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.

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.

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.

Which two statements describe harmful effects of a tree dying and falling in a forest?
a. The space opened in the forest lets more light shine on plants that need it
b. Animals living in the tree's branches lose their shelter and nesting sites
c. The dead tree provides a new source of food for decomposers
d. Vines growing on the tree die if their stems and roots are damaged
The two statements that describe the harmful effects of a tree dying and falling in a forest are as follows:
Animals living in the tree's branches lose their shelter and nesting sites.Vines growing on the tree die if their stems and roots are damaged.Thus, the correct options are B and D.
Who consumes the dead plants fallen on the ground?The organisms that are known as decomposers consume the dead plants or trees which fall on the ground and convert the organic form of nutrients into inorganic ones.
The falling of trees in forests destructs the habitat of numerous birds and insects that are living on the trees. It is also responsible for the death of those plants whose stems require support in order to grow. Such plants are known as vines.
Therefore, the correct options for this question are B and D.

What percentage of the earth is comprised of algal beds & coral reefs? What
percentage of all marine species is found there?
Less than 1% of the Earth is comprised of algal beds and coral reefs, and 25% of marine species are found there.
Coral reefs and algae beds are ecosystems that need special conditions to survive; even though they are in a small percentage, a wide range of marine species live there.
As reefs need special conditions such as:
Warm waterCalm water currentsShallow waterThey are present only in 1% of the earth's surface since these conditions are not found easily in different parts of the world.
Even though the coral reefs and algae beds cover a small Earth's percentage, they are an ecosystem that is necessary for 25% of marine life, which equals 1 million species. Not all the species live there permanently; some use the algae beds or reefs at some moment and then leave. However, without these places, those species would not survive.
In conclusion, 1% of the Earth comprises algae beds and coral reefs, and 25% of all marine species are there.

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.
