The four options that accurately describe reproduction in gymnosperms are:Fertilized ovules grow into seeds.Male and female cones may grow on the same plant.Most gymnosperms produce male and female cones.Some require heat for seed dispersal.Female cones do not produce pollen in gymnosperms. Instead, male cones produce pollen which is then carried by the wind or insects to the female cones for fertilization.

Jean listed the steps involved in the life cycle of a gymnosperm.
1 - The pollen gets stuck in a sticky liquid.
2 - Sperm from the pollen fertilize the egg in the ovule.
3 - The ovule develops into a seed.
4 - When mature, the seeds are dispersed.
Which step is missing?
Before step 3, the ovule develops cones.
Just after step 3, the ovule develops cones.
Before step 1, wind carries pollen from the male to the female cones.
Just after step 1, wind carries pollen from the male to the female cones.
Answer:
I don't believe there is a missing step in the listed sequence provided by Jean. However, it’s worth noting that gymnosperms typically produce cones (also called strobili) that contain the reproductive structures, rather than the ovules developing into cones. The cones can be either male or female and are responsible for the production and dispersal of pollen or seeds, depending on the species. Therefore, the development of cones should be included in the life cycle of a gymnosperm, but it does not necessarily occur just before or after a specific step in the sequence listed by Jean.
Hope I could help.
Which type of gymnosperm has the least amount of species diversity on Earth today?

Which material should the engineer choose if he wants the filling design to be durable and attach to the natural tooth?
A. composite
B. silver
C. gold
D. porcelain
A. Composite is the material that the engineer should choose if he wants the filling design to be durable and attach to the natural tooth. Composite is a tooth-colored material made of plastic and glass that is used to fill cavities and repair other dental damage. It is a durable and strong material that can bond well with the natural tooth, providing a natural appearance and long-lasting results. Silver, gold, and porcelain are also commonly used dental filling materials, but they may not bond as well to the natural tooth or offer the same level of durability and strength as composite.
Which characteristic do ginkgoes and cycads have in common?
are usually evergreen
lived during the time of dinosaurs
produce football-sized cones
have a shallow root system
Answer: The characteristic that ginkgoes and cycads have in common is that they lived during the time of dinosaurs.
Explanation: The characteristic that ginkgoes and cycads have in common is that they lived during the time of dinosaurs. Ginkgoes and cycads are both ancient plants that have been around since the time of the dinosaurs, and have survived through millennia of changes in climate and ecological conditions. While both plants have unique features, their ancient lineage is the common characteristic between them.
Option B is correct. Both, ginkgoes and cicadas are types of plants that existed during the time of dinosaurs.
Ginkgoes, especially The Ginkgo biloba species are living fossils as they can still be found in various parts of the world, particularly in China even though they coexisted with dinosaurs.
During the time of dinosaurs, cycads were quite diverse and widespread, and they thrived alongside dinosaurs. They have a palm-like or fern-like structure.

The diagram above shows the repeating groups of atoms that make up two samples. Both samples are liquid at room temperature. Will the properties of the two samples likely be the same or different? (Examples of properties are smell, color, and the temperature at which a substance melts.)
Answer:
Different.
Explanation:
If you look at the bottom you can see that the bonds are in different cohesions and the molecules have a quad bond and not a tri bond. Atoms defuse ( the process in this photo is diffusion) and the smell, color, and temperature will change.
Ian drew a diagram to compare conifers and cycads.
Which characteristic belongs in the area marked Z?
are the largest group
produce cones
look like palm trees
may grow in cold climates
Answer:
Even though you did not provide "Z" this is the basic answer.
Conifers Cycads Z (I think this is what you mean)
Produce cones Look like palm trees May grow in cold climate
Are the largest group (group of what)
Explanation:
If you would have explained what "Z" is than the answer could have been more concise. By any chance if "Z" does not mean similarities than you could put the "May grow in cold" in conifers.

A company sells a natural medicine with plant ingredients to help treat dementia, a disease in which people have a hard time remembering things.
The natural ingredients in the medicine are most likely from which type of plant?
gnetophyte
conifer
ginkgo
cycad
Answer:
The natural ingredients in medicine are most likely from a variety of plants, including but not limited to gnetophytes, conifers, ginkgo, and cycads. However, the specific plants used for medicinal purposes depend on the type of medicine and its intended effects. For example, aspirin, a widely used pain reliever, is derived from the bark of the willow tree (Salix spp.), while the cancer drug Taxol is extracted from the bark of the Pacific yew tree (Taxus brevifolia). So, it's not possible to narrow it down to a single type of plant.

How do you think plants would grow in space? Which tropism(s) would be affected and why?
Answer: Mainly gravitropism because of the lack of gravity. The other two tropisms depend on the circumstance that it is in.
Explanation:
Answer: Plants use other environmental factors, such as light, to orient and guide growth
Explanation: In the absence of gravity, plants use other environmental factors, such as light, to orient and guide growth. A bank of light-emitting diodes (LEDs) above the plants produces a spectrum of light suited for the plants' growth.
