what is the difference between camouflage and mimicry
Answer:
Camouflage would be a process of an individual or creature disguising themself with their surroundings or environment. It can be used to disguise their identity, presence, and movement. While mimicry is the act of copying or mimicking other individuals. When referring to animals though, it is the evolved resemblance of another creature and can be used for the protection of one-self. The Viceroy and Monarch butterfly is a good example of mimicry since the monarch butterfly is poisonous and the viceroy is harmless. Because of this, many creatures know not to eat monarch butterflies and would be cautious around the viceroy as well, because of the striking resemblance between the two. Hope this could help!

Explanation:
An organism that reproduces sexually has a diploid number of 30. How many
chromosomes will a gamete of this organism have?
Answer:
Gamete of organism has a haploid number of chromosomes.
2n = 30
n = 15
A diploid cell containing 30 chromosomes will result in 15 chromosomes in each of the 4 daughter cells after meiosis occurs.
After first nuclear and cellular division (Meiosis I), each daughter cell will only have 15 chromosomes as homologous chromosomes are broken apart at Anaphase I of meiosis I. Chromosomal number is halved. After the second nuclear and cellular division (Meiosis II), each daughter cell will also have 15 chromosomes. This time, instead of the chromosomal number being halved, their chromosomal contents are halved. Sister chromatids are separated at Anaphase II of Meiosis II, resulting in daughter chromosomes each.

Mountain chains in northern Europe and West Africa match the Appalachian Mountains in terms of their ages and the sequences of rock layers that make them up. in 3-5 sentences analyze these observations and explain what conclusions can be drawn from them.
The above observation shows that the mountain chains in Northern Europe and West Africa are part of the Appalachian Mountains as a result of the same age, matching of rocks, etc
A mountain chain simply means a row of high mountain summits or a contiguous ridge of mountains within a larger mountain range.
The theory of plate tectonics establishes a co-relation with these mountain chains by understanding their movements. It was shown that Europe and Africa were part of the same landmass in the past. Due to the gradual movement of plates, both continents move apart.

Describe how scientists make inferences on whether water is polluted or not
Answer: Water that's safe to drink should ideally be clear with no odor or funny taste. One way to tell if water is contaminated is to look for turbidity, or cloudiness. While cloudy water isn't necessarily dangerous to your health, it could signal the presence of unsafe pathogens or chemicals.
Explanation:
Drinkable water should ideally be transparent and taste and smell normal. Look for turbidity, or cloudiness, as one indicator that water is contaminated.
What is drinkable water?Surface water and groundwater are the two sources of potable water, also referred to as drinking water. The level of treatment applied to this water satisfies both state and federal standards for potable water.
The indirect potable reuse (IPR) and direct potable reuse (DPR) processes are the two basic ways to turn wastewater into potable water (DPR).
Foggy water may not always be harmful to your health, it may indicate the presence of germs or chemicals that are toxic.

Please help!! What are Okazaki fragments?
Explanation:
Okazaki fragments are short sequences of DNA nucleotides (approximately 150 to 200 base pairs long in eukaryotes) which are synthesized discontinuously and later linked together by the enzyme DNA ligase to create the lagging strand during DNA replication.[1] They were discovered in the 1960s by the Japanese molecular biologists Reiji and Tsuneko Okazaki, along with the help of some of their colleagues
During DNA replication, the double helix is unwound and the complementary strands are separated by the enzyme DNA helicase, creating what is known as the DNA replication fork. Following this fork, DNA primase and DNA polymerase begin to act in order to create a new complementary strand. Because these enzymes can only work in the 5’ to 3’ direction, the two unwound template strands are replicated in different ways.[2] One strand, the leading strand, undergoes a continuous replication process since its template strand has 3’ to 5’ directionality, allowing the polymerase assembling the leading strand to follow the replication fork without interruption. The lagging strand, however, cannot be created in a continuous fashion because its template strand has 5’ to 3’ directionality, which means the polymerase must work backwards from the replication fork. This causes periodic breaks in the process of creating the lagging strand. The primase and polymerase move in the opposite direction of the fork, so the enzymes must repeatedly stop and start again while the DNA helicase breaks the strands apart. Once the fragments are made, DNA ligase connects them into a single, continuous strand.[3] The entire replication process is considered "semi-discontinuous" since one of the new strands is formed continuously and the other is not.[4]
[2]During the 1960s, Reiji and Tsuneko Okazaki conducted experiments involving DNA replication in the bacterium Escherichia coli. Before this time, it was commonly thought that replication was a continuous process for both strands, but the discoveries involving E. coli led to a new model of replication. The scientists found there was a discontinuous replication process by pulse-labeling DNA and observing changes that pointed to non-contiguous replication.

name three different releasers that can trigger a behavior
Reflex, taxis and kinesis are the different releasers that can trigger a behavior.
What is Behavior?Behavior is defined as the range of actions and behaviors performed by individuals, organisms, systems or artificial entities in some environment, whose systems may include other systems or organisms as well as inanimate physical environments.
These play important roles in survival, long-term and short-term health, and emotional and physical well-being. While some behaviors are innate, and others are conscious choices. Behavior is the result of a complex interaction between genetics and environment, and includes emotional and physical actions and reactions.
The simplest example of an innate behavior which is a reflex action: an involuntary and rapid response to a stimulus, or cue.
Thus, reflex, taxis and kinesis are the different releasers that can trigger a behavior.

Mountain chains in northern Europe and West Africa match the Appalachian Mountains in terms of their ages and the sequences of rock layers that make them up. in 3-5 sentences analyze these observations and explain what conclusions can be drawn from them.
According to the statement, it can be concluded that the three mountains were formed around the same geological era. Additionally, they have similar layers due to the sedimentation and metamorphization processes.
Since its emergence, the Earth has experienced different physical and chemical phenomena that have influenced changes in it. In the case of the lithosphere and the Earth's crust, they have been influenced by phenomena such as
Volcanism The rock cycle The wind The rainfall Among other
Additionally, geologists have developed methods of studying the crust to know the age and composition of the layers of the Earth's crust. According to this, it can be established that these three layers are of the same age because their composition of layers is studied and the materials and distribution of the layers match, that is, they were formed at the same time.
This coincidence in distribution is explained through the processes of sedimentation of materials and their metamorphization.
