Name two possible causes of the largest mass extinction in Earth’s history and explain how this both helped and hurt different species.
Answers
Answer:
Explanation:
Two possible causes for the biggest mass extinction event in the history of our planet would be an asteroid impacting the planet and the massive volcanic activity. This mass extinction event is called the Permian-Triassic extinction. This helped many species emerge as survivors and thrive without the oppressive bigger species that died out. It hurt many species that were unable to survive the harsh conditions that resulted from everything that was happening to their habitats and food sources.

Answer:
The cheapest way for the country to make electricity would be
A) Use the agriculture biomass to generate a renewable fuel that can be burned to generate electricity
The statement provides the best reasoning for regulating the amount of fish removed from the river by humans is:
A) Regulation will help the ecosystem to remain balanced and contribute to the stabilization of other populations of river organisms.
Explanation:
For the electricity, the use of Biomass meets the demands due to the fact that, it has minimal impact on the environment, does not add carbon dioxide to the atmosphere. Also, it is renewable form of energy.
For the regulation of the amount of fish removed from the river helps to maintain the ecosystem balance. If it was not done, the fishes found in the river will be totally harvested thereby disrupting the chains in that river ecosystem.
Explain how the structures of plant tissues and organs are directly related to their roles in physiological processes.
Answers
Answer:
How the structures of plant tissues and organs are directly related to their roles in physiological processes.
o Plant organs are limited to roots, stems, leaves, flowers, fruit and cones.
o Physiological processes are limited to photosynthesis, cellular respiration,
transpiration, and reproduction.
o Plant tissues are limited to meristematic, ground, dermal and vascular tissues.
o Plant structures are limited to cambium, guard cells, phloem, seed, stomata and
xylem
Explanation: Hope this helps have a safe and happy new year
Roots, stalks, leaves, flowers, fruit, and cones are the only organs found in plants. Photosynthesis, metabolic processes, transpiration, and fertilization are the only physiological activities.
Plant and plant tissues:Photosynthesis and the movement of mineral-containing water ions are critical processes in the development of healthy plants. Plants have three primary structures or organs:
LeavesStemsRootsThey're made up of groupings of specialized tissues with structures that are tailored to the functions they do.
Adaptations are distinctive features that help plants survive in their specific settings. Plants rely on their specialized structures to provide their fundamental requirements, protect themselves from predators, and aid reproduction.

2)Drilling deep within the Earth.
3)By cutting into other terrestrial planets.
4) Our modern knowledge of the Earth's interior is just a guess that many scientists have accepted.
Answers
Answer:
I think number 1 is the answer.
Scientists gather indirect evidence using seismic waves (Earthquakes) along with what is visible at Earth's surface. The correct option is 1.
What are seismic waves?Seismic waves are caused by sudden movement of materials within the Earth, such as fault slip during an earthquake.
Seismic waves generated by earthquakes or explosions can travel through the Earth's interior, revealing information about the properties of the rocks and other materials they pass through.
In addition to seismic data, scientists use other indirect methods such as magnetic and gravitational field studies, as well as analyses of rocks and minerals found at or near the surface.
Scientists collect indirect evidence by observing seismic waves (Earthquakes) as well as what is visible on the Earth's surface.
Thus, the correct option is 1.

Bart thinks mice exposed to microwaves will get stronger (maybe he's been reading too much Radioactive Man). You decide to perform this experiment by placing 10 mice in a microwave for 10 seconds. He compared these 10 mice to 10 other mice that had not been exposed. His test consisted of a heavy block of wood that blocked the mouse's food. found that 8 out of 10 of the microwave mice were able to push the block. 7 out of 10 of the mice without microwaves were able to do the same.
identify
1. control group
2. independent variable
3. dependent variable
4. what are some of the mentioned control variables?
5. what should bart's conclusion be?
Answers
Answer:
Control group = mice that had not been exposed
Independent variable = Mice receiving radiation
Dependent variable = Number of mice that are able to push the block of wood.
Control variables = Health of mice, mass of block
Radiation does not have effect on strength of the mice
Explanation:
In an experiment the variable which changes with respect to the other variable is called the dependent variable and the other variable is called the independent variable.
The control group is the group that does not receive treatment which is used to compare the effect of the treatment.
The control variable is another variable that must be held constant when performing the experiment.
Here the
Control group = mice that had not been exposed
Independent variable = Mice receiving radiation
Dependent variable = Number of mice that are able to push the block of wood.
Control variables = Health of mice, mass of block
It was found that 8 out of 10 of the microwave mice were able to push the block. 7 out of 10 of the mice without microwaves were able to do the same. This means that there was no significant difference hence, the conclusion drawn should be that radiation does not have any effect on their strength.

Explanation:
Answer:
The respiratory system
Explanation:
The primary function of the respiratory system is to supply the blood with oxygen in order for the blood to deliver oxygen to all parts of the body. The respiratory system does this through breathing. It consists of the nose, larynx, trachea, diaphragm, bronchi, and lungs.
In humans type A blood is caused by the antigen A in the red cells resulting from gene A. Type B is caused by a gene B for antigen B. Type O blood results from the absence of either gene while the presence of both genes causes both antigens to be formed resulting in type AB blood. If a person of blood group AB marries one belonging to blood group O what will be the blood groups of their children? Show the Punnett square for this cross.

Type O blood results from the absence of either gene while the presence of both genes causes both antigens to be formed resulting in type AB blood.

A girl is born with hemophilia. Her dad also has hemophilia, but her mother does not.
What genetic explanation can you provide as to why the girl
suffers from hemophilia?
Answers
answer:
So daughters get 2 X chromosomes from the mom and dad and if the dad has hemophilia the daughter would get it too and sons would not get because they get Y chromosome from their dad and hemophilia is found in the X chromosome because the X chromosome is the one that has the instructions for making the clotting factor proteins.
Explanation:
A father who has hemophilia has the gene and passes it on to his daughter because daughters get two X chromosomes, one from their mother and the other from their father. This is why daughters of men with hemophilia are called obligate carriers. Since sons only receive a Y chromosome from their father, they would not have inherited hemophilia.
