Answer:D I believe
Explanation:
Matter and energy both can neither be created or destroyed
True or false
Please explain thank you!
Answer:
true
Explanation:
Both the initial and final substances are composed of atoms because all matter is composed of atoms. According to the law of conservation of matter, matter is neither created nor destroyed, so we must have the same number and type of atoms after the chemical change as were present before the chemical change.
l. A farming area developed a major locust problem. Swarms of locusts were destroying crops and the environment. A team of
scientists developed an infectious disease that would reduce the population of locusts What would be most important to find
out before producing and releasing the disease?
how a decreased number of locusts would affect other organisms
which species might eat the crops in the absence of locusts
how the disease can be used for other applications
O how quickly farmers would get to see the results
Answer: how a decreased number of locusts would affect other organisms.
Explanation:
When engaging in any action aimed at destroying large numbers of an organism as is the case here, there is always a need to check what impact it might have on the ecosystem at large.
This is why it is very important that the effect of a decreased number of locusts on other organisms is evaluated before such drastic action is taken. If it would lead to a situation where the ecosystem is destabilized, the consequences would be far reaching and very damaging.
How a decreased number of locusts would affect other organisms is the
most important to find out before producing the disease.
What is Population?This is referred to the number of organisms present in an area over a
specific period of time.
We were told that swarms of locusts destroyed the environment and
needed to be reduced through the creation of a disease. The effect the
decrease in locust has on other organisms has to be considered to ensure
the ecosystem is balanced and doesn't adversely affect others.

Answer:
Some of them lose their leaves in the winter, they are the oldest type of seed plant, and they include the tallest type of seed plants
Explanation:
Gymnosperms are those which grow small flowers, they are the oldest type of plant with seeds, and female cones that produce pollen. So, the correct options are C, D and F.
What are Gymnosperms?Gymnosperms are defined as vascular plants that reproduce by means of an exposed seed, or ovule, such as angiosperms, or flowering plants, whose seeds are surrounded by mature ovaries or fruits. The seeds of many gymnosperms are produced in cones and do not appear until maturity.
Gymnosperms are found in temperate forest and boreal forest biomes where the some common types of gymnosperms are conifers, cycads, ginkgoes, and gnetophytes.
Thus, Gymnosperms are those which grow small flowers, they are the oldest type of plant with seeds, and female cones that produce pollen. So, the correct options are C, D and F.

Explanation:
How do the nutrients found in plants function in plant DNA? Is the function of plant DNA similar to human DNA?
Answer:
How do the nutrients found in plants function in plant DNA?
Plants take up essential elements from the soil through their roots and from the air (mainly consisting of nitrogen and oxygen) through their leaves. Nutrient uptake in the soil is achieved by cation exchange, wherein root hairs pump hydrogen ions (H+) into the soil through proton pumps.
Is the function of plant DNA similar to human DNA?
How much DNA do plants share with humans? Over 99%? ALL animals and plants share the same DNA which is basically a code of only 4 'letters' which code for the same amino acids from which all proteins are made.

D) Matching glacier scraping patterns on the coasts of different contents.
Answer:
A)Ocean floor evidence of sea floor spreading.
Explanation:
evidence pointing to the steps or process of seafloor spreading and effective plate motion This theory was accepted by many scientist because it depended on hard evidence and could describe most of the modern geological structures such as ocean basins,
What is the tectonic theory?
The theory of plate tectonics plates says that Earth's surface is made of rigid slabs of rock, or plates, that move to each other.
What is a tectonic plate?
They are huge slabs of rock that cover the earths mantle When a earthquake occurs that's because the tectonic plate is breaking that makes the ground shake During the earthquake and afterward, the plates keep on shaking until they are stuck again!
Hope this helps!

The plate tectonic theory gave the concept of land and sea formation. "Ocean floor evidence of seafloor spreading" acted as evidence to support the plate theory. Thus, option A is correct.
What is plate tectonic theory?The plate tectonic theory states about the formation of the lithosphere by the movement of the plate tectonics located deep in the mantle and core layer of the earth. These plates show movement slides over each other to produce lands and drifts to form the oceans.
At a very early there was a supercontinent, Pangaea that slowly shows the formation of the current continent by the movement of the tectonic plates. These solid hard rocks of the earth layers allowed the formation of the various land formations.
The seafloor spreading is the best evidence that supports the tectonic plate theory that described the formation of the oceanic structures including the trenches and basins. The geological structures of the ocean floors supported the theory.
Therefore, option A. evidence of seafloor spreading supported the plate tectonic theory.

PLS DONT COPY AND PASTE THE ANSWER FROM THE INTERNET
The respiratory system and lungs work very closely with the cardiovascular system for the uptake and elimination of gases and the distribution of energy in the body.
How Oxygen from the air is absorbed?Oxygen from the air is absorbed into the bloodstream through the lungs. When it reaches the lungs, the function of the cardiovascular system begins, since that is where the non-oxygenated blood is oxygenated and returns to the heart.
When in the cardiovascular system, the blood reaches the capillaries in the tissues, oxygen is released, which the cells use to produce energy. These cells release waste products, such as carbon dioxide and water, which are absorbed and transported by the blood.
O2 and CO2 are constantly circulating and passing from one medium to another, so much so that O2 passes, along with other gases, from the atmosphere to the airways, entering through the nostrils and driving through the larynx, trachea, source bronchi, terminal bronchioles, respiratory bronchioles, alveolar sacs and alveoli.
Therefore, The respiratory system and lungs work very closely with the cardiovascular system for the uptake and elimination of gases and the distribution of energy in the body.
