During the Muscle Fatigue Lab, how did you get lactic acid buildup in the muscles?
Answer:
Anaerobic Respiration
Explanation:
As you exercise your muscles needs more energy. Due to lack of oxygen in your body your body performs anaerobic rresporation the waste product produces by anaerobic respiration is lactic acid.I need help I will mark brainliest
Can someone give me the step by step answer
Answer
68.6 m
Explanation:
Given-
Mass = 0.5 kgPotential energy = 34.3 JTo find -
Height of the tree upto which the squirrel climbed.
Solution-
Potential energy of a body = mgh
34.3 = 0.5×h (mg = 0.5kg)
h = 34.3/0.5
= 68.6 m

Create a city of your choice and assign each of the major organelles from our guided notes to a part of the city.
Draw your city on a piece of paper. Use your creativity and imagination!
Write your analogy to show the similarity between the cell part and the part of the city. Be sure to explain the reasoning behind your analogies. The cell analogies and functions should be written.
Example- The nucleus controls the cell just like how town hall coordinates a city.
You will create this on a sheet of paper or on a digital document that works best for you.
Make sure to include each organelle, what it does, and what it could represent within a city! Be creative!
Answer:
A cell is like a city
Example
The nucleus controls the cell just like how the town hall coordinates a city.
1) The vacuole is a supply centre just as they are the large groceries in the city.
2) The mitochondrion is the supplier of ATP to the cell, as well as the electric power plant in the city.
3) The Golgi Apparatus is responsible for packaging and modifying proteins as well as distributing chemical messages in the cells just as the post office works in the city.
4) The ribosomes they produce from raw material RNA finished products named proteins as the factories do.
5) The cell wall protects the cell as the fortifications do in the city.
6) The cell Membrane allows the communication of the cell with the environment through the transport of information just like the city limits, through tollbooth or carrier proteins.
7) Lysosomes process cellular material down to simpler and smaller molecules like the city's recycling plant does.
8) The endoplasmic reticulum allows the movement of proteins in the cell as do the roads in the city.
Explanation:
Unfortunately, I do not know the organelles that you present in your guide, however, I give you an example with the most important.
The vacuole is responsible for storing food, liquids and wastes and/or enzymesThe mitochondrion is the energy-producing organelle synthesizing ATPThe Golgi apparatus handles synthesized proteins to transport them to other places in cellsRibosomes are responsible for reading DNA and producing proteins.The cell wall gives structure and protects the cell.The cell membrane regulates transport into and out of the cell.Lysosomes are responsible for degrading intracellular material. The endoplasmic reticulum is a network of membranes that allows the movement of proteins and other molecules.Which part of the onion cell is labeled A?

due to my reasons we all know we are in the end time the trumpet can just come from else where and true believer will accomplish the kingdom
Answer:
These species are not able to survive and hence become extinct. Human activities such as fragmentation cause the genetic diversity to become lowered for organisms of a species. As a result, a disaster such as a disease results in killing all the organisms of a species present in a community.

How many kingdoms are there in the domain Eukarya? O A. 1 O B.2 O c. 4 O D. 3
Answer:
There are 4 kingdoms
There are currently four kingdoms in the domain named Eukarya. The correct option is c.
What is domain?In biological classification, a domain is a taxonomic category above the kingdom level. Bacteria, Archaea, and Eukarya are the three domains of life.
These domains are defined by differences in cell structure, biochemistry, and other characteristics of the organisms that inhabit them.
Bacteria and Archaea are both prokaryotic domains, whereas Eukarya is a eukaryotic organism domain that includes animals, plants, fungi, and protists.
In biology, a kingdom is a taxonomic rank made up of smaller groups known as phyla (or divisions, in plants).
Historically, the highest taxonomic rank, or the most general taxon used in classifying organisms, is kingdom.
Animalia, Plantae, Fungi, and Protista are the current kingdoms in the domain Eukarya.
Thus, the correct option is c.

How does this model support the conclusion that cells need to have a high amount of surface area relative to their total volume?
Answer:
Due to increase of surface area, the nutrients move efficiently inside the cell.
Explanation:
The cells need to have a high amount of surface area as compared to their total volume because with increase of surface area, the nutrients move efficiently inside the cell. A large surface area to volume ratio indicates that the cell can be efficient in moving nutrients and waste materials around using through the process of diffusion but when the volume increases instead of surface area, the efficiency of the cell decreases, and cells won't be able to do its job efficiently.
Draw a food chain that includes the ants, fungal gardens, mold, and bacteria. Label the drawings and add arrows to show how the four organisms interact.
Answer:
Symbiosis and decomposers.
Explanation:
The ants feed on both plants and insects so we can say that ants are omnivorous. They make a symbiotic relationship of mutualism with fungi such as mold which helps the ants to breakdown the cellulose of plants whereas plants provide habitat to fungi. The bacteria feeds on the dead body of ants and release nutrients by performing the function of decomposition so bacteria acts as decomposer so in that way these four organisms interact with each other.
