How does a sperm cell get to an egg?
A. It travels through
water.

B. It is carried by a
pollinator.

Answer:

C

Explanation:

glucose is polar, meaning that there is a separation of charge present in the observed molecule

water is also polar as it contains electronegative oxygen, which pulls electrons towards itself,  forming a dipole of partial positive (H) and partial negative charge (O)

a simple rule of thumb is "like dissolves like"

Glucose dissolves in water because it is polar. Therefore option C is correct.

Glucose, a simple sugar, and a monosaccharide is a polar molecule, meaning it has a slight positive charge on one end and a slight negative charge on the other due to its asymmetrical arrangement of atoms.

Water molecules are also polar, with a positive end (hydrogen) and a negative end (oxygen). Like dissolves like, so the polar nature of glucose allows it to interact with water molecules through hydrogen bonding, effectively surrounding and stabilizing glucose molecules in solution.

This enables glucose to dissolve in water, forming a homogeneous mixture and allowing it to be transported and utilized within living organisms for energy production and other essential processes.

Therefore option C is polar is correct.

To breed crops with uniform growth and maturity.

To meet particular needs of growers and consumers.

Answer:

False.

Explanation:

A negative charge dies not represent positive numbers because a negative charge represent negative number.

Electrons are negative charge and they represent negative numbers like -1, - 2, et.c. protons represent positive charges and when to negative charges come together, they repel each other likewise positive charges but if negative charges and positive charges come together, they attract each other.

Explanation:

1) When a rock is exposed to heat and pressure, it becomes a metamorphic rock. This is correct, because this is the process that forms a metamorphic rock.

2) A rock becomes sediment through weathering and erosion. In this question, they are not asking you to explain the process of sedimentary rock formation, they are asking you how a rock becomes sediment. The process of weathering and erosion breaks down a rock, and turns that rock into smaller peices, which therefore, through the process of compaction and cementation forms a sedimentary rock.

3) A fern is a land plant. It is not found in the sea and there is not enough information given to tell whether or not the area was hot or cold. This leaves us with D. We can tell that this fossil is a land fossil because ferns do not grow in the ocean.

Explanation:

DNA replication is the process by which a DNA molecule makes a copy of itself i.e. duplicated. In this process, the double-stranded DNA molecule splits into two single strands, which each serves as template for the synthesis of another strand. The new strand is synthesized using the COMPLEMENTARY BASE PAIRING RULE.

Complementary base pairing rule states that an Adenine base will always hydrogen bond with a Thymine base while Guanine base will always hydrogen bond with Cytosine base i.e. A-T, G-C. Hence, given the original strand of DNA in this question, the complementary strand will have the following sequence: 3’ TAT CAC GGG TTG CCA 5’

Answer:

They have the same primary DNA but may have different plasmids.

Explanation:

i took a test and got the question right

The option that's true about the two daughter cells formed after the binary fission of a bacterium cell is D. They have the same primary DNA but may have different plasmids.

Binary fission simply means asexual reproduction when a body is separated into two different bodies.

It should be noted that during binary fission, the genetic material of an organism is duplicated and this enables the two new organisms formed to be able to have their separate copy of DNA.

In a bacterium cell, when the two daughter cells are formed after the binary fission, they have the same primary DNA but may have different plasmids.

Answer: Evolution is considered to be a scientific theory because evolution is not proven true of false, although it is widely recognized as true. A theory is defined as "a system of ideas intended to explain something, especially one based on general principles independent of the thing to be explained", meaning that it is the compliation of a certain ideas in hopes of proving something as true. The theory of evolution is the use of facts to try to explain how species have evolved over time. We have been unable to prove evolution as it occurs in front of us, but we can use evidence to support this theory.

Explanation:

The process whereby a mRNA molecule is formed from a DNA template is called TRANSCRIPTION. The mRNA formation follows the complementary base pairing rule which says that Adenine is bonded to Thymine (Uracil in RNA) i.e A-T(U) while Guanine is bonded to Cytosine i.e. G-C.

Based on this, a DNA molecule with base sequence: CTTAACACCCCTGACTTCGCGCCGTCG will be transcribed into a mRNA strand with base sequence: GAAUUGUGGGGACUGAAGCGCGGCAGC
