Answer and Explanation:
The Hooke microscope was designed by the famous British scientist in the 1600s. Robert Hooke only design the microscope; actually, the microscope was made by instrument maker.
Robert Hooke's design improved microscope illumination and mechanism, which enhance the magnification to 50X and improved resolution.
Robert Hooke was the first man who coins the name cell after observing angular spaces that saw in a thin cork section. He used a compound microscope to observe the pores in the cork.The Hooke microscope and telescope have some common features, such as a socket and ball joint for disposing of the body, separate draw tubes and an eyecup to retain the correct distance between eyepiece and eye. The microscope body tube was made of wood. Hooke used a bi-convex objective lens, tube lens and two additional lenses. The resolution limit of the microscope depends on how well a lens focus light. We do not know we have exact information about the resolution of the Hooke microscope. However, by using the magnification power of the instrument, we can estimate the resolution limit. Hooke microscope has 30X magnification power.
The limit of resolution of Hooke's microscope was 8.3 μm.
The Hooke's microscope was developed by the scientist Robert Hooke in the late 1600s in order to observe cellular structures.Hooke's microscope consisted of a bi-convex objective lens and two additional lenses.The resolution of Hooke's microscope was 8.3 micrometers (μm), where 1 μm is equal to 1×10−⁶ m.In conclusion, the limit of resolution of Hooke's microscope was 8.3 μm.

How did the Everglades wetlands become drier?
More water was used to irrigate out-of-state farms than could be replenished by rainfall
Dam and canal building forced water into underground aquifers to expose wetlands
Climate change caused water in the Everglades to evaporate
Dam and canal building diverted the historical flow of water away from the Everglades.
Answer:
The correct answer is - Dam and canal building diverted the historical flow of water away from the Everglades.
Explanation:
To settle Florida the early settlers wanted to drain the everglades, they wanted to create agricultural land for farming by digging canals and building a dam to divert the flow of water of historical everglades.
They make and diverted the dam and big canals to flow the ocean and clear swamp waters of the everglades. Which made the everglades drier.
Consider the models of cell reproduction. Evaluate the statements and select ALL that are NOT supported by the models.
Answer and Explanation:
The cell division cycle is responsible for increasing and maintaining cell number and size. This cycle is an essential feature of living organisms. There are four phases of cell division mitotic phase (M phase), growth phase 1 (G1), growth phase 2 (G2), and synthesis phase (S). One phase of the cell cycle ends, and the other starts; this is named a phase transition—a unidirectional alteration in the cell cycle phases. During G1, G2, and S phase cell grows and during the M phase cell divides. There are two models of cell reproduction as the clock model and the domino model. The domino model implies that cell division phases must occur in a distinct order and at a definite time. The domino model recommends that the cell cycle events are independent, while the clock model shows that the effectiveness of mitosis entrance was not persuaded by other actions.
Answer:
E. Meiosis and mitosis both result in cells with half the genetic information of the parent cell.

in an earthquake?
A. fracture
B. plastic
C. shear stress
D. elastic
Answer:
a. fracture deformation
A fault is a crack or region of cracks that separates two rock blocks. The blocks might move in relation to one another due to flaws. This movement may happen suddenly, like an earthquake, or it may happen gradually, like a creep. Thus, option A is correct.
What is fracture deformation in earthquake?Simply said, fractures are places in the crust's crust where there is no movement. According to the relative movement that occurs along a fault, faults are categorized.
Strong evidence supports the fracture hypothesis of earthquakes, given the close resemblance between earthquakes and fractures.
Earthquake occurrence stochastically, the relationship between earthquake size and frequency, and the mechanism underlying different earthquake sequence patterns.
Therefore, Deformation results from plate tectonic forces and gravitational forces.

1. Plants living in water absorb minerals from the water around them. What adaptations do land-dwelling plants have
that allow them to absorb minerals?
O Land-dwelling plants have developed vascular tissue in order to transport water and nutrients from the soil to the structures of
the plant.
Land-dwelling plants have developed chloroplasts in order to use minerals during photosynthesis.
Land-dwelling plants have developed a woody tissue layer to transport water and nutrients up and down the plant.
>
O Land-dwelling plants developed stomata in order to absorb minerals from the soil.
Answer:
O Land-dwelling plants have developed vascular tissue in order to transport water and nutrients from the soil to the structures of the plant.
Explanation:
Plants that live in water called AQUATIC plants, are structurally adapted to the water environment. One of these adaptations is that they have the ability to absorb minerals needed for their growth and development from the water around them.
However, land-dwelling or terrestrial plants also possess this ability to absorb minerals, however, they have a different adaptation from the aquatic or water-dwelling plants. Land-dwelling plants have developed vascular tissue (xylem, phloem) in order to transport water and nutrients from the soil to the structures of the plant.

Electromagnetic radiation is energy that travels in waves. Some examples of electromagnetic radiation are visible light, radio waves, and x-rays. Which statement is true for all forms of electromagnetic radiation?
Answer:
They all travel with the speed of light.
Note: No options were provided in the question.
Explanation:
Electromagnetic radiation are a group of waves which are are produced by the vibrations of electromagnetic fields. Electromagnetic waves/radiation possess the ability to travel through vacuum (i.e. they do not require a material medium for their propagation) while also carrying radiant energy. Electromagnetic fields which are the sources of electromagnetic radiation, exist as a result of the combination and interaction of travelling electric and magnetic field forces.
Electromagnetic radiations consists of the following waves: radio waves, infrared waves, visible light, ultraviolet rays, X-rays, and gamma rays. These waves have differing and unique properties such as wavelength, frequencies, ionizing properties, penetrating ability, sources as well as well as uses. However, they have a common property of velocity- they travel with the speed of light, 3.0 * 10⁸ m/s.
In addition to having the same velocity, all electromagnetic radiation exhibit interference and diffraction.

Which action would most likely increase the greenhouse effect?
Answer:
The correct answer is - B. burn more oil for heating homes.
Explanation:
Burning oil or fuels produce a high level of carbon dioxide which is a greenhouse gas and result in store in the atmosphere and does increase the temperature of the earth and increase the greenhouse effect. Nuclear power does not affect greenhouse gasses as it releases carbon dioxide same as a wind power plant.
The other two option helps in lowering the effect of the greenhouse effect on atmosphere or help in lower the greenhouse emmission.

Scientists can “edit” sequences of DNA by locating and replacing certain nucleotides. Explain how and why these edits will have consequences on the resulting trait.
Answer:
Gene editing can be used to modify DNA sequences at target genes, thereby regulating proteins encoded by them
Explanation:
Gene editing refers to the methodologies used in molecular genetics to discretionally modify the DNA sequence of targeted cells. Since genes control phenotypic features by specifying the synthesis of specific proteins, these methodologies have the potential to alter specific traits. Recently, a gene-editing methodology called CRISPR-Cas9 has emerged as a versatile programmable gene-editing system which can be used to easily change the DNA both in-vitro and in vivo. This gene-editing system has been adapted from a naturally occurring genome engineering system existent in bacteria.
