Why does an increased amount of biodiversity/complexity in an ecosystem allow it to respond better after a disturbance?
Answer:
Higher biodiversity seems to be associated with a better response to disturbance events
Explanation:
Biodiversity means 'the variety of life'. Disturbance processes modify the environment and also affect demographic processes such as growth, recruitment, survivorship, etc., thereby producing changes in biodiversity. In an ecosystem, biodiversity contributes to its sustainability. In this regard, it has been shown that disturbance events are less important in species-rich ecosystems such as tropical wet forests compared to less rich ones (such as dry forests). The communities with higher biodiversity levels are known to be more productive in terms of biomass, and thus they seem to be more stable (and successful) to disturbance events.

A. Red blood cells coagulate wounds; white blood cells defend
against bacteria.
B. Red blood cells are respiratory, white blood cells are circulatory.
C. Red blood cells hold oxygen; white blood cells hold carbon
dioxide.
D. Red blood cells are in veins, white blood cells are in arteries.
Answer:
A. Red blood cells coagulate wounds; white blood cells defend against bacteria.
The difference between white and red blood cells are:
A. Red blood cells coagulate wounds; white blood cells defend against bacteria.
Differences between red and white blood cells:Red platelets don't have a core on development. WBCs are portrayed by the presence of an enormous focal core. Because of the presence of hemoglobin, these cells seem red in variety. While white blood cells are dismal, as they have no color.
Red and white blood cells have two main functions:
Carrying oxygen, and defense against microbial attack.
Thus, option A is correct.

What causes a tornado to form?
Water vapor condenses, giving off energy.
Wind over ocean water forces water vapor upward.
A warm, moist air mass collides with a cold, dry air mass.
Air pressure changes suddenly, causing rapid air movement.
A warm, moist air mass collides with a cold, dry air mass
A warm, moist air mass collides with a cold, dry air mass causes a tornado to form. Thus, the correct option is C.
What causes a tornado?A tornado is a violently rotating column of air which is extending from the base of a thunderstorm down to the ground level. Tornadoes are the disasters which are capable of completely destroying well-made structures, uprooting trees, and the hurling objects through the air such as deadly missiles.
Tornadoes are developed from severe thunderstorms in the warm, moist, unstable air along and ahead of the cold fronts. Such thunderstorms may also generate large hail and damaging winds. When intense springtime storm systems produce large, persistent areas which support tornado development, major outbreaks can occur in the atmosphere.
Therefore, the correct option is C.

A lab group was working and did not turn off their hot plate. They left their beaker on it with water boiling and a thermometer in the beaker. The water evaporated and the thermometer exploded.
a) Explain why it is important to always turn off the hot plate and to be sure it is cool before putting it away.
b) There are two beakers. One was just taken off the hot plate, while the other was sitting on the lab table. Can you tell which one is hot just by looking? Explain.
Answer:
It is always important to turn off the hot plate because objects around it can catch on fire, things could explode if something is left on it, or someone could get injured.
Yes, you can tell if the water is boiling or if there is steam in the beaker/condensation.
Hope that helps and have a great day!
Answer:
my answer for a is its important to turn off the hot plate because it will possibly burn or hurt someone who bumps into it or touch's it
Explanation:
answer for b is that you can tell which ones hot because of the steam coming out of the beaker
How are ions and small polar molecules such as glucose able to move across plasma membranes?
A) osmosis
B) endocytosis
C) using a transport protein
D) through gaps in the phospholipid bilayer
Answer:
Answer is C
Explanation:
Although ions and most polar molecules cannot diffuse across a lipid bilayer, many such molecules (such as glucose) are able to cross cell membranes. These molecules pass across membranes via the action of specific transmembrane proteins, which act as transporters.

The data would be more accurate if she carried out all the observations in one day so weather conditions would be constant.
The data would be more valid if she made the observations daily for two months.
The data she collected is inaccurate because the investigation is not repeatable.
The data she collected cannot be plotted in a line graph because it is qualitative.

Which of the following distinguishes this bacterial cell from eukaryotes?
DNA in the bacterial cell is always in contact with the cytoplasm, and all eukaryotes have DNA located inside a nucleus.
The bacterial cell is a unicellular organism, and all eukaryotes are multicellular.
Ribosomes are found in the cytoplasm of the bacterial cell, and eukaryotes do not have ribosomes.
The bacterial cell has both a cell membrane and a cell wall, and eukaryotes have only cell membranes.
Answer: DNA in the bacterial cell always in contact with the cytoplasm, and all eukaryotes have DNA located inside a nucleus
Explanation:that’s what I put on the test got 100/100
DNA in the bacterial cell always in contact with the cytoplasm, and all eukaryotes have DNA located inside a nucleus. Thus option A is correct.
what is the structure of DNA ?DNA is the double helical structure, a carrier of genetic material present in a chromosome of nucleus; Bothe prokaryotic and eukaryotic cell contain DNA.
It is made up of nitrogenous base, deoxyribose sugar , and a phosphate group, there are four types of nitrogenous base which has been classified into purine and pyrimidine based on the structure.
Purine refers to adenine (A) and guanine (G) while a pyrimidine, refers to cytosine (C) and thymine (T), purine can pair with pyrimidine by forming different number of hydrogen bond.
DNA is a twisted helical structure form a right-handed helix, here Adenine can pair with Thymine by two hydrogen bond and Guanine can pair with Cytosine by three hydrogen bond.
Thus option A is correct.
