how is the phloem in a leaf related to the roots of the plant?

a. cells that contain sugar move between the leaf and roots within the phloem. 

b. chloroplasts that make sugar move through phloem cells to the roots. 

c. water in the phloem cells comes to the leaf from the roots. 

d. sugar made in the leaf is carried to the roots by cells in the phloem.

Answers

Answer 1

Answer:

The phloem carries important sugars, organic compounds, and minerals around a plant. Sap within the phloem simply travels by diffusion between cells and works its way from leaves down to the roots with help from gravity. The phloem is made from cells called 'sieve-tube members' and 'companion cells'.

Answers

The uterus is a hollow muscular organ located in the female pelvis between the bladder and rectum. The ovaries produce the eggs that travel through the fallopian tubes. Once the egg has left the ovary it can be fertilized and implant itself in the lining of the uterus. The main function of the uterus is to nourish the developing fetus prior to birth.

Match the following enzymes involved in DNA replication with their functions.

a. DNA ligase
b. DNA polymerase
c. DNA gyrase
d. helicase

Answers

Answer:

DNA ligase is an enzyme which can connect two strands of DNA together by forming a bond between the phosphate group of one strand and the deoxyribose group on another.

DNA polymerase is an enzyme that synthesizes DNA molecules from deoxyribonucleotides, which are the building blocks of DNA. The enzymes play an essential role in DNA replication, usually working in pairs to produce two matching DNA stranges from a single DNA molecule.

DNA gyrase is an essential bacterial enzyme that catalyzes the ATP-dependent negative super-coiling of double-stranded closed-circular DNA

Helicases are enzymes that bind and may even remodel nucleic acid or nucleic acid protein complexes. There are DNA and RNA helicases. DNA helicases are essential during DNA replication because they separate double-stranded DNA into single strands allowing each strand to be copied.

Explanation:

DNA ligase seals the fragment, DNA polymerase adds a new nucleotide, DNA gyrase unwinds the DNA, and helicase makes a dent in double helix.

What is DNA replication?

DNA replication is the physiological method that generates two identical replicas of DNA from a single original DNA molecule in molecular biology.

DNA replication takes place in all living organisms and is the most important component of biological inheritance.

Helicase, primase, DNA polymerase, and ligase are the four main enzymes that aid in DNA replication.

Many proteins and enzymes play a role in DNA replication, including: Topoisomerase: This enzyme relaxes the super-coiled nature of DNA. Helicase: Helicase is a protein that separates the two strands of DNA at the replication fork.

The fragment is sealed by DNA ligase, a new nucleotide is added by DNA polymerase, the DNA is unwound by DNA gyrase, and a dent in the double helix is made by helicase.

Thus, this can be the match for the given scenario.

how do central nervous system and the peripheral nervous system work together to control the body?

Answers

The central nervous system includes the brain and spinal cord, while the peripheral nervous system includes all of the nerves that branch out from the brain and spinal cord and extend to other parts of the body including muscles and organs. Each part of the system plays a vital role in how information is communicated throughout the body.

The primary role of the PNS is to connect the CNS to the organs, limbs, and skin. These nerves extend from the central nervous system to the outermost areas of the body.

In conjunction with the central nervous system (CNS), the PNS coordinates action and responses by sending signals from one part of the body to another.

The general flow of information is that the peripheral nervous system (PNS) takes in information through sensory neurons, then sends it to the central nervous system (CNS) to be processed. After processing, the CNS “tells” the PNS what to do—what muscles to flex, whether the lungs need more oxygen, which limbs need more blood, any number of biological processes—and the PNS makes it happen through muscle control. The neurons responsible for taking information to the CNS are known as afferent neurons, while the neurons that carry the responses from the CNS to the PNS are known as efferent neurons.

Shameeka is studying for an exam. She took the notes below about calcium and chlorine, which are known to form ionic bonds.

Calcium, which is a metal, donates 2 electrons to chlorine.
The individual calcium atoms become ions with a negative 2 charge.
The bond between calcium and chlorine makes the atoms stable.
Calcium and chlorine attract each other.

Which best describes Shameeka’s error?

Calcium is a metal, so it donates protons, not electrons.
The individual calcium atom has a positive, not negative, 2 charge.
The bond formed makes the atoms unstable, not stable.
Calcium and chlorine repel, not attract, each other.

Answers

Answer:

The individual calcium atom has a positive, not negative, 2 charge.

Explanation:

The error in her study is in the second line of her note which suggests that the individual calcium atoms becomes ions with a negative 2 charge.

When atom loses electrons, it has a net positive charge on it. Not a negative charge. This is because the number of protons is now more than electrons. Therefore, a net charge on the calcium atom will be a positive one. This is her mistake.

Answer:

B) The individual calcium atom has a positive, not negative, 2 charge.

what is the function of RBC

Answers

Answer:

When a red blood cell is placed in a hypertonic solution, it contracts as water is drawn out of the cell and into the surrounding solution. If the same blood cell is placed in a hypotonic solution, the blood cell grows in size. Blood cells in isotonic solutions do not shrink or swell.

The reason that blood cells change in size when placed in a solution with different salt concentration is due to the osmosis process. Osmosis causes solutions with high concentrations of salt to draw water from areas with low concentrations of salt.

There are some exceptions to this phenomenon. Blood cells can draw water and explode when placed in hypertonic solution on some special occasions. Some diseases affect the structural integrity of blood cells. Also, when human blood cells are exposed to temperatures close to freezing, they can draw water and explode.

Osmosis is an important phenomenon for living systems. The amount of salt in a given solution exhibits a tendency to diffuse through the environment, eventually resulting in equilibrium. In addition to blood cells, the kidneys function through the use of osmotic principles. The kidneys filter an animal's blood to remove excess salt and balance the amount of water

How is the age distribution pattern of the Hawaiian Islands - Emperor Seamount chain explained by the position of the Hawaiian hotspot? Explain using evidence and reasoning.

Answers

Answer:

Find the explanation below.

Explanation:

The Hawaiian Islands is a series of islands positioned in what looks like a chain, which increases in age as one moves northwest. The Hawaiian hotspot was formed as a result of the collision of the tectonic plates in the outer part of the earth which caused the rise of a volcano, and which in turn gave off magma which came to rest on a seafloor. That eruption on the seafloor is the hotspot.

This hotspot remains unmovable while the tectonic plates are in constant motion around the hotspot, giving rise to further Islands. This explains the age distribution pattern of the Hawaiian islands which arrived at different times making some older than the others.
