• identical daughter cells
• mitosis
Answers
Answer:
Meiosis is a process in which sex cells, also known as gametes are made. Meiosis is different from mitosis in a lot of ways, one being that mitosis creates identical daughter cells and meiosis creates unique daughter cells. Meiosis is important because it allow for the creation of a meiosis nucleus. Cells produced by meiosis will be used in haploid, where each member of the next generation is genetically unique.
Cells produced in sexual reproduction will have half of the genetic information of body cells and will be genetically unique. This is necessary because when a sperm and an egg fuse together in sexual reproduction. They form a zygote: the first body of a new individual.
The new individual will now have cells that are diploid, meaning they have two sets of chromosomes. They zygote will have to do a lot of mitosis allowing it to grow quickly and ensure that all of its cells are genetically unique.

Bobcats are generally solitary and establish territories of a certain size where they hunt for food. What type of population dispersion would you expect bobcats to have?
Answers
Answer:
Uniform dispersion.
Explanation:
The bobcats' population distribution would be a uniform dispersion because they are distributed in an area in a balanced way. That is to say, that there is space between them and that each bobcat establishes its personal space when hunting and for their daily life. As they are solitary animals, they do not live in groups and only associate with other bobcats to reproduce themselves.
After a devastating forest fire, the surrounding area contained no life. After some time, small plants began to grow along the remaining soil.
Answers
Answer:
Yes.
Explanation:
Yes, small plants began to grow along the remaining soil because of the presence of seeds in the soil that sense suitable environmental condition and come out of the soil. The ashes of burn trees have huge amount of nutrients in the form of minerals that triggers the growth of small plants. After the destruction of forest, new plants grow on that land, this type of phenomenon is called ecological succession.
Answer: CORRECT (SELECTED)
Secondary succession
Explanation:
Secondary succession occurs when a previously occupied area is recolonized after a disturbance kills most, or all, of its community.

All mosquitoes have six diploid chromosomes (2N = 6), and their chromosomes are either submetacentric or metacentric, mosquito cell has 3 chromosomes and is haploid.
What is the difference between haploid and diploid?Three pairs of chromosomes make up the Anopheles mosquito's chromosomal complement: two sex chromosomes As a consequence, when a sperm and egg cell join during fertilization, the resultant zygote has 46 chromosomes.
The number of chromosomes and their shape in mosquitoes are extremely similar mosquito cell has 3 chromosomes, and are haploid.
Therefore, to go from haploid to diploid cells, we only need to double the number of chromosomes. This quantity is denoted by the abbreviation 2n, where n is the number of chromosomes.

A ray of light is passing through a medium making an angle of 45°. If the
refractive index of the medium is 1.4, calculate the angle of refraction. [Ans: 30°)
Answers
Answer: By Snell's law, we can see that the angle of refraction is 30.34°
Explanation:
Snell's law says that:
If a ray in a medium of refractive index n₁, insides with an angle θ₁ in another medium with refractive index n₂, then the angle of refraction θ₂ is given by:
n₁*sin(θ₁) = n₂*sin(θ₂)
We know that:
The incidence angle is 45°, then: θ₁ = 45°
We can assume that the first medium is air, then n₁ = 1
The refractive index of the other medium is 1.4, then n₂ = 1.4
Replacing these in the Snell's law equation we get:
1*sin(45°) = 1.4*sin(θ₂)
Now we can solve this for the angle of refraction:
sin(45°)/1.4 = sin(θ₂)
Asin(sin(45°)/1.4 ) = Asin( sin(θ₂)) = θ₂ = 30.34°
So the angle of refraction is 30.34°
What will be the effect of the damaged DNA? The role of p53 in regulating cell cycle prpgression in response to DNA damage
Answers
Answer:
Damaged DNA causes an increase in the number of mutations in the cell: this is extremely dangerous for the body and in fact this process is at the basis of the birth of cancer cells.
To avoid this, the cell is equipped with some molecular protective systems including the activation of the p53 protein. p53 induces recruitment of DNA damage repair systems and stops cell replication until the damage has been repaired. If the damage cannot be repaired p53 induces cell death through apoptosis

Civil engineers want to determine whether the porosity of surface soil affects aquifer recharge rates
Answers
Aquifer recharge is water that moves from the land surface or unsaturated zone into the saturated zone. Quantitative estimation of recharge rate contributes to the understanding of large-scale hydrologic processes. It is important for evaluating the sustainability of groundwater supplies, though it does not equate with a sustainable rate of extraction. Where contamination of an aquifer is a concern, estimating the recharge rate is a first step toward predicting solute transport to the aquifer. Recharge may cause a short- or long-term rise of the water table. Artificial drainage, e.g., with horizontal porous pipes buried at a chosen depth, is sometimes used to maintain a minimal thickness of vadose zone for agricultural or other purposes.
Recharge rates vary considerably in time and space. Recharge often occurs episodically in response to storms and other short-term, high-intensity inputs. For a given amount of infiltration, temporal concentration enhances recharge because it entails shorter residence times for water in the portions of the soil from which evapotranspiration takes place. Similarly, a larger fraction will become recharge if it is concentrated in narrow channels such as fingers or macropores, not only because this tends to hasten its passage through the unsaturated zone, but also because the water then occupies less of the volume of soil from which evapotranspiration takes place.
Name two types of proteins that regulate the cell cycle. How do these proteins work?
Answers
Answer:
Internal and external regulators are two types of proteins that regulate the cell cycle. Internal regulators allow the cell cycle to proceed only after certain events occur. External regulators speed up or slow down the cell cycle.
Explanation:
I hope this helps :)
The two types of proteins that regulate the cell cycle are Cyclins and Cyclin-dependent Kinases (CDKs). These two groups of proteins are responsible for the progress of the cell through various checkpoints.
What are Proteins?
Proteins are made up of hundreds or thousands of smaller units called Amino acids. They are large, complex molecules that play many critical roles in the body. They do most of the work in cells and are required for the structure, function, and regulation of the body’s tissues and organs.
Cyclins regulate the cell cycle only when they are bound to Cdks and become fully active. The Cdk/cyclin complex must be phosphorylated, which further initiates other proteins to be phosphorylated that advances the cell cycle.
Retinoblastoma (Rb), is another group of tumor-suppressor proteins that regulates the cell cycle by monitoring the cell size.
Therefore, there are two types of proteins that regulate the process of the cell cycle are Cyclins and Cyclin-dependent Kinases (CDKs).

mechanical waves?
A. They must travel through a medium, such as
the bedrock of the Earth.
B. They will only travel through empty space.
C. They travel in circles.
D. They do not require a medium.
Answers
Answer:
The correct answer is - option A.
Explanation:
The seismic waves are the waves that are the result of an explosion or the breaking of the rock within the earth. In other words, when these explosions or breaking cause an energy transfer within the earth are seismic waves. Seismic waves require a medium to travel and normally it is the earth.
The bedrock of earth is a great example of a medium for traveling these waves that make it a mechanical wave. Earthquake is the result of such waves.
