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.

Answers

Answer 1

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.

Answer 2

The missing step is Before step 1, wind carries pollen from the male to the female cones.

The life cycle of a gymnosperm begins with the production of pollen in male cones. The pollen is then carried by the wind to female cones, where it fertilizes the ovules. The ovules then develop into seeds, which are dispersed by the wind or animals.

The correct order of the steps is:

Wind carries pollen from the male to the female cones.
The pollen gets stuck in a sticky liquid.
Sperm from the pollen fertilize the egg in the ovule.
The ovule develops into a seed.
When mature, the seeds are dispersed.
So the answer is Before step 1, wind carries pollen from the male to the female cones.

Can someone please put these atoms from most reactive to least reactive? Thank You!

Answers

Argon is the least reactive because it is a noble gas. Sodium is more reactive than magnesium. Silicon is not very reactive but Argon is least. So Argon is the least, silicon is next, magnesium, and sodium is the most reactive.

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

Answers

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.

The answer is composite A

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

Answers

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.

Ginkgo is the type of gymnosperm that has the least amount of species diversity on Earth today. There is only one living species of Ginkgo, known as Ginkgo biloba, which is native to China and is commonly grown as an ornamental tree in many parts of the world. In contrast, there are over 600 species of conifers, which are the most diverse group of gymnosperms. Cycads and gnetophytes are also relatively diverse, with around 300 species of cycads and around 70 species of gnetophytes.

Different.

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.

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

Answers

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.

Explain how potential and/or kinetic energy are working in each of the pictures below

Answers

Answer: canetic carts

Explanation:

In the first one, kinetic energy got the roller coaster to the top of the hill, and it becomes lots of potential energy due to being at the top of a steep drop.

In the second one, it begins with potential energy, until the person is put into a falling motion, transferring to kinetic energy.

In the third one, there is potential energy, because the bow string is taut, and ready to release and allow the arrow to go flying.

In the fourth one, the car has gas which is potential energy, until it begins moving and is turned into kinetic energy.
