Which of the following is an example of a lipid?
phospholipid.
triglyceride
fats and oils.
all of these
Answer:
phospholipid
Explanation:
Phospholipids, triglycerides, fats, and oils are examples of a lipid. Therefore, option D is correct.
What are lipids?Fatty, waxy, or oily molecules are referred to as lipids. They are soluble in organic solvents but insoluble in polar solvents like water. Steroids, phospholipids, oils, and waxes are examples of lipids. They are usually referred to as fats and oils.
Since lipids may be broken down to provide significant amounts of energy, one of their primary biological purposes is the storage of energy. The structural elements of cell membranes and a number of the body's messengers and signaling molecules are also formed by lipids.
Cell membranes, cholesterol, blood cells, and the brain are just a few places where they can be found in the human body.

1. What is the proper order of succession?
A. climax community- pioneer species-primary succession- secondary succession
B. pioneer species-primary succession-secondary succession-climax community
(I WILL MARK BRAINLEST )! or however you spell it !!
The answer fam is......... B. pioneer species-primary succession-secondary succession-climax community
"Primary succession begins in barren areas, such as on bare rock exposed by a retreating glacier. The first inhabitants are lichens or plants—those that can survive in such an environment. Over hundreds of years these “pioneer species” convert the rock into soil that can support simple plants such as grasses. These grasses further modify the soil, which is then colonized by other types of plants. Each successive stage modifies the habitat by altering the amount of shade and the composition of the soil. The final stage of succession is a climax community"

Lactic acid fermentation is a type of anaerobic respiration that occurs in organisms such as:
1) Bacterial Cells
2) Animals
3) Yeast Cells (fungi)
4) Plants
Answer:
animals
Explanation:
lactic acid fermentation occurs when there is not enough oxygen to make aerobic respiration. glucose will be converted into pyruvates and those pyruvates will become lactates to reduce NADH to NAD+
Lactic acid fermentation is a type of anaerobic respiration that occurs in organisms such as bacterial cells.
What is anaerobic respiration?The term "anaerobic" means "without oxygen". There is no need for oxygen in this type of cellular respiration to produce energy. Smaller creatures require energy to survive in the lack of oxygen since there is not enough oxygen available for them to breathe.They engage in anaerobic respiration, which they use to generate the energy they require.What is lactic acid fermentation?Lactic acid fermentation is a metabolic process that converts one molecule of glucose to two molecules of lactic acid. It occurs in the cytoplasm of the cell.Bacteria convert pyruvic acid into lactic acid when anaerobic conditions, or conditions without oxygen, exist. Not much energy is released throughout this process.

EXplain why a complex food web is better than a simple food chain for the survival of the community.
Answer:
A complex food web is better than the simple food chain because the food web links together the relationships between a producer, consumer, and decomposers. Another reason why a complex food web is better than a simple food chain is that if a particular species is eliminated from a food web, the entire ecosystem has a lower chance of collapsing due to that loss. A food web can more readily react to changes in the environment that impact one or more species.
Hope this helps :)
Answer:
(Answers may vary.)
A complex food web is more important than a simple food chain for the survival of a community. The food web is more important because it is more intricate and adaptive than a food chain. A community houses many species. These species are dependent on each other for energy and food. So, there are multiple relationships of energy transfer involved.
A food chain is linear, which means that each predator has only one source of food. So the predator is vulnerable if the food source is depleted through disease or a change in environmental conditions. Whereas in a food web, each predator has many food sources. A complex food web provides multiple preys to species at a higher trophic level. As a result, a food web illustrates the feeding relationships between many species at different trophic levels in an ecosystem.

Answer:
Isotonic
Explanation:
It is isotonic because the liquid/molecules appear to be flowing in and out of the cell evenly. A hypertonic solution would mean the cell would shrink because there would be less liquid/molecules inside the cell compared to the outside. A Hypotonic solution would be a greater concentration of the liquid inside the cell compared to the outside, the cell would lyse or burst
Answer: hypotonic

Your friend is taking a Genetics lab at UT. She needs some help with a lab report so she calls you for some advice—she knows you will be able to help since you are taking Genetics. After analyzing data from a three point cross she has lost her lab manual. The only thing she can find is that the Interference in this cross was 0.68. She remembers a testcross was done with a heterozygous female and that the genes being analyzed were forked bristles, crossveinless wings, and white eyes. She also tells you that there is an equal distance between these genes. What is this distance if she counted 3 double crossover progeny out of 500 total progeny?
Answer:
The distance between these genes is 0.9375 MU
Explanation:
To calculate the coefficient of coincidence, CC, we must use the next formula:
CC= observed double recombinant frequency/expected double recombinant frequency
Note:
observed double recombinant frequency=total number of observed double recombinant individuals/total number of individuals expected double recombinant frequency: recombination frequency in region I x recombination frequency in region II.The coefficient of interference, I, is complementary with CC.
I = 1 - CC
Available data:
• Interference = 0.68
• Equal distance between genes
• 3 double crossover progeny
• Total number of individuals in the progeny, N = 500
We know that
CC= observed double recombinant frequency/expected double recombinant frequency
CC = (total number of observed double recombinant individuals/total number of individuals)/( recombination frequency in region I x recombination frequency in region II)
I = 1 - CC
So, all we need to do is to clear each formula with the data given in the problem:
I = 1 - CC
0.68 = 1 - CC
CC = 1 - 0.68
CC = 0.32
CC = observed double recombinant frequency/expected double recombinant frequency
We already know the value of CC, and we know how to calculate the observed double recombinant frequency. But we need to calculate the expected double recombinant frequency. So,
0.32 = (3/500)/(RF-RI x RF-RII)
0.32 = 0.006 / (RF-RI x RF-RII)
(RF-RI x RF-RII) = 0.006/0.32 = 0.01875
We know that the expected double recombinant frequency is the recombination frequency in region I multiplied by recombination frequency in region II. In this case, it equals 0.01875
We also know that there are equal distances between genes, so now we need to divide 0.01875 by 2
0.01875 /2 = 0.009375
The genetic distance will result from multiplying that frequency by 100 and expressing it in map units (MU) or centiMorgans (cM). Now we must multiply each recombination frequency by 100 to get the genetic distance
0.009375 x 100 = 0.9375 MU or cM

. How are mineral deposits formed around vents?
Answer:
When hot, metal-laden water spews from vents and mixes with the cold ocean, the metals precipitate. Large piles of sulfide accumulate on the seafloor and are eventually buried by sediments, modified by heat and pressure in the crust, and uplifted. Some are exposed on land when erosion removes the overlying rocks.

them
Answer:
The correct answer is - option C. alligators; their tails dig holes that hold water during times of drought, and this water is used as a source for drinking water by many species.
Explanation:
Beavers are keystone species as they help other species to get habitat and also help plants to grow by the holes or dams they make. Kudzu is a keystone species of an ornamental plant which lowers the soil erosion in their abundance.
Red cocaded woodpecker is a keystone species as they create pits in the pine trees that are helpful for other species to live.
Alligators also keystone species but not for digging holes and hold water but the influencing the prey and maintaining the animals in the ecosystem.
