how are humans are impacting the ecosystems of the United States? Give at least 3 different specific instances of humans are negatively impacted our oceans, lakes, rivers or aquifers.
Answer:
pollution, factories and lack of recycling
Explanation:
Pollution from nuclear waste plants run off into streams, lakes oceans, and etc. Factory's produce carbon monoxide and it gets trapped in streams, lakes, and oceans. Lack of recycling or throwing trash into the lakes, rivers and streams cause the animals inside to either get hurt, trapped, stuck, or die because of these pollutants.

mutation. What is another
name for this type of
mutation?
A. silent
B. point
C. deletion
D. inversion
Answer:
B. Point
Explanation:
Another name for this type of mutation is point mutation.
What is Point mutation?Point mutation is a type of genetic mutation that involves the alteration of a single nucleotide in the DNA sequence. This can lead to a change in the amino acid sequence of a protein, or it can result in a silent mutation that does not affect the protein's function. Point mutations can be classified into three main categories: transitions, transversions, and frameshift mutations.
Transitions involve the substitution of one purine for another purine, or one pyrimidine for another pyrimidine. Transversions involve the substitution of a purine for a pyrimidine, or vice versa. Frameshift mutations involve the insertion or deletion of one or more nucleotides, which shifts the reading frame of the genetic code and leads to a change in the amino acid sequence of the protein.

what is the first element with an atomic mass greater than 100
The first element with an atomic mass greater than 100 is Ruthenium (Ru).
Atomic mass refers to the mass of a single atom, the quantity of matter contained in the atom. In other words, atomic mass is the average mass of the atoms of an element.
To get the mass of an atom, the formula is mass number = protons + neutrons. Atomic mass is measured in atomic mass unit/ amu. Now, the element with an atomic mass nearest to 100 is Technetium (Tc), with an atomic number of 43 and atomic mass of 98. The element next to Tc is Ruthenium, atomic number 44 with an atomic mass of 101.07.In the periodic table, the elements are arranged in the order of their atomic numbers. In that sequence, the first element to have an atomic mass greater than 100 is Ruthenium (Ru), with atomic number 44.

According to the law of gravitation, how does the force of gravity relate to an
object's distance from Earth's center?
Answer:
Newton's universal law of gravitation says that the force acting upon (and therefore the acceleration of) an object toward Earth should be inversely proportional to the square of its distance from the center of Earth. It's this force of gravity on the surface of Earth that gives us our sense of weight.
Hope that helps
Answer:
The closer the object is to the center the stronger gravity acts on it. The further the object from the center the weaker gravity acts on it until it reaches a certain point where the gravity does not affect the object.

The main difference between ponds and lakes is that ponds?
A)are inland bodies of water
b)do not develop self-contained ecosystems
C)are smaller than lakes
d)have easily observed currents
Answer: C) are smaller than lakes
Explanation: EDGE 2020
The main difference between ponds and lakes is that ponds are smaller than lakes. So, the correct option is C.
What are Water bodies?A body of water or reservoir is defined as an accumulation of water on the surface of Earth or another planet, often refers to oceans, seas, and lakes, but also includes smaller pools of water such as ponds, wetlands, etc.
There are five oceans on the Earth which are as follows:
The Pacific OceanThe Atlantic Ocean The Indian OceanThe Arctic OceanThe Southern Ocean or Antarctic Ocean.A pond is described as an area filled with natural or artificial water, which is smaller than a lake.
Thus, the main difference between ponds and lakes is that ponds are smaller than lakes. So, the correct option is C.

Compare the structures of carbohydrates, lipids, proteins, and nucleic acid.
Answer: Biological polymers are large molecules composed of many similar smaller molecules linked together in a chain-like fashion. The individual smaller molecules are called monomers. When small organic molecules are joined together, they can form giant molecules or polymers. These giant molecules are also called macromolecules. Natural polymers are used to build tissue and other components in living organisms.
Generally speaking, all macromolecules are produced from a small set of about 50 monomers. Different macromolecules vary because of the arrangement of these monomers. By varying the sequence, an incredibly large variety of macromolecules can be produced. While polymers are responsible for the molecular "uniqueness" of an organism, the common monomers are nearly universal.
The variation in the form of macromolecules is largely responsible for molecular diversity. Much of the variation that occurs both within an organism and among organisms can ultimately be traced to differences in macromolecules. Macromolecules can vary from cell to cell in the same organism, as well as from one species to the next.
Explanation:
Answer:
Because they are all macromolecules?

A farmer ,sangay , plants chilli in the first year .He than plants beans in the same field next year ..
A. why does he do so ..
Answer/Explanation:
Chilli and Beans are two different groups of crops having different nutrient requirement for them to grow well.
Beans is a leguminous crop that can help fix nitrogen back to the soil after the soil nitrogen content has been depleted by crops that use up nitrogen in the soil.
So, one of the possible reasons why Sangay plants Chilli the first, and beans the next year could be to ensure optimal productivity, as beans would replenish the soil with nitrogen. Also, both crops have different nutrient requirement. Nutrient requirement for both crops vary.

Explanation:
A student wrote a sentence describing a difference between sexual reproduction and asexual reproduction.
Asexual reproduction requires two parents, and sexual reproduction requires one parent.
Which statement describes the student’s sentence?
Answer:
Asexual reproduction happens when organisms divide to reproduce, whereas sexual reproduction requires two organisms to mate to produce offspring.
Both processes are incorrect because asexual reproduction occurs when organisms divide to reproduce, whereas sexual reproduction requires two organisms to produce offspring.
What is Asexual and Sexual reproduction?Asexual reproduction is the process that produces offspring that are genetically identical to a single parent while sexual reproduction is defined as two parents contributing genetic information to produce unique offspring. Sexual and asexual reproduction have both advantages and disadvantages so some organisms do both!
Whereas sexual reproduction which involves sex cells and fertilization involves two parents to produce an offspring. For example – plants and animals like mammals. Sex cells and fertilization are not involved in asexual reproduction, so a single parent gives birth to the offspring. For example, amoeba, bacteria etc.
Thus, both processes are incorrect because asexual reproduction occurs when organisms divide to reproduce, whereas sexual reproduction requires two organisms to produce offspring.
