Shawna is writing a paper for her science class, and she wants to include a list of luminous objects. These are objects that produce and emit
their own light. Objects that are not luminous, also called illuminated objects, only reflect light.
Which list should Shawna add to her paper?

Answers

Answer 1

Answer:

The sun, the star Proxima Centauri, and the star Polaris.

Explanation:

The sun and stars emit light on their own, therefore they are luminous.

All members of a population share the characteristic of belonging to the same species. Therefore, the correct option is C.

What is a population?

A population is defined as a group of organisms of the same species that live in the same geographic area and are able to interbreed with one another. This means that they share many common traits and characteristics, such as physical appearance, behavior, and genetic makeup.

Option a (temporal isolation) and option b (geographic isolation) are not the characteristics that all members of a population share.

Option d (identical genes) is also not correct, as members of a population may have genetic variation due to mutations, genetic recombination, and other factors. Therefore, the correct option is C.

Explanation:

Javier investigated what happens when Earth's plates meet. He found that as Earth's plates meet at plate boundaries and interact, they move in three different ways. The ways they interact produce changes on land and on the ocean floor. What are the kinds of boundaries that plates form? Label each plate boundary with the correct type from the choices below.

Answers

Answer:

I. Divergent

II. Convergent

III. Transforming

Explanation:  

The crust is the outermost layer of the earth. It is divided into many plates that move over the mantle. Nowadays, there are six different bigger plates and twelve that are smaller. These plates are limited by three types of ridges or borders that differ in the movement they produce.

Boundaries types:

I. Divergent: New crust is created by the rising molten materials coming from the mantle. Two plates separate, and the stream of hot material creates a new seabed between them. It occurs an expansion of the sea bottom. As old plates get separated, the new and young crust instantaneously gets formed. The emerging mantle occupies the space left by the separation of the two plates. This process occurs along with an underwater mountain range, known as the mid-oceanic ridge or divergent ridge. An example of this is the ridge located in the middle of the Atlantic Ocean, extending from Greenlander to the southernmost point of South America.

II. Convergent. Collision area between two plates. Two oceanic plates might collide, or one oceanic plate with a continental one. In this last case, the oceanic crust sinks under the continental plate, and magma rises to the surface by crevices. The thicker and older plate subduces under the other plate. The Himalayas and Los Andes are examples of these collisions. Also, collisions create volcanic arches and continental arches.

III. Transforming. The plates slide laterally with each other, and they are usually called faults. It is associated, in general, with the oceanic ridge, although it might also occur in the continental plate. No rocky material is either destroyed or formed. When the plates move and produce a displacement of one transforming limits from side to side, earthquakes occur. The movement breaks the crust and originates pronounced fractures. The San Andrés fault is an example of this plate ridges.

The kinds of boundaries that plates form is the fact that seismic activity takes place at the three known types of plate boundaries called divergent, convergent, and transform.

What happens when Earth's plates meet?If two tectonic plates meet, they create a kind of convergent plate boundary.

One converging plates often shift or move below the other, in  an act known as subduction.

The new magma (molten rock) tend to increase and may erupt to create volcanoes.

Photosynthesis is a process almost every plant goes through. The goal of the process is the create glucose, a sugar that can be turned into energy. Photosynthesis consists of 2 cycles: light-dependent and light-independent (aka Calvin Cycle). Photosynthesis requires carbon dioxide, water, and sunlight. These reactants can then be transformed into glucose and oxygen. Photosynthesis is the basis of energy for all animals.

Your answer: Here are 3 reasons that go against growing wheat this way.

1. The fertilizers and pesticides are expensive and cost farmers a lot which takes away from the revenue that farmers make from growing the crops in the first place.

2. Other then fertilizers and Pesticides its a lot of work as you can see on the chart throughout the year there are many things you must do too keep crops bug free and pest free this reason I'm explaining says that taking and doing all of this work for not pests/bugs is too much and not needed.

3. Fungicide Is needed a lot and incredibly expensive when you used/spray it on crops that much and point goes a lot more for large crops too.

If these reasons don't work, find factors that or counterclaims that go against this method of harvesting wheat. (This is what your supposed too do)

What is photosynthesis ?

Green plants and certain other organisms convert light energy into chemical energy through a process called photosynthesis. Light energy is gathered and utilised during photosynthesis in green plants to change water, carbon dioxide, and minerals into oxygen- and energy-rich organic molecules.

The first method of breaking down glucose to release free energy is called glycolysis .Two molecules of pyruvate, two molecules of ATP, two molecules of NADH, and two molecules of water are produced during glycolysis.
