Answer:
Cytology is the study of cells as fundamental units of living things.
3. What is the purpose of mitosis?
A. To produce haploid cells.
B. To produce diploid cells,
C. To produce half the number of cells,
D. To complete cellular respiration.
Justify
Answer:
B.) To produce diploid cells
Explanation:
The answer is B because mitosis works by duplicating each chromosome and dividing the copies evenly across the two sides of the cell. As a result, when a cell divides down the middle, each new cell receives its own copy of each chromosome, therefore producing diploid cells.

Using the DNA sequence below, what would the resulting amino acid sequence be? Be sure to show any necessary steps that lead you to the amino acid sequence from the DNA sequence.
TAC-GGC-ATA-TCG
Answer:
Notice that many amino acids are represented in the table by more than one codon. For instance, there are six different ways to "write" leucine in the language of mRNA (see if you can find all six).An important point about the genetic code is that it's universal. That is, with minor exceptions, virtually all species (from bacteria to you!) use the genetic code shown above for protein synthesis.

The atoms that undergo nuclear fusion become smaller
True
False
Answer:
True
Explanation:
In nuclear fission, an unstable atom separates into two or more shorter, more steady fragments, discharging energy. Matter is not preserved throughout this process because some of the weight of the merging nucleus is transformed to power, which would be discharged. Fusion is the mechanism through which massive stars generate enormous energy amounts.

for this assignment your teacher will give you an egg and some building materials. You will use these materials to build a device that will keep an egg from cracking when it is dropped from a certain height. Then you will test the device determine how well it worked and make recommendations to improve its design. You will present your final design and logic that supports it in a lab report. Your lab report must include the title and initial design, observations from your experimental tests and recommendations for a final design based on force and momentum concept. as well as observations from the test conducted. To help you write your lab report there is a student worksheet on the last few pages of this document.

In order to reduce the reactionary force due to the momentum of the egg, the device should be built with soft materials to be effective.
What is force and momentum?A force is an agent which acts to distort the shape or change the motion of a moving object or the state of rest of a stationary object.
Momentum is the product of the mass of the a body and it's velocity.
Based in Newtons law of motion, a cushioning device for an egg can be construct such that the momentum of the egg is spread out over the surface of the cushioning material.
Therefore, the device should be built with soft materials to be effective.

[FW.02]The Karst topography in Florida is formed as a result of the actions of
O geysers
O groundwater
O recharge
O hot springs
The Karst topography is the geographical feature formed from the deposition of soluble rocks. It was also formed as the result of the action of the groundwater. Thus, option B is correct.
What is Karst's topography?Karst topography is the geographical structure formed by the solution and soluble rocks like dolomite, limestone, and gypsum. They also have underground caves and drainage systems.
The action and the force of the groundwater or the surface water are the main reason behind the formation of these topographical structures. They were used as a place for water storage and supported clean drinking water.
Therefore, the Karst topography in Florida was formed due to the action of the groundwater.

A cloud directly above you is about 10° across. From the weather report, you know that the cloud is at an altitude of 2200 m. How wide is the cloud?
The width of the cloud is : 384 m
Given data :
Cloud altitude = 2200 m
Temperature = 10°
Determine how wide the cloud isapplying the equation below
I = d[tex](\frac{\alpha }{57.3})[/tex]
where : I = linear size , d = 2200 m , [tex]\alpha = 10^{o}[/tex]
therefore :
I = 2200 ( 10 / 57.3 )
= 383.94 m
≈ 384 m
Hence we can conclude that the width of the cloud is : 384 m

What is Ecosystem?An ecosystem is a region where a bubble of life is created by plants, animals, and other organisms interacting with the weather, environment, and other factors.
Abiotic variables, or nonliving components, coexist with biotic components in ecosystems. Plants, animals, and other species are biotic factors.
Every component of an ecosystem is directly or indirectly dependent upon every other component. An ecosystem's temperature changes frequently have an impact on the types of plants that may flourish there, for example.
