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

When heat is introduced to matter, what happens to the matter at the molecular level?
Explain in science
Answer:
When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The motion and spacing of the particles determines the state of matter of the substance. The end result of increased molecular motion is that the object expands and takes up more space.

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.
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?
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.

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.
