Ticks
Ticks belong to a family called Acarina, which also contains mites. Ticks eat by taking blood from
other organisms such as wallabies, lizards, echidnas and occasionally humans. In humans this can
lead to symptoms such as itching, head aches and in extreme cases flu like symptoms, facial
paralysis, and meat allergy.
1. Identify the relationship a tick has with its host. Justify your answer [3]
Answer:
Parasitism
Explanation:
Parasitism is a form of relationship in which one of the organism is being harmed while the other benefits. The organism being harmed is usually called the HOST while the organism that benefits is called PARASITE. Parasites often inflict certain health-related conditions on their hosts.
According to this question describing the mode of feeding of ticks, they are said to eat by taking blood from other organisms such as wallabies, lizards, echidnas and occasionally humans, which are all HOSTS.
In human hosts, this relationship with ticks can lead to symptoms such as itching, head aches and in extreme cases flu like symptoms, facial paralysis, and meat allergy etc. From the description above, it is clear that TICK has a PARASITIC RELATIONSHIP with its host as it brings only harm to them and benefits itself.

How does cooling of magma affect crystal size?
A) Slow cooling creates small crystals
B) Fast cooling creates both large and small crystals.
C) Slow cooling creates large crystals
D) Fast cooling create large crystals
Answer:
When magma cools, crystals form because the solution is super-saturated with respect to some minerals. If the magma cools quickly, the crystals do not have much time to form, so they are very small. If the magma cools slowly, then the crystals have enough time to grow and become large.
Answer:
I learned about this, Uhm...
C is the right answer bc igneous rocks cool and form crystals.
Lava, since it comes out of a volcano, cools faster and has smaller crystals since they could not be developed enough.
Magma, still underground, cools slower than lava because of all the density and heat, which causes bigger crystals.
Hope this helps :)

How does the DNA change during meiosis?
Answer:
Scotland
Law is a surname, of English, Scottish, Cantonese, or Chinese origin. In Scotland, the surname means dweller at the low; as in a hill. Another origin of the surname is a contraction of Lawrence, or Lawson.
Explanation:
Answer:When recombination occurs during meiosis, the cell's homologous chromosomes line up extremely close to one another. Then, the DNA strand within each chromosome breaks in the exact same location, leaving two free ends. Each end then crosses over into the other chromosome and forms a connection called a chiasma.
Explanation: Np
Pairs of chromosomes contain (the same/different) types of genes.
Answer:
The 22 pairs of homologous chromosomes contain the same genes but code for different traits in their allelic forms since one was inherited from the mother and one from the father. So humans have two homologous chromosome sets in each cell, meaning humans are diploid organisms.

Jadon plans on carrying out an experiment involving the burning of steel wool to illustrate the conservation of mass. Steel wool is made of iron. When it is burned it combines with oxygen to form iron(III) oxide.
Which step in his experiment is the most important if he wants his experiment to correctly demonstrate the conservation of mass?
A.
The steel wool should be burned inside of a sealed jar or other closed system.
B.
The steel wool should be burned over a long period of time (at least two hours).
C.
The steel wool should be burned in a room that is at room temperature (20–25°C).
D.
The steel wool should be burned in its entirety sExpected Outcomes – Metals in Hydrochloric Acid
Metal Observations
Copper No reaction even when gently heated
Iron Little initial reaction.
More vigorous reaction when heated.
Positive test for hydrogen gas.
Solution turned from colorless to yellow.
Magnesium Vigorous initial reaction; rapid evolution of gas.
Positive test for hydrogen gas.

Students in Ms. Brown's Science Lab demonstrated several chemical reactions, by placing the each above chemicals in HCl (hydrochloric acid). Unfortunately, the data did not appear to support the Law of Conservation of Matter in any of the experiments. The recorded Mass of the Reactants did not match the Mass of the Products. Based on the expected outcomes listed in the table above, what might be a reason that their demonstrations were not successful?
A.
They only used metals
B.
They perfomed the experiment in a closed system
C.
The experiment was not performed in a closed system
D.
They didn't use enough HCl that no iron is left in its original state.
Answer:
1) A chemical reaction is shown.
SnO2 + H2 → Sn + H2O
What is true about this chemical reaction?
B.
It is unbalanced because the mass of the reactants (number of atoms) is greater than the mass of the products (number of atoms).

The true statement about the given chemical reaction is-It is balanced because the mass of the reactants (number of atoms) is equal to the mass of the products (number of atoms). Therefore, the correct options for all the problems are 1-A, 2-A and 3-D.
What is a balanced equation?A balanced equation refers to an equation where the number of atoms of each element is the same on both sides of the equation. The given equation is balanced because the number of Sn atoms and the number of H atoms on the reactant side are equal to the number of Sn atoms and the number of H atoms on the product side.
1. The steel wool should be burned inside a sealed jar or other closed system is the most important step if he wants his experiment to correctly demonstrate the conservation of mass.
2. They didn't use enough HCl that no iron is left in its original state might be a reason that their demonstrations were not successful.
Therefore, the correct options are 1-A, 2-A and 3-D.

How does being really cold affect the nervous system?
Explain the process sleet goes through from the time it leaves the clouds to the
time it hits the ground
Answer:
Sleet is simply frozen raindrops and occurs when the layer of freezing air along the surface is thicker. This causes the raindrops to freeze before reaching the ground. In addition, ice caused by freezing rain can rapidly add weight to tree branches and power lines, causing them to snap or break
Explanation:
When we consider the motion of particles such as the molecules that comprise air, which of the following is False?
Group of answer choices
Molecules move in a random motion and will collide with other particles or a container
As temperature increases, there is an increase in molecular motion
Molecules move from areas of high concentration to areas of lower concentration
As temperature decreases, there is an increase in molecular motion
Answer:
D
Explanation:
If you see two contradictory answers (B & D), one has to be the choice. As temperature increases, molecular motion decreases is false. Diffusion is what choice C is describing and is true.

But if the male Himalayan rabbit's genotype is c(h)c, and it mates with an albino female whose genotype is cc isn't there a 25% chance that the offspring could be albino? and why can't you breed two Himalayan's together to get a Himalayan?
Answer: Go-ogle
Explanation: Is helpful
Please anyone ASAP help
Answer:
C. There is a 25% chance of short offspring.
Explanation:
In the simplified genotypes of a Punnett square cross, we deal with two genotypes. In this case, we are looking at a cross between Tt and Tt. T is dominant and t is recessive, meaning that someone with any genotype with T in it will be tall.
TT, Tt, and Tt will all produce tall offspring, while tt will produce short offspring.
This means there is a 75% chance of tall offspring, or 3:4.
50% or 2:4 are expected to have the Tt genotype.
Only 1 of the 4 will produce short offspring, which is 25%.
