Answer:

Mitosis and meiosis are different types of cell division, and although they are first ... One could be forgiven for the assumption that the classic 'onion root tip squash' ... magnification using the eyepiece and objective lens, you will need to be able to ... about how the cells were being used, and had been given no explanation, ...

Explanation:

Answer 2

The cells of the ONION ROOT TIP undergo cytokinesis. This process is evidenced under the microscope by the formation of the CELL PLATE between two daughter cells.

Mitosis is a type of somatic cell division that has four main steps (prophase, metaphase, telophase and anaphase) followed by cytokinesis.

Moreover, cytokinesis is the division of the cytoplasm to form two daughter cells.

The cell plate is a transient compartment that grows between daughter cells. Once cytokinesis is completed, the cell plate gives rise to the cell wall.

In conclusion, the cells of the ONION ROOT TIP undergo cytokinesis. This process is evidenced under the microscope by the formation of the CELL PLATE between two daughter cells.

A plant produces seed cones and pollen cones . Is it vascular? To what group of plants does it belong

Answers

A plant produces seed cones and pollen cones. Belong to plant group
phylum Coniferophyta and Yes it is vascular

A plant that produces seed cones and pollen cones is a vascular plant, and plants that produce seed cones and pollen cones belong to the group of plants known as gymnosperms.

What are gymnosperms?

Gymnosperms are a group of seed plants that produce seeds that are not enclosed in an ovary and produce open seeds that are usually borne in cones and include a variety of plant species, including conifers such as pine, spruce, and fir trees, cycads such as palm-like plants, ginkgoes, etc., and the production of seed cones and pollen cones is a vital characteristic of gymnosperms, these seed cones, which are also called female cones, produce seeds that are typically larger and more complex than pollen grains.

Hence, a plant that produces seed cones and pollen cones is a vascular plant and belongs to the group of plants known as gymnosperms.

What is standard deviation?

The standard deviation in statistics is a measurement of how much a group of data may vary or be dispersed. While a high standard deviation suggests that the values are dispersed throughout a larger range, a low standard deviation suggests that the values tend to be near to the established mean.

An average is one number chosen to represent a group of numbers; it is often the sum of the numbers divided by the number of numbers in the group. The average of the integers 2, 3, 4, 7, and 9 is, for instance, 5.

15. Explain how each of the following creates electrical energy:
a.
Solar
Hydro
Tidal
Wind
OTEC
Biomass
Geothermal

Answers

Solar- technologies convert sunlight into electrical energy either through photovoltaic panels or through mirrors that concentrate solar radiation.

Hydro- a hydraulic turbine converts the energy of flowing water into mechanical energy. A hydroelectric generator converts this mechanical energy into electricity

Tidal- energy is a form of hydropower that works by harnessing the kinetic energy created from the rise and fall of ocean tides and currents, also called tidal flows, and turns into unusable electricity

Wind- turns the propeller like blades of a turbine around a rotor, which spins a generator, which creates electricity

OTEC- plants pump large quantities of deep cold seawater and surface seawater to run a power cycle and produce electricity

Biomass- is burned in a boiler to produce high-pressure steam. This steam flows over a series of turbine blades, causing them to rotate. The rotation of the turbine drives a generator, producing electricity

Geothermal- power plants use steam to produce electricity. The steam comes from reservoirs of hot water found a few miles or more below the earth’s surface. The steam rotates a turbine that activates a generator, which produces electricity

9. If the concentration of water inside a cell is lower then outside the cell, what will be the net
movement of water molecules be? *
(1 Point)
a) Into the cell.
b) Out of the cell.

Answers

Answer:

a) Into the cell.

Explanation:

The water molecules outside the cell would move into the cell until there is no net movement of water molecules. This process is known as osmosis.

Osmosis is the movement of molecules from a region of higher concentration to a region of lower concentration through a semi-permeable membrane until the concentrations across the membrane are equal. That is, there is no net movement of molecules across the membrane.

How does the attachment of spindle fibers differ between mitosis and meiosis I?

Answers

in mitosis, the spindle fibers start to divide. in meiosis, these fibers match back up again

In mitosis, the spindle fibers from two poles attach to each chromosome but in meiosis I, the spindle fibers from only ONE pole attaches to the chromosome.

WHAT IS MITOSIS AND MEIOSIS?

Mitosis and meiosis are two kinds of cell divisions. Mitosis involves separation of a single parent cell to produce two genetically identical cells while meiosis involves the separation of a single parent cell to produce four genetically different daughter cells.

WHAT IS SPINDLE FIBER?

Spindle fibers are structures that emanate from centrosome organelles and responsible for the separation of chromosomes during karyokinesis (nuclear division).

During the two cellular divisions (mitosis and meiosis), spindle fibers attach to the centromeres of each chromosome in order to align and eventually divide them.

However, in mitosis, spindle fibers from two opposite poles attach to each chromosome but in meiosis I, the spindle fibers from only ONE pole attaches to the chromosome.
