Which category of gymnosperm is thought to have given rise to flower-bearing plants?
Select one:
a.
Cycadophyta
b.
ginkgophyta
c.
Coniferophyta
d.
gnetophyta
Answer:
d. Gnetophyta
Explanation:
Gymnosperms represent a group of "naked seed" plants which includes, among others, Cycads, Conifers and Gnetophytes. It has been proposed that Angiosperms or flowering plants, probably evolved from Gnetophyta about 150 million years ago. Gnetophyte is a group of Gymnosperms composed of only three living genera: Ephedra, Welwitschia and Gnetum. In Gnetum and Ephedra plants, researchers documented a regular process of double fertilization, which is a distinctive feature of Angiosperms. This important observation has been used to propose that Angiosperms evolved from Gnetophyta.
Answer:
Gnetophyta

Body systems interact with one another to carry out life processes. When we eat food, it is broken down into nutrients that can then be used by body cells for metabolic processes and building cellular structures. Many body systems are involved in this process. Select the body systems that would NOT be involved in the breakdown and utilization of nutrients.
Answer:
it says select so what are the options?

Investigation of HOX genes indicates that the animal family tree" can be simplified to only how many different types of animals?
Answer:
three evolutionary lines
Explanation:
The Hox genes are master developmental genes found in animals, which are involved in the regulation of development by specifying the body plan of an embryo along the head-tail axis. Recently, several research groups studied the assortment of the Hox genes in three different marine organisms: 1- a priapulid worm (an unsegmented marine worm), 2- a brachiopod (phylum Brachiopoda), and 3- a polychaete worm (related to earthworms). Then, these research groups combined their research efforts to compare the assortment of the Hox genes observed in these species to those observed in previously studied animals including, among others, mice, fruit flies and sea urchins. From this combined study, researchers concluded that the animal kingdom can be divided into three primary evolutionary lineages.

Jorge is drawing an atomic model. The part of the atom that he has drawn is shown below. What does Jorge need to add to complete his atomic model?
Answer:
An atom is the smallest particle in a chemical element that holds its chemical properties. Although in the past it was thought impossible to break an atom, within modern chemistry we know that an atom is composed of subatomic particles, which compose the atomic model:
1) electrons, which have a negative charge, such a small size that it is immeasurable, and a mass much smaller than the other two subatomic particles; 2) protons, which have a positive charge; and 3) neutrons, which have no charge.
The protons and neutrons form a dense and massive atomic nucleus, which is called multipons nuclei. The electrons form a cloud of electrons that surround the nucleus.
As a student jumps over a hurdle, she loses contact with the ground and moves upward. She returns to the ground because unbalanced forces cause a change in the — A mass of the student B height of the student’s jump C gravitational pull on the student D speed and direction of the student
Answer:
I need the picture or the numbers for it
Answer:
I believe its D speed and direction of the student
Explanation:
Unbalanced forces change an objects motion called acceleration
Acceleration is the change in speed or direction of an object

What is denaturation? What are some things that can cause this to happen?
Answer:
If a protein loses its shape, it ceases to perform that function. The process that causes a protein to lose its shape is known as denaturation. Denaturation is usually caused by external stress on the protein, such as solvents, inorganic salts, exposure to acids or bases, and heat.
hope this helps!!:)

Question 64 options:
Erosion
Plate tectonics
Earthquake
Subduction
Weathering
Volcano
Continental drift
1.
This is the movement of soil, mud and rock due to the downward movement of wind, water or ice.
2.
This is a landform that is formed by the eruption of magma through a vent from the interior of the Earth.
3.
This is a geologic even that occurs when tectonic plates are displaced violently.
4.
This is the geologic theory where the cooler surface of the Earth move slowly over the hotter layer underneath.
5.
This is the movement of Earth's continents, relative to each other, due to plate tectonics. Wegener stated that Earth's continents were once joined in a supercontinent, Pangaea, and broke apart about 200 million years ago and slowly moved to the present locations.

Where do North Carolina's River basins eventually flow into?
Gulf of Mexico and the Atlantic Ocean
Atlantic Ocean and the Great Lakes
O O O O
Gulf of Mexico and the Pacific Ocean
O Pacific Ocean and the Great Lakes
Answer:
Gulf of Mexico and the Atlantic Ocean
Explanation:
In North Carolina, there are total seventeen basins. Five basins are present in western region that drains to the Gulf of Mexico and the other river basins drains to the Atlantic Ocean.
11 of the river basins out of total 17 river basins originates in North Carolina and only four basins flow entirely within the state and rest drains to Gulf of Mexico and the Atlantic Ocean.
Hence, the correct option is "Gulf of Mexico and the Atlantic Ocean".

By the 1950s, there was Choose... major variety(ies) of banana being grown commercially in the world. Then, a soil fungus called Fusarium struck the banana plants, causing Panama Disease. Because of Choose... , the bananas could not resist the fungus. Within a few years, the entire commercial banana industry had collapsed. The industry switched to a different kind of banana. Yet fifty years later, Panama Disease has returned, and there is still no cure for it. Scientists argue that the best solution for the future is Choose... .
Answer:
Produce resistance variety or use of fungicides.
Explanation:
The best solution for the future is to produce resistance variety to Panama Disease or fungicide spray that kills Fusarium fungus that causes Panama Disease. If the variety is resistance against Fusarium fungus so they get no adverse affect from it. The use of chemical that kills Fusarium fungus is also a good method to protect banana industry from the adverse effect of this disease.
