Answer:
The dermal tissue system protects the soft tissues of plants and controls interactions with the plants' surroundings. The epidermis is a dermal tissue that is usually a single layer of cells covering the younger parts of a plant. It secretes a waxy layer called the cuticle that inhibits water loss.
Primary dermal tissues, called epidermis, make up the outer layer of all plant organs (e.g., stems, roots, leaves, flowers). They help deter excess water loss and invasion by insects and microorganisms.

Explain how roots hair cells use osmosis to take up water.
Answer:
Plants absorb water from the soil by osmosis. They absorb mineral ions by active transport, against the concentration gradient. Root hair cells are adapted for taking up water and mineral ions by having a large surface area to increase the rate of absorption.

Which arthropods are a part of the class maxillopoda?
And
What are hexapods distinguishing characteristics?
Answer:
a) Maxillopoda is a diverse class of crustaceans including barnacles, copepods and a number of related animals. It does not appear to be a monophyletic group, and no single character unites all the members
b) General Characters of Hexapoda (Insects)
Ø A large taxa, includes insects and a small group of wingless arthropods.
Ø Body plan: 3 parts, head, thorax and abdomen.
Ø Head with six segments.
Ø Thorax with three pairs of jointed legs (hence the name hexapoda)
Ø Head bears a presegmental acron.
Ø Acron bears compound eyes.
A 3 base section of mRNA. The ribosome reads 1 codon at a time; translation of a new protein always begins with _________, or Methionine, the START codon, and ends with a STOP codon.
Answer:
The start codon is AUG
Explanation:
A three nucleotide sequence (represented with bases) of a DNA or a RNA which translates to a specific amino acid is referred to as codon. To begin the translation into a new protein, the first three nucleotide is always AUG (called the START codon) which is the codon for methionine.
NOTE: AUG is the initial of the bases; Adenine, Uracil and Guanine

helium is an element..............
Answer:
A. Element
Explanation:
He is a symbol of an element called helium. Helium is a colorless, odorless, tasteless, non-toxic, inert, monatomic gas (gas whose atoms are not bound to each other). It's the first in the noble gas group in the periodic table. As we can see in the attached image, its atomic number is 2.
Helium is known for causing people to have a high-pitched voice after being inhaled. Because it is lighter than air, when you inhale it and try to talk, the sound waves travel faster through the lower-density gas, resulting in a high-pitched voice.

what process causes water to move in and out of the central vacuole? explain
Answer:
In plant cells, osmotic pressure can cause changes in the size of the central vacuole, which shrinks or swells as water moves into or out of the cell.
Explanation:
Hope this helped, Have a Great Day/Night!!
Answer:
Function of the Central Vacuole
Turgor pressure changes in a cell due to osmosis, which is the diffusion of water into or out of the cell. When a plant cell is in a hypotonic solution, there is a higher concentration of water molecules outside the cell than inside, and water will flow into the cell.

“Chad is attempting to determine how different colors of light
affect plant growth. Chad places one spider plant in a cabinet
under a blue light and one spider plant in a cabinet under a red
light. Chad knows he needs to compare his plants to a plant
grown under white light so he places a third spider plant on the
window sill where the sun shines. All plants are the same age
and are given equal amounts of light time, plant food and water.
At the end of a two week period, Chad will measure the height of
each plant.”

Answer:
In humans, a zygote will develop into a female if the sperm that fertilizes the egg has an X sex chromosome.
Explanation:
The sex chromosomes contributed by the man are sexual determinants, since his gametes —sperms— possess both the X and Y sex chromosomes. In contrast, the eggs only possess the X sex chromosomes.
Male XYFemale XXIf an egg is fertilized by a sperm carrying the X sex chromosome, the zygote will have one pair of X chromosomes that will determine the female sex in the product.
Which statement below best describes the role of mutations in evolution by natural selection?
A Mutations increase the genetic variation within a population, and each of the variants provides an advantage under different circumstances
B Mutations increase the genetic variation within a population, and some of the variants may provide an advantage to individuals over time
C Mutations help stabilize the genetic variation within a population, and only one or two variants generally provide an advantage to individuals.
D Mutations help reduce the genetic variation within a population, and thus increasing the rate that new adaptations develop.
Answer:
B. Mutations increase the genetic variation within a population, and some of the variants may provide an advantage to individuals over time
The role of mutations in evolution by natural selection is option b. Mutations increase the genetic variation within a population.
Role of mutation in evolution:The mutation is significant as the first step of evolution since it developed the new DNA sequence for the specific gene that developed the new allele.
Also, at the same time, it rise the genetic variation within the population also it provides as an advantage to individual
hence, the option b is correct.
