Scientists collect data on the size and number of worms that three bird species prefer to eat. The feeding preference data
of the three bird species are shown.
Bird Feeding Preferences
Worms Eaten
(per bird)
Key
. - Bird Species 1
Bird Species 2
........ Bird Species 3
Worm Size
Which statement is supported by the data?
A
Selection pressure from the three bird species will result in a worm population with only small and large worms.
B
At least three different species of worms are eaten by the three bird species.
С
competition for food exists within any of the three bird species.
Less competition between the three bird species will be observed if a range of differently sized worms is available.
Answer:
D
Explanation:Due to the availability of worms hence the 3 different species, the different birds will have less competition because they feed on different species. (Also did this on castle learning and it was correct)

Ethylene oxide is a highly flammable gas used to sterilize medical equipment. To prevent a fire hazard, ethylene oxide should only be used in an area: without sparks or flames. ... To prevent a fire hazard, ethylene oxide should only be used in an area: without sparks or flames.
To prevent a fire hazard, ethylene oxide should only be used in an area without sparks or flames. Thus, the correct option for this question is D.
What is ethylene oxide?Ethylene oxide may be defined as a type of highly flammable gas that is significantly utilized in order to sterilize medical equipment. It is a colorless gas with a sweet odor.
It is used primarily to produce other chemicals, including antifreeze. In smaller amounts, ethylene oxide is used as a pesticide and a sterilizing agent.
As this ethylene oxide is a highly flammable gas one must be required to keep this in a place or an area that is free from sparks or any other kinds of flames.
Therefore, to prevent a fire hazard, ethylene oxide should only be used in an area without sparks or flames. Thus, the correct option for this question is D.

How does hemophilia affect homeostasis?
Answer:
Explanation:
Homeostasis works by creating the opposite effect in order to counteract a change in the body. One of these effects is blood coagulation. This means that blood is thickened and hardened in order to stop blood flow when there is a cut, open wound, or internal bleeding. Hemophilia on the other hand completely prevents blood from coagulating which makes the homeostasis process obsolete. Without blood coagulation, an individual can bleed to death from any small cut which is usually non-life-threatening.

Answer:
So that in a guinea pig cross in the offspring the recessive trait —long hair— can be observed in 25%, the most probable genotype of the parents is heterozygous Ss.
Explanation:
In guinea pigs, for the characteristic hair length, short hair is the dominant allele and long hair is the recessive one.
In order for 25% of the offspring to express the recessive characteristic, the parents must have a recessive genotype, which can be seen in Punnett's Square:
P: Ss X Ss
Alleles S s
S SS Ss
s Ss ss
Where the offspring is:
50% Ss with short hair phenotype 25% SS with short hair phenotype 25% ss whose phenotype would be long hair.According to this, heterozygous parents for the characteristic long hair in guinea pigs have a 25% chance of having offspring with long hair.

How does a plant cell differ from an animal cell? Group of answer choices A plant cell can make its own glucose; an animal cell cannot A plant cell cannot synthesize proteins an animal cell can. A plat cell cannot perform cellular respiration; an animal cell can.
Answer:
plant cell can make its own glucose; an animal cell cannot
Explanation:
Chloroplasts are found in plant cells, but not in animal cells. The purpose of the chloroplast is to make glucose that feed the cell's machinery. Photosynthesis is the process of a plant taking energy from the Sun and creating glucose.

The components that make up the genetic code are common to all organisms. If a segment of a gene contains 27 nucleotides, none of which are stop or starts codons, how many amino acids does this segment code for?
Answer:
9 amino acids
Explanation:
A segment of a gene that has 27 nucleotides will code for 9 amino acids.
Each codon on the gene potentially represents an amino acid and a codon is made up of 3 nucleotides each. Hence, in order to find out the total number of amino acids that a gene segment with 27 nucleotides can code for, the number of nucleotides should be divided by 3.
number of amino acids = number of nucleotides/3
27/3 = 9 codons/amino acids
At a high school, students can choose to enter through one of three doors. Custodians noticed that door #3 was always getting broken and suggested that more students use that door because it has a hands-free opener. Science minded students counted the number of students entering each door to see if the custodians were right.
The number of students to enter each door was counted; the data is summarized in the table below:
Choose the best statement:
A. The null hypothesis should be accepted.
B. The difference between the number of students who use each door cannot be explained by chance alone.
C. The difference between the number of students who use each door is due to chance alone.
D. There is no statistical difference between the number of students who use each door.

Adult giraffes eat about 75 pounds of food in a day. On average, an area can provide 450 pounds of food per day for giraffes. Based on this information only, what is the carrying capacity for adult giraffes in this area?
Answer:
6 giraffes
Explanation:
If an area can provide 450 pounds of food for the giraffes and the giraffes eat 75 pounds of food per day, you can divide:
450 by 75= 6
6 giraffes is the capacity for that area

What is the name of length of time needed for us to pay back our oxygen debt?
O2 oxygen debt time may vary from individual to individual, but the average is 2 minutes for normal individuals.
What is O2 Oxygen Debt?Oxygen debt is a physiological phenomenon that occurs when someone consumes oxygen at a faster rate than it can be replaced, leading to an oxygen deficit that causes increased respiration as the body tries to replace used oxygen.
With this information, we can conclude that the time of o2 oxygen debt can vary from individual to individual, but the average is 2 minutes for normal individuals.

how are fossil fuels and algal oils alike and how are they different
Answer:
Despite a substantial literature using life cycle assessment (LCA) approach, the extent to which second and third generation biofuels are more sustainable than the first generation remains a subject of debate. Although the existence of limitations due to LCA variability and uncertainty, this paper intends to determine global tendencies based on a statistic and critical interpretation of previously published study results, reviewing 61 recent papers addressing an environmental evaluation of microalgae biofuels. Such information is compared to the same impact indicators for fossil fuels and for ethanol and biodiesel from terrestrial crops in Europe and Brazil. For each case, the system boundaries and the methodological choices were precisely described. The sustainability potential of all biofuels was evaluated by the Global Warming Potential (GWP), the Energy Ratio (ER) and the Land Use (LU), allowing a broad estimation of the biofuels’ contribution to climate change mitigation, their net energy efficiency and their competiveness with food production chain.
