Answer:
a. far fewer black beetles would be consumed
Explanation:
Since there are more trees with black bark, black beetles have a better chance of hiding. The white and brown beetles would be consumed more by the predators.
If the number of trees with black bark is significantly higher than those with white or brown barks, far fewer black beetles would be consumed.
With the availability of black, white, and brown-bark trees in the environment, black, white, and brown McIver beetles would be able to use the trees to camouflage or hide from their predator respectively.
Camouflage is a kind of visual mimicry in which a combination of materials such as color or light is used to conceal the identity of an object. Thus, black beetles can camouflage with black-barked trees, white beetles with white-barked trees, and so on.
Now, if there are significantly more black bark trees as compared to white and brown in an environment with black, white, and brown beetles, it means that more black beetles would be able to escape predation by camouflaging.

Answer:
B.They hadn't turned the telescope toward the night sky.
They thought Earth was the center of the universe. Option D is the correct answer.
What was the time when Galileo saw Jupiter's moons ?Galileo saw these Jupiter's moon around 1600 and the decade.
Galileo was almost unable to just see then every moon on the each night and the reason for this is that some of just moved away too too far in process of the orbit for the weaker telescope to just view. In that case clearly they just orbited then Jupiter in the same way and as the Moon orbits Earth.
And if the moons can orbit the planet, in that case perhaps it is true where the Earth orbited Sun after all in the end . Galileo hadn't seen moons around the Jupiter as it is almost failing geographic observations. Jupiter's moons although do not appear to orbit Earth.

Explain two possible reasons why a person who looks well could still be a source of infection microorganism?
Answer:
- many pathogens exhibit a latency (asymptomatic) period of incubation
- usually, pathogens need to replicate many times in order to be transmitted between hosts (i.e., they need to increase the pathogenic load)
Explanation:
The latency stage refers to the period between being exposed to a particular pathogenic microorganism (for example, a virus) and has symptoms associated with the disease caused by such pathogen. Generally, this incubation stage is asymptomatic, thereby a person will look healthy during this period. Moreover, the pathogenic load (usually known as the viral load in viral infections) can be defined as the number of pathogenic microorganisms in an infected person's blood. During the first stages of infection, the pathogenic load usually is low, whereby a person can also look healthy during this period.
list ways in which invertebrates compensate for not having a spine
Invertebrates can be simply identified as animals that do not have a backbone. To compensate for the lack of an internal skeleton, most invertebrates have an external skeleton that protects their soft, inner body.
Invertebrates compensate for their inability to possess a backbone ( spine ) by having ; An external skeleton ( exoskeleton )
What are invertebrates ?Invertebrates are animals without backbone and also lacks an internal skeleton. The exoskeleton present in invertebrates helps in the protection of the outer surface of the organism from external stimuli and also aids in the movement through internal muscles.
Invertebrates compensates for the absence of a backbone through the possession of an exoskeleton which performs similar function just like the endoskeleton.
Hence we can conclude that Invertebrates compensate for their inability to possess a backbone ( spine ) by having ; An external skeleton ( exoskeleton ).

Rock pocket mice live in the deserts of the American southwest. Ancestral pocket mice all had light-colored coats that blended in
with the region's rocks and sandy soil, keeping the mice hidden from predatory owls. About 1.7 million years ago, a series of
volcanic eruptions spewed out wide trails of black lava into the middle of rock pocket mouse territory. Currently there are two color
morphs of rock pocket mice: light-colored mice that are typically found in habitats with sandy soil, and dark-colored mice that are
typically found in habitats with dark-colored lava rocks.

Some bacteria possess antibiotic resistance, as well as the ability to survive through adverse conditions. Where in this type of bacteria is the DNA located?
a. nucleoid, fimbriae , and plasmids
b. fimbriae, nucleoid, and endospore
c. endospore, fimbriae, and plasmids
d. plasmids, nuclouid, and endospore
Answer:
d. plasmids, nucleiod, and endospore
Explanation:
Bacteria are prokaryotic organisms i.e. they do not possess a well defined nucleus in their cells. However, according to this question, some bacteria are said to possess antibiotic resistance, as well as the ability to survive through adverse conditions. These two characteristics of some bacteria is attributed to the possession of a plasmid and endospore respectively.
A plasmid is a circular extra-chromosomal DNA found in bacterial. It is termed "extra" because it is different from the DNA of the bacteria and carries different genes. The genes contained in the plasmid often gives the bacteria added advantage like antibiotic resistance. On the other hand, endospores are asexual spores produced by bacteria in order to withstand adverse environmental conditions like drought etc.

Put the following events in the correct order:
A. The amino acid sequence built from the mRNA varies
B. As the DNA sequence varies the mRNA sequence that is created during transcription
varies,
C. Since the structure of the protein determines its function we see variation in the traits
expressed due to how that protein ultimately functions based on its shape
D. This causes the structure of the protein to be different because different amino acids
are used.
Answer:
B → A → D → C
Explanation:
This question involves gene expression, which is the process of how gene is used to synthesize proteins that determine the phenotype or traits of an organism. Gene expression involves two processes namely: transcription and translation.
- Transcription is the process whereby a DNA template is used to synthesize a mRNA sequence.
- Translation is the process whereby the mRNA transcript is used to synthesize an amino acid sequence, which eventually becomes a protein.
Based on this, the correct order of sequence of events given in this question will be:
- As the DNA sequence varies, the mRNA sequence that is created during transcription varies (transcription).
- The amino acid sequence built from the mRNA varies (translation).
- This causes the structure of the protein to be different because different amino acids are used.
- Since the structure of the protein determines its function we see variation in the traits expressed due to how that protein ultimately functions based on its shape.

Samples of different materials A and B have the same mass, but the sample
of B is higher in density. Which statement could explain why this is so?
A. The particles that make up material B are more closely packed
together than the particles that make up material A.
B. The sample of material B has greater volume than the sample of
material A
C. The particles that make up material A have more mass than the
particles that make up material B.
O D. The particles that make up material A are more closely packed
together than the particles that make up material B
Answer: A. The particles that make up material B are more closely packed
Explanation:
The particles that make up material B are more closely packed together than the particles that make up material A. The correct answer is A. The particles that make up material B are more closely packed together than the particles that make up material A.
What is density ?Density is defined as mass per unit volume. Since the samples of material A and B have the same mass, but material B has a higher density, this means that material B has a smaller volume than material A.
The density of a material is related to the way its particles are arranged and packed together. When the particles are more closely packed together, the material will have a higher density. Therefore, option A is the correct answer that explains why the sample of material B is higher in density than material A.
If the samples of material A and B have the same mass, but the sample of B is higher in density, this means that the mass of the particles in material B is greater than that in material A, even though they have the same mass. This is because the particles in material B are more closely packed together, which means that there are more particles in a given volume of material B compared to the same volume of material A.
For example, imagine a container of 1 liter volume containing material A and another container of 1 liter volume containing material B. If the mass of material A and B in each container is the same, this means that the container of material A would have a greater volume than the container of material B. This is because the particles in material A are less closely packed together than the particles in material B.
Therefore, the key difference between the samples of material A and B is the way their particles are arranged and packed together, which determines their density.
