Answer:
Sodium
Explanation:
This would leave you with 3 shells of 2, 8, and 1. Since it has one more shell then the second shell has to be 8. Since the first shell can only contain up to 2 it must be 2/8. And since it has one less valence electron than beryllium it must be a config of 2/8 1, which is the electron config of Sodium, Element with Atomic number 11 and electron shell of 2/8 1.

why do some root cell have root hair
Answer:
Root hairs form an important surface as they are needed to absorb most of the water and nutrients needed for the plant. They are also directly involved in the formation of root nodules in legume plants. ... Having a large surface area, the active uptake of water and minerals through root hairs is highly efficient.
Answer:
Explanation:
Root hairs appear when the epidermis differentiates. The epidermis has specialized cells that are root hair cells. Much attention has been given to root hairs because of their presumed importance as absorbing surfaces.

Answer:
It hast be protein
Explanation:
Answer:
Protein
Explanation:
Proteins provide strength,structure,and support for the body.
These structures are found in the nucleus of dividing cells they appear x -shapped
Answer:
Because each duplicated chromosome consists of two identical sister chromatids joined at a point called the centromere, these structures now appear as X-shaped bodies when viewed under a microscope. Several DNA binding proteins catalyze the condensation process, including cohesin and condensin.

Which statements represent convection? Select two options. Black asphalt gets very hot on a sunny day. The movement of air in a hot-air balloon makes it rise into the sky. A dark sand beach can burn the soles of your feet. A spoon gets warm from sitting in a soup pot. A house has high heating bills because the heat ends up in the attic. A house loses heat through an exterior wall.
Answer:
B. and E. are the correct answer because convection is the movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat.
Explanation:
hope this helps
Convection is a heating transmission process. The options are B) The movement of air in a hot-air balloon makes it rise into the sky, and E) A house has high heating bills because the heat ends up in the attic.
What is convection?Convection is a natural process that results from heating transmission between two substances.
The change in temperature between these substances produces a change in density as well, and hence, the movement of the substances.
The cyclic circular ascending and descending motion of materials as they get heated or cooled is known as convective currents.
Among the options, the correct statements are,
B) The movement of air in a hot-air balloon makes it rise into the sky.
E) A house has high heating bills because the heat ends up in the attic.

What is one of the energy transformations that takes place during cellular respiration
energy to
energy
One of the energy transformations that take place during cellular respiration is the conversion of chemical energy in carbohydrates into usable cellular energy in the form of ATP.
During cellular respiration, the bonds holding carbohydrate molecules in foods together are broken down and the energy in the bonds is converted to usable energy by cells, in the form of ATP.
Cellular respiration takes place in a series of reactions, but the summary is represented in the equation below:
[tex]C6H12O6 + 6O2 ---> 6CO2 + 6H2O + energy[/tex]

Cellular Respiration and photosynthesis are related in that they are opposite of each other. The products of one process are the reactants of the other.
True
False
Answer:
This statement is true.
Explanation:
because during photosynthesis , oxygen is produced because of the reaction of carbon dioxide, and water in the presence of sunlight. oxygen and glucose are synthesized during photosynthesis while on the other hand, oxygen is used in respiration and carbon dioxide is produced which again used by plants.
Explain the relationship between coral and algae, and how a problem with algae photosynthesis caused coral bleaching in the Great Barrier Reef.
How did water from the Great Barrier Reef affect ATP, NADPH, and sugars?
explain how you know that paraquat did not cause the coral bleaching.
Explain why you know that diuron caused the coral to bleach.
Answer:
mutualistic relationship.
paraquat is a herbicide.
Diuron is a algaecide.
Explanation:
mutualistic relationship is present between coral and algae. Paraquat did not cause the coral bleaching because paraquat is a herbicide which is used to kill weeds not algae. We know that coral have small algae attached to its body which is responsible for its colour so if we apply paraquat, it does not kill the algae and so coral bleaching did not occur. if we apply diuron which kills algae so it causes coral bleaching and the coral becomes white.
