The Crawfish is 400 times larger than the human oocyte.
How to calculate the area?It should be noted that the radius is given as 1mm.
The surface area is also illustrated as 4πr². The surface area will then be:
= 4 × 3.14 × (1)²
= 4 × 3.14 × 1
= 12.56mm²
The radius of human = 0.05m
The surface area is also illustrated as 4πr². The surface area will then be:
= 4 × 3.14 × (0.05)²
= 4 × 3.14 × 0.0025
= 0.0314mm²
The ratio will be:
= Crawfish / Human
= 12.56 / 0.0314
= 400
In conclusion, the crawfish is 400 times larger than the human oocyte.

A sledgehammer has a mass of 3.5 kilograms. What net force, to the nearest whole newton, will a person need to apply to accelerate the sledgehammer at a rate of 4.0(m)/(s^(2)) ?
Record your answer in the boxes below. Be sure to use the correct place value.
Force is equal to mass multiplies with the acceleration.
So, the correct answer is 14 N.
What is Force?Force is the push or pull of an object which cause changes in velocity or to accelerate with mass. It is a vector quantity which means it has direction as well as magnitude.
A force is usually denoted by the symbol F. Below equation is derived from the second Law of Newton.
F = m·a
where F = force, m = mass, and a = acceleration.
For above example,
Mass= 3.5 kg
Acceleration (a)= 4[tex]m/s^{2}[/tex]
so, F=3.5*4= 14N
The SI unit of force is the Newton (N). Other units of force include dyne, kilogram-force (kilopond), poundal and pound-force.
Thus, Force is equal to mass multiplies with the acceleration.
So, the correct answer is 14 N.

Gregor Mendel's observation of pea plants that were either round or wrinkled, yellow or green, gave rise to the concept of a dihybrid cross.When two heterozygous people are crossed, the offspring's genotype and phenotypic ratios will be predictable. Crossing heterozygous parents would result in an estimated phenotypic ratio of 9:3:3:1.Deviations from these predicted ratios may point to a relationship between the two features or to a non-Mendelian method of inheritance for one or both of the traits.The genotypes of a specific cross or breeding experiment are predicted using the Punnett square, a square diagram.16 different genotypes will be formed.

Which phase of the cell cycle begins after G₁ phase is complete?
A. Cytokinesis
OB. G2 phase
OC. M phase
OD. S phase
The S Phase takes place after when G1 phase is completed.
The cell cycle generally composed of four phase that are G1, S, G2 and M (Mitotic phase) G1, S, G2 phases are the part of interphase.
A cell divides Into two daughter cells as a result of a sequence of events known as the cell cycle, or cell-division cycle. These occurrences include the duplication of its DNA and a few of its organelles, followed by the cell division process, which involves dividing the cytoplasm and other parts of the parent cell into two daughter cells.
DNA synthesis or replication takes place during the S phase of a cell cycle, which happens during interphase and comes before mitosis or meiosis. By doing this, a cell’s genetic material doubles before it begins mitosis or meiosis, providing enough DNA for the cell to divide into daughter cells. Only once the cell has grown sufficiently to contain twice as much DNA and has crossed the G1 checkpoint does the S phase start. Until this occurs, p16, a protein, stops S phase.

Human transportation enabled a species of beetle to move from Asia to
North America. This beetle feeds on a particular species of flowering
trees. In its native habitat, predators control its population. However, the
beetle has fewer predators in North America.
What kind of organism is this beetle, in the new ecosystem? What would
its effect be on flowering trees?
The first instances of an exotic long-horned beetle destroying ornamental trees were in Chicago and New York City. Since then, beginning in 1996, reports of this pest have been made throughout the majority of the northeastern states as well as in California. Native to Asia, the Asian Long-Horned Beetle (ALB) decimates a wide variety of tree species, including poplars, maples, elms, and mulberries. Large and noticeable, these beetles can be easily identified by their horns or antennae. This insect harms the ecosystem around people by destroying priceless park and shade trees as well as damaging or even destroying forest trees with high economic worth (e.g., sugar maples in the northeast USA). Physical hazard from falling branches or trees during wind and/or ice storms is also posed to people and vehicles by the structural weakness of trees caused by tunneling larvae.

All living things require energy to carry out their activities. Metabolism is a series of chemical events that provide energy for cellular operations. Every movement or action performed by an organism consumes energy.
Why do organisms need energy?
Role of energy:
By reading a book, walking or running. Your body needs energy all the time. There are activities in our bodies that we are not even aware of that require energy.
For example, our heart keeps beating and breathing. We digest food, absorb it into our bloodstream and carry out various activities in our body. Therefore, all these processes, like many others that occur in the body, require the use of energy.
How do organisms use energy?
Almost everything consumes sunlight or anything that consumes sunlight. The sun is the primary source of energy for species and the environments in which they live. For example, plants and algae use the energy of sunlight to create food energy by mixing carbon dioxide with water. Additionally, this process initiates the transfer of energy through virtually all food webs.
