Answer:
Veins arteries and capillaries
The structures in the human body that carry out some of the same function as xylem and phloem are veins, arteries, and capillaries.
What do you mean by Xylem and Phloem?Xylem and phloem are the vascular tissues that transport water, minerals, and food from the roots to the leaves and from the leaves to the roots respectively.
Xylem and phloem represent homology with the veins and arteries. Veins carry blood back towards your heart, while arteries carry blood away from your heart.
Capillaries are blood vessels that carry the oxygen and nutrients from the blood and transport them into the tissues and organs. It also requires the elimination of the waste products away from your tissues.

A chemical change occurs when.
A the identity of a substance changes but its appearance does not.
B neither the appearance of a substance nor its identity changes.
C both the physical properties of a substance and its identity change.
D
the appearance of a substance changes but its identity does not.
Answer:
Im not 100 percent sure but I think C because a chemical change occurs when the chemical has broken composure so I think its C.
A chemical change occurs when both the physical properties of a substance and its identity change. The correct option is C.
What are chemical changes?A chemical change is a change when the identity of a substance changes, and it converts into a new substance with new characteristics and a new identity.
When iron comes in contact with oxygen, it changes into rust, and it is a chemical change. A chemical change is a transformation in which the substance's chemical composition is altered through atom rearrangement. Atomic alterations cause changes in the molecular structure.
Chemical properties are those property properties of a substance that does not depend on the quantity of that substance.
Therefore, the correct option is C. both the physical properties of a substance and its identity change.

How did gravity affect the growth of the germinating corn seeds?
Answer:
see below
Explanation:
their roots respond positively, growing down, into the soil, and their stems respond negatively, growing upward, to reach the sunlight.
Gravity influenced the growth of germinating corn seeds by providing the directional cue for root growth and promoting proper orientation of the plant.
Gravity plays a crucial role in plant growth and development, particularly during the germination of seeds. When a germinating corn seed is placed in a gravitational field, gravity acts as a guidance mechanism for the growing seedling.
In response to gravity, the root of the germinating seed grows in a downward direction, a process known as gravitropism or geotropism. This downward growth of the root is called positive gravitropism. The root responds to the gravity stimulus by redistributing auxin, a plant hormone, towards the lower side of the root. This causes cells on the lower side of the root to elongate more than cells on the upper side, leading to downward growth. The downward growth of the root helps anchor the plant in the soil and facilitates water and nutrient absorption from the ground.
Simultaneously, gravity also influences the shoot of the germinating corn seed. The shoot exhibits negative gravitropism, where it grows upward against the force of gravity. This upward growth is counterbalanced by the downward growth of the root, allowing the plant to establish proper orientation.
Without the presence of gravity, the germinating corn seeds would not be able to establish the proper orientation and direction of growth. The root may not grow downward, leading to irregular and inefficient water and nutrient absorption. The shoot may not grow upward, resulting in an abnormal and compromised overall plant structure.
Therefore, gravity serves as a crucial external factor that guides the growth of germinating corn seeds, ensuring proper root development, anchorage, and shoot orientation for successful plant growth.

A sample of DNA contains 120 nucleotides, if 35 nucleotides are Guanine, how many nucleotides are Thymine?
(If you can show how you do it that would be great)
Answer:
25
Explanation:
In DNA, Guanine pairs with Cytosine, and Thymine pairs with Adenine. This tells us that there are equal numbers for each Guanine and Cytosine, and Thymine and Adenine. When there's 35 Guanine, there should be 35 Cytosine that goes with it. 120 - 2(35) = 50. The remaining 50 nucleotides are Thymine and Adenine, and since they are the same number, divide 50 by 2. 50 ÷ 2 = 25. There are 25 thymine in the sample of DNA.
The section of dna being used to make the strand of mrna is known as a.
The section of DNA being used to make the strand of mRNA is known as the transcription unit.
What are transcription units?Transcription units are base sequences of DNA that make up a single mRNA molecule during the process of transcription.
During gene expression, genes are first transcribed to genetic codes in mRNA molecules before being translated to their respective proteins.
Each unit of transcription represents a gene along with non-coding base sequences in DNAs, otherwise known as introns.

Based on inheritance patterns, se_x-linked traits are present on the se_x chromosomes while autosomal traitsare found on the autosomes.
What is a dominant allele?A dominant allele is a copy of a gene which always appears in every generation.
A pedigree is a chart that shows the inheritance of triats in generations of families.
Based on the pedigree given:
The genotype of the individual #1 is XBXb since the offspring are XBXb and XbYIn the pattern of inheritance, all males receive their X chromosome from their mother.
Se_x-linked pedigrees differ from autosomal pedigrees because the traits are located on the se_x chromosomes.
