATP molecules. Carbondioxide gas and water which are the waste materials also produced in the end of cellular respiration process. Cellular respiration is the reverse of photosynthesis.
